PROBLEM TO BE SOLVED: To facilitate attachment/detachment work of a power unit 50 relative to a casing 20 while preventing a fraud to the power unit 50. SOLUTION: The power unit 50 is provided with a connecting terminal part 51 in its upper surface. The power unit 50 is mounted on a bottom plate 21 with its back face abutting on a back plate 24 and its one side abutting on one side plate 23. A power supply holder 100 is provided with a fixing part 110 to be fixed to the casing 20, a cover part 120 covering a connecting terminal part 51 from the upper part, and a locking part 130 locking the power unit 50. The power supply holder 100 is so formed as to fix the fixing part 110 to the casing 2 with its lower surface abutting on the upper surface of the power unit 50. The locking part 130 prevents the power unit 50 from moving at least frontward and in the direction of a non-abutment side plate. COPYRIGHT: (C)2005,JPO&NCIPI
