Abstract
In a single-lens reflex camera, the rotation center of a lever used for driving a shutter device is arranged rearward of a shutter device with respect to an optical axis, and the lever end (point of action) is arranged in front of the shutter device with respect to the optical axis. Thereby, compactness of the camera body can be realized.
