DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard device that is capable of displaying flexible key tops composed of dot matrix. The present invention relates to a keyboard device that controls the display of a key display section, making it possible to ensure operability.

[Prior Art] As a prior art related to a keyboard device capable of displaying flexible key tops, for example, Japanese Patent Laid-Open No. 62-23
A technique described in Japanese Patent No. 3821 and the like is known. This conventional technology focuses on the fact that the size of characters that can be visually recognized is smaller than the key size required for an operator to enter the key, and stores multiple key top contents within the key frame of one key. By displaying the information, the number of keys in the entire keyboard device can be reduced, and the keyboard can be made smaller. And the display of the key top of each key is as follows.
Flexible display is possible.

At the initial stage of operation, the contents of a plurality of key tops are displayed within one key frame. The operator selects the key on which the desired key top contents are displayed, but at this point, the contents of a plurality of key tops are assigned to one key.

[Problems to be Solved by the Invention] The above-mentioned prior art displays a plurality of visually recognizable key top contents within a key frame of a size necessary for an operator to manually operate a key. The problem is that the operator must perform two key operations in order to select the key to be used. Furthermore, in the prior art, the positional relationship of the contents of each key top with respect to the keyboard device is such that a plurality of key top contents are displayed within one key frame. Since the position changes greatly between the state and the state where the content of one key top is displayed within one key frame, when performing input by blind touch, the operator has to It is necessary to memorize the positions of two keys,
There is a problem in that it is difficult to perform blind touch input.

That is, the above-mentioned conventional technology is a useful technology for downsizing the keyboard device, but it requires two keys due to the human power required for one key.
Since the keys must be operated in multiple locations, there are problems in that the operability is not good and the speed at which the keys are manually operated is slow.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to solve the problem that, as in the case of the prior art, the size of characters that can be visually recognized is smaller than the size of the keys required for key input. The object of the present invention is to provide a keyboard device that improves operability, allows manual key operation with a single key operation, and is miniaturized.

[Means for Solving the Problems] Generally, the size of a keyboard device is determined by the size of each key and the number of keys. Further, the size of each individual key is determined to a certain extent depending on the thickness of a person's fingers in order to avoid interference with adjacent keys when performing input. Therefore, the size of the key should be large enough to ensure that only the desired key is large enough for the operator to manually press the key.

According to the present invention, the objective is to make the key size large enough for the operator to operate only the key on which the operator inputs or is about to input, and for other keys, the contents of the key top can be visually checked. This is achieved by providing a function to change the size of the keys so that they can be reduced to a recognizable size.

The display control section 3 performs control to display the key top content 9 and the key frame 8 to be displayed on the key display section 4, and when the sensor section 1 is not detecting anything, the contents 9 of the key tops and the key frame 8 that are to be displayed on the key display section 4 are displayed. The contents 9 of the key tops and the key frame 8 are displayed. In this state, the size of the key frame 8 indicating the size of one key is smaller than the size required for the operator to press the key manually, and the contents 9 of the key top are also large enough to be visually recognizable. , and each key frame 9 has the same size.

When an operator's finger approaches the key display unit 4 and the finger position detected by the sensor control unit 2 is input to the display control unit 3, the display control unit 3 determines which key frame the finger position is closest to. It is controlled so that the size of the key necessary for the operator to press the key manually can be secured in the key frame 8 closest to the finger position. In other words, the 1 display control section 3
The identified key frame 8 and the surrounding key frames 8 are enlarged at a preset ratio, and conversely, the key frame 8 located away from the finger position is reduced to display the keys displayed on the key display section 4. Display is performed by changing the size of the key frame 8 so as not to reduce the number of keys. The size of the key frame and the size of the contents 9 of the key top are not large enough for keys that are far from the finger position, but the keys are unrelated to the key force, so the overall size of the keys is It does not affect the operation of the keyboard device.

As described above, the display control unit 3 includes a ROM that stores calculation logic for enlarging or reducing the key frame 8 as a finger approaches to perform a key operation, or a key frame pattern for setting a key frame. It also has a storage means for retaining the contents of the key top contents 9, a function to display the key top contents 9 at the center of the display of the key frame 8, and a function to display the key top contents 9 in the center of the display of the key frame 8. It has a function to enlarge or reduce the font size of the top content 9.

In actual operation of the keyboard device, especially when performing a blind touch, multiple fingers touch the touch panel 5.
It is used close enough to the object that it cannot be detected. In this case, in the above embodiment, if the key frame setting method using calculation is used, it is also possible to control the key frame 8 that is close to each finger to enlarge the key frame 8 necessary for the operation. , the operator can perform operations without feeling uncomfortable. In particular, in the case of blind touch operation, even if the contents 9 on the key tops are so small that the characters cannot be visually recognized.

The display on the key frame 8 is changed by detecting whether the optical path of the sensor is blocked or not, but in the present invention, since the finger is hot, the display on the key display section 4 is changed. It is also possible to provide a thermal or infrared sensor on the surface to detect the finger position. In this case, the distance between the finger and the key display section 4 can be detected based on the output intensity of the sensor, so the key frame 8
Although the present invention has been described as a keyboard device having a grid pattern, the present invention can also be applied to a keyboard device in which one row of keys and each row of keys are spaced by half keys, such as in the JIS layout.
