  The present invention further comprises a step of punching or cutting a sheet body for each IC chip, and forming one antenna circuit and the other antenna circuit from one band-shaped conductor and the other band-shaped conductor. It is a manufacturing method of the sheet | seat with a non-contact IC tag.

  One aspect of the present invention is a method for producing a sheet with a non-contact IC tag, wherein one band-shaped conductor is held on one base sheet, and one band-shaped conductor is supplied together with one base sheet. is there.

  The present invention provides a method for producing a sheet with a non-contact IC tag, wherein the other strip-shaped conductor is held on the other base sheet, and the other strip-shaped conductor is supplied together with the other base sheet. It is.

  According to the present invention, it is possible to easily position and mount the IC chip with respect to the antenna circuit, and thereby it is possible to easily and easily manufacture the non-contact IC tag-attached sheet.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 3 are diagrams showing an embodiment of a method for producing a sheet with a non-contact IC tag according to the present invention.

  First, the non-contact IC tag-attached sheet will be described with reference to FIGS. The non-contact IC tag-attached sheet 1 includes a non-conductive sheet 25 having an opening 26 and an IC chip 20 housed in the opening 26 of the non-conductive sheet 25 and having electrodes 21 and 22 on both sides. One antenna circuit 34a and one base sheet 31a are sequentially provided on the lower surface of the non-conductive sheet 25, and the other antenna circuit 34b and the other base sheet 31b are sequentially provided on the upper surface of the non-conductive sheet 25. It has been.

  In this case, one antenna circuit 34a extends beyond the IC chip 20 from the left end in the width direction of the non-conductive sheet 25, and the other antenna circuit 34b exceeds the IC chip 20 from the right end in the width direction of the non-conductive sheet 25. (See FIG. 2). The IC chip 20 has an IC chip body 20a, one electrode 21 provided on the lower surface of the IC chip body 20a, and the other electrode 22 provided on the upper surface of the IC chip body 20a. One electrode 21 is connected to one antenna circuit 34a, and the other electrode 22 is connected to the other antenna circuit 34b.

  One antenna circuit 34 a may extend from the right end of the non-conductive sheet 25 over the IC chip 20, and the other antenna circuit 34 b may extend from the left end of the non-conductive sheet 25 over the IC chip 20.

  The non-contact IC tag-attached sheet 1 having such a configuration can be used as a normal non-contact IC tag-attached sheet, but a non-contact IC tag-attached sheet member for producing a normal non-contact IC tag-attached sheet Can also be used.

  In addition, although the example which provided one base material sheet 31a in one antenna circuit 34a and provided the other base material sheet 31b in the other antenna circuit 34b was shown, one base material sheet 31a and the other were provided as mentioned later. The base sheet 31b can also be removed.

  Next, a method for manufacturing a sheet with a non-contact IC tag will be described with reference to FIG.

  First, a laminate composed of one strip-shaped conductor 14a made of copper foil or aluminum foil and paper for bonding and holding the strip-shaped conductor 14a, one base sheet 11a made of PET or polyimide is supplied. . At the same time, a non-conductive sheet 25 made of paper, PET, or polyimide is supplied and laminated on one base sheet 11a and one strip-shaped conductor 14a. In this non-conductive sheet 25, a plurality of openings 26 for accommodating the IC chip 20 are formed in advance.

  The one base sheet 11a, the one strip conductor 14a, and the non-conductor sheet 25 are fed to the nip roller 36 side through the nip roller 35.

  The IC chip 20 having the electrodes 21 and 22 is filled and mounted in the opening 26 of the non-conductive sheet 25 supplied from the nip roller 35 to the nip roller 36.

  Next, the other strip-shaped conductor 14b made of copper foil or aluminum foil on the non-conductive sheet 25, and the other substrate sheet made of paper, PET or polyimide that adheres and holds the other strip-shaped conductor 14b A laminate composed of 11b is supplied and laminated.

  As described above, the base material sheets 11a and 11b and the non-conductive sheet 25 are made of paper, PET, or polyimide, and other high insulation properties, heat resistance, mechanical strength, thinness, and the like are design matters. Considered materials may be used.

  In addition, one strip | belt-shaped conductor 14a is extended from the left end of the width direction to the right side from the center part in the upper surface of one base material sheet 11a toward the supply direction L of FIG. Further, the other strip-shaped conductor 14b extends from the right end in the width direction to the left side slightly from the central portion on the lower surface of the other base sheet 11b. For this reason, one strip-shaped conductor 14a and the other strip-shaped conductor 14b overlap each other in the width direction in the vicinity of the IC chip 20 (see FIG. 2).

  Thus, the laminated body which consists of one base material sheet 11a laminated | stacked in this way, one strip | belt-shaped conductor 14a, the nonconductor sheet 25, the other strip | belt-shaped conductor 14b, and the other base material sheet 11b is obtained. The nip roller 36 is pressed. In this case, the non-conductive sheet 25 and one strip-shaped conductor 14a and the non-conductive sheet 25 and the other strip-shaped conductor 14b are bonded via an adhesive (not shown).

  In this way, the sheet body 10 including the one base sheet 11a, the one strip conductor 14a, the non-conductor sheet 25, the other strip conductor 14b, and the other base sheet 11b is obtained. Next, the sheet body 10 is cut into individual IC chips by the cutter 27 in a direction orthogonal to the supply direction L of the sheet body 10.

  In this case, the sheet body 10 is cut, and the antenna circuits 34a and 34b are formed from the one strip-shaped conductor 14a and the other strip-shaped conductor 14b, respectively.

  Instead of cutting the sheet body 10 in a direction orthogonal to the supply direction L of the sheet body 10, the sheet body 10 may be punched for each IC chip.

  In this way, the non-contact IC tag-attached sheet 1 having the base sheet 31a, the antenna circuit 34a, the non-conductive sheet 25 on which the IC chip 20 is mounted, the antenna circuit 34b, and the base sheet 31b is obtained. It is done.

  As described above, according to the present embodiment, the non-conductive sheet 25 is laminated on the one strip-shaped conductor 14 a held by the one base sheet 11 a, and the IC is placed in the opening 26 of the non-conductive sheet 25. The sheet body 10 can be obtained by mounting the chip 20 and then laminating the other strip-shaped conductor 14 b held by the other base sheet 11 b on the non-conductive sheet 25. And the sheet | seat 1 with a non-contact IC tag can be easily obtained by cut | disconnecting this sheet | seat body 10 for every IC chip 20. FIG.

  In this case, since the IC chip 20 can be mounted simply by housing the IC chip 20 in the opening 26 of the non-conductive sheet 25, the positioning and mounting work of the IC chip 20 can be performed easily and easily.

  In the above embodiment, an example is shown in which one strip conductor 14a is held by one base sheet 11a and the other strip conductor 14b is held by the other base sheet 11b. Not only may one base sheet 11a be removed and only one strip conductor 14a be supplied, but the other base sheet 11b may be removed and only the other strip conductor sheet 14b may be supplied.
