PROBLEM TO BE SOLVED: To provide a shutter fitted to a camera body part with high precision of parallelism of a slit formation side of a blade to a slit formation pixel array without reference to whether individual members constituting a curtain have an error in molding or performance error.SOLUTION: There is provided a focal plane shutter such that a bottom plate 1 comprising blades forming a slit with an electronic curtain is fitted to a bottom plate receiving part 50 having first, second pins 51, 52, the bottom plate comprising: a shaft hole 1h where a first pin is fitted rotatably; a long hole 1i in which a second pin can be loosely fitted in a rotating direction of the bottom plate; an eccentric pin 31; a position adjustment hole 33 which can change in relative position to the bottom plate, and abut on a second pin on both side faces by fitting the second pin fitted loosely in the long hole; an adjustment mechanism 30 which adjusts the relative position of the position adjustment hole 33 to the bottom plate by slightly rotating the ground place around the shaft hole; and fixing means 40 of fixing the relative position between the position adjustment hole and the bottom plate at a position where the fitting angle of the bottom plate to the bottom plate receiving part is finely adjusted.SELECTED DRAWING: Figure 1 |
