PROBLEM TO BE SOLVED: To easily change the position of a front switch detecting an advance limit position while watching the switch even when a movable board is covered with the front edge part of a cover by installing the holder of the switch detecting the position of an ejection rod. SOLUTION: An ejection device is composed of the ejection rod 12 inserted freely forward/backward movably into the movable board 11, a switch actuation member 15 erected at the base end part of the ejection rod 12, and a pair of position detecting switches 19 and 20 arranged alternately in the front/rear on both sides of the member 15. The holders 21 and 22 of the switches are installed side-by-side from the upper surface part onto the back of the movable board 11 with the moving space of the member 15 left. The front switch 19 detecting the advance limit position of the ejection rod is fitted horizontally slidably to one holder 21. The rear switch 20 detecting the retreat limit position is fixed to the holder 22, and the switches are installed on the movable board. COPYRIGHT: (C)2004,JPO
