Abstract

PURPOSE:To prevent the setting mistake of a printing line due to the surface contamination of paper, by reading the hyphen entered in a medium by an obliquely arranged image sensor while dividing a scanning region correcting the position of the data of each of separate regions to discriminate an already printed line. CONSTITUTION:A reading sensor S3 is obliquely arranged at a predetermined angle in the transfer direction of a passbook 10a and an area detection circuit 12 performs the division of an area at the interval corresponding to the angle of inclination of one scanning interval. That is, for example, when a hyphen is obliquely scanned according to the image data read by the obliquely arranged reading sensor S3, the clock signal corresponding to an interval (a) dividing the area into (n) areas is counted to deliver each of the separate areas. A position correcting processing part 19 performs the position correcting processing of the pixel count data according to the divided areas. That is, as shown by a two-dot broken line, the positions of the divided areas are corrected to the collected into one. By reading the hyphen obliquely and collecting read data in a divided state into one, the detection of a fine line is certainly performed.

[Industrial application field]

The present invention relates to a passbook printer used in financial institutions, etc., and in particular reads a scanning area by dividing it with an image sensor in which hyphens written on a medium are arranged diagonally, and corrects the position of data in each divided area. This invention relates to a passbook printer that can determine which lines have already been printed.

In recent years, bookkeeping machines have been widely used at counters of financial institutions to record transaction details on media such as passbooks and slips. However, since the hyphen lines are thin, reliable reading is not possible due to the spacing width in the sub-scanning direction, and it is difficult to distinguish them from dirt on the paper surface, resulting in line cent errors.Therefore, a method to solve this problem is desired. There is.

[Conventional technology]

As shown in FIG. 5, the bookkeeping machine has a main body 1. trading mode.

Keyboard for inputting the customer's account number and transaction details 2. and a display 3 on which operation processing details and the like are displayed. The device is also connected to a computer center, which is not shown.

As shown in FIG. 6, there is an insertion opening 1a inside the device main body 1.
Conveyance path 41 continuing from
0~R3, press roller R4~R6, inserted passbook 10
Sensors Sl, S2, which detect the leading and trailing ends of a. The reading sensor S3 is composed of a charge-coupled device (CCD) and reads the page barcode and detects the printed line from the hyphen in the print. A page turning section 5 and a printer section 6 are provided on the conveyance path 4. The feed rollers R1 to R3 are connected to a motor (not shown), and the presser rollers R4 to R6 are in a closed state when conveying the passbook 10a.

With such a configuration and function, after the operator presses the bookkeeping mode button on the keyboard 2, the passbook 10a
When inserted into the insertion slot 1a in the direction of arrow A, the passbook 10a
The sensor S1 detects the tip of the paper and transports the paper.

As shown in FIG. 7 (al), the reading sensor S3 secures a certain field of view W and recognizes the printed page barcode near the leading edge of the passbook 10a within this field of view W.

After detecting the hyphen printed on the 0th line of printing, the sensor S
2 until the rear end of the passbook 10a is detected,
The steps from the last line to the printable position of the passbook 10a are edited and judged, and the printable position is automatically conveyed to the printer section 6 and the line is set.

Next, when the details of the transaction, such as the deposit amount, are entered manually using the keyboard 2, the printer section 6 prints out the deposit balance, including the deposit amount, on the bankbook 10a by communicating with the computer center. When printing spans multiple lines, a line feed operation is performed before printing. If there is still print data left after printing up to the last line, the bankbook 10a is transferred to the page turning unit 5, the page is turned over, and the printer unit 6 prints again.

When printing is completed, the passbook 10a is sent in the direction of arrow B and is ejected from the insertion slot 1a. In this way, information is printed on media such as passbooks, slips, and certificates by the bookkeeping machine.

To explain the printed line detection method in detail, in the block diagram of FIG. 12a is a slice level determination circuit that determines slice levels in pixels and relative pixels; 12a is an area detection circuit that counts clock signals corresponding to data read by the reading sensor S3; and 13 is an area detection circuit that detects the print area for the date; 14a and 14b are pixel counters, and 15 is a data read consisting of the same number of registers (not shown) as the pixel counters 14a and 14b. A latch circuit, 16 a main control section, 17 a set line counter, and 18 a medium transport control section.

Therefore, the passbook 10a is transported as described above under the control of the medium transport control section 18, the hyphen is read by the reading sensor S3, the read data is corrected by the level correction circuit 8, and the level is corrected by the slice level determination circuit 11. Based on the image data sent from the circuit 8 and the previous data sent from the image data shift circuit 9, it is determined whether the absolute value of the amount of change, that is, the relative pixel, is greater than a predetermined value, and the relative pixel (change point) is determined. Further, it is determined whether the absolute value of the data from the level correction circuit 8 is greater than or equal to a predetermined value, and the absolute pixel (white or black) is sent to the clock gate circuit 13.

On the other hand, the area detection circuit 12a counts the clock signal corresponding to the data read by the reading sensor S3, detects the area position of the hyphen, and sends a level signal to the clock gate circuit 13.

The output signals of the clock gate circuit 13 from the absolute pixels and relative pixels exceeding the slice level are sent to the pixel counter 1, respectively.
4a and 14b, and is launched into the data read launch circuit 15.

Accordingly, the latched data is sent to the Lee control section 16 and counted by the set row counter 17 in response to the scan end signal sent from the area detection circuit 12a. If there are further printed lines, hyphens are detected in the same way. Even if there are no more printed lines, the passbook 10a is transferred as is, and the sensor S2
When the trailing edge of the passbook 10a is detected, it is counted in the set line counter 17. [Problem to be Solved by the Invention] According to the above conventional method, the passbook is scanned by an image sensor while being transferred, and the hyphen line is is thin, so the hyphen and the reading sensor are parallel, as shown in Figure 7 (bl).
In terms of interval width in the sub-scanning direction, there are only one or two scanning lines,
Since reliable reading is not possible, it is difficult to distinguish from dirt on the paper surface, resulting in line setting errors.

A reading sensor is necessary to recognize page barcodes, so if a reflective optical sensor is used exclusively to detect hyphens, it is possible to prevent row setting errors, but adding a reflective optical sensor will cause problems with the mechanism and circuitry. The problem is that the scale becomes large.

SUMMARY OF THE INVENTION An object of the present invention is to provide a passbook printer that can read thin marks such as hyphens and print line cents using only a reading sensor.
