Abstract

PURPOSE:To execute the display satisfactorily by a simple operation, by displaying a basic character and code from the first light pen input information device in the first-half part of a fly-back time, and displaying a sentence, a pattern, etc. from the second light pen input information device in the latter-half part. CONSTITUTION:When a fly-back line signal of a scanning signal is detected by a detector 5, a pulse from a clock pulse generator 7 is outputted in the first half of a fly-back time from a circuit 6, signals outputted through X and Y direction counters 8, 9 are inputted to the first light pen input information device 13, and a basic character and a code by a light pen 14 are inputted. Also, when an information card 35 has been placed on the second light pen input information device 17, if a detecting piece 36 of the card 35 contacts with a detector 18, a detecting signal is outputted from the detector 18. In this way, the information of a sentence, a pattern, etc. of the card 35 is sent out to a CRT4 from the detector 5 in the latter half of the fly-back time.
