An arm extends from the tip of the rotary top cover, and a pressing roller is rotatably supported at the tip of the arm, and the pressing roller is in contact with the pull-out roller.
Paper extending from the toilet paper resting on the support is sandwiched between the draw roller and the pressure roller, and the paper is drawn from the roll when the draw roller is rotated by a motor. Here, the pressing roller pivotally supported at the tip of the rotary top cover is in pressure contact with the pull-out roller so as to pinch the paper.

On the other hand, the holder of the present invention can also be constructed with a cutter capable of cutting the stretched paper to an appropriate length. A pull-out roller is provided in the vicinity of the tip of the rotary top cover at a predetermined distance from the rollers constituting the support, and an intermediate roller is arranged between the pull-out roller and the above-mentioned rollers.
A presser roller and an intermediate presser roller are pivotally supported on an arm extending from the tip of the rotary top cover. When the rotary top cover is closed, the presser roller contacts the pull-out roller and the intermediate presser roller contacts the intermediate roller. I can. The cutter is arranged between the pull-out roller and the intermediate roller, and is configured to cut the paper by sliding (raising) the cutter.

The toilet paper holder of the present invention has a supporting portion composed of two rollers arranged in parallel with a predetermined interval, and the rolled toilet paper can be set on the supporting portion. In other words, there is no shaft core to be inserted into the center shaft hole, and it can be set easily and correctly just by placing it on the support portion composed of two rollers.

The paper pulled out from the roll is sandwiched between the pull-out roller and a pressing roller pivotally supported at the tip of the rotary top cover, and the roll is rotated by the rotation of the pull-out roller to pull out the paper.
In this case, in the present invention, the rollers constituting the support portion are rotated by the motor, and the pull-out rollers that sandwich the paper and are pulled out are also rotated. A minute is drawn out.
In addition, by installing the holder of the present invention in the toilet, the opportunity to touch each part of the toilet paper is suppressed, and infection with various bacteria is prevented.
