ABSTRACT:
A variable field imprinter is provided including a platen carriage adapted to be reciprocated over an imprinting surface and then locked in a position to one side of the imprinting surface by a releasable blocking system. The blocking system consists of (i) a platen carriage blocking mechanism and (ii) a digit wheel sensing mechanism these two mechanisms must be interconnected by a credit card. Resetting of at least one of the digit wheels provides a force from the digit wheel sensing mechanism which is transmitted by the credit card to the platen carriage blocking mechanism to disarm the blocking system so that the platen carriage can be moved for imprinting.
