Abstract

By using a focal plane shutter having one set of shutter blades as a shielding member of an image pick-up element, it is possible to miniaturize the shutter compared to a focal plane shutter having two sets of blades. This enables the operation to be simplified, and also saves space. Furthermore, in an electronic camera having this focal plane shutter, because the shooting lens side of the image pick-up element that is disposed in the main camera body can be disposed protruding into the shutter unit, the length of the main camera body in the direction of the optical path of the shooting lens can be reduced, and it is possible to form the main camera body small compared to a conventional main camera body.
