ABSTRACT:
A printing machine in which a series of selectively settable type wheels arranged in the housing of the machine extend with portions thereof through openings in a printing bed fixedly mounted on the machine housing. A credit card supporting plate is mounted on the printing bed adjustable relative thereto and a curved leaf spring, substantially of the same outline as the credit card supporting plate, is placed between the latter and the printing bed to bias the credit card supporting plate in a direction away from the upper surface of the printing bed. A carriage, rotatably carrying a platen roller, is mounted on the printing bed movable across the latter so that a credit card supported on the credit card supporting plate and types on the type wheels may be printed on a sheet placed over the credit card and the type wheels. Due to the adjustable mounting of the credit card supporting plate on the printing bed a proper printing of the types will be assured regardless of the thickness of the credit card placed on the credit card supporting plate.
