PURPOSE:To reduce the load of process, by transferring both the sending figure request and the sender information to a central control device when a read instruction is received from the central control device. CONSTITUTION:The sending figure information is sent to an interface circuit INT to the sending figure request given from a central control device CC. Thus the circuit INT designates an address corresponding to the sender that gave a sending figure request to a figure state memory circuit MEM1 and then writes the sending figure information. On the other hand, a register circuit RC designates an address corresponding to the number of sender that is transferred and erases the corresponding sending figure request. A discriminating circuit DTC sends the figure information sent from the device CC to a sender, and the circuit INT transfer both the sending figure request given from a monitor circuit SUV and the sender information to the device CC. |
