Abstract

PURPOSE:To transmit and receive data between a main body side and a transmittal side through a common memory by forcibly releasing a common bus using request after a certain lapse of time in order for a main body operation processing part so as not to occupy a common memory for a time to cause a trouble to a transmission process with a main body arithmetic processing part. CONSTITUTION:In case of a transmission, a common bus 2-1 using request is outputted from a main body operation processing part 1 to a signal line 1-1. Thus, an one-shot timer 5 is actuated, a signal line 5-1 is activated and a set signal is provided to an FF7 by an AND with the bus using request 1-1. When the FF7 does not receive a reset signal by a using request signal 3-2 at a transmission side, an output Q goes to H and a using approval signal of the common bus 2-1 is outputted to 7-1. The processing part 1 receives the signal and writes data in the memory into a common memory with the bus 2-1. Next, when a transmission-reception operation processing part 3 outputs the common bus request 3-2, the signal is made into the resetting input of the FF7, when the using request from the processing part 1 is not set, the pocessing part 3 makes an output Q as the common bus approval signal of 3-3, the processing part 3 receives it and the using approval of the common bus 2-1 is outputted to 3-3.
