Abstract

PROBLEM TO BE SOLVED: To easily deliver a roll paper by anyone by pressing a non-slip member to the roll surface of the roll paper, and mounting, on the non-slip member, a reverse rotation preventing tool rotatable only in the drawing direction of the roll paper and performing a braking operation in the opposite direction. SOLUTION: A roller 5 is pressed onto the roll surface of a roll paper 9 through an arm 4 energized by a spring 7. When the paper tip part 9a of the roll paper 9 is pushed out, the roller part 5c of the roller 5 is rotated in an arrowed direction Y, and the roll paper 9 is also rotated in an arrowed direction X so as to be freely drawable. Since the roller part 5c of the roller 5 is engagingly locked by an inner wheel 5a fixed to the arm 4 side so as not to be rotatable, when the roll paper 9 is apt to be rotated in the opposite direction by any reason, the roller part 5c pressed onto the roll surface acts as a brake to arrest the rotation of the roll paper.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments will be described below in order to clarify the configuration and operation of the present invention described above.

In FIG. 1 and FIG. 2, a support 1 having an opening at the front side and having a substantially U-shaped side wall 1a is formed of, for example, a resin member. In order to support the support shaft 2 on which the roll paper 9 is mounted and held, a bearing hole b is formed symmetrically. Furthermore,
The support 1 has opposed bearing holes 1c at predetermined positions on the upper side of the left and right side walls 1a. Further, at a predetermined position of the side wall 1a on the base side which forms a mounting surface of the support 1 to a wall surface or the like, the arm 4 is supported so as to be vertically swingable.
The mounting surface 1d, which is arranged side by side, and the holding surface 1e, which holds the mounting of the spring 7 for applying a predetermined pressing force to the arm 4, are opposed to each other and protruded. In the center of the mounting surface 1d and the holding surface 1e, a shaft hole 1f through which a mounting pin 8 for supporting the arm 4 and the spring 7 is fitted is formed so as to communicate therewith. A receiving surface 1g, which serves as a lower limit stopper of the arm 4 that swings up and down, protrudes below the mounting surface 1d, and stops the lowering of the arm 4 when the roll paper is completely used up.

The support shaft 2 has a length and a thickness corresponding to the width of the roll paper and the hole of the shaft core, respectively, and has a shaft portion 2a inserted into the bearing hole 1b of the support 1 at both end surfaces thereof. Is protruding.

The cover 3 has a curved surface at the front end so as to cover the upper surface of the roll paper 9, and the front end is lightly in contact with the roll surface of the roll paper to enable paper cutting at the end surface. Mounting shafts 3a are symmetrically protruded from both side surfaces of a base end on the mounting side to the support 1. Thus, the cover 3 is provided with the bearing hole 1 c of the support 1.
Can be mounted to swing up and down.

The arm 4 is formed of, for example, a resin member or the like. A shaft hole 4b into which the mounting pin 8 is loosely inserted is formed in one base end 4a. The other end is bifurcated into a U-shape so as to rotatably hold the roller 5, and the end 4 c is formed to communicate with a square hole 4 d for supporting the roller 5. .

The roller 5 is an example of a non-slip member. A square hole 5b is formed in the center of the roller 5, and an inner ring 5a is fixed to the tip 4c of the arm 4.
The roller portion 5c, which is mounted on the outer periphery of the inner ring 5a and forms an outer ring, and the roller portion 5c, which forms an outer ring, are freely rotatable in one direction. And has a so-called one-way clutch function. The outer peripheral surface of the roller portion 5c forming the outer ring is formed of, for example, a rubber member or a resin member having a rough surface so as to form a predetermined frictional resistance when pressed against the roll paper. Is provided.

The roller 5 is provided at the tip 4 of the arm 4.
c is attached to square c with square pins 6. That is, the inner ring 5 a of the roller 5 is fixed to the arm 4 via the square pin 6.

The spring 7 is constituted by a torsion spring having a predetermined wire diameter, inner diameter and number of turns, and both ends thereof form arms 7a and 7b of a predetermined length, respectively. The tips of the arms 7a and 7b are each bent in an L-shape in a predetermined direction. Thus, the spring 7 is mounted on the support 1.
The base end portion 4a of the arm 4 to which the roller 5 is simultaneously mounted is provided between two mounting surfaces protruding side by side between the holding surface 1e protruding from the side wall 1a on the base side and the mounting surface 1d opposed thereto. 1
d, the mounting pin 8 is inserted from one side, and the spring 7 and the arm 4 are attached to the support 1.
Attached to. Further, one arm 7a of the spring 7 mounted on the mounting pin 8 is fitted into a hole 1h provided on the support 1 side, and the tip of the other arm 7b is twisted as shown by a broken line in FIG. The force is applied and the arm 4 is locked to the back.

FIG. 2 is an explanatory view showing a longitudinal section in a state where the roll paper 9 is mounted on a paper holder made of the above-mentioned components. That is, the roller 5 is pressed against the roll surface of the loaded roll paper 9 via the arm 4 urged by the spring 7. Here roll paper 9
When the paper tip 9a is pulled out, the roller portion 5c of the roller 5 rotates in the direction of arrow Y, and at the same time, the roll paper 9 rotates in the direction of arrow X and can be drawn freely.
However, if the roll paper 9 is rotated in the opposite direction for any reason, the roller portion 5c of the roller 5
Is locked to the inner ring 5a fixed to the arm 4 side,
Since the roller cannot rotate, the roller portion 5c pressed against the roll surface acts as a brake to prevent the roll paper from rotating.

FIG. 3 shows another embodiment of the non-slip member. That is, in FIG. 1, this is another embodiment in which the roller 5 serving as a non-slip member is replaced, and the form of the arm 4 is also changed accordingly. That is, the anti-slip member 10
Is composed of an arm portion 11 and a brake portion 12, and a shaft end 11b is formed in a base end portion 11a of the arm portion 11 so as to be attached to the support 1 by the attachment pin 8, and the other end is formed. On the side, a brake portion 12 having a curved surface of a predetermined area is provided.
The outer end surface of the brake portion 12 is pressed against the roll surface of the roll paper 9, and the outer end surface has the leading end portion 9 of the paper of the roll paper 9.
The arrow x direction, which is the direction in which a is drawn out, is the first order,
In the opposite direction, a brushed sheet 12a which is turned in the opposite direction is attached. Thus, the non-slip member 10 is urged by the spring 7 to press the roll surface of the roll paper 9, and has no effect on the withdrawal of the leading end of the paper, and does not affect the rotation in the opposite direction. In other words, the brushed sheet serving as a bark acts as a brake to prevent rotation.

[0021]

Since the present invention is configured as described above, it has the following effects.

Since the roll paper mounted on the paper holder is constantly pressed by the non-slip member of the reverse rotation preventing device, the leading end of the paper is always at a predetermined position, and it is difficult to take out or cut the paper. It can be used easily by anyone without the need for consideration, and various secondary problems can be resolved. Since it can be applied to various types of paper holders, the range of application is expanded, and highly versatile products can be provided. In addition, since the non-slip member is constituted by the rotor or the brushed sheet for the brake section, there is a specific effect that the operation is smooth.
