Abstract

(57) [Abstract] [Purpose] The present invention is a keyboard switch in which a plurality of keys having unique functions are arranged in a matrix, and each key allows a unique function to be input by another function. In addition, the operation can be easily performed only by the sensory movement of the finger without recognizing the position and type of each key. According to the present invention, a plurality of keys each having a unique function are configured so that a function input different from the unique function can be made by continuous key operation, so that the number of keys can be remarkably reduced. The continuous key operation does not require visual confirmation and can be easily performed by a so-called blind touch feeling operation.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention is a keyboard switch for remote control such as channel conversion, in which a plurality of keys are arranged in a matrix and the key surface is flat (membrane type). This is related to the switch method that can be input.

[0002]

[Prior Art]

 Generally, in this type of keyboard switch, a plurality of keys are arranged in a matrix in an orderly manner except for a special case. Each of the keys thus arranged functions independently, and if, for example, keys 1 to 9 are present, each of them operates independently and can operate 9 kinds of switches. .

[0003]

[Problems to be solved by the device]

 The keyboard switch in the above-mentioned conventional example functions only for the number of keys, and when it is desired to add more functions, it is necessary to increase the number of keys correspondingly and make a design change in the hard side. Instead, each key must be operated by pushing or touching it while visually confirming it. Therefore, in the conventional example, since keys having individual functions are required, the number of keys tends to increase. Therefore, except for the point of adding many functions while reducing the number of keys and the unique function of each key, There is a problem to be solved in that it can be operated easily without checking the key position.

[0004]

[Means for Solving the Problems]

 As a concrete means for solving the above-mentioned problems of the conventional example, the present invention is a keyboard switch in which a plurality of keys having unique functions are arranged in a matrix, and the keys are continuously operated by continuously operating the keys. The present invention provides a keyboard switch method configured so that a function input different from a unique function can be input, and the continuous key operation is performed in a touch order or a movement path of a finger, and only in a touch order or a finger movement. The trajectory is approximated and different function inputs are set by a switch method in which the ON sequence of the key matrix is patterned to correspond to continuous key operation.

[0005]

[Action]

 In the keyboard switch, in addition to each key having its own function, it is possible to input different functions by continuous key operation within a certain time, so that the number of keys can be significantly reduced, and continuous key operation is possible. Does not require visual confirmation, and can be easily performed by a so-called blind touch feeling operation.

【Example】

 Next, the present invention will be described in more detail with reference to the illustrated embodiment. Reference numeral 10 is a membrane type keyboard, which has touch keys having, for example, 1 to 9 independent functions.

This keyboard 10 is, for example, one in which conductors 14 and 15 are printed on upper and lower film bases 12 and 13, respectively, and the surfaces of the conductors 14 and 15 are faced to each other, and a plurality of them are arranged between them. The dot spacers 16 are disposed so as to intervene.

An arrangement of the touch keys 1 to 9, that is, an example of a 3 × 3 matrix is configured as shown in FIG. That is, the conductors 14 and 15 printed on the upper and lower film bases 12 and 13 are composed of three rows of conductor pieces 14a, 14b, 14c, 15a, 15b and 15c, each having a lead terminal. The touch keys 1 to 9 are formed so as to face each other so as to cross each other through the plurality of dot spacers 16. The lower film base 13 can be replaced with a glass material, a printed circuit board or the like.

In the above-mentioned embodiment, the upper and lower film bases having conductors are crossed to form a matrix, but in the other example shown in FIG. 4, the printed board 17 is used as the lower base material, A predetermined electrode portion can be formed on the printed board. That is, the printed wirings 18 for forming predetermined electrode portions are provided on the printed board 17 so that the touch keys 1 to 9 are arranged in the same manner as in the above-described embodiment.

In this case, the electrode portion 19 formed by the printed wiring 18 is formed in a shape corresponding to the touch keys 1 to 9 such that, for example, the counter electrode is comb-shaped. Then, the upper film base 12 is arranged by sandwiching the film-shaped spacers 21 having the holes 20 at the positions corresponding to the comb-teeth-shaped electrode portions 19 in a sandwich shape.

The film base 12 used here does not need to be provided with a lead terminal, and it suffices if the conductor 14 on the entire back surface or the conductor pieces 14 a to 14 c corresponding to the electrode portion 19 are present. In short, it suffices that the touching electrode comes into contact with the comb-teeth-shaped electrode portion 19 and becomes electrically conductive with the counter electrode via the conductor or the conductor piece.

In the membrane type keyboard switch configured as described above, the touch keys 1 to 9 are capable of inputting a unique function corresponding to a channel such as a television or a video, as in the conventional example. In the present invention, the ON sequence based on the continuous key operation of the key matrix of the touch keys 1 to 9 within a certain time is patterned, and another function input function is added according to the pattern of the ON sequence. There is a purpose.

That is, in the ON sequence of the key matrix, as shown in FIG. 5 in the arrangement of the touch keys 1 to 9, for example, the continuous key operation in the horizontal arrangement turns the power ON / OFF, and the vertical arrangement in the volume knob. By adjusting the brightness of the image to a large or small amount, adjusting the brightness to the right or to the left, and adjusting the tone to the left or to the right, 8 types of continuous key operations are patterned.

The patterning in the continuous key operation of the touch key is performed by, for example, setting a pattern in which the touch keys 4, 5, 6 are moved from left to right with the finger touching the key surface to power ON. On the contrary, set the pattern to move from right to left to power OFF to enable function input. In this case, the same pattern is applied to the arrangement of 1, 2, 3 and the arrangement of 7, 8, 9. In short, the operator does not visually observe the key surface but moves the finger touching the key surface laterally from left to right or from right to left to perform continuous key operation, that is, a blind touch feeling. It is to be able to turn on / off the power supply by the operation function.

Also in the vertical direction and the diagonal direction, the same as above, if the finger touched on the key surface is moved based on the set ON sequence pattern to perform continuous key operation, Similarly to the above, each function of the set pattern can be selectively input by the feeling operation by the blind touch.

In this case, each of the touch keys 1 to 9 has an independent unique function input function, and the independent unique function input and the function input based on the patterned ON sequence are provided. In order to determine and output, for example, a pattern of continuous key operation may be registered in a built-in microcomputer (hereinafter referred to as a microcomputer), and determination may be performed based on the pattern.

The determination by the microcomputer will be described with reference to the processing program shown in FIG. 6. For example, when the touch key 4 is touched with a finger in step, there is a continuous key operation input within a fixed time in step ( If there is no continuous key operation input, it is determined as NO by checking whether YES or NO (NO), and the unique function input of the individual key is turned ON in step.

If there is a continuous key operation input within a certain time in the step, it is output to the step side, and the input signal of the continuous key operation matches the set pattern in the step (YES. ) Or not (NO), and if it does not match the set pattern, error processing is performed in step.

When the input signal in step 4 matches the set pattern, it is output to the step side, and in that step, the function output registered in the input pattern of the continuous key operation is performed. If the signal is an input pattern of continuous key operation of 4, 5 and 6, the function for turning on the power is output. These judgments and operations are the same for all touch keys 1-9, and also for the patterned function output of continuous key operation.

In this way, by patterning the ON sequence of the key matrix according to the movement trajectory of the finger, in addition to the functions assigned to the original key matrix, each key is blind-touched without being visually or visually recognized. The feeling operation function can be added additionally.

In the above description, it has been explained that eight kinds of feeling operation functions by blind touch can be added by the touch keys 1 to 9, but the number of matrices is increased and only the moving direction is set in the microcomputer. Not only that, it is also possible to recognize a complicated movement pattern such as the movement amount and the movement speed, so that more filling operation functions can be added. Furthermore, in order to give flexibility to the movement of the finger in the continuous key operation, even if the continuous key operation of 1, 2, 6 or 1, 2,- It is designed to be approximated by a soft approximation.

[0022]

As described above, the keyboard switch system according to the present invention is a keyboard switch in which a plurality of keys having unique functions are arranged in a matrix, and continuous key operation of the keys is performed. By this, it is configured so that a function input different from the unique function can be input, and a new function input can be made by the continuous key operation, so that the number of keys can be increased or the hardware can be changed. It has an excellent effect that another function can be easily added without adding.

In addition, the continuous key operation is performed according to the touch order or the movement locus of the finger, and the touch order or the movement locus of the finger is approximated, and different function input settings are made. The ON sequence of the key matrix is set in a pattern corresponding to continuous key operation, and it can be easily operated by blind touch by so-called general movement of the finger without visually observing the key operation. It has an excellent effect.
