Abstract
The disclosure concerns a constant pressure printing mechanism for use with a hand labeler. A continuous strip of labels is fed in increments by manual squeezing of a hand lever. The constant pressure printing mechanism includes a retaining member hinged to the frame of the hand labeler and biased by a spring into abutment contact with an actuating member, which is hinged to the hand lever. The actuating member is also biased by a tension spring to shift out of engagement with the retaining member until the actuating member is halted by a stopper. A release member is mounted on the hand lever for releasing the retaining member from engagement with the actuating member when the hand lever is squeezed toward the grip. Thus, printing is effected under a constant pressure that is determined by the inertia of the hand lever caused by the release of said actuating member irrespective of the intensity of the squeezing force of the hand lever.
