PURPOSE:To miniaturize a motor, to make a camera compact and to reduce the number of components by rotating forwardly and backwardly a motor in a different direction after a restraining member is engaged with a lens moving member and taking the opening/closing actions of a sector. CONSTITUTION:The S-pole is generated on the pole part 9a of a stator 9 and the N-pole is generated on the pole part 9b, by the energizing of a coil L and a rotor 10 is turned counterclockwise. A rotor actuating lever 11 force-fitted and fixed into the rotor 10 is turned counterclockwise by the turn, as well, so that a lens restraining member 12 engaged with the rotor actuating lever pin 11a of the rotor actuating lever 11 is turned clockwise and a control circuit turns the rotor 10 of a swing motor M via the coil L of a motor driving part in response to a focusing signal outputted from an AF part and moves the rotor 10 up to a position A. In such a state, the control circuit turns the lens moving member 3 around a shutter opening 2 clockwise by a lens driving part, to engage a stepped cam 3a with a curved part 12b and hold it in the state of the position A. |
