BACKGROUND OF THE INVENTION
The present invention relates to a paper winder.
[0002]
[Prior art]
Conventionally, in a one-hand cut type paper winder that can pull out and cut paper with one hand, the paper cutting plate is pressurized on the upper surface of the roll paper to be mounted, and the pressure is set constant. There are some (for example, refer to Patent Document 1).

[Patent Document 1]
Japanese Utility Model Publication No. 6-77687
[Problems to be solved by the invention]
There are various types of roll paper, such as paper that is easy to tear and paper that is difficult to tear. Depending on the paper, the applied pressure is too strong to pull out from the paper winder. There is a problem that the paper suitable for use is limited because the pressure is too weak and the paper cannot be cut with one hand.
[0005]
[Means for Solving the Problems]
The present invention has been devised in view of the above-described conventional problems, and even if it is a roll paper having a paper quality that is easy to tear or a roll paper having a paper quality that is difficult to tear, it can be pulled out and cut well with one hand. SUMMARY OF THE INVENTION The first aspect of the present invention is to provide a paper cutting plate that comes into contact with the upper surface of the loaded roll paper, and to apply the paper cutting plate to the roll paper. A weight capable of generating pressure is stored in a storage recess of the weight case, and a locking protrusion that protrudes laterally is formed on the side surface of the weight case, which is formed on the back surface of the paper cutting plate. A latching protrusion of the weight case is slid and attached to the hooking piece, and a weight is detachably disposed between the back surface of the paper cutting plate and the roll paper, and the paper cutting The roll of the plate Is that configured to calibrate their pressure to par.
Further, the second aspect, the weight is that configured to be able to change the weight and change or add.
The third gist is that a plurality of hook pieces are provided on the back surface of the paper cutting plate so that the attachment position of the weight can be changed.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of a reference example of a paper winder. The paper winder 1 is a paper cutting plate that can be opened and closed in the vertical direction on the upper surface side of a main body 2 having support claws 3 and 3 capable of supporting roll paper. 4 is provided, and this paper cutting plate 4 can be rotated in the vertical direction via a shaft 5, and a blade 6 is provided on the tip side.
In this example, the weight 20 is configured to be detachably attached to the back surface of the paper cutting plate 4 with a magnet or an adhesive tape, and the weight 20 is close to the blade 6 on the back surface of the paper cutting plate 4. When attached at the position P1, when this paper cutting plate 4 comes into contact with the upper surface of the roll paper mounted on the main body 2, it comes into contact with the upper surface of the roll paper with a strong pressure. Even when the paper is thick and hard to tear, a good pressure can be obtained and the paper can be cut with one hand.
[0007]
Further, when the weight 20 is attached to the position of P2 in the center of the back surface of the paper cutting plate 4, even when the paper quality of the roll paper is slightly thin and difficult to pull out, it can be cut with one hand with good pressure. It will be a thing.
Furthermore, when the weight 20 is attached at a position P3 close to the shaft 5, even when the roll paper is very thin and easy to tear, it can be pulled out and used satisfactorily.
As described above, the position where the weight 20 is attached to the back side of the paper cutting plate 4 can be changed, and the pressure can be adjusted well, so that it is possible to cope with roll paper of any paper quality.
[0008]
If several types of weights 20 having different weights are prepared, they can be exchanged for ones having different weights, and the applied pressure can be adjusted more favorably.
Furthermore, the weight 20 may be formed of a thin plate, and the number of weights 20 may be added to increase the weight and adjust the applied pressure.
[0009]
FIG. 2 shows an exploded perspective view of a paper cutting board according to an embodiment of the present invention, in which a weight is attached by a hook type, and the weight 20 is composed of a weight case 21 in which a weight storage recess 21a is formed in a recessed shape. On the left and right side surfaces of the weight case 21, a pair of locking projections 21b and 21b are formed to protrude sideways, and a stopper piece 21c is formed on one side of the locking projection piece 21b. It is provided in a letter shape.
On the other hand, a plurality of hooks can be attached to the weight case 21 so as to be detachably hooked on the inner sides of the side edge hanging pieces 7, 7 integrally formed in a hanging shape on both left and right edges on the back side of the paper cutting plate 4 The pieces 8a, 8b, 8c, 8d are formed at intervals from the blade 6 side to the shaft 5 side. A cross-sectional configuration diagram of the paper cutting plate 4 is shown in FIG.
[0010]
In such a configuration, in a state where a plurality of plate-like weights are stored in the weight storage recess 21a of the weight case 21, the weight storage recess 21a is inverted as shown in FIG. A weight case 21 can be attached to the paper cutting board 4.
At this time, the locking protrusions 21b and 21b of the weight case 21 are slid and hooked on the hooking pieces 8a and 8b of the paper cutting plate 4, and the stopper piece 21c is brought into contact with the hooking piece 8b and positioned. The weight case 21 can be attached to the position P1 on the blade 6 side on the back side of the paper cutting board 4 and is hooked on the hooking pieces 8b and 8c so that the weight case 21 is placed at the position P2 in the center of the paper cutting board 4. The mounting position can be changed, and further, by hooking between the hooking pieces 8c and 8d, the mounting position can be changed to the position of P3 on the shaft 5 side. By changing the mounting position, The applied pressure can be adjusted appropriately.
[0011]
In the weight housing recess 21a of the weight case 21, for example, two, three, or four plate-like stainless steel plates are accommodated, and the weight is changed by adding the number of stainless steel plates. The pressure can be adjusted.
[0012]
【The invention's effect】
The paper roll of the present invention includes a paper cutting plate that comes into contact with the upper surface of the loaded roll paper, and a weight capable of generating a pressure applied to the roll paper by the paper cutting plate is contained in a storage recess of the weight case. The weight case is formed with a locking protrusion protruding laterally on the side surface of the weight case, and the locking protrusion of the weight case is attached to the hook formed on the back surface of the paper cutting plate. Sliding and hooking and mounting, a weight is detachably disposed between the back side of the paper cutting plate and the roll paper, and the pressure applied to the roll paper by the paper cutting plate can be adjusted. Thus, it becomes possible to draw out any paper-type roll paper satisfactorily and cut it with one hand for use.
Furthermore, because the weight is configured to be placed in the weight case, it is easy to change the weight as necessary, and when attaching the weight case to the paper cutting board, it can be easily attached by sliding. It will be a thing. Moreover, since the weight is disposed between the back surface of the paper cutting plate and the roll paper, the weight is not visible during use, and the appearance is good.
[0013]
Furthermore, it said weight is by constructing to be able to change the weight and replace or add, or replace the different weights of weights, or by changing the weight by adding the number of weights, The pressure applied to the paper cutting plate can be adjusted satisfactorily.
[0014]
In addition, by providing a plurality of hooking pieces on the back surface of the paper cutting plate so that the mounting position of the weight can be changed, the mounting position of the weight is appropriately changed, and the pressure of the paper cutting plate is improved. It can be adjusted.
