Abstract

Abstract A self-developing slide copier or printer configured to be supported on a support surface and operable for effecting distribution of a fluid processing composition between sheets of a self-developing film unit in response to manually withdrawing or pulling the film unit along a preferred exit path has its film receiving housing set at a predetermined angle on a support frame so that the preferred exit path will fall within a range of natural pull paths along which an operator most likely will pull the film unit to withdraw it from the housing. The printer is also provided with multiple timers for separately timing a predetermined imbibition period for each of a plurality of sequentially processed film units.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 176 words
Photographic apparatus configured to be supported on a substantially horizontal support surface at approximately table top height and operable for effecting distribution of a fluid processing composition over an area of a self-developing film unit in response to manually pulling the film unit out of said apparatus, said apparatus comprising: a housing for receiving such a film unit and having a film withdrawal opening through which the film unit is pulled along a preferred exit path, exteriorly of said housing, to optimize fluid distribution; and means for supporting said apparatus on the support surface with said housing arranged thereon so that said preferred exit path is inclined upwardly and away from the support surface in the direction of film pull and is within a range of natural pull paths along which an operator most likely will pull the film unit and including shallow angle pull paths resulting from the operator being in a sitting position relative to the support surface and steeper angle pull paths resulting from the operator being in a standing position relative thereto.
Claim 2
Dependent Claim 176 words
Photographic apparatus configured to be supported on a substantially horizontal support surface at approximately table top height and operable for effecting distribution of a fluid processing composition over an area of a self-developing film unit in response to manually pulling the film unit out of said apparatus, said apparatus comprising: a housing for receiving such a film unit and having a film withdrawal opening through which the film unit is pulled along a preferred exit path, exteriorly of said housing, to optimize fluid distribution; and means for supporting said apparatus on the support surface with said housing arranged thereon so that said preferred exit path is inclined upwardly and away from the support surface in the direction of film pull and is within a range of natural pull paths along which an operator most likely will pull the film unit and including shallow angle pull paths resulting from the operator being in a sitting position relative to the support surface and steeper angle pull paths resulting from the operator being in a standing position relative thereto.
Claim 3
Dependent Claim 58 words
The apparatus of claim 1 wherein said range of natural pull paths falls within angles of approximately 8 to 20 degrees with respect to the horizontal support surface and said housing is arranged on said supporting means so that said exit path is inclined at an angle of approximately 10 degrees with respect to the horizontal support surface.
Claim 4
Dependent Claim 81 words
The apparatus of claim 1 wherein said film withdrawal opening is at one end of said housing, said apparatus further includes means for locating the film unit at a film plane with said housing, said preferred exit path is substantially parallel to said film plane and said housing is inclined with respect to the support surface so that said end of said housing having said withdrawal opening is further away from the support surface than an opposite end of said housing.
Claim 5
Dependent Claim 105 words
The apparatus of claim 1 wherein said housing includes an upper section and a lower section movable relative to said upper section between open and closed positions, said support means includes first support means for supporting said apparatus at an operative position wherein said housing for receiving the film unit is adjacent the support surface and second support means for supporting said apparatus at an inoperative position for presenting said housing at a location further away from said support surface when said lower housing section is in said closed position to provide better access to said housing and facilitate loading film units into said housing.
Claim 6
Dependent Claim 37 words
The apparatus of claim 4 wherein said first supporting means is located on a bottom portion of apparatus and said second supporting means is on a rear portion thereof in approximately perpendicular relation to said bottom portion.
Claim 7
Dependent Claim 41 words
The apparatus of claim 5 wherein said bottom and rear portion intersect at a corner of said apparatus and said corner is rounded for engaging the support surface to facilitate manual rotation of said apparatus between said operative and inoperative positions.
Claim 8
Dependent Claim 66 words
The apparatus of claim 6 wherein said apparatus further includes an electrical system having a power cord for connecting said system to a source of electrical power and said apparatus further includes an apparatus housing section having a recess for receiving and storing said cord in a manner allowing manual movement of said apparatus between said operative and inoperative positions without interference from said power cord.
