Abstract: An imaging device includes a mode setting member which allows a shooting mode to be selected from a plurality of shooting modes, a first trigger member for shooting still images, and a second trigger member for shooting motion images. The mode setting member makes at least a first shooting mode and second shooting mode available. In the first shooting mode, a still image is shot by causing a first light emitter to emit light continuously when a first operation signal from the first trigger member is detected and causing the first light emitter to stop emitting light and causing a second light emitter to emit light when a second operation signal from the first trigger member is detected. In the second shooting mode, when an operation signal from the second trigger member is detected, moving images are started to be shot while a first light emitter keeps emitting light continuously.

Abstract: An image blur correction apparatus includes a movable member such as an image blur correction optical system or the like, which moves for image blur correction, an elastic member such as a spring or the like, which movably supports the movable member with respect to a predetermined base member, and has one end connected to the movable member and the other end connected to the base member, and a sliding suppression portion for suppressing sliding of the elastic member relative to the movable member at a contact surface therebetween or sliding of the elastic member relative to the base member at a contact surface therebetween. With this arrangement, the stop position control precision of the movable member, the phase delay characteristics and small vibration response characteristics upon operation of the movable member, and the like are improved.

Abstract: A camera comprises a movable unit, such as a cover and a flash emitting part for flash photography, movable relative to a camera body, for protecting a photographing optical system, an urging member for urging the movable unit, and a resistance member for exerting resistance to a movement of the movable unit caused by an urging force of the urging member, so that the movable unit moves slowly. With its simple construction, the camera gives a good feel to a user during use.

Abstract: An image pickup apparatus in which an image of an object is converted by an image sensor into video signals to be supplied to a monitor is disclosed wherein a control circuit controls the substantial exposure of the image sensor and the monitor is inhibited from displaying the video signals when the exposure is not adequately controlled by the control circuit.

Abstract: An optical system driving device for a camera includes a displacement mechanism for actuating a photo-taking optical system by displacement; a driving mechanism arranged to alternately take first and second states, to shift the displacement mechanism to a first given degree in a given direction when the first state changes to the second state and to shift the displacement mechanism to a second given degree which is less than the first given degree when the second state a changes to the first state; first stopping mechanism for stopping the driving means in the first state; a second stopping mechanism for stopping the driving means in the second state and photographing means for performing photography under a condition that the driving means is stopped by the first and second stopping means.

Abstract: A camera is provided with a focal length variable photo-taking optical system in which a focal length varying cam groove for varying the focal length of the phototaking optical system and a barrel sinking cam groove for stowing the optical system inside a camera body are continuously arranged. In photographing, a focal length varying action can be accomplished continuously from moving the photo-taking optical system out of the camera body. In addition to that, a lens protecting cover is arranged to be automatically openable in association with the action for moving the photo-taking optical system out of the camera body.

Abstract: The disclosed camera has shutter blades which also serve as diaphragm blades and an auxiliary light-metering aperture arranged, upon operation of the shutter blades, to be opened and closed depending upon opening and closing of a main aperture which lies in the path of light from an object to be photographed to a film. A photo-interpreter composed of a light projection element and a photosensitive element optico-electrically detects the size of the opening of the main aperture of the shutter blades. Once the auxiliary aperture has assumed a totally light blocking state from a pre-opened state, the photo-interpreter produces an output signal that initiates counting of light metering data. During flash photography, a flash device is triggered with a timing to make a proper exposure with a signal representing the required aperture value as detected by the photo-interpreter.

Abstract: An electromagnetically driven shutter includes combined diaphragm-shutter blades, the opening and closing of which is controlled by a swingable coil arranged in magnetic fields to travel forwards and backwards. The turns of the coil are made eccentric in relation to the swinging center of the coil, and a drive member for transmitting motion of the coil to the shutter blades is located with its center of inertia at a point almost opposite in position, relative to the swinging center of the coil, from the position of the center of inertia of the coil.

Abstract: In the disclosed camera drive device, a driver electromagnetically driven by coils opens and closes shutter blade members and other exposure members. A holding arrangement holds the blade members closed while the driver controls the other exposure members and a control arrangement actuates the holding arrangement independently of the operating condition of the driver.

Abstract: A camera having a driving member to open and close shutter blades is operated to open a shutter by a force of a spring at a movement speed independently of that of a movable member at a time power is supplied to an electromagnetic driving source, the movable member operating to charge a second spring to return the shutter blade driving member, which second spring charges the first spring, the arrangement being such that the movable member can control the action of an automatic focusing mechanism.

Abstract: A camera having two built-in lenses with selective control of the focal length, wherein a first focal length is obtained by the first lens optical system and, after the first lens optical system has been moved along a lens axis without causing movement of a device for receiving light from an object to be photographed, the second lens optical system is moved to a composite position with the first lens optical system so that a second focal length is obtained by the first and second lens optical systems.

Abstract: A camera having an electromagnetically operated shutter in which a plurality of shutter blades arranged to perform a combined function as a diaphragm are driven to gradually open the shutter from a fully closed state in effecting an exposure. Prior to effecting an exposure, the shutter blades change from a deeply overlapped state to a shallowly overlapped state.

Abstract: A coil-like conductor is provided in combination with a rotor arranged to rotate in different directions depending upon the direction of current flow to this conductor, and the rotor is drivingly connected to open and close blade members. When a first current supply is generated, as the rotor rotates from an initial position in a direction to further close the blade members, a focus adjusting operation is initiated. Upon termination of the focus adjusting operation, the direction of current flow to the conductor is reversed. As the completion of focus adjusting is followed by a subsequent current supply, the rotor is caused to rotate in a direction to open the blade members, thus initiating an exposure operation.

Abstract: An electromagnetic driving device for a camera having a first state for performing a focus adjusting operation of the objective lens by detecting the object distance which is followed after the termination of this focus adjusting operation, by a second state for initiating an exposure operation. A driven member is movable from an initial position in either 1st or 2nd direction by controlling the direction of current flow to a coil positioned in a magnetic field of permanent magnets. Movement of this driven member in the 1st direction controls the focus adjusting operation, and movement in the 2nd direction controls the exposure operation.
