Abstract

PROBLEM TO BE SOLVED: To facilitate setting work of a recording paper roll in a machine glazed paper printer. SOLUTION: The tip 12a of a recording paper 12 is joined to the outer periphery of the recording paper roll 10 via a leader member 13. The leader member 13 is partitioned to an adhering part having a peelable adhesive and a non- adhering part, and made of an elastic material. In a package body, the non- adhering part bents along the outer periphery of the recording paper roll 10. When the recording paper roll 10 is extracted from the package body, the non-adhering part on the tip side stands up toward the tangential direction of the recording paper roll 10. When the recording paper roll 10 is set in a color heat-sensitive printer, the recording paper 12 is fed into a conveying passage with the leader member 13 in the lead. In the initial time of the feeding, the leader member 13 joined to the tip 12a of the recording paper 12 is peeled from the outer periphery of the recording paper roll 10.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording paper roll used for a roll paper printer or the like.

[0002]

2. Description of the Related Art In a roll paper printer, a recording paper roll is used in which a long recording paper is wound around the outer periphery of a core to form a roll. The recording paper portion is cut by a cutter immediately before or immediately after printing. Make a sheet.

Since the recording paper roll is obtained by simply winding a long recording paper around the core, if the leading end of the recording paper is not fixed to the outer periphery of the recording paper roll, the winding will be loosened. For this reason, as proposed in, for example, Japanese Patent Application Laid-Open No. 10-16454, there is a method in which the leading end of the recording paper and the outer periphery of the recording paper roll are fixed with a seal tape in order to prevent winding looseness. In this case, when the recording paper roll is set in the roll paper printer, the seal tape is peeled off, and the recording paper roll is set while pressing the leading end of the recording paper so as not to loosen.

[0004]

However, according to the method disclosed in Japanese Patent Application Laid-Open No. H10-16454, when the recording paper roll is set on the roll paper printer, the sealing tape fixing the leading end of the recording paper is peeled off. However, since the recording paper roll must be set on the roll paper printer while holding down the leading end of the recording paper, there has been a problem that the setting work is troublesome. In addition, there is a disadvantage that if the user forgets to peel the seal tape and sets the seal tape, the setting operation itself must be performed again.

When a recording paper roll is set in a roll paper printer, it is necessary to pull out the recording paper from the recording paper roll and pass the leading end of the recording paper through a transport path. However, when the rigidity of the recording paper used is low, there is a problem that jamming is likely to occur when the leading end is passed through the conveyance path.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a recording paper roll that simplifies the work of setting a recording paper roll on a roll paper printer and does not cause jamming.

[0007]

In order to achieve the above object, a recording paper roll of the present invention uses a resilient leader member in a recording paper roll formed by winding a long recording paper into a roll shape. The leader member is divided into an adhesive portion provided with a peelable adhesive layer and a non-adhesive portion not provided with an adhesive layer, and this adhesive portion is joined to the leading end of the recording paper and onto a recording paper roll to record. In addition to preventing the paper roll from being loosened, the non-adhesive portion that is separated from the recording paper roll in the free state is set to be the leading end when the recording paper is fed.

It is preferable that the width of the leader member is smaller than the width of the recording paper and the leader member is colored in a different color from the recording paper. Further, it is preferable that both sides of the non-adhesive portion are cut off obliquely and have a substantially triangular shape.

In addition, in a recording paper roll in which a long recording paper is wound into a roll shape, both sides of the leading end of the recording paper are cut off to form a substantially triangular shape, and the leading end of the triangle is folded inward to increase rigidity. In order to prevent loosening of the roll of recording paper, the inner surface of the outermost winding wound slightly from the leader and the outer surface of the inner part of the roll are partly used to prevent loosening of the roll of recording paper. It is also possible to use an adhesive that is adhesively bonded. In this case, it is preferable to form a U-shaped notch so as to surround the portion where the adhesive is applied.

Further, in a recording paper roll in which a long recording paper is wound in a roll shape, both sides of the leading end of the recording paper are cut off to form a substantially triangular shape. In order to prevent the recording paper roll from becoming loose, the inner surface of the outermost winding that has entered slightly from the leader and the inner part of it are partially adhered to prevent the recording paper roll from becoming loose. It may be bonded with an agent.

Further, in a recording paper roll in which a long recording paper is wound in a roll shape, both ends of the leading end of the recording paper are cut off to form a substantially triangular shape, and a substantially center line of the triangular shape becomes a peak or a valley. To slightly increase the rigidity,
The leader section is used as the top when the recording paper is sent out.In order to prevent the recording paper roll from becoming loose, the inner surface of the outermost winding that has entered slightly from the leader section and the outer surface of the inner part of the winding are partially It may be bonded with an adhesive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a recording paper roll 10 comprises a core 11 made of paper or plastic, and a long recording paper 12 wound around the core 11. . The recording paper 12 has a cyan thermosensitive coloring layer on a support,
This is a known color thermosensitive recording paper in which a magenta thermosensitive coloring layer and a yellow thermosensitive coloring layer are sequentially provided. The recording paper roll 10 is stored in a package such as a box or a bag having moisture retention and light shielding properties when not in use, and is taken out of the package when used.

A sheet-like leader member 13 is attached to the leading end 12a of the recording paper 12. The leader member 13 holds the recording paper 1 in a conveyance path of a thermal printer described later.
The second end portion 12a is used to guide the front end portion 12a, and the front end portion is cut into a tapered triangle, and is colored with a different color to be distinguishable from the recording paper 12. Also, the leader member 1
3 is made of a flexible, rigid plastic material, for example polyethylene terephthalate (PET). For this reason, when the recording paper roll 10 is stored in the package, the leader member 13 is curved along the outer periphery of the recording paper roll 10, and when the recording paper roll 10 is removed from the packaging, the recording paper roll 10 is moved. 10 protrudes substantially in the tangential direction.

The leader member 13 is arranged at a position shifted toward the side end of the recording paper 12 in order to clarify the loading direction of the recording paper roll 10. And the leader member 13
It can be seen that if the recording paper 12 is closer to the left than the center in the width direction of the recording paper 12 shown in the figure, the loading direction is correct, and if the leader member 13 is closer to the right, the loading direction is incorrect. In addition,
The direction and position in which the leader member 13 is shifted toward the end of the recording paper 12 may be determined as appropriate.

As shown in FIG. 2, the leader member 13 is divided into an adhesive portion 13a on which a peelable adhesive 14 is layered and a non-adhesive portion 13b on which the adhesive 14 is not layered. The adhesive portion 13a is provided at the leading end 12 of the recording paper 12.
a and the outer periphery of the recording paper roll 10. As a result, the leading end 12a of the recording paper 12 is fixed to the outer periphery of the recording paper roll 10, and the loosening of the recording paper roll 10 is prevented.

As shown in FIG. 3, the recording paper roll 10 is
The color thermal printer 18 is used by being set. The color thermal printer 18 includes a printer body 19 and the loading lid 2.
0. The printer main body 19 is provided with a paper supply unit 21, and the recording paper roll 10 is loaded in the paper supply unit 21. The paper supply unit 21 is provided with a holding member 22, and the recording paper roll 10 is rotatably held by the holding member 22 from both ends. Loading lid 20
Is connected to the printer main body 19 via the hinge 23 (see FIG. 4).

A bracket 20a is provided on the inner peripheral surface of the loading lid 20, and an upper pull-out roller 24 is rotatably mounted on the bracket 20a.
As shown in FIG. 4, the printer body 19 is provided with a lower draw-out roller 25, on which the leading end of the non-adhesive portion 13b of the leader member 13 is placed.
Then, when the loading lid 20 is closed, the leading end portion of the leader member 13 is nipped between the loading lid 20 and the upper draw roller 25.

As shown in FIG. 5, the recording paper roll 10 loaded in the paper supply unit 21 is provided with a pair of pull-out rollers 24 and 2.
The sheet is drawn into the conveyance path by 5 and sent to the conveyance roller pair 29. The transport roller pair 29 is a capstan roller 30
And a pinch roller 31 pressed against the capstan roller 30. Lower draw roller 2
5 and the capstan roller 30 are rotationally driven by a transport motor 32, thereby causing the recording paper 12 to reciprocate.

A thermal head 33 and a platen roller 34 are arranged between the pair of pull-out rollers 24 and 25 and the transport roller pair 29 so as to sandwich the transport path.
The thermal head 33 is disposed below the transport path,
The heating element array 33a is provided. Heating element array 3
As is well known, 3a is formed to be long in the direction orthogonal to the transport direction of the recording paper 12, and is configured by arranging a plurality of heating elements in a line. The platen roller 34 is disposed above the transport path at a position facing the heating element array 33a. The thermal head 33 is movable vertically, and is urged by a spring (not shown) in a direction in which the thermal head 33 comes into pressure contact with the platen roller 34.

A yellow fixing lamp 35 and a magenta fixing lamp 36 are provided at the exit side of the conveying roller pair 29. The yellow fixing lamp 35 has an emission peak of almost 4
The magenta fixing lamp 36 is an ultraviolet lamp having an emission peak of approximately 365 nm. Then, the recording paper 12 is reciprocated at the thermal head 33 by the conveying roller pair 29,
The yellow image, magenta image, and cyan image are thermally recorded and light-fixed by a three-pass method.

A cutter 37 is provided downstream of the magenta fixing lamp 36. The cutter 37 cuts the recording paper 12 drawn from the recording paper roll 10 into a sheet. When the recording paper roll 10 is set, the leading end portion 12a of the recording paper 12 is precut to separate the leader member 13 from the recording paper 12. The cut recording paper 12 is discharged out of the printer through the recording paper entrance 38.

Next, the operation of the present embodiment will be described. When the recording paper roll 10 is packed in a package, the non-adhesive portion 13b of the lead member 13 is pressed against the outer periphery of the roll. When the recording paper roll 10 is taken out of the package, since the leader member 13 is formed in a sheet shape from polyethylene terephthalate, the leader member 13 is strong and returns to the state of protruding in the tangential direction of the recording paper 12. Further, since the leader member 13, the leading end portion 12a of the recording paper 12, and the outer periphery of the recording paper roll 10 are adhered by the adhesive 14,
The recording paper roll 10 is not loosened.

Then, as shown in FIG. 6, the loading cover 22 of the color thermal printer 18 is opened, and the recording paper roll 10 is loaded in the paper feeding section 21. At this time, since the leader member 13 is displaced from the center in the width direction of the recording paper 12 to the side end side and is colored in a color different from that of the recording paper 12, it is determined whether the loading direction of the recording paper roll 10 is correct. Can be determined. When the recording paper roll 10 is set in the paper feed unit 21, the leading end of the leader member 13 rides on the lower pull-out roller 25. When the loading lid 22 is closed as shown in FIG.
Nips the leading end of the leader member 13.

When the loading lid 22 is closed, a precut process is executed by a signal from the lid detection sensor. In this pre-cut processing, the lower draw roller 25 and the capstan roller 30 rotate, and the leader member 13 is conveyed toward the recording paper entrance 38. At this time, the leader member 1
3 and the outer periphery of the recording paper roll 10 are gradually peeled off. Further, since the leading end portion of the non-adhesive portion 13b is cut into a tapered triangle, the non-adhered portion 13b passes through the transport roller pair 29 smoothly. When the lead member 13 and the leading end of the recording paper roll 10 pass through the cutter 37, the cutter 37 operates and the leading end 1 of the recording paper 12 together with the leader member 13.
Precut 2a. The pre-cut portion is discharged from the recording paper entrance 38. Then, after the pre-cut, the leading end 12a of the recording paper 12 is returned to the transport roller pair 29.

When printing is designated, the transport roller pair 2
9 rotates and transports the recording paper 12 toward the recording paper entrance 38. During this conveyance, the thermal head 33 moves the recording paper 1
Heating is performed while pressing the layer 2 to form a yellow thermosensitive coloring layer, and a yellow image is recorded line by line. The portion where the yellow image is recorded is the yellow UV lamp 35.
Is fixed by ultraviolet rays from After the recording and fixing of the yellow image, the recording paper 12 is returned, and the recording and fixing of the magenta image are performed during the next conveyance. Further, after recording the magenta image, the recording paper 12 is returned, and a cyan image is recorded. Finally, the recording paper is cut by the cutter 37 and discharged from the recording paper entrance 38.

In the above embodiment, a leader member separate from the recording paper was used. For example, as shown in FIGS. 7 and 8, both sides of the leading end 12a of the recording paper 12 are cut obliquely to form a triangle. Alternatively, the leading end folded portion 42 that is folded inward and double folded may be used as a leader. In this case, the adhesive 14 is provided on the innermost surface of the outer periphery of the recording paper roll 43 in the vicinity of the leading edge folded portion 42, and the recording paper roll 43 is adhered to the inner outer surface, thereby preventing the recording paper roll 43 from loosening. Since the leading edge folded portion 42 as a leader is double folded, the rigidity is increased, and the leading edge folded portion 42 travels on the transport path without jamming during sheet feeding. Further, the adhesive portion is peeled off during paper feeding, and the recording paper 12 is drawn into the transport path.

When the double-folded front-end folded portion 42 is provided, the stiffness becomes too strong, and the front-end folded portion 42 may not be properly nipped by the pair of pull-out rollers 24 and 25. For example, as shown in FIG. 9 and FIG. 10, it is preferable to provide a U-shaped notch 44 around the adhesive portion by the adhesive 14. As a result, the stiffness does not become unnecessarily strong, so that the leading end folded portion 42 smoothly passes between the pair of pull-out rollers 24 and 25.

The example shown in FIG.
2a is cut into a triangle, and two oblique sides of the triangle are bent inward to make the side end folded portion 45 having a strong waist as a leader. Also in this case, the adhesive 14 is provided on the innermost surface of the outermost periphery of the recording paper roll 46, and the recording paper roll 46 is prevented from loosening by making the inner surface adhere to the adhesive. In order to facilitate the nip between the pair of pull-out rollers 24 and 25, it is preferable to deeply fold the two oblique sides.

In the example shown in FIG. 12, a central folded portion 47 reinforced by mountain folding along the longitudinal direction of the recording paper 12 at the center in the width direction of the triangular tip portion 12a is used as a leader. In the example shown in FIG. 13, the center folded portion 48 reinforced by valley folding is used as a leader. In either case, the adhesive 14 is provided at the center of the recording paper 12 in the width direction near the center folded portions 47 and 48 to prevent the recording paper rolls 49 and 50 from becoming loose.

FIG. 14 shows a color thermal printer in which a recording paper roll is axially loaded from the side. The color thermal printer 53 includes a printer main body 54 and a loading lid 55. The loading lid 55 is provided on a side surface of the printer main body 54, and opens and closes a paper feed unit 56 of the printer main body 54. The printer body 54 is provided with a lock button 57, and when the loading lid 55 is closed, the locking member 5
7a is locked in the locking hole 55a of the loading lid 55,

The recording paper roll 4 is attached to the printer body 54.
3 and a sensor for detecting that the loading lid 55 is closed. When the loading of the recording paper roll 43 and the closing of the loading lid 55 are detected, at least one of the pair of pull-out rollers 64 and 65 shifts to nip the leading end folded portion 42. When the pair of drawing rollers 64 and 65 rotate, the adhesive portion between the recording paper 12 and the outer periphery of the recording paper roll 43 is peeled off, and the recording paper 12 is sent out to the transport path. Thereafter, the leading edge folded portion 42 is precut from the recording paper 12, and
After this pre-cut, printing of the recording paper 12 is performed as described above.

In the above embodiment, the leader member 13 is made of polyethylene terephthalate. However, a material having elasticity, that is, flexibility and strong stiffness can be used. In the above embodiment, the adhesive 14 is used to fix the leading end 12a of the recording paper 12 and the outer circumference of the recording paper rolls 10, 43, 46, 49, 50. May be used. Further, for example, a cleaning unit in which an abrasive is layered may be provided in the reader of the above embodiment, and the thermal heads 33 and 58 may be cleaned for each set of the recording paper roll.
