Band type label printer, for rolling up and unrolling of a band of labels, has photoelectric cells linked to control circuits for control of motors so that the tension of the label band is optimized to ensure high print quality

摘要

Device comprises a first support (6, 10) for a coiled band of labels and a second support (7, 14) for collecting the labels after they have been printed. Motors (8, 13) for movement of the label band are attached to the supports, while photoelectric cells are used with motor control circuits so that the band remains loose between the supports and the printer.
