(3) is a detection circuit composed of a diode, (4) is a low-pass filter that detects the envelope signal from the detection signal, and (5) is a signal waveform of the low-pass filter that is sampled at a predetermined period. A/D to convert to digital value
It is a converter. (6) is a processing circuit that determines the authenticity of each predetermined section of the inspected banknote based on the output data of the A/D converter (5) and outputs a "true" signal or a "false" signal.
It is equipped with M (7) and ROM (8). Also (9
) is a determination means that determines whether a banknote is "authentic,""suspicious," or "fake" based on each signal from the processing circuit (6).
If it is determined to be “authentic,” the drive circuit as a drive control means.
to rotate the conveying means (described later) in the normal direction, and
If it is determined to be false, the conveying means is reversed. αD is a pulse generator that outputs a pulse in response to the movement of the banknote to be inspected. In the second meat, the inspection paper inserted from the input port oz was
) is held between a pair of belts (14) and passes through the magnetic head (1), and the pulse generator aυ is configured to output pulses in synchronization with the rotation of the roller aω caused by the movement of this bill. In other words, the roller α9 is formed with radially spaced ribs (lf9) at equal intervals.
The optical sensor (I7) detects the slit a by the rotation of the roller α9.
When l is detected and a detection signal is output, the pulse generator αυ
This detection signal is amplified by the amplifier circuit, and the waveform shaping circuit α
It is designed to output pulses by shaping the waveform in the field. (to) is a division control circuit that divides the identification surface of the inspection banknote into n ways, and when the pulses from the pulse generator (11) are counted and a predetermined value is reached, timing signals T1, T, and
...T, is output to the processing circuit (6)K.

RA M (7)に遂次記憶させる。With the above configuration, when a banknote is inserted through the slot (12) and the pair of pels (14) rotate forward to take in and transport the banknote, the banknote passes through the magnetic head (1). Therefore, the detection signal shown in FIG. 3 is outputted from the amplifier circuit (2) in accordance with the printing pattern of the banknote. And the detection signal is detected by the detection circuit (3)
After the signal is detected by the low-pass filter (4), the envelope signal shown in FIG. 4 is detected by the low-pass filter (4). The A/D converter (5) samples the envelope signal and converts it into a digital value every time a pulse is introduced from the pulse generator α9, but the processing circuit (6) is connected to the A/D converter (5). The data introduced from the RAM (7) is sequentially stored.

て「偽」信号を判定手段に出力する。By performing A/D conversion on the envelope signal in this way, the digital value also increases where the peak value of the detection signal is large,
Furthermore, where the peak value is small, the digital value is also small, making it possible to capture the characteristics of the amplitude of the detection signal. The compartment control circuit (2) counts the pulses generated in the pulse generator aυ as the banknotes move, and outputs a timing signal T1 to the processing circuit (6) when a predetermined value is reached. Therefore, the processing circuit (6) compares the envelope signal data stored in the RAM (7) with the data programmed in the ROM (81) indicating the case of genuine banknotes for that section, and calculates the envelope signal data within the permissible range. If it matches the standard data,
This section of the bill is determined to be genuine and a "true" signal is output to the determining means, and if they do not match, a "false" signal is output for this section to the determining means.

いては真正と判定する方法である。In this way, the processing circuit (6) determines the truth or falsehood for each section and each time determines whether the determination means (9) is "tcr true" or "false".
Output a signal. As the discrimination process for each section, the fifth
As shown in the figure, discrimination is made based on the ratio a/b between the maximum peak value a and the width of the envelope signal, and the processing circuit (
6) extracts the maximum data a of the envelope data sampled in one section stored in RAM (7) K, and detects the number of envelope data having a value equal to or greater than a predetermined value C. Calculate the ratio. Then, it is compared with the data programmed in the ROM (81) indicating the ratio in the case of genuine banknotes for that section, and if the calculated ratio value matches this standard data within the tolerance range, then this section of the banknote is This is a method for determining authenticity.

On the other hand, if the count value due to the "false" signal is "1" or more and within the predetermined setting value, it is determined that the banknote is a suspicious banknote, and the drive circuit (10 is activated and the pair of bells) (14) is reversed and processed. A reprocessed signal is output to the circuit (6). Then, based on the detection signal of the magnetic head (1) generated when the suspect banknote is returned and conveyed by reversing the bell l-f14), the authenticity determination operation is performed again for each section of the printing pattern of the suspect banknote from the opposite direction. Repeatedly, the processing circuit (6) outputs "true" and "false" signals for n sections. Here, the determination means (9)
If the count value due to the "false" signal is "0", the suspect banknote is determined to be a genuine banknote, and the drive circuit 0[ll is activated to stop the reverse rotation of the belt (14) and to rotate it forward. The banknotes are taken in, conveyed, and stored. If the banknote is determined to be a suspect banknote or a counterfeit banknote in this re-judgment, the return conveyance is continued and the banknote is returned to the input slot az. In other words, banknotes that are determined to be suspect banknotes during normal rotation conveyance on the belt side are
During the reverse return conveyance according to (14), the printing pattern in the reverse direction is again determined by the determination means, and when the bill is determined to be a genuine bill, the return conveyance is stopped, the banknote is taken in, conveyed, and stored.

信頼感も向上する。(G) Effects of the Invention The present invention determines whether a banknote inserted through an input slot is a genuine banknote, a suspect banknote, or a counterfeit banknote, and when the banknote is determined to be a genuine banknote, the conveying means is rotated in the normal direction to remove the banknote. If the banknote is taken in and determined to be a suspicious banknote or a counterfeit banknote, the conveying means is reversed and returned, and in the case of a banknote that is a doubtful banknote, the authenticity is determined again while the banknote is being reversed.
If the banknote is determined to be a genuine banknote, the return conveyance is stopped and the banknote is taken in, conveyed, and stored. Therefore, the return rate of banknotes can be reduced without lowering the identification accuracy. This will reduce the number of inconveniences such as items being returned despite the fact that the item was returned, and the customer's sense of trust will improve.
