Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an input device, and more specifically, to a device for inputting a large amount of information such as kanji characters using 10 to 60 decimal keys such as a kana keyboard or an alphabet keyboard.

Conventionally, with this type of input device that inputs a large amount of information such as kanji using a decimal keyboard, there is a certain relationship between the input information and the characters on the keys, for example, when inputting a kanji, A method is used in which a code corresponding to a kanji is input by pressing a key corresponding to the reading of the kanji and converting the combination of codes corresponding to the pressed key.

However, in this method, there is no direct relationship between the code generated by keystrokes and the code of the information such as kanji to be input, so the input device requires a special keyboard, or the input code and kanji are not directly related to each other. A significant drawback was that a very large fixed storage device had to be provided to convert the code.

Therefore, an object of the present invention is to realize a means for realizing a device for inputting a large amount of information such as kanji characters with a simple device using a small number of keyboards. In order to achieve the above object, the present invention includes a code that divides a code consisting of multiple bits divided into information to be input such as kanji characters, and includes a code that includes the divided code (subcode) at a predetermined bit position. The input device is simplified by pressing a key that outputs a code and synthesizing the keys to directly obtain the code made up of the plurality of bits. The present invention will be explained in detail below using the drawings. FIG. 1 is a bit configuration diagram in an embodiment for explaining the principle of the present invention.

In this embodiment, it is assumed that the Kanji code is implemented using 14 bits. Consider dividing this into 5-bit, 5-bit, and 4-bit subcodes, C1 and C2 respectively.
, C3. On the other hand, it is assumed that the above keyboard outputs an 8-bit code corresponding to any key contact point.

In the embodiment of the present invention, the keyboard is pressed three times to input the 14-bit information.

That is, in the keystroke shown in FIG. 1, a key whose pre-specified bit matches C1 is pressed. Similarly, C2
,C3. Generally, there are multiple keys corresponding to 5 bits of information of C1, for example, but 8
Since only 5 of the bits are selected and the remaining 3 bits are ignored, it is only necessary to press any one of the plurality of bits (kana or alphabet). FIG. 2 shows the configuration of an embodiment of the present invention. In inputting in this method, first, the control circuit 2 is activated by pressing a function key. The circuit counts the number of subsequent key presses. First, in response to the first keystroke, gate circuit 3
5 bits required for 1 are gated and set in register 5 via switch 4. Next, the code corresponding to the second keystroke is stored in register 6, and the code corresponding to the third keystroke is stored in register 7.
Set to . This causes registers 5, 6, and 7 to contain 14
The kanji code for the bit will be set.

Note that the gate circuit does not need to be placed between the keyboard 1 and the switch 4, but may be placed between the switch and the register. Further, even if it is not necessarily gated, it has the same effect as a gate as long as the output of the 8-bit signal is not connected to a register. Further, as a modification within the scope of the present invention, a small capacity fixed storage circuit is provided between the keyboard 1 and all or any of the registers 5, 6, and 7,
It is conceivable to set a code different from the keyboard output in the register.

However, since this memory circuit can also be considered as a keyboard output, this does not depart from the gist of the present invention. It goes without saying that a person with ordinary skill can make various modifications, such as using a program-controlled circuit as the control circuit 2.

Further, when a serial/parallel signal is required as a Kanji code, one or two registers 5, 6, and 7 may be used in a time-division manner. As described above, in the present invention, 1) the necessary kanji code can be directly obtained without requiring a special keyboard and 2) without providing a large-scale fixed recording device for converting input codes and kanji codes. It is extremely effective as a kanji input device or as an auxiliary means for a kanji input device.

Furthermore, it can be used not only for kanji but also for inputting multi-bit codes.
