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 can be 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. let 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 return to the horizontal state due to 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 also had the disadvantage of becoming larger, making the whole thing larger.

[Means for solving problems]

The present invention improves and eliminates the above-mentioned conventional problems, and aims to provide a compact one-touch type paper holder whose height can be kept to a minimum. .

The means adopted by the present invention to solve the above-mentioned problems is a paper holder which is attached to the inner side of both side walls of a holder body having both side walls and a rear wall, and which is equipped with a bearing shaft which, when setting the roll of paper, can be inserted into the central core of the roll of paper after it has first moved away from the roll of paper. The holder comprises a bearing shaft which is arranged so as to be able to protrude and retract within both side walls, an L-shaped arm which is arranged straddling both side walls and the rear wall, and a slider which is located in the centre of the rear wall and partly protrudes towards the front side of the rear wall and is able to slide freely in the front-to-rear direction, one end of the L-shaped arm is connected to the bearing shaft and the other end is attached to the slider via a long hole, and its intermediate bent portion is pivotally connected to the holder body.

[Effect]

When setting the roll paper, first pull the slider toward you (in the direction in which it protrudes from the back wall of the holder body) and place it. As a result, the support shaft side of the L-shaped arm rotates about the pivot in the expanding direction, and the support shaft moves into the side wall of the holder main body. When the roll paper is brought close to the back wall of the holder main body from this state, the outer peripheral surface of the back side of the roll paper comes into contact with the slider, and the slider moves the L-shaped arm towards the back wall of the holder body. rotate in the opposite direction. As a result, the support shafts attached to one end of the L-shaped arm are moved in a direction in which the distance between the support shafts becomes narrower, and they protrude from the inner surfaces of both side walls. Then, it enters the core of the roll paper and supports the roll paper in a freely rotatable manner.

In this way, with the paper holder of the present invention, it is possible to set the roll paper simply by pushing it into the back wall of the holder body.
