PURPOSE:To obtain an inexpensive device with a simple constitution by providing a driving force transmission mechanism which is arranged between a driving member and a lens and transmits the driving force from the driving member to the lens part and switching the transmission route of this driving force to select the lens moving direction. CONSTITUTION:When a lens L is moved in the (y) direction, an electromagnetic actuator 43 is turned on, that is, its solenoid is excited. Since the operation rod 46 of the electromagnetic actuator 43 is operated backward to rotate a brake arm 41 toward a carriage shaft 11 at this time, the other abutting piece 45 of the brake arm 41 is abutted against a part of the carriage shaft 11 to damp the carriage shaft 11 in its axial direction. Since a lens carriage 12 is fixed to the carriage shaft 11 in this state, a belt 36 is moved in the (y) direction on the lens carriage 12 when the belt 36 is moved by the rotation of a driving motor 25, and the lens L is moved in the (y) direction in accordance with this movement. |
