Further, the pair of connection patterns 21a and 21b are respectively connected to the antenna coil A on the base film P1, and are respectively extended on one surface 26a and the other surface 26b of the base film P1. Specifically, one end portion 27a of the antenna coil A is connected to the proximal end portion of one connection pattern 21a, and one of the connection bumps 28 of the IC chip C is further connected to this portion.

  On the other hand, the other end portion 27b of the antenna coil A is connected to one end portion of a jumper wire (inter-terminal connection pattern) Y wired on the other surface 26b of the base film P1 through the crimping portion 29a.

However, the present invention is not limited to this configuration. . For example, it may have a configuration including an antenna coil and an IC chip C that transmits and receives information via the antenna coil on the base film without having the capacitance adjustment pattern. That is, the configuration of the module substrate is not particularly limited, and includes a configuration that includes at least an antenna coil and an IC chip C that transmits and receives information via the antenna coil and can communicate in a predetermined frequency band. What is necessary is just to have.

  Further, the module substrate 20 laminated on both surfaces of the magnetic layer 30 may be configured with an antenna coil or the like so as to be able to communicate with each other in different frequency bands. A coil etc. may be comprised and it sets suitably so that it may suit a use. Further, in the module substrate 20, the side on which the magnetic layer 30 is formed is not particularly limited, but considering the attenuation of the electromagnetic wave in the base film P1, the base is such that the electromagnetic wave is introduced from the antenna side.

  Here, among the magnetic materials described above, for example, when a magnetic material having a high electrical resistance such as Ni—Zn ferrite is used, it can be made to act as an insulating member. A structure in which the layer 30 is directly laminated can be employed. On the other hand, when using a magnetic material having a relatively low electrical resistance, such as Mn—Zn ferrite, for example, the module substrate 20 is laminated on both surfaces of the magnetic material layer 30 via an electrical insulating layer, for example. .

  As shown in FIGS. 6 and 7, the non-contact type data carrier 40 is configured by covering the non-contact type data carrier inlet 10 with an exterior.

  First, a method for manufacturing the module substrate 20 which is a component of the non-contact type data carrier inlet 10 will be described with reference to FIGS. 8a to 8g, FIGS. 9a and 9b.

  FIGS. 8a to 8g are diagrams schematically showing a basic manufacturing process of the module substrate 20, and FIGS. 9a and 9b are diagrams schematically showing a manufacturing apparatus used in the manufacturing process of FIGS. 8a to 8g. .

  First, as shown in FIG. 8a and FIG. 9a, for example, a PET film R1 made of PET having a thickness of about 30 to 40 [mu] m is rolled out from a PET roll R1 by a roll-off roller 50, and the base film P1 Starts continuous delivery.

  Subsequently, as shown in FIG. 8b and FIG. 9a, rolls 52a, 52b in which adhesive sheets S1, S2 are wound on both side surfaces of the fed base film P1 using adhesive rollers 51a, 51b and The adhesive sheet and the metal sheet are pulled out from the rolls 53a and 53b around which the metal sheets K1 and K2 such as copper are wound, and the metal sheets K1 and K2 are attached via the adhesive sheets S1 and S2.

  Further, as shown in FIGS. 8c and 9a, a resist T is printed using rollers 54a and 54b at predetermined positions on the metal sheets K1 and K2 respectively attached to both surfaces of the base film P1.

  Subsequently, as shown in FIGS. 8d and 9a, the base film P1 on which the resist T is printed on the metal sheets K1 and K2 is guided to the etching tank 55 and subjected to an etching process.

Further, the base end portion of the wiring pattern 29c of the base film P1 is connected to the other end portion of the jumper wire Y through the crimping portion 29b.

  In this manner, the base film P1 in which the jumper wire Y is connected to a predetermined part of the antenna coil A is wound up by the winding roller 58 to form the antenna roll R2.

  Subsequently, as shown in FIGS. 8g and 9b, continuous feeding of the base film P1 in which the antenna coil A and the jumper wire Y are conducted by the unwinding roller 59 from the antenna roll R2 is started. Then, the IC chip C is disposed on the formed surface side of the antenna coil A on the fed base film P1 by the mounting device 60, and the IC chip C is crimped and mounted by the crimping device 61.

  Further, as shown in FIG. 9b, the base film P1 on which the IC chip C is mounted is taken up by the take-up roller 62 to form a module substrate roll R3 in which a plurality of module substrates 20 are arranged vertically and horizontally.

  The method for manufacturing the module substrate roll R3 described above is an example, and is not limited to this. For example, in the manufacturing method described above, the metal sheets K1 and K2 for forming the antenna coil A and the jumper wire Y are attached to the base film P1 via the adhesive sheets S1 and S2. Metal sheets K1 and K2 may be bonded to P1, or after forming a base by sputtering, a metal layer may be formed using a plating tank. Furthermore, when forming the antenna coil A and the jumper wire Y, for example, a screen printing method in which the antenna coil A and the jumper wire Y are formed on the base film P1 with a silver paste by silk printing may be employed.

  Subsequently, as shown in FIG. 11 a, the thickness of the magnetic layer 30 is adjusted to, for example, about 100 to 250 μm by the pressure device 72.

  Subsequently, as shown in FIGS. 10b and 11a, the module substrate 20 is continuously fed from the module substrate roll R3 by the unwinding roller 73, and the module is placed on the magnetic layer 30 whose thickness is adjusted by the roller 74. The substrate 20 is guided and laminated.

  Subsequently, the stacked body in which the two module substrates 20 are stacked through the magnetic layer 30 is guided to the drying furnace 75, and the magnetic layer 30 is dried.

  As shown in FIG. 11a, the laminate obtained by drying the magnetic layer 30, that is, the non-contact type data carrier inlet 10 is wound up by a winding roller 76 to form a non-contact type data carrier inlet roll R4. . At this time, the roll length of the formed non-contact type data carrier inlet roll R4 is, for example, about 5 to 500 m. In this way, a non-contact type data carrier inlet roll R4 in a state where a plurality of non-contact type data carrier inlets 10 are arranged vertically and horizontally as shown in FIG. 12 is formed.

  Next, as shown in FIG. 11b, continuous feeding of sheets in a state in which a plurality of non-contact data carrier inlets 10 are arranged vertically and horizontally is started by the unwinding roller 80 from the non-contact data carrier inlet roll R4. .

  Subsequently, the fed sheet is cut into a predetermined size by using a cutting device 81 with a predetermined position as a reference, and the non-contact type data carrier inlet 10 is manufactured. The sheet after the non-contact type data carrier inlet 10 has been punched is wound up by the collection roller 82 and becomes the collection roll R5.

  As described above, according to the non-contact type data carrier inlet 10 and the non-contact type data carrier 40 of the first embodiment, the module substrate 20 having the individual antenna coils A and IC chips C on both sides is provided, An area for arranging the antenna coil A and the like can be effectively secured. Further, by providing the functions of two non-contact data carriers, for example, it is possible to change the usage of information on the front side and the back side and to improve usability.

  Furthermore, since the two module substrates 20 are arranged via the magnetic layer 30, the transmission / reception magnetic field of the reader / writer introduced from one side passes through the magnetic layer 30 to the introduced side. Will be guided and will have little effect on the other side. As a result, the functions as two independent non-contact data carriers can be used effectively.

  As shown in FIG. 16a, the laminated body from which the magnetic layer 30 has been dried is wound up by a winding roller 156 to form a non-contact type data carrier inlet constituting member roll R7. In addition, when winding a laminated body with the winding roller 156, it winds up so that the metal sheet 110 side may become an outer side.

  Next, as shown in FIG. 16 b, a continuous layered structure in which the metal sheet 110 and the module substrate 20 are laminated via the magnetic layer 30 by the unwinding roller 160 from the non-contact type data carrier inlet constituting member roll R <b> 7.

  Further, since the two module substrates 20 are arranged via the magnetic layer module 120 in which the magnetic layer 30 is formed on both surfaces of the metal sheet 110, the magnetic field for transmission / reception of the reader / writer introduced from one side is In addition to being guided to the introduced side through the magnetic layer 30, it is blocked by the metal sheet 110 and does not affect the other side. As a result, the functions as two independent non-contact data carriers can be used effectively.

  Further, the transmission / reception magnetic field of the reader / writer introduced from one side is guided to the introduced side through the magnetic layer 30, so that even if the metal sheet 110 as a conductor is provided, the metal sheet 110 is provided. Generation of eddy currents inside can be suppressed. As a result, problems such as poor response to the reader / writer caused by the generation of eddy current can be avoided.

  Although the present invention has been specifically described with reference to the first and second embodiments, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention. .

  For example, in the above-described embodiment, the calender roll is used to form the magnetic layer, but instead, the magnetic layer may be formed using a coating apparatus that can drop the magnetic material. The magnetic layer may be formed using electrostatic coating or the like.

  Further, a jumper wire (inter-terminal connection pattern) in which the other end portion 27b of the antenna coil A of the base film P1 on which the antenna coil A and the jumper wire Y are formed is wired on the other surface 26b of the base film P1. When connecting to one end of Y or when connecting the base end of the wiring pattern 29c of the base film P1 to the other end of the jumper wire Y, it is not limited to conducting by caulking. For example, a through hole is formed, and a conductive layer is formed on the inner wall surface of the through hole by sputtering or the like so that the one surface 26a side and the other surface 26b side of the base film P1 are electrically connected. Also good.

  Furthermore, in the first and second embodiments described above, an example in which the electromagnetic induction method including the antenna coil A is adopted for the non-contact type data carrier inlet and the non-contact type data carrier is shown. You may employ | adopt the radio wave system provided with the dipole antenna etc. for the non-contact-type data carrier inlet or the non-contact-type data carrier.
