Description

  The present invention relates to an apparatus related to drawing and cutting of roll paper such as toilet paper and kitchen paper.

Conventionally, a roll paper retainer is supported horizontally using a shaft using a hole in the center of the roll paper. Also, in order to prevent the roll paper from rotating naturally, etc., it is common to place a cover with one end hinged on the top of the roll paper and give friction so that it does not rotate naturally due to its own weight. Is. Not only the weight of the lid but also a light spring presses it.
Some cutting means have a blunt cutter at the free end (tip) of the lid.

When using paper, it is necessary to grasp, pull out and cut the end of the roll paper. However, the end of the roll paper is often hidden inside the back (back) of the lid or is in close contact with the outer periphery of the roll paper, and the other hand can lift the lid or idle the roll paper It was necessary to explore and grab the edge.

After grasping the end of the roll paper, pull out the necessary length, cut it for use, but if you pull the paper to try to cut it, the lid will lift up against its own weight and spring, making it difficult to cut the paper , Often out of necessity. For this reason, in cutting, it was necessary to pull out the paper while assisting (fixing) with the other hand so that the lid does not lift or the roll paper does not rotate.
In addition, from the idea that the cutter is dangerous, there are many cases where there is no cutter if the aesthetics of the cut end and ease of cutting are not concerned.

That is, there is an inconvenience in grasping and pulling out the end portion of the roll paper with one hand and cutting it into a necessary length, and it is particularly difficult when the body is inconvenient.

In the past, there have been applications for inventions and devices that address these problems. Many of these inventions focus on either paper gripping and drawing (for example, Japanese Patent Application Laid-Open No. 2007-105327) or cutting methods (for example, Japanese Patent Application Laid-Open No. 2001-37673). There is also a device for both gripping, pulling out and cutting (registered utility model publicity 3058898), but the structure is complicated, the roll paper supply set before use is complicated, paper pulling resistance is large, and smooth drawing is difficult, paper Since the end is exposed on the upper surface of the plate, it is easy to be displaced, and it is easy to receive dust, and it is feared that the cutter is exposed on the upper part of the front surface and gives a dangerous feeling.
