ABSTRACT:
A bidirectional imprinter having a print roll carriage with sidewalls and two pairs of inclined slots disposed in the sidewalls where the first pair is oppositely inclined with respect to the second pair. First and second print rolls are respectively associated with the first and second pairs of slots so that movement of the carriage over the print bed causes the first print roll to move down its associated slot pair to effect imprinting while the second print roll is moved up its associated slot pair in a non-imprinting relation with respect to the print bed. The functions of the print rolls are interchanged during the reverse stroke. The imprinter may comprise a unitary, extruded base with an elongated receptacle extending along the upper length thereof and a molded plastic print bed inserted within the receptacle. An elongated recess in the print bed may also be provided so that a portion of a credit card or the like overlying the recess can be depressed therein to raise the remainder of the card and permit easy removal thereof.
