An engagement step 12f that engages with the elastic engaging piece 22a of the shaft core 11 is formed near the inner diameter end edge of the end closing part 12c, and is formed between the elastic engaging piece 22a and the engaging step 12f. The engagement restricts outward movement of the cover 12.
[0035]
Further, the inner diameter of the bearing portion 12a is set to be slightly larger than the outer diameter of the operating member 22 in the shaft core 11, thereby slightly shaking or tilting the axis of the cored roll paper R or the coreless roll paper RR. And a function of facilitating the feeding of the cored roll paper R or the coreless roll paper RR and a function of facilitating the connection between the shaft core 11 and the cover 12. Note that the same material, for example, a hard plastic material, can be used as the material of the shaft core 11 and the cover 12. In this case, since the friction coefficient is the same, the rotation of the operation member 22 that slides on the bearing portion 12a increases the stability.
[0036]
The anti-rolling pedestal 12d horizontally connects a mounting inclined surface 12g extending obliquely downward from below the feeding opening 12e formed in the covering portion 12b, and a lower end of the mounting inclined surface 12g and a lowermost portion of the covering portion 12b. And a pedestal surface 12h having a substantial rolling prevention action. The mounting inclined surface 12g is formed in the engaging groove 13 formed behind the paper feed port 140 of the ink jet recording apparatus 100 as shown in FIG. 7 or the post-attachment 15 as shown in FIG. An engaging claw 12i that is engaged with and held by the engaging groove 15a is formed. Here, the post-attachment 15 is configured to be attached using, for example, an attached portion for attaching a paper support, whereby an ink-jet recording apparatus having no engagement groove 13 can be used in a roll paper holder. 10 can be applied.
[0037]
Between the engagement grooves 13 and 15a and the engagement claws 12i, there is provided a left and right wrong mounting prevention mechanism for regulating a mounting position of the cover 12. That is, the positions of the positioning slits 13b and 15c formed in the holding action portions 13a and 15b that perform the substantial holding action in the engagement grooves 13 and 15a, and the positioning ribs vertically rising from the holding hooks 12j of the engaging claws 12i. By setting the position of 12k not to be symmetrical but set to a position slightly deviated to the left or right, it is impossible to mount even if the mounting is mistakenly performed with the left and right reversed.
