Abstract: Provided is a pipette device that achieves both suction and discharge of a large amount of fluid and high-precision discharge of a minute amount of fluid. The pipette device includes: a first syringe 30 that is capable of suctioning fluid and is capable of discharging fluid with a predetermined discharge precision; a second syringe 40 that is capable of suctioning fluid and is capable of discharging fluid with a higher precision than the first syringe; a nozzle 70 provided in common to the first syringe 30 and the second syringe 40; a flow path 60 that causes the first syringe 30 and the second syringe 40 to be in communication with each other, and is in communication with the nozzle 70; and driving units 80, 90 configured to drive the first syringe 30 and the second syringe 40 such that the first syringe 30 and the second syringe 40 suction and discharge fluid from the nozzle 70 individually or in cooperation with each other.

Abstract: A negative mask unit which can perform exposure from either of reference film or new-type film simply by changing the direction of insertion of the negative film. The negative mask unit has a negative film feed passage provided between a base plate and a top plate. The film feed passage is composed of first to third feed passages. A negative mask is exchangeably set between the first and third feed passages. Two sets of mask-related members necessary to process reference film (135 film) and new-type film, including a film inlet, feed means, and sensors, are provided on one and the other sides of the negative mask, respectively. One of the sets is selected and film is inserted from the side of the selected set for exposure.

Abstract: A photograph processing device includes an automatic negative mask section having a film slot and a cartridge setting unit at the film slot. A guide guides a film separated from a cartridge into the film slot. The guide is removably attached to the cartridge setting unit. The guide is attached to a periphery of the cartridge setting unit by a hinge to be integral therewith.

Abstract: A conveyor belt includes a PET film as a core and an urethane layer formed on a surface of the PET film by screen-printing urethane beads containing ink. This conveyor belt is for use in a belt type photosensitive-material storage section of a photosensitive-material transport apparatus in order to absorb difference in processing capacities of a printing section and a developing section.

Abstract: A photographic processing apparatus having magnetic heads for reading magnetic record data stored in the magnetic recording tracks of a film and writing desired record data onto the same. The apparatus includes a hold-down mechanism for pressing the magnetic head against the film at an appropriate strength.

Abstract: A photographic exposure apparatus has a light path for directing an optical pattern of a display image from an image display to a photosensitive material and a light path for directing an optical pattern of a negative image from a negative film of the photosensitive material. The two light paths are selectively switched from one to the other to project each of the display and negative images onto the photosensitive material at a common exposure station. A mirror is disposed turnably to be movable across and between the two light paths. A mirror drive turns the mirror through a predetermined angle to switch between the light path for projecting the display image and the light path for projecting the negative image.

Abstract: A photographic printing apparatus includes an exposure station disposed in a midway region of a transfer path between a transfer inlet and a transfer outlet along which a negative film having magnetic recording tracks provided thereon is transferred forwardly and backwardly. A magnetic read head disposed between the transfer inlet and the exposure station, the magnetic read head being spaced from a center line of the exposure station by a distance which is equal to a sum of an integer multiple of the pitch length of one frame on the negative film and a half of the same.

Abstract: A negative film masking apparatus for use in printing of a negative film has patterns of latent image data recorded thereon outside of frames and is held between a negative holder and a mask cover for an exposure operation. A view window is provided in one of either of the negative holder and the mask cover to allow each desired one of the latent image patterns of the negative film to be viewed. A light emitter is mounted on the other of the negative holder and the mask cover opposite to the view window.

Abstract: A paper magazine is capable of feeding and rewinding a web of paper automatically without forming any indentation in or causing meandering of the web of paper. A pair of press rollers and a paper detection roller are provided along a feed path extending from the core of a paper roll in a paper magazine case to a paper outlet. A cam plate and an engaging roller control the movement of the press rollers toward and away from each other according to the position of the paper detection roller. The transmission of driving force to the core of the paper roll and the press rollers is changed over according to the position of the paper detection roller. The press rollers are pressed against the paper only when feeding and rewinding the paper.

Abstract: A film feed device for feeding films connected to a leader to a negative carrier one after another. A guide block is provided at a film inlet side of the negative carrier provided along the exposure axis. Film feed units having film passage thereon are provided on the guide block. A feed unit having a pair of pulleys and a timing belt is mounted under the guide block to move the guide block in a direction perpendicular to the feed direction of the films. Ahead of the guide block is provided a cutter device to cut the two films when the rear end of the leader reaches the cutter device. The film aligned with the film inlet of the negative carrier is supplied thereto and printed. Then, by moving the guide block until the other film is aligned with the film inlet of the negative carrier, the other film can be printed.
