Abstract
A control apparatus for a copier capable of transferring data from a non-volatile memory thereof to a computer or similar external data processing equipment, allowing the data in the memory to be rewritten from the outside, and in the event of replacement of a control board loaded with the memory allowing the data to be transferred from the memory of the old control board to a non-volatile memory of a new control board with accuracy and reliability. Data are transferred from the old control board to a new control board via serial communication controllers which are provided on the individual control boards. A communication unit is also provided on the control board so that the content of the non-volatile memory may be transferred to the external data processing equipment or rewritten by the latter.
