    摘要: A flash photographic exposure control system for a camera having an electrically timed shutter is provided with an additional electronic or mechanical timing device in combination with an electronic changeover switch responsive to attainment of the threshold level of the flash unit associated therewith. This is done to switch the camera from an automatic daylight exposure range to an automatic flash exposure range in which a particular timed interval suited for flash photography is made by the timing device which is brought into cooperation with the shutter operating means when the changeover switch is actuated, while the intrinsic timing device for the shutter being cut off from the control means for the shutter.

    摘要: A voltage detecting means is provided in a flash lamp firing circuit for detecting the attainment of the voltage of a storage capacitor to a satisfactory lamp firing voltage level to assure that a photographic camera associated with the flash lighting unit operates in a flash exposure range switched from a daylight exposure range only when a sufficient voltage is available to fire the lamp at the time of striking of the lamp. In one embodiment, the detecting means comprises two transistorized circuits having output terminals one of which is connected to the gate lead of a SCR in a discharge circuit of the lamp, and another output terminal which is arranged to be connectable to a light-emitting diode of the camera and therefrom connected to the gate lead of an electronic change-over switch for selection of the operating ranges of the camera, the light-emitting diode being arranged to be visible from the outside of the camera so that the operator is immediately aware if the storage capacitor voltage has attained the satisfactory firing level.

    摘要: In the disclosed motor driven camera, a motor drive is removably attached to a camera body and includes a grip which is fitted to the camera body. Separate switches respond to separate operating members on the upper surface of the grip and the side face of the drive device. A terminal on the camera body provides a signal to a control device and a second terminal on the motor drive connects electrically to the first terminal when the motor drive is attached to the camera body so as to furnish a signal, corresponding to the switching action of either of the switches, to the control circuit. The operational positions of the first and second release switches facilitate camera release in either the horizontal or vertical positions of the camera.

    摘要: A film advance error detection system for synchronizing the operation of shutter cocking and film winding mechanisms with a motor drive unit therefor. This system utilizes three transducers positioned adjacent the sprocket wheel, film perforations and rewinding spindle to pick up signals whose frequencies are related to their speeds. By processing the signals in combination with an output signal of a phase difference compensator, it is made possible to provide, in a selective manner, a display representative of the film advane error and reeling end in the winding and rewinding operations along with the automatic stoppage of rotation of the motor.

    摘要: An electric motor drive device for film winding. The conventional motor drive devices include a type in which the motor is normally kept in an operative state under a no load condition and the rotation force thereof is transmitted to a film winding mechanism during film winding. Another type actuates the motor during film winding. In the former arrangement, keeping the motor in an operative state requires less power consumption for actuating the motor and also eliminates the problem of delayed start. However, since the motor receives power even under a no load condition, a high voltage is impressed on the motor to cause vibration, beat, or the like even under a no load condition, thus causing camera vibration resulting in a blurred picture. In accordance with the present invention, this shortcoming of the conventional device is eliminated by differentiating control over the power supply to the motor under a no load condition from a power supply control in a film winding condition to ensure that no high voltage is impressed on the motor under a no load condition.
