Disclosed is a hand-held labeler or apparatus for printing and applying pressure sensitive labels. The apparatus has a housing, a rigid, metal, frame plate mounted by the housing, a platen and a cooperating print head, a delaminator for delaminating printed labels from the web of supporting material on which the labels are carried, an applicator for applying the printed labels, a feed wheel having teeth for engaging and advancing the web, a manually operable actuator drivingly connected to the feed wheel and the print head, a brake, and an ink roll for inking the print head. The apparatus also includes a feed wheel assembly having a feed wheel driven by a pawl and ratchet mechanism. The pawl and ratchet mechanism is adjustably connected to the feed wheel. There is also disclosed an arrangement by which the print head can be tripped or fires after the actuator is moved through a predetermined distance. The apparatus has gears which are coupled through a lost-motion connection. When the actuator and one of the gears have moved through a predetermined distance a spring is released to cause the other gear to move the print head into printing cooperation with the platen. |
