Description

TECHNICAL FIELD The present invention relates to a roll-shaped thermal transfer image-receiving sheet body used in a thermal transfer printer and a combination of the roll-shaped thermal transfer image-receiving sheet body and a thermal transfer sheet.

Conventionally, a thermal transfer sheet having a colored transfer layer formed on a substrate is used to heat the back side of the colored transfer layer to a character, a figure, or a pattern to thermally transfer the above-mentioned colored transfer layer onto the surface of a transfer target. There is known a thermal transfer method for forming an image. The thermal transfer method is roughly classified into two methods, a thermal fusion transfer type and a sublimation transfer type, depending on the constitution of the colored transfer layer.

The thermal melting transfer type uses a thermal transfer sheet that contains a coloring material on a base material and is easily softened and melted by heating to form a colored transfer layer that can be transferred. The colored transfer layer is transferred onto the surface of the body. On the other hand, the sublimation transfer type uses a thermal transfer sheet in which a color material (dye) that sublimates or migrates by heat is carried on a substrate as a colored transfer layer by a suitable binder, and the color is transferred by heating from the back side. The dye in the layer is thermally transferred to the receiving layer provided on the surface of the transferred material.

Both systems are capable of forming mono-color and multi-color images, and in the case of multi-color images, for example, yellow, magenta, cyan, and, if necessary, black three-color or four-color coloring transfer layers. Furthermore, a multicolor color image can be formed by preparing a thermal transfer sheet provided with a transparent protective layer and the like and thermally transferring each color onto the surface of the same transfer target.

In such a thermal transfer method, the thermal transfer sheet to be used has an elongated shape, and is stretched between a supply side bobbin and a winding side bobbin, which are a pair of thermal transfer sheet bobbins, and a supply side bobbin in the thermal transfer printer. Is sent to the winding side bobbin side, and thermal transfer recording is performed on the transfer target. Further, the thermal transfer image-receiving sheet that is the transferred material is generally in the form of a roll wound around a hollow cylindrical paper tube, and by rotating both end surfaces while being supported by receiving flanges, The thermal transfer image receiving sheet is sequentially fed out and thermal transfer recording is performed.

In the thermal transfer method as described above, since the usage amount (length) of the thermal transfer image receiving sheet is uniquely determined with respect to the usage amount (length) of the thermal transfer sheet, for example, one roll of the thermal transfer sheet wound on the supply side bobbin is used. One roll-shaped thermal transfer image receiving sheet wound in a predetermined length corresponding to the length is associated with each other, and one corresponding one roll of the thermal transfer sheet and the roll-shaped thermal transfer image receiving sheet is set, or this It is preferable to add a winding-side bobbin to and to send it to a customer who uses the thermal transfer printer. By doing so, it is possible to avoid a situation in which the customer side receives either the thermal transfer sheet or the thermal transfer image receiving sheet more than necessary and becomes an excess inventory.

By the way, both the thermal transfer sheet and the thermal transfer image receiving sheet need to be properly protected during packaging in order to avoid the influence of external force during transportation as much as possible.However, the thermal transfer sheet made of a flexible and thin material is not damaged. In particular, sufficient protection is required because it is likely that the quality will be affected by the above. When a scratch or pressure is applied to the thermal transfer sheet, the ink in that portion may not be properly transferred to the thermal transfer image receiving sheet, which may cause quality defects such as color loss.

Patent Document 1 describes a package in which a replacement ink ribbon, which is a thermal transfer sheet, including a supply side bobbin and a winding side bobbin is fixed by a holding member so as to be separated from each other.

JP, 2002-29112, A

1. First Embodiment A first embodiment of the roll-shaped thermal transfer image receiving sheet body of the present disclosure will be described. FIG. 1 is a perspective view showing a roll-shaped thermal transfer image-receiving sheet body 1 and a thermal transfer sheet bobbin combination body 10 according to the first embodiment. FIG. 2 is a side view of the roll-shaped thermal transfer image-receiving sheet body 1 of FIG. 1 viewed from the end face side and a cross-sectional view taken along a predetermined plane parallel to the axial direction. FIG. 3 is a sectional view showing a state where a paper flange is fitted into the roll-shaped thermal transfer image receiving sheet 1. Further, FIG. 4 is a side view and a cross-sectional view corresponding to FIG. 2 of the combination 11 of the roll-shaped thermal transfer image receiving sheet body and the thermal transfer sheet. The configuration of each unit will be described below.

(A) Rolled thermal transfer image receiving sheet body As shown in FIG. 1, the rolled thermal transfer image receiving sheet body 1 has a substantially cylindrical outer shape in which a thermal transfer image receiving sheet 2 is continuously wound around a paper tube 3. .. The thermal transfer image-receiving sheet 2 has a primer layer and a receiving layer laminated in this order on a base material, and the thermal head of the printer transfers the coloring material of each color of the thermal transfer sheet to the receiving layer of the thermal transfer image-receiving sheet 2. A color image or the like can be formed by thermal transfer by heat. The paper tube 3 has a hollow cylindrical shape having a through hole having an inner diameter of 2 inches or 3 inches, and is made of paper material such as compressed cardboard or various plastic materials. However, in order to reduce the amount of dust generated after the thermal transfer image receiving sheet 2 is used, a coreless type in which only the thermal transfer image receiving sheet 2 is directly wound without using a paper tube may be used.

Here, for convenience of explanation, xyz coordinates are set. The axial direction of the substantially cylindrical shape of the roll-shaped thermal transfer image receiving sheet 1 is the y direction, and the vertical direction when viewed from the y direction side is perpendicular to the y direction and the end face of the roll thermal transfer image receiving sheet 1 is the z direction. , The horizontal direction perpendicular to the y and z directions is the x direction.

(B) Holding Tool In the roll-shaped thermal transfer image receiving sheet body 1 in which the thermal transfer image receiving sheet 2 is wound around the paper tube 3, the holding tool 6 is arranged in the region on the core side where the thermal transfer image receiving sheet 2 is not wound. There is. The roll core of the roll-shaped thermal transfer image receiving sheet 1 usually means the paper tube 3, but the roll core side on which the heat transfer image receiving sheet 2 is not wound is the thermal transfer image receiving member inside the roll thermal transfer image receiving sheet 1. It refers to a substantially cylindrical hollow region in which the sheet 2 is not formed, and this also includes the paper tube 3.

The hollow portion of the through hole of the paper tube 3 included on the core side where the thermal transfer image receiving sheet 2 is not wound has an outer diameter substantially the same as the inner diameter of the paper tube 3, and like the paper tube 3. A holder 6 extending in the axial direction is fitted. The holder 6 has a hole 5 of a predetermined shape inside and is constituted by an elastic cushioning member 4 having a substantially cylindrical outer shape. The hole 5 having a predetermined shape is continuously provided as a through hole along the y direction which is the axial direction of the substantially cylindrical shape of the cushioning material 4, and when viewed in a cross section taken along the xz plane perpendicular to the y direction. In addition, the holes having the same shape are always formed.

Further, the cushioning material 4 constituting the holder 6 has a length along the y direction shorter than the lengths of the paper tube 3 and the thermal transfer image-receiving sheet 2, and both end faces of the cushioning material 4 have the paper tube 3 and the thermal transfer material. When viewed in the y direction from both end faces of the image receiving sheet 2, the image receiving sheet 2 is arranged closer to the center on the axial line of the substantially cylindrical shape formed by the cushioning material 4, the paper tube 3 or the thermal transfer image receiving sheet 2. Therefore, as shown in FIG. 1, the cushioning material 4 forming the holder 6 does not exist inside the paper tube 3 near both end surfaces of the thermal transfer image receiving sheet 2.

However, the structure of the holder 6 is not limited to the above, and for example, both end surfaces of the cushioning material 4 constituting the holder 6 are substantially the same as both end surfaces of the paper tube 3 and the thermal transfer image receiving sheet 2 along the y direction. It may be formed at the position. Further, the axial direction of the substantially cylindrical shape formed by the outer shape of the cushioning material 4 does not have to be along the y direction, which is the axial direction of the substantially cylindrical shape formed by the paper tube 3 and the thermal transfer image-receiving sheet 2, and is in the y direction. A substantially cylindrical shape of the cushioning material 4 may be formed along the axis inclined with respect to it. As another aspect, when the cross section obtained by cutting the cushioning material 4 in the xz plane perpendicular to the y direction is viewed, the holes having the same shape are not always formed, and the holes 5 have different shapes depending on the position of the cross section. May be formed. Further, the axial direction of the substantially cylindrical shape formed by the outer shape of the cushioning material 4 coincides with the y direction, and the hole 5 formed therein is formed along the axis inclined with respect to the y direction. May be.

Next, the shape of the hole 5 formed in the holder 6 will be described. FIG. 2A is a side view of the end surface of the roll-shaped thermal transfer image receiving sheet body 1 of FIG. 1 viewed from the y direction. 2B is a cross-sectional view of the roll-shaped thermal transfer image receiving sheet 1 of FIG. 1 taken along a yz plane parallel to a straight line in the z direction which is the vertical direction intersecting the axis and the y axis which is the axis. is there.

As shown in FIG. 2A, on the side surface of the end surface of the roll-shaped thermal transfer image-receiving sheet body 1 viewed from the y direction, two arcs are vertically stacked on the holder 6, and a shape like a gap between them is formed. A cushioning material 4 having a hole 5 formed by a contour line is arranged. In the present embodiment, an arc having a smaller radius is formed on the upper side, and an arc having a larger radius than the upper side is formed on the lower side thereof as a part of the contour line of the hole 5, and the contours in which the ends of both arcs are connected It is a line. When the upper and lower arcs are extended to form a circle, the circumferences of the arcs are in a positional relationship such that they overlap each other.

The hole, which is arranged on the upper side and has a circular arc with a smaller radius in the contour line, is a winding-side bobbin storage hole 52 that is a hole for storing and holding a winding-side bobbin 13 described later. Similarly, the hole, which is arranged on the lower side and has an arc having a larger radius as a contour line, is a supply-side bobbin accommodating hole 51 which is a hole for accommodating and holding a supply-side bobbin 12 described later. The winding-side bobbin storage hole 52 and the supply-side bobbin storage hole 51 are connected to each other by a connecting hole 53 to form a second hole portion 56 that is an integral hole. Further, on both sides of the connection hole 53, a protrusion 54 which is a protrusion of the cushioning material 4 is formed. The protrusion 54 can prevent the winding-side bobbin 13 and the supply-side bobbin 12, which will be described later, from being pressed against each other more than necessary.

The cushioning material 4 of the holder 6 is arranged outside and has an outer shape that is substantially the same as the inner diameter of the paper tube 3 around which the thermal transfer image receiving sheet 2 is wound. The holder 6 may be removably fitted in the paper tube 3 in the y direction which is the axial direction, or may be fixed to the paper tube 3 with an adhesive or the like so as not to be removable. A hole 5 having a contour line including two kinds of arcs having different radii from each other is formed in the upper and lower sides. The arc-shaped hole 5 has a supply-side bobbin 12 around which a heat transfer sheet 14 to be described later is wound, respectively. The winding side bobbin 13 for winding the heat transfer sheet 14 after the heat transfer has a structure that can be removably inserted along the y direction. In the hole 5, not only the thermal transfer sheet 14, the supply side bobbin 12 and the winding side bobbin 13 can be accommodated, but also the free movement of these with respect to the roll-shaped thermal transfer image receiving sheet body 1 can be suppressed. It can be held.

Various materials can be used as the cushioning material 4 of the holder 6 having such a function as having a proper elasticity. For example, as the resin material, polyethylene, polystyrene, polypropylene, polyethylene terephthalate (PET), Use polycarbonate, polyvinyl chloride, polyurethane, polybutyral, acrylonitrile-butadiene-styrene (ABS) resin, acrylonitrile-ethylene-propylene-diene-styrene (AES) resin, and rubber-based materials such as natural rubber and silicone rubber. You can Further, assuming that a thin cushioning material is wound around the supply side bobbin 12 and the winding side bobbin 13, the cushioning material 4 may be made of metal such as aluminum or stainless steel. Further, the cushioning material may be formed by stacking thin paper materials such as cardboard. It is also possible to impart further elasticity by subjecting these to foaming processing, notching processing and the like.

Of the above materials, it is particularly preferable to use expanded polypropylene or ABS. Foamed polypropylene is excellent in elasticity as a cushioning material, processability, and holding properties of a heat transfer sheet and a bobbin. When the foamed polypropylene is used, considering the deformation and holding force when the supply-side bobbin 12 and the winding-side bobbin 13 are stored, the radius of each of the supply-side bobbin 12 and the winding-side bobbin 13 is larger than that of the supply-side bobbin 12 and the winding-side bobbin 13. The holes 5 can be formed so as to have an arc having a slightly smaller radius as a contour line. On the other hand, ABS is a hard plastic that does not have great elasticity like the above materials, but since it is excellent in dimensional accuracy, it has a slightly larger radius arc than the contour of the supply side bobbin 12 and winding side bobbin 13 to be inserted. As described above, the holes 5 can be formed, and stable heat transfer sheet and bobbin holding characteristics can be obtained.

Further, as shown in FIG. 2B, the end surface of the cushioning material 4 of the holder 6 is located inside (right side of the paper) along the y direction with respect to the end surface of the roll-shaped thermal transfer image receiving sheet body 1 (the left end of the paper surface). It is arranged so that. Here, the hole formed in the region on the end surface side of the roll-shaped thermal transfer image receiving sheet 1 where the cushioning material 4 is not arranged is the first hole portion 55, and the hole formed by the cushioning material 4 arranged at the back of the hole 55. Reference numeral 5 is a second hole portion 56 which is slightly smaller than this. The length of the first hole 55 along the y direction may be set arbitrarily, but is determined, for example, in consideration of the structure of the paper flange used when setting the roll-shaped thermal transfer image receiving sheet 1 in the printer. It is preferable.

FIG. 3 is a cross-sectional view showing a state in which the paper flange 20 is fitted into the roll-shaped thermal transfer image receiving sheet body 1, cut under the same conditions as in FIG. 2B. The printer can continuously feed the thermal transfer image receiving sheet 2 from the roll-shaped thermal transfer image receiving sheet body 1 by supporting the paper flange 20 and rotating it. As shown in FIG. 3, by fitting the cap 21 that is a protruding portion near the center of the paper flange 20 into the first hole portion 55 that is the hollow portion of the paper tube 3 of the roll-shaped thermal transfer image receiving sheet body 1, The flange 20 can be fixed integrally with the roll-shaped thermal transfer image receiving sheet body 1. Here, by arranging the cushioning material 4 inside along the y direction so that the cushioning material 4 is not disposed in the portion where the cap 21 fits, the cap 21 collides with the cushioning material 4 and the paper flange 20 is removed. It can prevent that it cannot be fixed. For this reason, it is preferable that the cushioning member 4 is retracted inward by the depth of the cap 21 of the paper flange 20.

(C) Thermal transfer sheet, supply side bobbin and winding side bobbin As shown in FIG. 1, in order to thermally transfer and form a color image or the like on the thermal transfer image receiving sheet 2 by the printer, the thermal transfer sheet 14 is wound around the supply side bobbin 12 It is necessary to set the bobbin combination 10 for the thermal transfer sheet, which is a combination of the above and the take-up side bobbin 13 around which the tip of the thermal transfer sheet 14 is hung, in the printer. In the case of the thermal melting transfer type, the thermal transfer sheet 14 is a sublimation transfer type in which a coloring material is contained on a base material, and a colored transfer layer which can be easily softened and melted by heating to be transferred is formed. In the case of (2), a coloring material (dye) that is sublimated or migrates by heat is carried as a colored transfer layer on the substrate by a suitable binder.

(D) Combination of Rolled Thermal Transfer Image Receiving Sheet and Thermal Transfer Sheet The thermal transfer sheet bobbin combination 10 is as it is, that is, the supply side bobbin 12 around which the thermal transfer sheet 14 is wound and the tip of the thermal transfer sheet 14. It is also convenient for the customer side to package the roll-shaped thermal transfer image receiving sheet body 1 and send it to the customer in the form of being combined with the winding-side bobbin 13 around which the parts are wound. This is because the thermal transfer sheet 14 and the roll-shaped thermal transfer image receiving sheet 2 can be immediately set in the printer.

Therefore, in the present embodiment, as shown in FIG. 1, the roll-side thermal transfer image receiving sheet body 1 includes the supply side bobbin 12 and the winding side bobbin 13 around which the thermal transfer sheet 14 constituting the thermal transfer sheet bobbin combination 10 is wound. Can be inserted into the second hole portion 56 which is the hole 5 of the holder 6 formed by the two arc-shaped contour lines from the end face side of the. As a result, the thermal transfer sheet bobbin combination 10 is housed in the second hole portion of the holder 6 of the roll-shaped thermal transfer image receiving sheet body 1 and is prevented from freely moving due to the elasticity of the cushioning material 4 of the holder 6. It is held by receiving an appropriate external force.

FIG. 4 is a side view and a cross-sectional view of a roll-shaped thermal transfer image-receiving sheet assembly 11 in which the thermal transfer sheet bobbin assembly 10 is housed and held in the roll-shaped thermal transfer image-receiving sheet body 1. FIG. 4A is a side view of the combination 11 of the roll-shaped thermal transfer image receiving sheet and the thermal transfer sheet as seen from the same direction as FIG. 2A, and FIG. 4B shows this in FIG. 2B. It is sectional drawing seen on the same conditions as.

As shown in FIG. 4A, the supply-side bobbin 12 on which the thermal transfer sheet 14 is wound is stored in the supply-side bobbin storage hole 51 in the second hole portion 56 formed in the cushioning material 4 of the holder 6. The bobbin 13 on the winding side is held and held in the bobbin receiving hole 52 on the winding side, and both bobbins are separated by a protrusion 54 so as not to come close to each other by a certain distance or more. The thermal transfer sheet 14 laid over the supply side bobbin 12 and the winding side bobbin 13 is inscribed in the protrusion 54.

As described above, the roll-shaped thermal transfer image receiving sheet body 1 according to the first embodiment of the present disclosure is usually a paper tube 3 that is a region on the winding core side of the thermal transfer image receiving sheet 2 that is wound in a roll shape and becomes a dead space. The supply side bobbin 12 and the take-up side bobbin 13 in which the thermal transfer sheet 14, which is an essential member when performing thermal transfer with a printer, is wound in the through hole portion of the printer not only simply stored but also vibrated or moved carelessly. As a result, the thermal transfer sheet 14 and the bobbin are provided with a holder 6 having a hole having a holding function for suppressing damage and deformation.

Therefore, the thermal transfer sheet 14, the supply-side bobbin 12, and the winding-side bobbin 13 can be efficiently and stably housed and held inside the thermal transfer image-receiving sheet 2 that is wound into a roll, which is then rolled. The heat transfer image-receiving sheet body and the heat transfer sheet can be integrated as a combined body 11. As a result, the volume related to packaging and transportation can be reduced, so that the transportation efficiency can be increased, the transportation cost can be reduced, and the thermal transfer sheet 14, the supply side bobbin 12 and the winding side bobbin 13 can be sufficiently protected. Further, a high quality thermal transfer image or the like can be formed on the thermal transfer image receiving sheet 2 at low cost. Further, by making the length of the thermal transfer image receiving sheet 2 and the length of the thermal transfer sheet 14 correspond to each other, it is possible to reduce waste such that only one member is left over.

In the present embodiment, the heat transfer sheet bobbin combination 10 in which the supply-side bobbin 12 around which the heat transfer sheet 14 is wound and the take-up side bobbin 13 are combined is held to be housed in the roll-shaped heat transfer image receiving sheet 1. The configuration of the tool 6 has been described. However, as in a modified example to be described later, as for the winding-side bobbin 13, the customer may store the used bobbin, and only the supply-side bobbin 12 on which the thermal transfer sheet 14 is wound is rolled. In some cases, it may be packaged in the sheet body 1 and sent. In this case, the content of the present embodiment can be applied except that the winding-side bobbin storage hole 52, which is a storage hole for the winding-side bobbin 13, is not required in the cushioning member 4 of the holder 6.

2. Modifications The first embodiment described above can be variously modified and changed, and these are also within the scope of the present disclosure. Below, some modified examples are given.

(A) Modification (1)
FIG. 5A is a side view showing a roll-shaped thermal transfer image receiving sheet body 1A in which the hole shape of the holder is different when the end surface of the roll-shaped thermal transfer image receiving sheet body 1 of the first embodiment is viewed. is there. Further, FIG. 5B is a side view showing a combination 11A of the roll-shaped thermal transfer image receiving sheet body and the thermal transfer sheet in which the thermal transfer sheet bobbin combination body 10 is housed and held by the roll-shaped thermal transfer image receiving sheet body 1A. is there.

As shown in FIG. 5(a), on the side surface of the end surface of the roll-shaped thermal transfer image receiving sheet 1A viewed from the y direction, two arcs are vertically stacked on the holder 6A, and the shape is such that they are connected to each other. A cushioning material 4A having a hole 5A formed by a contour line is arranged. Moreover, in this modification, an arc having a smaller radius on the upper side and an arc having a larger radius on the lower side than on the upper side are formed as the contour lines of the second hole portion 56A that is the hole 5A, and both arcs are formed. It is a contour line where the ends are connected. This is different from the first embodiment in that the upper and lower circular arcs have a positional relationship such that when the circular arcs are extended to form a circle, their circumferences do not overlap each other.

The winding side bobbin storage hole 52A arranged on the upper side stores and holds the winding side bobbin 13, and the supply side bobbin storage hole 51A arranged on the lower side stores and holds the supply side bobbin 12. Has been done. The connecting hole 53A connecting between them has a narrow width so that the supply-side bobbin 12 and the winding-side bobbin 13 do not contact each other, and the projections of the cushioning material 4A are provided on both sides of the connecting hole 53A. Projections 54 are formed respectively. With such a connecting hole 53A, it is possible to secure a path for the thermal transfer sheet 14 hung on the supply side bobbin 12 and the winding side bobbin 13, and at the same time, the winding side bobbin storage hole 52A and the supply side bobbin storage hole. 51A is easily deformed, and its elasticity increases, so that the holding effect of the winding side bobbin 13 and the supply side bobbin 12 can be enhanced. However, the connection hole 53A may not be provided, and the winding-side bobbin storage hole 52A and the supply-side bobbin storage hole 51A may form separate holes that are not connected to each other.

In this modification, since the supply-side bobbin 12 around which the thermal transfer sheet 14 is wound and the winding-side bobbin 13 around which the thermal transfer sheet 14 after thermal transfer is wound are separated from each other, the roll-shaped thermal transfer image receiving sheet body and the thermal transfer sheet are separated from each other. It is possible to further reduce the risk of deformation of the thermal transfer sheet 14 and the bobbin due to pressing of both bobbins due to external force or vibration during packaging and transportation as the combination 11A. However, since the radius of each arcuate hole needs to be designed to be slightly smaller than that of the first embodiment, it is necessary to design the hole shape in consideration of the radius of the paper tube 3 and the thickness of the thermal transfer sheet 14. There is.

(B) Modified example (2)
Next, a modified example (2) will be described. FIG. 6A is a side view showing a roll-shaped thermal transfer image receiving sheet 1B in which the hole shape of the holder when the end surface of the roll thermal transfer image receiving sheet is viewed is different from that described above. 6B is a side view showing a combination 11B of the roll-shaped thermal transfer image receiving sheet body and the thermal transfer sheet in which the bobbin combination body 10 for the thermal transfer sheet is housed and held by the roll-shaped thermal transfer image receiving sheet body 1B. is there.

As shown in FIG. 6(a), on the side surface of the end surface of the roll-shaped thermal transfer image receiving sheet 1B viewed from the y direction, two arcs are vertically stacked on the holder 6B, and the shape is such that the spaces between them are connected. A cushioning material 4B having a hole 5B formed by a contour line is arranged. An arc having a smaller radius on the upper side and an arc having a larger radius on the lower side than the upper side are formed as the contour lines of the second hole portion 56B that is the hole 5B, and the contours to which the ends of both arcs are connected are formed. Although it is a line, it differs from the first embodiment in that one of them forms a tangent line of each arc.

That is, the winding side bobbin storage hole 52B arranged on the upper side stores and holds the winding side bobbin 13, and the supply side bobbin storage hole 51B arranged on the lower side stores the supply side bobbin 12. , Retained. The connecting hole 53B connecting between them is arranged so as to separate them so that both bobbins do not abut each other. The protrusion 54B is provided only on one side of the connecting hole 53B, and is not a protrusion on the opposite side, but a common tangent portion 57 of each arc of the winding side bobbin storage hole 52B and the supply side bobbin storage hole 51B.

It is also possible to reduce the risk of damage caused by bending the heat transfer sheet 14 that has been cut.

(C) Modified example (3)
Next, the modified example (3) will be described. FIG. 7A is a side view showing the roll-shaped thermal transfer image receiving sheet body 1C. Further, FIG. 7B is a cross-sectional view of the roll-shaped thermal transfer image-receiving sheet body 1C taken along the yz plane.

As shown in FIGS. 7(a) and 7(b), the roll-shaped thermal transfer image receiving sheet body 1C is a so-called coreless type thermal transfer image receiving sheet body that does not have the paper tube 3, and the thermal transfer image receiving sheet 2 is attached to the holder 6C. It is wound so as to make direct contact. As shown in FIG. 7B, the holder 6C has a first cushioning material portion 41, which is a thin portion of the cushioning material 4C, in the vicinity of the end face of the roll-shaped thermal transfer image receiving sheet body 1C in a cross section taken along the yz plane. , A second cushioning material portion 42, which is a thicker portion on the inner side when viewed in the y direction, and a step portion 43 therebetween. As described above, by forming the step portion 43 by reducing the thickness of the buffer material 4C near the end surface of the roll-shaped thermal transfer image receiving sheet body 1C, the paper flange cap is attached when the paper flange is attached and set in the printer. Can be done smoothly. The step portion 43 may have a tapered shape as in a modified example described later.

It should be noted that, as shown in FIG. 7A, the winding-side bobbin storage hole 52C arranged on the upper side, the supply-side bobbin storage hole 51C arranged on the lower side, the connecting hole 53C connecting between them, and the protrusion 54C are Although the winding-side bobbin storage hole 52, the supply-side bobbin storage hole 51, the connection hole 53, and the protrusion 54 of the roll-shaped thermal transfer image-receiving sheet body 1 according to the first embodiment have the same structure, these structures are not limited thereto.

It can also be applied when it is not rolled. In this case, since the leading end of the thermal transfer image receiving sheet 2 on the winding core side is fixed in a cylindrical shape, as in the case of the roll-shaped thermal transfer image receiving sheet body having a paper tube, the cylindrical space on the winding core side is formed. The holder 6C can be fitted. When the tip of the thermal transfer image receiving sheet 2 on the winding core side is not fixed in a cylindrical shape, the thermal transfer image receiving sheet 2 may be directly wound around the holder 6C. In any case, by providing a stepped portion or a taper near the end surface of the roll-shaped thermal transfer image receiving sheet 1C, the arrangement and shape formed by the paper tube and the holder in other embodiments or modified examples can be obtained. It can be replaced only by the holder 6C. By not using the paper tube, it is possible to reduce the number of constituent parts of the roll-shaped thermal transfer image-receiving sheet body, reduce the cost of the member, and suppress the generation of extra waste members.

(D) Modified example (4)
Next, a modified example (4) will be described. FIG. 8 is a cross-sectional view of the roll-shaped thermal transfer image-receiving sheet body 1D according to the modification, taken along the yz plane.

As shown in FIG. 8, the holder 6D of the roll-shaped thermal transfer image receiving sheet 1D has a taper portion 44 at the end of the cushioning material 4D, which is the end surface portion of the holder 6D, in the cross section taken along the yz plane including the axis. It is provided. The holes 5D formed in the holder 6D become smaller from the end surface of the roll-shaped thermal transfer image receiving sheet 1D inward along the y direction, that is, in the cross section of FIG. It is provided with a taper portion 44 so that the distance to the 5D contour line becomes gradually smaller. For example, in FIG. 8, as the distance from the y-axis to the taper portion 44 which is the contour line of the cushioning material 4D of the holder 6D, the distance on the end surface side (left side of the paper surface) of the roll-shaped thermal transfer image receiving sheet body 1D is d1. Also, when the distance from the end face side (the right side of the paper surface) is d2, the taper portion 44 is formed with an inclination such that d2 is smaller than d1.

As a result, the first hole portion 55 in the region where the cushioning material 4D is not arranged and the second hole portion 56D which is the hole 5D in the region where the cushioning material 4D is arranged are not tapered and have a smooth taper. It will be connected. As described above, since the end portion of the cushioning material 4D of the holder 6D has the taper portion 44, the roll-side thermal transfer image receiving sheet body 1D is wound along the y direction on the supply side bobbin 12 and the winding side. When the take-up bobbin 13 is stored, it can be stored smoothly without hitting a step, and the risk of damage or deformation of the thermal transfer sheet 14 or the cushioning material can be reduced.

A cushioning material 4E having a hole 5E formed by a contour line having a shape connected between them is arranged. For example, the winding-side bobbin storage hole 52E arranged on the upper stage side and the supply-side bobbin storage hole 51E arranged on the lower stage side each have a part of a substantially regular octagon whose one side length is different as a contour line. ing. The connecting hole 53E and the protruding portion 54E connecting between them have a structure similar to that of the connecting hole 53 and the protruding portion 54 of the roll-shaped thermal transfer image receiving sheet body 1 of the first embodiment.

The roll-shaped thermal transfer image-receiving sheet body 1E in which the winding-side bobbin 13 and the supply-side bobbin 12 which are the bobbin combination bodies 10 for the thermal transfer sheet are housed is shown in FIG. As shown in b), the circles that are the cross sections of the winding-side bobbin 13 and the supply-side bobbin 12 have a substantially regular octagonal side of the winding-side bobbin storage hole 52E and a substantially regular octagon of the supply-side bobbin storage hole 51E, respectively. It is stored so that it is inscribed on the side of. Therefore, the external forces applied to the winding side bobbin 13 and the supply side bobbin 12 are substantially equal, and the risk of damaging or deforming the bobbin can be reduced.

As in the present modification, the hole shape for storing and holding the supply side bobbin 12 and the winding side bobbin 13 is not limited to the shape including an arc, and any bobbin can be stored and held stably. Various polygonal shapes may be used, and various polygonal shapes such as a substantially regular hexagon, a regular regular heptagon, and a regular regular dodecagon may be used. Further, the shape is not limited to a polygon and may be a hole formed by a contour line formed with a large number of irregularities along an arc or a shape formed by a combination of a large number of straight lines and curved lines.

(F) Modification (6)
Next, a modified example (6) will be described. The above-described embodiments and modifications are all related to the holder structure of the roll-shaped thermal transfer image receiving sheet body 1 for accommodating and holding both the supply side bobbin 12 and the winding side bobbin 13, which are the bobbin combination bodies 10 for the thermal transfer sheet. However, the present disclosure is not so limited. It is essential that the thermal transfer sheet 14 used when performing thermal transfer with the printer is wound on the supply side bobbin 12 at least for convenience of setting, but in order to wind up the used thermal transfer sheet after completion of thermal transfer. As for the winding-side bobbin 13, the customer can reuse the previously used bobbin. In this case, only the supply-side bobbin 12 around which the thermal transfer sheet is wound needs to be packaged in the roll-shaped thermal transfer image receiving sheet 1.
