Abstract
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.
