ABSTRACT:
A sequence control system comprising a transparent program sheet bearing a series of write clock marks and a plurality of data lines and arranged in the longitudinal direction of the sheet; a sheet reader having photo-electric switching means. The program sheet is inserted into the sequence controller from one side until it reaches a positioning index, then the sequence controller being ready for write cycle. While the sheet is pulling out from the other side, the write clock marks generate write clock pulses and then the data will be sequentially written into a memory in synchroniztion with the write clock. After the program sheet has been extracted, a read ready state is automatically established. To read the data, cycle time is determined and a start switch is turned on, then the data being delivered from outputs of the memory in synchronization with the read clock pulse.
