Japanese Patent JP2001215554
Kind Code:
A
Abstract:

To provide a shutter for a digital camera, which is capable of regulating the aperture of a small aperture by shutter vanes and is adequate for cost reduction, downsizing and electric power saving.

A rotor 3 made of a permanent magnet rotates by a prescribed angle, in correspondence to the energization direction to a coil 6 and activates the shutter vanes 15 and 16 by a drive pin 3b. The shutter vanes 15 and 16 are respectively formed so that a semicircular pin 13c and pin 13b of a regulating member 13 can be pressed. Even if the coil 6 is not energized, the fully open state and closed state of the shutter vanes 15 and 16 are maintained by the attraction force acted between iron pins 8 and 9 by the magnetic force of the rotor 3, and the regulating state of the small aperture is maintained by the attraction force acting, in the closing activation direction and the energizing force of a spring 14 energizing the regulating member 13. The regulating member 13 is mode to be energized in either direction, depending on which side of the segment connecting a shaft 1f and a spring hooking part 1g the position of its pin 13a is located.
