Abstract

PURPOSE:To hold roll paper of several kinds with a single roll paper holder, by sliding a flange of a roll paper holding device to a shaft and engaging the flange in a click stopping state to plural annular grooves correspondig to a width of the paper. CONSTITUTION:A roll paper holder 11 of a roll paper holding device comprises a shaft 12, flange 14 and click mechansm 16. When roll paper 1 in width of, for instance, A4 size is mounted to this device, the flange 14 is slided to the shaft 12 to engage a ball 17 to an annular groove 13a for use of A4 size. Here the ball 17 is driven out from an annular groove 13b for use of, for instance, B4 size against tension of a spring 19, and then rolled on a major contour part 12a of th shaft 12 and engaged to the groove 13a for use of the A4 size by the tension of the spring 19. In this way, the flange 14 is slided to the shaft 12 to engage the ball 17 to the grooves 13a-13c alternatively further in a click stopping state, and the single holder 11 can be used for any one of the sizes A4, B4 and A3.

[Related to the 1-9M Hochi set-up picture used in . Such a #I container may contain paper from [1 to 1], e.g. thermal paper, fiIIA or ink tonneau sheet to
Rucho! It is often used to roll a large number of sheets of paper around. The U-rule paper is taken up in the equipment (d3 and 1n-ru paper holding device) to ensure smooth feeding of the paper. Examples of conventional O-ru paper holding devices include - There is a device configured as shown in Figs. 1 and 2.The O-roll paper 1 of this device is capable of handling a long paper 2 made of, for example, thermal paper, crane paper, ink dove sheet, etc. It is wound around a core 3.Both ends of the roll Wi1 are held by some D-leaf paper holders (one is not shown) 4.O-leaf paper holders 4 t, t, Large diameter portion 5a of shaft 5 with two-stage structure
A flange 6 is provided in the middle. The end of the large diameter 885a of the shaft 5 is removably fitted to the end of the core 3 of the roll paper 1, and the small diameter part 5b is fitted into the U-shaped recess 8Il18 of the support member 7 (one not shown). support +) c're

There is. The supplied A8 material 7 is fixed to a frame of a device (not shown). When mounting the roll M1 on this roll paper holding device, first, the both ends of the core 3 (a pair of [1 roll paper holders 4
A part of the large diameter portion 5a of each shaft 5 is fitted, and each of the seven flanges 6 is fitted onto the inner end surface 1. of the core 3. : Bring it into contact. After that, the small diameter portions 5b of each set 5 of the pair of 0-1 paper folders 4 are fed into the recesses 8 of the lower portions of each holder. As a result, O-le W
i1 is sandwiched between both seven flange 611 and its axial movement is obstructed, and is placed in a predetermined position corresponding to the recording section of the device.
Wa is attached. By the way, with one IIB, for example, A4 size, B4 Zino,
There are several kinds of ring w4 such as A3 ma Jl [l-ru @
1 may be used. In such a case, since the conventional HP has an integrated roll paper holder 4, it is necessary to prepare and install several types of large diameter portions 5a that exist between the flanone 6 and the small diameter portion 5b with different qualities. 1-I use one that corresponds to the width of paper 1. Therefore, when using a certain roll paper holder 4, other items must be stored, which requires space and there is a risk of loss. The present invention has been made in view of the above circumstances, and provides an 11-roll paper holding vt holder that can selectively hold several types of []-roll paper in one roll paper holder. In the present invention, the nononge that comes into contact with the end surface of the roll paper is brought into sliding alignment with the shaft in the direction of its axis lIb, and at a plurality of locations corresponding to the width of the roll paper. To achieve the purpose of selectively and click-clicking engagement, the present invention will be described in detail with reference to embodiments. Fig. 3 shows a milli-level view of the bottom of the O-ru paper holding S device, and Fig. 4 shows a vertical cross-sectional view of the inside of Fig. 13.In Fig. 143, The same parts as in Fig. 1 are given the same reference numerals to simplify the explanation.
