Japanese Patent JP2003029319
Kind Code:
A
Abstract:

To allows a kick type shutter device to obtain a stable shutter speed with a small individual body difference.

A cam hole 78e formed in a shutter driving lever 78 and a connecting pin 76 formed on a sector lever 76 engage each other. The cam hole 78e is composes of a driving cam hole and a cam hole for a stopper. A kick arm 71b kicks a claw part 76a of the sector lever 76 in response to releasing operation and the sector lever 76 rotates clockwise against a spring 77. The connecting pin 76d pushes an edge of the driving cam hole to rotate the shutter driving lever 78. After shutter blades 84 and 85 are opened to full open an opening 78 for exposure, the connecting pin 76d strikes the edge of the cam hole 78a for the stopper to rebound, thereby stopping the sector spring 76 from further rotating forward. The sector lever 76 rotates counterclockwise by being energized with a spring 77 and is drawn back to its initial position.
