Description

  The present invention relates to an image recording medium laminate, an image recording medium package, a method for laminating an image recording medium, and a method for storing an image recording medium, in particular, by laminating a plurality of thick image recording media.

  With the spread of digital cameras and high-quality printers, it has become easier to print photos at home. For example, by using an inkjet printer and dedicated inkjet paper, it is possible to print a high-quality photograph similar to a silver salt photograph. Such photo printing is generally performed on an image recording medium such as dedicated high-quality paper, and such a high-quality image recording medium is widely provided.

  By the way, this type of image recording medium is usually stacked with image recording surfaces facing in the same direction, and a large number of sheets are packaged for sale. The conventional image recording medium is not so thick, and both the front and back surfaces are extremely smooth, so there was no particular problem with this. For example, a plurality of image recording media that are considerably thicker than ordinary paper are used. When thinking about laminating sheets, and when thinking about laminating an image recording medium that has undergone some processing on the back side, the back side faces the image recording surface on the front side. There may be some adverse effects on the image recording surface. For example, the image recording surface may be scratched, peeled off, or soiled. Then, when an image is recorded, it causes deterioration.

  Therefore, when such a possibility is considered, a protective sheet is usually sandwiched between image recording media.

However, if the protective sheet is sandwiched between the image recording media, the entire thickness increases accordingly. Further, since the protective sheet is not supposed to be used for other purposes, the number of sheets used is wasted, resulting in an increase in cost.
Further, since the trouble of sandwiching the protective sheet occurs when the image recording medium is laminated, the productivity is lowered.

  The present invention has been made in consideration of the above circumstances, and provides a set of a plurality of image recording media capable of protecting the entire image recording surface without sandwiching a protective sheet, and a package product thereof. With the goal.

  The invention of claim 1 is an image recording medium laminate formed by laminating a plurality of image recording media whose surfaces are image recording surfaces, wherein the lowermost image recording medium has a lower surface and a upper surface. A plurality of image recording media are stacked in such a manner that the front surface and the front surface and the back surface and the back surface face each other in order.

 The invention of claim 2 is characterized in that, in claim 1, when the surface of the uppermost image recording medium faces upward, a protective sheet is laminated on the surface.

  According to a third aspect of the present invention, in the first or second aspect, the image recording medium includes a substrate having an image recording surface capable of image recording by an image recording apparatus on the front surface side, and a substrate provided on the back surface side of the substrate. And a substrate holding part that can be held at a predetermined angle with respect to the mounting surface.

  The invention of claim 4 is an image recording medium package in which the image recording medium laminate according to claim 1 or 2 is housed in a moisture-proof bag capable of holding the laminated state of the image recording medium and packed in a box. It is characterized by.

  The invention according to claim 5 is a method of laminating a plurality of image recording media whose surfaces are image recording surfaces, wherein the lowermost image recording medium is such that the back side is the bottom and the surface is the top side. A plurality of image recording media are stacked in such a manner that the front surface and the front surface and the back surface and the back surface face each other sequentially.

  The invention of claim 6 is characterized in that, in claim 5, when the surface of the uppermost image recording medium faces upward, a protective sheet is laminated on the surface.

  According to a seventh aspect of the present invention, the image recording medium has a base having an image recording surface capable of image recording by an image recording apparatus on the front side, and a base provided on the back side of the base with respect to the mounting surface. And a substrate holding part that can be held at an angle of.

  The invention of claim 8 is a method for storing an image recording medium laminated by the method for laminating an image recording medium according to any one of claims 5 to 7, wherein the laminated state of the image recording medium can be maintained. It is housed in a moisture-proof bag and packed in a box.

  According to the first or fifth aspect of the invention, since the image recording media are sequentially laminated in a state where the image recording surfaces are aligned with each other, the image recording surfaces of the respective image recording media can be protected. Therefore, even if the substrate holding portion is processed on the back side of the base body as in the invention of claim 3 or 7, the processed surface can be prevented from touching the image recording surface, which is unnecessary. The image recording surface can be protected from scratches, dirt, peeling, and the like.

  In addition, when the surface of the uppermost image recording medium is upward as in the invention of claim 2 or 6, since the protective sheet is disposed on the surface, the surface side is always protected so as to cover the outside from the outside. can do.

  Further, by packing as in the invention of claim 4 or 8, the set state can be stored, transported and sold without breaking the set state.

  As shown in FIGS. 1 and 6, the image recording medium S includes a rectangular base 1 having an image recording surface P on the front side, on which an image can be recorded by an image recording apparatus, and both longitudinal ends of the base 1. A rectangular auxiliary portion (ear) 2 which is flush with the image recording surface P and attached as a protruding piece removable from the base 1, and the base 1 at a predetermined angle with respect to a mounting surface such as a table. As a substrate holding portion for holding the substrate 1 when standing, it is composed of four sets of leg portions 21A to 21D and leg support portions 22A to 22D provided on the back surface side of the substrate 1.

  The four sets of leg portions 21A to 21D and leg support portions 22A to 22D are provided corresponding to the four sides of the rectangular base 1, and the set of the first leg portion 21A and the leg support portion 22A, A set of the second leg portion 21B and the leg support portion 22B is arranged side by side along one long side (the lower side in FIG. 1C) of the base body 1, and the center line L1 in the length direction of the base body 1 With respect to each other. Further, the set of the third leg 21C and the leg support 22C and the set of the fourth leg 21D and the leg support 22D are the other long side of the base 1 (the upper side in FIG. 1C). Are arranged side by side and are in a line-symmetric relationship with respect to the center line L1 in the length direction of the base 1. The first leg portion 21A and leg support portion 22A and the fourth leg portion 21D and leg support portion 22D are each composed of one short side of the base 1 (the left side in FIG. 1C). Are arranged side by side and are in a line-symmetric relationship with respect to the center line L2 in the width direction of the substrate 1. Further, the set of the second leg portion 21B and the leg support portion 22B and the set of the third leg portion 21C and the leg support portion 22C are the other short side of the base 1 (the right side in FIG. 1C). Are arranged side by side and are in a line-symmetric relationship with respect to the center line L2 in the width direction of the substrate 1.

  Each of the leg portions 21A to 21D is provided integrally with the base body 1 via a connection portion (bending line) 24. By bending the connection portion 24, the base body 1 is placed at a predetermined angle with respect to the mounting surface. Demonstrate holding function. Further, the leg support portions 22A to 22D are provided integrally with the base body 1 via a connection portion (bending line) 26, and the leg portions 21A to 21D are inclined at a predetermined angle with respect to the base body 1 by bending the connection portion 26. Demonstrates the function of positioning.

  The leg support portions 22A to 22D include a first notch groove that can be engaged with the engagement groove 28 on the leg portions 21A to 21D side so as to support the base body 1 at the first position via the leg portions 21A to 21D. 27a and a second notch groove 27b that can be engaged with the engagement groove 28 on the side of the legs 21A to 21D is provided so as to support the base body 1 at the second position via the legs 21A to 21D. Yes. Here, the first position is a position where the base body 1 can be stably supported when the base body 1 is placed vertically on a table or the like, and the second position is a base body when the base body 1 is placed horizontally on a table or the like. 1 is a position where 1 can be stably supported.

  Next, the laminated structure of the image recording medium will be described with reference to FIG. Since the auxiliary portion 2 has the same laminated structure, only the laminated structure on the substrate 1 side will be described here as a representative.

  The base body 1 has a structure in which a first base body 11 on the front side and a second base body 12 on the back side are laminated and bonded in a symmetrical direction. The first substrate 11 and the second substrate 12 are composed of two layers having the same structure, and each of the two layers is composed of an upper image recording layer 16 and a lower support layer 17 that supports the upper image recording layer 16. . The image recording layer 16 is made of, for example, an ink jet paper in which an ink receiving layer 16a is laminated on a base material, and the support layer 17 is made of cardboard. The base body 1 has a structure in which four layers are laminated in this way, from the front surface side to the back surface side, the image recording layer 16 as the first layer, the first support layer 17 as the second layer, and the third layer. In addition, the second support layer 17 and the image recording layer 16 are arranged in the fourth layer.

  The reason why the first base body 11 and the second base body 12 are composed of a two-layer body having the same structure and are bonded in a symmetric orientation is to prevent the base body 1 from curling due to changes in humidity. The image recording layer 16 on the substrate 12 side (back surface side) 2 balances the front and back surfaces and functions as an anti-curl layer.

  The ink receiving layer 16a contains at least inorganic particles on the substrate. Examples of the substrate include plastic films such as polyethylene, polypropylene, and polyethylene terephthalate (PET), and sheets made of paper materials such as fine paper, coated paper, and laminated paper.

  As the inorganic particles, for example, porous amorphous silica, porous amorphous alumina, porous amorphous magnesium carbonate and the like are preferably used. The content of inorganic particles is preferably 30 to 90% by weight with respect to the dry weight of the ink receiving layer 16a.

  The ink receiving layer 16a contains a water-soluble polymer or emulsion such as polyvinyl alcohol, vinyl acetate, or acrylic as a binder for inorganic particles. The content of the binder is preferably 5 to 60 parts by weight with respect to 100 parts by weight of the porous inorganic particles. Further, the ink receiving layer 16a may be provided with a dye fixing agent, a fluorescent brightening agent, a fungicide, a preservative, a surfactant, a thickener, a pH adjuster, an antifoaming agent, a hardener, and a leveling as necessary. 1 type, or 2 or more types of various additives, such as an agent and a ultraviolet absorber, can be contained.

  The ink receiving layer 16a is formed by coating a coating liquid containing inorganic particles and a binder on the substrate by various methods such as a roll coating method, a rod bar coating method, and an air knife coating method. I can do it. The thickness of the ink receiving layer 16a at this time is preferably 10 to 60 μm from the viewpoint of ink absorbability and prevention of powder falling. The texture, texture, etc. of the ink receiving layer 16a are not particularly limited, and may be a matte tone, a high glossy tone that is mirror-finished by a casting method, or a semi-glossy tone.

  The four sets of leg portions 21A to 21D and the leg support portions 22A to 22D described above are provided on the second base 12 side, and cutting lines 23 and 24 having a predetermined contour are provided on a part of the second base 12. By being inserted, it is formed so that it can be caused according to the bending of the connecting portions 24 and 26. The cutting depth of the cutting lines 23 and 25 extends to the entire layer of the second base 12 but does not reach the first base 11 side.

  Further, the second base 12 is provided with an opening 29 adjacent to the leg portions 21A to 21D and the leg support portions 22A to 22D. These openings 29 are intended to facilitate work by inserting a finger or the like when the leg portions 21A to 21D and the leg support portions 22A to 22D are caused.

Next, the relationship between the auxiliary part 2 and the substrate 1 will be described.
The auxiliary portion 2 is connected to the short side portions at both ends in the longitudinal direction of the base body 1 so as to protrude by a necessary minimum dimension. As shown in FIG. 4, the auxiliary unit 2 is provided mainly for increasing the length of the image recording medium S when an image is recorded on the substrate 1 by the print head 51 of the image recording apparatus. That is, at the time of printing, the image recording medium S must be stably supported by the rollers 52 and 53. However, when printing to the edge of the base 1 is attempted, the image recording medium S ends there. , Support is likely to be unstable. Therefore, by providing the auxiliary unit 2, the length of the image recording medium S is extended to stabilize the support. With this configuration, it is possible to perform image recording (so-called borderless printing) up to the edge of the substrate 1. Further, since the auxiliary unit 2 is a part not intended for image recording, the image recording surface of the substrate 1 can be protected from being stained by handling the image recording medium S with the auxiliary unit 2.

  The layer structure of the auxiliary portion 2 is exactly the same as that of the base 1, and the surface of the auxiliary portion 2 and the image recording surface P of the base 1 are flush with each other so that they are not caught by the print head or the like. Further, in order to enable the auxiliary portion 2 to be easily separated from the base body 1, a linear continuous cutting portion 5, the auxiliary portion 2 and the back surface side are provided at the boundary between the auxiliary portion 2 and the first base body 11 on the front surface side. A straight perforated intermittent cut portion 6 is formed at the boundary with the second base 12. The non-cut portion of the intermittent cut portion 6 on the back surface side keeps the auxiliary portion 2 connected to the base 1. In this case, the length V1 from the longitudinal edge of the auxiliary portion 2 to the continuous cut portion 5 on the front surface side is shorter than the length V2 from the longitudinal edge of the auxiliary portion 2 to the intermittent cut portion 6 on the back surface side. Is set. And as shown in FIG.5 (b), in the part 7 between the continuous cutting | disconnection part 5 and the intermittent cutting | disconnection part 6 which shifted position, the adhesive agent of the quantity which the 2nd base | substrate 12 and the auxiliary | assistant part 2 are removable. It is adhered by.

  Further, at the end of the auxiliary portion 2 in the width direction (same as the width direction of the base body 1), a cutout 3 is provided in which the auxiliary portion 2 is eliminated. The notch 3 is used for the continuous cutting unit 5 or the intermittent cutting when the image recording is performed by a printer having a mechanical paper detector that detects the paper by tracing the upper surface or the lower surface of the image recording medium. The main purpose is to avoid the detection piece from being caught by the cutting part 6.

  Note that one end in the length direction of the continuous cutting part 5 formed in a straight line (an end part intersecting with the long side of the base 1) is used to round the corner of the base 1 when the auxiliary part 2 is cut off. It is curved in a small arc shape. On the other hand, since the intermittent cutting part 6 is in a position hidden from the front side as will be described later, both ends in the length direction end with a straight cut.

Next, how to use and operation of the image recording medium S having the above configuration will be described.
When an image is printed on the image recording medium S, it is recorded on the image recording surface P on the front side as shown in FIG. Next, as shown by an arrow A in FIG. 6, the auxiliary portions 2 at both ends that are no longer necessary are separated. At this time, as shown in FIG. 5, since the continuous cutting part 5 on the first base side 11 on the front surface is almost cut in advance, only the intermittent cutting part 6 on the second base 12 side on the back side is cut off. In this way, the auxiliary part 2 is removed.

  When cut by the intermittent cutting part 6 in this way, the cut surface becomes uneven, but the position of the intermittent cutting part 6 on the back surface side (second substrate 12 side) is the front surface side (first substrate 11 side). ) Is located closer to the center in the longitudinal direction of the base body 1 than the position of the continuous cutting part 5, the unevenness is hidden behind the first base body 11 from which the auxiliary part 2 is cut off. Here, since the edge of the 1st base | substrate 11 cut | disconnected by the continuous cutting part 5 is a beautiful cutting line by mechanical cutting, the edge of the base | substrate 1 after the auxiliary | assistant part 2 was cut | disconnected is beautiful. Only the cutting line can be seen from the front side, and the unfavorable portion of the appearance is not visible from the front side, and the aesthetic appearance when viewed from the front side is not impaired.

  Next, the direction to stand on the mounting surface of the table or the like is determined by the orientation of the image, and two pairs of leg portions 21A to 21D and leg support portions 22A to 22D along the lower side of the four sides of the base 1 are selected. Then, the corresponding two pairs of leg portions 21A to 21D and leg support portions 22A to 22D are caused in the directions of arrows B and C while bending the connection portions 24 and 26, respectively. FIG. 7 shows an example in which the base 1 is placed vertically, and shows a state in which two sets of leg portions 21A and 21D and leg support portions 22A and 22D along one short side are caused. When the legs 21A and 21D and the leg support portions 22A and 22D are caused, the openings 29 are provided adjacent to each other, so that the legs are easily caused.

  When the legs 21A and 21D and the leg support portions 22A and 22D are raised to some extent, as shown in FIG. 8, the notch grooves 27a of the leg support portions 22A and 22D are formed in the engagement grooves 28 of the leg portions 21A and 21D. 27b is engaged. In this case, since the first cutout groove 27a is set for vertical installation and the second cutout groove 27b is set for horizontal installation, the vertical cutout first cutout groove 27a is engaged with the legs 21A and 21D. Engage with the groove 28. By doing so, the engaging portion does not move, and the angles of the leg portions 21A and 21D can be fixed. Accordingly, the base body 1 can be stably held in a vertically placed posture at a predetermined angle by the leg portions 21A and 21D extending on the back surface side with one short side placed on the placement surface.

  When the base body 1 is placed vertically in the opposite direction, a pair of leg portions 21B and 21C and leg support portions 22B and 22C is selected, and the same assembly is performed and placed on the placement surface. When the base 1 is placed horizontally, as shown in FIG. 9, a pair of leg portions 21A, 21B and leg support portions 22A, 22B is selected according to the orientation, or the leg portions 21B, 21C and legs are selected. The pair of support portions 22B and 22C is selected or the same assembling is performed and placed on the placement surface. However, in the case of horizontal placement, the angle of the base body 1 is determined by engaging the second cutout grooves 27b of the leg support portions 22A to 22D and the engagement grooves 28 of the leg portions 21A to 21D.

  As described above, after the image is recorded on the image recording surface P of the base body 1, the base body 1 can be stood on a mounting surface such as a table using the leg portions 21A to 21D and the leg support portions 22A to 22D as they are. The image recording medium S can be used as a photo stand as it is. Therefore, there is no need to prepare a separate photo stand, and printed materials such as photographs can be easily displayed on the table.

  Further, by appropriately selecting and assembling the pairs of leg portions 21A to 21D and leg support portions 22A to 22D, the base body 1 can be erected in four directions, and the leg portions 21A to 21D are connected to the leg support portions 22A to 22A. Since positioning is performed at a predetermined angle by the 22D, the base body 1 can be stably held at a fixed angle regardless of who is assembled.

  Further, in this image recording medium S, the base body 1 is configured by bonding a first base body 11 having an image recording surface P and a second base body 12, and legs 21A to 21D and legs are provided on the second base body 12 side. Since the support portions 22A to 22D are provided, the first base 11 having the image recording surface P is subjected to processing such as cutting (cutting line) when the leg portions 21A to 21D and the leg support portions 22A to 22D are provided. This can be done without affecting the side, making the production easier. In addition, since the base body 1 is formed by bonding two sheets, the processing of providing the leg portions 21A to 21D and the leg support portions 22A to 22D on the back surface side, and the cutting portion 5 at the boundary between the auxiliary portion 2 and the base body 1 , 6 can be easily performed by shifting the positions of the front surface side and the back surface side.

Next, an optimum mode for storing, transporting, and selling the image recording medium S having the above configuration will be described.
Although the image recording medium S is formed of flat surfaces on both the front and back surfaces, the leg portions 21A to 21D and the leg support portions 22A to 22D are provided on the back surface side as described above so as to be caused. . Moreover, it comes out much thicker than normal print paper, and it also has the weight of each sheet. Accordingly, when the image recording surfaces (front surfaces) are laminated in the same direction as in normal printing paper, the portions where the leg portions 21A to 21D and the leg support portions 22A to 22D are formed hit the image recording surface P. In addition, the image recording surface P may be scratched or soiled, and the recording image quality may be deteriorated. In order to prevent this, a protective sheet can be sandwiched between each image recording medium S. However, this increases the number of unnecessary protective sheets used, leading to an increase in cost.

  Therefore, for example, when selling a set of a plurality of sheets, as shown in FIG. 10, the lowermost image recording medium S is arranged with the back side facing down and the top side facing up, and sequentially on the upper side, When a plurality of image recording media S are stacked with the front surface and the front surface and the back surface and the back surface facing each other, and the top surface of the image recording medium S faces upward, that is, when an odd number of image recording media S are stacked. The multi-sheet set SU1 is formed by laminating the protective sheet 30 on the surface of the uppermost image recording medium S. Then, as shown in FIG. 11, the image recording medium S is housed in a moisture-proof transparent bag 32 that can hold the stacked state of the image recording medium S, and packed in a box 33 to obtain a package product 35 of the image recording medium. By packing in this way, the image recording surface P can be protected and high-quality recording can be guaranteed.

  As shown in FIG. 12, when the even number of image recording media S are stacked to form the set SU2, the back surface of the uppermost image recording medium S faces upward, and thus it is not necessary to cover it with a protective sheet.

Next, a modification of the image recording medium S according to the present invention will be described with reference to FIG.
FIG. 13 is an overall configuration diagram of the image recording medium of the present modification, where (a) is a plan view seen from the front side, (b) is a side view, and (c) is a plan view seen from the back side.

  As shown in FIG. 13, this image recording medium S1 has a rectangular base 101 having an image recording surface P on the front side which can be recorded by an image recording device, and an image recording surface P at both longitudinal ends of the base 101. A rectangular auxiliary portion (ear) 102 that is flush and attached as a protruding piece that can be detached from the base 101, and the base 101 when the base 1 is stood at a predetermined angle with respect to a mounting surface such as a table. As a base holding part to be held, it is composed of four sets of leg parts 121A to 121D and leg support parts 122A to 122D provided on the back side of the base body 101.

  Four sets of leg portions 121A to 121D and leg support portions 122A to 122D are provided corresponding to the four sides of the rectangular base body 101, and a set of the first leg portion 121A and the leg support portion 122A, The set of the second leg portion 121B and the leg support portion 122B is arranged side by side along one long side (the lower side in FIG. 1C) of the base 101, and the center line L1 in the length direction of the base 101. With respect to each other. Further, the set of the third leg 121C and the leg support 122C and the set of the fourth leg 121D and the leg support 122D are the other long side of the base 101 (the upper side in FIG. 1C). Are arranged side by side and are in a line-symmetric relationship with respect to the center line L1 in the length direction of the base 101. Also, the first leg 121A and leg support 122A set and the fourth leg 121D and leg support 122D set are one short side of the base 101 (the left side in FIG. 1C). Are arranged side by side and are in a line-symmetric relationship with respect to the center line L2 in the width direction of the base body 101. Further, the set of the second leg 121B and the leg support 122B and the set of the third leg 121C and the leg support 122C are the other short side of the base 101 (the right side in FIG. 1C). Are arranged side by side and are in a line-symmetric relationship with respect to the center line L2 in the width direction of the base body 101.

  Each of the leg portions 121A to 121D is provided integrally with the base body 101 via a connection portion (bending line) 124. By bending the connection portion 124, the base body 101 is placed at a predetermined angle with respect to the mounting surface. Demonstrate holding function. Further, the leg support portions 122A to 122D are provided integrally with the base body 101 via a connection portion (bending line) 126, and the leg portions 121A to 121D are inclined at a predetermined angle with respect to the base body 101 by bending the connection portion 126. Demonstrates the function of positioning.

The leg support portions 122A to 122D have notch grooves 127 that can be engaged with the engagement grooves 128 on the leg portions 121A to 121D side so as to support the base 101 in the first position via the leg portions 121A to 121D. Is provided.
Other layer structures and functions of the image recording medium S1 are the same as those of the image recording medium S described above.

  In this modification, when an image is recorded on the image recording surface P of the image recording medium S1 and the base 101 of the image recording medium S1 is arranged vertically, the auxiliary portions 102 and 102 are removed, and the leg portions 121A, The notch grooves 127 and 127 of the leg support portions 122A and 122D are engaged with the engagement grooves 128 and 128 of the leg portions 121A and 121D by causing the 121D and the leg support portions 122A and 122D to some extent. By doing so, the engaging portion can be prevented from moving, and the angles of the leg portions 121A and 121D can be fixed. Accordingly, the base body 1 can be stably held in a vertical position at a predetermined angle by the leg portions 121A and 121D extending on the back surface side with one short side placed on the placement surface.

  Further, when an image is recorded on the image recording surface P of the image recording medium S1 and the base 101 of the image recording medium S1 is disposed horizontally, the auxiliary portions 102 and 102 are removed, and the leg portions 121A and 121B and the leg portions are removed. The support portions 122A and 122B are raised to some extent, and the notch grooves 127 and 127 of the leg support portions 122A and 122B are engaged with the engagement grooves 128 and 128 of the leg portions 121A and 121B. By doing so, the engaging portion does not move, and the angles of the leg portions 121A and 121B can be fixed. Therefore, the base 1 can be stably held in a horizontal posture at a predetermined angle by the leg portions 121A and 121B extended on the back surface side with one short side placed on the placement surface.

  Similar to the image recording medium S described above, even if the leg support portions 122A to 122D are each provided with only one notch groove 127 as in the image recording medium S1 of the present modification described above. It is possible to achieve an effect.
