摘要： The camera shutter unit of the present invention comprises a diaphragm blade arranged to be capable of moving between a stopping-down position wherein an aperture is stopped down, and an evacuating position wherein the aperture is opened. A shutter blade is arranged to be capable of moving between an opening position, wherein the aperture is opened, and a closing position, wherein the aperture is closed. A dive-control mechanism is provided for drive-controlling the shutter blade and the diaphragm blade. The drive-control mechanism has a single electromagnetic drive source, a spring for restricting movement of the shutter blade toward the closing position when the diaphragm blade is positioned in the stopping-down position, and for releasing its restriction by a predetermined or more drive force generated by the electromagnetic drive source, and a control means for controlling the electromagnetic drive source. The control means, upon stopping down, controls to move the shutter blade to the closing position in advance and next move in reverse the shutter blade by a predetermined amount, thereby positioning the diaphragm blade in the stopping-down position. Accordingly, the unit can be of a small size and low in cost, and the bouncing of diaphragm blade can be prevented.

摘要： In a camera shutter apparatus, a shutter blade is arranged movably In an open direction and a close direction relative to a lens aperture for opening and closing the lens aperture from a home position to perform an exposure operation. A setting member is provided to operate when setting the lens aperture at a predetermined diameter for holding the shutter blade to a stop position corresponding to the predetermined diameter with a biasing force. A drive source is provided for generating a driving force necessary for moving the shutter blade. A controller is provided to operate when moving the shutter blade from the home position to the stop position so as to set the lens aperture and then moving the shutter blade in the close direction for an exposure operation. The controller controls the drive source to regulate a magnitude of the driving force sufficient for activating the shutter blade from the home position and smaller than the biasing force of the setting member to hold the shutter blade at the stop position in abutment against the setting member.
