Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a paper roll machine in which a roll paper is rotatably supported via a support shaft between left and right walls having substantially cut out upper and lower walls.

Structure of the Conventional Example and its Problems Conventional paper rolls of this type have been assembled as shown in FIGS. 1 to 4. That is, first insert the insertion port 1 into the main body A, insert the side plate member 2 from two places behind, and then insert the engagement step 2' on the periphery of the side plate member 2 into the locking step of the flange-like strip portion 3a of the main body A. At the same time as engaging with the portion 4, the hooking piece 5 at the rear end
is brought into contact with the back surface of the back part 3b to form a hollow side part B.
Configure. At this time, the support shaft 6 is inserted into the recess 7 in an upright position so as not to interfere with the insertion of the side plate member 2 from the insertion opening 1 into the main body A. Since the side end portion of the cylindrical portion 7' of the recess 7 abuts against the side surface portion 3c, the open groove portion of the cut groove 8 is closed and the cut groove 8 is closed.
The inner pivot 9 cannot be pulled out not only in the left and right sides but also in the front and rear directions. Next, the elastic body 10 made of an elastic foam such as a sponge is placed inside the upper part of the recess 7, and the side surface 3c
using adhesive or the like, and attaching the locking pin 11 of the side plate member 2 to the side plate member 2.
The paper cutting plate 13 is attached to the main body A by hooking the curved piece 12 at the rear end to the side surface part 3c.
By engaging across the back plate member locking step portion 15 at the rear end and the locking step portion 4 of the bridge-like strip plate portion 3a', the back portion is closed to form a hollow back portion C. Ta.

When loading roll paper into the paper roll machine, when the roll paper is inserted from below between the left and right side plate members 2, the support shaft 6 is pushed up by the roll paper and rotated upward, causing elastic bubbles to form. The roll paper is pushed into the recess 7 while pressing the elastic body 10, and the center core of the roll paper is pushed into the support shaft 6.
When the external force applied to the support shaft 6 is removed, the pair of left and right support shafts 6 are restored to their original horizontal position due to the elastic force of the resilient body 10 to support the roll paper. Ta.

However, in the above conventional configuration, the side plate member 2 is separately provided to configure the hollow side portion B, or the projectile body 10 is separately provided and attached, which makes assembly time-consuming. In addition to requiring a large number of components, it is also expensive in terms of cost.
