However, in the case of this conventional product, for example, serrated teeth were provided at the lower end of the front part of the lid, and when the roll paper was cut with this blade, the cut end of the paper entered between the blades, and the paper stuck to the blade It was easy to be in a state.
Therefore, according to the conventional holder of this type, there is a problem that the paper is easily clogged at the base of the blade on the back side of the lid and the paper cannot be smoothly fed out.
Japanese Patent No. 3396834

The present invention has been proposed in view of such problems of the prior art.
Therefore, the technical problem to be solved by the present invention is that the paper feeding can be automated by the motor, the fall of the roll paper core is prevented by a pair of parallel support rods when the paper runs out, and the core is interlocked with the opening / closing operation of the lid. An object of the present invention is to provide a roll paper holder formed so that paper can be smoothly and reliably fed out by preventing the paper from clogging at the base of the blade on the back side of the lid in the roll paper holder formed so as to be able to fall and collect. .

The present invention employs the following technical means in order to solve the above problems.
That is, as shown in FIG. 1 and the like, the present invention includes a main body portion 2 in which the roll paper 1 is accommodated with the core 1a sideways, and a lid 3 that closes the upper surface of the main body portion 2. On the front side, a roller 4 that comes into contact with the front portion 3a of the lid 3 is laid horizontally along the direction in which the core 1a of the roll paper 1 is disposed. 3 is provided in the main body 2, and a pair of parallel support rods 10 that support the roll paper 1 are arranged below the main body 2 along the arrangement direction of the core 1 a of the roll paper 1, and The support rods 10 are horizontally mounted with the interval between the support rods 10 being smaller than the diameter of the core 1a of the roll paper 1, and the rear support rod 10 is retracted within the diameter range of the roll paper 1 in conjunction with the opening operation of the lid 3. Roll paper paper that is freely formed A blade 15 for cutting the roll paper 1 is formed at the lower end of the front portion 3a of the lid 3, and the blade 1 of the paper 1 after cutting is separated from the root of the blade 15 on the back side of the lid 3 The paper removal portion 17 is formed in a convex curve shape toward the back side of the lid 3, and the motor 5 is configured as a reversible motor. The controller 19 is provided with a controller 19 that rotates and controls the feeding of the roll paper 1 (Claim 1).

  Here, in a state smaller than the diameter of the core 1a of the roll paper 1, even if all the paper is sent out and the roll paper 1 becomes only the core 1a, as long as the lid 3 is not opened, the core 1a is a support bar. 10 means that falling is prevented. In the range of the diameter of the roll paper 1, when the lid 3 is opened and a new roll paper 1 is put into the main body 2, the roll paper 1 is supported and stored by the support rod 10 without dropping. Means. In the case of the present invention, if the paper removing portion 17 is formed in a convex curve toward the back side of the lid 3, it is formed at the lower end of the front portion 3a of the lid 3 over the entire length in the left-right direction. It is not limited to. That is, the paper removing portion 17 is formed, for example, at the base of the blade 15 on the back side of the lid 3 to have a certain length in the left-right direction, or in the form of a bowl (sphere) with a certain interval in the left-right direction. It may be formed in a shape in which a part of is cut. Here, “instantaneous” means, for example, about 0.3 to 0.5 seconds. The length of the paper to be rewound is about 5 to 10 mm. Examples of the roll paper 1 include toilets and kitchens.

Thus, in the present invention, it is preferable that the blade 15 is bent outward (claim 2).
Because, according to this, the paper 1 can be cut from the paper removing portion 17 to the blade 15 in a state of being curved in a convex curve toward the back side of the lid 3. This is because it becomes difficult for the paper 1 to enter between the two, and the blades of the paper 1 can be separated well.

Further, according to the first or second aspect of the present invention, the support member 21 for the coreless roll paper disposed between the pair of parallel support rods 10 at the lower side of the both side walls of the main body 2 is freely raised and lowered. (Claim 3).
Because, according to this, even if the diameter of the coreless roll paper 1 becomes smaller than the distance between the pair of support bars 10 as the paper is pulled out, the coreless roll paper 1 can be used up to the end without dropping. It is.

Thus, in the case of the present invention, it is preferable that the coreless roll paper support member 21 is housed by being submerged in the side wall of the main body 2 when standing up.
This is because in this case, the side surface of the roll paper 1 does not come into contact with the upright support member 21, so that the support member 21 can be prevented from adversely affecting the drawer of the roll paper 1.

The present invention thus forms a blade for cutting the roll paper at the lower end of the front part of the lid, and a paper removal part for improving the separation of the paper after cutting at the root of the blade on the back side of the lid. A controller that is formed in a convex curve toward the back of the lid, and the paper feeding motor is a reversible motor. When this motor is started, the motor is reversely rotated momentarily and then rotated forward to control the roll paper feed. Are formed.
Accordingly, in the case of the present invention, the cutting edge of the paper cutting edge is improved, and the cutting edge can be unwound slightly before being sent out. According to this, the paper can be smoothly fed without clogging the back side of the lid. And reliably.

  Reference numeral 24 (see FIG. 1, FIG. 2, etc.) is a protrusion for receiving the side surface of the roll paper 1. Three protrusions 24 are formed in parallel on the inner surface of the side wall of the main body portion 2 in the longitudinal direction in this embodiment. Thereby, the roll paper 1 is prevented from coming into surface contact with the inner surface of the side wall, the contact frictional resistance is reduced, and the roll paper 1 is smoothly rotated and pulled out. Further, in this embodiment, the protrusion 24 is formed so that the front surface is inclined so as to become higher inward of the main body portion 2 as it goes downward. Therefore, according to this, since the outer peripheral edge of the side surface of the roll paper 1 is supported by being in contact with the lower portion of the protrusion 24, the contact friction during rotation is further reduced and the roll paper 1 is drawn out smoothly.

Next, the operation of the roll paper holder of the present invention will be described.
First, the drive switch 9 of the motor 5 is turned on. Then, in response to the signal from the controller 19, the motor 5 rotates reversely for a set time of 0.3 seconds and then rotates forward. The rotational force of the motor 5 is transmitted to the worm 7, and the worm 7 is converted into a rotation about the horizontal axis by the worm wheel 8 around the rotation axis 5 a, and the worm wheel 8 is attached. The existing roller 4 rotates. Accordingly, when the motor 5 rotates in the forward and reverse directions, the roller 4 is rewound once by the friction with the paper 1 and then the roll-out end 1b of the roll paper 1 which is cut by the blade 15 and arranged at the back side position of the blade 15 is moved forward. To a certain length. The unwinding length is about 5 mm in this embodiment. The fed paper 1 is manually cut from the position of the blade 15. In this case, since the blade 1 is bent outward in this example, the paper 1 is cut along the curve of the blade 15 without strongly biting between the serrated teeth, and the paper removal portion. It is naturally removed from the blade 15 by 17 bulges.

  In the case of the present invention, when all the paper 1 is sent out to become only the core 1a, the core 1a is supported by the support rod 10 and remains in the main body 2 without dropping. Next, when the lid 3 is opened in this state, the link member 11 is pulled up with the rotation of the end 3c of the lid 3, and the rear support rod 10 is guided to the slit 13 through the link member 11, It is lifted diagonally backward and moves backward. As a result, the interval between the support bars 10 becomes larger than the diameter of the core 1a, and the core 1a is dropped and removed. It is preferable that the falling core 1a is collected in the storage unit by providing a storage unit for the spare roll paper 1 on the lower side of the main body unit 2, for example.

  Thus, the user puts a new roll paper 1 into the main body 2 with the lid 3 fully opened. In the case of the product of the present invention, the backward distance of the support rod 10 on the rear side is selected within the range of the diameter of the roll paper 1 as described above. Therefore, the roll paper 1 put into the main body 2 is supported by the pair of support rods 10 and stored in the main body 2 without dropping. Then, the user puts the drawer end 1 b of the roll paper 1 on the roller 4 and slightly pulls forward, and closes the lid 3. Then, the link member 11 pivotally attached to the end 3c of the lid 3 is pushed down, and the rear support rod 10 is guided by the slit 13 to move forward and return to the original position. As a result, the roll paper 1 is stably supported by the pair of support rods 10, the guide roller 3b of the front portion 3a of the lid 3 is pressed against the peripheral surface of the roller 4, and the drawer end 1b is interposed via the guide roller 3b. Then, the pressure is applied at the front portion 3a of the lid 3, and the roller 4 can be rewound and fed out.

Further, in the product of the present invention, when the roll paper 1 without a core is used, the support member 21 is tilted inward, and the support member 21 is disposed substantially horizontally between the pair of support bars 10. In this state, as in the case of the above example, the coreless roll paper 1 is put into the main body 2 and the drawer end 1b is set. In the product of the present invention, even when the coreless roll paper 1 is used, even if the diameter becomes smaller than the distance between the pair of support bars 10, it is supported by the support member 21 and can be used up to the end.
The product of the present invention is not limited to the case where it is attached to the wall surface of a toilet, but may be attached to the wall surface of a kitchen, for example, and used to pull out roll-shaped kitchen paper.
