Abstract

PURPOSE:To improve a repayment processing efficiency by deciding the number of the dots of the black of a fixed character area simultaneously printed with a printed character on a betting ticket in a density decision part and automatically switching a threshold level by a threshold selecting part according to the result to read it. CONSTITUTION:When the printed character 24 of the character recognition area 22 of the betting ticket 21 cannot be recognized, a recognition control part 7 outputs a recognition NG signal 9 to a repayment control part 11 activates the density decision part 13, the density decision part 13 counts the black of the area of the fixed character 23 of the betting ticket 21 and inputs the counted result to the threshold selecting part 14. The threshold selecting part 14 stores the execution of an optimum binarization according to the selection of a voltage comparator 4, inputs a selection code to a multiplexer 5 and switches the voltage comparator 4 to read the betting ticket 21 which cannot be recognized. Thereby, since the threshold of the betting ticket which cannot be recognized can be automatically selected and read, the repayment processing efficiency is improved.

Description

[Detailed Description of the Invention] [Summary] A voting ticket refund device that optically reads printed characters on a voting ticket and reads the characters by mask matching,
The number of black dots in the fixed character area of the first read image data is counted by the density determination section, and the threshold value of the voltage comparator, which is provided in multiple types, is selected based on the counting result. Since the reading is repeated by switching to the threshold value, voting tickets with different densities can be easily read.

[Industrial application field]

The present invention relates to a voting ticket refund device that optically reads printed characters on voting tickets and performs character recognition by mask matching.

The voting ticket that corresponds to the winning number in public competitions such as horse racing, bicycle racing, auto racing, boat racing, etc. is refunded by a voting ticket refund device, which optically reads the recognition of the characters printed on the voting ticket. This is done by mask matching, which compares the printed characters with a standard pattern of characters stored in the device. However, when the characters printed on the voting ticket cannot be recognized due to the condition of the printer at the time of printing, that is, the density, the fixed characters on the voting ticket are used. There is a need for the development of a voting ticket payout device that can count the number of black dots in an area and automatically switch the threshold value based on the counted value.

[Conventional technology]

Conventional voting ticket refund devices use mask matching, which involves reading the characters printed on the voting ticket with an optical reader and comparing the read characters with a standard pattern of characters stored in the device. If it cannot be read, visually compare the fixed characters printed in the character recognition area with the 'a lightness. If the fixed characters are lighter than the fixed characters, change the threshold to "light", and if it is dark, change the threshold to "dark". It is designed to be read by switching to .

[Problem that the invention seeks to solve]

In the above-mentioned conventional voting ticket refund device, the characters printed on the voting ticket vary depending on the printer condition, i.e. the degree of use of the ribbon, and the difference in the printing pressure of the hammer, so this is visually determined and the shading is dealt with. Since the threshold value switching operation is performed by the operator, there is a problem in that the refund processing efficiency is reduced.

[Means for solving problems]

The present invention solves the above-mentioned problems by determining the number of black dots in the fixed character area of a voting ticket using a density determining section, and automatically selecting and switching a threshold value by comparing the determination result with the printed characters. The present invention provides a voting ticket refund device with the following features.

In other words, we have developed a voting ticket refund device that optically reads printed characters on voting tickets and performs character recognition through mask matching.
a density determination section that counts the number of black dots in the fixed character area of the first read image data when the printed characters on the voting ticket cannot be recognized, and a determination result of this density determination section;
This problem can be solved by switching the threshold selection section and reading repeatedly.

[Effect]

In this voting ticket refunding device, the density determination unit determines the number of black dots in the fixed character area that is printed at the same time as the printed characters on the voting ticket, and the threshold selection unit automatically sets the threshold based on the result. Since the values are switched and read, voting tickets can be quickly verified and refund processing efficiency is improved.

〔Example〕

1 and 2 are diagrams explaining one embodiment of the present invention, in which FIG. 1 is an example of printing a voting ticket, and FIG. 2 is a block diagram.

The printed characters 24 on the side of the voting ticket 21 are converted from black and white into a voltage level by the image sensor 1, and this voltage level is amplified by the amplifier 2. The output of this amplifier 2 is then binarized by a binarization section 3 and sequentially stored in a memory 6.

The binarization unit 3 is composed of a plurality of voltage comparators 4 with different threshold values (light, standard, and dark are shown in the figure) and a multiplexer 5, and a voltage comparison selected by the multiplexer 5. When the output of the device 4 is written to the memory 6 and all the image data of the ticket face is stored in the memory 6, the stored image data is subjected to mask matching with the standard pattern 10 of characters in the recognition unit 7. It will be done.

If all the characters (voting information) have been recognized, the recognition section 7 outputs a recognition OK signal to the refund control section 11 and transfers the voting information. The refund control unit 11 that has input the voting information displays this voting information on the display unit 12 and sends it to a center computer (not shown).
receives the refund cylinder, rejection judgment, and refund amount from the center computer, and displays this information on the display unit 12.

By the way, the printed characters 2 in the character recognition area 22 of the voting ticket 21
When recognition of step 4 is not possible, the recognition control unit 7 determines that the recognition is not successful.
When the double signal (unrecognizable signal) is output to the refund control unit 11, the refund control unit 11 activates the density determination unit 13, and the density determination unit 13 processes the black count in the area of the fixed character 23 of the voting ticket 21. The counting results are sent to the threshold selection section 14.
Enter. The threshold selection section 14 stores which voltage comparator 4 should be selected to perform optimal binarization based on the input black count value, and inputs the selection code to the multiplexer 5.

Then, the multiplexer 5 switches the voltage comparator 4 according to the selection code from the threshold selection section 14 to prepare for reading the voting ticket 21 that could not be recognized.

In this example, the threshold value is set to standard and dark.

Thin 3F! Normal reading is “standard”.
has been selected, the recognition NG signal 9 is input to the refund control unit 11, the concentration determination unit 13 is activated, and the voting ticket 2 is
The black of the fixed character 23 of 1 is counted, and if the counted value is greater than the specified value, the dark threshold value is selected, and if it is less than the specified value, the light threshold value is selected.

When the recognition NG signal 9 is input, the refund control unit IJ displays this on the display unit 12 and instructs the operator to read the voting ticket 21 that could not be recognized again.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the threshold value of the unrecognized voting ticket can be automatically selected and read, which improves the efficiency of refund processing and alleviates congestion at the time of refund. Extremely effective.
