  The image receiving paper roll according to the embodiment of the present invention will be described below with reference to the drawings.

First Embodiment First, an image receiving paper roll according to a first embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the image receiving paper roll 1 includes a winding core 10 described later and an image receiving paper 2 wound around the winding core 10.

  Among these, the winding core 10 includes a core body 11 formed in a cylindrical shape, a cushion layer 12 made of a foamed resin provided over the entire outer surface of the core body 11, and the cushion layer 12. A smoothing layer 13 that is provided over the entire area of the outer surface and smoothes the outer surface of the cushion layer 12 is provided.

  As shown in FIG. 2, the cushion layer 12 is formed by winding a cushion sheet 12 a made of foamed resin formed in a band shape around the outer surface of the core body 11 a plurality of times. Thus, in the cushion layer 12, the boundary (winding line) 12b located between the mutually adjacent cushion sheets 12a is formed. In the present embodiment shown in FIG. 2, the cushion sheet 12 a is wound obliquely with respect to the central axis of the core body 11 and bonded to the outer surface of the core body 11.

  Further, the smoothing layer 13 is formed by winding a smoothing sheet 13 a formed in a belt shape around the outer surface of the cushion layer 12 a plurality of times. Thus, in the smoothing layer 13, the boundary (winding line) 13b located between the smoothing sheets 13a adjacent to each other is formed. In the present embodiment shown in FIG. 2, the smoothing sheet 13 a is wound obliquely with respect to the central axis of the core body 11 and adhered to the outer surface of the cushion layer 12.

  The boundary 12b between the cushion sheets 12a and the boundary 13b between the smoothing sheets 13a are arranged at different positions. Accordingly, it is possible to prevent the boundary 12b between the cushion sheets 12a and the boundary 13b between the smoothing sheets 13a from overlapping and forming streaks or the like on the image receiving paper 2 by these boundaries 12b and 13b. In the present embodiment shown in FIG. 2, the boundary 12b between the cushion sheets 12a and the boundary 13b between the smoothing sheets 13a are alternately arranged at equal intervals, but the boundary 12b between the cushion sheets 12a If the boundary 13b between the smoothing sheets 13a is arrange | positioned in a mutually different position, it will not be restricted to this.

  The total thickness of the cushion layer 12 and the smoothing layer 13 is preferably 1 mm or more and 4 mm or less. As a result, the cushion effect of the cushion layer 12 can be exhibited, and the cushion material 12a can be wound around the outer surface of the core body 11 and securely adhered.

  The 10-point average roughness RzJIS (or 10-point average value SRz) of the outer surface of the smoothing layer 13 is preferably 50 μm or less. Thereby, it is possible to prevent the unevenness of the image receiving paper 2 from being formed and to smooth the image receiving paper 2. Here, the ten-point average roughness is defined in JIS-B0601-2001.

  As shown in FIG. 4, the image receiving paper 2 has a base sheet 2b formed in a belt shape, and a receiving layer 2c provided on both sides of the base sheet 2b and receiving ink, It is wound around the outer surface of the smoothing layer 13 of the winding core 10. Note that the thickness of the image receiving paper 2 is preferably 150 μm to 350 μm.

  Next, the material of each component will be described.

  The core body 11 of the winding core 10 is preferably made of paper. This makes it easy to recycle the core body 11 after disposal.

  The cushion sheet 12a is preferably made of a foamed resin, in particular, a polyethylene foam, but a polyurethane foam can also be used. Thus, by making the cushion sheet 12a from the foamed resin, the wound image receiving paper 2 can be stably held, and the image receiving paper 2 is wound while the image receiving paper roll 1 is being conveyed. While preventing collapse, it is possible to prevent image misalignment or the like on the image receiving paper 2 during printing.

  The smoothing sheet 13a is preferably made of kraft paper or high-quality paper. In this case, the smoothing layer 13 made of the smoothing sheet 13a can be easily recycled after disposal. However, the present invention is not limited to this, and the smoothing sheet 13a may be made of resin.

  Next, the operation of the present embodiment having such a configuration, that is, a method for winding the image receiving paper 2 around the winding core 10 will be described.

  First, as shown in FIG. 1, a core body 11 formed in a cylindrical shape, a cushion layer 12 made of foamed resin provided on the outer surface of the core body 11, and provided on the outer surface of the cushion layer 12. A winding core 10 having a smoothing layer 13 for smoothing the outer surface of the cushion layer 12 is prepared.

  In this case, first, a cylindrical core body elongated body (not shown) having a width corresponding to the plurality of core bodies 11 is prepared. Next, the cushion sheet 12a is wound around the outer surface of the long body of the core body a plurality of times with respect to the central axis of the long body of the core body to form the cushion layer 12. The smoothing sheet 13 a is wound around the outer surface of the cushion layer 12 a plurality of times obliquely with respect to the central axis of the core body 11, thereby forming the smoothing layer 13. At this time, the smoothing sheet 13a is wound so that the boundary 13b between the smoothing sheets 13a is at a position different from the boundary 12b between the cushion sheets 12a. In this way, a wound core long body (not shown) is formed. Then, this winding core elongate body is cut | disconnected and the winding core 10 shown in FIG. 1 and FIG. 2 is obtained.

  Next, as shown in FIG. 3, the base end 2 a of the belt-shaped image receiving paper 2 is joined to the outer surface of the smoothing layer 13 of the winding core 10. In this case, the base end 2 a of the image receiving paper 2 may be bonded to the smoothing layer 13 by interposing the double-sided tape 3 between the base end 2 a of the image receiving paper 2 and the smoothing layer 13. Alternatively, for example, a cellophane tape (not shown) is pasted over the surface of the base end 2 a of the image receiving paper 2 and the outer surface of the smoothing layer 13 so that the base end 2 a of the image receiving paper 2 is the smoothing layer 13. You may make it join to.

  Thereafter, the take-up core 10 is rotated and the image receiving paper 2 is taken up. In this manner, the image receiving paper 2 is wound around the winding core 10 to form the image receiving paper roll 1 (see FIG. 1).

  On the other hand, when the image receiving paper 2 is fed out from the image receiving paper roll 1, the winding core 10 may be rotated in the direction opposite to that at the time of winding.

  Thus, according to the present embodiment, the image receiving paper 2 is wound around the outer surface of the cushion layer 12 via the smoothing layer 13. In this case, the smoothing layer 13 can smooth the outer surface of the cushion layer 12 made of foamed resin having a large number of minute holes. For this reason, it is possible to prevent minute irregularities from being formed on the image receiving paper 2 by the foamed resin constituting the cushion layer 12. For this reason, the image receiving paper 2 can be wound while maintaining a smooth state.

  Further, according to the present embodiment, as described above, the base end 2 a of the image receiving paper 2 is joined to the smoothing layer 13 via the double-sided tape 3. Here, since the ten-point average roughness of the outer surface of the smoothing layer 13 is 50 μm or less, the bonding area between the smoothing layer 13 and the double-sided tape 3 can be increased. Thus, the bonding strength between the double-sided tape 3 and the smoothing layer 13 can be improved. As a result, the base end 2a of the image receiving paper 2 can be reliably bonded to the smoothing layer 13.

  Further, according to the present embodiment, the image receiving paper 2 having a thickness of 150 μm to 350 μm is wound around the outer surface of the cushion layer 12 having a thickness of 1 mm to 4 mm via the smoothing layer 13, and the smoothing is performed. The base end 2 a of the image receiving paper 2 is bonded to the layer 13. In this case, the base end 2 a of the image receiving paper 2 is pressed more strongly toward the central axis of the core body 11 than the other portions of the image receiving paper 2 when the image receiving paper 2 is wound thereon. As a result, the portion of the cushion layer 12 corresponding to the base end 2a of the image receiving paper 2 is compressed, and a step is prevented from being formed between the base end 2a of the image receiving paper 2 and the smoothing layer 13. be able to. For this reason, it is possible to prevent streaks from being formed on the image receiving paper 2 and to wind the image receiving paper 2 while maintaining a smooth state. As a result, it is possible to print on the image receiving paper 2 with high accuracy.

  Further, according to the present embodiment, the base end 2 a of the image receiving paper 2 is joined to the smoothing layer 13 by the double-sided tape 3 (or cellophane tape). Even in this case, as described above, the base end 2a portion of the image receiving paper 2 is pressed more strongly toward the central axis of the core body 11 than the other portions of the image receiving paper 2, and the corresponding cushion layer 12 The part is compressed. As a result, the level difference caused by the double-sided tape 3 can be reduced, the formation of streaks on the image receiving paper 2 can be prevented, and the image receiving paper 2 can be wound while maintaining a smooth state.

  Furthermore, according to the present embodiment, the image receiving paper 2 having the receiving layer 2c on both sides can be wound while maintaining a smooth state as described above. For this reason, even if the receiving layer 2c is on the base end 2a side of the image receiving paper 2 and faces the core body 11, the smooth state can be reliably maintained and printing can be performed with high accuracy.

  In the present embodiment, the cushion layer 12 is formed by winding the cushion sheet 12 a obliquely around the outer surface of the core body 11 a plurality of times, and the smoothing layer 13 is formed on the outer surface of the cushion layer 12. An example in which the smoothing sheet 13a is formed by winding it multiple times obliquely has been described. However, the present invention is not limited to this, and the cushion sheet 12 a and the smoothing sheet 13 a may be wound a plurality of times in a direction orthogonal to the central axis of the core body 11. Alternatively, the cushion layer 12 and the smoothing layer 13 may be formed without forming a boundary by wrapping with the cushion sheet 12a and the smoothing sheet 13a having substantially the same width as the width of the core body 11, respectively. May be.

Second Embodiment Next, an image receiving paper roll according to a second embodiment of the present invention will be described with reference to FIG.

  The image receiving paper roll in the second embodiment shown in FIG. 5 is mainly different in that notch notches are formed at both ends of the core body, and other configurations are the same as those in the first embodiment shown in FIGS. This is substantially the same as the embodiment. In FIG. 5, the same parts as those of the first embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 5, a notch 14 is formed at both ends of the core body 11 of the take-up core 10 for use in mounting on the printer. In FIG. 5, only one end of the core body 11 is shown.

  The cushion layer 12 is formed over the entire area of the outer surface of the core body 11 so as to cover the notch 14. A smoothing layer 13 is formed over the entire area of the outer surface of the cushion layer 12, and the image receiving paper 2 is wound around the outer surface of the smoothing layer 13.

  As described above, according to the present embodiment, the cushion layer 12 having a thickness of 1 mm to 4 mm is provided on the outer surface of the core body 11 in which the notch 14 is formed at both ends, and on the cushion layer 12, The image receiving paper 2 having a thickness of 150 μm to 350 μm is wound through the smoothing layer 13. In this case, concave portions are formed at both ends of the core body 11 by the cutout notches 14, but the influence of the concave portions on the image receiving paper 2 can be mitigated by the cushion layer 12. As a result, it is possible to prevent streaks or the like from being formed on the portion of the image receiving paper 2 wound on the notch 14 and to wind the image receiving paper 2 while maintaining a smooth state. As a result, it is possible to print on the image receiving paper 2 with high accuracy.
