Abstract
A transaction-based printer has a sheet drive for forwarding a sheet through a printing station to a cutting station where the sheet is severed from a spool by a rotary cutter. A kicker element is mounted in the cutting station. Movement of the kicker element is coordinated through the cutter drive with that of the rotary cutter so that the severed sheet is kicked into a bin located in the top cover of the printer. The printer can be, for example, an ink-jet, dot matrix, dye sublimation or thermal printer used to print tickets, vouchers, coupons or the like.
Claims20
Apparatus for automatically stacking printed sheets from a printer comprising:
- a first drive for advancing a sheet through said printer in a first direction;
- a kicker element adapted to contact said sheet after printing;
- a second drive operatively associated with said kicker element for advancing said sheet in a second direction opposite said first direction;
- and
- an output bin for collecting said sheet when the sheet is advanced in said second direction.
A method for stacking tickets in a printer, comprising the steps of:
- driving a sheet through said printer in a first direction;
- printing on the sheet;
- momentarily stopping the sheet;
- advancing the sheet in a second direction opposite said first direction after it has been stopped;
- and
- collecting said sheet in an output bin when the sheet is advanced in said second direction.
A printer having a cutting station for severing a sheet from a supply spool, said printer further including:
- a rotary cutter located in the cutting station having a fixed blade and a rotary blade mounted for rotation about a fixed axis;
- reversible drive means for rotating said rotary blade in a first direction between a start of cut position and an end of cut position wherein a sheet is severed from said spool and a second direction between said end of cut position and said start of cut position;
- a kicker element located in the cutting station upon a shaft so that said kicker element rides in contact with a sheet located in said cutting station;
- a one way clutch for mounting said kicker element to said shaft;
- and
- connecting means for coupling said shaft to said reversible drive means so that said kicker element moves freely upon said shaft as the rotating blade of the cutter rotates in said first direction and is locked to the shaft as the rotating blade moves in the second direction whereby the kicker element drives the severed sheet out of the cutting station.
