Abstract
A portable label printing and applying machine: a platen to support the label to be printed is attached to the machine frame; a printing head is placed above the platen; a spring pushes the printing head down toward the platen with a constant pressure and for a constant time period, regardless of the strength and the duration of the squeezing of the operating hand lever of the machine; the printing head is restrained from descending until the spring has been adequately charged by squeezing of the hand lever, and then the printing head is released to descend. The printing head is separated from the platen immediately after its descent to and contact against the platen. In addition, there is a second spring acting on the printing head in opposition to the first mentioned spring to raise the printing head off the platen. In one embodiment, the first spring is apart from the printing head but acts on it. In another embodiment, the printing head is comprised of a number of relatively movable parts; the first spring for moving the head to the platen is in the printing head and is charged by relative motion of the parts of the printing head.
