In a film scanner, for reading an original image on a photographic film, provided with an optical system for irradiating light to the original image on the photographic film and for focusing light from the photographic film so as to form an image and photoelectically converting elements for photoelectically reading the formed image by the optical system, there is further provided an image resolution regulator to regulate image resolution of the read image in accordance with the size of the original image to be read.

Image reading apparatus

A camera for reading film information expressed with a bar code, which is provided on a bar code plate being rotatable with a spool of a film cartridge, through a window of the film cartridge. The camera includes: a driver for rotating the spool; an optical reading device for reading the bar code, and for generating a bar code information including the film information; a detecting circuit for detecting a reference position of the bar code according to the bar code information, and a memory device for storing the bar code information being read by the optical reading device. In the camera, the driver rotates the spool in a film rewinding direction after a film in the film cartridge is rewound so that the detector circuit detects the reference position of the bar code according to the bar code information stored in the memory device, and the driver rotates the spool according to the reference position so as to locate a bar code portion corresponding to exposed state of the film. The camera further includes a release pin for releasing a spool locking mechanism which cannot be inadvertently released during the cartridge loading or cartridge removal.

Camera with bar code reading apparatus and spool locking mechanism

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 camera for reading film information expressed with a bar code, which is provided on a bar code plate being rotatable with a spool of a film cartridge, through a window of the film cartridge. The camera includes: a driver for rotating the spool; an optical reading device for reading the bar code, and for generating a bar code information including the film information; a detecting circuit for detecting a reference position of the bar code according to the bar code information; and a memory device for storing the bar code information being read by the optical reading device. In the camera, the driver starts rotating the spool in a film rewinding direction when the film cartridge is set in the camera and before a film in the film cartridge is loaded to a photographing position so that the optical reading device reads the bar code information, the detecting circuit detects the reference position, and the memory device stores the bar code information.

Camera with a bar code reading apparatus

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.
