A fluid dispenser dispenses a fluid alternately from one of a pair of ports () that are provided on opposite ends of a syringe () by moving a piston () back and forth inside the syringe. A pair of stirrers () are provided in the syringe on opposite axial sides of the piston. The stirrers may each individually rotate on an axis that extends in parallel with the moving direction of the piston. A pair of stirrer driving rings () are mounted on an outer periphery of the syringe in correspondence with the stirrers. Magnets () are embedded in the stirrers and the stirrer driving rings such that the stirrer is rotated by magnetic fields that are generated from the stirrer driving ring, as the stirrer driving ring is rotated by a motor ().

A method and apparatus for disassembling a used lens-fitted photo film unit whose unit body consists of a body base portion, front and rear cover sections removably engaged with the body base portion and with each other, and a label placed around the unit body. Access holes provided through the front and rear cover sections permit accessing internal engaging portions between the cover sections and the body base portion. The label is cut along joints between the front and rear cover sections by laser markers. Holes are pierced through the label to access holes of the unit body. Thereafter, disengaging tools are sequentially inserted into the access holes through the holes of the label, to disengage the internal engaging portions. Then, the front and rear cover sections are sequentially separated from the body base portion without removing the label from the front and rear cover sections.

Method of disassembling lens-fitted photo film unit and disassembling apparatus therefor

A taking lens of a used lens-fitted photo film unit is cleaned according to sequential steps for recycling. A cleaning head is caused to press a loosened cleaning tape against the taking lens. While the cleaning tape is pressed against the taking lens, the cleaning head is moved, to wipe the taking lens with the cleaning tape. Furthermore, before wiping with the cleaning tape, the taking lens may be brushed by rotating the cleaning head back and forth. In a preferred embodiment, a recycling apparatus includes a disassembly line which disassembles the lens-fitted photo film unit after removal of a cassette shell with photo film being exposed. A main body is obtained with at least a cassette shutter closing mechanism for a cassette shutter and a frame counter mechanism. Furthermore, an inspection line inspects operation of the mechanical parts and a cleaning line cleans at least a viewfinder lens.

Lens cleaning apparatus and method and recycling apparatus and method for lens-fitted photo film unit

A lens-fitted photo film unit includes a main body preloaded with photo film. A front cover covers a front of the main body. A rear cover covers a rear of the main body. A retainer mechanism has a retainer claw and a receiver portion engaged with each other, for connecting rear walls of the main body and the rear cover. An opening is formed in the rear cover, for uncovering at least a portion of the retainer claw or the receiver portion. For disassembly, a release claw is inserted into the opening by setting the lens-fitted photo film unit in a cover separating station with the rear cover directed downwards. The release claw is disposed to protrude upwards in the cover separating station. The release claw is shifted relative to the opening, to disengage the retainer claw from the receiver portion by flexing the retainer claw away therefrom. After disengaging the retainer claw from the receiver portion, the main body is moved away from the rear cover.
