<p>An imprinter (1, 60) for imprinting characters from a credit card (2) onto a docket (3) comprises a base (4) of plastics material, and a carrier (16, 70) slidably movable across the base (4) having imprinter rollers (17a, 17b) to imprint characters onto the docket (3). The base (4) has a receiving area (8), to receive a credit card and a flat upwardly facing panel (10), to receive a docket (3). The carrier (16, 70) transversely spans the base (4) and is longitudinally slidably movable over the document supporting panel (10) from a start position at one end of the panel (10) to a reversing return position at the other end of the panel (10) and back to the start position. Cam blocks (48, 49, 68) integrally moulded with the base (4) cooperate with cam followers (42, 61, 62) mounted in the carrier (16, 70) to move the imprinter rollers (17a, 17b) from a raised inactive position to a lowered imprinting position engaging a docket (3) to imprint characters from the credit card (2), merchants plate (14) and dating mechanism onto the docket (3) during movement of the carrier member (16, 70) between the start and return positions. Track means (20) are provided on the base (4), and the carrier (16, 70) includes four pairs of spaced apart roller bearings (26, 27) which engage opposing faces (21, 22) of the track means (20) with a pinch action enabling smooth movement of the carrier (16, 70) over the base (4).</p> |
