Abstract

PURPOSE:To make the CRT capable for use as the input device as well as the output display device, by providing it with the CRT, light pen LP, and keyboard pattern generator KPG. CONSTITUTION:When the source of power supply is made on, the instructions to load the pattern of the desk calculator type keyboard, for example, for the operation based on four fundamental rules of arithmetic from KPG to refresh memory PM is sent from the CPU to KPG. The keyboard pattern is sent from KPG to RM under said instructions and is displayed on CRT. The operator inputs as desired with a light pen in the same manner as a key input of the normal keyboard type while watching the screen of CRT. The lowest line of the CTR screen is occupied by the CPU, and display part DSP for one-line components is arranged there, and the contents of an information inputted to the CPU are displayed there through the light pen. As a result, the keyboard is not required, and the device is made small-sized an simple.
