Abstract
Abstract A developer solution supplying device is made independently of the camera body and integrally fixed to a spool for feeding out a positive image forming paper. The unit of the solution supplier and the posi-paper spool is demountably attached to the camera body. The developer solution supplying device is operable from outside the camera by operating two manual operating members. The posi-paper is provided with a number of solution containers for the respective images which are filled one by one with the developer solution as the paper advances by pulling the paper with the negative film out of the camera.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
197 words
A photographic apparatus having a built-in processor of the diffusion transfer type comprising: a first piston cylinder for supplying a developer solution in which a piston is normally urged in the direction for supplying the solution, said piston being movable from its normally urged position to a retracted position; a second piston cylinder for injecting said developer solution, one end of which piston cylinder is opened into a passage for an image forming sheet material, said second piston cylinder containing a piston which is normally urged to close said second piston cylinder but which is movable from its normally urged position to a retracted position; said first and second piston cylinders being provided in a block member which is fixed to a spool for winding said image forming sheet material; a developer solution vessel provided in said spool and demountably mounted to said block member; and a check valve operable in response to the operation of said first piston cylinder and located between said first piston cylinder and said solution vessel, whereby a prescribed amount of said solution is applied to said image forming sheet material by an operation of said piston cylinders from outside the apparatus.
Claim 2
Dependent Claim
197 words
A photographic apparatus having a built-in processor of the diffusion transfer type comprising: a first piston cylinder for supplying a developer solution in which a piston is normally urged in the direction for supplying the solution, said piston being movable from its normally urged position to a retracted position; a second piston cylinder for injecting said developer solution, one end of which piston cylinder is opened into a passage for an image forming sheet material, said second piston cylinder containing a piston which is normally urged to close said second piston cylinder but which is movable from its normally urged position to a retracted position; said first and second piston cylinders being provided in a block member which is fixed to a spool for winding said image forming sheet material; a developer solution vessel provided in said spool and demountably mounted to said block member; and a check valve operable in response to the operation of said first piston cylinder and located between said first piston cylinder and said solution vessel, whereby a prescribed amount of said solution is applied to said image forming sheet material by an operation of said piston cylinders from outside the apparatus.
Claim 3
Dependent Claim
104 words
A photographic apparatus having a built--in processor as defined in claim 1 wherein said first piston cylinder is provided with a first manual operating member for moving the piston therein from its normally urged position to its retracted position, said second piston cylinder is provided with a second manual operating member for moving the piston therein to its retracted position, and said first manual operating member and said second manual operating member are corelated with each other so that the manual operation of said second manual operating member makes said first manual operating member return To its normally urged position from its retracted position.
Claim 4
Dependent Claim
36 words
A photographic apparatus as defined in claim 2 wherein said first manual operating member and said second manual operating member are corelated with each other by means of a lever pivotally mounted on said block member.
Claim 5
Dependent Claim
26 words
A photographic apparatus as defined in claim 3 wherein said second manual operating member is urged to its normal position to close said second piston cylinder.
Claim 6
Dependent Claim
43 words
A photographic apparatus as defined in claim 4 wherein said lever has a means for holding said first manual operating member in its retracted position while keeping said second manual operating member in its normal position to keep said second piston cylinder closed.
Claim 7
Dependent Claim
49 words
A photographic apparatus as defined in claim 5 wherein said lever is rotated to release said first manual operating member from its manually brought position by manually operating said second manual operating member, whereby the solution is forced out of said first piston cylinder into said second piston cylinder.
Claim 8
Dependent Claim
96 words
A photographic apparatus as defined in claim 1 wherein said first piston cylinder is located in a portion of said block member which is nearer to the top of said photographic apparatus as said photographic apparatus is positioned during normal use than the portion of said photographic apparatus in which said second piston cylinder is located, said first and second piston cylinders are disposed horizontally as said photographic apparatus is disposed during normal use, and said second piston cylinder is located substantially at a level half of the height of the image forming material passing thereby.
