Attempts have been made to input data using switches or transparent electrode methods.In some cases, there are also methods of inputting data using expensive input devices such as image sensors.

るを得なかった。It was necessary to check the input results again on a display separate from the input operating device such as a CRT, and it was complicated to have to move the operator's viewpoint from the desk to the CRT screen each time input was made. . Is this a touch panel switch on the CRT screen? With the added system, there is some improvement, but the touch panel switch has a poor resolution of about 1 quadrature ht number a, and the CRT's cathode ray tube has a large curvature and is thick, making input work difficult. There were problems in making the process go smoothly. In addition, with the above-mentioned input card and stem, the display and input functions are separate devices, making the system as a whole expensive.
