Abstract

PURPOSE:To increase the margin of back reading and stabilize the reading by discriminating front printing and the back reading in accordance with the sequence of an read output of a character such as date and a reading output of a mark such as a hyphene or comma. CONSTITUTION:Digital signals 8a, 8b outputted from a reading gate circuit are sent with a prescribed sequence by shifting the printing position of a mark such as a hyphene or comma from the printing center of the a character. When the mark signal 8b is outputted to the upper half of the output area of the character signal 8a, it can be decided that the output is the printing line 2a of the back page, and when outputted to the lower half, the output is decided as the output of a printing line 2. Consequently the printing line 2 of the front page can be distinshed from the printing line 1 of the back page regarding the character reading signal 8a by timing sequence generated by the mark reading signal 8b.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a method for reading lines printed on bankbooks and the like in automated equipment installed and used in financial institutions and the like.

(Background technology) Passbooks used in financial institutions such as banks are increasing in consumption due to the expansion of operations such as automatic transfers, automatic cash transfers, salary transfers, etc.
The number of inner sheets is increasing due to the trend towards multi-subject passbooks that combine various subjects such as card loans and deposits into one book.

On the other hand, there are natural restrictions on the total thickness of the passbook due to mechanical constraints such as the passbook transport light, so it is possible to increase the number of inner sheets without increasing the total thickness of the passbook by reducing the thickness of the inner paper. It will be done. In this case, automated transaction devices and other automated equipment must read the printing in the date column to determine which lines have been printed, and reducing the thickness of the inner paper is a margin against misreading caused by reading the back page printing. leading to a decrease in

(Problem to be solved by the invention) The present invention aims to increase the margin for back-reading due to the increase in the number of sheets of inner paper. This system provides a stable reading method for reading printed lines printed on bankbooks, etc. by distinguishing between print and reverse print. The printing position of the symbol in the second area is shifted either up, down, left or right from the center of the area, and the printing lines on the front and back of the form are configured so that they overlap each other. The characters and symbols are read by a reading sensor that converts optical signals into electrical signals, and the seagull sensor is the first
Print line reading that reads the characters in the area and determines that it has been printed when the position of the symbol read from the second area is on a predetermined side with respect to the position of the character read from the first area. It's in the method.

1. (Structure and operation of the invention) Figure 1 shows a deposit passbook 1 used in financial institutions, etc. in an open state, and Figure 2 shows the printed lines printed on the deposit passbook 1. 2 is a block diagram of a conventional method for reading the reading sensor 3.
The output signal of the printed line 2 read by the amplification/shaping circuit 4
is amplified and shaped. 5 is a reading gate circuit which determines the presence or absence of a mark based on a given threshold value from the output signal of the circuit 4 and outputs a digital signal representing the presence or absence of a mark while a reading signal is supplied; 6 is a reading gate circuit for reading and printing a print line;・This is a common control circuit that controls passbook feeding, etc.

FIG. 3 shows the state of the line reading signal when reading is performed using the method shown in FIG. 2, where 2 indicates the printed line;
2a is a printing line on the back page.

In the conventional reading method, the analog signal 7 read by the reading sensor 3 is sliced by a predetermined voltage slice (2) and shaped into a logic signal 8.

A predetermined slice level is set for printing line 2 and printing line 2a on the back page by taking advantage of the difference in the output of the analog signal for reading, but by making the inner paper ring thinner, the output level of both can be adjusted. As the difference becomes smaller (as shown in FIG. 3), the possibility of detecting additional printing on the back page as printing increases and the reading margin decreases.

FIG. 4 is a block diagram of an embodiment employing the method of the present invention, in which 3a is the character reading area of the reading sensor 3, 3b
is the area for reading symbols such as Haiphong. 4a,
4b is an amplification/shaping circuit corresponding to the reading sensors 3a and 3b, and 5a and 5b are the same (4a,
This is a read gate circuit corresponding to 4b. 9 is the above 5a
.

A comparison gate circuit 5b compares the digital signals outputted at a predetermined seedance, and 6 a common control circuit that controls reading of printed lines, printing, bankbook feeding, etc. using the signals outputted from circuit 9. It is a circuit.

FIG. 5 shows the state of the row read signal when reading is performed using the method shown in FIG. 4.

In this method, the analog signals 7a, 7b read by the reading sensors 3a, 3b are sliced by a predetermined voltage slice ■sa + ■, b to form a logic signal 8a.
, 8b. As shown in Fig. 5] By shifting the printing position of the symbol such as 1 ifon\ or 1 force oma from the printing center of the character, the i-taking gate circuits 5a and 5b are created.
The digital signals 8a + 8b outputted from are outputted in a predetermined sequence. In this example ~1
(Well, if the symbol signal 8L is output in the upper half of the output canister of the character signal 8a), then if it is output in the lower half of the print line 2a on the back page, it can be determined that it is the output of print line 2. becomes. That is, it is possible to distinguish between the printed line 2 on the front page and the printed line on the back page based on the timing sequence in which the symbol reading signal 8b is generated in response to the character reading signal 8a, and by monitoring the timing sequence in which the reading signal is generated, Misreading of printed lines on a page is prevented.

(Effects of the Invention) As explained in detail above, it is possible to distinguish between front and back prints of the date by the sequence of reading and outputting equal characters and reading and outputting symbols such as hyphen or comma.
It becomes possible to provide a stable reading method without using advanced technology such as OCR.

Although the printing position of symbols such as hyphen is shifted downward from the center in the above embodiment, it is of course possible to print the symbols by shifting them upward.

Claims (1)

[Claims] In a method for reading printed lines on a form, the form is divided into a first area where characters are printed and a second area where symbols such as hyphens or commas are printed, and the printing position of the symbol in the second area is determined by changing the printing position of the symbol in the second area. The printed lines on the front and back of the form are arranged so that they overlap each other, and the characters and symbols are read by a reading sensor that converts optical signals into electric signals. Characters are read in the area, and when the position of the symbol read from the second area is on a predetermined side with respect to the position of the character read from the first area, it is determined that the printing method is used.
