Abstract
PURPOSE: To simplify programming by generating a write clock pulse on a transparent program sheet by an opaque material and then by forming a sequence time chart of a screening adhesive tape.
CONSTITUTION: On transparent program sheet 1, write clock pulses and R/W lines for write and read commands are printed in screening ink. Data write scale 4 is printed in screening ink and synchronizes with the clock pulses. On this scale, screening adhesive tapes are stuck so as to form time charts in parallel. Since the result can be seen on this sheet, data programming and its modification can easily be attained. This sheet is inserted into a sequence control unit and then, the contents are written to the memory by the sheet reader composed of light emitting element 25 and photo detecting element 27. Photoelectric switching circuits corresponding to R/W lines keeps in sending write signals from the insertion of sheet 1 until its extraction and then sends a real signal on the extraction, thereby becoming ready for a read.
