Abstract
Abstract A paper feeder for a printer which is adapted for feeding both continuous printing paper and cut sheet printing paper. A second frame which may carry the platen supports the rear end of a first frame which in turn supports the tractor feeder in such a manner that the first frame can be rotated backward from a first position adapted for feeding continuous paper to a second position adapted for making a room for mounting a paper guide to the printer. If the tractor feeder is adapted for pushing continuous paper towards the platen, continuous paper can be kept on the tractor feeder even when the second frame is at its second position.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
157 words
A paper feeder for a printer, said paper feeder comprising a rotatable platen, a roller defining a nip between said platen and roller, a tractor feeder, a first frame supporting the tractor feeder, a second frame attached to said platen, and a detachable paper guide member for feeding cut paper to the platen and including a planar member supported on said second frame, said planar member defining an acute angle between a first surface of said planar member and a horizontal plane, said planar member oriented tangentially to said platen, whereby said detachable paper guide member guides cut sheet paper directly into said nip; said second frame rotatably supporting a first end of the first frame whereby the first frame and tractor feeder are rotatable from a first operative position wherein said tractor feeds continuous paper around the platen to a second inoperative position and thereby permitting the paper guide member to be supported by the printer.
Claim 2
Dependent Claim
157 words
A paper feeder for a printer, said paper feeder comprising a rotatable platen, a roller defining a nip between said platen and roller, a tractor feeder, a first frame supporting the tractor feeder, a second frame attached to said platen, and a detachable paper guide member for feeding cut paper to the platen and including a planar member supported on said second frame, said planar member defining an acute angle between a first surface of said planar member and a horizontal plane, said planar member oriented tangentially to said platen, whereby said detachable paper guide member guides cut sheet paper directly into said nip; said second frame rotatably supporting a first end of the first frame whereby the first frame and tractor feeder are rotatable from a first operative position wherein said tractor feeds continuous paper around the platen to a second inoperative position and thereby permitting the paper guide member to be supported by the printer.
Claim 3
Dependent Claim
61 words
A paper feeder as defined in claim 1, wherein the tractor feeder includes means for pushing continuous paper towards the platen in said first operative position and said first frame rotates substantially away from said platen in said second inoperative position whereby, when the second frame is at its second inoperative position, continuous paper can remain mounted on the tractor feeder.
