Abstract: An electric dimming device used in an imaging device or a display device, and a method for driving the device. When a diaphragm adjusting control signal is changed from the current diaphragm adjusting value (±VX1) to a large value (±VY1) (that is, when the light transmittance of a positive liquid crystal is raised the light transmittance of a negative liquid crystal is lowered), a period for which the value (±VZ1) is larger than the large value (±VY1). The energy and time of this large value (±VZ1) are determined according to a preset value. Therefore, the response speed of when the light transmittance can be remarkably raised, and a rate of change of one or less field period required as the diaphragm mechanism of a video camera can be realized.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method for driving a stepping motor which can suppress the occurrence of a noise due to a motor drive and which can alleviate a load of processing to control via a microcomputer. SOLUTION: A camera unit 1 has a camera lens 10 which is lens-controlled, by the stepping motor 12 microstep-driven and a recorder 11 on a surface directed toward a subject side at photographing times. The unit 1 also has a motor control unit 13 for controlling the dividing number in the one period so that the product of the frequency of the drive signal of the motor 12 with the dividing number during one period of the signal becomes a fixed frequency for the total driving speed range of the motor. Thus, the motor 12 is driven via a motor driver 14, controlled and the sound level of the predetermined frequency signal is attenuated, for example, by a band elimination filter provided in the recorder 11.

Abstract: PROBLEM TO BE SOLVED: To provide a protector for an optical element capable of moving a barrier blade in the closing direction of an aperture during non-energization, thereby preventing the aperture from being kept open caused by vibration, external force, or the like. SOLUTION: The protector is provided with: a stator section 58 incorporating a coil and a magnetic core; a drive section 19 having a rotor part 66 incorporating a magnet 67; and a movable blade 20 moved in the direction where the aperture 15 is closed or opened. When energizing the coil, the drive section moves the movable blade 20 to a first position that the aperture is closed by the movable blade and to a second position that the movable blade is moved farther in the direction than the position where the aperture is fully opened. During the non-energization, the movable blade is moved in the closing direction by the holding torque of the drive section 19, and the range of rotation in the closing direction is made greater than the range of rotation in the opening direction with the rotated position of the rotor part 66 when the holding torque is the smallest as a reference, and also the aperture is fully opened in a third position, which is between the first and second positions and in the closing direction rather than in the position of the reference.
