  In the tack labeler 1 configured as described above, when the tack label TL is peeled from the release paper SP by the label peeling unit 12 of the label supply device 3, the label supply strips LB spanned in an S-shape are 2 When passing the individual free rollers 15a and 15b, the adhesive layer of the tack label TL adhered to the release paper SP is loosened, and the presser member 14 presses the label supply strip LB downstream thereof. As a result, the label supply strip LB is not separated from the tip of the peeling plate 13, so even if the tack label TL attached to the release paper SP is thin and thin, In such a state that such a tack label TL is adhered to the release paper SP, the direction of the release plate 13 is not changed with the release paper SP, and the thin tack label with no waist is provided. It is possible to reliably separated the TL from the release paper SP.

  7 to 9 show other embodiments of the label peeling unit. This label peeling unit also has basically the same configuration as the label peeling unit 12 described above, and only the configuration around the peeling plate 13 is different. Therefore, the same components are denoted by the same reference numerals. The description thereof will be omitted, and different components will be described in detail.

  This label peeling unit does not include an independent pressing member for pressing the label supply band LB, and the label supply unit out of the two free rollers 15a and 15b that hangs the label supply band LB in an S shape.
