Abstract: A focal plane shutter for a camera which is suitable for miniaturization and arranged to prevent wear debris from entering into a blade chamber via a base plate hole. Wall portions (1j and 1k) are formed protruding towards the blade chamber side surface from edges of the elongated holes (1b and 1c) provided in a base plate (1).

Abstract: A focal-plane shutter for cameras is constructed so that the second blade group is placed in a blade chamber on the shutter base plate side and the first blade group is placed in a blade chamber on the auxiliary base plate side. The auxiliary base plate is placed on the image sensor side in a camera and secures projecting members, each having a spherical convex portion whose surface is palladium-plated. In the first blade group, five blades are pivotally supported by two arms, and immediately before, at least, a joint shank for pivotally supporting a slit-forming blade is moved inside the aperture for exposure of the auxiliary base plate during operation and reaches a position corresponding to the edge of the aperture, the arm strikes on the projecting member and is shifted to the object side so that the head of the joint shank does not abut against the edge of the aperture. Consequently, it is avoidable that the head of the joint shank abuts against the edge of the aperture to produce wear dust.

Abstract: A support structure of a focal plane shutter in a camera reduces the effects of impacts or vibrations accompanying opening and closing movements of a shutter such that the impacts or vibrations do not reach a camera body. The support structure includes a shutter baseplate which is mounted and floats with respect to the camera body. The shutter baseplate supports a number of light barrier members which move in a travel direction to expose photographic film. The shutter baseplate is movable in the travel direction by a pair of retaining members. The position of the shutter baseplate is set by a position setting member which is fixed to the shutter baseplate and is retained by a vibration absorbing member disposed in the camera body. Buffer members are disposed between upper and lower ends of the shutter baseplate and the camera body such that impacts or vibrations which accompany the opening and closing operation of the shutter do not reach the camera body via the shutter baseplate.

Abstract: Guide rails for positioning a film are formed on a shutter block. The guide rails project through an opening in a thin back plate of a camera body to regulate the position of a film drawn from a film cartridge chamber into a spool chamber. A frame aperture formed in the shutter block regulates the exposable area of a frame of film. The shutter block is fixable to a box-shaped mirror housing, which is then fixed to the camera body and a supporting plate.
