Description

[Detailed description of the invention] (a) Technical field of the invention This invention relates to an input device that inputs information using a keyboard, and in particular to a keyboard-type input device that can easily manage the cumulative number of keys pressed on the keyboard. It is.

(b) Background of the Technology Keyboard input devices are used to input information into computers. With this keyboard-type input device, the operator inputs data by hitting the keys with his or her fingers, so there is a danger that the operator's fingers may become exposed to fire.
There was a request to accurately manage the number of keystrokes.

(c) Conventional technology and problems However, in the past, the actual number of keystrokes was estimated by managing the operator's work time.
There was a problem that there was a difference in the actual number of keystrokes depending on the efficiency of individual keystrokes, and that complete labor measures were not taken.

(d) Purpose of the invention The purpose of this invention is to provide an input device that records the number of actual keystrokes based on the conventional situation as described above.

(e) Structure of the device To put it simply, this device uses an I/D device as an input device.
The device is characterized in that it is provided with a card device, and further includes a counter circuit for counting the number of keystrokes and an arithmetic circuit for calculating the cumulative number of keystrokes, and records the cumulative number on the ID card.

(f) Example of implementation of the invention An example of implementation of this invention will be explained in detail using the following figures. The figure is a block diagram showing an embodiment of the keyboard type input device of this invention, in which 1 is a keyboard, 2 is a keyboard input device, and 2 is a keyboard.
is an input device, 3 is an I/D card device, 4 is an I/D
card, 21 is a decoder, 22 is a strobe signal detection circuit, 23 is an AND circuit, 24 is a counter,
25 and 27 are registers, and 26 is an adder circuit.

The keyboard 1 sends out character information and a Stroop signal in response to pressing of a character key. Then, at the start or end of a job, for example, a LOG on/LOG off signal is sent out. These signals are input to the input device 2. What is the LOG on and LOG off signal? Decoder 21
is input. The decoder 21 decodes these signals and sets the output terminals A and B to logical values "1" and "0" respectively when the LOG is on, and sets the output terminals A and B to "0" and "1" respectively when the LOG is off. shall be. A Strope signal generated by a keystroke is detected by a Strope signal detection circuit 22 every time a key is pressed, and is input to an AND circuit 23 together with the output terminal A of the decoder 21. Therefore, the output of the AND circuit 23 becomes "1" every time the key is pressed after LOG ON is instructed. That is, the output of the AND circuit 23 becomes "1" every time a valid key is pressed, increments the counter 24, and stores the value in the register 27. On the other hand, an I/D card in which the operator's name, number of keystrokes, etc. are registered is inserted into the I/D card device. By this insertion, registers 25 and 27 and counter 24 are reset. When the operator inserts the ID card to start keystrokes for LOG ON, registers 25 and 27 are reset, and the number of keystrokes from the start of work to the end of work is stored in register 27. In the register 25, the number of keystrokes recorded on the I/D card so far is read by the I/D card device 3 and stored. When the work is completed and the LOG off signal is input to the decoder 21, B
The terminal becomes "1" and the A terminal becomes "0", and the counter 24 does not increment even if the key is pressed thereafter. "1" on the other B terminal side operates the adder circuit 26, which adds the values of the registers 25 and 27, that is, performs a cumulative total, and outputs the cumulative number.
This cumulative output is recorded on the I/D card 4 by the I/D card device 3. Therefore, the number of keystrokes for each worker is recorded in the I/D card 4, and this can be read out and displayed or printed if necessary.

(g) Effects of the invention According to the invention as described above, the number of keystrokes by the operator is recorded on the ID card, which provides many advantages in managing the number of keystrokes.
