Abstract

PROBLEM TO BE SOLVED: In a conventional roll paper holding and cutting apparatus, even when a paper end serving as a grip margin is secured and exposed after cutting, the paper end hangs down.
For desktop use, the fact that the paper edge hangs down is not suitable for miniaturization and ease of use. Furthermore, the operation direction for drawing and cutting the paper is not the downward direction, but the horizontal or upward direction is suitable.
[Solution]
The present invention comprises a holder capable of smoothly pulling out roll paper, a cutting device that exposes a paper end as a grip allowance after paper cutting, and a guide means for guiding the paper end forward. Provided is a small roll paper holding and cutting device that can be easily grasped at the end and easily pulled out and cut.

Description

  The present invention relates to an apparatus for pulling and cutting roll paper, and mainly relates to a roll paper holding and cutting apparatus used by being placed on a table.

Conventionally, roll paper is often used by being accommodated in a container or rotatably supported using a hole in the center of the roll, and attached to a wall surface.
Cutting by pulling out the paper is generally based on a cutter provided at the free end (tip) of the lid. However, since the cutter attached to the lid moves lightly during cutting, the paper is unnecessarily drawn out, and it is difficult to cut with one hand. In addition, the paper edge after cutting is hidden behind the lid and the cutter, and there is a difficulty that it is difficult to use because the grip for the next drawer is not exposed.
Further, in a small apparatus intended for use on a desktop, it is not appropriate to pull down the paper even when it is pulled out or cut.

Examples of an invention that attempts to solve the above-mentioned difficulties, “paper cutting” and “next gripping allowance” include “JP 2001-37674” and “JP 2008-36201”. All of these inventions are based on the assumption that they are fixed to a wall or placed on a table.
In the former invention, since a roll paper holder that is used while being fixed to a wall surface is used for a desktop, a support (support leg) is provided, and miniaturization is not considered. When cutting the paper, it is drawn downwards, which may be one of the factors that hinder downsizing.
Judging from the mechanism, I don't think I can secure a sufficient grip.

In the latter invention, a box-type holder for accommodating roll paper is shown as an example of a desktop type. Also in this invention, when it cuts, it has pulled down substantially, The distance to a table top surface is short, and it cannot be denied that it is difficult to use.
Further, in order to secure a gripping margin, a “paper cutting portion” that is a cutter protrudes forward of the holder by a length corresponding to the gripping margin. Therefore, the cutter is closest to the user, and there is a fear that the cutter may give a dangerous feeling.

The present invention adopts a cutting device of the invention of Patent Document 3 (not disclosed, the applicant is the same as the present inventor) described later, and is an improved roll paper holding and cutting device so that it can be used on a desktop. Is to provide. Below, the outline of patent document 3 is described.

1, 2, and 3 are one design example based on Patent Document 3. FIG.
FIG. 1 is a front view (partial cross-section), FIG. 2 is a side cross-sectional view, and FIG. 3 is a cross-sectional view for explaining a state during paper cutting. In any of the drawings, the paper and the heper roll are indicated by imaginary lines (two-dot chain lines). The upper half of FIGS. 2 and 3 is a holder 111 that supports a paper roll, and the lower half is a cutting device 120 that cuts paper.
The paper roll support shaft 112 fixed to the right side plate 114 is inserted with a central hole of the paper roll 100 (illustrated by phantom lines and shaded) to support the paper roll 100. 113 is a retaining plate for preventing the paper roll from coming off, and is fixed to the tip of the paper roll support shaft 112. Usually, the right side plate 114 is fixed to the wall.

An A width plate 122 and a B width plate 123 are fixed to a position below the right side plate 114. The lateral length (width) of both the A and B width plates 122 and 123 is slightly longer than the width of the paper roll 100 (usually 114 mm). The left side plate 121 is fixed to the end portions of the A and B width plates 122 and 123 opposite to the right side plate 114.
A turning shaft 129 is provided below the A width plate 122, and a stopper receiver 130 is provided above. The cutting plate 124 is attached by a cutting plate boss 127 and a cutting plate shaft 126 so that it can be rotated lightly between the right side plate 114 and the left side plate 121.
The upper end of the cutting plate 124 is a stopper 128, and an anti-slip material is affixed to the inner surface of the stopper 128. There may be no anti-slip material.
A blunt cutter 125 is provided at the lower end of the cutting plate 124.

Normally, as shown in FIG. 2, the paper 101 (shown in phantom) passes through the outer side of the stopper receiver 130 (right side in FIG. 2) and hangs down through the inner side of the turning shaft 129 (left side in FIG. 2). The end 102 is exposed.
After grasping the paper end 102 and pulling out the paper of a required length, the paper is pulled in the front and front in a substantially horizontal direction, the paper 101 and the cutter 125 are entangled, and the cutting plate 124 is rotated. When pulled further upward, the stopper 128 comes into contact with the stopper receiver 130. (See Figure 3)
In this state, the paper is cut diagonally and horizontally. Immediately after, the cutting plate 124 is rotated by gravity, and the cutter 125 returns to the original position close to the turning shaft 129. At the same time, the paper edge 102 hangs downward and is exposed, returning to the state shown in FIG.

If the paper drawing resistance is sufficiently large, the paper 101 may pass through the inside of the stopper receiver 130 (left side in FIG. 2). In this case, the initial paper set is somewhat easier.
In the present invention, the part to which Patent Document 3 is applied bears a cutting method including a turning shaft 129, a cutting plate 124, a cutter 125, a stopper 128, a stopper receiver 130, and the like, and a function of exposing the paper edge after cutting. Cutting device.
Several inventions that deal with the above-mentioned difficulties withdrawing / cutting are shown below. The present invention particularly relates to Patent Document 3.

JP 2001-37674 A JP2008-36201A Japanese Patent Application No. 2012-158374

In the following, the portion of the roll paper that is wound in a cylindrical shape is a roll or paper roll, the portion that is rewound therefrom is simply paper, and the end of the paper that corresponds to the gripping margin is the paper end.
Moreover, the functional part which supports and hold | maintains a roll so that rotation is possible is made into a holder, and the functional part cut | disconnected so that a grip allowance is ensured after cutting | disconnection is made into the cutting device.

The present invention is a roll paper holding and cutting device in which a paper end serving as a grip allowance for drawing is exposed at the same time that the paper is drawn and cut, and is characterized by being mainly placed on a table and used. Since the paper is placed on the table, the paper edge is not suspended but exposed on the guiding means for guiding the paper edge. Because it is used on a desktop, the method of pulling the paper downward cannot be used. Furthermore, the present invention provides a roll paper holding and cutting apparatus that takes into account the fact that initial setting of paper and paper rolls is easy, the cutter does not give a dangerous feeling, and that a compact design is possible.
It is also possible to use it fixed on a wall surface or the like.

The present invention employs the following means for solving the above-described problems.
That is, as described in claim 1,
A paper roll holder that enables smooth drawing of paper and use on a table, a cutting device that exposes the paper edge that is used to hold the drawer at the same time the paper is cut, and tilts the paper edge. A roll paper holding and cutting apparatus, comprising: guide means fixed to the holder for exposing the roll paper.

As claimed in claim 2,
2. The roll paper according to claim 1, wherein when inserting and setting the paper, between the guide means and the cutting device , one of left and right sides can be opened and closed with the side of the cutting device as an axis. Holding cutting device.

As claimed in claim 3,
The anti-reverse means for pressing the paper against the guide means in order to prevent the paper end exposed on the guide means from being drawn and hidden. Roll paper holding and cutting device.

One feature of the roll paper holding and cutting device of the present invention is that it is small and can be used on a table. Simple configuration and mechanism, easy initial setting of paper roll and paper, and easy paper pull-out. There is a feature that a paper end as a gripping margin is formed on the guide means and exposed at the same time as a paper having a required length is pulled out and cut.
In usage, it competes with tissue paper that is folded and stored in a paper box, but roll paper is cheaper and can be used by cutting it to any length (size), so there is no waste and other effects large.

In the following embodiments, the guiding means employs an inclined plate “oblique plate”, and therefore the guide means is simply referred to as an oblique plate.
The reference numerals of the constituent elements in each figure are partly overlapped for correspondence with other figures.
The first embodiment is shown in FIGS.
Since the right side of FIG. 4 is the front surface, FIG. 4 is a left side view. The paper roll 40 (shaded), the paper 41, and the paper edge 42 are indicated by imaginary lines (thin two-dot chain lines).
FIG. 5 is a right side view (part), and particularly shows a state in which the cutting device 20 and the holder 1 are attached by the hinge 17 and the hinge clasp 18.
FIG. 6 is a plan view (viewed from above). The shape of the lid 2 is not rectangular, and the width of the portion that is rotatably supported is about half the maximum width of the lid 2, in other words, the distance between the right support plate 8 and the left support plate 13. This is to facilitate insertion of the paper 41 unwound from the paper roll 40 between the cutting device 20 and the holder 1.
FIG. 7 is a front view (viewed from the front). The space visible in the lower center is the notch 10a of the diagonal plate 10 and the notch 9a of the base plate 9 below the notch 10 to facilitate gripping the paper end 42 (not shown in FIG. 7).
FIG. 8 is a side sectional view. The arrangement state of most related elements is specified.

The holder 1 will be described with reference to FIGS.
On the base plate 9, the right support plate 8 and the left support plate 13 are fixed vertically with a gap (full width) slightly wider than the width of the paper roll 40 (about 114 mm). A paper roll support bar 6 is horizontally fixed to the right support plate 8 in a cantilever shape. A fastening plate 7 is fixed to the other end of the paper roll support bar 6 as a retaining of the paper roll 40.
A lid support bar 4 is fixed in a cantilever manner above the right support plate 8, and a shaft bar joining plate 5 is fixed to the other end. A lid shaft 3 that rotatably supports the lid 2 is supported by a right support plate 8 and a shaft rod joining plate 5. As described above, the width of the support portion of the lid 2 is about half of the total width in order to facilitate the setting of the paper 41.

An oblique plate 10 is fixed between the right support plate 8 and the left support plate 13. In the vicinity of the upper extension of the surface of the diagonal plate 10, a stopper receiver 11 is rotatably attached by a stopper receiving shaft 12. The stopper receiver 11 also has a function of smoothly changing the flow direction of the paper 41 while receiving the stopper 28. Accordingly, a rotatable roller is preferable, but a shaft that cannot rotate if there is little friction with the paper may be used, or the upper edge of the oblique plate 10 may be smoothly finished and integrated.
As described above, as shown in FIGS. 7 to 8, the oblique plate 10 is provided with the notch 10 a, the base plate 9 is provided with the notch 9 a, and the paper end 42 exposed on the oblique plate 10 is provided. It is easy to grasp.

As shown in FIGS. 8 and 9, the skeleton of the cutting device 20 is configured by connecting and fixing a right plate 21 and a left plate 22 with a width plate 23.
As shown in the right side view of FIG. 5, a hinge 17 is fixed to the right support plate 8 and the right plate 21 of the cutting device 20 by a hinge retaining nail 18. Therefore, the right plate 21, that is, the cutting device 20 can be opened and closed with respect to the right support plate 8 for the purpose of facilitating the insertion set of the paper 41. (See Figures 10-11)

As shown in FIGS. 4 and 6, an L-shaped fastener 15 is rotatably attached to the left plate 22 by a shaft pin 16. When the L-shaped fastener 15 is anchored to the retaining pin 14 provided on the left support plate 13, the cutting device 20 is integrally closed with the retainer 1, that is, the left and right support plates 13 and 8.

In the cross-sectional view shown in FIG. 8 (paper and paper roll are not drawn), a turning shaft 24 is fixed to the right plate 21 and the left plate 22 below the extension of the width plate 23 of the cutting device 20. The surface of the turning shaft 24 may have a low friction and may be a roller that is rotatably supported by the right plate 21 and the left plate 22.

As shown in FIG. 8 and the like, a cutting plate shaft 27 supported by the right plate 21 and the left plate 22 is provided above the extension of the width plate 23, and the cutting plate 25 is smoothly rotated via the cutting plate boss 26. Is supported so that
A cutter 30 is provided at the lower end of the cutting plate 25. The cutter 30 is not sharp and may be a resin or wood having smooth serrated irregularities.
The upper end of the cutting plate 25 is a stopper 28, and a non-slip 29 is stuck on the inner surface side. When the anti-slip 29 and the stopper 28 come into contact with the stopper receiver 11, the cutting plate 25 cannot be further rotated. Further, the paper 41 between the stopper 28 and the anti-slip 29 (stopper receptacle 11) is easily cut by being restricted from being further pulled out. The anti-slip 29 may not be provided.

9 is a cross-sectional view taken along the line BB in FIG.
A mating surface (line) between the holder 1 and the cutting device 20 is shown.
It is also shown that the paper roll support shaft 6, the stopper receiver 11, the turning shaft 24, the width plate 23, the cutting plate shaft 27, the anti-slip 28, etc. are parallel to each other.
It is shown that the right support plate 8 and the right plate 21 and the left support plate 13 and the left plate 22 are in close contact with each other.

FIG. 10 is a drawing in which a paper roll 40 (shaded and opaque) and a paper 41 (part) are added to FIG. Moreover, the cutting device 20 has shown the open state. The paper 41 is set through the space 43 between the holder 1 and the cutting device 20.

FIG. 11 is a cross-sectional view (partial) taken along the line CC in FIG. 10, and is redrawn with FIG. 8 in a state in which the heap roll 40 is set, the cutting device 20 is opened, and the paper 41 is set. If cutting device 20 is closed, it will be in a normal state.

FIG. 12 is a view in which the heap end 42 is pulled out in a substantially horizontal direction and in an arrow 44 direction. The paper 41 and the cutter 30 are not in contact yet.

FIG. 13 shows a state where the paper end 42 is pulled in the upward direction, in the direction of the arrow 45, the cutter 30 and the paper 41 come into contact with each other and are entangled, and the cutting plate 25 is rotated. A stopper 28 (anti-slip 29) is in contact with the stopper receiver 11 with the paper 41 interposed therebetween.
Neither the paper 41 nor the cutting plate 25 moves further. At this time, the paper 41 is cut by the cutter 30 when the paper end 42 is pulled diagonally upward and laterally.

As shown in FIG. 14, when the paper 41 is cut, the cutting plate 25 is rotated by gravity or the like, and the cutter 30 and the turning shaft 24 return to the original state. At the same time, the paper edge 42 is exposed on the oblique plate 10. The return force is not limited to gravity, and an elastic body such as a spring may be used.

The paper edge 42 exposed along the oblique plate 10 may be reversed by the wind or the like and hidden inside.
FIG. 15 shows a retrograde prevention means for preventing the paper edge 42 from going backward.

FIG. 15A is a drawing of FIG. 11, and FIG. 15B is a drawing of FIG. 14, in which an elastic plate 46 constituting the retrograde prevention means is added. FIG. 15C is an enlarged view of the vicinity of the elastic plate 46.
One end of the elastic plate 46 is a fixed end 48 bonded to the width plate 23. The boundary position of the fixed end 48 is bent plastically. Accordingly, the free end (pressing portion) 48 of the elastic plate 46 in the natural state is sufficiently separated from the width plate 23.
Note that a virtual line D in FIG. 15C is a mating surface between the holder 1 and the cutting device 20.

As shown in FIGS. 15B and 15C, when the cutting means 20 is closed, the free end 48 of the elastic plate 46 lightly presses the paper 41 against the surface of the oblique plate 10.
The pressing by the elastic plate 46 does not interfere with the pulling out of the paper 41, but the free end (pressing portion) 48 is self-excited (positive feedback) with respect to the reverse (drawing) of the paper 41. It works like a bite and prevents retrograde.

The above retrograde prevention means is not always necessary, and is effective for use in a place with wind such as a fan.

A second embodiment will be described with reference to FIGS.
The second embodiment also includes a holder 50 and a cutting device 65.
The support of the paper roll 76 is not a shaft support type but a box type. Any type of support may be used in the present invention.
When the support is a box type, the pull-out resistance is slightly larger than the shaft support type of the first embodiment. Since the paper roll 76 becomes lighter as it is consumed, the pull-out resistance changes. A measure such as placing a weight in the hole in the center of the paper roll 76 may be taken as appropriate.

FIG. 16 is a left side view (partial sectional view). Reference numeral 54 denotes a lid shaft that supports the lid 53 bent in a “h” shape so as to be freely opened and closed, and is supported by the left side plate 51 and the right side plate 52. A fastener that keeps the lid 53 in a closed state is necessary, but it may be a common one such as an L-shaped fastener, a magnet, or a hook-and-loop fastener, and is not shown.
The bottom plate 55, the left side plate 51, the right side plate 52, the front plate 56, and the oblique plate 57 serving as guide means are fixed integrally. Accordingly, the holder 50 has a container shape with the lid 53 on the rear surface.

The cutting device 65 is the same as the cutting device 20 of the first embodiment.
An L-shaped fastener 61 is rotatably attached to the left side plate 51 of the holder 50 with a shaft pin 62. The L-shaped fastener 61 is anchored to a retaining pin 60 provided on the left plate 67 of the cutting device 65, so that the holding tool 50 and the cutting device 65 are kept closed. Compared with the first embodiment, the positions of the retaining pin 60 and the shaft pin 62 are opposite, but there is no particular reason or difference.

FIG. 17 is a side sectional view including the paper roll 76.
A notch 57 a is provided at the lower end of the oblique plate 57 to facilitate gripping the paper end 78. As in the first embodiment, a stopper receiver 58 is provided above the oblique plate 57.

A right plate 66 and a left plate 67 (see FIG. 19) are connected and fixed by a width plate 68 to form a skeleton of the cutting device 65.
Below the extension of the width plate 68, a turning shaft 69 is provided that is sandwiched between the right plate 66 and the left plate 67 and changes the direction in which the paper 77 flows out.
The width plate 68 and the turning shaft 69 may be integrated, and the lower end of the width plate 68 may be smoothly finished to perform the function of the turning shaft 69. Further, the turning shaft 69 may have a rotatable structure in order to reduce the drawing resistance of the paper 77. The same applies to the first embodiment.

A cutting plate shaft 71 is attached between the left and right plates 67 and 66 at a position above the width plate 68. The cutting plate 70 is supported by a cutting plate boss 72 fixed to the cutting plate 70 so that the cutting plate 70 can be rotated lightly through the cutting plate shaft 71.

  A blunt cutter 75 is provided at the lower end of the cutting plate 70. A cutter that is safe to touch with fingers is desirable. (Refer to the first embodiment)

The upper end of the cutting plate 70 is a stopper 73 with an anti-slip 74 attached to the inner surface side. The slip stopper 74 may not be provided, but if it is present, the drawing out of the paper 77 is more reliably stopped.

A hinge (not shown as the second embodiment) as shown in FIG. 5 of the first embodiment is attached to the right side plate 52 side, and as in FIGS. 10 and 11 of the first embodiment, The cutting device 65 can be opened and closed.

After the lid 53 is opened and the paper roll 76 is inserted, the cutting device 65 is opened and the paper 77 is inserted and set as in the first embodiment. After setting so that the heper end 78 is sufficiently on the oblique plate 57, the cutting device 65 is closed and anchored by the L-shaped fastener 61. Thereafter, the lid 53 is closed. (See Figure 17)

The usage method will be described with reference to FIG.
First, the paper end 78 is grasped and a necessary length is pulled out almost horizontally. Thereafter, when the pulling direction is upward as indicated by an arrow 63, the paper 77 and the cutter 75 are entangled and the cutting plate 70 is rotated and inclined. The stopper 73 (slip stopper 74) is in contact with the stopper receiver 58 with the paper 77 interposed therebetween. The cutting plate 70 or the like does not rotate any further.
If the paper is pulled slightly diagonally while maintaining the above state, the paper is cut. The meaning of “pulling slightly diagonally” indicates that the entire width of the paper is not cut at the same time, but sequentially cut from the right or left edge of the paper. This is the same as when cutting paper with a ruler-like object, or with scissors.
After cutting, the cutting plate 70 is rotated by gravity or the like, and returns to the original position where the turning shaft 69 and the cutter 75 are close to each other. The paper edge 78 is exposed on the slanting plate 57, and further protrudes from the diagonal plate 57, thereby making a grip allowance.

FIG. 19 is a perspective view seen from the front left upper direction. In order to show the shape of the lid 53, it is drawn in an open state. The notch 57a in the slanted plate at the center of the slanted plate 57 is for making it easier to grip the paper end 78.

As described above, the guiding means in these embodiments is a “slanting plate”, but is not limited to a plate. A bar in which bars are arranged vertically or horizontally or a mesh-like plate may be used.
Also, the turning shaft may be a rotatable roller, or the lower end of the width plate of the cutting device may function as the turning shaft.
