Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for determining page numbers and printed lines of a bankbook.

Terminal devices of financial institutions such as banks automatically process bankbooks.

For this purpose, a page bar code is preprinted on each page of the passbook to indicate which page it is.
A in Figure 1 is the graph when the passbook Q is opened, and it is a detailed graph of the part marked A in the town.

As can be seen from the figure, each page of the passbook Q has a printing area C where the date, payment amount, etc. are printed, and a non-printing area D where a page barcode B is attached to indicate the page number (number of pages). There is. The pitch of the page barcode B is normally set to 1.5 mm to 2.0 mm in order to avoid unnecessarily enlarging the non-printing area D. On the other hand, the pitch between the print lines in the print area C is usually about 5 mm. For example, in an optical device that detects a page barcode and printed characters or symbols on a printed line, the frequency of the signal generated by detecting the page barcode is two to three times the frequency of the signal generated by detecting the printed line. . Therefore, when amplifying the detection signal of an optical device, if the frequency band of the amplification circuit is designed to match the frequency of the signal generated when the optical device detects a printed line, the signal generated when the optical device detects a page bar code can be used. If signal resolution is an issue and the frequency band of the amplifier circuit is designed to match the frequency of the signal produced by the optical device detecting the page barcode, the optical device can detect the characters or symbols on the printed line. When a signal that is generated by
The output may be divided into several times. It is possible to read the pages and printed lines of a passbook with a single optical sensor, but due to the problems mentioned above, conventionally it has been separated into an optical sensor system dedicated to page barcode determination and an optical sensor system dedicated to printed character determination. These two optical sensor systems are used to determine whether the page bar code is a printed line or not.

This invention was made in consideration of the above problems, and its purpose is to eliminate the need to separate the optical sensor system into two.
An object of the present invention is to provide a determination device that can determine page barcodes and printed lines using a single optical sensor system.

In order to achieve the above object, the present invention includes one optical sensor and an amplifier circuit having two amplifiable frequency bands, and the optical sensor measures a non-printing area or a printing area. The amplification frequency band of the amplifier circuit is switched accordingly.

One of the amplification frequency bands that can be amplified is an optical sensor, and a page bar code is printed in a non-printing area. ) is set to match the frequency of the signal generated when measuring the page barcode (the signal generated when measuring the page bar code), and the other one
One is the optical sensor that detects the printing area (characters or symbols on the printing line).
is set to match the frequency of the signal generated when measuring. Therefore, by switching the amplifier circuit to the corresponding frequency band when the optical sensor is measuring the non-print area and when the optical sensor is measuring the print area, each signal can be determined without error. Embodiments illustrating the present invention will be described in detail below.

FIG. 2 is a front view showing the configuration of an example of a passbook conveyance device of a terminal device in which the determination device of the present invention is used,
1 and 1'' are drive rollers, 2 and 2'' are conveyor belts, 3 is a magnetic head, 4, 5, and 6 are photoelectric switches, 7 is an optical sensor, 8 is a printer, and 9 is a pulse generator.

The passbook shown in Figure 1 is held open from the bottom end P to the belt 2, 2.
First, the lower end P is the photoelectric switch 4.
When detected by the magnetic head 3, the magnetic head 3 starts operating.
It reads the bank code, branch number, account number, etc. magnetically recorded on the cover of the passbook. Next, the lower end P is the photoelectric switch 5
When detected by the optical sensor 7, the optical sensor 7 starts operating. The passbook passes through the optical sensor position sequentially starting from the lowest printed line, and each time a printed line on which characters or symbols are printed passes the optical sensor 7 position, for example, the center, the optical sensor 7 passes the optical sensor position. A detection signal is output from 7.
The photoelectric switch 6 is arranged so that when the lower end of the non-print area D of the passbook reaches the position of the optical sensor 7, the lower end P of the passbook reaches the position of the photoelectric switch 6. Therefore, when the non-print area D of the passbook reaches the position of the optical sensor 7, the photoelectric switch 6 generates a detection output, and switches the frequency band of an amplifier circuit (described later) to which the detection signal of the optical sensor 7 is input. Please note that the passbook has printer 8 on the designated printing line.
A predetermined print is made. FIG. 3 is for showing the structure of one embodiment of an optical sensor and an amplifier circuit according to the present invention, and the optical sensor is indicated by 7 in FIG. 2.

11 is a lamp; 12 is a condensing lens for condensing the light emitted from the lamp 11 and projecting it onto the surface of the bankbook Q; 13 is a photodiode for converting the reflected light from the bankbook Q into electric current;
Reference numeral 4 denotes an amplifier circuit for amplifying the output of the photodiode 13, which includes an amplifier 15 and tuning circuits 16, 17, and 18.

However, 16 is a resistor, and 17 and 18 are capacitors.
Reference numeral 19 denotes a relay circuit, which consists of a coil 20 and contacts 21.

Resistor 16 and capacitor 17 are connected in parallel and also connected to amplifier 15 , and capacitor 18 is connected in parallel to capacitor 17 via contact 21 . Reference numeral 22 denotes a hemiform shaping circuit, which receives the output of the amplifier circuit 14, and outputs the output from an arithmetic control circuit (not shown).

) is entered. Figure 4 shows the frequency-gain characteristic curve of the amplifier circuit 14, where the vertical axis is gain (G) and the horizontal axis is frequency (G).
f) There is a hailstorm. The solid line curve is the characteristic curve when the contact 21 in FIG. This is a characteristic curve when connected in parallel to a circuit. By appropriately selecting the capacitance of the capacitors 17 and 18 and the resistance value of the resistor 16, the frequency band of the solid curve can be set as follows.
To match the frequency of the signal generated when the optical sensor detects characters or symbols on the printed line of the bankbook, and to match the frequency band of the chain line curve with the frequency of the signal generated when the optical sensor detects the page barcode. I can do it. The constants 16, 17, ]8 are set as described above, and the contact 21 is initially opened with the relay 19 in an immobile state.

When a passbook Q with an arbitrary page open is inserted between the conveyor belts 2 and 2'' in FIG. When the detection signal reaches the passbook control circuit (not shown), the passbook control circuit causes the magnetic head 3 to read the bank name etc. magnetically recorded on the magnetic stripe on the cover of the passbook. When the print area C of the passbook Q reaches the position of the photoelectric switch 5, the lower end of the print area C of the passbook Q reaches the position of the optical sensor 7.The output of the photoelectric switch 5 is applied to the passbook control circuit, and the passbook control circuit is connected to the lamp in the optical sensor. 11 is turned on.The light emitted from the lamp 11 is projected onto the passbook Q via the condensing lens 12, and the reflected light is reflected by the photodiode 1.
3, and the photodiode 13 generates an electrical signal in response to the reflected light. When the printing area C advances below the position of the optical sensor 7, during which a printed line passes the position of the optical sensor 7, an electrical signal is generated from the photodiode 13. Since the conveyance speed of the passbook is constant, the frequency of the electric signal from the photodiode 13 generated for each printed line is constant. This electrical signal is input to the amplifier circuit 14. At this time, contact 21 is open and capacitor 18
is released, so the frequency band of the amplifier circuit 14 is as shown by the solid curve in FIG. 4, which matches the frequency of the output signal of the photodiode 3, which is determined by the line spacing of the print lines of the bankbook. Therefore, the output signal of the photodiode 13 is amplified by the amplifier circuit 14 and input to the waveform shaping circuit 22. Next, the bottom P part of the passbook is the photoelectric switch 6.
When the position is reached, the lower part of the non-printing area D of the passbook Q is illuminated,
This means that the position of the optical sensor 7 has been reached.

At this time, a detection signal from the photoelectric switch 6 is generated and applied to the bankbook control circuit, so that the bankbook control circuit drives the relay 19. When the relay 19 is driven, the contact 21 is closed, the capacitor 18 is connected in parallel to the capacitor 17, and the frequency band of the amplifier circuit 14 is as shown by the chain line in FIG.
When the passbook is further conveyed downward and the page barcode B passes the position of the optical sensor 7, the photodiode 13 outputs a signal with a frequency corresponding to the interval between the page barcodes B, which is amplified by the signal amplifier circuit 14. waveform shaping circuit 2
2 is input. Figure 5 is an explanatory diagram of the operation, and the passbook Q

1, the lamp 1 at time t1 as shown in A
When a power supply voltage is applied to 1 and the optical sensor 7 detects a printed line in the printing area C, an output U is generated from the waveform shaping circuit 22 as shown in C.

Next, when the time point when the lower end P of the passbook Q is detected by the photoelectric switch 6 is T2, the relay 19 is driven and the contact point 21 is closed at the time point T2, as shown in the figure. Time T
2 and thereafter, when the page barcode is detected by the optical sensor 7, an output V is generated from the waveform shaping circuit 22. Note that if the upper end of the bankbook Q passes the position of the optical sensor 7 at time T3, the detection output of the photoelectric switch 5 disappears,
Therefore, the passbook control circuit turns off the power to the lamp 11,
And the drive of relay 19 is stopped. Outputs U and V in FIG. 5 are provided by an arithmetic control circuit (not shown).

), the arithmetic processing circuit determines whether the page in question is the last page, determines the number of printed lines, and if further printing is to be done on that page, positions the printed line, and The passbook control circuit receives necessary data from the arithmetic control circuit and uses the printer 8 to perform predetermined printing on the passbook. Since the bankbook control circuit and arithmetic processing circuit that perform such bankbook processing are conventionally well known, detailed explanation thereof will be omitted. The pulse generator 9 generates a pulse every time the drive rollers 2, 2'' rotate by a certain angle for purposes such as positioning the passbook, and inputs the generated pulse to the passbook control circuit.

It is equipped with an amplifier circuit that has two frequency bands that can be amplified, and when the optical sensor is measuring the printed area and when it is measuring the non-printed area (the area with the page bar code). Since the frequency bands of the amplifier circuits are switched, the page and print line can be determined without error without separating the optical sensor system into two.
