ABSTRACT:
A label strip charging mechanism for use in a hand labeler which is equipped with a feed mechanism having a feeding roller for feeding a continuous label strip: The label strip charging mechanism includes a pressure plate which is made pivotable with respect to the hand labeler and which is formed with a curved surface that follows the profile of the outer periphery of the feeding roller. A coil spring is connected to the pressure plate so as to normally bias the plate away from the feeding roller. A snap connection is used to retain the pressure plate in the vicinity of the feeding roller, against the bias of the coil spring at a position to form a restricted passage for the label strip. An actuating lever of the pressure plate is manually operated to release the snap connection so that the pressure plate can be moved away from the feeding roller by the action of the coil spring to establish an enlarged clearance thereby to facilitate charging of the label strip.
