Abstract

PURPOSE: To insert and extract a memory unit without destroying data written in the memory unit by providing a memory unit mount part so that the memory unit is detached after a power source is detached. CONSTITUTION: The memory unit mount part 10 is provided adjacently to a power source mount part 13. To dismount the memory unit 11 from the memory unit mount part 10, a housing 9 is turned over to make a groove part 25 face up, and the power source 14 is extracted from the power source mount part 13. A button 21 of a memory unit unlocking mechanism is pressed in and the memory unit 11 is extracted from a connector. Then, the memory unit 11 is detached from the housing 9 through the groove part 25. Therefore, the power source 14 is detached prior to the detachment of the memory unit 11, so the memory unit 11 can not be detached during program operation.
