Abstract: The present invention relates to an optical system position controlling device applicable to camera or other optical instruments which require focusing. The subject device includes a position detecting means having a light receiving portion or surface provided with a photosensitive element which generates an electrical signal in correspondence with the brightness of an object to be photographed. The light receiving surface is moved along the optical axis of an image forming optical system to detect the position of an image formed by the image forming optical system, and when the image is not formed at a predetermined position, a portion or all of the image forming optical system is so controlled to form the image at the predetermined position.

Abstract: The disclosed camera ordinarily uses an electromagnetic release device. A supplemental mechanical release device is enabled only when the electromagnetic release device's battery is absent from the battery case. The release operation is then carried out by the mechanical release device.

Abstract: In the combination of a camera and a motor drive unit, an exposure adjusting device is provided. This exposure adjusting device is manually controllable either by rotating a diaphragm adjusting ring that is in engagement with a presetting ring. This rotation is followed up by a scanning member which is coupled to a variable resistor that is connected in a control circuit for an exposure meter to attain correct adjustment of the diaphragm value and shutter time in conformity with the available light conditions. This exposure adjusting device also is automatically controllable through operative connection of the diaphragm scanning member with a control member which is provided in the unit. The control member movement is initiated and terminated by means of an electromagnetic actuator and arrest respectively with electrical power supply from a unit battery. With the camera detached from the unit, manually presetting the diaphragm is only selective, but the consumption of electrical energy from the camera battery is minimized. The driving torque of the film winding lever, moreover, is reduced by an amount necessary to overcome a strong drive spring for the diaphragm scanning control member.

Abstract: An electric motor drive device for a camera is arranged such that, in cases where power supply to a film winding motor is stopped with the camera still in an incomplete winding state and when the film comes to the end thereof after completion of a photographic operation on every frame, the power supply to the motor is resumed in response to a film rewinding completion signal produced from a film detection switch upon completion of film rewinding so that the camera can be brought into a winding completion state. This arrangement solves the problem of phase discrepancy arising between the camera body and the electric motor drive device when they are separated from each other.
