Abstract: A compact and inexpensive illuminating light source apparatus for a photographic printer, which is designed so that infrared rays emitted from a lamp are reused without dissipating as heat, thereby considerably improving the light source efficiency, and that color and other characteristics are not affected by replacement of the lamp, and further that the apparatus is easy to produce and simple in arrangement. All the components of light that is emitted from a filament (FM) of a lamp (S) are reflected by a total internal reflection reflector (R1) having a paraboloid of revolution, and the resulting parallel beam of light is perpendicularly incident on an infrared reflecting plate (RP). The visible light component in the incident light passes through the infrared reflecting plate (RP) and is used to print a film. The infrared component is reflected by the infrared reflecting plate (RP) so as to return to the filament (FM) of the lamp (S), traveling backwards along the optical path.

Abstract: An information recording apparatus has an LUT storing a table, which represents a relationship between a key code and 2401 combinations of density correcting data and color correcting data. The combinations are arranged in the table in an order of frequency of occurrences thereof. Each combination constitutes exposure correcting information in combination. With a photo film exposed, a photoprint is produced in initial photographic printing from an imaging frame on the photo film. A key code is read from LUT, with an address of the exposure correcting information used in the printing. An imprinting head imprints the key code to the photoprint or containing sheath. With the key code imprinted, the exposure correcting information is usable in further photographic printing.

Abstract: When images are photographed by using a photographic film at which a magnetic recording layer is provided, photographic information regarding the entire film and photographic information regarding respective image frames can be magnetically recorded. A method and an apparatus are provided for the recording or for printing the photographic information which is magnetically recorded. In a case in which a printing area is limited, magnetically-recording of or printing of non-prior information is limited so that prior information is printed on the printing area prior to the non-prior information. For example, the information regarding an image frame is printed on the printing area of the back surface of the photographic printing paper prior to the information regarding the entire film.

Abstract: A light source for a photographic printer which is designed so that almost all light energy emitted from a diffusing device can be utilized for printing, thereby markedly improving the light source efficiency. The light source is used in a photographic printer which illuminates a film (F) and projects an image of the film (F) onto photographic paper (P) to print the projected image on the paper (P). A diffuser (BD), which is disposed in an illuminating optical path in the vicinity of the film (F), is caused to perform reciprocative vibration in parallel to its own plane by a vibrating device (B), e.g., a voice coil, during the exposure time, so that, even if an image of dust or a blemish on the diffuser (BD) is formed on the print, the image becomes blurred on the photographic paper (P) because it moves during the exposure process, thereby preventing the print from being affected by the image of such an undesired object.

Abstract: A printer/processor has at least two rinsing or washing vessels interconnected by a rectangular tube passage through which a negative film passes. Two transparent plates form the upper and lower walls of the passage, a light source unit being mounted above the passage and an image pickup unit being mounted under the passage. The image pickup unit scan an image on a negative film immersed in the rinsing solution while it passes through the passage. Image data outputted from the image pickup unit is immediately sent to an image processing unit of a printer/processor. The image processing unit processes the image data so that an original frame of the negative film can be properly printed on a color paper. A printer unit of the printer/processor prints a color image reproduced from the image data onto the color paper. The printer/processor develops the printed color paper to make photoprints.

Abstract: A photographic printing apparatus in which images recorded on a photographic film are printed onto a photographic paper as printed images of print sizes of different aspect ratios and in which a printed photographic paper is conveyed distances corresponding to the print sizes and is cut. Indications symbolizing the print sizes are recorded at the photographic paper. The print sizes are identified by detection of the indications. Areas of the photographic paper in which the indications are detected based on identified print sizes are controlled. Mistakes in cutting can thereby be prevented.

Abstract: A film developing process and a printing process are simultaneously executed to reduce the photo finishing time. A film processor has a developing unit, a drying unit, and an image pickup unit. A color negative film, sequentially subjected to the developing process and drying process, passes through the image pickup unit, at which an image of each original frame of the color negative film is picked up. The obtained video image data is sent to a printer-processor. The printer-processor has an image processing unit, a video printer unit, and a paper processor unit. The image processing unit corrects density and color of a video image. The video printer unit prints the video image on a color photographic paper in accordance with the processed image data. The paper processor unit develops and dries the printed color photographic paper, and cut it into photoprints by a cutter.

Abstract: A photographic film is provided with decimal numbers and bar codes both representative of serial frame numbers. When a sensor reads a bar code, measurement of the advanced length of the photographic film is started to obtain a distance of either the bar code or the decimal number relative to the sensor. After the positioning of a frame to be printed in a film framing mask at the printing station, a fram e number represented by a decimal number or bar code whose moved distance is within a predetermined range of distances is selected, thereby identifying the picture frame in the film framing mask to have the drawn frame number.

Abstract: Two bar code sensors are disposed at opposite sides of a passage of a photographic film, each bar code sensor having two photosensors disposed along a line perpendicular to the transportation direction of the photographic film. Each time a photographic film is fed by a predetermined distance, signals outputted from the two bar code sensor units are sampled and are compared with the signals obtained at the second preceding sampling timing to convert them into binary signals. Based on the data configuration of binary signals, i.e., based on the discrimination between the start code and end code, or the presence or absence of a clock track, automatic discrimination is performed between DX bar code data and frame number bar code data which then are decoded into a film type and frame number, respectively. The setting conditions of a photographic film also can be determined based on the bar code data configuration. An alarm is output if the setting conditions are not normal.

Abstract: When printing a frame of a film immediately after developing the film, a mini-lab photofinisher observes the frame that is positioned in a printing station of a mini-lab type printer-processor, so as to input exposure correction data as needed. While positioning the frame in the printing station, frame number bar codes recorded on the film are read to determine the number of the frame. The determined frame number is printed on the reverse of the print image made from that frame. After printing all the frames, a bill printer prints the frame numbers of the printed frames and the corresponding exposure correction data, along with the photofinishing price. When making extra prints, the necessary number of extra prints is written in the bill slip, so that the photofinisher may finish the extra prints with substantially the same quality as the original print by referring to the exposure correction data printed in the bill slip.

Exposure correction data of a film frame is provided based on inspection data and scanning data of frame.

Abstract: A photographic printer having a roof type mirror with a reflection surface of a roof type. The roof mirror is disposed at a 45 degree angle relative to the optical axis of the printing lens. Incident light is reflected twice by the roof mirror, and thereafter it reaches either a photosensitive material disposed at the focal plane of the printing lens, or a monitor screen. The roof mirror reverses the right and left sides of an image so that the right and left sides of an image projected upon the monitor screen or photosensitive material are the same as those of an original image of the photographic film. In a preferred embodiment, when the roof type mirror is inserted within the printing optical path, the light reflected by the roof type mirror reaches a first exposure station, and when the roof type mirror is retracted from the printing optical path, the light passed through the printing lens reaches a second exposure station.

Abstract: A photographic printer has a film carrier which shifts by 90 degrees in accordance with a frame size of a photographic film. An anisotropic diffusion plate having a light diffusion property only in one direction is attached to the bottom of the film carrier. The anisotropic diffusion plate prevents the quality of photoprints from being degraded by comspicuous scratches on a photographic film which might otherwise be printed on a photographic paper. As the direction of the film carrier is changed in accordance with the frame size, the direction of the anisotropic diffusion plate is changed together with the film carrier.

Abstract: A reflect type photographic printer having a flat plate mirror and a roof type mirror which are set selectively in an L-shaped printing optical path. If photographic film is loaded in the film carrier with its photosensitive emulsion layer directed upwardly, the roof type mirror is set within the printing optical path; if the film is loaded with the emulsion layer directed downwardly, the flat plate mirror is set within the printing optical path.

Abstract: Disclosed is a collating device for collating the images on a photographic film with those printed on a printing paper from the photographic film while conveying the film and the printing paper. The collating device includes a reading device for reading a frame number for identifying the frame image on the film, and a printing device for printing the frame number which has been read by the reading device on the printing paper on which has been printed the image on the film which corresponds to that frame member. The frame numbers of the film are printed on the printing paper on which have been printed the images on the film. In consequence, the print images on the printing paper are easily made to correspond to the corresponding frame images on the film, and designation of the frames is facilitated.
