摘要:
A system and method for reading machine-readable information from a carrier and printing information onto said carrier or other means is presented. The system comprises a reader means, storage means, printer means, enable means, read repeat means and annunciator means. Circuitry is provided fordetermining when an unsuccessful scan has resulted and thereafter commanding a rescan of the code until a successful scan is obtained or a predetermined limited number of unsuccessful rescans have been completed. The system may include means for modifying the relative position of the scanning means with respect to the carrier during successive rescans. When successful read and print cycles are completed, the carrier means is positioned appropriately for human retrieval. An annuciator means is employed to signal the human controller when the allowable number of rescans has been exhausted without successfully reading the coded information. The system further provides apparatus for adjusting the alignment of the printer means.

A specific ion sensor comprising a solid state membrane connected by a solid junction to an output terminal. The membrane has a conductive backing which is die pressed in place along with the membrane itself. An electrical lead is bonded to the conductive backing as with a conductive epoxy, and the assembly is then coated on the sides and back with an insulative coating. Thereafter the coated assembly is sealed in place within a sensor housing, and the electrical lead is connected to an appropriate output terminal mounted on the housing.

In a high speed package printer that produces photographs of varying size from film negatives, different cropping apertures are used with different lenses for different prints. In order to provide a large combination of different cropping apertures with different lenses the lenses and cropping apertures are separately selected for each print. The high speed package printer includes a light source, a diffusion plate, a plurality of cropping apertures on an aperture member which can be moved to select which aperture will block light from the diffusion plate. The light from the cropping aperture then passes through a negative for projection by a lens onto photographic paper for printing pictures. Separate means for moving the aperture member and for selecting which lens will receive light from a negative after it is provide a selection of all combinations of lenses and cropping apertures such that the photographs produced can have different sizes and shapes.
摘要:
An apparatus and method relating to the print quality of a high speed package printer that produces photographs of varying size from film negatives. The high speed package printer includes a diffusion plate and a diffusion plate cleaner, and a film cleaner to remove dust and unwanted particles from the diffusion plate and film, thereby increasing the quality of prints from the printer. The apparatus increases print quality by having a plate that diffuses light from a light source shining on the photographic paper, and by automatically cleaning the diffusion plate with a brush during the time between exposures and while the photographic paper and photographic film are advancing. The apparatus also increases print quality with a film cleaning arrangement that includes applying an electrostatic charge to the film, brushing the surface of the film, vacuuming the surface of the film and using sticky rollers to remove any dust or other particles during the advancement of the film to the light source and during the time between exposures.
摘要:
An improved high speed package printer for producing a plurality of high quality photographs of varying size, shape, and style based on one or a plurality of different film negatives. The improved package printer of the present invention accomplishes the goal of increased throughput and speed through the use of an automatic paper-loading feature, ultrasonic proximity sensors for dynamically measuring paper-slack loops, off-center printing for eliminating the need to advance the paper for punching after each exposure, a rotational prism for creating 10".times.13" photographs without physically rotating the film, a 13-UP lens deck including 12 wallet lenses and a single 5".times.7" retro-focus lens for creating 12 wallet-sized photographs and one 5".times.7" photograph from a single exposure, an automatic diffusion plate cleaner for eliminating the system down time associated with manual diffusion plate cleaning, an improved filtering arrangement for equalizing the amount of energy emitted from each lamp within a photographic lamphouse, and bi-directional film movement for producing a single composite containing a plurality of different images or poses. The high speed package printer of the present invention also boasts an improved film cleaning arrangement for increasing the quality of the prints, as well as penumbra masking for producing photographs having sharply delineated borders.

A photographic slide mounter cuts photographic film transparencies from a photographic film web and inserts the transparencies into slide mounts. A slide mount is advanced along a slide track to a position adjacent a knife where the slide mount is flexed to provide an insertion opening. The film web is advanced along a film track until a leading end of the web is partially inserted into the insertion opening. A first plurality of rollers are positioned over the film track and a second plurality of rollers are positioned under the film track to prevent transverse curl of the film web as it is advanced toward the insertion opening. A pair of curved shoes is mounted over the film track proximate the knife to prevent longitudinal curl of the film web as it is advanced through the knife and into the insertion opening. The knife is provided with tapered portions to align the web as it passes the knife. After the transparency has been severed from the film web by the knife, the partially inserted transparency is engaged and inserted fully into the slide mount as the slide mount and transparency are advanced away from the film track. The slide mount insertion opening is maintained in a flexed open position as the transparency is engaged and fully inserted by a slide mount spreading means having a flared portion. Once the film transparency has been fully inserted into the slide mount, the slide mount insertion opening is allowed to close.

A photographic film splicer includes a supporting pad or platform on which ends of photographic film strips are supported, and a movable heat block which applies heat and pressure to a heat activated splice tape and the film ends. A heated die attached to the heat block and a plurality of spring-loaded pins supported by the platform apply heat and pressure to a portion of one of the film ends proximate the splice tape to deform a portion of the film strip. The deformed area of the film strip acts as a ramp proximate the splice tape which guides film strips over the interface of the splice tape and the film strip during operations in which the web of photographic film is cut into individual lengths and in which the individual lengths of film are stacked.
