<p>PROBLEM TO BE SOLVED: To operate a switch arranged in the inside of main body casing of an electronic equipment interlocked with switch operation of a cap. SOLUTION: The cap 4 opening/closing by rotational motion is fitted on the main body casing 2, and an open/close angle control arm 8 having a reverse open preventing rib 8a on its tip is formed on the cap 4, and a detection switch 13 is mounted on a circuit board 12 in the inside of the main body casing 2 answering to the tip part of the open/close angle control arm 8. Then, an operation cam part 8b operating the operation piece of the detection switch 13 is formed integrally on the tip of the open/close angle control arm 8, that is, the reverse open preventing rib 8a, and a first tilt cam surface 8b1 brought slidably into contact with and pressing the operation piece of the detection switch 13 when the cap 4 is opened and a second tilt cam surface 8b, brought slidably into contact with and pressing it when closed are formed on the operation cam part 8b by changing the tilt directions.</p> |
