Abstract
Abstract A bath container and a main body case having the container therein are joined together at a level higher than the liquid level within the container, with spaces formed between the container and the main body case for accommodating a power transmission assembly and providing a duct for passing hot air therethrough. A rack frame supporting many pairs of feed rollers and detachably installed in the container has eave-like shield pieces serving as safety covers and light blocking plates.

Claim 1
Independent Claim
253 words
An apparatus for automatically developing a film by passing the film through a bath, said apparatus comprising: a container for the bath having upwardly extending side and end walls; a main body within which said container is positioned, said main body having upwardly extending side and end walls spaced from the side and end walls of said container to define spaces therebetween, the upper ends of said side and end walls being integrally joined together to close the upper end of said spaces; said container having a bottom positioned above the bottom of said side and end walls of said main body to define a bottom space thereunder and which is joined to said space between said side and end walls; a feed roller assembly removably mounted in said container; a power transmission assembly in one of said spaces and detachably connected to said feed roller assembly; a drive motor in one of said spaces connected to said power transmission assembly for driving said power transmission assembly; said container end wall and side walls having openings therein at the delivery end of said feed roller assembly and opening out of the upper ends of the spaces between said side walls and end walls; and a drying blower in one of said spaces and having a hot air discharge directed toward said spaces between said container and main body side and end walls for directing hot air upwardly therethrough and out of said openings for drying film being discharged by said feed roller assembly.

An apparatus for automatically developing a film by passing the film through a bath, said apparatus comprising: a container for the bath having upwardly extending side and end walls; a main body within which said container is positioned, said main body having upwardly extending side and end walls spaced from the side and end walls of said container to define spaces therebetween, the upper ends of said side and end walls being integrally joined together to close the upper end of said spaces; said container having a bottom positioned above the bottom of said side and end walls of said main body to define a bottom space thereunder and which is joined to said space between said side and end walls; a feed roller assembly removably mounted in said container; a power transmission assembly in one of said spaces and detachably connected to said feed roller assembly; a drive motor in one of said spaces connected to said power transmission assembly for driving said power transmission assembly; said container end wall and side walls having openings therein at the delivery end of said feed roller assembly and opening out of the upper ends of the spaces between said side walls and end walls; and a drying blower in one of said spaces and having a hot air discharge directed toward said spaces between said container and main body side and end walls for directing hot air upwardly therethrough and out of said openings for drying film being discharged by said feed roller assembly.
Claim 3
Dependent Claim
99 words
An apparatus as claimed in claim 1 in which said feed roller assembly includes a frame having upwardly extending side plates, the rollers of said assembly being mounted across the space between said side plates, and laterally extending shield pieces on the upper edges of said side plates, and said side walls of said container having step portions therein on which the outer ends of said shield pieces rest for supporting said feed roller assembly in said container, said shield pieces covering the upper ends of the spaces between said side plates and the side walls of said container.
