A photographic lens and test chart provide for a method of inspecting and adjusting the focus of the lens. The test chart is obliquely inclined relative to a plane perpendicular to the viewing axis of the photographic lens. Test photographs are taken of the test chart under low magnification and high magnifications the test photographs enabling the photographic lens to be adjusted for proper focus.

Focus inspection device and focusing method

A method and apparatus for producing index prints makes the trend of compensation for main prints coincide with the trend of compensation for the index prints. When a scanner determines an exposure compensation amount for each frame based on image data of each frame of a negative film, the information representing the exposure compensation amount for each frame is transmitted to the drive controllers via a controller. In a main print section, an exposure process is performed by the drive controller based on the information regrading the exposure compensation amount for each frame, thereby obtaining a main print. In an index print section, an exposure process is performed by the drive controller based on the same information regrading the exposure compensation amount for each frame, thereby obtaining an index print. Also, a density adjusting method easily and automatically adjust unevenness in density produced in an image printing stage. In a test mode, an image (gray image) with a uniform intermediate gradation is printed on a printing paper. A pixel having the maximum density is selected. Differences in density between the pixel having the maximum density and other pixels are calculated, and the gradations of the respective pixels are shifted based on the differences. Thus shifted gradations are registered as standards for the respective pixels.

Method and apparatus for producing index prints and density adjusting

A method and an apparatus for printing images on different mediums, such as images recorded on a photographic film and index print images onto photographic paper while an image printing device is reduced in size. A film carrier is positioned to a first position so that images recorded on a negative film set on the film carrier are exposed by a light source. Further, the film carrier is moved to a second position so that images formed on a liquid crystal panel are exposed by the same light source as that used for the exposure of the images on the negative film.

A photosensitive material processing apparatus adaptable for occasional operation is provided, comprising a processing tank filled with processing solution and an adjustable closure for controlling access to the tank through its top opening. The adjustable closure includes a fixed lid, a movable lid, and a drive for the movable lid. The operating openness, which is the surface area of the solution open to the ambient atmosphere divided by the volume of the solution, is set in a specific range and the quiescent openness is up to 70% of the operating openness.

Photosensitive material processing apparatus

A photosensitive material to which an image has been exposed is successively dipped into treatment liquid such as developer wherein development or other treatment is conducted. The photosensitive material drawn out from each treatment liquid is held by holding rollers and the treatment liquid is wiped off. Since washing water is supplied to these holding rollers to wash and wipe off the treatment liquid from the photosensitive material and the water is supplied to the treatment chambers, the holding rollers can be kept clean.

Structure of washing conveyance roller for photosensitive material

A light-sensitive material feeding rack for feeding a light-sensitive material along a feeding path within a processing tank by holding the material between paired feed rollers. The rack has guide plates extending along the feeding path for guiding the material to the light-sensitive material entrance side of the paired feed rollers. These guide plates are each rotatable about the ends thereof that are closer to the light-sensitive material entrance side. When the rack is to be cleaned, the guide plates are rotated so as to open the interior of the rack, thereby facilitating the cleaning of the rack. After the completion of cleaning, the guide plates are rotated in the opposite direction to be returned to their original condition. Even after the returning of the guide plates, the positional relationship between the feed rollers and the end portions of the guide plates that are closer to the entrance side can be very precisely maintained.

Light-sensitive material feeding rack

A plurality of patrones accommodating films to be developed are housed in a magazine, and this magazine is connected to a developing system. A conveyor for consecutively feeding leaders connected to the tips of the films is provided in the magazine, and these leaders are fed one by one into the developing system, whereby all the films are automatically developed.

Film supplying apparatus

A photosensitive material guide structure for use in a developing apparatus adapted to develop a photosensitive material having been subjected to light exposure has at least one pair of feed rollers which feed forward the photosensitive material while clamping it therebetween within the developing apparatus. Both axial end portions of at least one of the pair of feed rollers are reduced in diameter. Accordingly, when the rollers clamp the photosensitive material to feed it, both the lateral edge portions of the photosensitive material are subjected to a clamping force which is weaker than that applied to the other portion of the material.

Photosensitive material guide structure for developing apparatus

A drying apparatus for drying photographic paper includes a rotary drum and a duct having a recess which is provided with air outlet bores. A photographic paper passing area is defined between the outer periphery of the drum and the recess of the duct. The warm air blown out of the air outlet bores presses the side (the reverse side) of the photographic paper which is opposite to the emulsion layer side thereof against the outer periphery of the rotary drum, thereby maintaining the emulsion layer side of the paper in a non-contact state while the paper is being transported. The rotary drum is provided with bores through which the warm air is sucked in so as to suction-hold the photographic paper on the outer periphery of the rotary drum, whereby the photographic paper is also heated from the reverse side thereof. If the rotary drum is rotated at a higher peripheral speed than the speed of travel of the photographic paper, if it possible to prevent the formation of any dent in the reverse side of the photographic paper by the action of the suction bores.
