A hook-like protrusion connected to any one of the recessed portion and the stepped portion and any one of the recessed portion and the stepped portion and protruding outward along a first direction which is the extending direction of the upper surface; And a discharge port provided at the bottom surface for discharging the liquid.

  According to this application example, the liquid container is connected to the recess or step portion provided on one end side of the upper surface, and includes a hook-like protrusion that protrudes outward along the extension direction of the upper surface. Therefore, for example, if a jig that engages with the hook-like protrusion is used, the liquid container is held on a flat plate with the upper surface facing downward so that the discharge port provided on the bottom surface faces upward. be able to. In addition, since the recess or step is provided so as to be recessed on the bottom side, the shape of the liquid container is such that the hook-like protrusion is on the upper side of the upper surface (the upper surface is on the lower side and the liquid container is disposed on a flat plate) In the state where it is in, it can be made the shape which protrudes in the lower part side of the upper surface and does not interfere with a flat plate. Thus, the liquid container can be stably held on the flat plate, and the liquid can be injected into the liquid container from the discharge port.

  Application Example 4 The liquid ejecting apparatus according to this application example includes the liquid container described above, a mounting member that detachably holds the liquid container, and the liquid contained in the liquid container. And a liquid jet head jetted to the member.

  According to this application example, the liquid ejecting apparatus can inject the liquid and eject it repeatedly on the recording member when the liquid contained in the liquid container is exhausted. In addition, since the liquid container is provided with the projecting part, when the liquid container is attached to and detached from the mounting member, the mounting direction to the mounting member can be easily determined.

[Printer Configuration]
FIG. 1A is a perspective view showing the main configuration of a printer as a liquid ejecting apparatus according to a first embodiment. FIG. 1B is an assembled cross-sectional view of the mounting member on which the liquid container according to the first embodiment is mounted. FIGS. 1A and 1B show XYZ axes which are coordinate axes orthogonal to each other. In the present embodiment, the printer 1 is used in a state where the printer 1 is disposed in a horizontal plane (XY plane) defined by the X axis as the second direction and the Y axis as the first direction. . The attitude of the printer 1 when the printer 1 is disposed on the XY plane is referred to as the use attitude of the printer 1.

  The Z axis is an axis orthogonal to the XY plane, and the direction along the Z axis is the vertical direction when the printer 1 is in use. Then, in the use state of the printer 1, in FIGS. 1A and 1B, the −Z direction is the vertically downward direction. In each of the XYZ axes, the direction of the arrow indicates the + (positive) direction, and the direction opposite to the direction of the arrow indicates the-(negative) direction.

  First, a schematic configuration of main parts of the printer 1 according to the first embodiment will be described with reference to FIG. 1A. The printer 1 includes a recording unit 10, a drive unit 20, and a control unit 30. The recording unit 10 includes a carriage 11 as a mounting member for mounting a cartridge 101 as a liquid container, and a liquid jet head 12, and performs a printing operation on a recording medium P as a material to be recorded.

  The cartridge 101 contains ink as a liquid. The cartridge 101 is mounted on the carriage 11, and the ink is supplied from the cartridge 101 to the liquid jet head 12. The liquid jet head 12 is mounted on the carriage 11. The liquid jet head 12 jets the ink to the recording medium P under the control of the control unit 30 described later. Further, the control unit 30 records the remaining amount of the ink contained in the cartridge 101 from the ejected amount of the ejected ink.

  The drive unit 20 reciprocates the carriage 11 along the X direction, which is the main scanning direction D1, and the paper feed driving unit 21 which feeds the recording medium P along the Y direction, which is the sub scanning direction D2. ,have. The control unit 30 is connected to the drive unit 20 by a cable (not shown), and controls a motor and the like mounted on the paper feed drive unit 21 and the carriage drive unit 22.

  The paper feed drive unit 21 conveys the recording medium P in the sub scanning direction D2 under the control of the control unit 30. The carriage drive unit 22 moves the carriage 11 along the main scanning direction D1 under the control of the control unit 30. Printing on the recording medium P is performed by ejecting ink from the liquid ejecting head 12 to the recording medium P conveyed in the sub scanning direction D2 while the carriage 11 moves along the main scanning direction D1. The printer 1 can print photos and the like on the recording medium P by continuously performing this printing operation.

[Configuration of recording unit]
Next, the configuration of the recording unit 10 will be described using FIG. 1B. The recording unit 10 includes a carriage 11 and a liquid jet head 12 disposed on the recording medium P side (−Z direction side) of the carriage 11. The cartridge 101 is mounted at a predetermined position from an opening opened in the + Z direction of the carriage 11, and is detachably held by the carriage 11 by a hook or the like (not shown).

  The cartridge 101 is provided with a discharge port 101 f for discharging the ink stored inside the cartridge 101. In the carriage 11, a discharge port receiving portion 11a is disposed to face the discharge port 101f when the cartridge 101 is mounted. When the cartridge 101 is mounted on the carriage 11, the discharge port 101 f and the discharge port receiving portion 11 a are disposed to face each other, and the ink in the cartridge 101 is supplied to the liquid jet head 12.

  The carriage 11 has a plurality of mounting portions corresponding to the colors of the ink in order to mount the cartridge 101 designated for each color of ink. The printer 101 mounts the cartridge 101 containing the ink of the compatible color in the designated mounting portion of the carriage 11 and ejects it to the predetermined position of the recording medium P through the liquid ejecting head 12. Color printing can be performed.

  When the ink is consumed by the printing operation and the remaining amount of ink in the cartridge 101 recorded in the control unit 30 falls below a predetermined amount, the display unit (not shown) of the printer 1 prompts the user to replace the cartridge 101. When color printing is performed, since the consumption of ink differs for each color that constitutes a color image, the cartridge 101 requiring replacement changes depending on the amount of consumption for each color. Therefore, the user (general user) needs to confirm the color of the ink required to be replaced displayed on the display unit (not shown) of the printer 1 and replace it with the cartridge 101 of the corresponding color.

  When replacing the cartridge 101, first, the color of the ink of the cartridge 101 that needs to be replaced displayed on the display unit is grasped, and the replacement cartridge 101 in which the ink of the compatible color is stored is prepared. After removing the cartridge 101 which has consumed the ink, the cap (not shown) attached to the ink discharge port 101f of the replacement cartridge 101 is removed. Then, the cartridge 101 for replacement is carefully mounted on the mounting portion designated for each color in the carriage 11.

  Here, if the cartridge 101 containing ink of a color different from the designated color is incorrectly attached to the designated attachment portion of the carriage 11, the color of the ink ejected from the liquid ejection head 12, and the control Since the color of the ink instructed from the unit 30 does not match, the printing color of the image such as a photo changes and normal color printing can not be performed. Therefore, when mounting the cartridge 101 on the carriage 11, the user needs to accurately determine the color of the ink stored in the cartridge 101.

  In addition, since the mounting direction of the cartridge 101 with respect to the carriage 11 is designated, when mounting the cartridge 101 in the carriage 11, the mounting direction (the −Y direction side and the + Y direction side) of the cartridge 101 may be discriminated and mistaken. It is necessary to wear it. Although described later, in the present embodiment, the mounting direction of the cartridge 101 with respect to the carriage 11 can be easily determined by the recess 101c and the projection 101d provided on one end side (the -Y direction side) of the upper surface 101a of the cartridge 101. Is possible.

It has -Y side surface located in the Y direction side. Furthermore, a slope is formed between the bottom surface 101b and the -Y side surface to facilitate mounting of the cartridge 101 on the carriage 11 (see FIG. 1B).

  On the bottom surface 101b of the cartridge 101, a discharge port 101f opened in the -Z direction is disposed. The discharge port 101 f is disposed to face the discharge port receiving portion 11 a (see FIG. 1B) of the carriage 11 and has a function of discharging the ink stored in the cartridge 101.

  The cartridge 101 has a recess 101 c provided so as to be recessed from the one end side (−Y direction side) of the top surface 101 a to the bottom surface 101 b side (−Z direction side). The cartridge 101 is connected to the recess 101c, and has a protrusion 101d that protrudes outward (the -Y direction side) along the Y-axis direction, which is the extension direction of the upper surface 101a. The recess 101 c and the protrusion 101 d constitute a part of + X side surface and −X side surface which intersect with the upper surface 101 a and face each other. The protrusion 101 d is provided with one shaft member 101 e along the X-axis direction intersecting the Y-axis direction.

  The recess 101 c and the protrusion 101 d are provided on one end side (−Y direction side) of the upper surface 101 a of the cartridge 101, so the user can mount the cartridge 101 on the carriage 11 in the mounting direction (−Y direction side and + Y direction side). And can be easily determined.

  Further, since the concave portion 101c, the projecting portion 101d, and the shaft member 101e are provided on one end side of the upper surface 101a of the cartridge 101, when filling the cartridge 101 with the ink in the factory for manufacturing the cartridge 101, the jig 101 can be held in a stable state.

  Hereinafter, a method of injecting ink as a liquid into the cartridge 101 as a liquid container will be described with reference to FIG. 1K. FIG. 1K is a view showing the posture of the liquid container at the time of injecting the liquid. FIG. 1K shows the cartridge 101 disposed on the flat plate 50 in a state in which the vertical direction (+ Z direction and −Z direction) is reversed. The ink can be filled into the cartridge 101 by injecting the ink from the discharge port 101 f provided on the bottom surface 101 b of the cartridge 101.

  When the ink is injected into the cartridge 101, as shown in FIG. 1K, the cartridge 101 is disposed on the flat plate 50 with the upper surface 101a facing downward so that the discharge port 101f faces upward. The recess 101 c and the protrusion 101 d provided on the upper surface 101 a of the cartridge 101 are also disposed on the flat plate 50 side. For example, by using a jig 52 having an L-shaped tip, the shaft member 101e provided on the protrusion 101d is held so as to be pressed. Then, the nozzle 54 of the injector for injecting the ink is inserted into the discharge port 101 f to inject the ink into the cartridge 101.

  By pressing the shaft member 101e with the jig 52, the movement of the cartridge 101 in the + Y direction shown in FIG. 1K and the not-shown −X direction and + X direction is restricted. In addition, movement of one end side (protruding portion 101d) of the cartridge 101 in the -Z direction is restricted. Thus, the cartridge 101 can be held on the flat plate 50 in a stable state, while suppressing the movement, wobble or falling of the cartridge 101 on the flat plate 50.

  Further, since the recess 101c is provided in such a manner as to be recessed from the top surface 101a to the bottom surface 101b in contact with the protrusion 101d, the tip of the jig 52 can be visually recognized from the + X side surface and -X side surface of the cartridge 101 in the recess 101c. Therefore, it can be confirmed that the shaft member 101e is reliably pressed by the jig 52. As a result, the cartridge 101 can be held in a stable state, and the ink can be injected into the cartridge 101 from the discharge port 101 f.

  As shown in FIGS. 1D, 1F, 1H, and 1J, a circuit board 101g is provided on the sloped portion between the bottom surface 101b of the cartridge 101 and the -Y side surface. The circuit board 101g is provided with a plurality of terminals and a storage device (not shown).
