PROBLEM TO BE SOLVED: To provide a shutter holding mechanism capable of reducing vibration and the like caused by reaction force of shutter blade movement and of holding a shutter unit in a stable manner.SOLUTION: A shutter holding mechanism includes; a shutter substrate 21 provided inside a camera body 1 and having a focal-plane shutter unit 2 fixedly mounted thereon; pressing means 11 that is located between the camera body and one end side of the shutter substrate to push the shutter substrate toward the other end side of the shutter substrate relative to the camera body; and damper means 13 that is located on a part of the camera body corresponding to the other end side of the shutter substrate opposite to a position where the pressing means is arranged, in a direction along a travel direction of a shutter blade of the shutter unit, to absorb movement of the shutter substrate pressed by the pressing means. The shutter substrate is arranged in the camera body such that the shutter substrate can move only in the direction along the travel direction of the shutter blade of the shutter unit.SELECTED DRAWING: Figure 3 |
