摘要： An exposure time control circuit for a camera shutter having a light-responsive element that controls charging of a capacitor as a function of the intensity of the light from a scene to be photographed. The charge of the capacitor at a certain level activates a switching circuit that initiates closing of the camera shutter. A light-intensity indicating circuit is directly connected to the light-responsive element for indicating the intensity of the light received from a scene to be photographed so that the camera shutter speed may be set accordingly. Photographic exposure and light readings are taken independently with control switches that need not make use of a change-over switch for connecting and disconnecting the light-intensity indicating circuit to the light-responsive element.

摘要： An automatic lens focusing mechanism including a displaceable operating member, a focusing mechanism cooperative with the operating member for changing the focus of a lens as the operating member is displaced, and a mechanism comprising a control member displaced by the operating member as the operating member is displaced. An electromagnet is effective to hold an armature when it is energized. When the electromagnet is not energized the armature is mounted for sliding across a face of the electromagnet adjacent and parallel to the electromagnet face. A focus detecting mechanism energizes the electromagnet when the control member is at a position corresponding to a focused condition of the lens for holding the armature and the control member at a position corresponding to the focused condition to thereby hold the lens at the focused condition.

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.
