Braking means for releasably braking the rotation of the turning part.

Thus, when the user unwinds the roll sheet and pulls the unwound portion so as to press it against the friction surface or the cutting blade, the swinging member swings to rotate the winding portion of the roll sheet. Brake.

At this time, the tension applied to the unwinding portion is reduced on the rear side by rubbing against the friction surface or the cutting blade. That is, the tension applied to the front side of the unwound portion from the portion engaging with the friction surface is larger than the rear side. For this reason, it cut | disconnects in the part which engages with a cutting blade, or the front side, and is not cut | disconnected at the back side.

Here, the force by which the braking means brakes the rotation of the winding portion of the roll sheet is substantially proportional to the force by which the user pulls the unwinding portion against the friction surface or the cutting blade. In order for the user to be able to brake the rotation of the winding part when pulling the unwinding part, the friction coefficient between the unwinding part and the friction surface or the cutting blade is appropriately large, and the braking means is used for the winding part.

The braking means can be engaged with the upper part of the winding part.
Thereby, when the unwinding part is engaged with the friction surface or the cutting blade and is tensioned, the braking means presses the winding part from above to downward to brake.

Here, since the swinging member can swing vertically, the braking means can further increase the force for braking the rotation of the winding portion by the mass of the swinging member itself.
Thereby, cutting can be performed more reliably by the user pulling the unwinding portion. Of course, the same effect can be obtained by using the spring force of the spring instead of the braking effect by the mass of the swinging member.

In the roll sheet cutting device of the present invention, in a preferred embodiment, at least the cutting edge of the cutting blade can be protruded and retracted, and when the blade is protruded, it can be engaged with the unwinding portion.

Thus, when the user pulls the unwinding portion of the roll sheet to press against the friction surface or the cutting blade, the cutting edge of the cutting blade protrudes, and if not, the cutting edge is immersed. Injury to a finger or the like can be prevented.

In a preferred embodiment, the roll sheet holder of the present invention includes any one of the roll sheet cutting devices described above.

The user can unwind the roll sheet provided with the roll sheet holder by pulling the unwind portion with one hand and cut the roll sheet into a predetermined or arbitrary length. In particular, the roll sheet cutting device of the present invention, even when the roll sheet is a fragile toilet paper,
The effects of the present invention can be remarkably exhibited.

In a preferred embodiment, the adhesive tape holder of the present invention extends forward from behind the winding portion of the adhesive tape and is swingably supported behind the winding portion of the adhesive tape. The swinging member, the adhesive receiving surface provided at the front portion of the swinging member and capable of adhering the adhesive surface of the unwinding portion of the adhesive tape, and the unwinding portion of the adhesive tape provided at the intermediate portion of the swinging member. When the adhesive member is adhered to the adhesive receiving surface and tightened, the swinging member swings in a predetermined direction to brake the rotation of the winding portion of the adhesive tape so that it can be released, and the unwinding portion of the adhesive tape is engaged. A possible cutting blade.

When tension is applied to the unwinding portion of the adhesive tape by pulling the adhesive surface of the unwinding portion of the adhesive tape to the adhesive receiving surface and pulling the unwinding portion, the unwinding portion of the unrolled portion of the adhesive sheet is subjected to a friction surface Alternatively, the same effect as when tension is applied by pulling against the cutting blade is obtained. For this reason, the adhesive tape can be easily cut into an arbitrary length. In particular, even with an adhesive tape having a weak adhesive force, a favorable effect is exhibited.

In a preferred embodiment of the pressure-sensitive adhesive tape holder of the present invention, at least the cutting blade is capable of protruding and retracting, and can be engaged with the unwinding part when the cutting blade protrudes.

When the user unwinds the adhesive tape by a necessary length and pulls the adhesive surface while adhering the adhesive surface to the adhesive receiving surface, the swinging member swings in one direction, and the cutting blade protrudes to cause the adhesive tape to protrude. Can be cut. Further, when the user does not pull the adhesive tape, the swinging member swings in the other direction, so that the cutting blade is immersed and can be handled safely.
