PURPOSE:To simplify verification and allow an operator to select a playback method optionally by confirming and checking playback contents only by calling memory contents. CONSTITUTION:When an automatic mode is specified in four arithmetic operations, a flip-flop (F) F1 is set, and when a playback key (PBK) is pressed, FPB is set; and their outputs are operated on the basis of a flow chart while an AND gate A1 is opened. It is judged wheher the FPB is set or not by the operation of the PBK before a series of operations are completed, and the FPB is reset when the PBK is operated again, thereby stopping subsequent operations. When the PBK is operated again, the FPB is set. Consequently, a playback function is stopped temporarily. When all operations are completed, this is judged in an address m12 and automatic playback operation is completed.
