Abstract

(57) [Summary] [Structure] A signal specifying the function of the foot key 2 is sent from the keyboard 1 to the key input control circuit 3 through the input signal line a6, and the key input control circuit 3 receives the signal. to set the function of foot key 2. Thereafter, the signals transmitted from the keyboard 1 or the foot keys 2 are transmitted to the key input control circuit 3 through the input signal lines a6 and b7, and the key input control circuit 3 transmits the signals from the keyboard 1 as they are. , the signal from foot key 2 is converted into a signal of the set function and transmitted. The signal is sent to the key code conversion circuit 4 through the input signal line 8, and the key code conversion circuit 4 converts the signal into a code signal to be used in the main body 5 and sends it to the key code signal line 9. The data is sent to the main body 5 through the main body 5, and the data is processed in the main body 5. [Effects] According to the above, the function can be achieved simply by stepping on the foot key instead of the awkward manual input operation, and the input operation of programs, data, etc. is facilitated.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is used when inputting programs or data into computers, etc. Concerning keyboard circuits.

0002

[Conventional technology]

Keys traditionally used to enter programs or data into computers, etc. - The board circuit will be explained with reference to the drawings.

0003 FIG. 2 is a block diagram of a conventional keyboard circuit.

0004 In Figure 2, the conventional keyboard circuit is used to manually input programs or data. Keyboard 1 is used to input signals during operation, and input signals input from keyboard 1 are input to main unit 5. and a key code conversion circuit 4 that converts the code into a usable code and outputs it to the main body 5. Each part is connected by input signal line d10 and key code signal line 9. Ru. Then, the main body 5 receives the code signal from the key/code conversion circuit 5 and receives the data. data is being processed.

[0005]

[Problem that the idea aims to solve]

As mentioned above, conventional keyboard circuits do not allow input of programs or data. When using simple keystrokes or difficult keystrokes (pressing two keys at the same time, etc.) Do not perform all operations that are difficult to use (such as keys in difficult-to-press positions) by hand. Therefore, if it becomes a major hindrance to the input operation of programs or data, etc. There is a drawback.

[0006] The purpose of this invention is to control some of the functions of the keyboard using a key input control circuit. By using it as a key, the above disadvantages can be solved and the manual input operation can be avoided. The wrong operation can be performed simply by pressing the foot key with the foot. Keyboard with foot keys for easy input of programs or data, etc. The objective is to provide a code circuit.

[0007]

[Means to solve the problem]

The keyboard circuit with foot keys of this invention allows for manual operation of programs or data. Keyboard input by key input and foot key input by foot operation. , a key input control circuit that specifies foot key functions based on instructions from the keyboard. and the program or data is input to the keypad under the control of the key input control circuit. A key that converts the signal input from the code or foot key mentioned above into a code and outputs it. It has a code conversion circuit.

[0008]

【Example】

Next, embodiments of the present invention will be described with reference to the drawings.

[0009] Figure 1 is a block diagram of a keyboard circuit with foot keys according to an embodiment of the present invention. Ru.

0010 In FIG. 1, the foot key keyboard circuit of this embodiment has a signal input section. Keyboard 1, foot key 2, and key input that specifies the function of foot key 2. a force control circuit 3 and a key/code conversion circuit 4 that converts an input signal into a code and outputs it. and a main body 5, input signal lines a (for keyboard input) 6, b (for footboard input), (for keyboard or foot key input) 7, c (for keyboard or foot key input) 8, Each part is connected by a code signal line 9.

[0011] A signal specifying the function of foot key 2 from keyboard 1 is sent to input signal line a6. The signal is sent to the key input control circuit 3 through the key input control circuit 3, which receives the signal. to set the function of foot key 2, and then set keyboard 1 and foot key 2 after setting. It is used to input programs, data, etc. to the key code conversion circuit 4.

0012 The operation sequence after setting the function of foot key 2 is as follows. .

[0013] Input signals sent from keyboard 1 or foot key 2 to signal lines a6 and b7 It is transmitted to the key input control circuit 3 through. The key input control circuit 3 includes a keyboard The signal from foot key 1 will be sent as is, and the signal from foot key 2 will be sent as is. convert it into a functional signal and transmit it. The transmitted signal is sent to the key through the input signal line c8. - Sent to code conversion circuit 4. The key code conversion circuit 4 converts the received signal into It is converted into a code signal used by the main body 5 and transmitted. And the code signal is The key code is sent through the signal line 9, received by the main body 5, and the main body 5 receives this code. Process the signal as data.

[0014]

[Effect of the idea]

As explained above, the keyboard circuit with foot keys of the present invention allows key input By using a control circuit to make the foot keys use some of the functions of the keyboard, By pressing the foot keys with your foot, you can easily perform manual operations that are difficult to use. It is now possible to simply perform the function, and input operations such as programs or data can be performed easily. This has the effect of making it easier.
