載）。2. Description of the Related Art Conventionally, a label roll holding structure for a label roll holding shaft in a label printer of this type has a structure in which one end is released and the other end is bolted to the inner wall of the printer body. A label roll holding shaft (mounting boss) that is mounted in a shape, and a roll holding plate (guide panel) that detachably attaches one open end to the roll holding shaft, and is made of spring steel attached to the roll holding plate. The pair of hooking claws (chuck) are pushed into the hooking step (hook) provided on the label roll holding shaft, so that the label roll rotatably fitted and inserted into the label roll holding shaft is engaged. The holding shaft was held by a roll holding plate (described in Japanese Utility Model Application Laid-Open No. 61-118038).

嵌挿着することができる。Next, how to attach the roll holding plate 7 to the label roll holding shaft 6 and how to remove the same will be described.
The roll holding plate 7 is pushed in such a manner as to be opposed to the hooking claws 12 and the rotation preventing projections 16 of the shaft fitting opening 15 and the concave and convex hooking portions 8 and the concave grooves 14 on the outer periphery of the label roll holding shaft 6, respectively. Then, the hook claw
Numeral 12 moves freely over the claw guide inclined portion 8-1 of the concave and convex latching portion 8 by the support of the elastic supporting portion 13, and the rotation preventing projection 16 is fitted into the concave groove 14 by latching.
It serves to guide the above 12 movements. That is, the roll holding plate 7 is prevented from rotating so as not to rotate during the pushing operation. By stopping the pressing operation of the roll holding plate 7 at a position where the pressing member 7 comes into contact with the label roll 3, the locking claw is received and caught by the claw locking portion 8-2 of the convex / concave locking portion 8 in any of the axial directions, and the roll pressing plate is stopped. 7 is fitted and inserted on the outer periphery of the label roll holding shaft 6 (the state shown in FIG. 2). Therefore, the roll holding plate 7 can be similarly fitted to the label rolls having different widths.

At 2, the roll holding plate 7 is turned in the circumferential direction (right direction in the figure) so as to remove the hooking claws 12 from the concave / convex engaging portions 8 and the detent protrusions 16 from the concave grooves 14. After releasing the locking state of the locking claw 12 with respect to the label 8, the operation of pulling the roll pressing plate 7 forward can be easily removed from the label roll holding shaft 6. At this time, the elastic support 13
5 moves along the outer periphery of the label roll holding shaft 6 (the state shown in FIGS. 5 and 6).

ることはない。[Effects of the Invention] The label roll holding structure of the label printer of the present invention is constructed as described above. . The roll holding plate can be fitted and inserted by pushing the locking claw of the roll holding plate into one of the concave and convex hooking portions continuously provided in the axial direction of the outer periphery of the label roll holding shaft and hooking the roll holding plate. . When the roll holding plate is fitted and inserted into the label roll holding shaft, the roll holding plate is pushed into the label roll holding shaft with the hooking claw positioned on the uneven hooking portion on the outer periphery of the roll holding shaft. , The hook claw elastically supported by the shaft fitting insertion opening of the roll holding plate can freely pass over the claw guide inclined portion of the uneven hooking portion, and the vertical hook of the uneven hooking portion in any of the axial directions. The roll holding plate can be securely fitted and inserted on the outer periphery of the roll holding shaft without being stopped by the receiving portion and coming off from the label roll holding shaft. . The roll holding plate is fitted and inserted into the label roll holding shaft, and at the same time, the detent protrusion provided in the shaft fitting insertion hole is hooked into a concave groove extending in the axial direction on the outer periphery of the label roll holding shaft, thereby holding the label. It does not rotate with the rotation of the fed label roll.
