A main lens 500 and an auxiliary lens 550 are selectively loaded on a lens loading section 601 of a lens moving deck 600. The lens moving deck 600 is movable in a certain direction to selectively set the lens loading section 601 at an exposed position and a retracted position adjacent to each other. A lens storage deck 700 is provided adjacent the retracted position to load the main lens 500 thereon for housing.
摘要:
The present invention relates to a chromone derivative and an aldose reductase inhibitor comprising said compound as efective component, which is represented by the following formula: ##STR1## wherein R.sub.1 and R.sub.2 each represent a lower alkyl group, etc., R.sub.3 represents an oxygen atom, a sulfur atom, etc., R.sub.7 represents a phenyl group substituted or not substituted, etc., and R represents a hydrogen atom or a lower alkoxy group. The present compounds exhibit superior inhititory action on aldose reductase and are useful for the treatment of various complications of diseases in diabetes, such as cataract, retinopathy, keratopathy, nephropathy, and neuropathy.

A simple and compact apparatus for removing film from a film magazine includes a film slot opening/closing mechanism which is operated by a film slot opening/closing lever, and a spool driving shaft which is turned by a spool revolving knob. The apparatus further includes a film releasing mechanism. The mechanism has a structure such that a film releasing jig is inserted into a cartridge loaded with a film magazine through the film outlet slot of the cartridge by operating a film releasing jig lever.. The apparatus is used with a film magazine whose spool shaft has a film engagement claw therein. A hole formed in the tail end of film is engaged with the engagement claw. When the film releasing jig is inserted into the cartridge, the film is disengaged from the engagement claw. The film slot opening/closing lever, spool revolving knob, and film releasing jig lever are operated manually.

A sorting apparatus for sorting a plurality of prints produced by a photographic printer. The apparatus includes a movable table for mounting the prints thereon, and a stopper member disposed on an upper surface of the movable table for coming into contact with the prints mounted on the movable table. The movable table is projectable and retractable relative to the stopper member. With a retracting movement of the movable table relative to the stopper member, the prints mounted on the movable table are caused to come into contact with the stopper member and to be dropped off the table to be sorted.
