Abstract
Abstract A stacking device for stacking data carriers, especially multi-sheet forms, either face up or face down by selecting the orientation of a reversible, detachable magazine. The carriers are ejected between symmetrically arranged feed rollers. A pivoting diverter, and moderately spring-biased guides extending between the feed roller shafts, direct an ejected carrier over that feed roller which is on the selected side of the plane of symmetry of the feed rollers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
229 words
A stacking device for data carriers ejected from a printing mechanism, said device comprising a detachable stacking magazine; two feed rollers arranged on respective roller shafts at the underside of said magazine, and defining a symmetry plane; means for selectively mounting said magazine for stacking to a selected side of said plane; and means for diverting an ejected carrier toward said selected side into the magazine, characterized in that said stacking magazine comprises one or more moderately spring-biased guides disposed above and spaced from said rollers, fixed to the magazine, said guides having free ends extending through said symmetry plane and having a distal portion extending below said roller shafts, arranged to divert the ejected data carriers over that roller which is on the selected side of said plane into the stacking magazine, and further characterized in that the device comprises a switching shaft arranged above the feed rollers, extending in said plane of symmetry; a double lever mounted on the switching shaft, a respective arm of the lever projecting into the stacking magazine responsive to the placement of the magazine on the respective side of the symmetry plane; a switch mounted to said device outside the stacking magazine; and means for actuating the switch responsive to pivoting of the double lever in either direction for providing an electrical signal when a magazine has been filled with ejected carriers.
Claim 2
Dependent Claim
229 words
A stacking device for data carriers ejected from a printing mechanism, said device comprising a detachable stacking magazine; two feed rollers arranged on respective roller shafts at the underside of said magazine, and defining a symmetry plane; means for selectively mounting said magazine for stacking to a selected side of said plane; and means for diverting an ejected carrier toward said selected side into the magazine, characterized in that said stacking magazine comprises one or more moderately spring-biased guides disposed above and spaced from said rollers, fixed to the magazine, said guides having free ends extending through said symmetry plane and having a distal portion extending below said roller shafts, arranged to divert the ejected data carriers over that roller which is on the selected side of said plane into the stacking magazine, and further characterized in that the device comprises a switching shaft arranged above the feed rollers, extending in said plane of symmetry; a double lever mounted on the switching shaft, a respective arm of the lever projecting into the stacking magazine responsive to the placement of the magazine on the respective side of the symmetry plane; a switch mounted to said device outside the stacking magazine; and means for actuating the switch responsive to pivoting of the double lever in either direction for providing an electrical signal when a magazine has been filled with ejected carriers.
Claim 3
Dependent Claim
41 words
A device as claimed in claim 1, characterized in that the bottom of the stacking magazine has at least one opening, the feed roller on the selected side of said plane of symmetry projecting partly into said at least one opening.
Claim 4
Dependent Claim
50 words
A device as claimed in claim 2, characterized in that the stacking magazine further includes a plate for defining the position of the bottom of a stack of ejected carriers, said plate being pivotally connected in the magazine and having a spring biasing said plate toward the nearer feed roller.
Claim 5
Dependent Claim
82 words
A device as claimed in claim 1, characterized in that a second double lever is mounted on said switching shaft for pivotal movement about the switching shaft, said second lever being disposed within the magazine which is mounted by the mounting means, said second lever being engaged by a portion of said magazine so as to pivot the lever to a direction in which the lever engages and diverts a carrier being ejected toward the selected side of said plane of symmetry.
Claim 6
Dependent Claim
151 words
A stacking device for data carriers ejected from a printing mechanism, said device comprising a detachable stacking magazine; two feed rollers arranged on respective roller shafts at the underside of said magazine, and defining a symmetry plane; means for mounting said magazine for stacking to a selected side of said plane; and means for diverting an ejected carrier toward said selected side into the magazine, characterized in that said device includes a side wall and a diverter lever pivotally mounted to the side wall about a pivot axis lying in said plane of symmetry above the feed rollers, said diverter lever extending into the stacking magazine and arranged so that placing of the magazine pivots the lever by engagement of the lever with a magazine wall, such that an ejected carrier is diverted over that roller which is on the selected side of said plane of symmetry into the stacking magazine.
Claim 7
Dependent Claim
151 words
A stacking device for data carriers ejected from a printing mechanism, said device comprising a detachable stacking magazine; two feed rollers arranged on respective roller shafts at the underside of said magazine, and defining a symmetry plane; means for mounting said magazine for stacking to a selected side of said plane; and means for diverting an ejected carrier toward said selected side into the magazine, characterized in that said device includes a side wall and a diverter lever pivotally mounted to the side wall about a pivot axis lying in said plane of symmetry above the feed rollers, said diverter lever extending into the stacking magazine and arranged so that placing of the magazine pivots the lever by engagement of the lever with a magazine wall, such that an ejected carrier is diverted over that roller which is on the selected side of said plane of symmetry into the stacking magazine.
Claim 8
Dependent Claim
41 words
A device as claimed in claim 5, characterized in that the bottom of the stacking magazine has at least one opening, the feed roller on the selected side of said plane of symmetry projecting partly into said at least one opening.
Claim 9
Dependent Claim
50 words
A device as claimed in claim 6, characterized in that the stacking magazine further includes a plate for defining the position of the bottom of a stack of ejected carriers, said plate being pivotally connected in the magazine and having a spring biasing said plate toward the nearer feed roller.
