Abstract

PURPOSE:To reduce the size of a shutter by dividing part of parallel link arms which support shutter blades and open and close these and disposing this in a dead space. CONSTITUTION:Five sheets or the like of shutter blades 2-6 are supported by freely turnable parallel link arms 17, 18, 19 which open and close these. The arm 18 is supported to a base plate 1 provided with an aperture 1a by means of a fulcrum shaft 18a. On the other hand, the arm 18 is substantially bisected and is supported to the base plate by the fulcrum shaft 19a of the arm 19 divided therefrom. With this constitution, it is possible to dispose the arm 19 in the dead space of the base plate and to reduce the size of the entire part of the focal plane shutter. In addition, the degree of freedom of its design is large.
