DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape cassette.

[0002]

2. Description of the Related Art In general, a tape cassette used by being mounted on a recording and / or reproducing apparatus such as a video tape recorder or the like has a housing in which a pair of reels around which a magnetic tape is wound are rotatably housed. Is provided with a detected part for preventing erroneous erasure. A label is affixed to the rear surface or one side surface of the tape cassette and in the vicinity of the detected portion, and a title or the like of the content recorded on the magnetic tape is described here in characters.
This is because the contents recorded on the magnetic tape in the tape cassette can be understood at a glance from the outside without mounting the tape cassette in the apparatus.

[0003] By the way, when this kind of tape cassette is used for home use, once recorded contents are erased and re-recorded from the viewpoint of economy, except for those which are permanently stored, it is possible to use the tape cassette again. It is being done as it is. In this way, if you want to erase the content recorded on the magnetic tape in the tape cassette once and record another content on it, you need to remove the label and attach another label as a matter of course. There was a drawback that was extremely inconvenient to use.
Furthermore, with the rapid progress of magnetic tapes, it has become possible to cope with longer time, and the content recorded there has become considerably larger depending on the mode setting. It's getting harder to put everything in there.

[0004]

Therefore, in order to eliminate such a conventional defect, for example, a label attached to a back surface of a tape cassette in which a recording medium such as a conventional magnetic tape is stored is provided in the vicinity of a detected portion for preventing erroneous erasure. Of the memory or the like having substantially the same shape as the end portion at the end of the concave portion and on the side of the detected portion.
The applicant of the present invention has previously disclosed a tape cassette in which an IC package made of a small piece of resin encapsulating C is mounted.
No. 125157. Here, the contents of the previous application will be described with reference to FIGS.

FIG. 1 is a side view of a VHS (registered trademark) type tape cassette 1 in which, for example, a pair of reels around which a magnetic tape (not shown) is wound is housed in a housing in a rotatable manner. FIG. 3 is a plan view of an IC package attached to a concave portion (attached portion) of the tape cassette, FIG. 3 is a detailed view of FIG. 2, (A) is a plan view thereof, (B) is a side view thereof; (C) is the same, rear view, FIG.
Is to insert the IC package 5 into the concave portion 2 of the tape cassette 1,
FIG. 3 is a side view of the tape cassette 10 showing, for example, a state where the tape cassette 10 is attached. In FIG. 1, reference numeral 2 denotes a concave portion having a width L1 formed over substantially the entire side surface of the tape cassette 1. The recess 2 has a size and a shape in which a label 3 having the same shape as that of the related art, for example, in which the recorded content is described, is attached, for example, and at least two of the four edges are formed. A curved surface portion (2e, 2f) is formed on the ridge. (FIG. 1 shows a state in which the label 3 is stuck in the concave portion 2.) The tape cassette 1 is
Although not shown, it is configured by combining the upper half and the lower half. Numeral 4 is a detected portion for preventing erroneous erasure provided near one end 2a of the concave portion 2. As is well known, when the wall portion 4a is not broken off, erasing is possible. If so, it is configured so that it cannot be erased.

FIGS. 2 and 3 are plan views of a rectangular IC package formed of, for example, a resin material, showing an upper surface 5a and terminals 6 embedded in a substantially lower half of the upper surface 5a.
And a pressure-sensitive adhesive 7 provided on the upper and lower ends of the lower surface 5i.
a and 7b. 5b is this IC
For example, identification portions 5c and 5d formed at the upper right portion of the package 5 and at positions separated from the terminals 6 and formed by oblique sides so that upper, lower, left and right can be identified are formed at upper and lower ends, respectively. It is the step which was done. 5e, 5f
Are curved portions formed on the lower left and upper left ridges (corners), respectively. The curved surfaces of the curved portions 5e and 5f are formed in the same shape as the curved surface of the end of the label 3 shown in FIG. 5g is a curved surface portion 5e, 5
5h is a right side portion connected to one side of the hypotenuse portion 5b and one side of the step portion 5c.

Here, the specific structure of the terminal 6 will be described. For example, reference numeral 6a denotes a ground terminal connected to a connection terminal (not shown) of the apparatus, and 6b denotes a control signal
A terminal portion for control signal 1;
6d is configured to function as a power supply terminal.

Next, a specific structure of the lower surface 5i of the IC package 5 will be described with reference to FIGS. 7a and 7b are pressure-sensitive adhesives provided on the upper and lower ends of the lower surface 5i, respectively, as described above.
The middle part 7c of the parts 7a and 7b does not have a pressure-sensitive adhesive layer. As described above, this type of tape cassette is constructed by combining the upper and lower halves. However, it is difficult to accurately match the seam in the molding. If it is displaced compared to the other (a state in which the joining surfaces do not exactly match and one is dented by the other), that portion floats, and the smoothness of the pressure-sensitive adhesive is increased by reducing the contact area. It is like that. Note that the terminal 6 is completely embedded inside the IC package 5,
It is formed so that the surface of the upper part 5a of the IC package 5 coincides. The overall shape of the IC package 5 is formed to be slightly smaller than the shape of the concave portion provided on the side surface of the VHS (registered trademark) tape cassette 1 described above.

The overall thickness of the IC package 5 is such that the IC package 5 is mounted at a predetermined position in the concave portion 2 of the tape cassette 1 and then mounted on a device (not shown), and the connection terminals provided on the device side and the IC package. 5 is formed to be slightly larger than the thickness of the concave portion 2 because signals are transmitted and received when the terminal 6 is connected to the terminal 5. Step 5
c and 5d are, for example, such thicknesses as to divide the entire thickness of the IC package 5 into approximately two equal parts. Therefore, in this case, as a matter of course, the thickness of each of the step portions 5c and 5d, which are approximately equal to each other, is formed to be smaller than the thickness of the concave portion 2. The tape cassette 1
When the IC package 5 is stored in the concave portion 2 by providing a storage portion for storing the step portions 5c and 5d in a portion corresponding to the step portions 5c and 5d in the concave portion 2 of FIG.
Since the steps 5c and 5d function as a guide, they can be smoothly mounted and detached. In this case, since the IC package 5 is securely housed in the housing, the pressure-sensitive adhesive is not necessarily required. Further, since the IC package 5 is formed of a resin, it can be colored and printed, and the IC package itself can be provided with identification information in colors and characters.

FIG. 5 is a side view of another embodiment of the tape cassette 20 containing a high-performance magnetic tape, for example. In the description of FIG. 5, the same components as those described above are denoted by the same reference numerals, and a specific description thereof will be omitted. Numeral 7 denotes a notch provided at the same position as the erroneous erasure detection target portion 4 provided in the tape cassettes 1 and 10 shown in FIGS. 1 and 4 above. Is mounted on a recording / reproducing apparatus for general tape cassettes 1 and 10 in which ordinary magnetic tapes are incorporated, the general-purpose recording / reproducing apparatus is used.
When the erroneous erasure preventing claw detecting means provided in the reproducing apparatus detects the notch 7, the magnetic head provided in the apparatus records the high-performance magnetic tape contained therein. It is for preventing.

Reference numeral 8 denotes an IC package 5 having a built-in terminal 6.
Is a recess for accommodating the
8 has an end portion 8a formed at the same position as the end portion 2a of the concave portion 2, and has curved surface portions 8e and 8f on at least two ridges (corners) as described above. It has been formed. The recess 8 is formed in the same shape as the IC package 5 and slightly larger in size than the recess described above. The width L1 is formed so as to be slightly larger than the width L2 of a label mounting groove 9 described later.

Reference numeral 9 denotes a label mounting groove formed with a space T from the concave portion 8. The groove 9 has a width L2 slightly smaller than the width L1 of the concave portion 8, and has four ridges. Curved surface portions 9a, 9b, 9c, 9d of the same shape are formed respectively. In the tape cassette 20 according to the other embodiment, it is needless to say that a label having a size corresponding to the groove 9 is attached thereto.

The operation of mounting the IC package 5 in the recess 2 of the tape cassette 10 will be described with reference to FIGS. First, the IC package 5 is gripped so that the oblique side portion 5b, which is an identification portion formed at the upper right portion of the IC package 5, is located on the upper side, and then formed on the lower left and upper left ridges (corners), respectively. Curved surface part 5
e, 5f and the left side surface portion 5g are adhered so as to coincide with one end 2a and the curved surface portions 2e, 2f of the concave portion 2 having the width L1. In this case, as described above, the shape of the curved surface portion and the like of the IC package 5 is the same shape as the concave portion 2 and slightly smaller than the concave portion 2, and furthermore, due to the synergistic action with the oblique side portion 5 b for identification, It can be securely attached to a predetermined position (see FIG. 4). At this time, since the pressure-sensitive adhesive layers 7a and 7b are provided on the lower surface 5i of the IC package 5, the IC package 5 does not need to use any other attaching means, which is very convenient.

Similarly, the operation of mounting the IC package 5 containing the terminal 6 in the recess 8 of the tape cassette 20 will be described with reference to FIGS. First, the oblique side portion 5 which is an identification portion formed in the upper right portion of the IC package 5
Then, the IC package 5 is gripped so that the b is on the upper side. Thereafter, the curved surface portions 5e and 5f and the left side surface portion 5g formed on the lower left and upper left ridges (corners) are respectively inserted into the concave portions 8 having the width L1. Is adhered so as to match one end 8a and the curved surfaces 8e and 8f. In this case, as described above, the shape of the curved surface portion and the like of the IC package 5 is the same as the concave portion 8 and slightly smaller than the concave portion 8, and the width shape of the concave portion 8 and the groove portion 9 is different. In addition, by the synergistic action with the shape of the oblique side portion 5b for identification, it can be securely attached to a predetermined position (see FIG. 5). At this time, the pressure-sensitive adhesive layer 7 is provided on the lower surface 5i of the IC package 5.
Since the IC package 5 is provided with a and 7b, the IC package 5 does not need to use other attaching means as described above, so that it is very convenient.

As described above, the IC package 5 is located at a predetermined position.
The tape cassettes 10 and 20 to which are attached are mounted at predetermined locations on the device side (not shown), so that the terminal portions 61 to 64 of the terminals 6 of the IC package 5 are connected to contact points (not shown) on the device side. As a result, the content recorded on the magnetic tape by, for example, a pen input device or a character input device provided on the device side can be easily recorded in the IC package 5. The input of the recorded contents can of course be performed by connecting an external device such as a personal computer.

In this embodiment, the detected portion 4 for preventing erroneous erasure and the concave portion near the notch 7 (label-attached portion).
Has been described with an example in which the IC package 5 is attached to a part of
The present invention is not necessarily limited to this, and it goes without saying that the concave portions and the groove portions may be provided at appropriate positions according to the connection terminals on the device side.

[0017]

The above-mentioned I
The C package is provided with terminals for transmitting and receiving information signals by being connected to contact points on the device side. However, when this IC package is mounted at a position different from the proper mounting position, There is a problem that leads to breakage of the IC package. That is, in the IC package configuration of FIG. 3A, the terminal portion of the IC package and the contact portion on the device side have a regular connection relationship, for example, the ground terminal portion of the IC package and the contact portion on the device side. When connected, the regular power supply voltage is applied to it,
This is because, in the case of an incorrect connection, the IC is destroyed by applying a voltage different from the power supply voltage to which it should be applied. To explain this point in detail, the IC package 5 as shown in FIG. 2 and FIG. 3 (A) is correctly attached, that is, in the concave portion 2 of the tape cassette 1 so that the identification portion 5b is arranged at the upper right. In this case, the connection portion of the terminal 6 is connected to a contact portion (not shown) on the device side, and the content recorded on the magnetic tape can be correctly recorded in the IC package 5. However, a problem occurs when the IC package 5 is stuck in the concave portion 2 of the tape cassette 1 in a wrong direction.

That is, as described above, the terminal 6 uses the terminal 6a for grounding, the terminal 6b for control signal 2, the terminal 6c for control signal 1, and the terminal 6d for power supply. However, when this is adhered in the opposite direction, the power supply terminal 6 on the IC package 5 side is used.
d and the grounding terminal 6a are arranged in reverse. For example, the grounding terminal 6a on the IC side is connected to the power supply contact on the device side, so that the built-in terminal is provided. This is because the IC is destroyed when a voltage different from the power supply voltage to be originally applied is applied to the ICIC package. The present invention has been devised in order to eliminate such a conventional disadvantage. For example, the present invention is provided near a detected portion for preventing erroneous erasure on the back surface of a tape cassette in which a recording medium such as a conventional magnetic tape is stored. When attaching an IC package consisting of a small piece of resin encapsulating an IC such as a memory having substantially the same shape as this end at the end of the concave portion where the label is attached, and on the side of the detected part, an incorrect This problem has been solved by providing an identification section so that the IC is not damaged even if the IC card is mounted in a different direction from the direction, and using a tape cassette with a specially designed terminal section.

[0019]

That is, according to the present invention, a pair of reels each having a magnetic tape wound thereon are rotatably housed in a housing, and are mounted on a rear surface of the housing in the vicinity of a detection portion for preventing erroneous erasure. A mounting portion is provided, and is formed in a square shape at an end of the mounted portion and on the side of the detected portion, and is separated from the terminal portion provided at a substantially central portion of the square. And a discriminating portion for preventing erroneous sticking provided at a corner of the square, and the terminal portion is protected from damage of the built-in element even when it is erroneously stuck. An object of the present invention is to provide a tape cassette to which IC packages arranged in various arrangements are attached.

[0020]

The same components as those described above are denoted by the same reference numerals, and a specific description thereof will be omitted. Numeral 6 denotes a terminal, which is arranged at a substantially central portion of the IC package 5 unlike FIGS. 2 and 3 described above. For example, the terminal is constituted by a terminal 61 for the control signal 2 and a terminal for the power supply. 62, a terminal 63 for the control signal 1, a terminal 64 for the ground, and the like.

FIG. 7 is a plan view of the tape cassette 30 showing a state in which the IC package 5 of FIG. 6 is correctly attached to the concave portion 2 of the tape cassette 1 as shown in FIG. The IC package 5 is inserted into the recess 2 of the tape cassette 1.
Since the sticking operation to stick to is the same as the method described above,
It is not described again here.

Further, the tape cassette 30 to which the IC package 5 having the terminals 6 in which the predetermined terminal portions 61 to 64 are disposed in the substantially central portion is mounted from a predetermined portion of the apparatus (not shown). IC package 5
Are connected to contact points (not shown) on the device side. As a result, the content recorded on the magnetic tape by, for example, a pen input device or a character input device provided on the device side can be easily recorded in the IC package 5. The input of the recorded contents can of course be performed by connecting an external device such as a personal computer.

By the way, according to the tape cassette structure of the present invention, the IC package 5 as shown in FIG. 6 is correctly attached, that is, the concave portion 2 of the tape cassette 1 is arranged so that the identification portion 5b is arranged at the upper right. When affixed inside
Since the terminals 6 are correctly connected to contact points (not shown) on the device side, the contents recorded on the magnetic tape can of course be correctly recorded in the IC package 5. For example, even if it is stuck in the concave portion 2 of the tape cassette 1 in the wrong direction, no problem occurs.
Hereinafter, this point will be described in detail.

FIG. 8 is a side view of the tape cassette 30 showing a state in which the IC package 5 is stuck in the concave portion 2 of the tape cassette 1 in a wrong direction. In other words, when the identification unit 5b in the wrong orientation of the IC package 5 is attached to one end 2a of the recess 2 at the lower left and in the vicinity of the detection unit 4, the control is performed. Terminal part 61 for signal 2
Since the positions of the ground terminal 64 and the ground terminal 64 are reversed, the ground terminal 64 and the contact for control signal 2 provided on the device side, which are not connected properly, are connected. In that case, a voltage enough to destroy the IC is not applied, so that the built-in IC is not destroyed. The terminal 6 shown in FIG.
In the arrangement example, even if the control signal 1 and the control signal 2 are interchanged, no problem occurs for the same reason as described above.

FIG. 9 shows a tape cassette 30 according to the present invention.

In the case of the present invention, there is a part where the pitch has an error and the part is not connected. In this case, a voltage different from the power supply voltage is not applied to the IC package 5 side because the power supply contact portions are not connected. Therefore, according to the other embodiments, even if the IC package 5 is stuck in a predetermined recess of the tape cassette by mistake, a voltage different from the power supply voltage which should be originally applied to the built-in IC is applied. There is no danger and the IC will not be destroyed. That is, this IC is protected from electrical destruction when energized.

FIG. 10 shows a tape cassette 4 according to the present invention.
FIG. 4 is a plan view of an embodiment of the IC package 5 attached to a predetermined position of a concave portion 2 of the IC package 5; In the embodiment shown in FIG. 10, the same components as those described above are designated by the same reference numerals, and a detailed description thereof will be omitted.
