    摘要: The present invention relates to a camera so designed that the aperture preset mechanism as well as the aperture adjusting mechanism at the side of the camera body are operative by means of the first urging mechanism provided in the lens barrel. The aperture adjusting mechanism is operated by means of the release operation of the camera so as to close the aperture preset mechanism down to a certain determined aperture value. Between the aperture adjusting mechanism and the aperture preset mechanism an intermediary member and the second urging mechanism are provided. By means of operating the focus depth confirmation member, the aperture preset mechanism is closed down to a certain determined aperture value through the intermediary member. The camera is brought into the state ready for taking a picture by means of the second urging mechanism upon releasing the focus depth confirmation operation.

    摘要: The present invention relates to an exposure information setting device for a camera having a digital control system in which the aperture value of the lens is applied to the exposure amount control circuit as digital information by means of the aperture value setting mechanism. The device is so designed that the first comb tooth shaped conductor pattern and the second comb tooth shaped conductor pattern are arranged in parallel with each other in such a manner that a phase difference takes place between them. A pair of series of pulses are obtained by making the contact in functional engagement with the aperture value setting operation, moving slidingly over the first and the second conductor patterns. The direction along which the aperture value information varies is detectable by applying the pair of series of pulses thus obtained to the exposure operational circuit through the phase sorting circuit.

    摘要: An exposure control apparatus operating with selection of the diaphragm preselection and shutter preselection automatic exposure control modes is provided with first and second signal shapers arranged to cooperate with a lens aperture mechanism through a common intermediate member. Upon setting of a desired diaphragm value in the lens aperture mechanism, the intermediate member is driven along with the first signal shaper in exactly corresponding relation. In the shutter preselection automatic diaphragm control mode, while the first signal shaper is cut off from connection with an exposure value computer, the second signal shaper is driven for scanning operation to produce ever-varying outputs which are compared with the output of the computer upon coincidence to stop movement of the lens aperture mechanism, thereby the scanning result is translated to the proper diaphragm presetting, as the intermediate member is arranged to delay the start of movement of the lens aperture mechanism from the start of the scanning operation by a time interval determined by taking into account the signal response characteristics of the automatic diaphragm adjusting mechanism.

    摘要: A photographic camera having a manually and automatically adjustable diaphragm is provided with an electromagnetically operated diaphragm scanning mechanism in combination with a manually operable depth of field pre-viewing device to enable a visual determination of the utilizable zone of sharpness in a reflex viewfinder of the camera regardless of the fact that the camera remains in the run down position. For this purpose, the diaphragm scanning mechanism includes a scanning member and a driving member arranged to establish driving connection therebetwen during the automatic adjustment of the diaphragm. Release means is provided and is responsive to the termination of closing operation of the camera shutter for effecting release of the driving connection, whereby the photographer before cocking the camera is enabled to manipulate the diaphragm followed by the pre-viewing device to read off the range of sharpness in dependence on the manual setting of the diaphragm for use in making a subsequent exposure.

    摘要: An image sensing apparatus having a diaphragm of a normally closed type for controlling the entrance of light into an image sensor. The diaphragm is opened from a fully closed state to a predetermined aperture value based on the output of a light measuring element other than the image sensor and is closed again when a first exposure operation is carried out, and then it is opened from the fully closed state to another predetermined aperture value which is based on the signal formed by the image sensor during the first exposure operation and is closed again when a second exposure operation is carried out. An electrical signal formed by the image sensor during the second exposure operation is recorded as a still picture signal, thus giving an advantage that the aging change of the diaphragm and the tolerance of the exposure can be canceled.

    摘要: A camera having an electromagnetic driving source for operating a focal plane shutter in the camera, includes a shutter base plate and a driving arm pivoted on the base plate for swinging movement in a plane parallel to the plate. A group of thin shutter blades are supported on the driving arm parallel to the surface of the base plate. The output shaft of a motor is coupled with the driving arm, and either one of the rotor of the motor, or a permanent magnet forming a part of the stator of the motor, provides magnetic flux parallel to the axis of the output shaft, thereby causing the rotor to rotate the output shaft and drive the focal plane shutter.
