Description

  The present invention relates to a jig for holding a recording sheet, and more particularly to a jig suitable for drying a recording sheet printed using water-based ink. The present invention also relates to a unit including a recording sheet and a jig.

  In recent years, various types of inkjet recording media for inkjet recording have been sold. An ink jet recording apparatus performs ink jet recording on this type of recording medium, but there are many limited recording media suitable for the fixing characteristics of the ink itself used. For this reason, in Patent Document 1, the next recording medium continuously recorded is temporarily held in the upper space with respect to the recording medium previously recorded, and ink fixing of the recording medium previously recorded is performed. An apparatus for laminating after waiting to complete is disclosed. This apparatus has a complicated configuration for satisfying this function, and causes an increase in the size of the apparatus.

On the other hand, inkjet postcards that have come to be used in Japan Post are not optimized for the ink characteristics of the inkjet recording apparatus, and therefore are not yet printed on postcards printed by the inkjet recording method. In order to dry the ink in the dry state, the ink in the undried state is dried one by one on a desk or the like. As a method for easily drying this postcard, Patent Document 2 uses a sheet material provided with at least two rows of comb-shaped support pieces formed by making a large number of cuts in substantially the same direction. A method is disclosed in which an inkjet recording sheet printed on is leaned against and dried. In this method, it is described that a large number of printed materials are simultaneously dried by being hung on two rows of comb-shaped support pieces, and it is not necessary to secure a very large space during the drying.
JP-A 63-239073 JP 2003-276777 A

  By the way, in ink jet recording, apparatuses for recording on both sides of a recording medium have been provided on the market. However, since inkjet recording sheets printed on both sides differ depending on various recording medium characteristics, fixing after recording can be a problem. When the present inventors examined, after printing one side, it dried, and also the method which dried the one side which turned upside down was printed and dried, or the method of leaving it on a desk surface and drying after double-sided printing etc. As a result, there was a problem that it was impossible to obtain the same print quality on both sides even though it was an inkjet recording sheet for double-sided printing. Also, the method of hanging on a laundry hanger and drying causes problems such as scratches on the image area of the inkjet recording sheet, particularly on the center side. In addition, when the printing surfaces of recording sheets that have been simply double-sided ink jet recorded are left to be stacked before they are sufficiently dried, the images are transferred to each other and appear to be white and dull (hereinafter referred to as white). The image quality was degraded. In this way, the phenomenon of mutual image transfer is caused by the fact that an ink receiving layer is provided on a non-absorbing substrate that does not absorb water, such as an inkjet recording medium having a glossy surface and PET film or resin-coated paper. This was noticeable when an ink jet recording sheet was loaded. This white haze is considered to appear white and cloudy due to the refraction and scattering of light due to the occurrence of dry and non-dry portions in the ink receiving layer. Normally, the amount of ink applied varies depending on the location in the recording area, so when the print surfaces are left on top of each other, the dry state of the ink varies depending on the location, resulting in a white haze, which results in uneven image density. It is estimated that the image quality will be degraded.

  Then, when the present inventors verified the invention disclosed in Patent Document 2, the following problems were found. That is, after ink-jet recording (single-sided or double-sided recording) using an ink-jet recording sheet instead of a postcard, it is placed on both sides of two rows of comb-shaped support pieces (recording medium support jig). The ink dried state was different between the contacting part and the non-contacting part, and the image quality was lowered. In addition, because this support piece comes into contact with the printing surface, scratches occur in the image area, or it is left to leave it to its own weight, so when used in a high temperature and high humidity environment, The stiffness (rigidity) of the paper is lowered by the influence of humidity, the recording medium is not straight, and problems such as deterioration in quality such as deformation as a recorded matter occur.

  Therefore, the present invention has a first problem that the printed recording medium is different in the dry state between the portion in contact with the jig and the portion not in contact with the jig, resulting in a decrease in image quality due to density unevenness, a recorded image of the printed recording medium The second problem of causing scratches due to contact with the jig, particularly the center side, and the stiffness (rigidity) of the paper in a high-temperature, high-humidity environment is reduced by the influence of humidity. Solves the third problem that the recorded medium cannot be held straight and the recorded material is bent, and the deterioration of the image at the end of the recorded medium on which the entire recording medium is recorded (so-called borderless printing). An object of the present invention is to provide an invention capable of solving at least one of the fourth problems. The above problems are common to drying recorded sheets other than ink jet recording sheets recorded on one or both sides.

  Therefore, the present invention is preferably used for a method of drying a recorded recording medium with essentially no deterioration in the state of a recorded image (preferably without causing unevenness of drying and scratches), and to be used for it. The purpose is to provide jigs. Another object of the present invention is to provide a unit having a recording medium and a jig suitable for drying the recorded recording medium. Further objects of the present invention will be understood from the following description.

The first invention of the present invention solves the first problem or the second problem among the above problems,
A jig having at least a pair of holders capable of detachably holding both ends of the recording sheet, and a connecting portion for connecting the pair of holders,
The recording sheet forms a curved surface in a state where the recording sheet is held by the pair of holders, and the recording sheet is used as the pair of holders by utilizing the restoring force of the recording sheet having the curved surface. It is a jig characterized by being held.

Further, the second invention of the present invention solves the first and second problems among the above-mentioned problems.
A recording sheet drying method comprising mounting a recording sheet on a pair of holders included in the jig and drying the recording sheet.

The third invention of the present invention solves the first, second, and third problems among the above-mentioned problems.
A unit comprising the jig and a recording sheet. In this case, it includes a statement that the recording sheet is used so as to form a curved surface on a pair of holders as a usage manual or a printed description. Further, the end of the recording sheet and the holding It is preferably suggested or disclosed that the tool is in point contact or line contact.

  In addition, the fourth invention of the present invention solves at least the fourth problem among the above-mentioned problems, and in a state where the recording sheet is held by the pair of holders, an end of the recording sheet and the holder Is a point contact or a line contact.

  Other aspects of the invention will be understood from the description of the implementation.

  Each invention of the present invention solves the above-mentioned problems and exhibits a corresponding effect, but a method for easily drying a recording sheet without causing uneven drying and rubbing scratches of a comprehensively required image area, and And a jig suitably used therefor. Moreover, a unit having a recording sheet and a jig suitable for drying the sheet can be provided.

  While developing the ink jet recording sheet suitable for the ink jet recording method capable of duplex printing, the present inventors also studied the drying method so that the ink jet recording sheet is in a state of forming a curved surface. And, by using a jig capable of holding each end portion of the inkjet recording sheet by utilizing its restoring force, it was found that it can be easily dried without causing uneven drying and scratches, and the present invention Has been completed.

  First, the jig of the present invention and the recording sheet drying method using the same will be described.

  The jig of the present invention has at least one pair of holders capable of detachably holding both ends of the recording sheet, and a connecting portion for connecting the pair of holders, and the pair of holdings. The recording sheet forms a curved surface in a state where the recording sheet is held by a tool, and the recording sheet is held by the pair of holding tools by using the restoring force of the recording sheet having the curved surface. It is what has. The recording sheet drying method of the present invention is to attach the recording sheet to a pair of holders included in the jig and dry the recording sheet.

  FIG. 2 is a perspective view showing an example of a specific structure of the jig of the present invention, and FIGS. 3 and 4 are front views of the jig when viewed from the A direction and the B direction in FIG. 2, respectively. The jig 11 is composed of a pair of holders 22 composed of two projecting pieces 31 and a connecting portion 21 that connects them. The state when the recording sheet 91 is set on the jig 11 is shown in FIG. 9 as a front view when the jig 11 is viewed from the direction B in FIG. In this manner, the both end portions of the recording sheet 91 are held by the protruding pieces 31 that form a pair of holders. At this time, the recording sheet 91 is in a state where a curved surface is formed. The recording sheet 91 tries to return to a flat surface, but the projecting piece 31 forming the holder exhibits the function of a stopper, so that the recording sheet 91 is held while maintaining the curved surface state by its own restoring force.

  FIG. 17 shows a perspective view of a state where the jig 11 is set on the recording sheet 91 and placed on a desk or the like. Since the recording sheet 91 is held in a state where a curved surface is formed, it can be easily set up. At this time, the jig 11 is supported by the restoring force of the recording sheet 91 and does not fall off naturally. When it is desired to remove, the recording sheet 91 can be easily removed from the jig 11 without being scratched by curving the recording sheet 91 slightly.

  As described above, according to the jig having the configuration of the present invention, the recording sheet can be brought into a contact state only at the end portion thereof. That is, the recording sheet can be dried easily and uniformly by drying the recording sheet mounted on a pair of holders included in the jig. As the state at the time of drying, as shown in FIG. 17, it may stand on a desk or the like, or it may be placed on a desk or the like with the jig down, or the jig may be hung on a laundry hanger or the like.

Here, FIG. 11 shows an enlarged view of a contact portion between the protruding piece 31 forming the holder and the recording sheet 91 in a state where the jig 11 is set on the recording sheet 91. At this time, the angle Φ ₁ formed by the recording sheet 91 and the connecting portion 21 is smaller than the angle Φ ₂ formed by the ejection piece 31 and the connecting portion 21 forming the holder, and the end of the recording sheet and the holder Is preferably in a point contact or line contact state. If it will be in this state, it will be in the state which the printing surface of a recording sheet and a holder do not contact at all, and even in the case of borderless printing, it becomes possible to dry suitably. Further, from the viewpoint of realizing a good holding force, Φ ₂ is preferably 90 ° or less.

  The jig of the present invention can be used for drying various recording sheets such as inkjet recording sheets and photographic recording sheets. Especially, it can use preferably for drying of the inkjet recording sheet with many problems in the drying method, and can use it especially preferably for drying of the inkjet recording sheet which can perform double-sided printing.

  There are no particular restrictions on the inkjet recording sheet, and the A series size, B series size, letter size, postcard size, and the L size, 2L size, 4 × 6 size, and six cuts that are familiar in silver halide photography, The present invention can be applied to an ink jet recording sheet of any size, such as four cuts. The size and shape of the jig may be adjusted according to the size of the recording sheet. That is, the length of the long side of the recording sheet must be shorter than the length between the jig holders. More preferably, when the length of the long side of the recording sheet is B and the length between the jig holders is L (see FIG. 2), 2B / 3 ≦ L ≦ 9B / 10 is preferable.

  There are no restrictions on the type of ink-jet recording sheet, but considering the high resilience of the ink-jet recording sheet and the difficulty of curling after drying, the ink-jet recording sheet has a base material for resin-coated paper. It is preferable to apply to a recording sheet.

  The recording sheet preferably has a certain degree of rigidity (roughness) in order to develop a restoring force while being held in a curved shape. As the rigidity, J. et al. TAPPI No. 40, preferably 300 to 5000 mgf, more preferably 300 to 4000 mgf. In the case of an ink jet recording sheet, it is particularly preferably 500 to 3000 mgf from the viewpoint of transportability and restoring force in an ink jet printer. In addition, an appropriate thickness is important for realizing a high restoring force. For example, in the case of an inkjet recording sheet, the thickness is preferably 100 to 500 μm. In consideration of the transportability and the restoring force of the ink jet printer, and the curling of the curl after drying is difficult, 180 to 350 μm is more preferable. Especially preferably, it is 200-300 micrometers.

  The material of the jig is art paper, glossy paper, bond paper, recycled paper, baryta paper, cast coated paper, coated cardboard, corrugated paper, paperboard, non-wood paper, synthetic paper, etc .; polyethylene terephthalate, diacetate, Use resin such as triacetate, celluloid, polycarbonate, polyimide, polyacrylate, polyethylene, polypropylene, ABS; wood such as veneer, straw, cedar; metal such as aluminum, iron, copper, brass, stainless steel; rubber elastic body be able to.

  Also, a jig made of an absorbent member that easily absorbs water or a jig made of a non-absorbent member that hardly absorbs water can be used, but from an absorbent member that hardly causes uneven drying at the edge of the recording sheet. It is preferable to use the following jig. However, even in the case of a non-absorbing member, drying unevenness at the end of the recording sheet is hardly caused by subjecting the surface to a hydrophilic treatment.

  The surface of the jig may be a smooth surface, an uneven surface, or transparent, translucent, or opaque. Two or more of these materials may be bonded together. Furthermore, various decorations and coloring may be applied as part of the interior.

  Since it is necessary to hold the recording sheet in a curved shape, it is preferable to use thick paper such as coated cardboard or paperboard in consideration of strength and cost when the material of the jig is paper. The thickness is preferably 0.2 to 2 mm, more preferably 0.3 to 1 mm, from the viewpoint of the strength of the jig, ease of processing, and cost. In the case of other materials, since the strength is higher than that of paper, there is no particular limitation as long as the recording sheet can be maintained in a curved shape. For example, if it is used as a part of an interior, it is preferable that it is quite thick and decorated as such.

  When the jig is made of a material that cannot be bent easily, a jig having a predetermined shape capable of exhibiting the function of the present invention may be produced by a method such as mold integral molding or melt molding. The shape of the jig at this time can be arbitrarily set so that the function of the present invention can be exhibited. That is, the shape of the connecting portion is not limited to a flat shape as shown in FIG. 2, and may be, for example, a prismatic shape or a cylindrical shape. Further, the shape of the holder is not limited to a shape obtained by bending a flat surface as shown in FIG. 2, and may be, for example, a prismatic shape, a cylindrical shape, or a spherical shape. Furthermore, in consideration of the interior, it may be shaped like a character.

  In the case of a jig that can be bent easily, such as paper, plastic such as polystyrene or ABS, it may be a jig having a predetermined shape from the beginning as described above. For example, it can be assembled three-dimensionally as a flat jig. It can also be a structure.

A top view of an example of a planar jig capable of forming the jig shown in FIG. 2 is shown in FIG. The jig shown in FIG. 1 is composed of a planar member 41, and has bent portions 44 separated by cuts 42 and folding portions 43 at four corners. A protruding piece can be formed by three-dimensionally bending the bent portion 44 along the folding portion 43. Such a jig can be easily made into a three-dimensional jig, for example, by making it with cardboard such as coated cardboard or paperboard. The bending angle θ ₁ shown in FIG. 3 can be arbitrarily selected from the range of 0 ° <θ ₁ <180 ° as long as the function of the present invention can be exhibited, but the recording sheet holding force, ease of reuse, etc. Considering practical aspects, 30 ° ≦ θ ₁ ≦ 120 ° is preferable. In the example of FIG. 2, two protruding pieces are used as one holder, but the function of the present invention can be exhibited even at one place. That is, when the bending direction of the bent portion of the jig of FIG. 1 is reversed, the jig can hold two recording sheets on the front and back surfaces.

FIG. 5 shows an enlarged view of the vicinity of the left end of the planar jig of FIG. In this example, the cut 42 is perpendicular to the end of the planar member (θ ₂ = 90 ° in FIG. 5), but this angle can be arbitrarily set within a range in which the function of the present invention can be exhibited. For example, as shown in FIG. 6, it can also be set as the cut | notch 42 which becomes diagonal ((theta) ₂ > 90 degree in FIG. 6) with respect to the edge part of a planar member. The oblique direction improves the retention of the inkjet recording sheet. In consideration of practical use, 90 ° ≦ θ ₂ ≦ 150 ° is preferable. The position and length of the cut can be arbitrarily set within a range in which the function of the present invention can be exhibited. The angle, position, and length of the cut may be the same or different for each cut.

  In addition, as shown in FIG. 10, it is preferable to provide an uncut portion 45 in the middle of the cut 42. By providing the uncut portion 45, the bent portion 44 is less likely to be broken before use. The uncut part 45 can also be provided in one place in one notch, and can also be provided in two or more places.

  In addition, as shown in FIG. 7, it is also possible to form cuts 42 at two locations from the same end portion at the four corners of the planar member 41 and provide bent portions 44 at two locations. In this case, for example, a three-dimensional shape as shown in FIG. 12 can be obtained by bending the two bent portions 44 in opposite directions. This jig 11 can hold two recording sheets simultaneously (front view with the recording sheets set: FIG. 13), and the drying efficiency is improved. In the case of this jig, when two recording sheets of different sizes are held at the same time, it can be handled by changing the folding direction (front view with the recording sheet set: FIG. 15). In addition, the cuts 42 may be obliquely formed (top view: FIG. 8, front view with recording sheet set: FIGS. 14 and 16).

  As described above, a jig for converting a planar state into a three-dimensional state is used in a three-dimensional state, but one that can be returned to a planar state is convenient. Any jig that can reversibly change to either a three-dimensional state or a planar state can be easily placed in a recording sheet package.

  Furthermore, as shown in FIG. 18, it can also be set as the form of the master sheet | seat 50 which can cut out some plane members 41. FIG. In this case, it is preferable that the periphery of the jig is processed by the cut portion and the uncut portion so that each flat member 41 can be easily separated. In FIG. 18, a configuration in which four planar members 41 are arranged is shown as an example. However, the number of the planar members 41 can be adjusted as appropriate depending on the strength, the thickness of the recording sheet to be held, the rigidity, and the like. The angle, position, length, etc. of the cut can be set as appropriate.

  Since the jig as described above can be suitably used for drying a recording sheet, a unit including the recording sheet and the jig is preferable. In particular, a jig that forms a protruding piece by three-dimensionally bending a part of a planar member can be easily placed in a recording sheet package, and thus is suitable for use as a unit. At this time, it is preferable that the length of the long side of the planar member serving as a jig is equal to or less than the length of the long side of the inkjet recording sheet. In this way, the jig can be easily placed in the recording sheet package without increasing the overall size of the unit. In this case, it includes a statement that the recording sheet is used so as to form a curved surface on a pair of holders as a usage manual or a printed description. Further, the end of the recording sheet and the holding It is preferably suggested or disclosed that the tool is in point contact or line contact.

  As another embodiment, a protruding piece serving as the holder can be formed directly on the printer. The position where the protruding piece serving as the holder is formed may be on the upper lid of the printer (FIG. 19) or on the side surface (FIG. 20). It is preferable that the projecting piece has a foldable form, so that it can be folded after use. Considering the interior, the holder can be shaped like a character. In addition, it is also preferable that the shape of the jig is punched on the surface of the printer so that it can be attached and detached using a magnet or the like.

  Hereinafter, the present invention will be described in more detail with reference to examples.
