71 words
In a strip printer including a rotatable non-advancing print wheel, lateral support means for supporting a strip on edge and strip advancing means, an auxiliary elevation apparatus for printing at various levels on a single document comprising: means cooperating with said lateral support means, and said advancing means for aligning the horizontal position of said document, and means for selectively supporting said document at different heights within said lateral support means.
Claim 2
Dependent Claim
71 words
In a strip printer including a rotatable non-advancing print wheel, lateral support means for supporting a strip on edge and strip advancing means, an auxiliary elevation apparatus for printing at various levels on a single document comprising: means cooperating with said lateral support means, and said advancing means for aligning the horizontal position of said document, and means for selectively supporting said document at different heights within said lateral support means.
Claim 3
Dependent Claim
45 words
The apparatus of claim 1 wherein said means for selectively supporting said document includes: at least one rotatably mounted generally arcuate cam having a plurality of steps, and means for rotating said cam for sequentially presenting said steps to the bottom edge of said document.
Claim 4
Dependent Claim
18 words
The apparatus of claim 2 including: two rotatably mounted generally arcuate cams having a like plurality of steps.
Claim 5
Dependent Claim
33 words
The apparatus of claim 2 wherein said aligning means includes: means for retracting said advancing means from engagement with said document and for simultaneously moving an indexing member across said lateral support means.
Claim 6
Dependent Claim
29 words
The apparatus of claim 4 wherein said aligning means further includes: means for removing said indexing member from said lateral support means as said advancing means engages said document.
Claim 7
Dependent Claim
95 words
In a printer having a print station for printing on a vertically oriented print medium, an apparatus for supporting the print medium at different heights for printing at different levels thereon comprising: stationary means for supporting said print medium at said print station and having means for guiding longitudinal and vertical movement of said print medium within the stationary means, and at least one auxiliary support member having a series of ascending steps positioned thereon, said auxiliary support member being pivotally mounted for presenting a selected step to the lower edge of said print medium.
Claim 8
Dependent Claim
95 words
In a printer having a print station for printing on a vertically oriented print medium, an apparatus for supporting the print medium at different heights for printing at different levels thereon comprising: stationary means for supporting said print medium at said print station and having means for guiding longitudinal and vertical movement of said print medium within the stationary means, and at least one auxiliary support member having a series of ascending steps positioned thereon, said auxiliary support member being pivotally mounted for presenting a selected step to the lower edge of said print medium.
Claim 9
Dependent Claim
38 words
The apparatus of claim 6 wherein said at least one auxiliary support member is a pair of like support members pivotally mounted for simultaneous movement and wherein said series of ascending steps is arcuately positioned on each member.
Claim 10
Dependent Claim
56 words
The apparatus of claim 6 including means for advancing said print medium through said print station, ancillary means for aligning the leading edge of a print medium at the print station and mutually exclusive means cooperating between said advancing means and said ancillary aligning means for disengaging said advancing means when said aligning means is actuated.
