ABSTRACT:
A label strip jam preventing mechanism for use in a hand labeler wherein the labeler is equipped with a feed mechanism having a feeding roller that is rotatably mounted on the frame of the hand labeler for feeding a continuous label strip. A label strip charging mechanism having a pressure plate covering the feeding roller for assuring engagement between the feeding roller and the label strip. A platen which is reciprocally movable toward and away from a printing head for printing the label strip. The label jam preventing mechanism includes a passage plate which is pivotally connected to the frame and to the platen for providing a passage between the pressure plate and the platen, as the platen shifts in position. A first label holding assembly holds both edges of the label strip at the passage plate. A second label holding assembly holds the both edges and the center portion of the label strip at the pressure plate. Thus, the label strip can be prevented from becoming slack and jamming in the passage between the label supply roll and the platen.
