Description of the Related Art Conventionally, a configuration is known in which the outside of a stacked sheet is covered with a package material, and the sheet is opened and used when used in a printer. In this configuration, a plurality of sheets of paper can be handled collectively in a package unit, so that the usability is improved. In addition, since the inner sheets can be covered and protected, heat-sensitive paper which is particularly sensitive to light and heat is adopted as the sheets. Useful in cases.
In this paper package, a part of the package material is exposed by cutting or folding a part of the package material at the time of opening, and is set in a printer together with the package material in this state.
[0003]
[Problems to be solved by the invention]
However, the paper package of the prior art is compatible with a relatively large-sized (corresponding to a paper size of B5 size or more) printers, and is constituted by a simple cardboard box. With the spread of personal digital assistants (PDAs), the demand for printers, which are small and handy, has been increasing.
Then, in order to improve the handling of small-sized paper used in this type of small-sized printer, a package material for accommodating the paper is formed by a sheet-like member (for example, a cardboard material), and assembled into a box shape. It is conceivable to use a paper package having the above configuration.
In this type of paper package for a small printer, the sheet-like member is formed in advance in a shape having protrusions and cuts, and when assembling it into a box, the protrusions are simply inserted into the cuts. The fixing is advantageous in cost as compared with the case where an adhesive or an adhesive tape is used.

BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the invention will be described.
[0011]
[Printer configuration]
First, a schematic structure of a printer 1 as a thermal recording device will be described with reference to FIGS.
FIG. 1 is a perspective view of the printer, and FIG. 2 is a side sectional view. FIG. 3 is a side cross-sectional view showing a state where a sheet is set in the sheet storage unit. FIG. 4 is an enlarged cross-sectional view showing details of the sheet separating unit and the printing mechanism unit.
[0012]
As shown in FIG. 1, the printer 1 has a rectangular configuration (a size capable of accommodating paper of about A6 to A7 size) in plan view, and has a compact configuration having a thickness of about 2 cm or less. ing.
The main body case 2 of the printer 1 is formed by covering the lower surface of the frame 3 with the lower cover 4 and partially covering the upper surface with the upper cover 5.
[0013]
In the remaining portion of the upper surface of the frame body 3 except for the portion covered by the upper cover 5, a paper storage portion (paper feed portion) 6 is formed as shown in FIG. In the paper storage unit 6, a paper package 9 in which a plurality of A6-A7 size cut sheet-shaped thermal papers (medium to be printed; hereinafter, referred to as "paper") 7 are stored in a package material 8 is shown in FIG. As shown in the figure.
The upper part of the paper storage unit 6 is covered with a lid 10, and the lid 10 is rotatable as shown in FIG. A lock mechanism (not shown) is provided on the main body case 2 side. With the paper package 9 set in the paper storage section 6 as described above, the lid 10 can be closed and locked as shown in FIG. Has become.
[0014]
At one end of the sheet storage unit 6, a pickup roller 12 as a sheet separation unit 11, a separation block 13, and the like are arranged. Further, below the upper cover 5, a thermal head 15, a platen roller 16, and a paper guide 17 as a printing mechanism unit 14, which will be described in detail later, are arranged.
[0015]
The paper separating unit 11 will be described.
As shown in FIG. 4, a pickup roller 12 and a separation block 13 are provided at an end of the paper storage unit 6 near the printing mechanism unit 14. A pressing plate (pickup pressing means) 18 is rotatably supported on the inner surface of the lid 10 facing the paper storage unit 6 side.
An urging spring 19 is interposed between the pressing plate 18 and the lid 10, and constantly applies an urging force to the pressing plate 18 in a direction for rotating the pressing plate 18 downward.
[0016]
The paper package 9 is a state in which the lower surface of the lowermost paper 7 among the papers 7 housed inside in a stacked state with the printing surface facing downward is partially exposed from the package material 8. Is set in the sheet storage unit 6. When the lid 10 is closed and locked, the pressing plate 18 urged downward by the above-described urging spring 19 moves the area on the leading side of the sheet 7 in the sheet conveying direction through the package material 8. Press. As a result, the exposed portion of the sheet 7 comes into contact with the pickup roller 12 and is pressed by an appropriate force.
[0017]
A separation block 13 is provided close to the pickup roller 12, and the separation block 13 includes a separation guide surface 13a inclined with respect to the sheet feeding direction of the pickup roller 12.
[0018]
When the pickup roller 12 is rotationally driven in this configuration, a conveying force is applied to the lowermost sheet 7 that comes into contact with the pickup roller 12. Then, in combination with the separation action of the separation guide surface 13a of the separation block 13, only one sheet 7 located at the lowermost layer is separated and sent out.
[0019]
The printing mechanism 14 will be described.
A platen roller 16 is rotatably provided adjacent to the separation block 13, and a paper guide 17 is arranged near the outer peripheral surface thereof.
As shown in the enlarged view of FIG. 4, the paper guide 17 has a concavely curved sliding contact surface 17 a along the outer peripheral surface of the platen roller 16. A pressing coil spring 20 is provided between the paper guide 17 and the main body case 2, and urges the sliding contact surface 17 a toward the outer peripheral surface of the platen roller 16.
[0020]
In this configuration, the sheet 7 separated by the above-described sheet separation unit 11 is conveyed by the pickup roller 12 and is disposed between the lower end of the separation block 13 and the guide plate 21 for directing the sheet to the platen roller 16 side. Pass through.
The sheet 7 is guided by the guide plate 21, and is sent from the lower surface of the platen roller 16 to between the platen roller 16 and the paper guide 17. The paper 7 is conveyed while being held between the outer peripheral surface of the platen roller 16 and the sliding contact surface 17a of the paper guide 17 while being inverted in a horizontal "U" shape by the rotation of the platen roller 16, and the printing surface Of the platen roller 16 while facing upward.
[0021]
The thermal head 15 located on the upper surface side of the platen roller 16 has a heating element 15a. The thermal head 15 is provided so as to be rotatable around a rotation shaft 15 b, and the heating element portion 15 a can be brought into contact with and separated from the upper surface of the platen roller 16.
The reason why the thermal head 15 is configured to be rotatable in this way is that the thermal head 15 does not hinder the work in the jam paper removal operation when the paper 7 is jammed between the platen roller 16 and the paper guide 17. This is to avoid becoming
One end of a torsion coil spring type spring 22 is locked to the thermal head 15, and the heating element 15 a of the thermal head 15 constantly applies a biasing force in a direction approaching the upper surface of the platen roller 16.
With this configuration, as described above, the heating element 15a of the thermal head 15 contacts the upper surface of the sheet sent by the platen roller 16 with the printing surface facing upward, and printing is performed on the sheet 7 at the contacting point. You.
[0022]
The thermal head 15 is of a line head type, and can print arbitrary characters and images on the heat-sensitive paper 7 that is being conveyed for each line extending in a direction perpendicular to the conveyance direction of the paper 7. The printing width when printing per line is set substantially equal to the width of the paper 7 to be printed.
The use of the thermal head 15 as a print head in this manner can eliminate the need for consumables such as ink and an ink ribbon by using thermal paper as a printing medium, and can omit a mechanism for supplying ink. This is because the printer 1 can be made compact.
In the present embodiment, a so-called thermosensitive coloring type in which a coloring layer that develops color by heating the thermal head 15 is formed as an image receiving layer on one surface thereof is used as the thermal paper. However, the present invention is not limited to this, and for example, a perforated layer perforated by heating may be laminated on a substrate layer to form an image receiving layer (thermosensitive perforated type). Further, it is possible to use not only the thermal paper but also a thermal transfer system or other paper.
[0023]
The separation block 13 has a paper discharge guide surface 13b that is inclined with respect to the paper feeding direction of the platen roller 16.
In this configuration, the sheet 7 on which printing has been performed by the heating element portion 15a of the thermal head 15 is guided by the discharge guide surface 13b, and as shown by a chain line in FIG. The paper is discharged to the upper side of the lid 10 through a gap formed between the lid 10 and the lid 10.
[0024]
[Structure of paper package]
Next, the paper package 9 set in the printer 1 in the present embodiment will be described.
FIG. 5 is a perspective view of the paper package, and FIG. 6 is a developed view of the package material. The steps of manufacturing the paper package are shown in order in FIGS.
[0025]
As shown in FIG. 5, the paper package 9 is formed by stacking a plurality of (for example, about 50) small-sized thermal sheets in the form of cut sheets having a size of, for example, about A6 to A7 inside the package material 8. Configuration. The user purchases a paper package sold in the state shown in FIG. 5, exposes the internal paper by performing a process described below, and sets the package together with the package material 8 in the paper storage unit 6 of the printer 1. Have been.
[0026]
The package material 8 is formed by folding a flat cardboard material (sheet-like member) into a box shape. FIG. 6 shows a state before the cardboard material is bent. The cardboard material has a first exterior part 41, a second exterior part 42, around a bottom 40 having substantially the same shape (rectangle) as the paper 7. The tongue 43 and the lid 44 are formed integrally with each other. In FIG. 6, a thin dashed line indicates a portion on which the fold processing is performed, and the cardboard material is easily folded at the fold for convenience in assembling.
A cutout 31 for printer setting is formed on the bottom 40, a cutout 32 for fixing the lid and a cutout 33 for fixing the tongue on the tongue 43, and a cutout 34 for fixing the exterior is formed on the first exterior portion 41, respectively. Some parts can be inserted. Details will be described later.
[0027]
[Manufacturing process of paper package]
First, a process of manufacturing the paper package 9 will be described below.
The cardboard material in the state of FIG. 6 is first folded 180 ° so that the tongue 43 is located above the bottom 40 as shown in FIG. Next, as shown in FIG. 8, the first exterior part 41 is bent so as to overlap on the tongue part 43, and the insertion part 39 provided at the tip thereof is attached to the tongue part 43 formed on the tongue part 43. It is inserted into the fixing notch 33. Further, as shown in FIG. 9, the second exterior part 42 is bent so as to overlap the first exterior part 41, and the insertion part 35 provided at the tip thereof is provided on the first exterior part 41. Into the cutout 34 for fixing the exterior.
As a result, a box as shown in FIG. 10 is formed. As shown in FIG. 10, this box is formed in a rectangular shape, and one side in the longitudinal direction is open.
[0028]
Then, as shown in FIG. 10, the stacked sheets 7 are inserted from the open side of the box so as to be inserted between the bottom 40 and the tongue 43 of the cardboard material.
When the paper 7 is inserted, its orientation is determined in advance so that the heat-sensitive surface (printing surface) of the paper 7 faces the bottom 40 side. This is because the paper package 9 is later set in the printer, and when the paper 7 is sent to the printing mechanism unit 14 of the printer, the heat-sensitive surface of the paper 7 faces the thermal head 15 side.
[0029]
After the paper 7 is inserted, as shown in FIG. 11, the lid 44 is folded upward, and the projection 38 at the tip is inserted into the lid fixing notch 32 formed on the tongue 43. As a result, the box body is fixed in a state where the open side is covered with the lid portion 44.
[0030]
Thus, the paper package 9 shown in FIG. 5 is completed. In the present embodiment, the above-described paper package 9 manufacturing operation is performed by the manufacturer, and the user using the printer 1 is sold in the state shown in FIG. The purchased paper package 9 is purchased, the paper package 9 is subjected to simple operations described below, and then set on the printer 1 for use.
[0031]
[Setting work of paper package on printer]
Next, an operation flow for setting the paper package 9 in the state of FIG. 5 in the printer will be described with reference to FIG. 12 to 16 show the state of the work in order.
[0032]
First, the user pulls out the projection 38 of the lid 44 of the paper package 9 in the state of FIG. 5 from the lid fixing notch 32 and opens the lid 44 as shown in FIG.
Then, as shown in FIG. 13, a finger is put on the cutout portion 45 formed on each of the first exterior portion 41 and the second exterior portion 42, and the cutout portion 45 is cut off. As shown in FIG. 6, the two cutout portions 45 are formed in portions of the package material 8 extending from the exterior portion (41 or 42) to the bottom portion 40. The package material 8 is perforated 46 along the contour of the cutout 45 in order to facilitate the work of separating the cutout 45.
[0033]
By the work of separating the cutout portion 45, a part of the bottom portion 40 can be folded back together with the lid portion 44 at a fold indicated by a symbol A in FIG.
After the user has folded the lid 44 and the bottom 40 in this manner (FIG. 14), the protrusion 38 formed at the tip thereof is connected to the printer set formed on the bottom 40 of the package material 8 as shown in FIG. (FIG. 15).
As described above, the cover 44 is fixed in an open state, and a part of the sheet 7 inside is exposed from the package material 8.
[0034]
Next, as shown in FIG. 16, the paper package 9 in this state is set in the paper storage unit 6 of the printer 1. As a result, a portion of the lowermost layer of the sheets 7 stacked in the package material 8 and exposed from the package material 8 contacts the upper surface of the pickup roller 12. Therefore, by rotating the pickup roller 12 in this state, the sheet 7 can be fed out and conveyed.
[0035]
3 and 4 show a state in which the lid 10 is closed. In this case, the tongue 43 is provided between the pressing plate 18 for pressing the sheet 7 against the pickup roller 12 and the sheet 7. To position.
[0036]
In this way, the paper 7 is set in the printer 1 in the form of a paper package 9, and when the paper 7 is fed out one by one and runs out, the remaining package material 8 is taken out of the printer 1 and discarded. Become.
This configuration is useful in that even if a large number of sheets are printed by the printer 1, the sheet separation performance of the pickup roller 12 and the separation block 13 does not decrease. That is, if the paper 7 is directly in contact with the pressing plate 18 without the intermediary of the tongue 43, the pressing plate 18 is worn due to the continuous use of the printer 1, the frictional force between the pressing plate 18 and the paper 7 is reduced, and the paper 7 is separated. The effect is reduced, and a phenomenon (multi-feeding) in which a plurality of sheets of paper 7 are simultaneously fed tends to occur. In this regard, in the configuration of the present embodiment, the tongue 43 is in direct contact with the paper 7, and the tongue 43 is replaced with a new one together with the package material 8 every time a predetermined number of papers 7 are used up. However, the frictional force between the tongue 43 and the sheet 7 does not decrease due to long-term use, and a good separating action is always performed, thereby preventing a sheet conveyance trouble such as a double feed.
[0037]
[Work when replacing the paper package]
Depending on the purpose, the printer 1 may be, in addition to a simple thermal paper, a copy paper in which two sheets are glued to enable simultaneous printing by the printer 1 or an adhesive layer on the back of the thermal paper. It can be printed on various types of paper, such as label paper, which can be formed and bonded to a separator, peeled off from the separator after printing, and pasted.
Therefore, there is a case where the user wants to replace the paper 7 of the paper package 9 with another type of paper before the paper 7 is completely used up. In the present embodiment, since only one type of paper is stored in one package material 8, it is necessary to replace the entire paper package 9 when it is desired to replace it with a different paper 7.
[0038]
In such a case, the user opens the cover 10 of the printer 1 and removes the paper package 9 from the paper storage unit 6. Thereafter, as shown in FIG. 17, the protrusion 38 at the tip of the lid portion 44 folded back to the lower side of the bottom portion 40 is pulled out from the notch 31 for printer setting, and as shown by arrows in FIGS. Is folded upward. Then, by inserting the projection 38 into the lid fixing notch 32, as shown in FIG. 18, the lid part 44 is fixed in a closed state (a state in which the open side of the package material 8 is closed again).
The sheet 7 is stored in the state of FIG. 18, but when it is used again, the projection 38 at the tip of the lid 44 is pulled out from the notch 32 for fixing the lid, and the lid 44 is moved downward in the reverse of the above-mentioned operation. When the projection 38 is turned back and inserted into the notch 31 for printer setting, the projection 38 can be set in the printer 1.
[0039]
[Configuration of notch for printer set]
Next, the configuration of the printer setting cut 31 will be described.
FIG. 19 is an enlarged perspective view of the paper package 9 with the bottom side facing upward. As shown in FIG. 19, the printer setting cut 31 is composed of a first cut 31a whose main part is formed in a gentle arc, and a straight cut 31a connected to the center of the first cut 31a at a right angle. And a second notch 31b, and is formed in a substantially "T" shape or a "Y" shape. Both the first cut 31a and the second cut 31b are provided so as to penetrate in the thickness direction of the package material 8.
The first cut 31a is a main part of the printer setting cut 31, and is provided in a direction substantially perpendicular to the insertion direction of the projection 38 (indicated by a white arrow in FIG. 19). When the paper package 9 is set in the printer 1, a part of the paper 7 is exposed from the package material 8 by inserting the projection 38 of the lid portion 44 folded as described above into the first cut 31 a. It can be fixed in the state where it was done.
[0040]
The first cut 31a is a cut having no width, and a portion B1 located on the back side of the projection 38 in the insertion direction with respect to the first cut 31a, and the front side of the protrusion 38 in the insertion direction with respect to the cut 31a. Is in contact with the portion B2 located at the notch 31a.
Therefore, in a state in which the protrusion 38 is not inserted (that is, a state in FIG. 5 in which the paper package 9 is a new unopened article, or a state in FIG. 18 in which the paper package 9 is stored after being used halfway). Since the first cut 31a portion is closed tightly, it is excellent in light-shielding properties, so that light does not enter the inside from the first cut 31a.
Particularly, in the present embodiment, since the first cut 31a is provided at a portion (that is, the bottom portion 40) that covers the heat-sensitive surface of the paper 7 that is a thermal paper, the first cut 31a is closed tightly. Thus, the heat-sensitive surface of the heat-sensitive paper is prevented from being deteriorated by being exposed to light, and the heat-sensitive surface can be surely protected.
[0041]
The second notch 31b is provided so as to equally divide a portion B2 of the bottom portion 40 of the package material 8 closer to the insertion direction of the protrusion 38 than the first notch 31a in the insertion direction. I have. As a result, the first cut 31a is easily spread, and the work of inserting the projection 38 into the first cut 31a (that is, the cut 31 for the printer set) is facilitated.
[0042]
This effect will be specifically described with reference to FIG. FIG. 20A is a perspective view and a cross-sectional view showing a state in which the projection 38 of the lid portion 44 is to be inserted with the bottom side facing upward. In the state described above, the user slides the protrusion 38 on the bottom 40 while slightly pressing the portion B2 on the near side in the protrusion insertion direction of the first cut 31a with the protrusion 38 so as to slide the protrusion 38 on the first cut 31a. Approaching 31a.
Then, as shown in FIG. 20 (b), the portion B2 that is divided by the above-described second cut 31b and that is closer to the protrusion insertion direction than the first cut 31a is separated by the second cut 31b. It falls down like a crack and easily separates from the part B1 on the back side in the projection insertion direction. This means that the first cut portion 31a can be easily spread, and the protrusion 38 can be easily inserted between the two portions B1 and B2 which are separated from each other.
[0043]
As a comparative example, FIG. 21 shows a case where the projection 38 is inserted in a configuration in which only the first cut 31a is provided and the second cut 31b is not provided.
Since the portions B1 and B2 sandwiching the first cut 31a are in contact with each other as described above, as shown in FIG. Even if it is pushed, the portion B1 on the far side in the projection insertion direction may be lowered accordingly. In this case, the projection 38 cannot be inserted unless the first notch 31a is tightly closed and the first notch 31a is pryed open at the tip of the projection 38.
This phenomenon is particularly likely to occur when an unused paper package 9 is opened and used for the first time. That is, the paper package 9 in the unused state is generally filled with the paper 7 stacked to the full capacity, and in this state, the gap d between the bottom 40 of the paper package 9 and the paper 7 is small. Normal. This means that when pushing the portion B2 on the front side in the protrusion insertion direction below the first cut 31a in order to insert the protrusion 38, the pressing stroke cannot be made too large. Therefore, as described above, a phenomenon that the first cut 31a does not easily spread while the first cut 31a is closed frequently occurs.
[0044]
In this regard, according to the present embodiment having the second cuts 31b as shown in FIG. 20, even when the stroke of pressing the portion B2 on the near side in the projection insertion direction is small, the portion of the first cut 31a is easily widened. Therefore, the projection 38 can be easily and smoothly inserted.
[0045]
When the projection 38 is inserted into the first cut 31a, as shown in FIG. 16, a portion B1 on the back side in the projection insertion direction from the first cut 31a comes into contact with the projection 38 in a planar manner, and 38 plays a role of generating a frictional force that keeps it from accidentally coming off.
Therefore, in the portion B1 on the back side in the projection insertion direction, no cut is provided to divide the portion B1. As a result, the rigidity of the portion B1 on the back side in the projection insertion direction is improved, so that the portion B1 is not easily bent, and the friction holding force for holding the projection 38 so as not to come off is secured. The reason why the first cut 31a is formed in the shape of an arc whose central portion bulges toward the near side in the projection insertion direction is that the area of the portion B1 on the back side in the projection insertion direction is increased, This is to increase the holding area by increasing the contact area with the contact.
[0046]
In the present embodiment, the second cut 31b is provided at a position that bisects the above-described portion B2 on the near side in the protrusion insertion direction, in a direction parallel to the protrusion insertion direction. However, the present invention is not limited to this, and various variations in the position, direction, and shape are conceivable.
Further, in the present embodiment, only one second cut 31b is provided, but the present invention is not limited to this. For example, two cuts may be provided, and B1 may be divided into three parts.
[0047]
As shown in FIG. 6, the package material 8 of the present embodiment has not only the notch 31 for the printer set provided on the bottom portion 40, but also the notch 33 for the tongue fixing and the notch 34 for the exterior fixing. The insertion portion (39/35) is provided at the center of the first cut capable of being inserted so as to divide the projection (39/35) of the first cut into a portion on the near side in the insertion direction. It has a shape provided by connecting the second cuts. This facilitates the insertion work of the insertion portions 39 and 35 when assembling the package material 8 into a box shape.
[0048]
From the viewpoint of securing the light shielding property and protecting the thermal paper inside, the notch 31 for the printer set of the present embodiment has the first notch 31a as a notch having a small width, and the back side of the notch 31a in the projection insertion direction. The configuration is such that the portion B1 and the portion B2 on the near side are in contact at the first cut 31a.
However, the technical scope of the present invention is not limited to this, and the first cut 31a may have a shape having an appropriate width (for example, a shape such as the above-described lid fixing cut 32 shown in FIG. 6 and the like). By providing the second cuts 31b as described above, the effect that the first cuts 31a are easily spread can be sufficiently achieved.
Similarly, in the present embodiment, the second cut 31b is also a cut having no width, and the portion B2 on the near side in the protrusion insertion direction is the cut 31b divided by the second cut 31b. The parts are in contact with each other to ensure light-shielding properties. However, the present invention is not limited to this configuration, and the second cut 31b may be configured to have an appropriate width.
[0049]
The notch 31 for printer setting provided in the bottom portion 40 of the package material 8 corresponds to a portion where the bottom portion 40 covers the heat-sensitive surface of the heat-sensitive paper (paper 7). Since there may be a situation where the projection 38 is not inserted into the cut 31 for a long time at the time of storage or the like, there is a situation that a light shielding property is strongly required so that light does not enter from the cut 31. On the other hand, the notch 33 for fixing the tongue and the notch 34 for fixing the exterior are not provided in a portion covering the heat-sensitive surface, and once the package material 8 is assembled in a box shape, it is normally used. As long as the insertion portions 39 and 35 are not pulled out from the cuts 33 and 34, the first and second cuts may be formed to have an appropriate width.

Although the paper package 9 of this embodiment is of a type in which thermal paper is stored, the technical scope of the present invention is not limited to this. For example, the present invention is similarly applicable to a paper package of a type that stores copy paper and label paper as described above.

【The invention's effect】
The present invention is configured as described above, and has the following effects.
[0052]
That is, as described in claim 1, there is provided a sheet as a printing medium of the printer, and a package material which is formed in a box shape by folding a sheet member and covers the outside of the stacked sheets. A paper package configured to be set in the printer together with the package material in a state where a part of the paper is exposed from the package material, wherein a linear first cut is formed in the package material. A portion provided on the package material so that the projection provided on the package material can be inserted into the first cut, and a portion of the package material located closer to the insertion direction of the protrusion than the first cut. Since a second cut connecting to the first cut is formed so as to divide
Since the second cut is provided at a portion closer to the projection insertion direction than the first cut, the first cut is easily spread. Therefore, the work of inserting the protrusion into the first cut becomes easy.
[0053]
As shown in claim 2, a portion of the package material located on the back side in the protrusion insertion direction with respect to the first cut, and a portion located on the near side with respect to the protrusion insertion direction with respect to the first cut. Are configured to contact each other at the first cut portion,
The projection can be easily inserted. That is, in general, in a configuration in which the back side and the front side of the first cut are in contact with each other (the first cut portion is exactly closed), the back side part also moves with the movement of the front side, It is very difficult to open the first cut, and it is difficult to insert the projection. However, in the present configuration, the front side is easily separated from the back side by the presence of the second cut, so that the first cut is easily opened as shown in the effect of claim 1. Easy insertion.
[0054]
As described in claim 3, the paper is a thermal paper, and the first cut and the second cut are formed in a portion of the package material covering a heat-sensitive surface of the thermal paper.
Since the first cut portion of the package material is closed tightly, it is excellent in light-shielding properties and prevents the heat-sensitive surface of the heat-sensitive paper from being deteriorated due to exposure to light.
[0055]
As shown in claim 4, in the portion of the package material located on the near side in the protrusion insertion direction with respect to the cut, the portions divided by the second cut are in contact with each other at the second cut. It is configured as
Since the second cut portion is also tightly closed, the light-shielding property is further improved, and the heat-sensitive surface of the heat-sensitive paper is prevented from being deteriorated by being exposed to light.
