An imprinter having a roller platen assembly movably mounted on a head member for imprinting data from a printing plate such as a credit card onto a form positioned over the plate. The roller platen assembly has a reciprocally driven carriage means containing at least one removably mounted cartridge containing at least one row of roller platens mounted therein in parallel, spaced apart relationship to each other. A plurality of backup rollers are rotatably mounted within said roller platen assembly, each in contact and vertical alignment with each of the platen rollers when the cartridge means is in position within the carriage means. At least one of the roller platens is in contact with the raised printing elements of the printing plate at all times during each printing cycle of the imprinter to thereby lessen any tendency for smudging of the form to occur.

Imprinter having a removable cartridge containing a plurality of roller

Imprinters for making printed impressions from tokens such as credit cards are provided in which the carriage which traverses the bed of the imprinter includes two independent roller platen mechanisms. Translation means responsive to travel of the platen along the bed at certain points causes the platen rollers to be raised to nonprinting position or lowered to printing position. The mechanism also includes a transition device which makes it possible to convert the imprinter from a condition in which the platen rollers are raised and lowered in concert to one in which the raised condition of one roller occurs when the other is lowered and vice versa. In the illustrated form the translation devices include interacting cam members, one set for each platen roller, and the transition device is shown as being one of the cam members which can occupy alternate positions in the assembly. There is also disclosed mechanism comprising an actuating cage moving transversely of the carriage path in response to encountering actuating cams along said path to effect motion of the translation cam members.

Imprinter with plural selectively operating platen rollers

A data recorder is provided including a removable cartridge which carries both a sales form and an underlying log sheet. The fixed and variable data are imprinted by reciprocation of a platen carriage, with return of the carriage to the home position causing ejection of the credit card and loading of a stored energy mechanism. When the sales form is removed, the stored energy mechanism is released, whereby the log sheet is incrementally advanced to the next position.
