Reference numeral 6 (see FIG. 3 and the like) denotes a paper removing unit for removing the cut paper 1 from the blade 3a. As shown in the drawing, the paper removing portion 6 has a substantially arc-shaped longitudinal section, and is formed at a position near the lower end of the lid 3 so as to protrude in a convex step shape on the back side of the lid 3.

A plurality of the rollers 4 are horizontally mounted in parallel. In the case of the present invention , specifically, the roller 4 includes the uppermost roller 4a rotated by the motor 5, the middle roller 4b disposed below the uppermost roller 4a, and the middle roller. It is comprised with the roller 4c of the lowest step arrange | positioned under 4b.

  In FIG. 3 etc., 7a, 7b is a pair of parallel guide rollers provided inside the front part of the lid 3. In the case of this embodiment, the uppermost roller 4a is provided in contact with the peripheral surface of the upper guide roller 7a, and the middle roller 4b is provided in contact with the peripheral surface of the lower guide roller 7b. Accordingly, in this case, since the drawing end 1a of the roll paper 1 is sandwiched between the guide rollers 7a and 7b and the belt 8, the paper is fed in close contact with the belt 8, and further generation of bending and slackening occurs. It can be suppressed.

In this embodiment, the lowermost roller 4c sandwiches the drawer end 1a of the roll paper 1 between the paper removal portion 6 and the belt 8 at a position corresponding to the paper removal portion 6, as shown in FIG. It is provided so that it can be sent out.
Therefore, according to this, it is possible to more reliably suppress the occurrence of bending and slack in the paper between the middle roller 4b and the lowermost roller 4c.

  Thus, the belt 8 that receives the roll paper 1 has a function of rotating together with the roller 4 and transmitting the rotational force as the paper is fed. As shown in FIG. 1, the belt 8 protrudes from the peripheral surface of the roller 4 in a convex step shape, and is connected to the uppermost roller 4a and the middle roller 4b, and the middle roller 4b and the lowermost roller 4c. 2 is symmetric when viewed from the front. In the case of this embodiment, specifically, the belt 8 is hung on the uppermost roller 4a and the middle roller 4b in a pair of left and right. The middle roller 4b and the lowermost roller 4c are installed in a total of four, two on the left and right sides.

  Reference numeral 9 (see FIGS. 1 and 3) denotes a vertical plate for preventing the paper from being caught inward. The vertical plate 9 is provided below the lowermost roller 4c with its upper end engaged with an annular groove 10 extending in the circumferential direction of the lowermost roller 4c.

  The motor 5 is composed of a reversible motor that can rotate forward and backward, and as shown in FIG. 1, the motor 5 is provided in the internal space S on the side of the main body 2 with the rotation axis facing upward. Reference numeral 11 denotes a drive switch for the motor 5. Reference numeral 12 (see FIG. 2) denotes a switch for setting the paper feed length of the motor 5. By operating this switch 12, the time for which the motor 5 rotates is set, and the paper 1 is sent out by a length corresponding to the driving time of the motor 5.

  Reference numeral 13 (see FIG. 4) denotes a pair of parallel support rods that support the roll paper 1. The support bars 13 are horizontally mounted on the lower part of the main body 2 along the arrangement direction of the cores of the roll paper 1 and in a state where the distance between the support bars 13 is smaller than the diameter of the cores of the roll paper 1. In the case of the present invention of this embodiment, the rear support bar 13 is formed by the link member 14 so as to be retractable within the range of the diameter of the roll paper 1 in conjunction with the opening operation of the lid 3. Reference numeral 15 denotes a slit formed in each side plate of the main body 2 in order to guide the end of the support rod 13 on the rear side. As shown in FIG. 1, each end portion of the rear support rod 13 protrudes into the internal space S and is connected to the end portion of the lid 3 via the link member 14. .

  Reference numeral 16 denotes a backing plate for the roll paper 1. The receiving plate 16 is horizontally mounted in a pair of front and rear sides on the side plate so that the peripheral surface of the roll paper 1 comes into contact therewith. Further, the receiving plate 16 is formed of a transparent acrylic plate in this embodiment so that the remaining amount of the roll paper 1 can be easily seen from the front of the main body 2 or the like. The roll paper 1 can be smoothly pulled out in a stable posture by the receiving plate 16.

Three protrusions 18 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.
Reference numeral 19 (see FIG. 2 and the like) is a paper receiver provided on the lower side of the main body 2 so as to be connectable to the main body 2. Further, 20 (see FIG. 1) is an optical sensor that detects the leading end 1a of the roll paper 1.

Next, the operation of the toilet paper holder of the present invention will be described.
First, when the user turns on the drive switch 11 of the motor 5, the motor 5 rotates for a preset time. When the motor 5 rotates, the uppermost roller 4a rotates. This rotational force is transmitted by the belt 8, and the middle roller 4b rotates. Since the middle roller 4b is connected to the lowermost roller 4c by the belt 8, when the uppermost roller 4a rotates, the middle roller 4b and the lowermost roller 4c rotate in the same direction together with the belt 8. To do.

  In the case of the present invention, the roll paper 1 is in contact with the belt 8 and is received by the belt 8, so that when the belt 8 rotates, the paper is a certain length (length of one time) due to friction with the belt 8. Only sent out. In particular, according to the present invention of this embodiment, the drawer end 1a is sandwiched between the guide rollers 7a and 7b and the belt 8, so that the drawer end 1a is closer to the belt 8 and is stably fed out. The fed paper 1 is folded on the paper receiver 19 and placed. Therefore, the user manually cuts the paper using the blade 3a of the lid 3.

  Thus, in the case of the product of the present invention, when the user cuts the paper with the blade 3a of the lid 3, the optical sensor 20 is turned on, and the motor 5 is driven to feed the paper by the length of one time. In the case of the present invention, when all the paper 1 is fed out to become only the core, the core is supported by the support bar 13 and remains in the main body 2 without dropping. And then, when the lid 3 is opened in this state, the link member 14 is pulled up as the end of the lid 3 rotates, and the support rod 13 on the rear side is guided to the slit 15 through the link member 14. It is lifted diagonally backward and moves backward. As a result, the distance between the support bars 13 becomes larger than the diameter of the lead, and the lead falls and is removed. The falling core is collected by the paper receiver 19 on the lower side of the main body 2.

  Thus, the user puts a new roll paper 1 into the main body 2 with the cover 3 fully open, puts the drawer end 1 a of the roll paper 1 on the belt 8, and pulls out a little forward. Close. As a result, the guide rollers 7a and 7b at the front portion of the lid 3 are pressed against the peripheral surface of the belt 8, the pull-out end 1a of the roll paper 1 is applied with pressure, and feeding is enabled.
