摘要： The present invention provides a shutter apparatus and a drive method for the same, the shutter apparatus having functions of both a shutter apparatus for an image interception and a shutter apparatus for an aperture adjustment and being space-saving and low in costs. Within an illumination casing are provided first and second shading plates 212 and 215, first and second cammed gear 224 and 227 having a cam groove 225 and 228 respectively for driving the first shading plate 212 and the second shading plate 215 respectively. A cam shape is structured such that the rotation of a DC motor 235 (one drive source) enables the first and second shading plates 212 and 215 to drive independently. Thus, arbitrarily operating the functions of both the shutter apparatus for the image interception and the shutter apparatus for the aperture adjustment by the DC motor 235 (one shared drive source) is possible.

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.

摘要： A camera with lens barrier apparatus in which the lens barrier apparatus is driven by a motor that is also used to drive another mechanical element in the camera. The motor is switched between the lens barrier apparatus and the mechanical element by the movement of a lens barrel. In this arrangement, the driving of the lens barrier apparatus and the mechanical element are controlled in accordance with the output of a single sensor, for example an encoder.The driving of the lens barrier apparatus is controlled such that the barrier will not close unless the lens barrel is at the housed position and such that if the lens barrier does not open, the lens barrel will not move. The driving is further controlled such that if the lens barrier apparatus does not move to its intended state, the drive is reversed prior to again attempting to drive to the intended state.The lens barrier apparatus is mechanically arranged such that barrier blades are nonresiliently driven during a portion of the closing or opening operation and are resiliently driven during the remainder of the closing or opening operation.
