The lower side of the roller small diameter portion 22 formed by the roller 21 is passed through. As a result, the upper presser guide member 23 remains in a fixed position even when the drive roller 9 and the presser roller 19 rotate, and the toilet sheet roll 7 fed out by the drive roller 9 and the presser roller 19 is moved between the drive roller 9 and the presser roller. 19. Therefore, the configuration is such that the sheet roll 8 can be set simply by placing it on the U-shaped groove 42. The sheet roll 8 can be easily replaced. Also, when replacing the sheet roll 8, the presser roller 19 is inserted into the fitting groove 4.
5, it can be easily attached and detached. First of all, since it is structured like this. One end of the toilet paper roll 7 wound around the sheet roll 8 is inserted between a pair of rollers, the drive roller 9 and the presser roller 19, which are in pressure contact with each other, and the upper presser guide member is rotated by hand by rotating the drive roller 9. 23.28 and the lower support guide member 12, and send it out onto the guide member 39. After that, the toilet sheet roll 7 is slightly pulled out from between the pair of rollers 9 and 19, and the lid 3 of the toilet bowl 100 is removed.
Close. Thereafter, when the lid 3 of the toilet bowl 100 is opened and released as shown in FIG. 7, the claw 33 attached to the lid 3 of the toilet bowl 100 pushes the engaged ratchet gear 15 and the second Rotate as shown by arrow E in the figure. Then, the drive gear 16 rotates in response to the rotation of the ratchet gear 15, and the rotation of the drive gear 16 causes the gear 13 to rotate. The rotation of this gear 13 causes one drive roller 9 of the pair of rollers 9 and 19 to rotate, and the toilet sheet roll 7 sandwiched between the two rollers 9 and 19 moves between the toilet seat 2 and 19 as shown in FIG. sent to. The ratio between the number of gears of the drive gear r6 and the number of gears of the gear 13 is determined by rotating the two rollers 9 and 19 by the 1 drive gear 16, which rotates by one rotation of the 5-chain end gear 15. The ratio is such that the drive roller 9 can be given enough rotation to send the toilet seat 2 to a fixed position on the toilet seat 2. Therefore, by opening the lid 3 of the toilet bowl 100 once, the toilet sheet roll 7 can be placed in a fixed position on the toilet seat 2 as shown in FIG. Further, when the lid 3 of the toilet bowl 100 is closed, the pawl 33 slides on the gear of the ratchet gear 15, and the ratchet gear 1
Since it does not mesh with gear 5, it spins idly. That is, the ratchet gear 15 does not rotate due to the action of the pawl 33. Therefore, the toilet sheet roll 7 held between the two rollers 9.19 is not sent in the direction opposite to the direction in which it is sent out by the two rollers 9.19, that is, in the retracted direction. Furthermore, the claw 33 when the lid 3 of the toilet bowl 100 is closed
Rotation of the ratchet gear 15 due to the movement of is prevented. In addition, for example, when a boy urinates standing up and does not sit down on the toilet seat 2, the toilet sheet roll paper 7 may be placed on the toilet seat 2 by the closing operation of the lid 3 of the toilet bowl 100. When there is no need to feed the paper, the pawl 33 and the ratchet gear 1 are released using the paper feed release lever (not shown).
5. When the engagement between the claw 33 and the ratchet gear 15 is released by this paper feed release lever,
Even when the lid part 3 of the toilet bowl 100 is opened and closed, the toilet sheet roll paper 7 is not sent out onto the toilet seat 2. When the lid 3 of the toilet bowl 100 is opened and closed together with the toilet seat 2, the lid 3 is opened and closed while the paper feed release lever is pressed on the top surface of the toilet seat 2. The roll paper 7 is not sent out onto the toilet seat 2.
