Abstract
Abstract A sheet-holding cassette for a copying machine is formed as a box containing a stack of copy sheets. This box is adapted to be held in the machine with the uppermost sheet of the stack engageable with the paper-advance roller of the machine. A slot is provided in the upper wall of this cassette as well as a guide next to this slot and a deflector in back of this slot so that an extra sheet can be slid along the upper wall of the machine and into the cassette to lie at least at its front edge on top of the stack of sheets in the cassette. Thus as the paper-advance roller is reciprocated down onto the stack it will pick up this extra sheet rather than the top sheet of the stack, allowing a copy to be made on a single extra copy sheet without having to reload the machine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
142 words
In combination with a copying machine having a paper-advance element and means for reciprocating said element toward and away from a paper-supply location, a copy-sheet cassette comprising: a box shaped to hold a stack of copy sheets and adapted to be held in said machine at said location with said stack engageable by said paper-advance element; an upper wall on said box extending over said stack, having a smooth upwardly turned surface, and formed with a throughgoing elongated slot opening at said surface; a guide on said upper surface, whereby an extra sheet can be slid on said surface and along said guide toward said slot; and a deflector on said upper wall adjacent said slot and extending upwardly beyond said upper surface, whereby the sheet slid along said upper surface is deflected by said deflector through said slot into said box.
Claim 2
Dependent Claim
142 words
In combination with a copying machine having a paper-advance element and means for reciprocating said element toward and away from a paper-supply location, a copy-sheet cassette comprising: a box shaped to hold a stack of copy sheets and adapted to be held in said machine at said location with said stack engageable by said paper-advance element; an upper wall on said box extending over said stack, having a smooth upwardly turned surface, and formed with a throughgoing elongated slot opening at said surface; a guide on said upper surface, whereby an extra sheet can be slid on said surface and along said guide toward said slot; and a deflector on said upper wall adjacent said slot and extending upwardly beyond said upper surface, whereby the sheet slid along said upper surface is deflected by said deflector through said slot into said box.
Claim 3
Dependent Claim
36 words
The combination defined in claim 1, wherein said box has a front side and a back side and said slot extends generally parallel to and between said sides, said guide extending generally perpendicular to said slot.
Claim 4
Dependent Claim
27 words
The combination defined in claim 2, wherein said deflector extends backwardly toward said back side from said surface and forms an acute angle with said upper surface.
Claim 5
Dependent Claim
17 words
The combination defined in claim 3, wherein said slot has a front edge defined by said deflector.
Claim 6
Dependent Claim
32 words
The combination defined in claim 2, wherein said upper surface carries indicia showing the position for the trailing edge of a sheet of paper being slid along said guide into said slot.
Claim 7
Dependent Claim
17 words
The combination defined in claim 2, wherein said upper wall is a removable cover for said box.
Claim 8
Dependent Claim
36 words
The combination defined in claim 2, wherein said upper wall is formed adjacent said front side with a throughgoing hole and said paper-advance element is engageable through said hole with the uppermost sheet of said stack.
Claim 9
Dependent Claim
19 words
The combination defined in claim 7, wherein said front side of said box is substantially open at said hole.
Claim 10
Dependent Claim
19 words
The combination defined in claim 7, wherein said hole is elongated and parallel to and spaced from said slot.
Claim 11
Dependent Claim
