検出ス５インチ。A lens that detects the rotation limits of the lens on the infinity side and on the close side of the camera, which extends the lens by the rotation of a motor controlled by a control circuit built into the camera, and inputs the signal to the control circuit. In the movement limit detection switch, a cutout portion is provided on a rotation member that extends the lens and has first and second end surfaces corresponding to rotation limits on an infinity side and a close side of the lens; a lens drive stop piece provided on the fixed cylinder; and first and second switch contact pieces that are also provided on both sides of the lens drive stop piece and whose tips face the rotation range of the notch, As the rotating member rotates, the lens driving stop piece and the first or second end face of the notch sandwich the first or second switch contact piece, thereby moving the lens toward infinity or A 5-inch lens movement limit detection device, characterized in that it is configured to detect a movement limit on the closest side.
