Description

  The present invention relates to a disk-shaped recording medium, an edge seal, and an edge seal sticking device.

Conventionally, as a technique for printing on the label surface of this type of disk-shaped recording medium, one using an inkjet printer is known (for example, see Patent Document 1).
According to this configuration, a CD (compact disc) in which an ink receiving layer having an ink fixing property is formed on the label surface in advance is placed on the CD tray, and the CD tray is loaded by the paper feeding means in the same manner as the printing paper. It was possible to print by scanning. Since the CD tray and the ink jet printer are provided with a guide portion for positioning both in the main scanning direction, a reflection portion, a light emitting portion, a sensor and the like for positioning in the sub scanning direction, the CD tray and the ink jet printer are positioned at appropriate positions on the CD label surface. It was possible to print by discharging ink.
Japanese Patent Laid-Open No. 2003-112458

In the above-described label surface printing, it is difficult to completely eliminate the positional deviation no matter how the positioning accuracy between the CD tray and the ink jet printer is improved. Therefore, there is a problem that the ink protrudes from the ink receiving layer and contaminates the ink jet printer and the reproducing apparatus. Further, for the same reason, it is not possible to perform printing that requires high positioning accuracy such as printing without leaving a margin on the outer edge of the ink receiving layer. In addition, even when printing is performed so as to leave a margin, if the printed area is shifted with respect to the ink receiving layer, the margin width becomes non-uniform and the appearance is poor.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a disc-shaped recording medium, a border seal, and a border seal pasting device that do not contaminate the printing apparatus and enable printing without blank spaces.

Means for Solving the Problems and Effects of the Invention

  In order to solve the above-described problems, in the invention according to claim 1, the label surface of the disc-shaped recording medium has a print area having ink fixing properties, and ink is ejected to the print area. Print. A border seal that has ink fixing properties and can be peeled off is attached to a non-printing area adjacent to the printing area.

  Since both the printing area and the border seal have ink fixing properties, even if printing is performed so as to protrude on the border seal, the ejected ink is held on the label surface, and the print image is printed. Can be formed. In addition, the ejected ink is not repelled or scattered, and the printing apparatus, the recording / reproducing apparatus, and the like are not contaminated. When printing is performed so as to protrude from the printing area onto the border seal, printing can be performed up to the end of the printing area, and printing can be performed without a margin in the printing area. Since the border seal that protrudes and discharges ink can be peeled off after printing, the ink that protrudes and discharged can be removed together with the border seal. Therefore, finally, it is possible to leave only a printed image formed without any margin in the printing area on the label surface. Thereby, a good-looking label surface can be formed.

  According to a second aspect of the present invention, after an ink receiving layer having ink fixing properties is previously formed in the printing area, the border seal is attached so as to be adjacent to the ink receiving layer. That is, it is possible to provide the print area with ink fixing properties, and the border seal is attached to the non-print area. By forming the ink receiving layer in the printing area in advance, the non-printing area to which the border seal is attached can be easily specified.

  According to a third aspect of the present invention, the ink receiving layer is formed so as to protrude from the printing region onto the bordering seal after the bordering seal is previously applied to the non-printing region. The ink receiving layer is also formed in the non-printing area, but can be finally removed together with the border seal. In this way, the ink receiving layer that protrudes and the ink that protrudes and are ejected can be removed by the same edging seal. Therefore, the ink receiving layer and the outer edge of the printed image can be always matched.

  According to a fourth aspect of the present invention, the border seal is formed in a frame shape and is attached to a non-printing area adjacent to the printing area. Further, the frame-shaped edging seal is divided by cutting. By doing so, it becomes possible to pull the frame-shaped edging seal linearly from the notch and to peel it off. Therefore, the peeling work can be simplified.

  Furthermore, in the invention concerning Claim 5, the said border seal | sticker is formed by forming the layer which has ink fixability on the base material which has flexibility. In other words, the border seal has ink fixing properties and is flexible to some extent, so that it does not deform and break when it is peeled off. Therefore, it is possible to easily peel off the border seal.

  Further, in the invention according to claim 6, the invention is specified on the assumption that printing is performed on the disk-shaped recording medium of claim 1 and the border seal is peeled off. Further, claim 7 specifies the invention as an edge seal used for the disk-shaped recording medium of claim 1. Further, it is possible to make the configurations of the second to fifth aspects correspond to the disc-shaped recording medium of the sixth aspect and the edging seal of the seventh aspect.

  Furthermore, the invention according to claim 8 provides an edging seal attaching device for accurately attaching the edging seal to the disc-shaped recording medium. In the border seal pasting apparatus, the disc-shaped recording medium and the border seal can be positioned by providing positioning means for the disc-shaped recording medium and positioning means for the border seal. Therefore, the border seal can be attached to the disc-shaped recording medium at an accurate position.

Hereinafter, embodiments of the present invention will be described in the following order.

(2) Second embodiment:
(3) Third embodiment:
(4) Summary:

(1) First embodiment:
FIG. 1 shows an oblique view of a writable compact disc (CD-R: Compact Disk Recordable) as a disc-shaped storage medium according to the first embodiment of the present invention. In the figure, the CD-R 10 is formed in a disk shape, and a circular holding hole 14 penetrating the center is formed. In the figure, the surface oriented downward is a recording surface 10b, and music or the like is recorded as digital data. A device that records and reproduces a CD-R10 such as a CD recorder or a CD player rotates the CD-R10 while holding the CD-R10 in the holding hole 14, and optically writes the digital data from the recording surface 10b. And reading.

  In the figure, the surface oriented upward is a label surface 10a, and various characters, designs, etc. can be printed so that the CD-R 10 can be visually identified on the label surface 10a. ing. An ink receiving layer 11 is formed on the label surface 10a of the CD-R 10, and a predetermined resin or the like is applied to the label surface 10a and cured to fix the ink used for printing to the ink receiving layer 11. It is possible to do. Examples of the material of the ink receiving layer 11 include a material obtained by adding silica or alumina to a water-soluble polymer as a filler in an aqueous medium as disclosed in JP-A-6-60432, or JP-A-7-44888. It is possible to use a material having a radiation curable receptivity including a water-soluble monomer, a hydrophobic polymer, and an inorganic filler. Of course, the ink receiving layer 11 is not limited to the above example as long as it can fix the ink. Further, the ink to be fixed is not limited to the dye ink that is absorbed and fixed by the receiving layer 11, and may be a pigment ink.

  The ink receiving layer 11 is formed in an annular shape on the recording surface 10b. The inner diameter (38mm) is larger than the diameter (15mm) of the holding hole 14, and the outer diameter (112mm) is larger than the outer diameter (120mm) of the CD-R10. It is getting smaller. An annular inner edge label 13 is affixed inside the same inner diameter on the recording surface 10b, and an annular outer edge label 12 is affixed outside the outer diameter. Each of the outer edge label 12 and the inner edge label 13 has a width of 2 mm. The sizes of the outer edge label 12 and the inner edge label 13 can be changed as appropriate, and are not limited to the sizes described above. The CD-R 10 is merely shown as an example of a disk-shaped recording medium, and may be a disk-shaped recording medium of another standard such as a DVD (Digital Versatile Disk) or an LD (Laser Disk). Of course, the present invention is not limited to a circular disk-shaped recording medium. Needless to say, the shape of the border label conforms to the standard of the disk-shaped recording medium.

  FIG. 2 shows a cross section of the CD-R 10. In the figure, an inner edge label 13 is attached to the inner diameter of the ink receiving layer 11 from the inside, and an outer edge label 12 is attached to the outer diameter of the ink receiving layer 11 from the outside. The inner border label 13 has a three-layer structure, and is composed of an ink receiving layer 12a, a substrate 12b, and an adhesive layer 12c from the upper layer. The ink receiving layer 12a of the inner edge label 13 has ink fixing properties like the ink receiving layer 11 described above. The base material 12b is flexible and needs only to have a certain degree of strength. For example, the base material 12b can be formed of general polypropylene. The adhesive layer 12c is formed of an adhesive having high hardness so that when the inner rim label 13 is peeled off from the CD-R 10, it is broken and a part thereof does not remain on the CD-R 10. As a material of the adhesive layer 12c, for example, a general acrylic pressure-sensitive adhesive can be used.

  In this way, the inner edge label 13 can be easily peeled off from the CD-R 10. That is, since the base material 12b has flexibility and strength, the inner edge label 13 can be peeled off without breaking. Further, the adhesive layer 12c does not remain on the CD-R 10 after being peeled off, and the appearance does not deteriorate. Since the outer edge label 12 has the same configuration as the inner edge label 13, it can be easily peeled off in the same manner.

  On the other hand, the thickness of the ink receiving layer 11 is about 100 μm or less, and the outer edge label 12 and the inner edge label 13 are formed to be approximately equal to this thickness. Therefore, the outer edge label 12 and the inner edge label 13 protrude above the ink receiving layer 11 and do not hinder the recording / reproducing of the CD-R 10. Further, the outer edge label 12, the inner edge label 13, and the ink receiving layer 11 have an annular shape, and the center coincides with the center of the CD-R 10. Therefore, the center of gravity is stable and the CD-R 10 can be rotationally driven stably. That is, the CD-R 10 is formed so as not to interfere with recording / reproduction even when the outer edge label 12 and the inner edge label 13 are still attached.

  Since the ink can be fixed on the outer edge label 12, the inner edge label 13, and the surface of the ink receiving layer 11, the ink is formed on the outer edge label 12, the inner edge label 13, and the ink receiving layer 11. Can be discharged. That is, since the ejected ink can be fixed, the ejected ink does not scatter or bleed, and printed images such as various characters and designs can be held. In addition, since a design or the like can be expressed on the label surface 10a, the CD-R 10 can be visually identified. Various methods are conceivable for printing by ejecting ink onto the label surface 10a. Here, an example in which printing is performed using a general inkjet printer will be described.

  FIG. 3 shows the inkjet printer 40 as viewed from an oblique direction. The printer 40 includes a print head (not shown) provided with an ink discharge unit inside, and the print head can perform printing by sub-scanning the recording medium in the depth direction while performing main scanning in the width direction. It has become. In the figure, a printer 40 is provided with a disk tray 41, and the disk tray 41 can be sub-scanned by a paper feed mechanism. The disc tray 41 includes a circular concave portion 41a on which the CD-R 10 can be positioned and placed. Further, a part of the disc tray 41 is formed with a position detection unit 41b having a higher light reflectance than the other parts.

  The printer 40 can detect the reflected light from the position detection unit 41b by a light receiving sensor (not shown) provided inside while the disk tray 41 is sub-scanned. Accordingly, the disk tray 41 can be positioned in the sub-scanning direction. Further, since the disc tray 41 is sandwiched between the pair of guide portions 40a and 40b from the outside in the width direction, positioning in the main scanning direction is also possible. Of course, if the disk tray 41 is positioned, the CD-R 10 placed in the circular recess 41a is also positioned. The printer 40 is connected to a personal computer and can execute printing by cooperating with the PC.

  FIG. 4 is a block diagram showing the internal configuration of the personal computer 50 connected to the printer 40. The printer 40 is controlled by a printer driver installed in the computer 50 to execute printing, and the printer driver causes the computer 50 to function as a print control device. Specifically, a printer driver (PRTDRV) 52, an input device driver (DRV) 56, and a display driver (DRV) 55 are incorporated in the OS 51. The display DRV 55 is a driver that controls display of image data and the like on the display 60, and the input device DRV 56 receives code signals from the keyboard 71 and the mouse 72 input via the serial communication I / O 57a and receives predetermined inputs. Accept the operation.

  The APL 53 is an application program that can execute retouching of a color image, and the user operates the input device for operation under the execution of the APL 53. For example, the image data 54a stored in the hard disk (HDD) 54 indicates A print instruction can be issued by retouching the image. When a print instruction is issued by the APL 53, the PRTDRV 52 is driven, and the image data conversion module 52a performs processing such as size conversion, color conversion, and halftone processing, and print data that can be executed by the printer 40 is generated. The printer 40 receives print data via the USB I / O 57b, and drives the paper feed mechanism, print head, and the like based on the data to realize printing.

In this embodiment, software for printing on the CD-R 10 is installed in the computer 50 as one of the APLs 53.
FIG. 5 shows an example of the area designation screen output to the display 60 by the software. In the figure, an image composed of a landscape image and characters is designated as an image to be printed, and an image area C to be actually printed is previewed on the same screen. The image area C can be moved up and down and left and right by operating the mouse 72, and the user can move the image area C to a desired position while looking at the display 60. In addition, boxes A and B for inputting an inner diameter and an outer diameter indicating a desired printing area are provided on the same screen, and the user can designate a desired printing area by operating the keyboard 71. ing. Since the size of the image area C is changed in accordance with the size of the designated printing area, the user can grasp the actual printing state.

  When a user designates a print area using the keyboard 71, it is possible to input a desired print area. Here, when printing is desired on the entire surface of the ink receiving layer 11, the inner diameter of the ink receiving layer 11 and What inputs an outer diameter is demonstrated. The inner diameter and outer diameter of the ink receiving layer 11 are described in the packaging of the CD-R 10 and the like, and the user inputs the inner diameter and the outer diameter as desired printing areas based on this. Of course, the user can also measure the inner and outer diameters by himself. In this embodiment, since the outer diameter of the ink receiving layer 11 is 112 mm and the inner diameter is 38 mm, it is assumed that the respective values are input. That is, the upper surface of the ink receiving layer 11 represented by an outer diameter of 112 mm and an inner diameter of 38 mm is designated as a printing area.

  In the area designation screen, a check box D is provided for asking about the presence or absence of a border label. If the outer border label 12 and the inner border label 13 are attached to the CD-R 10, the check box D is checked. Is done. In this embodiment, since the outer edge label 12 and the inner edge label 13 are attached to the CD-R 10, it is assumed that the check box D is checked. Of course, the presence or absence of the outer edge label 12 and the inner edge label 13 may be individually specified.

  When the area is specified as described above and a print execution instruction is received, the computer 50 performs the predetermined print process in the image data conversion module 52a to generate print data. Here, when the check box D is checked on the area designation screen, the outer diameter is shifted 1 mm outside the portion indicated by the image area C in the image to be printed, and the inner diameter is shifted 1 mm inside. Print data for the image area (outer diameter 113 mm, inner diameter 37 mm) is generated. Therefore, on the CD-R 10, ink is ejected to a region within 1 mm outside from the ink receiving layer 11 that is a desired printing region. On the other hand, if the check box D is not checked on the area designation screen, print data for the area indicated by the image area C is generated.

  FIG. 6 shows the CD-R 10 after printing as viewed obliquely. In addition, the area | region shown with a broken line in the figure is an area | region where ink was actually discharged and printing was performed. Since the check box D is checked, the ink receiving layer 11 designated as the print area protrudes 1 mm outside from the outer diameter and is printed 1 mm inside from the inner diameter. That is, since the inner edge label 13 and the outer edge label 12 are respectively attached adjacent to the inner and outer sides of the ink receiving layer 11, the inner edge label 13 and the outer edge label 12 attached to the non-printing area. The ink receiving layers 13a and 12a are also printed out of the ink receiving layers 13a and 12a. Since the ink receiving layer 11 from which ink is ejected, the inner edge label 13 and the outer edge label 12 have ink fixing properties on the surface side, the printer 40 is not soiled without scattering ink.

  FIG. 7 shows how the outer edge label 12 is peeled off from the CD-R 10. In the figure, the outer edge label 12 is peeled off from the left side of the drawing. As a result, the 1 mm printed image protruding on the outer edge label 12 is also removed together with the outer edge label 12. Therefore, a print image of only the image area C originally intended to be printed is left on the ink receiving layer 11 which is a desired print area. The inner edge label 13 is similarly removed. When the outer edge label 12 and the inner edge label 13 are peeled off, both labels have flexibility and strength due to the base materials 12b and 13b, so that they are easily peeled off without breaking in the middle. Can do. Further, since the strength of the adhesive layers 12c and 12b of the outer edge label 12 and the inner edge label 13 is increased, a part of the adhesive layers 12c and 12b does not remain on the CD-R 10 and become unsightly.

  By performing printing on the label surface 10a of the CD-R 10 as described above, printing can be performed without leaving a margin up to the outer edge of the ink receiving layer 11 which is a desired printing region. Further, there is no possibility that the printer 40 is soiled at that time. Further, an error within 1 mm can be allowed for positioning of the disk tray 41 (CD-R10) in the printer 40. In other words, even if the positioning of the disk tray 41 is deviated within 1 mm from front to back and from side to side, the entire ink receiving layer 11 enters the region where ink is actually ejected, so that a margin is left on the ink receiving layer 11. Absent. Therefore, the label surface 10a having a good appearance can be formed without requiring high positioning accuracy from the printer 40.

(2) Second embodiment:
In the first embodiment, the CD-R 10 is supplied in a state in which the outer edge label 12 and the inner edge label 13 are attached in advance. However, the CD-R 10 need not necessarily be supplied with both labels 12 and 13 attached. Absent. That is, it is also possible to purchase the CD-R in a state where the border label is not pasted and paste the border label when printing. Therefore, in the second embodiment, a description will be given of a case where a border label is pasted after a CD-R is purchased.

  FIG. 8 shows an edge label set 116 to be attached to the CD-R as viewed obliquely. In the figure, the edge label set 116 is composed of a carrier 118 and a protective film 119 having a sheet shape substantially the same as that of a CD-R, and an outer edge label 112 and an inner edge label 113. The carrier 118 has adhesiveness on the upper surface, and is adhered to the ink receiving layers 112 a and 113 a of the outer edge label 112 and the inner edge label 113. On the other hand, the protective film 119 is adhered by the adhesive layers 112c and 113c of the outer edge label 112 and the inner edge label 113. That is, the outer edge label 112 and the inner edge label 113 are sandwiched and held by the protective film 119 and the carrier 118 from above and below.

  A common positioning hole 117 is formed at the center of the protective film 119 and the carrier 118, and the center of the outer edge label 112 and the inner edge label 113 is positioned so as to coincide with the same center. The positioning hole 117 has substantially the same diameter as the holding hole formed in the CD-R. The surface of the protective film 119 that adheres to the outer edge label 112 and the inner edge label 113 is subjected to mold release treatment. The adhesive force of the adhesive layer 112c to the protective film 119 is such that the adhesive force of the carrier 118 to the ink receiving layers 112a and 113a. It is weaker than the adhesive strength. For example, by applying a release agent such as silicone on the surface of the protective film 119, a release treatment for the protective film 119 can be performed. By doing so, it is possible to peel only the protective film 119 while the outer edge label 112 and the inner edge label 113 are adhered to the carrier 118 as shown in FIG.

  FIG. 9 shows an attaching device 190 for accurately positioning and attaching the outer edge label 112 and the inner edge label 113 to the CD-R as viewed obliquely. In the figure, the attaching device 190 is formed in a substantially cylindrical shape, and an annular recess 191 having the same diameter as that of the CD-R 110 is formed in a portion corresponding to the upper surface thereof. The annular recess 191 has a predetermined depth, and the bottom surface is flat. A substantially columnar positioning column 192 is provided upright from the center of the annular recess 191. The diameter of the positioning column 192 is slightly smaller than the diameter of the holding hole 114 of the CD-R 110 and the positioning hole 117 of the label set 116.

  The procedure for attaching the outer edge label 112 and the inner edge label 113 to the CD-R 110 is as follows. First, the edge label set 116 from which the protective film 119 has been peeled off as shown in FIG. Set in the recess 191. (FIG. 9 shows a state where the edge label set 116 is already set on the affixing device 190.) Thereby, the adhesive layers 112c and 113c of the outer edge label 112 and the inner edge label 113 are exposed upward. It becomes. At this time, since the positioning hole 117 of the edging label set 116 is formed to have substantially the same diameter as the holding hole 114 of the CD-R 110, the positioning can be accurately positioned by fitting the positioning column 192 into the positioning hole 117. . Next, the CD-R 110 is set in the annular recess 191 with the label surface 110a of the CD-R 110 facing down. Also at this time, the positioning column 192 can be fitted into the holding hole 114 for accurate positioning.

  Therefore, the CD-R 110 and the edge label set 116 can be accurately positioned with respect to each other, and the outer edge label 112 and the inner edge label 113 can also be accurately positioned with respect to the CD-R 110. Then, the edge label set 116 is adhered to the label surface 110a of the CD-R 110 by pressing the CD-R 110 downward from above. The bonded rim label set 116 and the CD-R 110 are taken out from the affixing device 190 and the carrier 118 is peeled off, whereby the outer rim label 112 and the inner rim label 113 are placed on the CD-R 110 as shown in FIG. It can be set as a pasted state. In this embodiment, the outer edge label 112 and the inner edge label 113 are formed in advance so as to be adjacent to the ink receiving layer of the CD-R 110. When the carrier 118 is peeled off, it is not affected by the release agent, so that the outer edge label 112 and the inner edge label 113 can be firmly bonded to the CD-R 110 by the adhesive layers 112c and 113c. Therefore, the outer edge label 112 and the inner edge label 113 are not peeled off from the CD-R 110 together with the carrier 118.

  If the CD-R 110 can be brought into the state as shown in FIG. 1 in this way, it is possible to perform printing with no margin as in the first embodiment. In addition, although what showed positioning using a center hole was shown as an example of a sticking apparatus, a sticking apparatus is not restricted to the thing of such an aspect. That is, the pasting device only needs to have a mechanism for positioning with respect to the border label and the disk-shaped recording medium, and for example, positioning may be performed at the outer edge of the disk-shaped recording medium.

(3) Third embodiment:
FIG. 10 shows a central cross section of a CD-R according to the third embodiment of the present invention. In the figure, an outer edge label 212, an inner edge label 213, and an ink receiving layer 211 are formed on a label surface 210a of a CD-R 210. In this embodiment, the outer edge label 212, the inner edge label 213, and the ink receiving layer 211 are not adjacent to each other, and the ink receiving layer is formed on the inner edge of the outer edge label 212 and the outer edge of the inner edge label 213. The outer edge and the inner edge of 211 overlap each other. That is, before applying the ink receiving layer 211, the outer edge label 212 and the inner edge label 213 are attached to the CD-R 210, and the ink receiving layer 211 is applied and cured so as to overlap therewith. . When the ink receiving layer 211 is applied by screen printing, the opening of the screen mask may be formed so as to overlap the outer edge label 212 and the inner edge label 213.

  With such a configuration, it is possible to perform printing in a desired print area without a margin by the same printing method as in the first embodiment. Specifically, in the area designation screen shown in FIG. 5, the outer diameter of the inner border label 213 is input to the inner diameter box A instead of the actual diameter of the ink receiving layer 211 to the boxes A and B for inputting the inner diameter and the outer diameter. Then, the inner diameter of the outer edge label 212 may be input to the outer diameter box B and the check box D indicating the presence or absence of the edge label may be checked. As a result, each of the ink receiving layers 211 is printed so as to protrude by 1 mm at a portion overlapping the outer edge label 212 and the inner edge label 213. That is, in this embodiment, not the ink receiving layer 211 but a region surrounded by the inner border label 213 and the inner border label 213 is designated as a desired print region. Since the ink receiving layer 211 overlaps, the user cannot measure and acquire the size of the inner border label 213 and the area surrounded by the inner border label 213. Therefore, it is convenient to describe in advance the print area to be specified on the packaging of the CD-R 210 or the like.

  FIG. 11 shows a state in which the outer edge label 212 is peeled off after printing on the label surface 210a of the CD-R 210. In the drawing, the outer edge of the ink receiving layer 211 overlapping the outer edge label 212 is removed together with the outer edge label 212. Of course, the image printed on the ink receiving layer 211 overlapping the outer border label 212 is also removed at the same time. Further, in the present embodiment, a cut 212a for dividing the outer frame label 212 having a circular frame shape is formed, and the outer frame label 212 can be peeled off from a portion where the cut 212a is formed. Therefore, it can peel off in order in the circumferential direction, and the work can be simplified.

  Also in the third embodiment described above, since the ink protrudes to the outside of the desired printing area and the protruding image is removed together with the outer edge label 212 and the inner edge label 213, it is finally desired. A print image can be formed without forming a margin in the print area. Furthermore, in this embodiment, even if there is an error in the positional accuracy in applying the ink receiving layer 211, this can be allowed within the range where the outer edge label 212 and the inner edge label 213 overlap. . That is, the end of the printed image and the end of the ink receiving layer 211 are finally determined by the inner edge and the outer edge of the outer edge label 212 and the inner edge label 213 to be peeled off.
