Description

[Detailed description of the invention] [Field of industrial application] This invention places a spare case containing a spare roll under the roll paper set in the main case, and simply rotates the spare case. , relates to a Watsutatsu-type paper holder that allows the roll paper to be replaced.

[Conventional technology]

For example, when the roll paper set in the paper holder runs out in a toilet or the like and it is replaced with a new one, the process is usually done as follows. First, prepare the spare roll by removing it from the place where it is being tossed. Then, the core rod set in the paper holder is removed from the holder together with the core of the used roll paper, the core rod is inserted into the core of the spare roll, and this is set in the paper holder. .

However, with this method, if the spare roll is stored in a place other than the toilet room, it may become impossible to replace the paper if it runs out during use, which is inconvenient.

Therefore, in the past,
As disclosed in the publication (see Figures 4 and 5),
A paper holder 1 having a storage space 3 for a spare roll 2 has been developed. This paper holder 1 has both side walls 4 and 5 and a back wall 6, and a support shaft 8 for a roll paper 7 that is rotatable upward from a horizontally protruding state on the upper inner surface of both side walls 4 and 5.
It has A cutout 9 for inserting a hand into the lower part of the space 3 in which the spare roll 2 is stored is formed. Therefore, paper holder 1
The front side of the roll is an open face 10 because it is necessary for the user to hold and set the spare roll 2 by hand.

[Problem that the invention attempts to solve]

However, the conventional paper holder 1 has
Since the entire front surface is an opening surface 10, the stocked spare roll 2 can be seen from inside the toilet room.
It looked bad. Further, dust sometimes entered through the opening surface 10 and adhered to the spare roll 2 or the inner wall surface of the storage space 3. Furthermore, the spare roll 2 has the disadvantage that it tends to fall from the opening surface 10 when the roll paper 7 is touched by a hand while in use. Furthermore, when setting the spare roll 2 to use, it is necessary for the user to hold the spare roll 2 by hand and push it upward to fit the support shafts 8, 8 into the center core 2a of the spare roll 2. Ta. That is, when setting the spare roll 2, it was necessary for the user to check whether the set state is reliable. This is because the entire front surface of the paper holder 1 is an opening surface 10, and the position of the center core 2a of the spare roll 2 tends to fluctuate in the front-rear direction because the paper holder 1 is set while being held by the user's hand. be.

[Means for solving problems]

The present invention improves and eliminates the above-mentioned problems of conventional paper holders, and provides a paper holder in which a spare roll can be reliably set simply by rotating the spare case upward. This is what I am trying to do.

Therefore, the means adopted by the present invention in order to solve the above-mentioned problems includes a main body case having both side walls and a rear wall, and an upper side of the inner surface of both side walls of the main body case, which is arranged upwardly from a horizontally protruding state. The roll paper support shaft is rotatably attached to the roll paper support shaft, and the spare case is rotatably pivoted to the front middle part of the inner surface of the both sides, and the spare case has a spare roll storage part. However, the rotation locus of the center core of the stored spare roll passes through the support shaft.

[Effect]

When the spare case rotatably attached to the main case is rotated upward, the outer circumferential surface of the spare roll stored in the spare case pushes up the core of the used roll paper, and at the same time Rotate the support shaft. Then, the core of the used roll paper is automatically removed from the support shaft. Subsequently, the support shaft is inserted into the center core of the spare roll. Next, when the spare case is rotated back downward in this state, the support shaft is rotated back to the horizontally protruding state, and the spare roll is set in a usable state. Since the spare case has been rotated back to its original position and is empty inside, it is sufficient to replenish it with new spare rolls.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below based on embodiments shown in the drawings.

1 to 3 relate to one embodiment of the present invention, in which FIG. 1 is a longitudinal sectional view showing the entire paper holder 11, and FIG. 2 is a longitudinal sectional view showing the entire paper holder 11.
FIG. 3 is an overall perspective view of the paper holder 11 showing the state of use. As shown in the figure, the paper holder 11 consists of a main case 12 and a spare case 13. Main case 1
2 has both side walls 14 and 15 and a back wall 16,
A support shaft 18 for the roll paper 17 is attached to the upper inner surfaces of the side walls 14 and 15, and is rotatable upward (upright position) from a horizontally protruding state. A paper cutting board 19 is rotatably attached to the upper end of the main body case 12 near the rear wall 16.

The spare case 13 has a J-shaped cross section, and the bottom thereof serves as a storage section 21 for the spare roll 20. This spare case 13 is rotatably attached to the middle portion of the front side of the inner surfaces of the side walls 14 and 15. Further, when the spare case 13 is rotated counterclockwise in FIG. 1 with the spare roll 20 stored therein, the rotation locus of the center core 20a of the spare roll 20 is set to the side walls 14 and 15. Its size is set so that it passes through the support shaft 18.

Further, a curved portion 24 is formed on the inner surface of the rear wall 16 of the main case 12 so as not to interfere with the rotational movement of the preliminary case 13. and,
A stopper 23 is attached to the lower central portion of the curved portion 24 and is biased to rotate counterclockwise in FIG. 1 by a torsion spring 22.

Next, the operation mode of the paper holder 11 configured in this way will be explained.

In normal use, the spare case 13 is locked by the stopper 23 and is in the position shown by the solid line in FIG.
0 is stored. Further, a roll paper 17 is rotatably supported on support shafts 18 attached to both side walls 14 and 15, so that the user can freely pull it out.

When the roll paper 17 runs out and needs to be replaced, the spare case 13 is pushed upward and rotated. As a result, the outer peripheral surface of the spare roll 20 stored in the spare case 13 comes into contact with the center core 17a of the used roll paper 17. Then, as the rotation of the spare case 13 progresses further, the spare roll 21 pushes up the used core 17a and at the same time rotates the support shaft 18 upward. That is, the support shaft 18 is placed in an upright position. For this reason,
The used core 17a comes off the support shaft 18,
fall naturally. Eventually, the center core 20a of the spare roll 20 comes to correspond to the tip of the support shaft 18, and the support shaft 18 comes to enter into the center core 20a of the spare roll 20 at this position.
After that, when the spare case 13 is rotated clockwise in FIG. Supported.

After that, the spare case 13 is rotated to the position shown by the dashed line in FIG. 1, and a new spare roll is loaded into the storage section 21. And spare case 13
What is necessary is to lock the distal end side of the stopper 23 to the stopper 23.

In this way, in this embodiment, preliminary case 1
The spare roll 20 stored in the spare case 13 can be reliably attached to the support shaft 1 by simply rotating the shaft 3 back and forth once.
8 and can be set. That is, there is no need for the user to set the spare roll while holding the spare roll and confirming that it is attached to the support shaft as in the past, and the roll paper can be replaced reliably and easily.

By the way, the present invention is not limited to the above-mentioned embodiment, but includes the main case 12 and the spare case 1.
The external shape, size, etc. of No. 3 can be changed as appropriate. Furthermore, explanation of the rotation mechanism of the support shaft 18 has been omitted because various rotation mechanisms can be applied.

[Effect of idea]

As explained above, in the present invention, by simply rotating the spare case containing the spare roll once back and forth, the core of the used roll paper is automatically removed from the support shaft, and the spare roll is moved to the support shaft. It is possible to set it to a usable state.
In that case, the size of the spare case is
Since the rotation locus of the center core of the spare roll is set to pass through the support shaft, it is possible to reliably attach the center core of the spare roll to the support shaft. Furthermore, since the spare case itself serves as a cover for the spare roll, the overall appearance is good and dust does not adhere to the spare roll or the like.
