Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a keyboard type input device, and more particularly to an input device that displays the number of keystrokes in an input device that requires work management based on the number of keystrokes.

Various input/output devices are used in electronic computer systems, and among them, many devices that use keyboards for input, such as character display devices, are used in terminal devices. However, these devices that require keystrokes have the risk of causing fire to the operator's fingers. Therefore, a method has been adopted in which the conventional key-typing operator is given a set working time and rest period. However, even if the working time is specified, the number of keystrokes during the specified time varies depending on individual differences, and due to the difference in the amount of data generated at that time, the actual number of keystrokes cannot be controlled, and the intended preventive measure against osteoporosis cannot be achieved. There was a problem.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a keyboard type input device that can display the number of keystrokes and perform uniform labor management. To briefly explain the present invention, the present invention has a function to select whether or not to display the number of keys pressed on the keyboard, and displays the number of pressed keys every moment when the display is possible, and when the required number of pressed keys is reached regardless of whether the display is possible or not. It is characterized by displaying the required number of keystrokes.

Preferred specific examples for carrying out the present invention will be described in detail below with reference to the drawings. The figure is a block diagram of an embodiment of the keyboard type input device of the present invention, in which 1 is a counter circuit, 2 is a step circuit, 3 is a required value setting circuit, 4 is a comparison circuit, 5 is a not-OR circuit, 6 and 7 are registers, and 8 is a display circuit. The key press signal is input to a counter circuit 1, and the counter circuit 1 is further provided with an increment circuit 2, which increments by +1 for each key press signal. The value of counter circuit 1 is input to comparison circuit 4. On the other hand, a required value is also input to the comparison circuit 4 from a required value setting circuit 4 that can set a required value. Comparison circuit 4 outputs input permission signal A, and inputs input permission signal A to register 7 via not-OR circuit 5 and directly to register 6. A signal B is applied to one input terminal of the not-OR circuit 5 for controlling whether or not to display the constantly changing value of the counter circuit 1. register 6
In response to the input permission signal when the required value and the value of the counter 1 are equal, the value of the required value setting circuit 3 is input and the value is output to the display device 8. On the other hand, when the counter value of the counter circuit 1 is inputted to the register 7 every moment, and when the counter value of the not-OR circuit 5 is smaller than the required value and the signal B which is displayed every moment is inputted, the register 7 is inputted every moment and the display device 8
Output to. Therefore, when the above conditions are satisfied, the register 7 inputs the counter value to the display device 8 and displays it. A reset signal C is applied to the counter circuit 1. Of course, this reset signal C may be automatically reset by the output of the display circuit 8. To explain the operation, first, a reset signal is applied to the counter circuit 1, and the required number of keystrokes to prevent the operator from getting a safety fire is set in the required value setting circuit 3. Of course, this setting can be done once and left as is, and the operator only needs to send a reset signal. When the operator starts keystrokes, the counter circuit 1 adds and integrates each keystroke, and the value is input to the comparator circuit 4 and compared with the required number of keystrokes on one side. When the counter value becomes equal to the required number of keystrokes, the comparator circuit 4 outputs an input permission signal of, for example, "1" to the register 6. Therefore, the register 6 will display the required number of keystrokes on the display device 8. This display is therefore displayed when the operator has hit the required number of keys. Furthermore, the comparator circuit 4 outputs "0" when the counter value is smaller than the required number of keystrokes, and "1" when they are equal, but when displaying every moment, signal A is "0" and signal B is "0". ”
, the not-OR circuit 5 outputs the permission signal “1”.
is output to register 7, and no input permission signal is output under other conditions. Therefore, when the counter value is small and the condition is to be displayed every moment, the register 7 displays the counter value every moment on the display device 8. That is, the counter value that changes every moment is continuously displayed, and when the required number of keystrokes is reached, the required number of keystrokes is displayed from the register 6.

As is clear from the above description, the present invention provides a keystroke display system that displays the number of keystrokes and enables uniform labor management. If the present invention is applied to an input device using a keyboard, it will be extremely advantageous in terms of management.
