Conventionally, printed lines have been detected by detecting the presence or absence of a hyphen mark (-) 2 between the numbers indicating the year, month, and day of the bankbook 1 shown in FIG. 1 using an optical element such as a reflective photo sensor. However, this conventional method uses a photo sensor to monitor a narrow area near the hyphen mark to determine the presence or absence of printing, so to speak.
Dust attached to the bankbook side or dirt on the bankbook side may be mistakenly detected as a hyphen mark.
There is also the inconvenience that a hyphen mark or other characters or symbols printed on the back side of the bankbook paper are erroneously detected as a hyphen mark printed on the front side.

An object of the present invention is to monitor a wider area on a bankbook, including not only hyphen marks but also characters, for example, area 3 indicated by dotted lines in FIG. 1, using an image sensor consisting of a plurality of optical elements. This so-called surface detection concept prevents false detection due to dust attached to the passbook surface or dirt on the passbook surface, and also detects characters or symbols printed on the back side of the passbook paper. By providing a method for detecting printed lines that can accurately detect the presence or absence of printing on a passbook while preventing erroneous detection as characters or symbols, this method can overcome the conventional detection methods described above. It consists in determining the problem.

Input it into a converter and convert it into a multilevel digital signal,
This is applied to a comparator and compared with a predetermined reference value, and the number of signals greater than the reference value is counted within a predetermined area. A capacitive storage circuit for storing multivalued digital data corresponding to at least one element and a circuit for determining the absolute value of the difference are provided between the AD converter and the comparator, and the
The output of the AD converter is stored in the memory circuit, and when the multi-level digital signal corresponding to the next bit of the image sensor is input to the memory circuit, it is sequentially transferred to the next stage memory element, and then transferred to the final stage memory element. The transferred signal and the output signal of the AD converter are applied to a circuit that calculates the absolute value of the difference, and the absolute value of the difference between both signals is applied to the comparator, so that the absolute value of the difference is lower than the reference value.

In the conventional system, the image sensor 7 is the fifth
It was connected to the print detection circuit shown in the figure, and the presence or absence of printing was determined. In FIG. 5, a signal output proportional to the amount of light received by the element of each bit is applied to the amplifier 16 in the order of the bits lined up in the scanning direction from the image sensor 7, and is amplified by the amplifier 16. The output of the amplifier 16 is sent to the peak hold circuit 17
The circuit 17 holds the output level for white from the image sensor 7 and applies the output level to the AD converter 18. The output of amplifier 16 is also applied to the other input of AD converter 18.
The AD converter 18 performs AD conversion on the output of the amplifier 16 based on the output level of the peak hold circuit 17, and generates a multi-value digital signal. For example, the output for white is set to "0", and as the color becomes black, the numerical value increases such as "1", "2", and "3", and when the color is blackest, a signal of "7" is generated. The multilevel digital signal is compared in a comparator 19 with a reference value 20 corresponding to a predetermined density. For example, if the reference value 20 is "4", a signal greater than "4" indicates that the signal has a density higher than a predetermined value. When the comparator 19 receives a signal having a value greater than a reference value 20, it generates a pulse at its output, and the number of pulses is counted by a counter 21, that is, the number of bits having a blackness greater than a predetermined value is counted. do. The counting is controlled by the counting control circuit 22 so that only the signals in the area 3 where the presence or absence of a character or symbol is to be detected can be counted. The counting control circuit 22 performs counting on the counter 21 only while the photo sensor 7 is scanning the area 3 based on a passbook position signal obtained by a passbook position detection device (not shown) provided separately in connection with the passbook feeding mechanism. Supplies a gate signal for When the scanning of the predetermined area 3 is completed, the count value of the counter 21 is transferred to the comparator 23 and compared with a predetermined reference value 24. Comparator 23 generates a signal indicating "printed" at output 25 when the counted value is greater than reference value 24. Therefore, the fifth
According to the circuit shown in the figure, when the number of black background parts with a density equal to or higher than a predetermined density in the area 3 is greater than the predetermined number, it is determined that characters or symbols are printed in the area 3. When this signal indicating "printed" is generated, the bankbook is moved a certain distance and the next line to be printed is set at the printing position of the printing section.

6 and a circuit 28 for determining the absolute value of the difference are provided, but the circuit is the same as the circuit shown in FIG. As described above with reference to FIG. 5, the AD converter 18 generates a multivalued digital signal proportional to the density of the print, and this signal is stored in the first stage of the memory element 27 of the memory circuit 26, and the image sensor Each time a multivalued digital signal corresponding to the next bit is input to the storage circuit, it is sequentially transferred to the storage element 27 at the next stage. The signal transferred to the final stage storage element 27 and the AD converter 1
8 is applied to a circuit 28 for determining the absolute value of the difference, and the circuit 28 determines the absolute value of the difference between both signals. The absolute value of this difference is applied to a comparator 19 and compared with a reference value 20, which
If it is greater than , the counter 21 counts it.
Hereinafter, the presence or absence of printing is determined in the same manner as described above with respect to FIG. In this case, if the number of memory elements 27 is one, the output difference between adjacent bits of the image sensor is compared, if there are two, the output difference is compared with two adjacent bits, and if there are n, the output difference between adjacent bits of the image sensor is compared. compared to the bits of Furthermore, by making the number of memory elements 27 greater than the number of bits for one scanning line of the image sensor 7, it is possible to compare the output difference not only between bits in the horizontal direction but also between bits in the vertical direction.

According to the present invention, compared to the conventional method that inspects only the presence or absence of a hyphen mark, an image sensor consisting of multiple optical elements is used to inspect a wider area, so dust or dirt attached to the passbook surface can be inspected. There are very few false detections due to dirt on the passbook surface, and there are very few cases where characters or symbols printed on the back of the passbook paper are mistakenly detected as characters or symbols printed on the front side of the passbook paper. It is possible to accurately detect completed lines. Furthermore, the method of the present invention can also be used particularly for print-type passbooks that do not use hyphen marks.
