The reflected light from the resin is detected.

  Next, with reference to FIGS. 6 and 16 to 22, the function of the paper intrusion prevention member (the ear portion 71 and the ear portion 72), which is a main part of the present invention, will be described. 18 is a cross-sectional view taken along line CC in FIG. 16 of the paper package 9, and FIG. 19 is the paper in FIG. 16 in which the paper 7 is used and the number of sheets is reduced. FIG. 6 is a cross-sectional view in the direction of the arrows along the line C-C of the package 9. 20 is a cross-sectional view taken along the line C-C of the paper package 9 in FIG. 16 in a state in which the paper 7 is not in the interior. FIG. FIG. 22 is a vertical cross-sectional view of the paper package 9 in a state where the paper 7 is inserted from the opening 49 of the paper package 9.

  As shown in FIGS. 6 and 16, when the lid portion 44 of the paper package 9 is folded, the ear portions folded from both ends of the tongue portion 70 in the paper package 9 as shown in FIG. 18. 71 and ears 72 press the surface of the paper 7 stored in the paper package 9. The pressing force of the ear portion 71 and the ear portion 72 is generated when the ear portion 71 and the ear portion 72 try to elastically return due to the elasticity of the package material 8. Further, even when the number of sheets stored in the sheet package 9 is small, the ear 71 and the ear 72 are elastically restored and press the surface of the sheet 7 as shown in FIG. Accordingly, it is possible to prevent the paper 7 from falling from the paper package 9 when the lid portion 44 of the paper package 9 is folded.

  Further, when the user pulls out all of the paper 7 from the paper package 9 or when the opening of the paper package 9 is shaken downward with the lid 44 folded back, the paper There is a case where the entire sheet 7 comes out of the package 9 and falls. In this case, as shown in FIG. 20, the ear 71 and the ear 72 are elastically restored by the elasticity of the package material 8 at the fold, and the ear 71 and the tip of the ear 72 are in contact with the bottom 40. become. In this state, when the paper 7 is inserted into the paper package 9 through the opening 49 as shown in FIG. 21, the ear 71 and the ear 72 are connected to the bottom 40 (first portion) and the first as shown in FIG. Located in the space between the exterior part 50 (second part), the side ends of the ear part 71 and the ear part 72 abut against the end part in the insertion direction of the paper 7, and the end part of the paper 7 is in the side wall part 43. It becomes impossible to contact. Accordingly, as shown in FIG. 22, the sheet 7 cannot be completely returned to the original storage position of the sheet package 9, and a part of the sheet 7 protrudes from the sheet package 9. Therefore, the dropped paper 7 cannot be returned to the normal storage position of the paper package 9 from the opening 49, and it is possible to prevent the paper 7 to which dust or dirt is attached from being reused.

  Next, a second embodiment of the paper package 9 will be described with reference to FIGS. FIG. 23 is a developed view of the paper package 9 according to the second embodiment as viewed from the outside of the package material 8, and FIG. 24 is a perspective view showing a state in the middle of assembling the paper package 9 according to the second embodiment. FIG.

  As shown in FIG. 23, since the packaging material 8 of the paper package 9 of the second embodiment is almost the same as the packaging material 8 of the first embodiment, only different parts will be described. As shown in FIG. 23, a rectangular tongue 70 is also provided in the package material 8 of the paper package 9 of the second embodiment. When the tongue 70 is folded back to the middle portion in the longitudinal direction, the rectangular ear 73 and the ear 74 that have the same function as the ear 71 and the ear 72 of the first embodiment are cut (straight). It is provided with a crease (two-dot chain line). In the second embodiment, as shown in FIG. 24, the tongue portion 70 is raised and bent, and the ear portions 73 and 74 are bent, whereby the paper 7 is fed by the ear portion 73 and the ear portion 74. By pressing, the same effects as the first embodiment can be obtained.

  Next, a third embodiment of the paper package 9 will be described with reference to FIG. FIG. 25 is a development view seen from the outside of the package material 8 of the paper package 9 according to the third embodiment.

  As shown in FIG. 25, since the packaging material 8 of the paper package 9 of the third embodiment is almost the same as the packaging material 8 of the first embodiment, only different parts will be described. As shown in FIG. 25, the package member 8 of the paper package 9 according to the third embodiment is also provided with a rectangular tongue 70, but the ear is not provided on the tongue 70. In the third embodiment, the rectangular ear portion 47 and the ear portion 48 are provided with a cut (straight line) and a crease (two-dot chain line) in the bottom portion 40. Therefore, before placing the paper 7 on the bottom 40 as the first part, the ear 47 and the ear 48 of the bottom 40 are raised and bent, and the paper 7 is placed thereon, whereby the ear 7 47 and the ear | edge part 48 can press the paper 7, and there can exist an effect similar to 1st embodiment.

  Next, a fourth embodiment of the paper package 9 will be described with reference to FIG. FIG. 26 is a development view seen from the outside of the package material 8 of the paper package 9 according to the fourth embodiment.

  As shown in FIG. 26, the packaging material 8 of the paper package 9 according to the fourth embodiment has almost the same shape as the packaging material 8 according to the first embodiment, and therefore only different parts will be described. As shown in FIG. 26, the package member 8 of the paper package 9 of the fourth embodiment is also provided with a rectangular tongue 70, but the ear is not provided on the tongue 70. In the fourth embodiment, the rectangular ear portion 57 and the ear portion 58 are provided with a cut line (straight line) and a fold line (two-dot chain line) in the first exterior part 50 as the first part. Therefore, by placing the sheet 7 on the bottom portion 40 and then folding the first exterior portion 50 before the first exterior portion 50 is folded, the ear portion 57 and the ear portion 58 are bent and folded. The ear portion 57 and the ear portion 58 press the paper 7, and the same effects as in the first embodiment can be obtained.

  Next, the paper package 9 according to the fifth embodiment will be described with reference to FIG. FIG. 27 is a development view seen from the inside of the package material 8 of the paper package 9 according to the fifth embodiment. The shape of the package material 8 of the fifth embodiment is the same as that of the package material 8 of the first embodiment shown in FIG. 8 except that the boundary 401 between the bottom 40 and the side wall 41 is different. A perforation is formed at the boundary 402 between the bottom 40 and the side wall portion 42, and a perforation is also formed at the boundary 403 between the bottom 40 and the side wall portion 43. It is a point.

  Normally, the package material 8 is subjected to a crease process for embossing a semi-cylindrical shape from the outer surface to the inner surface at the boundary of the package material 8 when it is folded. Thereby, it becomes easy to bend | fold a boundary as a crease | fold. And when it folds in the boundary where the crease process by this embossing was given, the part 410 (refer FIG. 30) which rose along the crease is formed inside the crease. The boundary 401 between the bottom portion 40 and the side wall portion 41, the boundary 402 between the bottom portion 40 and the side wall portion 42, and the boundary 403 between the bottom portion 40 and the side wall portion 43 are also usually subjected to crease processing by this semi-cylindrical embossing. When bent at each boundary, a raised portion 410 (see FIG. 30) is formed inside each fold. This is because the inner part of the crease is compressed when it is folded, so that it rises in search of a refuge. Inside the raised part, the fiber of the package material is somewhat broken, and the density of the fiber is slightly lower than the other parts. The bottom 40 and the raised portion 410 (see FIG. 30) formed on the boundary 401 are adjacent to each other, and a narrow gap 411 is formed between them. The sheet 7 may be caught in the gap 411. The same applies to the raised portion formed at the bottom 40 and the boundary 402 and the raised portion formed at the bottom 40 and the boundary 403. Once a sheet is caught in the gap, the printing apparatus 1 may not be able to feed out the sandwiched sheet. Note that the only sheet that may be pinched is the lowermost sheet 7 facing the bottom 40. In order for the paper 7 to be sandwiched, a surface with the package material 8 for sandwiching the paper 7 and a raised portion adjacent to the surface are necessary as described above, and the paper 7 is in a state parallel to the surface. It is easy to get pinched when in contact. Further, when the edge of the sheet 7 comes into contact with a bulging portion that continues in a straight line, the sheet 7 is likely to be pinched. In that respect, the size of the sheet storage unit 6 according to the present embodiment as viewed from above is substantially the same as the sheet 7 stored inside, and the sheet 7 has an edge at the inner wall of the sheet storage unit 6 or the package material 8. Therefore, the edge of the sheet 7 is likely to come into parallel contact with the bulging portion that continues in a straight line. The lowermost sheet 7 has the effect of gravity, the influence of the ears 71 and 72 urging the sheet 7 downward on the upstream side in the sheet conveyance direction, and the biasing spring 19 on the downstream side in the sheet conveyance direction. 7 is pressed against the bottom 40 due to the effect of biasing 7 downward. Even in the same lowermost sheet 7, the portion biased downward and the portion biased downward tend to be pinched more easily.

  However, the paper package 9 has a lid base portion 44a that is folded back to the back side when the paper package 9 is mounted. The length of the lid base 44a in the transport direction is about one third of the length of the paper package 9 in the transport direction. Accordingly, the bottom 40 is formed to be short, and the side wall is also only part of the bottom 40, so that the length of the paper package 9 in the transport direction is about 3 from the downstream end of the paper package 9 in the transport direction. In the part up to 1 / upstream, there is no crease parallel to the transport direction on the lower surface, and there is no raised part. The urging spring 19 is configured to have a strong urging force at the downstream end in the conveyance direction of the paper package 9 and to become weaker toward the upstream side. Therefore, there is a possibility that the paper 7 may be pinched by the biasing spring 19 biasing the paper 7 downward on the downstream side in the paper transport direction. The ear 71 and the ear 72 on the upstream side in the paper transport direction face the paper 7 downward. By energizing, it is smaller than the possibility that the sheet 7 is caught.

  In contrast to the paper package 9 using the package material 8 subjected to the normal crease processing, in the paper package of this embodiment, the boundary 401 between the bottom 40 and the side wall 41 and the bottom 40 and the side wall 42 as described above. Perforations are formed at a boundary 402 between the bottom 40 and the boundary 403 between the bottom 40 and the side wall 43. As an example, as shown in FIG. 31, the perforation 412 makes it easy to bend the side wall portion 41 with respect to the bottom portion 40, and a raised portion is formed on the inner side of the fold line that is folded at the perforated boundary. Not. Similarly, the perforation makes it easy to bend the side wall portions 42 and 43 with respect to the bottom portion 40, and no bulging portion is formed on the inside of the fold that is bent at the perforated boundary. Therefore, unlike the sheet package 9 subjected to normal crease processing, the lowermost sheet 7 facing the bottom 40 has a boundary between the bottom 40 and the side wall 41, a boundary between the bottom 40 and the side wall 42, and a bottom. It can prevent being pinched by the boundary of 40 and the side wall part 43. FIG. In the package material 8 of the fifth embodiment, the boundary 404 between the side wall portion 41 and the first exterior portion 50, the boundary 405 between the side wall portion 42 and the second exterior portion 60, the side wall portion 43 and the tongue portion 70. The boundary 406 is formed with a normal bending process that is embossed into a semi-cylindrical shape.

  In the paper package 9 of the present embodiment, the perforations are the boundary 401 between the bottom 40 and the side wall 41 on the lower surface of the paper package 9, the boundary 402 between the bottom 40 and the side wall 42, and the bottom 40 and the side wall 43. Is provided at the boundary 403 of the bottom 40 facing the ears 71 and 72 with the paper 7 sandwiched therebetween, and the ears 71 and the ears 72 affect the paper 7 downward. It may be applied only to the strong boundary 403. At that time, the process may be performed only on the boundary of the bottom 40 facing the ears 71 and 72 with the paper 7 sandwiched therebetween, in the vicinity of the ear 71 and the vicinity of the ear 72 on the boundary 403. Further, the perforation has the sheet 7 sandwiched between the ears 71 and the edge part 72 on the upstream side of the boundary 402 in the vicinity of the ears 71 at the boundary 402 of the bottom 40 facing the ears 71 with the sheet 7 sandwiched therebetween. You may make it apply to the boundary 403 in the conveyance direction upstream edge part of the boundary 401 which is the vicinity of the ear | edge part 72 in the boundary 401 of the opposing bottom part 40, and the boundary 403.

  Next, the paper package 9 according to the sixth embodiment will be described with reference to FIG. Similarly to the paper package 9 of the fifth embodiment, the paper package 9 of the present embodiment also has a lowermost sheet 7 that faces the bottom 40, the boundary between the bottom 40 and the side wall 41, and the bottom 40 and the side wall 42. And the boundary between the bottom portion 40 and the side wall portion 43. FIG. 28 is a partially enlarged view seen from the inside of the package material 8 of the paper package 9 according to the sixth embodiment. The shape of the package material 8 of the sixth embodiment is the same as that of the package material 8 of the first embodiment shown in FIG. 8, but the difference is that, as shown in FIG. A process is performed in which the boundary 401 with the side wall 41 is cut from the inner side to a depth of about half the thickness of the package material 8 to make it easy to bend (hereinafter referred to as “half-cut process”), and similarly, the bottom 40 A half-cut process is also performed on the boundary with the side wall part 42, and a half-cut process is also performed on the boundary between the bottom part 40 and the side wall part 43. The half-cut process makes it easy to bend the side wall portions 41, 42, 43 with respect to the bottom portion 40, and the side walls 41, 42, 43 are tightly bent with respect to the bottom portion 40, so that they face the bottom portion 40. It is possible to prevent the lowermost sheet 7 from being sandwiched between the boundary between the bottom 40 and the side wall 41, the boundary between the bottom 40 and the side wall 42, and the boundary between the bottom 40 and the side wall 43. In the package material 8 of the sixth embodiment, the boundary between the side wall 41 and the first exterior part 50, the boundary between the side wall part 42 and the second exterior part 60, the side wall part 43 and the tongue part 70. The boundary is subjected to a normal bending process that is embossed into a semi-cylindrical shape.

  Next, the paper package 9 according to the seventh embodiment will be described with reference to FIG. Similarly to the paper package 9 of the fifth embodiment, the paper package 9 of the present embodiment also has a lowermost sheet 7 that faces the bottom 40, the boundary between the bottom 40 and the side wall 41, and the bottom 40 and the side wall 42. And the boundary between the bottom portion 40 and the side wall portion 43. FIG. 29 is a partially enlarged view seen from the inside of the package material 8 of the paper package 9 according to the seventh embodiment. The shape of the packaging material 8 of the seventh embodiment is the same as that of the packaging material 8 of the first embodiment shown in FIG. 8, but the difference is that, as shown in FIG. A pit-like depression having a predetermined depth that does not penetrate the boundary 401 with the side wall portion 41 is provided in a row, and similarly, a pit-like depression is provided in a row at the boundary between the bottom portion 40 and the side wall portion 42. Similarly, pit-shaped depressions are provided in a line at the boundary between the bottom 40 and the side wall 43. By the bending processing by the pit-shaped depressions, the side walls 41, 42, and 43 are easily bent with respect to the bottom 40, and the lowermost sheet 7 facing the bottom 40 has a boundary between the bottom 40 and the side wall 41. In addition, it is possible to prevent being caught between the boundary between the bottom portion 40 and the side wall portion 42 and the boundary between the bottom portion 40 and the side wall portion 43. In the packaging material 8 of the seventh embodiment, the boundary between the side wall 41 and the first exterior part 50, the boundary between the side wall part 42 and the second exterior part 60, and the side wall part 43 and the tongue part 70 are provided. The boundary is subjected to a normal bending process that is embossed into a semi-cylindrical shape. Note that the above-mentioned “perforations”, “half cuts”, and “pit-shaped depressions” correspond to “depressions”.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, the number of ears may be one instead of a pair of left and right. Further, the shape of the ear is not limited to a rectangle, but may be an arbitrary shape such as a trapezoid. In the above embodiment, the side wall portion 42 extends from the bottom portion 40, but the side wall portion 42 extends from the first exterior portion 50, and the second exterior portion 60 extends to the side wall portion 42. It may be provided. Further, in the above embodiment, the side wall 43 extends from the bottom 40, but the side wall 43 extends from the first exterior portion 50, and the tongue 70 extends from the side wall 43. You may make it. In addition, the “perforation”, “half cut”, and “pit-shaped depression” are the boundary between the bottom 40 and the side wall 41, the boundary between the bottom 40 and the side wall 42, and the boundary between the bottom 40 and the side wall 43. It is not necessary to provide all of them, and it may be provided only in a portion where the sheet 7 is easily sandwiched, and the other portion may be subjected to a normal bending process that is embossed into a semi-cylindrical shape. As the portion where the sheet 7 is easily sandwiched, the boundary between the bottom 40 and the side wall 41 facing the front side of the first exterior portion 50 pressed by the pressing plate 18 of the printing apparatus 1, and the boundary between the bottom 40 and the side wall 42. This is a boundary between the bottom portion 40 that is in the vicinity of the portion where the paper is urged by the ear portion and any one of the side wall portions.

  Further, the printing apparatus 1 according to the above embodiment discharges the paper 7 from the gap formed by the upper cover 5 of the main body case 2 and the lid body 10, but the side faces are down unless the gap is blocked.
