摘要： In an electromagnetic release for a camera a normally de-energized electromagnet is coupled with unitarally joined elongated pole pieces, and when energized, generates a magnetic flux opposing the magnetic flux of a permanent magnet. A moveable, magnetizable armature adjacent corresponding ends of the pole pieces is normally attracted by the pole pieces as a result of the flux of the permanent magnet when the electromagnet is deenergized. The permanent magnet is positioned between the pole pieces. A spring biases the armature to disengage it from the faces of the pole pieces.

摘要： A shutter control circuit which normally responds to ambient light switches automatically to a flash mode in response to a charge signal from a flash unit. The light flash eliminates the charge signal. To prevent the absence of a charge signal from returning the shutter to daylight control, a shutter closing signal is generated before a flash synchronizing contact is closed and hence before the charge signal ends. However shutter closing action is then started only after a delay that provides time for the flash to occur when the shutter is fully open.

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： A camera of the type in which the shutter actuator is operated by means of an electromagnet or a permanent magnet associated with a solenoid has a film winding mechanism and a shutter tensioning mechanism operatively connected with each other through an improved interconnecting mechanism which includes a cam arrangement and a switching arrangement for the electromagnet or the solenoid. The cam arrangement is constructed as having complementary camming surfaces to facilitate the minimization of dimensions of the interconnecting mechanism. During the film winding or shutter tensioning operation, the electromagnet or the solenoid is rendered inoperative or operative respectively by the switching arrangement to thereby reduce the torque of a single operating member for the film winding and shutter tensioning mechanisms.
