Abstract: There is disclosed an electronic imaging device having an imaging element, a mechanism which removes dust attached to the imaging element or an optical element disposed in front of the imaging element, and a display section which displays that at least the mechanism is operating. Consequently, an operator of the electronic imaging device can exactly recognize whether or not the mechanism to remove the dust is operating. Examples of the mechanism which removes the dust include an excitation mechanism which vibrates a dustproof filter disposed in front of the imaging element, a mechanism which removes the dust by a gas flow and the like.

Abstract: In a shutter facing an aperture portion in a partition plate in a photosensitive material processing device, a blocking member, formed substantially in a semicircular cylindrical shape, is placed by the rotation of a shaft between blades thereby closing the aperture portion. The opening between the blades is opened by rotating the blocking member integrally with the shaft so that a photosensitive material can pass through. Multi-leveled surfaces are formed on the top surface of a guide plate. Aperture portions for mounting rollers with adaptors are formed in an alternating pattern on the surfaces. A plurality of protruding guide ribs are provided extending across the surfaces. A plurality of brush roller parameters are adjusted so that a winding mark index defined by the parameters falls within a predetermined range. Rollers are washed when a finisher control system is restarted after an unforeseen long stoppage.

Abstract: A photographic processor and a method of operation is disclosed. The processor is in the form of a circular drum processor into which photographic film is inserted and processed. The processor includes a washing assembly which is adapted to wash the non-emulsion surface of the film and other components of the processor as the processed film is removed from the processor.

Abstract: There is provided an automatic processing machine which comprises a processing-solution processing section in which a photographic photosensitive material is subjected to development processing, and a drying section for drying the photeosensitive material processed in the processing-solution processing section, particularly, an automatic processing machine in which an upper roller of conveying rollers or squeeze rollers, which are disposed at an upstream side of the drying section, is formed so that a contact angle of a water drop on a peripheral surface thereof is less than 135°, preferably 125°. The upper roller of silicone rubber in the conveying rollers or in the squeeze rollers includes a peripheral surface coated with a gelatin film. By conducting cross-linking using silicon for a long duration at the time of manufacturing silicone rubber, water repellency of the surface (that is, surface tension) is restrained and the contact angle of a water drop is thereby set to be less than 135°.

Abstract: When gears which drive rollers for transporting photographic printing paper are rotated to thereby transport the photographic printing paper, shutters retract from a photographic printing paper passage and rollers rotate so that the photographic printing paper is transported. When the gears are reversed after the completion of the transport of the photographic printing paper, the shutters block the photographic printing paper passage and are located above the rollers which protrude in the photographic printing paper passage to thereby prevent floating materials such as silver, sulfide, soiling and the like from precipitating on the surfaces of the rollers.

Abstract: As developing processing operation is completed, driving of a motor is stopped so that rotation of conveying rollers is stopped. Then, in association with stopping of the conveying rollers, a timer is started. At a time when the timer has counted a specified amount of time, a controller rotates the conveying rollers for a predetermined amount of time, and then stops rotation thereof. When the rotation of the conveying rollers is stopped, the timer is reset and is restarted. Above operations are repeated intermittently at the time when the timer has counted the specified amount of time. Alternatively, the timer may be started when power of a photosensitive material processing apparatus is turned off. Further, the timer may be started in association with a predetermined control (such as preheating) for the photosensitive material processing apparatus.

Abstract: A transport unit of an intraoral dental x-ray developing machine includes a track and upper and lower transfer drives for moving film chips through tanks of developing, fixing and rinsing solutions. Transfer grooves in the track can become clogged with debris during normal operation of the x-ray developing machine. Projections extending from transfer arms of the lower transfer drive are provided to clean the debris from the grooves.

Abstract: Disclosed herein is an apparatus for cleaning residue from a transport unit of an x-ray developing machine. The transport unit has inner and outer walls which form a path for multiple film chips to travel during development of the film chips. V-grooves in the walls can become clogged with residue during normal operation of the x-ray developing machine. The apparatus includes a body and a plurality of projections extending outward from the body. The projections clear the V-grooves of residue while the apparatus is inserted between the walls and moved along the path.

Abstract: A photographic sheet material processing apparatus has a plurality of treatment cells (12', 12", 12'") mounted one above another in a vertical stack to define a substantially vertical sheet material path (20) through the apparatus. The apparatus is cleaned by feeding a cleaning liquid to a first cell (12'), allowing at least a portion of said cleaning liquid to pass by gravity from said first cell (12') to at least one further cell (12"), and discharging said cleaning liquid from the apparatus. This process provides a convenient and efficient method of cleaning a vertical photographic sheet material processing apparatus.

Abstract: A system and method for exchanging an old software version for a new version within a telecommunications switch without a system restart. The switch includes memory, a software loading subsystem, a database management subsystem, and a program exchange subsystem. The new software version is exchanged for the old software version by loading the new software version into the memory of the switch using the software loading subsystem. The new software version is then registered in the program exchange subsystem using the database management subsystem. The old software version is passivated, and the new software version is activated using the program exchange subsystem, thereby, exchanging the old software version for the new software version.

Abstract: A cleaning structure for an out-of-liquid conveying portion whose object is to facilitate detachment and attachment of a cleaning nozzle unit from and to a crossover rack, and to hold cleaning nozzles in predetermined positions suitable for the out-of-liquid conveying portion in a state in which the cleaning nozzle unit has been mounted to the crossover rack. In order to mount the cleaning nozzle unit to the crossover rack, the cleaning nozzles are made to penetrate through through-holes defined in one of side walls of the crossover rack. In this state, an interlocking member is elastically flexed so as to be inserted into an interlocking hole. After completion of its insertion of the interlocking member, a hook is brought into engagement with an upper edge of the interlocking hole by elastic recovery of the interlocking member. As a result, a case can be mounted to the side wall.

Abstract: A condensation preventing structure for a crossover rack provided in a printer processor. The structure has a plurality of conveying rollers provided at a crossover rack provided within a printer processor, and a moisture adhesion prevention/moisture removing device which effects one of prevention of adhesion of moisture to the plurality of conveying rollers due to condensation and removal of moisture on the plurality of conveying rollers due to condensation. Due to the moisture adhesion prevention/moisture removing device, uneven development of a photographic printing paper caused by moisture adhering to the plurality of conveying rollers due to condensation does not occur.
