PURPOSE:To simplify the operation of a power source by omitting individual complicated power source operation by switching the operation of a sub processor to either a standby state or an operating state in interlocking with the operation of a main processor when an information signal is processed by the main processor and the sub processor formed separately. CONSTITUTION:This processor is an information signal processor performs processing of a prescribed information signal SA by using the main processor integrally with the sub processor both of which are formed separately. The sub processor 3 is provided with an information signal transmission part 12 which performs the spatial transmission of the information signal SA with the main processor inbetween, an information signal processing part 13 which performs processing of the information signal, and a control part 20 which controls the whole operation. The control part 20 holds the whole operation in a standby state when the main processor is held in the standby state based on the operation of the information transmission part 12, and starts the whole operation when the main processor is erected in the operating state. Thereby, it is possible to omit the individual start operation of the power source. |
