Description

[Detailed description of the invention] [Industrial application field] The present invention is capable of automatically loading the roll paper into the core after once avoiding the roll paper with one simple operation when setting the roll paper. This invention relates to a so-called one-touch type paper holder equipped with a support shaft that can be used.

[Conventional technology]

A conventional one-touch type paper holder of this type is shown in FIGS. 4 to 6. As shown in the figure, the conventional paper holder 1 includes a holder body 2, side walls 3 of this holder body 2,
It consists of supporting shafts 5, 5 for the roll paper 4 attached to the inner side of the roll paper 3, a paper cutting board 6, and a back wall 7. The back side of the holder main body 2 has an opening surface 8, and the insides of both side walls 3, 3 are hollow. A cylindrical bearing portion 9 is formed in this cavity to which one side of pins 5a, 5a formed on both sides of the rear end portions of the support shafts 5, 5 is pivotally attached. Also, both side walls 3, 3
On the inner surface side, there is a notch 1 that communicates with the opening surface 8.
0 is formed. On the other hand, a cylindrical bearing part 11 is formed protruding from the back plate 7 to pivot the other side of the pins 5a, 5a of the support shafts 5, 5, and at a position corresponding to the notch part 10, An upright wall 12 is provided to partially close the notch 10. The support shafts 5, 5 protrude from the notches 10, 10 of the side walls 3, 3, with the pins 5a, 5a fitted and pivotally attached to the bearings 9, 11 (see FIG. 5). Furthermore, tongue pieces 13, 13 are formed on the lower surfaces of the rear end sides of the support shafts 5, 5 to apply elastic force separated by slits. Furthermore, as shown in FIG. 4, U-shaped grooves 14 are formed in the upper portions of the side walls 3, 3 on the rear plate side, for pivotally mounting the pins 6a, 6a of the paper cutting board 6.

In the conventional paper holder 1 configured as described above, the roll paper 4 is replaced by moving the roll paper 4 from the state shown in FIG. 5 from the bottom to the top as shown by the arrow in FIG. 6. . As a result, the outer peripheral surface on the upper end side of the roll paper 4 becomes
The support shafts 5, 5 are pushed up and rotated upward around the pins 5a, 5a, and the support shafts 5, 5 are retracted into the side walls 3, 3 of the holder main body 2. Due to this rotational retraction movement, the tongue pieces 13, 1 of the support shaft 5
3 is bent by contacting the inner wall surfaces of the side walls 3, 3, and applies elastic force to the support shafts 5, 5. When the center core 4a of the roll paper 4 comes to a position corresponding to the tip of the support shafts 5, 5, the support shafts 5, 5 automatically move into the center core 4a due to the elastic force of the tongue pieces 13, 13. Charge to. If you let go of the roll paper 4 in this state, the weight of the roll paper 4 and the tongue piece 1 will increase.
The support shafts 5, 5 are rotated back to the horizontal state by the elastic forces 3, 13, and rotatably support the roll paper 4. That is, the user can freely pull out the roll paper 4.

[Problem that the invention attempts to solve]

However, in the conventional paper holder 1, when setting the roll paper 4,
Since the support shafts 5, 5 rotate into and out of the side walls 3, 3 of the holder main body 2 and become in an upright state, the height dimension of the both side walls 3, 3 is smaller than the dimension of the support shafts 5, 5. It had the disadvantage that it became larger and the whole thing became larger. In addition, as a dimension to reduce the height dimension of both side walls 3, 3, it is possible to lengthen the dimension between both side walls 3, 3, but in this case, the width dimension of the paper holder 1 will increase, and the overall size will also increase. ization was inevitable.

[Means for solving problems]

The present invention improves and eliminates the above-mentioned conventional problems, and aims to provide a compact one-touch paper holder whose height, width, etc. can be minimized. It is something.

Therefore, the means adopted by the present invention to solve the above problem is attached to the inner side of both side walls of a holder main body having both side walls and a rear wall, and when setting the roll paper, the device is attached to the inner side of the both side walls, and when setting the roll paper, In a paper holder equipped with a support shaft that can be automatically inserted into the core of the roll paper after performing an avoidance operation, the support shaft is rotatably attached to the inner surface of both sides, and the tip of the support shaft is The thick wall portion can be inserted into the core of the roll paper, and the base of the support shaft is a thin wall portion that allows the thick wall portion to escape upward from the upper end surface of the side wall of the holder main body.

[Effect]

When setting the roll paper, when the roll paper is moved from below to above the support shaft, the outer peripheral surface of the upper end of the roll paper first comes into contact with the support shaft and pushes it upward. Therefore, the support shaft rotates upward from the horizontally protruding state and becomes an upright state, and the thick end portion is located above the upper end surface of the side wall of the holder body and avoids the roll paper. Therefore, it is possible to reduce the width dimension of the holder main body by the dimension located above. Of course, unlike the conventional case in which the support shaft is retracted into the side wall, the height of the side wall can also be reduced.

When the roll paper continues to move upward and the core reaches the thick-walled portion at the tip of the support shaft, the support shaft is automatically inserted into the core.
In this state, when the hand is released from the roll paper, the support shaft rotates back to the horizontally protruding state due to the weight of the roll paper, etc., and rotatably supports the roll paper. That is, it is possible to freely pull out the roll paper.
