HAND OPERATED LABEL PRINTING MACHINE ABSTRACT OF THE DISCLOSURE A hand operated label printing machine in which a series of labels are incrementally 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 is comprised of a pressure applying assembly in the form of a biased cam pivotally mounted to the hand lever and a pressure receiving assembly also in the form of a biased cam pivotally mounted to the machine frame. The former assembly is brought into abutment contact with the latter assembly at their cam surfaces, while the hand lever is being squeezed and the cams are then hindered from pivoting following abutment. The label printing force is the force that has to be applied for the former assembly to ride over the latter assembly which occurs when one of the assemblies resiliently deforms. The hand labeler also has an ink supply device, comprising a holder that holds two inking rollers. The ink supply device is movable to bring the inking rollers into and out of contact with the types of the printing device to ink them. The ink supply device is actuated by a mechanism which is comprised of a combination of a cam pivotally attached to the machine frame and a roller pivotable with the printing head supporting printing lever for being received in the cam and for pivoting the cam with the printing lever. A link joins the cam with the holder, so that pivoting of the cam moves the holder. Guide grooves in the machine frame regulate the inking roller motion along different loci. The link has a slot in it which prevents the holder from linear protrusion to the front of the labeler frame.
