  And if the banknote 30 is inserted from one side of the slit 46, a detection sensor will detect it and a drive device will drive. As a result, the bill 30 moves in the slit 46 in the direction of the white arrow at a constant speed, passes through the slit 46, and magnetic information (including paper quality) recorded on the bill 30 by the magnetic sensor is magnetically read. It is read by the device 42. In this case, since the bill 30 is moved in the direction of the arrow at a constant speed by the driving device, the magnetic information of the bill 30 can be read accurately.

  Then, the comparison / determination means compares the read magnetic information on the basis of preset basic information of the threshold range, and when it is determined to be a true bill, the control device 11 does nothing and terminates. To do. If the bill 30 is determined to be a true bill, the control device 11 may display on the display unit 14 that the bill 30 is a true bill.

  When the compared banknote 30 is determined to be a bill, the control device 11 outputs and displays on the display unit 14 that the bill 30 is a bill. The control device 11 displays on the display unit 14 that the bill 30 is a bill, and at the same time outputs a predetermined alarm sound from the speaker 4 or the speaker 8 (corresponding to the means for outputting the authenticity determination result of the present invention). You may sound.

  Thus, the additional information reading means (magnetic reading) for reading the information for authenticity determination other than the information that can be read by the information reading means of the first to third embodiments on the portable terminal device 1 (external connection unit 157). Since the apparatus 42) can be connected, it is possible to perform authenticity determination based on paper quality, ink material, and the like in addition to the optical pattern and image of the banknote 30.

  In the portable terminal device 1, only the information of the banknote 30 is detected by the additional information reading means (magnetic reading device 42), and the authenticity determination may be transmitted to the host computer 38 by the data communication function of the portable terminal device 1. . Then, authenticity determination is performed by the comparison determination means of the host computer 38, and the determination result (a bill or a genuine note) is returned to the mobile terminal device 1 that has received the information on the banknote 30. Thereby, the burden of the control apparatus 11 provided in the portable terminal device 1 can be lightened, and the information to be held in the memory 13 and the software for determining the authenticity of the banknote 30 can be simplified.

  Moreover, although the information of the banknote 30 was read by the additional information reading means (magnetic reader 42) and the authenticity determination was performed by the control apparatus 11 of the portable terminal device 1, the information of the banknote 30 was read by the additional information reading means. It does not matter even if it is carried out until authenticity determination. Thereby, the burden of the control apparatus 11 provided in the portable terminal device 1 can be lightened, and the information to be held in the memory 13 and the software for determining the authenticity of the banknote 30 can be simplified.

  Further, the magnetic reading device 42 is provided with a transmissive sensor (a light emitting element and a light receiving element are arranged at a predetermined interval), and the transmitted light (brightness and darkness) of the bill 30 driven by the driving device by this transmissive sensor. The pattern 30 may be detected and compared with the basic information (in this case, the basic light / dark pattern of transmitted light) stored in the memory 13 in advance, the authenticity of the banknote 30 may be determined. Thereby, the authenticity determination of the banknote 30 can further be improved.

  In addition, although the banknote 30 for authenticity determination was demonstrated with 1000 yen in the Example, the banknote 30 is not restricted to 1000 yen, It may be banknotes, such as 2000 yen, 5000 yen, and 10000 yen. In this case, the control device 11 for determining the authenticity of the banknote 30 may include a program and basic information that can automatically recognize the banknote and determine the authenticity.

  Although the mobile terminal device 1 has been described as a mobile phone, the mobile terminal device 1 is not limited to a mobile phone, and a PDA 50 (FIG. 5) capable of performing a camera function, sending / receiving mail, the Internet, etc. although it cannot make a call. It doesn't matter. The PDA 50 is a mobile terminal device different from the mobile terminal device 1 of the present invention.

  In the embodiment, the paper sheets are described using the banknotes 30, but the paper sheets are not limited to the banknotes 30, and may be cash vouchers such as gift certificates, securities, tickets for theaters, or the like. Also in this case, since the authenticity of these paper sheets can be determined by the mobile terminal device 1 as in the embodiment, the convenience of the mobile terminal device 1 can be further improved.

  Moreover, although the authenticity determination of the banknote 30 was performed separately in each Example, the authenticity of the banknote 30 is not restricted to this, The combination of Example 1 and Example 2, Example 4, Example 1, and Example 2 The authenticity of the banknote 30 may be determined by a combination of the above. Thereby, the authenticity determination accuracy of the banknote 30 can be further improved.

  Of course, the present invention is not limited to the above-described embodiments, and the present invention is effective even if various other modifications are made without departing from the spirit of the present invention.
