Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mark sheet and a ticket issuing machine used for recognizing a mark written on a card, such as a betting ticket, and issuing a ticket, and particularly to a reading error when inputting from both sides of the mark sheet. The present invention relates to a mark sheet with improved ticketing reliability and ticket issuing machine using the same.

2. Description of the Related Art Voting tickets, which are so-called betting tickets, are betting-types such as wins / wins / consecutive wins / horse wins (hereinafter referred to as formulas), stadium names (hereinafter referred to as stadiums). Name)), race number, group number such as frame number and horse number, and voting amount for each group number are printed and issued by inputting them into a voting ticket issuing machine using a mark sheet or the like. The mark sheet used for input for issuing such a voting ticket is called a voting card, and has a width of about 12 cm and a length of about 8 cm.
It is of the order of magnitude.

Due to the limited size of voting cards,
The number of designated group numbers and voting amounts (this is called bet) is limited to, for example, 5 pairs at maximum. Therefore, in the case of voting bets larger than the standard maximum number of bets, such as 7 bets, multiple voting cards had to be used even in the same race.

Therefore, as the number of bets increases,
In order to prevent an increase in the number of voting cards, mark fields are provided on both the front and back sides of the voting cards, for example, 5 bets from the front and 5 back,
A voting card capable of voting with a maximum of 10 bets is considered.

[0005]

[Problems to be Solved by the Invention] When a mark field is provided on both the front surface and the back surface of a mark sheet such as a voting card,
Marks written on one side may blur and show through. Therefore, when the mark sheet is optically read, there is a possibility that an erroneous recognition may occur in which a blank mark column is determined to have a mark due to show-through.

For example, in an entry frame in which only one (or a predetermined number) of marks can be entered in a plurality of mark fields, such as the expression-specific mark portion and the assembly number mark portion in a betting ticket voting card, Even if an unfilled mark column is recognized as having a mark, it is possible to immediately determine that an error has occurred by logically checking the number of marks. However, any number of marks can be entered in the voting amount input frame, and the total of the marked numbers is recognized as the voting amount. Such an input frame is called the total input section. If the blur of the mark written on the other side in the total input section is the show-through, an error cannot be detected by the logical check of the number of marks and the voting amount is erroneously recognized. Will be lost.

In order to solve this problem, the paper thickness of the voting card is made thick enough not to show through even if some blurring occurs, or a water repellent sheet or the like is sandwiched between the front surface and the back surface to form a layered structure. However, there is a possibility that the card will not bleed, but there is a problem that the cost of producing the card becomes high, and that handling and storage of the card becomes inconvenient.

Further, when reading marks on both the front surface and the back surface from a mark sheet having mark fields provided on both the front surface and the back surface, it is necessary to insert the mark sheet into the reading unit in the forward / reverse direction and the front / back direction. It is necessary to read correctly and efficiently regardless of the orientation. It may be possible to restrict the forward and reverse insertion directions or the front and back directions when inserting the mark sheet, and eject the mark sheet as an error if it is incorrect, and prompt re-insertion.
It is very inconvenient for users and it takes time to issue tickets.

Further, the mark detection processing is performed assuming that the mark columns exist in a matrix pattern for all the areas on both the front surface and the back surface of the mark sheet. Unnecessary mark detection is performed even in the area where the mark columns do not actually exist. Therefore, there is a problem that it takes time to detect the presence or absence of a mark.

The present invention solves the above problems, prevents reading errors due to bleeding of entry marks when inputting from both sides of a mark sheet, and improves the reliability of ticket issuing, and a ticket is issued using the mark sheet. The purpose is to provide a ticket issuing machine. Even if the mark sheet is inserted in any direction (forward / reverse) and direction (front / back),
It is an object of the present invention to enable efficient and correct detection of marks. Furthermore, another object of the present invention is to enable speeding up of the mark detection process by detecting the presence or absence of a mark only in the necessary mark fields on the front surface and the back surface.

Indicates a ticket issuing mechanism unit that prints and issues voting tickets and the like.

In the present invention, as shown in FIG. 1A, the mark writing portions 3 and 3'are provided on both the front surface and the back surface of the mark sheet 1. In the mark number indefinite input unit 4 or 4 ′ such as a total input unit in which a variable number of marks on the front surface or the back surface is written, the individual mark fields are arranged at positions not overlapping with the individual mark fields on the other surface.

That is, as shown in FIG. 1B, the front mark column 5 and the back mark column 6 are, for example, vertically or
And are arranged at positions displaced by a half pitch to the left and right. At least in the mark number indefinite input section 4 or 4 ', the mark field of the other surface is arranged so as not to overlap with the mark field as shown in the figure, but the mark entry section 3 other than the mark number indefinite input section 4 or 4' Even in 3 ', it is desirable that the positions do not overlap.

Card identification marks 2 and 2'for identifying the front surface and the back surface or these and the card type are printed and arranged on the left and right ends of the front surface and the back surface of the mark sheet 1, respectively.

The reading unit 10 shown in FIG. 1 (C).
When the mark sheet 1 on which the necessary marks are written is inserted into the
The image on one side is read. Further, the second surface reading unit 12 reads the image on the other surface of the mark sheet 1.

The mark detector 13 detects the timing mark 7 in each read image, and first analyzes the card identification mark 2 or 2 '.
This analysis result is coded to obtain the card identification code.

The reading unit 10 is provided with a mark position table 14 for each card identification code,
The mark position table 14 stores the position information of the mark field that is predetermined for each card identification code. The mark position table 14 may be stored in advance in a non-volatile memory or may be downloaded from the ticket issuing control unit 15 when necessary.

The mark detecting section 13 is provided with a timing mark 7
The mark position table 14 corresponding to the card identification code is referred to, and the presence or absence of the mark is detected only in the designated mark column. Information on the presence or absence of the detected mark is notified to the ticket issuing control unit 15 as a result of reading the mark sheet 1 together with the card identification code.

From the reading result of the mark sheet 1, the ticket issuing control unit 15 performs a logical check on the entry of necessary marks, whether the number of marks is too large, or the like. If necessary, a logical check regarding operation such as whether or not a nonexistent group number is designated is performed, and if the ticket can be issued, the ticket issuing mechanism unit 16 is instructed to issue a voting ticket or the like. The ticket issuing mechanism unit 16 is instructed by the ticket issuing control unit 15 to
Print and issue voting tickets, etc.

The operation of the present invention is as follows. (1) The individual mark fields on the front and back of the mark sheet 1 where the number of marks is indeterminate are arranged at the front and back sides so that the marks do not overlap. Read errors can be prevented.

(2) In particular, by shifting the front mark column 5 and the back mark column 6 by a half pitch as shown in FIG. 1 (B), the mark column on the other surface is displaced from the timing mark 7. No more erroneous reading with or without show-through.

(3) Card identification mark 2 for identifying the front and back surfaces of the mark sheet 1 or these and the card type
2'is arranged at the left and right ends of the front and back surfaces, respectively, so that whether the mark sheet 1 is inserted into the reading unit 10 in the forward / reverse direction or the front / back direction, The presence or absence of a mark can be efficiently detected by correctly identifying the back side or these and the type of card. In particular, since the card identification marks 2 and 2'are arranged at both left and right ends, mark detection can be started in parallel with the image reading before the entire image reading is completed, and the mark detection can be speeded up. become.

(4) Since mark detection is performed using the mark position table 14 corresponding to the card identification marks 2 and 2 ', various mark sheets 1 can be flexibly dealt with. Further, since it is possible to perform the mark detection processing only on the required mark fields on the front surface and the back surface, instead of detecting the presence or absence of the mark in the entire area of the mark sheet 1, it is possible to shorten the processing time of the mark detection, It becomes possible to issue tickets such as voting tickets in a short time.

[0026]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram showing an example of a voting card according to the mark sheet of the present invention. FIG. 2 (A) and FIG.
(B) shows the front and back of one voting card.

The voting card shown in FIG. 2 is a mark sheet used for purchasing a so-called betting ticket, and card identification marks 2, 2 ', a timing mark 7 are printed on the front surface or the back surface, and a bet is used as a mark entry portion. Marks for each ceremony to mark the type of ceremony, place name mark to mark the stadium name, race number mark to mark the race number, group number mark to mark the frame number / horse number, voting for each group number An amount mark portion (total input portion) for marking the amount is provided. Of these mark entry parts, the amount mark part is
This corresponds to the mark number indeterminate input units 4 and 4'in FIG.

FIG. 3 shows an example of the amount mark portion of the voting card shown in FIG. The amount mark part is a total input part in which marks can be entered in a plurality of mark fields. For example, the voting amount of "18000 yen" is "10", "5" in the number mark entry frame. , Mark the "3" mark column and mark "thousand yen" in the unit mark entry frame. In such a total input unit, since it is not possible to determine an error by a logical check based on the number of written marks, even if the written marks on the back surface appear on the front surface due to bleeding, only the marks in the front surface mark column can be reliably checked. Need to read.

FIG. 4 is a view showing the arrangement of the mark columns as seen from the surface of the voting card. As shown in FIG. 4, the position of the back mark column 6 is displaced from the position of the front mark column 5 by a half pitch. Even if bleeding occurs due to show-through at the position of the back mark column 6, it is outside the predetermined mark reading area 9 and therefore is not erroneously read. That is, if the front mark column 5 and the back mark column 6 are shifted by a half pitch in the left-right direction in FIG. 4, the back mark column 6 is, for example, the middle of the arrangement of the timing marks for detecting the mark column on the front surface. Therefore, erroneous detection due to bleeding from the back side can be prevented. If the front mark column 5 and the back mark column 6 are shifted by a half pitch in the vertical direction in FIG. 4 as well, even if there is a timing mark detection deviation due to dirt or erroneous entry, it is more desirable. .

Although not shown, the entire amount mark portion shown in FIG. 3 is arranged so that the front surface and the back surface do not overlap each other, and the other surface of the surface having the mark column is arranged as an empty area. Similarly, it is possible to prevent erroneous detection of the mark due to blurring of the entry mark. However, in this case, the area that can be effectively used as the mark entry portion of the voting card is reduced due to the empty area.

A card identification mark 2 is printed on each of the first timing mark and the last timing mark.

The mark position table 14 is shown in FIG.
The data structure is as shown in FIG. 3, and the position information for specifying the position of the mark column for which it is necessary to detect the presence or absence of the mark is stored. This mark position table 14
Is provided for each card identification code obtained from the card identification mark 2 for identifying the type of voting card and the front surface and the back surface.

The mark detection unit 13 shown in FIG. 1 detects the presence or absence of a mark at the position of the card identification mark 2 of the voting card from the read image of the voting card, and the mark portion (black) is "1", The part without a mark (ground color of voting card) is set to "0" and coded into a code including 12-bit valid information to obtain a card identification code. The mark position table 14 prepared in advance is referred to by this card identification code. As shown in FIG. 10B, the mark position table 14 stores the number of mark columns for which the presence or absence of a mark should be detected and the position of the mark column for each column of timing marks.

In the mark position table 14, for example, in the case of the column C1, there are two mark columns for which the presence or absence of a mark should be detected, and the positions thereof are from the tip of the timing mark 7 of the column C1 to the mark column for each mark. Distance (Y1,
Y2) and the height of the mark field (H1, H2), the mark detection unit 13 determines the width of the mark reading area of the column C1 by the length of H1 which is separated from the tip of the timing mark 7 by the distance Y1. The presence / absence of the mark may be detected only in the range of the length and the range of the length of H2 separated by the distance Y2. For column C2, distance Y3, height H
The presence / absence of a mark is detected only in one mark column of 3.

Since the mark column for detecting the presence / absence of a mark is 0 for the column C3, the presence / absence of a mark is not detected for the column portion of the column C3.
Proceed to detection for the next column C4.

FIG. 11 is a processing flowchart of the voting card reading unit used in the embodiment of the present invention. In step S1, it is determined whether the mark position table 14 is necessary. If the mark position table 14 has already been set, it is unnecessary and thus step S2 is skipped. If the mark position table 14 is necessary, the mark position table 14 is loaded from the control unit 51 of FIG. 5 or the control unit 80 of FIG. 8 in step S2.

In step S3, the voting card inserted from the batch insertion section 46 or the single sheet insertion section 62 (FIG. 7) is
The sheet is conveyed toward the first surface reading unit 11 and the second surface reading unit 12. It should be noted that the following steps S4 to S15 are executed independently for each of the front surface and the back surface of the voting card.

In step S4, the first surface reading unit 1
The leading edge detection process of the voting card in each of the first and second surface reading units 12 is performed. This tip detection processing will be described later with reference to FIG. When the front surface of the voting card is detected by the first surface reading unit 11 or the second surface reading unit 12, the image of the voting card is optically detected by the first surface reading unit 11 or the second surface reading unit 12 in step S5. To read. In step S6, the timing mark 7 is detected from the read image. In addition,
The detection process of the timing mark 7 can be started in parallel with the reading of the image once the reading of the image is started without waiting for the completion of the reading of the entire image.

In step S7, it is determined whether the voting card is in the forward direction or the backward direction depending on whether the detected timing mark 7 is below or above the image of the voting card. If the voting card is in the forward direction, the process of step S8 is performed, and if the voting card is in the reverse direction, the process of step S10 is performed.

In step S8, the card identification mark is analyzed from the image of the voting card in the forward direction to obtain the card identification code. In step S9, the mark position table 14 corresponding to the card identification code is selected.

In step S10, the card identification mark is analyzed from the image of the voting card in the reverse direction to obtain the card identification code. In step S11, the mark position table 14 corresponding to the card identification code is selected. Since the mark position table 14 corresponding to the card identification code is selected in step S9 or step S11, regardless of whether the read voting card image is the front surface or the back surface, the correct mark is uniformly applied in the following processing. It will be possible to perform mark detection for the position.

In step S12, the process of detecting the timing mark 7 indicating each column C1, C2, ... From the image of the voting card is performed. If the timing mark 7 is detected, in step S13, the mark position table 1
4, it is determined whether or not there is a mark field for which the presence or absence of a mark should be detected in the corresponding column. If there is a mark column whose presence or absence of a mark is to be detected, the process of step S14 is performed, and if there is no mark column, the process proceeds to step S15.

In step S14, the presence or absence of a mark is detected in the mark columns of the number designated in the mark position table 14. In step S15, it is determined whether the column is finished. If an unprocessed column remains in the mark position table 14, the process returns to step S12 and the mark detection is repeated. When all the columns are finished, the process of step S16 is performed.

In step S16, it is determined whether or not the mark detection has been completed for the two surfaces, the front surface and the back surface. If the mark detection processing has been completed for the two surfaces, the process proceeds to step S17, and the read data is controlled to issue a ticket. And then the process ends.

FIG. 12 is a view for explaining the card edge detection processing in the voting card reading unit. Front side reading part 1 of voting card reading unit
1, the second surface reading unit 12, the image sensor 120
Are provided in the direction perpendicular to the conveyance direction of the mark sheet 1, and when the output signal of the image sensor 120 of 4 bits or more out of the specific 8 bits of the upper and lower portions corresponding to the width of the mark sheet 1 changes. , Judge as the leading edge of the mark sheet 1. By detecting the leading edge, the image of the mark sheet 1 is binary-input.

FIG. 13 is an explanatory diagram of timing mark detection. Here, the right direction is the X direction and the upper direction is the Y direction. The position of the timing mark 7 in the X direction is detected with 8 bits in the width of 2 bytes of the area where the timing mark 7 exists because the center of the timing mark 7 is not on the byte boundary. The starting point A0 is 8 at the timing mark detection position.
Six or more bits out of the bits are points in the X direction from white pixels to black pixels. Further, the end point A1 is a point where 6 bits or more out of 8 bits at the timing mark detection position are changed from black pixels to white pixels.

In order to obtain the position of the upper end of the timing mark 7 in the Y direction, the X direction is a width that is two pixels inside the width X0 of the timing mark 7, and the Y direction is upward from the lower end of the timing mark detection position. Consider an area S1 having a height of 24 bits, and project the data for this area S1 in the Y direction. In this projection data, the upper end of black is the front end B0 of the timing mark 7 in the Y direction. A4
Is the intersection of the tip B0 of the projection data in the Y direction and the start point A0 of the timing mark 7 in the X direction.

FIG. 14 is an explanatory diagram of the mark reading process after the timing mark is detected. In FIG. 14, A4
Is the same as A4 shown in FIG. 13 (the intersection of the tip B0 in the Y direction and the starting point A0 in the X direction). Y1 is the number of bits from A4 to the tip of the mark area, and is a value registered in the mark position table 14. Also, H1 is
It is the number of bits of the mark height, which is also a value registered in the mark position table 14. In reading the mark (detecting the presence or absence of the mark), the mark area is obtained from the position of the timing mark 7 in the X direction and the mark position table 14, and the height of the entry mark having the black pixel value is obtained by the projection process in the Y direction. Find My. When My is equal to or greater than the specified value, it is determined that a mark is present.

As described above, according to the present invention,
It is possible to prevent a reading error due to blurring of the entry mark when inputting from both sides of the mark sheet, and it is possible to improve the reliability of ticketing. Further, it is possible to correctly and quickly detect the mark regardless of the direction in which the mark sheets written on both sides are input. Further, by detecting the presence / absence of a mark only in a necessary mark field, it becomes possible to detect the mark in a short time and speed up the ticket issuing process.
