Japanese Patent JP2011137990
Kind Code:
A
Abstract:

To provide a shutter driving device, along with a camera, capable of improving durability.

When a front curtain driving lever 141 is stopped, an abutting part 141g is allowed to abut on a shock absorbing member 113, a shock is absorbed by the shock absorbing member 113. Thus, the shock, given when the front curtain driving lever 141 is stopped quickly, can be made to be small, and load on a sequence shutter driving unit 100 and a light shielding curtain device 400 is reduced, thereby the durability is improved, and shock sound can be made to be low. Thus, bound and shake in a front-and-rear direction in a front curtain light shielding blade group 411 can be suppressed, the image quality of an image obtained by imaging is prevented from degradation, and also failure such as wear can be prevented.
