Abstract

A precision tape feed and guide mechanism is disclosed. The guide includes a base plate (308) and a hold-down plate (314) with fingers (316, 318). A spring (345) biases the fingers against the tape (301) during printing. Actuation lever (330) which is pivoted on point (332) causes plate (314) to lift out of contact with the tape and permit its easy removal. Feeding or incrementation of the tape is accomplished by an incompressible roller (350) removably biased against roller (352) which includes a recessed portion (356) having an incompressible O-ring (354) residing therein and biased against roller (350) with a tape (301) therebetween.
