Abstract

PURPOSE:To increase the processing speed, by transmitting a communication request signal to the Nth external device, transmitting a communication prediction signal to the (N+1)th external device and corresponding with the (N+ 1)th external device, just after the end of correspondence with the Nth external device. CONSTITUTION:A communication controller transmits a communication request signal to the Nth external device and a communication prediction signal tR to the (N+1)th external device. The signal tR is outputted during a communication processing time tN of the Nth external device. When a prediction signal is detected, no task processing is started and the input of the communication request signal is waited, and just after the correspondence with the Nth external device is finished, correspondence is made with the (N+1)th external device.
