Abstract
A shutter and a photographing apparatus are provided. The shutter includes: a shutter base including an exposure opening; a shutter mechanism including a blade assembly and a synchronizer ring for driving the blade assembly, the synchronizer ring being movable between a first position and a second position, and the exposure opening being open when the synchronizer ring is in the first position and closed when the synchronizer ring is in the second position; and a braking member for decelerating the shutter mechanism. In the shutter and the photographing apparatus according to the present disclosure, the shutter mechanism may be buffered when the blade assembly closes the exposure opening of a camera, so as to prevent the shutter mechanism from being damaged.
Claims18
A shutter, comprising:
- a shutter base including an exposure opening;
- a shutter mechanism including a blade assembly and a synchronizer ring to drive the blade assembly, wherein
- the synchronizer ring is movable between a first position and a second position, and
- the exposure opening is open when the synchronizer ring is in the first position and closed when the synchronizer ring is in the second position;
- and a braking member to decelerate the shutter mechanism, wherein
- the braking member includes a braking ring to decelerate the shutter mechanism by limiting a position of the synchronizer ring,
- the braking ring includes a plurality of limiting portions arranged in a circumferential direction of the braking ring and distributed on the braking ring at equal intervals.
A photographing apparatus, comprising:
- a shutter including:
- a shutter base including an exposure opening,
- a shutter mechanism including a blade assembly and a synchronizer ring to drive the blade assembly, wherein
- the synchronizer ring is movable between a first position and a second position, and
- the exposure opening is open when the synchronizer ring is in the first position and closed when the synchronizer ring is in the second position, and
- a braking member to decelerate the shutter mechanism, wherein
- the braking member includes a braking ring to decelerate the shutter mechanism by limiting a position of the synchronizer ring,
- the braking ring includes a plurality of limiting portions arranged in a circumferential direction of the braking ring and distributed on the braking ring at equal intervals.
A shutter, comprising:
- a shutter base including an exposure opening;
- a shutter mechanism including a blade assembly and a synchronizer ring to drive the blade assembly, wherein
- the synchronizer ring is movable between a first position and a second position, and
- the exposure opening is open when the synchronizer ring is in the first position and closed when the synchronizer ring is in the second position;
- and a braking member to decelerate the shutter mechanism, wherein
- the braking member includes at least one friction member to decelerate the shutter mechanism by friction, and
- the at least one friction members includes a plurality of friction members, and the plural friction members and a plurality of limiting slots are staggered along the circumferential direction of the braking ring.
