Retention device of barcode printer

Abstract

A roller retention device is provided for a barcode printer and includes a base and at least one peeling board, wherein the base is mounted to an enclosure of the barcode printer. The base has a front portion forming at least one first channel for accommodating a rear portion of a label sheet hold-down roller of the barcode printer. The first channel has a peripheral portion forming at least one connection segment. The peeling board has a rear portion forming a second channel which matches with the first channel in order to accommodate a front portion of the label sheet hold-down roller. The second channel has a peripheral portion forming a coupling segment which corresponds to and is fixed to the connection segment of the base, allowing the label sheet hold-down roller of the barcode printer to be retained and accommodated between the first channel of the base and the second channel of the peeling board. The peeling board features the function of peeling the barcode label stickers off a release paper. Thus, a retention device that features both retention of the roller of a barcode printer and peeling of the barcode label stickers is provided.

1 . A roller retention device for a barcode printer, comprising:
 a base having a peripheral portion adapted to couple to an inside wall of en enclosure of the barcode printer, the base having a front portion forming at least one first channel for accommodating a rear portion of a label sheet hold-down roller of the barcode printer, the first channel having a front face forming at least one connection segment; and   at least one peeling board for peeling barcode label stickers of the barcode printer, the peeling board having a rear portion forming a second channel matching the first channel for accommodating a front portion of the label sheet hold-down roller, the second channel having a peripheral portion forming at least one coupling segment, the coupling segment corresponding to and fixed to the connection segment of the base, allowing the label sheet hold-down roller to be retained and accommodated between the first channel of the base and the second channel of the peeling board.
