Claim 6

The improved printer of claim 3 further comprising paper guide means positioned opposite a portion of the print roller for guiding sheets of paper to said gap between the paper guide and print roller whereby sheets of paper can be fed past the print element from two sources.

Claim 7

The paper tray of claim 3 wherein said connection of said paper receiving means is pivotable such that controllable access is provided to said paper guide means.

Claim 8

In a printer having a print roller, a print element opposite the print roller and a paper guide for guiding a sheet of paper between the print element and print roller, the improvement comprising: an output roller opposite the print roller and located past the print element; unitary paper feed storage and paper collector means for feeding sheets of paper to a gap between the paper guide and the print roller and for stacking paper delivered by rotation of the print and output rollers, paper guide means positioned opposite a portion of the print roller for guiding sheets of paper to said gap between the paper guide and print roller whereby sheets of paper can be fed past the print element from two sources, said unitary paper feed storage and paper collector means including a paper receiver means pivotably supported with respect to the remainder of the unitary paper feed storage and paper collector means for movement between a first position in which sheets of paper can be fed from the unitary paper feed storage as a first of said sources to the print roller and print element via said paper guide and a second position in which sheets of paper can be fed from the second of said sources to the print roller and print element via said paper guide means.

Claim 9

In a printer having a print roller, a print element opposite the print roller and a paper guide for guiding a sheet of paper between the print element and print roller, the improvement comprising: an output roller opposite the print roller and located past the print element; unitary paper feed storage and paper collector means for feeding sheets of paper to a gap between the paper guide and the print roller and for stacking paper delivered by rotation of the print and output rollers, paper guide means positioned opposite a portion of the print roller for guiding sheets of paper to said gap between the paper guide and print roller whereby sheets of paper can be fed past the print element from two sources, said unitary paper feed storage and paper collector means including a paper receiver means pivotably supported with respect to the remainder of the unitary paper feed storage and paper collector means for movement between a first position in which sheets of paper can be fed from the unitary paper feed storage as a first of said sources to the print roller and print element via said paper guide and a second position in which sheets of paper can be fed from the second of said sources to the print roller and print element via said paper guide means.

Claim 10
