Abstract
PURPOSE: To prevent the occurrence of erroneous printing and malfunction by adding constitution which detects errors when data is transmitted between a master and a slave and which retransmits data when there is the errors.
CONSTITUTION: First and second error detection circuits 3 and 4 are added to a master central processing unit 1 and a slave central processing unit 2. The master unit 1 and the slave unit 2 transmit data through a data transmission line 6. Transmitted data are encoded in codes obtained by adding check bits for error detection to conventional data. When the error detection circuit 3 or the error detection circuit 4 detects the error of data, a retransmission control part 5 receives error detection signals from the error detection circuit 3, instructs the slave unit 2 of retransmission, receives the error detection signals from the error detection circuit 4 and instructs the master unit 1 of retransmission. Thus, the occurrence of erroneous printing and malfunction can be prevented.
