PURPOSE: To improve an operating property, by ANDing an instruction execution completion signal and a repetition instructing signal from a controller of an information processor having a console panel which is capable of operating the information processing manually, and starting the execution of an instruction once again.

CONSTITUTION: When an operator starts execution of store instruction by operating manually a console panel, a Key is turned on, and ground for starting is provided to an OR circuit G1. A controller CPU fetches an address to be stored, through a bus from a storage device MEM, stores it in an ADRREG (address register), fetches a store data and stores it in a DATREG (data register) temporarily. When the store is completed, the CPU sends a completion signal to an AND circuit G2. On the other hand, when a repetition instructing signal is applied to other terminal of the circuit G2, the circuit G2 provides an output, and restarts the CPU through the OR circuit G1. In this way, since the function of the device is executed repeatedly, the operating property is elevated.
