Claims

[Scope of Claim for Utility Model Registration] 1. A base plate, a cover plate, and a leading shutter blade group and a rear shutter blade group provided between them with a partition plate in between, each consisting of a plurality of shutter blades. In a shutter device comprising a curtain shutter blade group, and a blade support plate provided between each of the shutter blade groups and the base plate and cover plate to prevent the shutter blades from interfering with the base plate and the cover plate. , the distance between at least one of the blade support plates and the opposing base plate or cover plate is such that the position where the shutter blade is transferred at the time of shutter charge is greater than the position where the shutter blade is transferred when the shutter travel is completed. A blade support device for a focal plane shutter, characterized in that at least one of the blade support plates is installed at an angle so that the blade becomes narrower. 2. The base plate and the cover plate are provided parallel to each other, and the distance between the inclined blade support plate and the partition plate is widened at the position where the shutter blades are transferred during shutter charging to allow the shutter blades to run smoothly. A blade support device for a focal plane shutter as claimed in claim 1 of the utility model registration.
