Description

The present invention relates to a gaming machine that includes a control board and a board case that houses the control board and requires security measures.

Conventionally, in gaming machines such as pachinko machines and slot machines, control boards (main control boards and sub control boards) on which various parts such as CPU, RAM, and ROM for controlling the operation of the gaming machines are mounted are made of synthetic resin. It is housed inside a sex substrate case.

However, there is a risk of fraudulent acts in which the board case is pried open and the board is replaced with an illegal one, and the prize balls and medals are paid out with a probability higher than a predetermined probability. In order to counter such fraudulent activities, for example, in the gaming machine described in Patent Document 1, a unique QR code (registered trademark) for identifying whether or not the control board is a legitimate control board is provided on the control board. ..

JP-A-2019-13317 (see paragraphs 0080-0089, etc.)

However, the disclosure content of Patent Document 1 enables a legitimate worker to read a QR code (registered trademark) provided on a control board using a reader without erroneous recognition, and is a fraudulent act. It does not prevent unauthorized reading of the QR code (registered trademark) by a person.

By the way, there may be a plurality of QR codes (registered trademarks) that can be visually recognized from the outside of the board case that houses the control board. In such a case, a cheating person may have some QR codes (registered trademarks). It seems that making it difficult to obtain information illegally is effective as a countermeasure against fraud.

The present invention has been made in view of the above problems, and when there are a plurality of codes that can be visually recognized from the outside of the board case that houses the control board, a fraudster illegally acquires information from some of the codes. It is an object of the present invention to provide a game machine in which the security of a part of the code is improved.

In order to achieve the above object, the gaming machine according to the present invention is a gaming machine including a control board and a board case for accommodating the control board, which is visible from the outside of the board case and can read information. It has a first-class code and a second-class code for which a reader is used, and the first-class code is created so that the brightness of the foreground color is lower than the brightness of the background color. The type 2 code is created so that the lightness of the foreground color is higher than the lightness of the background color, and the type 1 code created based on the first information is subjected to a predetermined decoding process. By performing the above, the first information can be recognized, and the second type code created based on the second information can recognize the second information even if the predetermined decoding process is performed. It is characterized in that the second information can be recognized by performing the predetermined decoding process and the specific decoding process.

Here, a code created with a foreground color lightness lower than a background color lightness is more commonly used than a code created with a foreground color lightness higher than the background color lightness. Therefore, a reader capable of reading information by performing a predetermined decoding process on a code created in which the brightness of the color of the foreground is lower than the brightness of the color of the background is widespread.

According to this configuration, the Type 2 code is created so that the lightness of the foreground color is higher than the lightness of the background color, which is higher than the commonly used background color lightness. Foreground color lightness is lower Since the relationship between the foreground color lightness and the background color lightness is reversed from the first-class code created, the foreground color lightness is higher than the background color lightness. In a reader designed for a low-creation Type 1 code or software built for a Type 1 code mounted on a reader, the foreground color brightness is better than the background color brightness in the first place. It is not possible to normally perform a predetermined decoding process on the second type code created with a high value. Further, in the second type code, in order to recognizable the second information, the predetermined decoding process is not enough and the predetermined decoding process and the specific decoding process are required. Therefore, the second type code is assumed to be normal. Even if the first decoding process can be performed, only mysterious information that cannot recognize the second information before the specific decoding process is obtained, and the fraudster who does not know that the specific decoding process is required It is possible to abandon further attempts at unauthorized acquisition at the stage of seeing the mysterious information that cannot recognize the second information. As a result, it is possible to improve the security of the second type code.

Also, there are both Type 1 and Type 2 codes, and a reader designed for Type 1 codes that are more commonly used than Type 2 codes or software built for Type 1 codes. Because of the widespread use of readers with the above, it is possible to induce fraudsters to prepare a reader designed for Type 1 code or software built for Type 1 code. It is possible to improve the security related to the seed code.

Further, the number of the first-class codes may be larger than the number of the second-class codes.

According to this configuration, the number of Type 1 codes is larger than the number of Type 2 codes, so the fraudster is a reader designed for Type 1 codes or software built for Type 1 codes. It is possible to further induce the fraudster to prepare a reader in which the above is implemented, and thereby further improve the security related to the type 2 code.

(Main control board)
Next, the main control board 63 will be described.

The main CPU 61 mounted on the main control board 63 has various functions realized by executing a program stored in the ROM 67 and various functions realized by controlling the hardware.

The main CPU 61 is a game of any one of a plurality of gaming states included in the slot machine 1 depending on the type of the winning combination group (having one or a plurality of combinations as constituent combinations) and the winning / non-winning of the winning combination. The game of the slot machine 1 is controlled to the state.

Further, the main CPU 61 adjusts the payout rate (number of medals won ÷ number of inserted medals × 100 [%]) based on a predetermined setting change operation for the power switch 50, the change processing start switch 56, and the reset switch 52. (Settings 1 to 6) are changed.

Further, the main CPU 61 selects one winning combination lottery table from a plurality of winning combination lottery tables based on the controlled game state type and the set setting values (settings 1 to 6). In this combination lottery table, for each of the plurality of preset winning combination groups, the winning combination group and the range of the lottery value at which the winning combination group wins the combination lottery are stored in association with each other.

Further, when the start switch 19 is operated by the player, the main CPU 61 generates a random number for the combination lottery within a predetermined range, and the generated random number value is used as the lottery value at the timing when the start switch 19 is operated. Extract. Then, the main CPU 61 determines whether or not the winning combination group is won by using the selected combination lottery value table and the extracted lottery value.

Further, when the start switch 19 is operated by the player, the main CPU 61 starts the rotation of each reel 13L, 13M, 13R, and the detection signals of the left / middle / right position sensors 55L, 55M, 55R and the left / The rotation positions of the left, middle, and right reels 13L, 13M, and 13R are detected based on the number of supply pulses to the reel motors 14L, 14M, and 14R that drive the middle and right reels 13L, 13M, and 13R, respectively. The main CPU 61 is in a state of accepting the operation of each of the stop switches 21L, 21M, 21R as an effective operation when all the reels 13L, 13M, 13R rotate at a constant speed. When the player operates the stop switches 21L, 21M, 21R in this state, the main CPU 61 determines the detected rotation positions of the left, middle, and right reels 13L, 13M, and 13R, and the stop switches by the player. Based on the operation mode of 21L, 21M, 21R (for example, push order and operation timing) and the winning combination lottery result, each reel is within a preset number of sliding frames (retractable range: usually, maximum 4 frames). Stop control is performed so that 13L, 13M, and 13R stop.

After all the reels 13L, 13M, 13R have stopped rotating, the main CPU 61 has a symbol combination in which the symbol combinations of the winning lines of the reels 13L, 13M, 13R correspond to the combinations that constitute the winning combination group won by the combination lottery. If the symbol combination of the winning line is a symbol combination corresponding to the winning combination, it is determined that the winning combination has been won, and if not, it is determined that the winning combination is lost. When the main CPU 61 determines that a winning combination has been won by a winning combination lottery, if it is a winning combination with a medal payout, the hopper unit 43 is operated to win the winning combination. The corresponding number of medals are paid out. However, if the number of credit medals stored has not reached the upper limit (for example, 50 in this embodiment), the main CPU 61 increases the number of credit medals by the number of payouts.

Further, the main CPU 61 switches between medal acceptance and non-acceptance by controlling the operation of the medal selector 48.

Further, the main CPU 61 is set, a game state, information on a combination lottery result, information on a symbol determination result, a rotation / stop state of each reel 13L, 13M, 13R, a medal payout state, and an opening or closing of the front door 5. Various information such as data representing the state of the slot machine 1 such as the state and the error state of the slot machine 1, information on the operation of the operating equipment operated by the player such as the stop switches 21L, 21M, 21R, and the start switch 19. A command for transmission to the sub control board 73 (sub CPU 71) is generated, and the generated command is transmitted to the sub CPU 71 of the sub control board 73. The command is transmitted from the main control board 63 to the sub control board 73 in one way.

(Sub control board)
Next, the sub control board 73 will be described. The sub control board 73 receives a command transmitted from the main control board 63, and performs an effect according to the operation and state of the main control board 63. The sub CPU 71 mounted on the sub control board 73 has various functions realized by executing a program stored in the memory 75 and various functions realized by hardware.

The sub CPU 71 receives commands including various data transmitted by the main control board 63 (main CPU 61). Then, the sub CPU 71 determines the content of the effect according to the received command, and according to the content of the determined effect, for example, performs display control for displaying an image such as a moving image on the liquid crystal display 27, or a speaker. The output of the sound from the 31L and 31R is controlled, and the light sources of the upper lamp unit 33 and the lower lamp unit 37L and 37R are controlled to blink all at once or individually.

Corresponds to "code".

(Caulking recording paper)
Subsequently, the caulking recording paper 350 will be described with reference to FIG.

The caulking recording paper 350 is formed of a light-transmitting sheet, and as shown in FIG. 6, each corner of the outer circumference of the caulking recording paper 350 is chamfered with an R0.3 mm, for example. Here, it is desirable that the caulking recording paper 350 is formed of a resin such as polyethylene terephthalate (PET) and is uncolored.

The caulking recording paper 350 is formed with characters related to the regular opening history of the substrate case 80. Here, as shown in FIG. 6, the characters related to the regular opening history of the board case 80 are "main board number", "caulking use record", "A", "B", "C", "F", The characters are "use", "main body fixing", "on-site inspection", "board recovery", "date", and "person in charge". Here, "A", "B", "C", and "F" are circled as shown in FIG. 6, but in the present specification, they are simply "A", "B", and "C". , "F".

Further, the color of the characters related to the regular opening history of the substrate case 80 formed on the caulking recording paper 350 is the background color of the main control board 63 (for example, the mounting facing the caulking recording paper 350 on the surface of the main control board 63). A color having a high contrast with respect to the ground color of the surface 63a) is used.

Further, the color of the frame line W1 along the outer circumference of the caulking recording paper 350 and the color of the frame line W2 that divides the characters related to the above-mentioned regular opening history of the substrate case 80 by vertical lines and horizontal lines are also formed on the caulking recording paper 350. For the background color of the main control board 63 (for example, the background color of the mounting surface 63a facing the caulking recording paper 350 among the surfaces of the main control board 63) as well as the color of the characters related to the regular opening history of the substrate case 80. , High contrast colors such as white are used. The frame line W1 is formed by a thicker line than the frame line W2.

Further, the caulking recording paper 350 includes a light transmitting portion having light transmission and a coloring portion 351 formed with a base color of a white color. Here, since the crimping recording paper 350 is formed of a sheet having light transmission, the light transmitting portion includes characters and borders W1 related to the normal opening history of the substrate case 80 formed on the colored portion 351 and the recording paper 350. It is a part other than W2.

The coloring unit 351 includes a plurality of areas, for example, a character area 354 in which character information 354a is described, a code area 355 in which a QR code (registered trademark) 355a is described, a stamp area 357, and a date entry. A total of nine areas, the area 356a and the person in charge name entry area 356b, are provided, and the colored portion 351 is colored in a rectangular shape, and is white in the present embodiment.

The letter "A" is formed in white on the left side of the stamping area 357 provided on the upper right of the caulking recording paper 350 as described above. Here, the marking area 357 on the upper right of the caulking recording paper 350 is an area capable of being imprinted indicating that the “A caulking portion” has been used. Here, the engagement between the cover member 80a and the base member 80b is defined as "A caulking", and the portion of the substrate case 80 to which "A caulking" is applied is defined as "A caulking portion". The “A caulking part” is inside the board case 80 from the time when the slot machine 1 is shipped from the manufacturing factory until the inspection organization of the slot machine 1 opens the board case 80 and inspects the main control board 63. This is a portion for sealing the substrate case 80 so that the main control board 63 is not tampered with, and a trace thereof remains when the substrate case 80 is illicitly opened. The stamping area 357 is not limited to the stamping, and the stamping area 357 may be filled with a writing tool or the like.

"Date" is on the upper side of the top date entry area 356a, "person in charge" is on the upper side of the top person name entry area 356b, and "person" is on the left side of the top date entry area 356a. "B" and "for fixing the main body", "C" and "on-site inspection" on the left side of the central date entry area 356a, and "F", "for board collection" on the left side of the bottom date entry area 356a The letters of are formed in white as described above.

Here, the characters "B" and "for fixing the main body" formed on the caulking recording paper 350 are "B caulking part" in which the date entry area 356a and the person in charge name entry area 356b on the same line normally use "B caulking part". Indicates that the area where the "date" can be entered by handwriting or stamping with the worker's writing instrument and the area where the name of the "person in charge" who normally uses the "B caulking part" can be entered with the writing instrument. There is. Here, the engagement between the support plate 81 and the substrate case 80 is defined as "B caulking", and the portion of the substrate case 80 to which "B caulking" is applied is defined as "B caulking portion". The "B caulking portion" is formed by connecting the board case 80 to the support plate 81 so that the board case 80 is not illegally removed from the support plate 81 after the slot machine 1 is shipped from the manufacturing factory. Is a part for leaving a trace when the support plate 81 is illegally removed. When inspecting the board case 80 and the support plate 81, whether or not the board case 80 has been illegally removed from the support plate 81 by checking the "B caulking portion" and its surroundings (presence or absence of destruction marks, etc.). Can be confirmed.

In addition, the characters "C" and "on-site inspection" formed on the caulking recording paper 350 are "years and months" in which the date entry area 356a and the person in charge name entry area 356b on the same line normally use the "C caulking part". It indicates that the area where the "day" can be entered with a writing tool or the like and the name of the "person in charge" who normally uses the "C caulking part" can be entered with a writing tool or the like. Here, the engagement between the support plate 81 and the substrate case 80, which is a spare of the “B caulking” and after the B caulking portion is destroyed for inspection, is defined as “C caulking”, and is defined as “C caulking” in the substrate case 80. The part to which "C caulking" is applied is defined as "C caulking part". A "D caulking" may be further provided as a spare for the "C caulking".

The letters "F" and "for substrate recovery" formed on the caulking recording paper 350 are "years" in which the date entry area 356a and the person in charge name entry area 356b on the same line normally use the "F caulking part". It indicates that the area where the "month and day" can be entered with a writing tool or the like and the area where the name of the "person in charge" using the "F caulking part" can be entered with a writing tool or the like. Here, when the main control board 63 is returned to the manufacturer, engaging the base member 80b and the cover member 80a in the board case 80 accommodating the main control board 63 is defined as "F caulking", and the board is defined as "F caulking". The portion of the case 80 where the "F caulking" is applied is defined as the "F caulking portion". The "F caulking portion" seals the board case 80 so that the board case 80 is not illegally opened when the main control board 63 is returned to the manufacturer, and when the board case 80 is illegally opened. Is the part to leave the trace.

Further, the character information 354a is, for example, a management number of a main control board (main board) such as "ABCD / 12345".

In the following, the code processing for converting a character string consisting of, for example, alphanumeric characters and symbols into a QR code (registered trademark) will be appropriately described as "first code processing". Further, the decoding process for converting the QR code (registered trademark) into the character string used for creating the QR code (registered trademark) is appropriately described as "first decoding process", and the "predetermined decoding process" of the present invention. Corresponds to.

Further, the QR code (registered trademark) 355a is obtained by processing a first character string (corresponding to the "first information" of the present invention) composed of, for example, alphanumeric characters and symbols, and coloring the result in white. It was created by printing or the like in black on the colored portion 355. The QR code (registered trademark) 355a is a first-class QR code (registered trademark) having a black foreground and a white background.

The first character string is read by a legitimate worker from the QR code (registered trademark) 355a and used for confirmation work. In the first embodiment, the first character string is information that can identify the character information 354a, but is not limited to this. Here, the information that can identify the character information 354a is information that completely matches the character information 354a or information that can specify the character information 354a even if it does not completely match the character information 354a. Information that can identify the character information 354a even if it does not completely match the character information 354a is, for example, ABCD12345 (without slash) when the character information 354a is ABCD / 12345, and ABCD when the character information 354a is ABCD12345. -12345 (with hyphen), ABCD / 12345 (without "s") when the character information 354a is ABCD / 12345s ("s" is added regardless of the model), and the character information 354a is ABCD / 12345. 12345 / ABCD (replacement of order) in some cases, 006453 when character information 354a is 6453 (with "00" (upper digit) on the upper digit side), K6453 (upper digit) when character information 354a is 6453 There is "K" on the side), K006453 when the character information 354a is 6453 (there are "K" and "00" on the upper digit side), and the like. Further, even if there is a difference between uppercase and lowercase letters, a difference between full-width and half-width characters, a difference in font, etc., the information that can identify the character information 35ab even if it does not exactly match the character information 354a. It may be included in one example.

In the QR code (registered trademark) 355a, a reader is used to image the QR code (registered trademark) 355a with the camera provided by the reader, and the QR code (registered trademark) 355a is imaged by the CPU or the like provided with the reader. The first character string is obtained by detecting the cutout symbol and performing the first decoding process corresponding to the first code process based on the positional relationship between the foreground and the background with respect to the cutout symbol. By this first decoding process, for example, a person such as a legitimate worker can recognize all of the first character string. Therefore, for example, a legitimate worker can perform the confirmation work using all of the first character strings recognizable by the first decoding process from the QR code (registered trademark) 355a.

(Seal seal)
Subsequently, the sealing seal 550 will be described with reference to FIG. 7.

The rectangular sealing sticker 550 is formed of a white sheet having a lower light transmittance than the light transmitting portion of the caulking recording paper 350, and as shown in FIG. 7, each corner of the outer periphery of the sealing sticker 550 has, for example, R2 mm. It is chamfered and the like, and the character information 550b and the QR code (registered trademark) 550a are displayed.

The character information 550b is, for example, the serial number of the sealing sticker 550 such as "876554321" or "D22594939".

Further, the QR code (registered trademark) 550a processes a second character string (corresponding to the "first information" of the present invention) composed of, for example, alphanumeric characters and symbols as the first code, and the result is a seal seal 550. It was created by printing in black. The QR code (registered trademark) 550a is a first-class QR code (registered trademark) having a black foreground and a white background.

The second character string is read by a legitimate worker from the QR code (registered trademark) 550b and used for confirmation work. In the first embodiment, the second character string is information different from the character information 550a, but is not limited to this.

In the QR code (registered trademark) 550a, a reader is used to image the QR code (registered trademark) 550a with the camera provided by the reader, and the QR code (registered trademark) 550a is imaged by the CPU or the like provided with the reader. The result is a second character string by detecting the cutout symbol and performing the first decoding process corresponding to the first code process based on the positional relationship between the foreground and the background with respect to the cutout symbol. By this first decoding process, for example, a person such as a legitimate worker can recognize all of the second character string. Therefore, for example, a legitimate worker can perform the confirmation work using all of the second character strings recognizable by the first decoding process from the QR code (registered trademark) 550a.

(Model sticker)
Subsequently, the model seal 750 will be described with reference to FIG.

The rectangular model seal 750 is formed of a white sheet having no light transmission, and as shown in FIG. 8, each corner of the outer periphery of the seal seal 550 is chamfered with, for example, R1.5 mm. The model name 750a, the character information 750b, and the QR code (registered trademark) 750c are displayed, and the colored portion 750d colored in black such that the QR code (registered trademark) 750c is printed in white is formed.

The model name 750a is the model name of the slot machine 1.

Further, the character information 750b is, for example, a model number of a slot machine 1 such as "Y30A".

In the following, for example, a code process for converting a character string consisting of alphanumeric characters or symbols into another character string that cannot be recognized by a person is appropriately described as "second code process". Further, the decoding process for converting another character string into the character string used for creating the other character string is appropriately described as "second decoding process", and corresponds to the "specific decoding process" of the present invention.

Further, the QR code (registered trademark) 750c is obtained by processing a third character string (corresponding to the "second information" of the present invention) composed of, for example, alphanumeric characters and symbols, and obtaining the result of the second code processing. Another character string (hereinafter referred to as "intermediate character string") that the person who is not able to recognize the third character string is processed by the first code, and the result is printed in white on the colored portion 750d colored in black. It is formed by doing. The QR code (registered trademark) 750c is a second-class QR code (registered trademark) having a white foreground and a black background.

The third character string is read by a legitimate worker from the QR code (registered trademark) 750c and used for confirmation work. In the first embodiment, the third character string is information that can identify the character information 750b, but is not limited to this.

In the first embodiment, the intermediate character string obtained by processing the third character string in the second code is, for example, when the third character string consists of only an information portion capable of specifying the character information 750b (for example, "Y30A". ) Or a part of the information part that can identify the character information 750b (for example, "X ₁ X ₂ Y30AX ₃ "), a person such as a regular worker cannot recognize the third character string, and further The character information 750b constituting all or a part of the three character strings is a character string that cannot recognize identifiable information, and the second code processing is a processing for obtaining such an intermediate character string.

In the QR code (registered trademark) 750c, a reader is used to image the QR code (registered trademark) 750c with the camera provided in the reader, and the QR code (registered trademark) 750c is imaged by the CPU or the like provided in the reader. The result is converted into an intermediate character string by detecting the cutout symbol and performing the first decoding process corresponding to the first code processing based on the positional relationship between the foreground and the background with respect to the cutout symbol. The intermediate character string obtained as a result of the conversion is converted into a third character string by performing a second decoding process corresponding to the second code processing, whereby, for example, a person such as a regular worker can use the third character. All of the columns can be recognized. Therefore, for example, a legitimate worker can perform confirmation work using all of the third character strings recognizable from the QR code (registered trademark) 750c by both the first decoding process and the second decoding process. Will be able to do. Here, the first decoding process includes a first-class QR code (registered trademark) such as QR code (registered trademark) 355a, 550a and a second-class QR code (registered trademark) such as QR code (registered trademark) 750c. ), The character string before being coded (original character string) based on the positional relationship between the foreground and the background with respect to the cutout symbol by detecting the cutout symbol from the imaging result. Is for getting. However, a reader designed for a first-class QR code® with a white background and a black foreground or built for a first-class QR code® mounted on a reader. In the software, for example, the relationship between the foreground and background brightness is reversed between the first type QR code (registered trademark) and the second type QR code (registered trademark), so before the first decoding process is performed. The cutout symbol cannot be detected normally unless it has a function to recognize the relationship between the foreground color and the background color and a black-and-white inversion function, and it is normal for the second type QR code (registered trademark). The first decoding process cannot be performed. It was also constructed for a reader designed for a second-class QR code (registered trademark) with a black background and a white foreground, or for a second-class QR code (registered trademark) mounted on the reader. Similarly, the software cannot normally perform the first decoding process on the first type QR code (registered trademark).

However, with the QR code (registered trademark) 750c, even if the imaging result of the QR code (registered trademark) 750c is subjected to the first decoding process corresponding to the first code processing, only the intermediate character string that a person cannot recognize the third character string is available. I can't get it. That is, in the QR code (registered trademark) 750c, a person cannot recognize all of the third character string until the first decoding process.

In the first embodiment, there are two types of QR codes (registered trademark), QR codes (registered trademark) 355a and 550a, which can be visually recognized from the outside of the substrate case 80. There is one of the two types of QR codes (registered trademark), the QR code (registered trademark) 750c, and the former is more than the latter.

Therefore, according to the first embodiment described above, the second type QR code (registered trademark) 750c is created with a white foreground and a black background, and the generally widely used foreground is black. The first type QR code (registered trademark) 355a, 550a created with a white background is created with a black foreground and a white background because the relationship between the color brightness of the foreground and the background is reversed. In addition, in a reader designed for a first-class QR code (registered trademark) 355a, 550a, etc., or in software built for a first-class QR code (registered trademark) 355a, 550a mounted on a reader, In the first place, it is normal for the second type QR code (registered trademark) 750c created with a white foreground and a black background, for example, the cutout symbol cannot be found normally because the relationship of brightness is reversed. The first decoding process cannot be performed. Further, in the second type QR code (registered trademark) 750c, the first decoding process is not enough to recognizablely acquire the third character string used for the confirmation work, and the first decoding process and the second decoding process are performed. Because it is necessary, even if the first decoding process of the second type QR code (registered trademark) 750c can be performed normally, a mysterious character string that cannot be recognized by a person before the second decoding process is performed. I saw a mysterious character string (intermediate character string) that only (intermediate character string) can be obtained and that a person cannot recognize the third character string to a fraudster who does not know that the second decoding process is necessary. It is possible to abandon further attempts at fraudulent acquisition at the stage. As a result, it is possible to improve the security of the second type QR code (registered trademark) 750c.

In addition, there are both a first-class QR code (registered trademark) 355a, 550a and a second-class QR code (registered trademark) 750c, which are more commonly used than the second-class QR code (registered trademark) 750c. A reader designed for the first-class QR code (registered trademark) 355a, 550a or a reader equipped with software built for the first-class QR code (registered trademark) 355a, 550a is widely used. Therefore, prepare a reader designed for the first-class QR code (registered trademark) 355a, 550a or software built for the first-class QR code (registered trademark) 355a, 550a. It is possible to guide fraudsters and improve the security of the second type QR code (registered trademark) 750c.

In addition, since the number of the first type QR code (registered trademark) 355a and 550a is larger than the number of the second type QR code (registered trademark) 750c, the fraudster is the first type QR code (registered trademark). It is possible to more induce fraudsters to prepare a reader designed for 355a, 550a or a reader equipped with software built for a first-class QR code® 355a, 550a. , It is possible to further improve the security of the second type QR code (registered trademark) 750c.

<Second Embodiment>
The slot machine 1, which is an example of the gaming machine according to the second embodiment of the present invention, will be described with reference to FIGS. 9 to 13. FIG. 9 is an exploded perspective view of the main control board 63 and the board case 80 of the second embodiment. FIG. 10 is a front view of the substrate case 80 accommodating the main control substrate 63 attached to the support plate 81. FIG. 11 is a diagram showing an outline of a mounting surface 63a of the main control board 63 in the region surrounded by the alternate long and short dash line B in FIG. FIG. 12 is a diagram showing an outline of a cross section taken along the line AA of FIG.

In the second embodiment, the QR code (registered trademark) is mainly formed in the non-wiring region 2015 (the region where the wiring pattern surrounded by the first wiring pattern formed by solid wiring does not exist) on the mounting surface 63a of the main control board 63. ) 1000 is arranged, and the substrate case 80 is different from the first embodiment in that a recess 1030 is formed corresponding to the non-wiring region 2015. In the second embodiment, the same reference numerals are given to the same configurations as those in the first embodiment, and the description thereof will be omitted.

As shown in FIG. 12, the main control board 63 is housed in a board case 80 including a cover member 80a and a base member 80b.

In the main control board 63, on the mounting surface 63a, a wiring pattern 2010 for ground having a potential of 0, a wiring pattern for power supply having a potential of VDD (not shown), and a wiring pattern for signals 2020. Is arranged, and a plurality of parts such as the main CPU 61 and the connector 1020 are mounted (see FIGS. 11 and 12). The wiring pattern 2010 is formed of a single solid wiring. The details of the arrangement position of the connector 1020 will be described later.

Further, on the back surface 63b of the main control board 63, a wiring pattern 2030 for ground having a potential of 0, a wiring pattern for power supply having a potential of VDD (not shown), and a wiring pattern for signals (Not shown) is arranged (see FIG. 12).

Further, the main control board 63 has vias penetrating the main control board 63 that electrically connects the ground wiring pattern 2010 arranged on the mounting surface 63a and the ground wiring pattern 2030 arranged on the back surface 63b. A plurality of 2040 and 2045 vias are formed (see FIGS. 11 and 12). The details of the arrangement positions of the plurality of vias 2040 will be described later. Further, the main control board 63 has vias (not shown) penetrating the main control board 63 that connects the wiring pattern for the power supply arranged on the mounting surface 63a and the wiring pattern for the power supply arranged on the back surface 63b. Multiple are formed. Further, the main control board 63 has a plurality of vias 2050 penetrating the main control board 63 connecting the wiring pattern 2020 for signals arranged on the mounting surface 63a and the wiring pattern for signals arranged on the back surface 63b. It is formed (see FIG. 11). Each via such as the via 2040 has a color (for example, gold) that is significantly different from the color of the wiring pattern 2010 and the color of the mounting surface 63a.

Further, on the mounting surface 63a of the main control board 63, there is a non-wiring region 2015 in which the wiring pattern 2010 formed by a single solid wiring is surrounded, the size is larger than the size of the seal 1010, and no wiring pattern exists. However, the mounting surface 63a is exposed (see FIGS. 10, 11, and 12). In the second embodiment, the color of the wiring pattern 2010 and the color of the mounting surface 63a (the color of the non-wiring region 2015 in which the mounting surface 63a is exposed) can be distinguished, but similar colors that are difficult to distinguish at first glance (for example, , Green and dark green).

As shown in FIG. 11, the plurality of vias 2040 described above are laid in an aligned manner in an adjacent region adjacent to the non-wiring region 2015 in the wiring pattern 2010. In the specific example of FIG. 11, five vias 2040 are laid at substantially equal intervals in the upper region of the non-wiring region 2015 in the adjacent region, and 5 in the lower region of the non-wiring region 2015 in the adjacent region. The vias 2040 are laid at approximately equal intervals. As an example of arranging a plurality of vias 2040 in an adjacent area, it is possible to arrange and lay them so as to surround the entire circumference of the non-wiring town area 2015. As described above, the plurality of vias 2040 are absent in the wiring pattern 2010 so that the plurality of vias 2040 serve as a mark of the existence position of the non-wiring region 2015 when the operator attaches the seal 1010 to the non-wiring region 2015. It is preferable to arrange and lay them in the adjacent area adjacent to the wiring area 2015.

Further, a QR code (registered trademark) 1000, which is used by a reader when reading information, is formed on the front surface, and a sticker 1010 coated with an adhesive is formed on the back surface so that the entire sticker 1010 fits in the non-wiring region 2015. , Attached to the non-wiring area 2015 (see FIGS. 10, 11, and 12). In FIG. 10, the QR code (registered trademark) 1000 exists on the back side (positive direction side of the y-axis) of the substrate case 80, but is shown by a solid line for convenience of drawing. Since the non-wiring region 2015 is flat, the surface of the seal 1010 can be flattened without being uneven due to the sticker 1010 being attached to the non-wiring region 2015.

The QR code (registered trademark) 1000 is created by first processing a fourth character string consisting of, for example, alphanumeric characters and symbols, and printing the result on a white sticker 1010 in black.

The fourth character string is read by a regular worker from the QR code (registered trademark) 1000 and used for confirmation work. In the second embodiment, the fourth character string is the board ID of the main control board 63, but the manufacturing number, the manufacturing location, and the like are not limited thereto.

In the QR code (registered trademark) 1000, a reader is used to image the QR code (registered trademark) 1000 with the camera provided by the reader, and the QR code (registered trademark) 1000 is imaged by the CPU or the like provided with the reader. The fourth character string is obtained by detecting the cutout symbol and performing the first decoding process corresponding to the first code processing based on the positional relationship between the foreground and the background with respect to the cutout symbol. By this first decoding process, a person such as a legitimate worker can recognize all of the fourth character string. Therefore, for example, a legitimate worker can perform the confirmation work using all of the fourth character strings recognizable from the QR code (registered trademark) 1000 by the first decoding process.

The QR code (registered trademark) 1000 formed on the surface of the seal 1010 attached to the non-wiring region 2015 is obtained by processing the fourth character string as the second code and obtaining the result of the second code processing. 4 A QR code (registered trademark) formed by first code processing another character string that cannot recognize the character string and printing the result in white on the black colored part of the seal 1010. In the second embodiment, there are no restrictions on the type of QR code (registered trademark) 1000 or the like.

Further, as shown in FIG. 11, the connector 1020 is arranged in a region (hereinafter, referred to as “recessed forming facing region”) 2000 including the non-wiring region 2015 in the mounting surface 63a. The arrangement position of the connector 1020 hinders the discovery of the QR code (registered trademark) 1000 by, for example, a fraudster while the main control board 63 is housed in the board case 80, but the QR code by a legitimate worker with a reader It is preferable that the position does not interfere with the imaging of the code (registered trademark) 1000. Further, as will be described later, in the substrate case 80, a recess 1030 is formed in a region overlapping the recess forming facing region 2000 in the front view of the substrate case 80 accommodating the main control board 63, and the recess 1030 is a QR code in a perspective view. Since it has an effect of hindering the discovery of (registered trademark) 1000, it is preferable to set the size of the recess forming facing region 2000 based on this.

The front plate 80a1 of the cover member 80a of the board case 80 has a region that overlaps with the recessed facing region 2000 of the mounting surface 63a of the main control board 63 in the front view of the board case accommodating the main control board 63 (hereinafter, “recessed portion”). The recess 1030 is formed so that the “forming region”) has a concave shape recessed on the mounting surface 63a side of the main control board 63, and an insertion hole 1031 is formed in a part of the recess 1030 (referred to as a recess 1030). 9), 10 and 12). When the main control board 63 is housed in the board case 80, the connector 1020 is inserted into the insertion hole 1031.

The surface of the recess 1030 facing the mounting surface 63a of the main control board 63 is a flat surface parallel to the mounting surface 63a in the entire area of the surface. The surface of the recess 1030 facing the mounting surface 63a of the main control board 63 is at least a region overlapping the non-wiring region 2015 in the front view of the board case 80 accommodating the main control board 63, and is parallel to the mounting surface 63a. A flat surface is preferable.

In the second embodiment, the recess 103 is formed in a region of the mounting surface 63a that overlaps the recess-forming facing region 2000 when viewed from the front of the substrate case 80 accommodating the main control board 63. For example, it may be formed only in a region that does not overlap with the region other than the non-wiring region 2015, but overlaps with the non-wiring region 2015.

Further, the board case 80 accommodating the main control board 63 is attached to the rear side surface of the housing 3 of the slot machine 1 by the support plate 81, and the operating state of the slot machine 1 in which the main control board 63 is connected to the sub control board 73 or the like is formed. Then, as shown in FIG. 13, the harness H connected to the connector 1020 is fixed to the cover member 80a of the substrate case 80 with a clip or the like and laid so as to extend to the non-wiring region 2015 side. As an example in which the harness H extends to the non-wiring region 2015 side, as shown in FIG. 13, the non-wiring region is overlapped with the non-wiring region 2015 in the front view of the board case 80 accommodating the main control board 63. In addition to the case where the harness H extends to the 2015 side, for example, the harness H does not overlap the non-wiring area 2015 in the front view of the board case 80 accommodating the main control board 63, but overlaps the area near the non-wiring area 2015. It may extend to the non-wiring area 2015 side.

Therefore, according to the second embodiment described above, the sticker 1010 is attached by setting the region to which the sticker 1010 is attached as a non-wiring region 2015 in which the wiring pattern surrounded by the wiring pattern 2010 formed by solid wiring does not exist. Sometimes the area to which the sticker 1010 is attached can be made visually easy to understand. Further, the non-wiring area 2015 in which no wiring pattern exists is normally flat, and when the seal 1010 is attached to the normally flat non-wiring area 2015, the seal 1010 is attached to the non-wiring area 2015. As a result, the QR code (registered trademark) 1000 formed on the surface of the seal 1010 cannot be uneven, and therefore, the QR code (registered trademark) 1000 imaged when the QR code (registered trademark) 1000 is imaged by a reader ( The registered trademark) 1000 is hardly distorted, and erroneous recognition of the QR code (registered trademark) 1000 can be prevented. Further, since the sticker 1010 is attached to the flat non-wiring region 2015, the sticker 1010 is less likely to come off.

In addition, an area where there is no wiring pattern that is not surrounded by wiring patterns on all sides is created in order to enter the dicing margin and the board serial number, but a region where there is no wiring pattern that is not surrounded by wiring patterns on all sides is created. When the sticker 1010 is used as the sticking area, a step of creating a mark such as "" that makes it possible to distinguish the sticker area of the sticker 1010 by silk printing is required to prevent misidentification of both areas. However, in the second embodiment, the above-mentioned silk printing step is required by setting the area to which the sticker 1010 is attached as the non-wiring area 2015 in which the wiring pattern surrounded by the wiring pattern 2010 formed by solid wiring does not exist. Therefore, it is possible to suppress an increase in the manufacturing process.

Further, when viewed from the front of the substrate case 80, the QR code (registered trademark) 1000 has the entire QR code (registered trademark) 1000 in the depth of the flat region in the recess 1030 formed in the substrate case 80. Since they exist so as to overlap each other, the recesses 1030 of the substrate case 80 do not interfere with the imaging by the reader, and the QR code (registered trademark) 1000 can be easily imaged by the reader. Further, in the perspective of the substrate case 80, the QR code (registered trademark) 1000 is difficult to see due to the recess 1030 of the substrate case 80, so that the QR code (registered trademark) 1000 is located behind the recess 1030 formed in the substrate case 80. It is difficult for people who do not know QR code (registered trademark) 1000 to find it.

Further, since the wiring pattern 2010 and the non-wiring area 2015 are similar colors (for example, green and dark green), the boundary between the wiring pattern 2010 and the non-wiring area 2015 is difficult to understand, but the via 2040 is also non-wiring with the normal wiring pattern 2010. Since the colors are significantly different from those of the area 2015 and are conspicuous, the non-wiring area 2015, which is the area to which the seal 1010 is attached, is formed by the plurality of vias 2040 laid in the adjacent area adjacent to the non-wiring area 2015 in the wiring pattern 2010. It becomes easy to understand and the work of attaching the seal 1010 becomes easy. In particular, when the light hits the via 2040 and is reflected, the reflected light makes it easier to see the plurality of vias 2040 laid in alignment with the adjacent region, and the non-wiring region becomes easier to understand, so that the sticker can be attached. It will be easier.

Further, by providing the connector 1020 in the recessed facing region 2000, the QR code (registered trademark) 1000 becomes difficult to see due to the connector 1020, so that a person who does not know where the QR code (registered trademark) 1000 is located can use the QR code (registered trademark). ) It can be more difficult to find 1000.

Further, in the operating state in which the harness H is connected to the connector 1020, the QR code (registered trademark) 1000 is difficult to see due to the harness H laid so as to extend to the non-wiring area 2015 side, so that the QR code (registered trademark) It can make it more difficult for someone who does not know where the 1000 is to find the QR Code® 1000. Further, even if a fraudster can find the QR code (registered trademark) 1000, the harness H becomes an obstacle when the QR code (registered trademark) 1000 is imaged by the reader, and the QR code (registered trademark) is detected by the reader. Imaging of (registered trademark) 1000 can be made more difficult.

Further, for example, by providing an insertion hole 1031 through which the connector 1020 is inserted in the recess 1030 used for hiding the QR code (registered trademark) 1000 from a fraudulent person, a recess such as the recess 1031 in the substrate case 80 can be produced. The number can be reduced, and the substrate case 80 can be easily manufactured.

The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.

For example, in the first embodiment described above, it is assumed that the first type QR code (registered trademark) 355a, 550a has a white background and the foreground is black, and the second type QR code (registered trademark) 750c has a black background. The foreground is white, but the foreground is not limited to this, and the first type QR code (registered trademark) 355a, 550a is more foreground than the lightness of the background color except that the background is white and the foreground is black. The QR code (registered trademark) with lower color lightness is used, and the second type QR code (registered trademark) 750c is the lightness of the foreground color than the lightness of the background color except that the background is black and the foreground is white. May be a higher QR code (registered trademark).

Further, in the above-described first embodiment, the first type QR code (registered trademark) is two QR codes (registered trademark) 355a and 550a, and the second type QR code (registered trademark) is a QR code (registered trademark). ) 750c, but not limited to this, except that there are two QR codes (registered trademark) of the first type and one QR code (registered trademark) of the second type. The number of one type QR code (registered trademark) may be larger than the number of second type QR code (registered trademark).

Further, in the above-described first embodiment, the first type QR code (registered trademark) is two QR codes (registered trademark) 355a and 550a, and the second type QR code (registered trademark) is a QR code (registered trademark). ) However, it is not limited to one of 750c, and even if the number of the first type QR code (registered trademark) and the number of the second type QR code (registered trademark) are the same. Alternatively, the number of the second type QR code (registered trademark) may be larger than the number of the first type QR code (registered trademark).

Further, in the above-described first embodiment, a QR code (registered trademark) that can be visually recognized from the outside of the substrate case 80 is formed on the caulking recording paper 350, the sealing sticker 550, and the model seal 750 attached to the outer surface of the substrate case 80. The QR code (registered trademark) is 355a, 550a, 750c, but the present invention is not limited to this, and for example, the QR code (registered trademark) that can be visually recognized from the outside of the substrate case 80 directly engraved on the substrate case 80. ), Or a QR code (registered trademark) visible from the outside of the board case 80 provided on the mounting surface 63a of the main control board 63, or provided on the top surface of the electronic component mounted on the mounting surface 63a. It may be a QR code (registered trademark) that can be visually recognized from the outside of the board case 80.

Further, in the first embodiment described above, the intermediate character string obtained by processing the third character string in the second code is, for example, a case where the third character string consists of only an information portion capable of specifying the character information 750b (for example,). , "Y30A") or when a part of the information includes an information part that can identify the character information 750b (for example, "X ₁ X ₂ Y30AX ₃ "), a person such as a regular worker can recognize the third character string. However, the character information 750b constituting all or part of the third character string is a character string that cannot be recognized, and the second code processing is a process for obtaining such an intermediate character string. However, the present invention is not limited to this, and for example, the following may be used. For example, the intermediate character string obtained by processing the third character string in the second code is, for example, when the third character string includes an information part in which the character information 750b can be specified (for example, "X ₁ X _2"). Y30AX ₃ "), a person such as a regular worker cannot recognize the entire third character string, but can recognize information that can identify the character information 750b that constitutes a part of the third character string. It is a character string (for example, "Y ₁ Y ₂ Y ₃ Y ₄ Y ₅ Y30AY ₆ Y ₇ "), and the second code processing may be a processing for obtaining such an intermediate character string. In this way, for example, when the character information 750b and the QR code (registered trademark) 750c are arranged close to each other, a legitimate worker may use a reader or software implemented in the reader to perform QR. When trying to read the third character string from the code (registered trademark) 750c, the first decoding process for the QR code (registered trademark) 750c whose foreground is white and the background is black in the reader or the software installed in the reader. If the function of the above is provided but the function of the second decoding process is not provided, the entire third character string cannot be recognized, but the character information 750b is obtained from the intermediate character string obtained by the first decoding process. The identifiable information can be recognized, and the recognized character information 750b can be compared with the identifiable information and the character information 750b.

Further, in the first embodiment and the second embodiment described above, the two-dimensional code is QR code (registered trademark) 355a, 550a, 750c, 1000, but the present invention is not limited to this, and for example, QR. It may be a two-dimensional code other than the code (registered trademark), a one-dimensional code such as a barcode, or the like.

Further, in the second embodiment described above, the wiring pattern 2030 for the ground where the potential is a predetermined value 0 is provided in the non-wiring region 2015 where there is no wiring pattern to which the seal 1010 on which the QR code (registered trademark) 1000 is formed is attached. However, the region is not limited to this, and may be, for example, a region surrounded by a wiring pattern for a power source whose potential is a predetermined value VDD.

Further, in the second embodiment described above, the following restrictions may be added, which will be described with reference to FIG. FIG. 14 is a view of the mounting surface 63a of the main control board 63, and the wiring pattern 3000 described later, which is arranged on the back surface 63b side, and the first prohibited area 3005a and the second prohibited area 3005b on the back surface 63b side are shown. , Shown by the dotted line. Here, a region in which a wiring pattern that is surrounded by the same wiring pattern (for example, the same wiring pattern formed by solid wiring) does not exist is appropriately described as a “first non-wiring region”. Further, a region in which a wiring pattern does not exist but at least a part of the periphery is not surrounded by the same wiring pattern (for example, the same wiring pattern formed by solid wiring) is appropriately described as a "second non-wiring region". To do.

On the back surface 63b of the mounting surface 63a where the non-wiring region 2015 exists, a line overlaps with the non-wiring region 2015 when the back surface 63b is viewed from the vertical direction and the center line CL1 of the back surface 63b in the longitudinal direction of the back surface 63b. Area of symmetry (hereinafter referred to as "first prohibited area") Area of line symmetry with respect to the center line CL2 of the back surface 63b in the lateral direction of 3005a and the back surface 63b (hereinafter, "second prohibited area") 3005b is not defined as the first non-wiring region. That is, the first prohibited area 3005a and the second prohibited area 3005b are areas for prohibiting the first non-wiring area. In the example of FIG. 14, the wiring pattern 3000 formed by the solid wiring exists in the first prohibited area 3005a and the second prohibited area 3005b, and is not the first non-wiring area. The first prohibited area 3005a and the second prohibited area 3005b may be the second non-wiring area.

By doing so, even before mounting the components on the main control board 63, the mounting surface 63a and the back surface 63b of the main control board 63 can be easily distinguished by using the non-wiring region 2015. be able to.

Further, it may be prohibited to form the first non-wiring region on the back surface 63b.
