    摘要: An electromagnetic shutter release device is provided with an electromagnet including an armature. A control circuit including two delay circuits are connected to the electromagnet for energizing same for a first period upon the initiation of the shutter release operation and thereafter energizing same for a second period upon the initiation of the exposure operation. The armature is mounted for movement to a first position during the first period, movement into a second position between the first and second periods and maintaining of same in the second position in the second period and into a third position after the second period. The movement of the armature from the first to the second position initiates the exposure operation and the movement of the armature from the second to the third position initiates the aperture closing operation which in turn begins the energization of the electromagnet during the second period whereupon the armature is maintained in position. As a result, a device is obtained which is technically and economically advantageous since it uses a single electromagnetic assembly for two purposes.

    摘要: A focal point adjusting and change-over mechanism for an automatic focusing camera, including a mechanism for restricting a position of the camera photographic lens in response to a distance sensing signal, and a change-over mechanism manually operable to at least two positions including an automatic position and a manual position. The restricting mechanism is operative to provide automatic focusing of the lens when the change-over mechanism is set at a position for automatic operation, and the change-over mechanism renders the distance sensing signal or the restricting mechanism inoperative when set at the position for manual operation, and thereby manual focusing is carried out in accordance with the manually set position of the change-over mechanism in the manual position.

    摘要: The system is provided with an optical means capable of forming images obtained through a first light passage and a second light passage. A light detecting system is formed of a plurality of light responsive elements which receive the image. A focus detection signal is obtained by detecting the differential between the maximum and the minimum intensity of the light pattern or the maximum ratio of the maximum intensity to the minimum intensity using the electric output of the light responsive elements corresponding the light pattern of a composite image.

    摘要: An automatic focusing apparatus for use in a camera has an operating member which moves from a rest position to a depressed position. An actuating member is rotatably mounted on the operating member and a detecting member is mounted for movement from a first position to a second position and is biased normally into the first position. The actuating member enables the detecting member to move from the first to the second position in response to the movement of the operating member from the rest position to the depressed position and disengages from the detecting member when the operating member is in the depressed position to enable the detecting member to move from the second position to the first position under the action of its bias. A device produces an electric signal corresponding to the position of the detecting member and a focus scanning member is movable over its entire focus scanning range in response to the movement of the detecting member between its first and second positions. An electro-magnet is provided for stopping the movement of the detecting member during its movement from the second to the first position when the electro-magnet is actuated. A focus detecting module receives a signal from the device synchronously with the movement of the focus scanning member during the movement of the detecting member to the second position to determine the signal from the device corresponding to the in-focus position and for actuating the electro-magnet to stop the return movement of the detecting member to its first position when the signal from the device is equal to that determined for the in-focus position. In this way, the camera lens can be focused with reduced error.

    摘要: In a timepiece having a case and having a minute hand and an hour hand for indicating time, an alarm signaling device generates an alarm by detecting the phase of two sets of gears. One set of gears comprises an hour hand gear and an hour detecting gear and the other set comprises a minute hand gear and a minute detecting gear. The two sets of gears are concentrically mounted for rotation and the minute detecting gear is positioned between the minute gear and the one set of gears. The minute detecting gear has a contacting sliding contact with the minute gear. The alarm signaling device further includes an alarm signaling time setting wheel having an axis of rotation parallel to that of the two sets of gears and a first gear and a second gear engaging the minute detecting gear and the hour detecting gear respectively.

    摘要: A camera shutter has a set of opening blades and a set of closing blades sequentially driven from cocked positions to released positions to effect an exposure. During cocking of the shutter, the opening and closing blades are driven to their cocked positions by opening and closing mechanisms which include springs for permitting continued movement of the opening and closing mechanisms in the cocking direction after the opening and closing blades are driven to their cocked positions. Upon completion of the movement of the opening and closing blades to their cocked positions, the springs undergo further compression thereby permitting continued cocking movement of the opening and closing mechanisms independent of the opening and closing blades.

    摘要: A single-lens reflex camera shutter having an operating ring driven in one direction by a gear-rack and pinion combination. The operating ring actuates the diaphragm and shutter blades and is stopped by a stop lever during the taking of an exposure. The stop lever is locked during the taking of an exposure by a signal lever that signals the taking of an exposure and is released upon completion of an exposure to allow the operating ring to continue in its travel and carry out opening of the shutter and opening of the diaphragm blades.
