<p>PROBLEM TO BE SOLVED: To easily and repetitively stand a laid-down casing of an operation board by locking the front part or the rear side face of the casing covering the operation board which is erected on a base and also supports a stand shaft. SOLUTION: A round rod made of a spring steel, etc., is bent into a U shape, and both tips of the rod are bent inward in parallel to a connection shaft part 4. Thus the rotary shaft parts 2 and 3 are formed for a stand shaft 1. A pair of shaft holes, are formed on the back of a casing A of an operation board, and the rotary shaft parts 2 and 3 are put into the shaft holes and rotatively pivoted. Then the casing A which is erected on a base 6 and supports the shaft 1 is locked by a lock part 7 formed on the base 6. In such a constitution, the casing A which is kept laid down while the input operation board is not used can be easily and repetitively stood.</p> |
