Abstract: An automatic patrone loading camera includes a patrone chamber, a rotating shaft, a detector, and a control section. The patrone chamber houses a patrone. A film is inserted in the patrone in the winding shaft direction while the film is wound around the outer surface of the patrone. When the patrone is housed in the patrone chamber, the rotating shaft is engaged with a winding shaft of the patrone so as to rotate the winding shaft. The detector detects an extracted state of a leader portion of the film. The control section controls a rotating direction of the rotating shaft on the basis of a detection value from the detector.

Abstract: A camera provided with an automatic focusing apparatus having a lens-driving device (40) to move a photographing lens (50) in the direction of an optical axis to a focal position on the basis of a distance information from a distance-measuring device, a lens-positioning device (30) to determine a position of stoppage of the photographing lens (50) moved in the direction of the optical axis, and one motor (60) driving the two devices (40) and (30).An automatic focusing method of detecting a distance to an object by a distance-measuring device, moving the photographing lens (50) in the direction of an optical axis on the basis of the information on the distance, determining a position of stoppage of the photographing lens (50) at the same time substantially, and stopping the photographing lens (50) at this position.

Abstract: In a camera including a driven member which is moved by a motor powered by a battery from a photographing position to an initial position through a gear train, and is stopped by mechanical damping, energization of the motor after a photographing operation is completed is controlled by pulse energization after the motor is started.

Abstract: An automatic focusing apparatus for a camera wherein a distance measurement signal is stored as a digital value, pulses corresponding to a distance, which are generated upon rotational movement of a lens along an optical axis through a motor, are counted, and a stop pawl for stopping the lens is driven in accordance with the count value. A pulse width of the pulses of the pulse signal is detected, the pulses of the pulse signal are counted, and when the number of the counted pulses corresponds to the stored digital value, the stop pawl is driven after a delay time which is determined based on the detected pulse width of a pulse of the pulse signal.

Abstract: A light-shielding apparatus of a camera having a collapsible barrel provides a fixed cylindrical light-shielding member between a movable portion of the collapsible barrel and a frame of a camera body. The outer surface of the light-shielding fixed member can be overlapped with the movable portion.

Abstract: A camera comprising a lens unit which is slidable between two stoppers along an optical axis for varying a focal length thereof, a lens unit driving member having at least two sections which are connected to circumferential parts of the lens unit, means for providing the lens unit driving member with driving force, and a stroke absorbing member through which the driving force is transferred to the lens units, whereby the lens unit is capable of being resiliently pressed toward the stoppers when the means for providing driving force is overrunning.

Abstract: An automatic focusing camera having a driving mechanism for moving a taking lens on the basis of a signal provided by a distance measuring device. The lens position is controlling by a cam member capable of being turned stepwise in one direction about the optical axis of a taking lens by a pulse signal given by the distance measuring device. The driving mechanism has a light quantity controlling movable coil member and a taking lens driving and controlling movable coil member. Both the light quantity controlling movable coil member and the taking lens driving and controlling movable coil member are disposed within a gap and exposed to a common magnetic field.
