A lens-fitted film unit includes: a main body; a photographic lens provided in the main body, having an aperture value; an aperture provided in the main body; a shutter provided in the main body, having a shutter speed; a photographic film loaded in the main body, having image frames each including an unexposed portion and a pre-exposed portion on which a latent image has been formed; and a masking member for masking the pre-exposed portion of the photographic film when a photographing operation is conducted. The latent image has been formed on the photographic film with a same exposure amount as that obtained when an object to be photographed having a brightness of not less than 10 and not more than 12.5 in terms of light values in which a photographic film whose ISO sensitivity is 100, is exposed to light with an aperture value of the photographic lens set by the aperture and with the shutter speed of the shutter.

Lens-fitted film unit

A photographic device set including: a photographic device having a shutter device, a camera lens, a diaphragm and a photographing operation section; a photographic film built in the photographic device in advance; and a packing material with which the photographic device is packed. In the photographic device set, the packing material has a transparent film and is provided with opaque portions at an area corresponding to the photographing operation section or to the camera lens of the photographic device.

Photographic device set

A camera in use with a photographic film in a cartridge. The camera includes: a cartridge chamber for accommodating the cartridge, in which the cartridge includes a spool and a bar code disk; a regulation member for regulating a location of the spool in the cartridge chamber; a regulation member release for releasing a regulation of the location of the spool by the regulation member; a driving shaft for being coupled with the spool to rotate it; a generator circuit for generating reference pulse signals which correspond to a rotation cycle of the spool; a bar code reader for reading a bar code on the bar code disk in rotation so as to obtain film information respectively from each unit block of the bar code; and a controller for controlling the bar code reader in synchronism with the reference pulse signals so as to obtain the film information when the driving shaft is coupled with the spool and the photographic film is being loaded to a photographic position where a first frame of the photographic film is subjected for picture taking with the camera.

Camera for use with photographic film in a cartridge

A magnetic head supporting mechanism for supporting a magnetic head for writing and reading information on a magnetic layer of a photographic film by tracing the information with the magnetic head in a predetermined conveyance direction of the photographic film. The mechanism includes: a fixing frame, which is fixed to the body of the magnetic head supporting mechanism, for pivotally supporting a head supporting frame and the magnetic head; and the head supporting frame for supporting the magnetic head. The fixing frame includes recess portions, each positioned at each of both sides of the fixing frame in relation to the predetermined conveyance direction, for movably supporting semi-circular protrusions of the head supporting frame; and the head supporting frame includes the semi-circular protrusions, each positioned at a front side and a back side of the head supporting frame in relation to the predetermined conveyance direction, for movably coupled with the recess portions of the fixing frame.

Supporting apparatus for a magnetic head

A camera having a trimming function capable of recording trimming information includes a lens barrel having a picture-taking lens capable of moving between protruding and retracting positions, a lens barrel driver to drive the lens barrel, a zoom viewfinder driver to change a magnification of the viewfinder, a film winder to winding a photographic film, a film rewinder to rewind the film, a motor to feed the film. The camera further includes a driver to drive the film winder when the motor is forwardly rotated, and also to drive the film rewinder or the zoom viewfinder driver when the motor is reversely rotated, and a switch to switch over between the zoom viewfinder driver and the film rewinder in accordance with a position of the lens barrel. The camera yet further includes a controller to activate the film rewinder by the reverse rotation of the motor when the lens barrel is located in a retracting position, and also to activating the zoom viewfinder driver by the reverse rotation of the motor when the lens barrel is located in a protruding position.

Camera having trimming function

A photographic roll film cartridge in which a roll film is stored in an initial packaged condition before being used for photographing. In the initial packaged condition, the leading edge portion of the roll film protrudes out of the cartridge by a length of 10 mm to 25 mm.

A display device in a real image type viewfinder includes an optical member having an image formation surface thereon, which is provided between an objective lens and an eyepiece. An object image is formed by the objective lens on the image formation surface. A display section in a view field frame to display the view field frame is provided when an inclined surface portion is formed in a direction in which a peripheral portion of the image formation surface of the optical member is protruded with respect to the image formation surface.

Display device in view-finder

A zoom camera being capable of changing a distance measuring direction to measure an object distance, and more particularly a camera which indicates the distance measuring direction overlapped on an object image in a view finder display. An object image is displayed in a finder display through an optical system, thereby the magnification of the object image in the view finder changes in accordance with a zooming of the camera. An indicator array is arranged on the view finder display, and the distance measuring direction is indicated by an activation of an indicator element of the indicator array located at a corresponding position to an object position in the distance measuring direction. For the purpose of coordinating with the change of magnification of the view image, the corresponding position is determined based on the focal length information obtained by a focal length detector in addition to distance measuring direction information and distance information, each obtained by each of a direction detector and a distance detector.

A variable focus camera includes a photographing lens constituted by at least two components, and changes the position of a magnification adjusting lens of a finder by a cam barrel of the photographing lens. In this camera, at least two magnification correction cams for extending the components of the photographing lens and having a focal-point correction function are formed on the cam barrel, and a magnification of the photographing lens is caused to coincide with a magnification of the finder by the magnification correction cams.

Variable focus camera

A motor driven camera in which a reversible motor is used to wind and rewind the film, and to perform some reciprocative camera function. The camera is constructed so that film will be wound in the forward direction of the motor. The reciprocative camera function is performed by reversing the direction of the motor. An additional shifting step is necessary to rewind the film, the film being rewound when the motor is in the reverse mode and the shifting step is completed. Examples of reciprocative camera functions include lens focus, and retracting a flash or lens cover.

Electric camera

The present invention relates to a camera that is capable of automatically operating the wind/rewind of film and the lens movement required for the focal length change or collapse of the taking lens thereof.
