ABSTRACT:
A camera shutter device having a charging rotation axis mounted to the camera body rather than mounted to the shutter base. A charging force of a shutter charging mechanism is transmitted through a linkage lever rotatably supported by to charging rotation axis on the shutter base to a shutter mechanism, wherein leading blades and trailing blades are charged by the charging force. The charging rotation axis is positioned outside an operation area of the leading and trailing blades and is connected to a camera body so as to be unable to move in any plane directions of the shutter base, whereby the charging force is not directly applied to the shutter base but to the camera body so that the shutter base is prevented from being deformed.
