PURPOSE: To provide a cooker of high reliability that allows unmanned inspection.

CONSTITUTION: In a microcomputer-controlled cooker having a microcomputer for controlling cooking operations, the microcomputer 20 is provided with a communications means 31, an input state transmission means 33 for transmitting information about the plurality of inputs of an input circuit device 30 to the outside via the communications means 31, and a current time reception means 34 for setting the current time of a timepiece means 25 by receiving a current time signal transmitted from the outside. The microcomputer 20 is further provided with an output operation means 35 for operating the plurality of output circuit devices 14 one by one or in combinations in response to specification data transmitted from the outside. An input state inspection device 40, a reference timepiece device 41 and an output inspection device 42 are programmed in the personal computer 39 of an inspection device 36 and the communication means 31 of the microcomputer 20 is connected to the communicator 37 of the inspection device 36, to transfer numerical data between the microcomputer 20 and the inspection device 36 for automatic inspection.
