Abstract

PURPOSE:To reduce a read error and to easily distinguish a regular mark from an unauthorized mark by setting one or more linear print parts so that their PCS values can be set less than 0.2 and setting the PCS values of remaining linear print parts at >=0.4. CONSTITUTION:The PCS value defined in the following equation of the linear print part 6 for reading on one side is set at >=0.4, preferably, at >=0.7. The PCS value=(Rw-Rp)/Rw, where, the Rw represents the reflectance of a plane or a curved surface on which the linear print part is printed, and the Rp represents the reflectance of the linear print part. Also, the linear print part 8 for passing on the other side is set so that its PCS value can be set at <=0.2. In a general bar coder reader which reads the information of a bar code based on the difference of light reflectance by using an infrared ray sensor, etc., it is impossible to distinguish information clearly when the PCS value is set within a range A of 0.2-0.4, and it is feared that the linear print part 6 for reading to be read originally is not read, the that the linear print part 8 for passing not to be read originally is read.

Description

[Detailed Description of the Invention] 1 Ram Anti-Tori Momme I The present invention relates to a simple barcode attached to a ticket, etc. used as an admission ticket to an amusement park, etc., and more specifically, the present invention relates to a simple barcode attached to a ticket used as an admission ticket for an amusement park, etc. Regarding simple barcodes.

, Ming's technical background and its problems Traditionally, admission tickets for amusement parks, shrines and temples, tickets for rides such as ropeways, meal tickets for company cafeterias, and other tickets (hereinafter referred to as "tickets") were When entering, boarding, or exchanging tickets, a used ticket is manually marked to prevent the ticket from being used again.

However, manually marking tickets with performance markings (hereinafter referred to as "ticket checking") is extremely complicated, and in some cases, fraudulent tickets may not be recognized as genuine tickets. There was a risk of misidentification, and it was desired to save labor in this work. Particularly in today's world where regular photocopiers and color photocopiers have become widespread, by copying tickets, it is possible to easily produce tickets that are exactly the same as genuine tickets, making it possible to distinguish between genuine tickets and fraudulent tickets. It is difficult to distinguish between the two. In order to solve this inconvenience, it may be possible to create tickets using complicated printing technology and to create tickets that cannot be easily copied, but this would increase the cost of manufacturing tickets.
It was economically unfavorable.

On the other hand, in order to automate ticket gates by machine, it is necessary to determine whether a ticket is genuine by using a sign on the ticket. is preferred. this is,
This is because the groove structure of the reader for reading the sign can be simplified, costs can be reduced, and there are fewer reading errors. However, if the sign is made to have a simple structure, it is inconvenient that it becomes difficult to distinguish between a genuine ticket and a fraudulent ticket that has been copied using a copy machine.

Purpose of the Invention The present invention has been made in view of the above-mentioned circumstances, and is mainly attached to tickets etc. as a sign for automatic ticket gates.Although the structure is simple and there are few reading errors, the present invention is not a regular sign. The purpose of the present invention is to provide a simple barcode that can be easily distinguished from unauthorized signs.

SUMMARY OF THE INVENTION In order to achieve the above object, the barcode according to the present invention has at least two or more linear printed portions extending in the vertical direction of a flat or curved surface and having approximately the same width in the horizontal direction, which are approximately parallel to each other in the horizontal direction. At least 1 or more 6jJ line foreshadowing printing is set so that the PCS value defined by the following formula [Engine] is 0.2 or less, and the remaining linear printing part is printed on the PCS.
It is characterized in that the S value is set to be 0.4 or more.

PCS value = (Rw - RD) /Rw...
[I] (However, Rw is the reflectance of the flat or curved surface on which the linear printed portion is printed, and Rp is the fouling rate of the linear printed portion.) According to the barcode according to the present invention, the When such a simple barcode is used as a ticket gate sign, etc., the sign has a simple structure, so it can be easily and reliably read by a simple and inexpensive barcode reader, and the ticket gate It becomes possible to easily automate the process, contributing to labor saving. Moreover,
Although the structure of a simple barcode as a sign is simple and necessary, when a ticket, etc. containing the barcode is copied using a copy machine, the linear printing part is copied regardless of the PCS value, and all linear printing is The parts become the same PCS (a), and a barcode reader can easily distinguish between an unauthorized simple barcode and a legitimate simple barcode.

DETAILED DESCRIPTION OF THE INVENTION The present invention will now be described in detail with reference to embodiments shown in the drawings.

FIG. 1 is a plan view of a ticket with a simple bar code according to an embodiment of the present invention, and FIG. 2 is a graph showing the effect when the same ticket itself is read with a barcode reader. Figures (B) and (C) are graphs showing the effect when a copy of the same ticket is read by a barcode reader, and Fig. 3 is a graph showing the effect of the barcode reader.

As shown in FIG. 1, in this embodiment, a simple barcode 4 according to the present invention is printed on the surface of the ticket 2. The ticket 2 may be an admission ticket to an amusement park, a shrine or temple, a ticket to a vehicle such as a ropeway, a meal ticket to a company cafeteria, or any other ticket. Simple barcode 4 is
The ticket 20 consists of a plurality of linear printed parts 6 and 8 extending in the vertical direction of the front surface and having substantially the same width in the horizontal direction. Linear printing part 6
In this embodiment, a total of seven 8° are arranged parallel to the lateral direction of the front surface of the ticket 2 and at approximately equal intervals.

One of the lead linear printing parts 6 has a PCS value defined by the following formula [Equation] set to 0.4 or more, preferably 0.7 or more.

PCS value = (Rw - Rp) /Rw...
[I] (However, Rw is the reflectance of the flat or curved surface on which the linear printing section is printed, and Rp is the fouling rate of the linear printing section.) In this way, the PCS value of the linear printing section 6 for lead is calculated. To make it 0.4 or more, preferably 0.7 or more, for example, the surface of the ticket 2 should be yellow, white, or another light color, and the lead linear printing part 6 should be made of black whose main component is carbon black. It may be formed by printing with ink. The other path linear printing unit 8 is set so that the PCS value defined by the formula [I] is 0.2 or less.

In order to make the PCS value of the pass linear printing part 8 0.2 or less, for example, when the front surface of the ticket 2 is yellow, white, or other light color, the pass linear printing part 8 must be , it can be formed by printing the three primary colors one on top of the other with ink constituting each of the three primary colors. Alternatively, it is also conceivable to form the pass linear printed portion 8 in one printing using a black mixed ink that is a mixture of inks constituting each of the three primary colors in advance. In any case, the obtained linear printed part 8 for the path has the same black color as the linear printed part 6 for the lead, so that it is difficult to distinguish between these printed parts 6 and 8 during installation. It has become.

For example, the following inks are used as the inks constituting the three primary colors. As a yellow ink, Fast Yellow 01 Fufustoe [Knee 1-10G.

Printing inks containing pigments such as benzidine yellow are used; printing inks containing pigments such as ultramarine, navy blue, and phthalocyanine blue are used as blue inks; Gment Scarlet 3B.

Printing inks containing pigments such as Brilliant Cardin 6B, Regired C, Permanent Red 4R, Watching Red) and Brilliant Fast Scarlet are used.

The reason why the PCS value of the linear printing section 6 for reading is set to 0.4 or more, preferably 0.7 or more, and the PCS value of the linear printing section 8 for pathing is set to 0.2 or less is to read the barcode for reading these. This is necessary because the characteristics of the machine generally have the characteristics shown in Fig. 3.

In other words, as shown in Fig. 3, in a general barcode reader that uses an infrared sensor or the like to read barcode information based on the difference in light reflectance, the PCS value is 0.2.
In the range A of ~0.4, the information cannot be clearly distinguished, and there is a risk that the read linear print section 6, which should be read, may not be read, and the path linear print section 8, which should not be read, may not be read. This is because there is a risk that it may be read. Therefore, the PCS value of the lead linear printing section 6 should be set to 0.4 or more.
It is preferably 0.7 or more, and the PC of the path linear printing section 8
By setting the S value to 0.2 or less, a general barcode reader reliably reads only the read linear print section 6 and does not read the path linear print section 8.

According to the simple bar code 1-4 according to the present embodiment, when such a simple bar code 4 is used as a ticket gate sign etc. in the ticket 2, the structure of the sign is simple, so In addition, the signs can be read easily and reliably using an inexpensive barcode reader, making it easier to automate ticket gates and contributing to labor savings. Moreover, although the configuration of the simple barcode 4 as a sign is simple, the ticket 2 containing the barcode 4
etc., is copied using a copy machine, the linear printed portion 6.8 is copied regardless of the PCS value, and all linear printed portions 6, 8 are copied.
have the same PCS value. For example, if you copy the J ticket shown in Figure 1 using a general black-and-white copy machine and read it with a barcode reader, the black-and-white copy machine uses ink containing carbon black as the main component for pitching. Therefore, as shown in FIG. 2(B), all the linear printed parts 6.8 are read. In addition, when the ticket 2 shown in FIG. line 1 tree printing part 6.8
becomes the same PCS value as the path linear print section 8, and as shown in FIG. 2(C), it becomes impossible to read all the linear print sections 6.8.

Therefore, as shown in Fig. 2 (A>), there is a difference in the signal from the signal read by a general barcode reader from the genuine ticket 2, making it difficult for the machine to clearly distinguish between the genuine ticket 2 and the duplicate ticket. This makes it possible to automatically and effectively prevent unauthorized use of tickets.

Note that the present invention is not limited to the embodiments described above, and can be variously modified within the scope of the present invention.

For example, in the embodiment described above, all the linear printing parts 6,
Although the lateral widths of 8 are made substantially the same, they are not limited to this, and may be varied in various ways. Furthermore, the intervals between the linear printed parts 6 and 8 do not need to be approximately equal, and can be varied in various ways. δ et al., a linear printing section 6 that constitutes the simple barcode 4;
, 8 or the total number are not particularly limited. Furthermore, in the above-described embodiment, the color of the lead linear printed section 6 and the path linear printed section 8 are substantially the same black, but the present invention is not limited to this. You can also choose different colors.

Further, the simple barcode according to the present invention is not limited to the ticket 2, but can be attached to the flat or curved surface of any product or article as a sign to display some information while preventing unauthorized use. Is possible.

As described in detail, according to the present invention, at least one or more linear printed portions constituting a simple barcode are printed on PC
S (Since iQ is set to be 0.2 or less, and the PCS value of the remaining linear print area is set to be 0.4 or more, the simple barcode structure is simple and there are no reading errors. Despite the small number of signs, it is now possible to easily distinguish between legitimate signs and fraudulent signs. For example, if such a simple barcode is attached to a ticket, etc.
This simple barcode can be used as a sign for automatic ticket gates, making it easy to save labor at ticket gates.
