Abstract
Abstract The normal program storing portion stores a normal program containing a control procedure of the program rewriting apparatus and a spare rewriting program. In a first period, the control device overwrites the received normal and spare rewriting programs on the normal program storing portion. In a second period different from the first period, the control device copies the spare rewriting program overwritten on the normal program storing portion to the rewriting program storing portion in accordance with the overwritten normal program.
