ABSTRACT:
An imprinter apparatus selectively raises and lowers a print roll (100 or 102) over a print bed (12) for receiving a station plate and conventional credit card to produce a receipt for a credit transaction. The print rolls are freely suspended from a cross member (60) of the carriage (14) for independent pendulous movement that is restricted in one direction to provide pressure for printing and less restricted in the return direction to avoid ghosting. The trolley for the carriage includes a nylon slipper (130) which has on one surface axles for wheels (50-52) that run on the lower side of the print bed (12) and a slider (144) on the upper print bed side; on the other side of slipper (130), pins (140, 142) are provided that protrude through the steel carriage wall (62 or 64) for preventing relative movement between the trolley and the carriage (12). The various parts are designed to fit together with a minimum of secondary operations to reduce manufacturing costs.
