Abstract: An image exposure system for printing an image, comprised of pixels, on photosensitive media based on image data, includes an exposure unit for converting the image data into a light signal for exposure of each of the pixels, a measuring device and a compensator used to correct exposure levels. The exposure unit has light output elements for outputting the light signal for respective ones of the pixels onto the photosensitive media to effect exposure of the image on the photosensitive media. The measuring device is for measuring a density of each of the pixels of the image on the photosensitive media produced by exposing the photosensitive media with reference image data as the image data.

The filtering device has color filters corresponding to respective light spectrums and is operable to interrupt a light beam traveling from the white light source to the photographic paper to separately allow the corresponding light spectrums to pass therethrough. A light amount adjuster is operable to change respective interrupting times of the color filters with respect to a predetermined exposing range.

Abstract: A photographic printing apparatus including a lens controlled to be positioned at a printing position, immediately adjacent a film negative, during photographic printing operation of the apparatus and at a normal position, displaced from the film negative, during other operations of the apparatus.

Abstract: A passing movement analyzer is responsive to a pulse signal from a data reader to calculate the time of passing movement of a negative film. The passing of one frame of the negative film is considered detected when two identification codes of the film are read. When the two identification codes are detected by the passing movement analyzer, a drive signal of a driver contains a number of pulses which differs from that of a standard number, and a correction calculator determines that a transfer error exists and adjusts the pulse setting of the drive.

When the liquid amount is lower than the predetermined level, the float 82 is moved to the second position. Also, the float detecting sensor 64 outputs a float detection signal when the float 82 is located at this second position.

Abstract: A leader section of a film strip having coupler holes in the leading section is inserted into a film guide concavity of a coupling table through a rear slot of a leader sheet placed on the coupling table. The film strip is continuously forced to slide along a curved surface of the film guide concavity until the front end of the leader section of the film strip passes through a front slot of the leader sheet. While the leader section moves through the front slot of the leader sheet, it pushes and bends the coupler tongues upward and lets the coupler tongues snap back and enter the coupler holes of the film strip to bring the coupler tongues into engagement with the coupler holes. Finally, by pulling back and stretching the film strip tight, the film strip is coupled to the leader sheet.

Abstract: A support shaft to efficiently fix a roll of material thereon. The support shaft includes a core support roll having a plurality of axial guide grooves formed in an outer periphery thereof. Each guide groove has a tapered bottom sloping outwardly. In each guide groove is inserted a slider plate having a tapered side and biased inwardly by a ring coil spring provided around the slider plates. A knob is inserted in the core support roll at one end thereof. The knob has a radially outwardly extending guide pin inserted in an inclined guide hole formed in the core support roll. By turning the knob, the guide pin is moved along the guide hole. The knob is thus moved axially, so that the slider plates are pushed axially, thus causing the slider plates to move along the tapered bottoms of the guide grooves and also move radially outwardly to press against the inner surface of the roll.

The image information converted by the image information converter is displayed on a monitor. The exposure condition computing device receives instructions through a control panel to correct the exposure conditions for the image information displayed on the monitor, or instructions not to correct the exposure conditions.

Abstract: A paper magazine made up of a small number of parts and capable of rewinding paper pulled out of the case around the roll of paper in the magazine by turning the paper roll. The paper roll is supported on a roll support shaft provided in the magazine case. The roll support shaft includes a core support rod, a pair of cylindrical end members mounted on both ends of the core support rod, and a core mounted on the core support rod between the end members.
