PURPOSE:To enable the easy removal of a stopper from a groove with light force by removing the stopper from the groove in the initial period of moving an interlocking member which is moved in an optical axis direction then moving an optical element holder in the optical axis direction. CONSTITUTION:When a rack gear 11 with a stopper 5 held inserted in a V- groove 8a moves rightward, the stopper 5 is forced upward by the press contact of its slope 5a with the slope 9a of a stopper actuating member 9, and a roll 7 is removed from the groove 8a. When the ascending of the stopper 5 stops, a lens holder 1 is pressed by the stopper 5 to the member 9, and is moved together with a guide rack gear 11 toward the right. When the holder 1 moves to the position of a V-grooves 8c, a motor 12 is stopped by the detection signal thereof. The stopper 5 descends while pushing back the member 9 in the optical axis direction and the roll 7 enters the groove 8c. The stopper is thus removed from the groove with light force. |
