Abstract
Abstract A low-cost finisher that creates stapled books includes a tray that is tilted at an acute angle backward and away from the direction of incoming copy sheets. Copy sheets are fed into and slide down the copy sheet support surface of the tray and against a rear registration wall of the tray under the influence of tampers. Another tamper forces the copy sheets against a side registration guide of the tray to align them in the head of a stapler. Stapled books are transported out of the tray to a catch tray.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
213 words
A finishing apparatus adapted to staple and transport compiled sheets therefrom, comprising: a tray positioned to receive copy sheets on a support surface thereof, said tray being tilted backwards at an acute angle in a downhill configuration with respect to the sheet feeding direction, skewed corrugation rolls positioned above and adapted to feed copy sheets into said tray, a plurality of resiliently biasable lead edge tamper members adapted to contact the lead edges of the copy sheets individually and be propelled by the sheets in the direction of movement of the sheets as the sheets enter said tray and subsequently drive the sheets in reverse to the sheet feed direction against a rear registration wall of said tray, stapler means positioned adjacent a corner of said tray formed by the intersection of said support surface and said rear wall for stapling the copy sheets, side tamper means for shifting each sheet individually into said stapler means so that a complete set of copy sheets can be stapled by said stapler means, and wherein said tray means includes drive means adapted to drive the stapled set of copy sheet out of said tray while the first sheet of the next set of copy sheet is being feed into said tray by said corrugation rolls.
Claim 2
Dependent Claim
213 words
A finishing apparatus adapted to staple and transport compiled sheets therefrom, comprising: a tray positioned to receive copy sheets on a support surface thereof, said tray being tilted backwards at an acute angle in a downhill configuration with respect to the sheet feeding direction, skewed corrugation rolls positioned above and adapted to feed copy sheets into said tray, a plurality of resiliently biasable lead edge tamper members adapted to contact the lead edges of the copy sheets individually and be propelled by the sheets in the direction of movement of the sheets as the sheets enter said tray and subsequently drive the sheets in reverse to the sheet feed direction against a rear registration wall of said tray, stapler means positioned adjacent a corner of said tray formed by the intersection of said support surface and said rear wall for stapling the copy sheets, side tamper means for shifting each sheet individually into said stapler means so that a complete set of copy sheets can be stapled by said stapler means, and wherein said tray means includes drive means adapted to drive the stapled set of copy sheet out of said tray while the first sheet of the next set of copy sheet is being feed into said tray by said corrugation rolls.
Claim 3
Dependent Claim
24 words

Claim 4
Dependent Claim
30 words
The finishing apparatus of claim 2, wherein said wire means are mounted on a shaft that support said drive means which transports stapled copy sheet sets away from said tray.
Claim 5
Dependent Claim
48 words
The finisher apparatus of claim 3, wherein said drive means which transports stapled copy sheet sets out of said tray includes drive rolls and idler rolls surrounded by belt means with said belt means being positioned within but slightly above the copy sheet support surface of said tray.
Claim 6
Dependent Claim
213 words
A finishing apparatus adapted to staple and transport compiled sheets therefrom, comprising: a tray positioned to receive copy sheets on a support surface thereof, said tray being tilted backwards at an acute angle in a downhill configuration with respect to the sheet feeding direction, skewed corrugation rolls positioned above and adapted to feed copy sheets into said tray, lead edge tamper means adapted to contact the lead edges of the copy sheets individually and be propelled by the sheets in the direction of movement of the sheets as the sheets enter said tray and subsequently the spring bias of said lead edge tamper means drives the sheets in reverse to the sheet feed direction against a rear registration wall of said tray, stapler means positioned adjacent a corner of said tray formed by the intersection of said support surface and said rear wall, side tamper means adapted to shift each sheet individually into said stapler means so that a complete set of copy sheets can be stapled by said stapler means, and wherein said tray means includes drive means adapted to drive the stapled set of copy sheet out of said tray while the first sheet of the next set of copy sheet is being feed into said tray by said corrugation rolls.
