Abstract

PURPOSE:To obtain a page control mark and a printed line data, by sampling a read data by plural slice voltages, buffering this information, and selecting the information being suitable for printing and printing density, from the buffering information. CONSTITUTION:Information of a printing page 1 of a bankbook is read by a read sensor 21, is amplified by an amplifying circuit 3, and after that, is inputted to each comparator 4, and is sliced by slice voltages VS1-VSn set to each. These sliced results are stored in buffers (1-n)5 by a buffer write control signal from a common controlling circuit 6. Subsequently, contents of the buffer 5 are read in the circuit 6 by a buffer read control signal from the circuit 6, are compared and collated with the page control mark and printed line comparing logic, and among the data stored in the buffer 5, the data coinciding with a magnetic strip R/W unit 7 is read as a correct read data.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a reading method for reading print 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) Conventionally, when reading page management marks and printed lines of passbooks used in banks and other financial institutions, slice voltages 8 have been switched using the method shown in Figure 1. In this method, the bankbook was moved over the reading sensor every time the slice voltage VS was switched, so there were drawbacks such as an increase in processing time and the possibility of jamming of the bankbook.

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

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 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 read sensor is amplified by an amplifier circuit and then enters a comparator, where the information is sliced by a slice voltage set according to the instructions of the common control circuit, and the result enters 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 and the retry operation is repeated again. Become. 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 because it is necessary to determine whether the customer has inserted the wrong page.

(Problems to be solved by the invention) The present invention is intended to improve the above-mentioned drawbacks of the conventional technology.The present invention is characterized by a method of optically reading data such as page management marks printed on passbooks and other information such as the next village printed on the book, etc., using a reading sensor. The output from multiple types of reading reference voltages (slice voltages) V8 are simultaneously sampled, this information is individually buffered, information suitable for printing and print density is selected from this buffered information, and page management mark data is , a method for reading passbook print data, such as obtaining read data such as bookkeeping print data.

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

FIG. 2 is a schematic diagram of the embodiment of the present invention, and FIG. 3 is the 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 by the passbook printing surface passing through the reading sensor section enters the latter comparator, which is amplified by the amplifier circuit, and is sliced by the slice voltage (Vs+ ~ vsn) set for each, and this result is common. The data is stored in the buffers (1 to n) by a buffer write control signal from the control circuit 6. Next, the contents of this buffer are read into the common control circuit by a spread read control signal from the common control circuit, and comparison and verification are performed 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 is applied to multiple slice voltages s1 to VBn (here V8
Assume that n>■81), the sliced results appear as (comparator output n) to (comparator output 1).

Here, suppose comparator output 2 with a low slice level
If we compare the stored data using comparison logic, the back page print data will be included and read together, so the read information will have a larger value than the stripe information (or information from the center) and will not match. result. Therefore, 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 the bankbook printing adjacent room 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 replacing the data that has been marked, which eliminates the drawbacks of the conventional method. Problems such as increase in processing time and jamming of bankbooks due to trial operations can be solved.
