摘要： A camera blade driving device for use in a camera has a base plate having an exposure aperture; a blade supported pivotably on a supporting shaft on the base plate and capable of blocking part or all of light passing through the aperture while facing the aperture; and an electromagnetic actuator for driving the blade. The electromagnetic actuator has a frame member joined to the base plate; a rotor one end of which is supported by the frame member and an opposite end of which is supported by the base plate, the rotor having a driving pin by which a driving force is exerted onto the blade and rotating within a predetermined angular range; a magnetizing coil wound onto the frame member and the base plate; and a yoke provided outside the coil substantially coaxially with the rotor. With this structure, a fastening component like a screw is not needed, the number of components can be lessened, the structure can be simplified, costs can be reduced, and the driving device can be reduced in thickness, unlike a conventional device.

摘要： A lens shutter for cameras includes two base plates in which a blade chamber is provided between them and their apertures are superposed to provide a circular exposure aperture, at least one shutter blade located in the blade chamber to perform the opening and closing operation of the exposure aperture, a first motor mounted to one of the base plates outside the blade chamber so that an output port extends to the blade chamber to cause the shutter blade to perform the opening and closing operation, a light-amount control device located in the blade chamber to perform the introducing and removing operations with respect to the exposure aperture, and a second motor mounted to one of the base plates outside the blade chamber so that an output port extends to the blade chamber to cause the light-amount control means to perform the introducing and removing operations. In this case, the light-mount control device is located so that a part thereof always overlaps the shutter blade adjacent thereto in any operating condition.

摘要： When the main power of a camera is turned on, a set member (14) is rotated from an initial position to a set position by an operation member (15) on the camera side and once stops at a midway position. At this time, a second blade group (19) retreats from an aperture (1a) and a first blade group (16) enters the aperture 1a to a position not covering an image pickup device (4), so that the aperture (1a) is opened and it is made possible to display a subject in an electronic viewfinder. When a release button is pressed, the set member (14) is rotated from the midway position to the set position and thus the aperture (1a) is covered with the first blade group (16). After this, when drive members (10, 12) are attracted to iron cores (8, 9) and the set member (14) is restored to the initial position, the drive members perform light exposure operation in order.
