Abstract
Abstract A stacking device for film sheets wherein the film sheets after having been exposed in an illuminated area are transmitted over a curved path to the inlet opening of a receiving magazine is particularly characterized by a device rotatably mounted at the inlet opening and driven in synchronism. When the front edge of an exposed film sheet approaches the inlet opening the device moves to the side all film sheets already present in the magazine, so that a free passage into the magazine is provided for the new film sheet.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
In combination with a film-receiving magazine for use with a camera, said magazine having an inlet opening, means shifting exposed film sheets individually through said inlet opening and into said magazine, a rotary member located adjacent said inlet opening and comprising a slide and an angular member having a slot, said slide being slidable in said slot, a shaft having a crank connected with said slide and means rotating said shaft to cause said slide to carry out a combined longitudinal and rotary movement to push aside film sheets located in said magazine when the front edge of a new film sheet approaches said inlet opening.
Claim 2
Dependent Claim
106 words
In combination with a film-receiving magazine for use with a camera, said magazine having an inlet opening, means shifting exposed film sheets individually through said inlet opening and into said magazine, a rotary member located adjacent said inlet opening and comprising a slide and an angular member having a slot, said slide being slidable in said slot, a shaft having a crank connected with said slide and means rotating said shaft to cause said slide to carry out a combined longitudinal and rotary movement to push aside film sheets located in said magazine when the front edge of a new film sheet approaches said inlet opening.
Claim 3
Dependent Claim
42 words
A device in accordance with claim 1, comprising a guide plate extending close to said inlet opening for guiding a film sheet through said inlet opening, said guide plate having an opening receiving said slide when a film sheet is being exposed.
Claim 4
Independent Claim
122 words
A device for stacking film sheets for use with a camera, comprising in combination with a film exposure area, a magazine having an inlet opening, a guide plate having an opening located adjacent said inlet opening, a slide located adjacent said inlet opening and means moving film sheets individually from said exposing area into said magazine and simultaneously actuating said slide to move it during film exposure into the opening of said guide plate to cover said inlet opening and during the approach of an exposed sheet to move it out of the opening of said guide plate into said inlet opening and move aside film sheets already located in the magazine to facilitate passage of said exposed sheet into the magazine.
Claim 5
Independent Claim
122 words
A device for stacking film sheets for use with a camera, comprising in combination with a film exposure area, a magazine having an inlet opening, a guide plate having an opening located adjacent said inlet opening, a slide located adjacent said inlet opening and means moving film sheets individually from said exposing area into said magazine and simultaneously actuating said slide to move it during film exposure into the opening of said guide plate to cover said inlet opening and during the approach of an exposed sheet to move it out of the opening of said guide plate into said inlet opening and move aside film sheets already located in the magazine to facilitate passage of said exposed sheet into the magazine.
Claim 6
Dependent Claim
35 words
A device in accordance with claim 3, wherein said means comprise a rotary cube having a slit, said slide being slidable in said slit, and a driving shaft having a crank connected with said slide.
