SOLUTION: An edge section 2a of a cover 2 that is warped in an arc shape is pulled up by paper, rotation is stopped on the surface of a plate rear surface 2b by press force obtained by the lead-in force of the roll paper 5 and that obtained by the principles of a lever, and the roll paper 5 is cut finely by the edge section 5a of the cover 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper holder that can be used with one hand.

[0002]

2. Description of the Related Art A conventional paper holder is of a type in which one hand pulls out a paper and cuts the paper, and the other hand presses the paper holder cover to cut the paper using both hands.

[0003]

The above-mentioned conventional paper holder is of a type that can be cut cleanly by using both hands. If used with one hand, it is difficult to cut an appropriate amount of paper, and only one hand can be used for convenience. If it is not, it is difficult to use.In addition, since the cover and the paper are in close contact, you may have to touch the cover to pick out and remove the paper. There were hygiene problems by touching.

[0004]

SUMMARY OF THE INVENTION In order to solve the problems of the conventional paper holder, the present invention provides a main body 1 provided with a support portion 4 for supporting a roll paper 5, and a bearing provided at the tip of the main body 1. 3, a rotating shaft 6 of the arc-shaped cover 2 which is warped in the opposite direction to the surface of the roll paper 5 is pivotably supported so as to constitute a holder in which the cover 2 covers the roll paper 5.

[0005]

[Function] In this paper holder, roll paper 5
By pulling out the paper downward, the resistance can be pulled out with little resistance, and the cutting can be done by pulling up the required amount of paper, so that the blade portion 2a of the cover 2 is pulled up with the rotating shaft 6 as a fulcrum, and the back plate 2b of the rear portion pulls up the roll paper 5. Press
Cutting is performed while the rotation of the roll paper 5 is prevented.

At the time of cutting when the arc of the cover 2 is small, the paper adheres to the back 2b of the cover 2 to increase the contact area and increase the frictional resistance. With this frictional resistance, the arc-shaped cover 2 increases the pressing force generated in the direction of the roll paper 5 due to the drawing-in force (wind-in force) of the paper, thereby preventing the roll paper 5 from rotating.

[0007] The increased rotation stopping force of the paper makes it possible to shorten the length from the rotating shaft 6 of the cover 2 to the blade portion 2 a, thereby bringing the bearing 3 of the main body 1 closer to the supporting portion 4 of the roll paper 5, and Can be smaller.

Since there is a space between the roll paper 5 and the blade portion 2a of the cover 2, after the paper is cut, the leading end of the paper is not in contact with the cover 2 so that it can be easily picked up.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on embodiments shown in the accompanying drawings. 1 is a perspective view of a holder embodiment, FIG. 2 is an explanatory view from the side of FIG. 1, FIG. 3 is an explanatory view showing a contact area between a cover and paper, and FIG. FIG. 5 is an explanatory diagram showing the applied force, FIG. 5 is an explanatory diagram showing the cover after extending the entire length thereof, and FIG. 6 is an explanatory diagram showing a rotating space of the cover, and FIG. 8 is a plan view from the rotation axis of the cover to the rear part of the cover, FIG. 9 is a plan view of FIG. 8 with the plane bent and a similar type of arc-shaped cover, and FIG. FIG. 3 is an explanatory diagram showing the position of a cover.

FIGS. 1 and 2 show a case where a rear portion 1a of a main body 1 is fixed to a wall surface with screws, an adhesive, a tape, or the like, and a main body side plate 1b is provided.
The roll paper 5 is rotatably mounted on the supporting portion 4 of the cover 2, and the rotating shaft 6 between the blade 2a at the front of the cover 2 and the rear 2c of the cover is rotatably attached to the bearings 3 at both ends of the side plate 1b. The surface of the plate back 2 b of the cover 2 is in contact with and covers the roll paper 5.

The main body 1 is provided with a surface in contact with a wall and two left and right side plates 1b perpendicular to the surface. 2
A bearing 3 is provided at the tip of one side plate 1b, and the cover 2 is rotatably mounted on the main body 1.

The support portion 4 is a shaft without a core, a shaft rod with a core, a one-touch paper exchange holder type, etc., to which the roll paper 5 can be rotatably attached and detached.

The cover 2 has an arcuate surface that is warped in the opposite direction to the surface of the roll paper 5, and has a front blade portion 2a and a rear portion 2a.
and a rotating shaft 6 for attaching to the main body 1 between the main body 1 and the main body 1. When the paper is pulled out, the front blade 2a rises when the drawn paper is lifted, and the surface of the plate back 2b holds the roll paper 5 by the lever principle with the rotation shaft 6 as a fulcrum to prevent rotation and cuts the paper by the blade 2a. I do.

The resistance of the cover 2b can be increased by molding the surface of the back 2b of the cover 2 into an uneven or corrugated shape.

FIG. 3 is a diagram showing the contact area between the arc-shaped surface of the plate back 2b of the cover 2 and the paper of the roll paper 5.
The contact area increases because the cover 2 draws an arc.

FIG. 4 shows a state in which the roll paper 5 is brought into contact with the arc-shaped cover 2 by the drawing force of the paper.
FIG. 6 is a diagram illustrating a pressing force applied to the roll paper 5 by decomposing a force applied to the roll paper 5.

FIG. 5 is a diagram in which the self-weight is increased by extending the entire length from the rotating shaft 6 of the cover 2 to the cover rear portion 2c, and the rotation stopping force of the roll paper 5 is increased. FIG.

FIG. 6 shows that the distance between the blade portion 2a of the cover 2 and the rotating shaft 6 can be reduced by increasing the pressing force by the arc-shaped cover 2, so that the bearing 3 at the distal end is formed.
And the distance between the support portion 4 and the support portion 4 can be shortened. FIG. 4 is a diagram showing that the blade portion 2a of the shortened cover 2 rotates about the rotation shaft 6 as a fulcrum and does not contact the roll paper 5.

FIG. 7 is a view showing a space in which the roll paper 5 can be taken up and down by vertical lines.

FIG. 8 shows a type in which the arc-shaped surface from the rotating shaft 6 of the cover 2 to the rear portion 2c of the cover 2 is flat.

FIG. 9 shows a similar type of paper holder which can bend the plane of the cover 2 of FIG.

FIG. 10 shows that the arc-shaped cover 2 can generate a pressing force in the direction of the roll paper 5 by the drawing-in force (winding force) of the paper even when the amount of paper of the roll paper 5 is small. It is a figure showing a position.

[0023]

According to the roll paper holder of the present invention, the roll paper can be pulled out with one hand and cut off with one hand without touching the roll paper holder.
