Yes. Moreover, measures against counterfeiting are required not only for the above-mentioned securities but also for banknotes.

  As one of countermeasures against such counterfeiting, a technique for preventing forgery of securities or banknotes by attaching a member called a thread to securities or banknotes or sandwiching them between paper base materials is considered. Yes. In this technology, a thread formed by cutting a plastic film, thin paper, etc. to a width of about several millimeters is not exposed from the surface of securities or banknotes, or securities such that a part is exposed from the surface. It is inserted between paper bases of banknotes, and authenticity of securities and banknotes is determined by the presence or absence of this thread.

  Furthermore, in recent years, a technique for determining the authenticity of securities and bills using a thread on which an IC chip capable of reading information in a non-contact state is mounted has been considered. In this technology, a thread in which an IC chip is bonded to one side of a film cut to a width of about several millimeters is sandwiched between securities and banknote paper bases, and when using securities and banknotes, an IC is used. By reading the information written on the chip, the authenticity of the securities or bills is determined (for example, see Patent Document 1).

The information reading unit 33 is triggered by the information being read from the predetermined IC chip 11 via the reading antenna 31-1 arranged on the most upstream side in the conveying direction of the continuous sled 10. The information reading operation is performed via the reading antennas 31-1 to 31-7.

  FIG. 5 is a diagram for explaining a method of measuring the mounting pitch of the IC chip 11 using the result of reading from the IC chip 11 via the reading antennas 31-1 to 31-7 in the control unit 30 shown in FIG. (A) is a figure which shows the state when the mounting pitch of the IC chip 11 on the continuous thread | sled 10 is not changing, (b) is the mounting of the IC chip 11 on the continuous thread | sled 10. FIG. It is a figure which shows the state which the pitch expanded.

As shown in FIG. 5, the mounting pitch of the IC chip 11 on the continuous thread 10 before being sandwiched between the continuous label base material 21 and the paper base material 22 is t ₀ , and the reading antenna 31- Assuming that the read width of 1-31-7 is s, the read antennas 31-1 to 31-7 are arranged at a pitch of (6t ₀ -s).

Is not changed from the state before being sandwiched between the continuous label base material 21 and the paper base material 22, information is received from the IC chip 11 through all of the seven readout antennas 31-1 to 31-7. Will be read.

  Further, the pitch of the IC chip 11 on the continuous thread 10 after being sandwiched between the continuous label base material 21 and the paper base material 22 is set so that the continuous thread 10 is continuous with the label base material 21 and the paper base. In the case of spreading from the state before being sandwiched between the materials 22, information is not read from the IC chip 11 through all of the seven reading antennas 31-1 to 31-7. For example, as shown in FIG. In addition, information is read from the IC chip 11 only through the five reading antennas 31-1 to 31-5 among the seven reading antennas 31-1 to 31-7.

  Thus, the number of antennas 31-1 to 31-7 from which information is read from the IC chip 11 is sent to the pitch measurement unit 34 as a read result, and is output from the information reading unit 33 in the pitch measurement unit 34. Using the read result, the mounting pitch of the IC chips 11 mounted on the continuous thread 10 sandwiched between the continuous label substrate 21 and the paper substrate 22 is measured.

For example, as shown in FIG. 5B, information is read from the IC chip 11 only through the five reading antennas 31-1 to 31-5 out of the seven reading antennas 31-1 to 31-7. When it is taken out, as described above, the mounting pitch of the IC chip 11 on the continuous thread 10 is t ₀ , the reading width of the reading antennas 31-1 to 31-7 is s, and the continuous label Assuming that the pitch of the IC chip 11 on the continuous thread 10 after being sandwiched between the base material 21 and the paper base material 22 is t _x , five of the seven readout antennas 31-1 to 31-7 are for readout. Since information is read from the IC chip 11 only through the antennas 31-1 to 31-5,
4t _x ≦ 4 × (6t ₀ −s) + s
5 × (6t ₀ −s) + s <5t _x
From these two formulas, information is read from the IC chip 11 only through the five read antennas 31-1 to 31-5 out of the seven read antennas 31-1 to 31-7. In this case, the pitch t _x of the IC chip 11 on the continuous thread 10 is
6t ₀ -4s / 5 <t _x ≦ 6t ₀ -3s / 4

Although the case has been described by way of example, the number is not limited to these, and even if it is another number, the corresponding numerical value is applied to the above-described mathematical formula, and a continuous label group is obtained. The pitch of the IC chip 11 on the continuous thread 10 after being sandwiched between the material 21 and the paper substrate 22 can be measured.

  The mounting pitch of the IC chip 11 measured by the pitch measuring unit 34 is output to the swing width calculating unit 35, and in the swing width calculating unit 35, based on the mounting pitch of the IC chip 11 output from the pitch measuring unit 34, When the continuous thread 10 is sandwiched between the continuous label base 21 and the continuous paper base 22, the pitch of the IC chips 11 in the continuous direction of the label base 21 and the paper base 22 is constant. The swing width of the continuous thread 10 is calculated so that Details thereof will be described later.

  The swing width calculated by the swing width calculation unit 35 is output to the guide position control unit 36, and the guide position control unit 36 controls the position of the guide 32 based on the swing width calculated by the swing width calculation unit 35. Is done.

  When the position of the guide 32 is not changed from the installation position by the control of the guide position control unit 36, the continuous thread 10 is moved with respect to the continuous paper base material 22 as shown in FIG. It will be in a state of being incorporated in parallel.

  In addition, when the position of the guide 32 is changed from the installation position by the control of the guide position control unit 36, the continuous thread 10 is moved with respect to the continuous paper base material 22 as shown in FIG. It will be in a state where it is incorporated diagonally.

  The continuous thread 10 whose assembly angle is controlled by the guide 32 is then conveyed between the rollers 1g and 1h, and the continuous label base material 21 and the paper base material 22 that have been transported between the rollers 1g and 1h. And is fixed by the adhesive surface of the label substrate 21, and the continuous label substrate 21 and the paper substrate 22 are bonded to each other by this adhesive surface.

The figure which shows the clamping state when the mounting pitch of the IC chip 11 on the continuous thread | sled 10 has not changed, (b) is the clamping state when the mounting pitch of the IC chip 11 on the continuous thread | sled 10 spreads. FIG.

As shown in FIG. 7, when the continuous thread 10 is sandwiched between the continuous label base material 21 and the paper base material 22 by the rollers 1g and 1h, the label base material 21 and the paper base material 22 The mounting pitch of the IC chips 11 in the continuous direction is the mounting pitch t ₀ of the IC chips 11 in a state before the continuous thread 10 is sandwiched between the continuous label base material 21 and the paper base material 22. This pitch t ₀ is a value determined as the mounting pitch of the IC chip 11 on the continuous thread 10 and is also given in advance to the swing width calculator 35, and is a continuous thread drawn from the roller 1c. 10 is sandwiched between a continuous label base material 21 and a paper base material 22 drawn from the rollers 1a and 1b, respectively, the IC chip 11 in the continuous direction of the label base material 21 and the paper base material 22 The swing width (W) of the guide 32 is calculated using the following equation so that the mounting pitch t _x becomes the pitch t ₀ .
W = {(t _x ) ² − (t ₀ ) ² } ^1/2
Therefore, for example, when the mounting pitch t ₁ of the IC chip 11 on the continuous thread 10 measured by the pitch measuring unit 34 has not changed from the pitch t ₀ , as shown in FIG. The width (W) of the guide 32 is calculated as “0” by the width calculation unit 35, and the guide 32 does not change from the set position, so that the continuous thread 10 becomes the continuous label base material 21 and the paper. As a result, the mounting pitch of the IC chips 11 in the continuous direction of the label base material 21 and the paper base material 22 is t ₀ .

Further, when the mounting pitch t ₂ of the IC chip 11 on the continuous thread 10 measured by the pitch measuring unit 34 increases from the pitch t ₀ , the swing width W of the guide 32 is determined by the swing width calculating unit 35. , W = {(t ₂ ) ² − (t ₀ ) ² } ^1/2 , and the guide 32 controls the guide position control unit 36 over the time that the thread 10 is conveyed by the pitch t _0. The label base material 21 and the paper base material of the IC chip 11 at both ends where the mounting pitch is t ₂ are changed by W = {(t ₂ ) ² − (t ₀ ) ² } ^1/2 from the set position. The thread 10 is sandwiched between the label base material 21 and the paper base material 22 at an angle such that the positions in the width direction of 22 are different from each other by {(t ₂ ) ² − (t ₀ ) ² } ^1/2. Go. As a result, the mounting pitch of the IC chips 11 in the continuous direction of the label base material 21 and the paper base material 22 is t ₀ . The control in the guide position control unit 36 is performed so that the guide 32 reciprocates with a predetermined width in the width direction of the continuous thread 10.

Even when the mounting pitch of the IC chips 11 on the thread 10 is changed after the continuous thread 10 is sandwiched between the continuous label base material 21 and the paper base material 20 by the processing as described above, The mounting pitch of the IC chips 11 in the continuous direction of the label base material 21 and the paper base material 22 is set to the IC chip mounting state before the continuous thread 10 is sandwiched between the continuous label base material 21 and the paper base material 22. The pitch t ₀ can be set.

  Thereafter, the continuous label base material 21 and the paper base material 22 in which the continuous thread 10 is sandwiched are conveyed to the cutting unit 40 and cut into a single piece by the cutting unit 40, and the label base material 21 and the paper base material are cut. Thus, the anti-counterfeit sheet 20 in which the thread 10 is sandwiched between the two is produced. The anti-counterfeit sheet 20 cut into a single piece is then conveyed to a predetermined area by the conveyor 50.

  In this embodiment, the continuous label base material 21 is supplied from the roller 1a, the release paper is peeled off from the label base material 21 by the roller 1d, and the adhesive surface of the label base material 21 is exposed. The label base material 21 and the paper base material 22 are bonded to each other while the thread 10 is fixed by the above, but a continuous base material to which no adhesive is applied is supplied from the roller 1a, and the roller 1a and the rollers 1g and 1h are supplied. It is also conceivable that an adhesive is applied to the contact surface of the base material with the paper base material 22 and the base material and the paper base material 22 are bonded to each other while fixing the thread 10 with the adhesive.

  Further, the present invention is not limited to manufacturing a forgery prevention sheet in which the thread 10 is sandwiched between the label base material 21 and the paper base material 22 as shown in the above-described embodiment.
