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.

Abstract: The disclosure concerns a printing device for use with a hand labeler, or the like. The printing device includes a platen and a printing head which carries a plurality of types on its printing surface, and which is moved into and out of contact with the platen thereby to print a label with a row of type characters. A type receiving plate is a part of the platen and it is made of an elastic material. The type receiving plate has dividing grooves which are parallel to one another and define type receiving lands. The type receiving lands are positioned to register with respective type characters when the printing head operates. The lands can be elastically deformed independently of one another. Thus, the type receiving lands can cooperate with the respective types to provide uniform printing pressure during the printing operation.
