    摘要: The disclosed camera is provided with an automatic focus adjusting device for automatically adjusting the focus of an objective lens. A timer circuit, adapted to be actuated in synchronism with the automatic focusing device initiating focus adjustment of the objective lens, sets a predetermined time and inhibits the actuation of a shutter release device for the predetermined time. In a preferred embodiment, the shutter release actuation is controlled in accordance with the logic condition of a focus adjustment completion signal obtained from the automatic focus adjusting device and a time count completion signal produced when the predetermined time has elapsed. In another embodiment of the present invention, a battery voltage detecting circuit prevents shutter release when the voltage of the battery energizing the camera is below a predetermined level.

    摘要: A distance detecting device comprising radiation projecting means for projecting a radiation beam; radiation sensing means which is disposed away from the radiation projecting means with a given length and is arranged to receive a reflected radiation beam coming from an object whose distance is to be detected as the radiation beam is projected from the projecting means; and movable means for relatively varying the incident condition of the projected radiation beam onto the sensing means. The distance to the object is found either by the position of the movable means or by the amount of displacement thereof which occurs at a time point at which the sensing means optimally receive the reflected radiation beam coming from the object in the process of relatively varying the incident condition of the projected radiation beam onto the sensing means. In the incident condition varying process, the output signal of the sensing means and a delayed signal which is obtained by delaying the output signal a predetermined period of time are compared with each other to detect a time point at which the output signal of the sensing means has reached its peak level and, accordingly, to detect when the sensing means optimally receive the reflected radiation beam coming from the object.

    摘要: A focal plane shutter unit for a camera has a dimension-stable framework which has a rear wall member provided with an exposure aperture and with a film guide channel defining a path of the film behind the exposure aperture and which has a front surface to which a support structure having means for receiving and holding a lens mount is fixedly secured so that a predetermined spatial relationship between the objective lens and the film plane is established with dimension-stability, though the internal and external camera housing sections are made from a dimension-unstable material such as plastic. The framework is further adapted to carry front and rear shutter curtains with respective drive means, front curtain actuating means, rear curtain actuating means, and shutter cocking means coupled to the film wind mechanism of the camera.

    摘要: The present invention relates to an exposure meter circuit of a camera with a matching network for a flash device with which camera auxiliary light photography can be carried out the flash device presents a detecting output terminal of a detecting network for detecting the level of the stored energy of an energy storing means provided in the flash circuit of the flash device, a voltage supply terminal for supplying the operation voltage to the detecting network and a synchronizing terminal for triggering the flash device. With this camera, daylight photographing can also be carried out without a flash device. The exposure meter circuit is characterized in that in the exposure meter circuit a current source is included for the exposure meter. A first switching means is connected with one electrode of the current source. Grounding of the current source occurs in functional connection with the switching of the flashlight photographing over to the daylight photographing. A second switching means is connected in the exposure meter circuit and switches off the light receiving means, where in the case of the flash photographing, the voltage is given to the supply terminal from the current source for the exposure meter by means of said first switching means so as to operate the detecting network. In the case of the daylight photographing, the light receiving means is connected in the exposure meter circuit by means of the first and the second switching means so as to bring the detecting network out of operation by grounding the current source.

    摘要: A temperature compensating device for devices comprising semiconductors. The temperature compensating device comprises a temperature compensating circuit, such as a circuit including a diode, and a current control circuit which adjusts the quantity of the electric current flowing through the temperature compensating circuit. The temperature characteristic of the temperature compensating circuit is mutually compensatory with that of the output of the device comprising semiconductors. When the temperature characteristic of the output of said temperature compensating circuit differs from that of the output of such semiconductor device, the current control circuit causes a current which corresponds to the difference between the temperature coefficient of the compensating circuit and that of the semiconductor device to flow through the temperature compensating circuit, so that satisfactory temperature compensation can be accomplished.
