Abstract
A statement printer of an automated teller machine includes a top plate (16) pivotally mounted on a pair of spaced side walls (12). The top plate supports a ribbon cartridge (18) thereon. The cartridge includes a pair of downward extending projections (38) which are accepted in a longitudinally extending recess (24) in the top plate. Notches (40) and the longitudinally extending projections engage a leaf spring (28) to position the cartridge thereon. The top plate further includes a pair of finger projections (30) having slots (34) for accepting wing projections (36) that extend from the sides of the cartridge. The guided relationship between the downward extending projections and wing projections on the cartridge and the longitudinal recess and the slots on the top plate enable the cartridge to be guided into position on and off the top plate which facilitates changing the cartridge in the confined space inside an automated teller machine.

3. A printer cartridge adapted for use in an environment including a printer having a support plate, the cartridge configured to be detachably mountable on the support plate of the printer, said support plate including a recess extending generally inward in a first surface of the support plate and wherein the recess is elongated in generally a first direction, and wherein said support plate is in supporting connection with a generally outward extending leaf spring, said cartridge comprising:
at least one extending projection, wherein said extending projection extends generally outward in a first projecting direction on the cartridge and in a longitudinal direction generally perpendicular to the first projecting direction, and wherein the extending projection is configured to be accepted in said recess in generally close fitting relation, wherein when the extending projection is accepted in the recess said extending projection of said cartridge is aligned with the recess on said support plate and extends generally in the first direction, and wherein the extending projection includes at least one notch, wherein the notch is configured such that when the extending projection is accepted in the recess the notch accepts the leaf spring therein. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A printer mechanism comprising:
-
a replaceable print cartridge having a ribbon, said cartridge including a first projection and a second projection, wherein the first projection extends generally perpendicular to the second projection, a support means for supporting said cartridge, said cartridge support means including a recess accepting said first projection and a slot for accepting said second projection; a plurality of aligned engaging pairs of paper feed rolls, at least one of the rolls in each pair including a circumferential flat spot; a print head for printing on said adjacent paper by impacts with said ribbon, and a guide block, said print head mounted on said guide block, said guide block movably mounted on a guide, said guide block having a cutter movably mounted thereon, a lever operatively connected to said cutter, said printer further comprising lever stops engageable with said lever at opposed extremes of travel of said guide block on said guide, wherein engagement of said lever with a first of said lever stops moves said cutter from a non-cutting to a cutting condition, and wherein engagement of said lever with the other of said lever stops moves said cutter from a cutting to a non-cutting condition; a paper tray supporting a stack of said paper thereon, a spring member biasing said paper tray against the weight of said stack and a switch means for generating a signal when said paper tray is moved by the biasing force of said spring member; and impact signal generating means in connection with said print head for generating impact signals causing said print head to impact said ribbon, counting means for counting said impacts, said counting means in interconnected relation with said signal generating means wherein said impact signals are modified responsive to an increase in the count of said impacts to increase an impact force of said print head with said ribbon.

21. A printer mechanism comprising:
-
a frame; a support plate supported on said frame; a print cartridge; wherein one of either said support plate or said print cartridge includes a first projection and the other of the support plate or the print cartridge includes a first recess, wherein the first projection is accepted in nested relation in the first recess when the printer cartridge is in a mounted position on the support plate, and wherein one of either the support plate or the print cartridge includes a second projection, wherein the second projection extends generally perpendicular to the first projection when the print cartridge is in the mounted position, and wherein the other of the support plate or the print cartridge includes a second recess, wherein the second recess accepts the second projection therein in nested relation when the print cartridge is in the mounted position. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
