Next, a method of using this embodiment configured as described above will be explained.

First, an unused towel 38 is attached to the cassette 2.

Since the unused towel 38 is already wrapped around the supply roller 39, the shafts 39a at both ends of the supply roller 39 are fitted into the elongated holes 34.

Next, the tip of the unused towel is pulled out, passed through the outside of the guide bar 37, the front side of the bottom plate 31, the bottom of the bottom plate, and the gap 32, and then passed through the take-up roller rotatably supported in the notch 35. Wrap around 40 several times.

At this time, the unused towel pulled out is made to form the optimum loop length L.

Next, the fixture 41 is attached, but at this time, first press the large arc-shaped part 42 onto the upper side of the unused towel 38 located above, and then press the small arc-shaped part 4
4 together with the towel onto the winding roller 40, and the guide bar 37 is fitted together with the towel between the projecting pieces 45, 45.

When the fixture 41 is attached in this way, the fixture 41 is attached to the guide bar 3 by the projecting pieces 45, 45.
7 to the cassette 2 side, and the large and small circular arc parts 42 and 44 are elastically pressed against the unused towel 38 and the take-up roller 40, and the unused towel 38 and the take-up roller 40 are moved toward the cassette side. Fixed to.

With the unused towel attached, the cassette 2 is packaged in a plastic film bag or shrink-packed and delivered to the user.

The user unpacks the package and attaches the cassette 2 to the main body 1 of the dispensing machine fixed to the wall.

At this time, the cassette 2 is placed opposite the main body with the support frames 29 and 30 facing the main body, and the protrusion 33
on the upper side of the protruding piece 8, and the lower surface of the support frame 30 on the support frame 9.
Press fit into the main body 1 so that it is positioned above the main body 1.

Then, the protrusion 13 of the lock lever 11 is pressed against the outside of the side plates 28, 28, and the lock lever 11 is elastically deformed outward.

Then, when the protrusion 13 eventually passes over the side plate 28, it fits into the notch 36, and the cassette 2 is locked.

At this time, the spring 15 provided on the back plate 6 is elastically deformed and compressed.

Unused towels can be attached together with the cassette in one operation as described above.

When the cassette 2 is installed, the protrusion 46 of the fixture 41 hits the front edge of the top plate 5 of the main body 1,
The unused towel 38, the winding roller 40, and the guide bar 30 are removed from between the large and small arcuate portions 42, 44 and the projections 45, 45, and the fixture 41 is automatically removed.

In this state, the user wipes his hands using the front side of the looped unused towel, and after use, pulls the front side of the looped towel downward.

At this time, a downward load is applied to the unused towel, but since the axis of the unused towel and the axis of the drive rollers 3 and 4 are misaligned, no load is applied perpendicular to the axis of the drive roller 3. The weight at the time of pulling out functions as a rotational moment for the unused towel 38, and the towel is reliably pulled out.

At the time of pulling out this towel, there are 38 unused towels.
is in contact with the drive roller 3, the drive roller 3 is rotated, the drive roller 4 is rotated via the gears 24 and 25, the winding roller 40 in contact with this is rotated, and the used towel is wound up. .

When the amount of used towels to be wound increases, the diameter of the used towels wound around the winding roller 40 increases, and the drive rollers 3 and 4 are pushed up through the elongated hole 16, but the drive roller 3 is always unrolled. It is in contact with the used towel 38.

Therefore, an amount of used towel corresponding to the amount pulled out is wound up, and the loop length L is always kept approximately constant.

Use continues in this manner, and when all the unused towels are used up, the cassette 2 is removed and replaced with a new one.

In this case, push the front ends of the lock levers 11, 11 outward with your fingertips to remove the protrusion 13 from the edge of the notch 36 of the cassette 2.

Then, the spring 15 provided on the back plate 6 of the main body 1 extends and pushes the edges of the support frames 29, 30, so that the cassette 2 is pushed forward a predetermined distance.

After being pushed out a predetermined distance, the side plate 28 of the cassette
28, pull it out from the main body 1, and replace it with a new cassette 2 as described above.

Note that the replaced used towel may be attached with the fixture 41 upside down to prevent it from rotating, and then returned by placing it in a plastic film bag or the like.

It should be noted that the present invention is not limited to the above embodiments, but includes within its scope various modifications, design changes, etc. without departing from the technical idea of the present invention.

[Effect] As is clear from the above description, according to the present invention, the unused towel is placed on the upper side of the cassette that is detachably attached to the main body side, and the take-up roller around which the used towel is wound is placed on the lower side. Because the towel is installed in a cassette, it is extremely hygienic and easy to put on and take off.Since the unused towel is located at the top, it is possible to remove germs from the used towel side. There will be no inconveniences such as objects falling.

In addition, by using a fixture, it is possible to hold unused towels and take-up rollers so that they do not rotate, and the loop can be supplied in a constant state, making it extremely easy to handle before installation or after removal. becomes.
