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 plate 6, and a back plate 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 back 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 about 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 rotate back to the horizontal state due to the elastic forces of 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 also had the disadvantage of becoming larger, making the whole thing larger. Also, as a way to reduce the height of both side walls 3, 3, it is possible to lengthen the distance between both side walls 3, 3, but in this case, the width of the paper holder 1 will increase, resulting in a large overall size. 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, it is possible to remove the roll paper once from the roll paper. In a paper holder equipped with a support shaft that can be automatically inserted into the core of a roll paper after performing an avoidance operation, a recess into which the support shaft can retreat is formed on the inner side of both side walls of the holder body, and the recess is A long hole in the vertical direction is formed in the inner wall of the support shaft, a pin formed protruding from the side surface of the rear end of the support shaft is inserted into the long hole in the vertical direction, and a long hole in the horizontal direction is formed in the middle part of the support shaft. A pin fixed to the inner wall of the recess is inserted into the horizontal elongated hole, and the support shaft is biased in the projecting direction by a spring or the like.

[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 moves downward while the horizontal elongated hole in the intermediate portion is guided by a pin fixed to the holder main body, and the pin at the rear end is guided by the longitudinal elongated hole in the holder main body. As a result, the support shaft moves diagonally downward. When the core of the roll paper comes to a position corresponding to the tip of the support shaft, the support shaft is inserted into the core by the urging force of a spring or the like, and supports the roll paper rotatably.

In this way, the rear end (base) of the support shaft of the present invention retracts diagonally downward and performs an evasive action against the roll paper, so the height of both side walls of the holder body can be shortened, and the overall height can be reduced. It is possible to make it more compact.
