Receipt printer for cash registers and the like

Claim 2

A printer for printing data on a paper tape comprising a printing element having printing type thereon, a device having a paper tear-off edge thereon over which a free end of said tape may be torn, means on said device for guiding said tape past said printing type and past said tear-off edge, and means supporting said device for movement towards said printing type, said tape moving said device toward said printing type to press said tape against said printing type upon pulling said free end of said tape against said tear-off edge and toward said printing type whereby to transfer an imprint from said printing type to said tape and to tear said tape along said tear-off edge.

Claim 3

A printer as defined in claim 1 wherein said device comprises a platen, said guiding means guiding said tape along said platen, said device moving said platen to press said tape against said printing type upon said pulling of said free end of said tape toward said printing type.

Claim 4

A printer as defined in claim 2 wherein said printing type extends in a flat plane and said platen extends in a flat plane, said supporting means supporting said device for movement in a path to cause said platen to press said tape against said type in substantially the same plane as said plane of said type.

Claim 5

A printer as defined in claim 3 wherein said supporting means comprises means pivotally supporting said device for movement about an axis extending at least substantially coincident with said plane of said printing type.

Claim 6

A printer as defined in claim 1 wherein said device has an opening therein in line with said printing element, said device forming a platen facing said opening, said supporting means supporting said device to move through a path wherein said opening passes over said printing element whereby said platen is effective to press said tape against said printing type upon said movement of said device toward said printing element.

Claim 7

A printer as defined in claim 1 comprising spring means for retracting said device from said printing element.

Claim 8

A printer as defined in claim 1 wherein said printing element comprises an ink impregnated elastomeric material.

Claim 9

A printer as defined in claim 1 wherein said device comprises a guide member for guiding said tape endwise over said tear-off edge.

Claim 10

A printer as defined in claim 8 wherein said guide member comprises a platen over which said tape is guided, said platen pressing said tape against said printing type upon movement of said device by said tape.

Claim 11

In a receipt printer mechanism for cash registers and the like having a variable data printer, means for operating said data printer, and means for incrementally advancing an elongate paper tape endwise through said data printer as an incident to operation of said operating means; a fixed data printer comprising a printing element having printing type thereon, a paper guide member having means forming a tear-off edge thereon over which a free end of said tape may be torn after said tape passes through said variable data printer, means on said guide member for guiding said tape past said printing type and past said tear-off edge, and means supporting said guide member for movement towards said printing type, said tape moving said guide member to press said tape against said printing type upon pulling said free end of said tape over said tear-off edge and towards said printing type whereby to transfer an imprint from said printing type to said tape and to tear said tape along said tear-off edge.

Claim 12

In a receipt printer mechanism for cash registers and the like having a variable data printer, means for operating said data printer, and means for incrementally advancing an elongate paper tape endwise through said data printer as an incident to operation of said operating means; a fixed data printer comprising a printing element having printing type thereon, a paper guide member having means forming a tear-off edge thereon over which a free end of said tape may be torn after said tape passes through said variable data printer, means on said guide member for guiding said tape past said printing type and past said tear-off edge, and means supporting said guide member for movement towards said printing type, said tape moving said guide member to press said tape against said printing type upon pulling said free end of said tape over said tear-off edge and towards said printing type whereby to transfer an imprint from said printing type to said tape and to tear said tape along said tear-off edge.

Claim 13

A fixed data printer as defined in claim 10 wherein said guide member has an opening therein, and a platen carried by said guide member opposite said opening, said supporting means supporting said guide member for movement in a path wherein said platen is effective to transfer said imprint to said tape.
