Abstract
Abstract An apparatus for developing a photographed film comprises a turn table on which processing liquid cups are mounted, a rotary device for rotating the film to be developed, and a device for descending and ascending the rotary device into and out of the liquid cups, respectively. The rotary device is formed separately from the descending and ascending device but is detachably supported thereon. The rotary device comprises a housing, a small motor contained in the housing with an output shaft thereof connected to an outwardly projecting rotary member, and a cylindrical holder for detachably holding the housing thereon, the holder having a hollow space adapted to snugly contain a magazine of the film which has a rotary spool engageable with the rotary member projecting from the housing.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
273 words
An apparatus for developing a photographed film roll by rotating the roll in a liquid developer, said apparatus comprising: a case body; a liquid chamber mounted on said case body; a turn table rotatably mounted on said case body above said liquid chamber; processing liquid cup-shaped containers detachably mounted on said turn table and downwardly projecting into said liquid chamber; a cassette or magazine for housing a photographed film roll having a liquid permeable structure; means for descending and ascending said cassette or magazine into and out of said containers, said means comprising: a vertical shaft movable in the vertical direction and extending through said case body, and a horizontal arm extending above said turn table and connected to said vertical shaft; means for rotating a photographed film roll in one and then the other direction, said means comprising: a housing adapted to contain a motor, a motor positioned in said housing and having an output shaft, a rotary member connected to said output shaft and outwardly projected through said housing, and a cylindrical holder detachably holding said housing, said holder having a peripheral wall including a flange portion detachably holding said cylindrical holder on said horizontal arm, and a hollow space surrounded by said wall and snugly containing said cassette or magazine; and a rotary spool projecting into said cassette or magazine and rotatably connected thereto, said spool having one end connected to said rotary member and another end connected to a photographed film roll whereby when said motor imparts a rotational movement to said rotary member through said output shaft said spool imparts a corresponding rotational movement to a film roll.
Claim 2
Independent Claim
273 words
An apparatus for developing a photographed film roll by rotating the roll in a liquid developer, said apparatus comprising: a case body; a liquid chamber mounted on said case body; a turn table rotatably mounted on said case body above said liquid chamber; processing liquid cup-shaped containers detachably mounted on said turn table and downwardly projecting into said liquid chamber; a cassette or magazine for housing a photographed film roll having a liquid permeable structure; means for descending and ascending said cassette or magazine into and out of said containers, said means comprising: a vertical shaft movable in the vertical direction and extending through said case body, and a horizontal arm extending above said turn table and connected to said vertical shaft; means for rotating a photographed film roll in one and then the other direction, said means comprising: a housing adapted to contain a motor, a motor positioned in said housing and having an output shaft, a rotary member connected to said output shaft and outwardly projected through said housing, and a cylindrical holder detachably holding said housing, said holder having a peripheral wall including a flange portion detachably holding said cylindrical holder on said horizontal arm, and a hollow space surrounded by said wall and snugly containing said cassette or magazine; and a rotary spool projecting into said cassette or magazine and rotatably connected thereto, said spool having one end connected to said rotary member and another end connected to a photographed film roll whereby when said motor imparts a rotational movement to said rotary member through said output shaft said spool imparts a corresponding rotational movement to a film roll.
Claim 3
Dependent Claim
36 words
An apparatus as claimed in claim 1, wherein said peripheral wall has an opening therethrough to enable processing liquid contained in said cup-shaped containers to communicate with said magazine or cassette contained in said hollow space.
Claim 4
Dependent Claim
40 words
An apparatus as claimed in claim 1, wherein said rotating means includes a detector positioned in said housing for detecting the number of revolutions of said motor and supplying an electric signal for reversing the rotational direction of said motor.
Claim 5
Dependent Claim
25 words
An apparatus as claimed in claim 1, wherein said horizontal arm has forked semi-circular ends upon which said flange portion on said cylindrical holder rests.
