摘要：
A program operating apparatus is provided, which is capable of rewriting control programs for a plurality of CPUs without using any exclusive external apparatuses, thereby achieving a simplified and efficient rewrite operation. A control program stored in a ROM of a master CPU that controls the basic operation of the entire apparatus is transferred to a slave CPU and then written to an internal ROM of the slave CPU which controls the operations of functional units of the apparatus. The transfer of the control program is carried out when the mode of the apparatus is switched to a write control mode.
