摘要： A focal plane shutter adapted for use in a single lens reflex camera and having front and rear curtains with respective charge control gears to be operated in engagement with each other during the winding process. At the terminal end of one cycle of winding operation, these gears are released from positive connection with a film winding mechanism, while the front and rear curtains are held in their cocked positions by separate latches in at least a time interval between a moment at which the diaphragm starts to move and a moment at which the mirror flips out of way to actuate release of the front curtain, thereby an electromagnetic release control for the rear curtain latch is prevented from being disturbed as by a shock which would be otherwise exerted on the rear curtain latch at the start of movement of the front curtain.

摘要： In a focal plane shutter having two curtains which unwind from shafts after being released, the shaft controls a master gear, causing a keying pin on the latter to activate braking action on the curtain at a time interval near the terminal end of running-down movement of the curtain, as a pair of heavy expanding frictional shoes are driven to rotate at accelerated speeds and pressed against the internal surface of a fixed drum by a centrifugal force. During the shutter cocking operation, the key is taken out of connection with the brake so that the driving torque of the film winding shaft is correspondingly decreased.

摘要： An image recording system in which an object image is caused to be formed on a solid state image transducer such as CCD each time a release is actuated, and the image signal stored on said image transducer is recorded as a video signal, thus a single frame image is recorded for each release. By controlling the storing operation of the image signal and the like, the exposure level for the image signal is adjusted to make it possible always to record and reproduce the image with regard to an optimum exposure state.

摘要： A digital camera with five automatic exposure modes is provided with corresponding individual cards upon selective insertion into the camera to effect the operation of either or both of the shutter and diaphragm in accordance with the digital output of a computer through logic selection circuits as the mode information on the inserted card is read into a binary coded decimal counter controlling operation of the logic circuits. When the card is absent from the camera, a first controlling push button for sequential display of the modes is rendered effective to pass a pulse train to the counter so that upon release of the button, the current mode displayed can be set. The card further includes information relating to the determination of whether or not to give a sound warning signal which occurs, in one embodiment, when the film nears the terminal end of footage. In another embodiment, the buzzer is utilized to assist in releasing not only a first but also an additional three buttons for setting exposure factors and a number of film frames available just after a desired symbol or digital value appears in the display as they are sequentially presented.

摘要： A camera performing a film winding action with an electric wind-up mechanism and producing a winding completion signal upon completion of each film winding action. A counter and a discriminating circuit are reset by a back cover closing signal produced when a back cover of the camera is closed to have the counter count the winding completion signals. When both the winding completion signal and an output signal of the discriminating circuit representative of the initial state thereof are obtained, an electromagnetic release mechanism is automatically actuated to carry out an exposure action. Upon completion of the exposure action, the film winding action of the electric wind-up mechanism is performed. When the counter has counted a predetermined count value, the discriminating circuit is inverted by a count output of the counter to automatically render the electromagnetic release mechanism inoperative.

摘要： A motor drive unit adapted for use with a camera having a motorized shutter speed adjusting device. When a continuous series of frame exposures are to be made at a predetermined frame frequency, the set value of shutter time in the camera is made to be compared with the longest possible shutter time dependent upon that frame frequency by a comparator provided in the motor drive unit. When the actual shutter time value exceeds the longest possible one, the motorized shutter speed adjusting device is actuated, causing the shutter time value to change itself to the longest possible value.
