Description

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

(Background technology) Traditionally, when reading page management marks and printed lines on passbooks used in banks and other financial institutions, the slice voltage V _S has been switched using the method shown in Figure 1. However, in this method, the bankbook was moved over the reading sensor every time the slice voltage V _S was switched, so there were drawbacks such as increased processing time and jamming of the bankbook.

The conventional method will be explained below with reference to FIG.

1 is the printed page of the passbook, 2 is the reading sensor,
3 is an amplifier circuit, 4 is a comparator, 5 is a common control circuit, and 6 is a magnetic stripe R/W unit. When the printed side of the passbook passes through the reading sensor section, the information read by the reading sensor is amplified by the amplifier circuit and then enters the comparator, where it is processed by the slice voltage set according to the instructions from the common control circuit. The sliced results enter the common control circuit. In the common control circuit, the magnetic stripe information (or information from the center) and the input information are compared using comparison logic, and if the results do not match, the slice voltage setting instruction is changed.
The retry operation will be repeated again. In the above, the reason why the page management mark and the printed line cannot be determined based only on the magnetic stripe information is that it is necessary to determine whether the customer has inserted an incorrect page.

(Problems to be solved by the invention) The present invention is intended to improve the above-mentioned drawbacks of the conventional technology. Reference voltage (slice voltage) that reads multiple types of output from sensors
Passbook print data that is sampled simultaneously by V _S , buffered each piece of information, selects information suitable for printing and density from this buffered information, and obtains read data such as page management mark data, bookmark printed line data, etc. It's in the reading method.

(Structure and operation of the invention) The present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram of an embodiment of the present invention, and FIG. 3 is output information obtained in FIG. 2.

In FIG. 2, 1 is a printed page of a passbook, 2 is a reading sensor, 3 is an amplifier circuit, 4 is a comparator, 5 is a buffer, 6 is a common control circuit, and 7 is a magnetic stripe R/W unit. The information read when the passbook print surface passes through the reading sensor section is amplified by an amplifier circuit, then enters each comparator, and is sliced by the slice voltage (V _S1 ~ V _So ) set for each. The results are stored in buffers (1 to n) by a buffer write control signal from the common control circuit 6. Next, the contents of this buffer are read into the common control circuit by a buffer read control signal from the common control circuit, and compared and verified by the comparison logic.

Next, explanation will be given according to the read output information shown in FIG. The output signal from the reading sensor passes through the amplifier circuit and appears as a voltage difference depending on the print density on the passbook, as shown in the figure. This can be applied to multiple slice voltages
The results of slicing by V _S1 to V _So (assuming that V _So >V _S1 here) appear as (comparator output n) to (comparator output 1).

If the data stored in comparator output 2, which has a low slice level, is compared using comparison logic, the back page print data will be included and read together, so the The read information becomes a large value, resulting in a mismatch. Then, when the buffer data of the comparator output 3 is compared as read data, it matches the stripe information (or information from the center), so that a bankbook printed line can be obtained.

(Effects of the Invention) As explained above, in the first embodiment, true page management marks and printed lines can be obtained simply by rereading buffered data, which solves the drawbacks of the conventional method. Problems such as increase in processing time due to retry operations and jamming of bankbooks can be solved.

Claims (1)

[Claims] 1 optically reading the data printed on the bankbook with a reading sensor and magnetically reading data corresponding to the data from the bankbook,
In a passbook print data reading method that compares both reading results to find a match, multiple data obtained by simultaneously sampling the optical reading output from the reading sensor at multiple reference voltages is accumulated in a buffer. A passbook print data reading method characterized in that data that matches a magnetic reading result among accumulated data is recognized as correct reading data.
