Abstract: The machine comprises a print table (8) and a print head (3) which are intended for the printing of characters on labels (11) borne by a continuous strip (10).The print head (3) comprises a pusher (32), a lateral stop (29) and two detention notches (30, 31), and the print table (8) has a rotary cam (33) with return prism (34) and cocking spring (35), having three lifts (38).Upon the typing, one lift is turned by the pusher (32) and the following lift comes laterally against the stop (29). When the print head rebounds, this lift engages in a notch (30) and holds the print head spaced from the print table.This arrangement is provided to prevent a second printing of characters on the labels as a result of rebound. In a variant, the rotary cam is replaced by a reciprocating bolt.

Abstract: A constant pressure printing mechanism for use in a label printing machine: the platen is pivotally secured to the machine body; the pivotally supported, hand operated printing levers include a projection, which engages a pivotally supported platen lifting member, and the lifting member is pivoted by the projection to turn the platen toward the printing head, whereby the printing head and the platen are moved near to each other to perform the printing of labels.

Abstract: A printing pressure damping mechanism for a hand labeler: A printing platen is pivotally mounted on the frame of the hand labeler. The platen has a printing portion at one side of its center of pivotal motion. A hand lever pivotally connected to the frame of the labeler carries a printing head, which is turned toward the printing platen when the hand lever is squeezed against the biasing force of a return spring. Shock-absorbing means, comprising a leaf spring on the hand lever and an elastic abutment member on the other side of the printing platen from the printing portion engage to turn the printing portion of the printing platen toward the printing head. The hand lever is further squeezed and moves to overcome the biasing force of the leaf spring when the printing head abuts against the printing portion of the platen. The squeezing force, which might otherwise be applied as a printing force to the printing platen through the hand lever, is damped to a preset level.
