PURPOSE:To obtain a device whose function is expanded remarkably and easy to handle by applying automatic reproduction along with an instruction program and applying easily the reproduction apart from the said instruction program. CONSTITUTION:A control circuit 16 enables a data processing circuit 12 and an instruction storage circuit 13 and instruction data on an instruction 1a picked up through a head 4 is stored in the storage circuit 13 through the data processing circuit 12. The control circuit 16 uses a read circuit 14 to execute an read instruction, gives a count-up pulse to a read circuit 14 to allow the circuit to read the next instruction. When a stop switch 17S is operated during automatic reproduction, a flip-flop 18 in the reset state is set and since its Q output is at a low level, the count-up pulse is stopped by an AND gate 8 and not given to the read circuit 14 and the instruction is fixed at that point of time.
