<p>PURPOSE: To use a power source jack as a part for fitting by providing an extended unit to be mounted on the side surface of a main body by being slid, power source jack, and power source plug to be coupled with the power source jack. CONSTITUTION: An attachment 7 is fastened on a main body 1 with screws and in such a state, a plug 19 is slid by fitting rails 8 and 8 inside lock pieces 16 and 16 from a direction of an arrow A so that the guide rails 8 and 8 can be held by the lock pieces 16 and 16 of a unit 12 while housing the plug 19 in the unit 12. When the unit 12 is stopped at a certain position so that a third translucent window can be faced with a second translucent window 11, the power source plug 19 is positioned so as to be faced with an opening 10, namely, faced with a power source jack 5. Then, a lid 18 is slid to the side of a counter plane 17 for coupling this plug 19 with the jack 5 so that mounting is completed. In such a state, the slide of the unit 12 is blocked by the plug 19 and the slide of the lid 18 is blocked by the coupling power of the plug 19 and the jack 5 as well.</p> |
