摘要： A shutter device includes a movable shading module and a movement control module configured to control movement of the movable shading module. The movable shading module includes a shading unit, a driving unit and a signal measuring unit. The shading unit includes two blades, and the movement control module is configured to generate a control signal. The driving unit is configured to receive the control signal and drive the two blades. The signal measuring unit is configured to measure an operating status of the blades feed it back to the movement control module in real time. The movement control module is configured to update the control signal based on the fed back operating status. This shutter device can overcome the problems of low exposure dose accuracy and light leaks arising from the use of existing shutters and provide various accurately-controlled exposure doses suitable for different applications.

摘要： A shutter base plate is formed with a first shaft parallel to an optical axis of a photographic light flux, and a blade lever rotates about the first shaft to drive a first blade and a second blade. A drive lever rotates about the first shaft to drive the blade lever. A second cam gear rotates about a second shaft formed on the shutter base plate in parallel to the first shaft to charge a mirror drive spring. A first cam gear rotates about a third shaft formed on the shutter base plate in parallel to the first shaft to switch between a state in which the blade lever is held so that the first blade and the second blade close the aperture and a state in which holding of the blade lever is released.

摘要： An image capturing apparatus includes a shutter spring which urges a shutter drive member for driving shutter blades, a shutter charge unit which is used to charge the shutter spring, and is switched between a fixed state in which a charge operation of the shutter spring is complete, and the shutter drive member is fixed and a released state, and a drive unit which drives the shutter charge unit. When a second determination unit determines that a switching ready state of a mirror from a mirror-down state to a mirror-up state is set when a first determination unit determines that a charge operation of the shutter spring is complete, the drive unit is controlled to drive the shutter charge unit to the released state without latch the shutter charge unit in the fixed state after the charge operation of the shutter spring is complete.

摘要： An exposure control device for use with a camera provided with two objective lenses having different focal length which are selectively used includes two exposure control elements which are disposed in front of and facing to the two objective lenses, respectively, and simultaneously driven by a drive means. One of the lights passed through the respective exposure control elements which is selected by optical path changing means is allowed to reach a film. The exposure control elements are used either diaphragms which usually allow the admittance of light into the objective lenses or shutters which are usually forced to be in positions where intercepting the optical paths of the objective lenses.

摘要： A shutter is rotatably mounted in a housing for opening and closing a shutter aperture in the housing. The shutter is coupled to a drive unit for unidirectionally rotating the shutter with the same velocity profile to open and close the shutter aperture during each exposure period. This drive unit includes a drive motor and a control circuit having a source of position and velocity reference data and a feedback control loop configurable for either position or velocity control of the shutter as determined by a control command.
