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 display device for displaying the time of a bulb photographing operation is arranged so that a counter for counting the clock pulses starts to operate when the bulb photographing mode is set in the camera and the release operation of the camera is started. A decoder incorporated in the camera decodes the content of the counter and a display instrument displays the output of the decoder in such a manner that the photographer can visually recognize the bulb photographing operation time. Several embodiments of the circuitry for controlling the nature of the display, including timing charts therefor, are set forth.

摘要： A motor drive camera incorporates a motor drive device and a power source for the device and is adapted to mount a detachable auxiliary power source device to supply additional electric power to the motor drive device so as to raise the film winding up speed. The motor drive device includes a timer device whose operation is initiated at the same time as the initiation of power to the motor drive device and which effects the stop of power to the motor after the passage of a predetermined time. The operating time of the timer device is adapted to be changed in order to prevent the film from being damaged when mounting the auxiliary power source device to the camera.

摘要： A camera having a control system for coordinating the release actuator and electronic shutter with either one of a battery and an electric generator incorporated therein. As the battery has lost electrical energy, the removal of the battery from the camera enables the coordinating system to restrict the manual setting of an exposure time within faster limits and to supply electrical power from the generator to at least that portion of the automatic exposure control circuit which contributes to manual exposure control during the second stroke of the shutter release button, provided that the necessary mechanical energy for driving the generator was created and stored on suitable means during the preceding cycle of film winding operation.

摘要： The disclose circuit energizes a magnetic winding of a shutter actuating device. A constant voltage circuit is connected across the magnetic winding, or between the power supply terminal of the magnetic winding and a basic potential to ensure that the response of the armature of the actuating device to the output of a timing circuit is stabilized despite variation in the voltage of an electrical power source. This produces the advantage of substantially improving the accuracy of exposure control, because the closing operation of the shutter is controlled through movement of the armature.

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： 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.
