ABSTRACT:
A hand operated label printing machine in which a series of labels are serially fed onto a printing platen in response to the squeezing of a hand lever so that they may be imprinted with selected indicia. The hand labeler is equipped with a constant pressure printing mechanism interposed between the hand lever and the frame of the hand labeler. That mechanism comprises a biased cam pivotally mounted to the hand lever and a roller on a biased support which support is pivotally mounted to the machine frame. The cam and roller are brought into abutment contact while the hand lever is being squeezed, and springs bias them into abutment and prevent their bypassage. The label printing force is the force that has to be applied for the cam to ride over the roller, which occurs when one of the springs resiliently deforms.
