Description

[Detailed Description of the Invention] This invention relates to a label printer, and more particularly to a device for winding up a mount after printing on a label pasted on a mount.

In recent years, the cases used in stores are taller and smaller in depth. Therefore, it is desirable that the label printer used on such a show case has a small depth.
Furthermore, as sales cases have become taller, it is desirable for label printers to be short so that customers and sales staff can have face-to-face conversations. However, in a conventional label printer, as shown in FIG. There is one in which the printed label 5 is peeled off, and the peeled backing paper 3 is wound up on a winding shaft 7 provided at a high position away from the support shaft 6 of the label supply section 1 and parallel to the support shaft 6. In this label printer, since the take-up shaft 7 is provided in parallel at a high position away from the support shaft 6, both the height dimension H and the depth dimension W of the outer shell 8 of the label printer become large, and the above-mentioned case It was inappropriate to put it on top.

The object of this invention is to provide a label printer that is small in both height and depth.

This invention will be explained in detail below based on one embodiment shown in FIGS. 2 to 5. In FIG. 2, 10 is the outer shell of the label printer, and inside it is a support shaft 12 fixedly supported as shown in FIG.
A mount 16 on which a non-printed label 14 is temporarily pasted along its length is wound around a core (not shown), and this is inserted through a support shaft 12, allowing it to rotate freely. , the label supply section 18
It consists of

The label 14 pulled out together with the mount 16 from the label supply section 18 is printed by a printer 20 provided on the side of the label supply section 18.
The mount 16 that comes out from 0 is connected to the shaft bodies 24, 26, 28,
Although it is arranged coaxially with the support shaft 12 via a conveyance path formed by 30, 32, and 34, it is inserted into the support shaft 12 and wound up on a rotatable winding shaft 36. Although not shown in the figure, the winding shaft 3
6 is connected to a driving device for driving this.

The shaft 24 is disposed near the printer 20 and parallel to the winding shaft 36, and the shaft 26 is wound at approximately the same height as the shaft 24 between the tape supply section 18 and the shaft 24. It is provided parallel to the shaft 36. The shaft body 28 is located between the winding shaft 36 and the shaft body 26 at a position biased toward the winding shaft 36 .
It is provided parallel to the winding shaft 36 at a higher position than the winding shaft 36. The shaft 30 is disposed at a higher position than the shaft 28 and on the opposite side of the shaft 28 with the winding shaft 36 as a reference so as to form an angle α with the winding shaft 36. The shaft 32 is provided parallel to the shaft 30 between the shaft 30 and the shaft 28 and at a higher position than the shaft 30 . Note that the shaft body 32 is longer in length than the shaft body 30. The shaft 34 is provided on the side of the shaft 30 at the same height as the shaft 32 and parallel to the winding shaft 36 . These shafts 2
A mount 16 is stretched between 4 and 34 as shown in FIG. , is folded back toward the shaft body 34 side at the shaft body 32 portion. In particular, the mount 16 is attached to the tip end side of the shaft body 32.
By stretching the tape, it is folded back so as to protrude toward the winding shaft 36 by approximately the same dimension as the width of the mount 16. The shaft body 24 is a folding member, and the shaft body 30 is a first
The shaft body 32 corresponds to the second transfer route changing member.

In the label printer configured in this manner, when the take-up shaft 36 is rotated in the direction shown by the arrow 38 in FIG. rotate,
The mount 16 is pulled out from the label supply section 18 together with the blank label 14, and the blank label 14 is fed into the printer 20, where it is printed. When the take-up shaft 36 is further rotated in the direction of the arrow 38 after the printing device is finished, the mount 16 is folded back at the position of the shaft 24, the label 22 that has been printed is peeled off, and the mount 16 is moved between the shafts 26 and 34. are moved in order, and the transfer path changes to the outside of the winding shaft 36, particularly at the positions of the shaft bodies 30 and 32, and the winding material is wound on the winding shaft 36.

In the label printer according to this invention, the backing paper is wound up on the winding shaft that passes through the supply section and projects laterally, so that the height and depth of the outer shell of the label printer can be reduced. Moreover, since the rotational direction of the supply section and the rotational direction of the take-up shaft are opposite to each other, even if the drive device is stopped, the mount does not rotate due to inertia and sag does not occur. For example, a device that winds up a long body around a winding shaft located on the same axis as the supply section while rotating it in the opposite direction to the rotation direction of the supply section is
It is disclosed in Publication No. 28049. However, since the long body is a typewriter ribbon cartridge, by folding the ribbon cartridge with a triangular peeling member, the ribbon cartridge can be rotated in the opposite direction to the rotation direction of the supply unit. It's being rolled up. When this technique is applied to a label printer, the peeling member 100 is formed into a triangular shape as shown in FIG. It must be rolled up. In the same figure, 1
04, 104... are labels. However, in this case, when peeling off the printed label, as shown with diagonal lines in the same figure, the backing paper 102 and the label 1
04 is only temporarily attached to one corner of the label 104, making it difficult to peel off. It is also possible to stop the backing paper with the label exposed to the apex side of the triangle and peel it off, but in that case, the backing paper 102,
The temporarily bonded portion with the label 104 becomes even smaller and becomes unstable. Therefore, as long as the printer is a label printer, it is necessary to peel off the label using a linear peeling member provided parallel to the width direction of the mount as in this invention. In order to perform peeling in this manner, the rotational direction of the supply section and the rotational direction of the winding shaft are reversed using the first and second transfer path changing members. Therefore, according to this invention, the label can be easily peeled off, and even if the drive of the winding shaft is stopped, the mount does not sag.

In the above embodiment, the support shaft 12 and the take-up shaft 36 are arranged on the same axis, but they may be arranged slightly offset. Although the shaft bodies 24 to 34 are used, rollers may be used instead. Also, the shaft bodies 26, 2
8 and 30 are omitted, and the mount 1 is directly attached to the shaft body 24.
6 may be stretched over the tip of the shaft body 32.
