Description

  The present invention relates to a gaming machine including a board that requires security measures.

  Conventionally, in gaming machines such as pachinko machines and slot machines, a board (main control board or sub-control board) on which various components such as CPU, RAM, and ROM for controlling the operation of the gaming machine are mounted is made of synthetic resin. Is housed inside the substrate case.

  However, there is a possibility that a fraudulent act in which a prize ball or a medal is paid out with a probability higher than a predetermined probability by prying out the board case and replacing the board with an unauthorized one. In order to counter such fraud, for example, in the gaming machine described in Patent Document 1, the same and unique identification that identifies whether each of the cover member and the base member forming the board case is a regular board case or not The notation is provided individually.

JP 2009-165565 A (see paragraphs 0047, 0053, 0074, claim 1 etc.)

  However, even if an identification notation is provided on a regular board case as in Patent Document 1, there is a risk that employees in the hall may not be aware of the fraudulent act of storing a non-regular board in a regular board case. It seems to be lacking in effectiveness as a countermeasure.

  The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to effectively suppress an illegal act of attaching an unauthorized board to a gaming machine.

In order to achieve the above object, a gaming machine according to the present invention is a gaming machine including a board, which is a single solid wiring pattern arranged on one surface of the board, and the potential is a predetermined value. A first wiring pattern, a second wiring pattern disposed on another surface opposite to the one surface of the substrate and having a predetermined potential, the first wiring pattern, and the second wiring pattern; A plurality of through-holes that connect the first wiring pattern, specific information formed by silk printing or engraving on the first wiring pattern, an identification symbol that enables reading of the identification information of the substrate by using a reader, and a surface The identification symbol is formed, and a seal with an adhesive applied to the back surface thereof, and the plurality of through holes include a through hole on which a component mounted on the one surface side is not placed, The seal is in front Attached to a predetermined attaching area of the one surface side, the attaching area all is on said single solid wiring pattern, said plurality of through-holes and the specific information is arranged so as to avoid the sticking area It is characterized by being.

  According to this configuration, even when a regular board is replaced with a non-regular board, a seal with an identification symbol is affixed to one surface of the board, so that it is easily grasped that the board has been replaced. It is possible to effectively prevent an illegal act of attaching an unauthorized board to a gaming machine. In addition, since the identification symbol itself cannot be easily read by human beings such as alphanumeric characters, even if the fraudster sees the identification symbol, it cannot be easily duplicated. Actions can be effectively prevented.

  In addition, when the specific information is formed by silk printing, the specific information is formed so as to rise from the formation surface. When the specific information is formed by engraving, the specific information is displayed on the formation surface. It will be formed so as to be recessed. In addition, the end of the through hole may be uneven with respect to the formation surface. Further, the first wiring pattern formed on the surface of the substrate forms a step with respect to the surface of the substrate at the edge portion of the first wiring pattern.

  For this reason, if the through hole and the specific information are not arranged so as to avoid the pasting area, or if a part of the pasting area is on the first wiring pattern which is a single solid wiring pattern, the other part is If it is not on the first wiring pattern, a seal is affixed on the through hole or specific information, or a part of the seal is affixed so as to protrude from the first wiring pattern. May become uneven. When an identification symbol formed on the surface of such an uneven seal is imaged by a reader, the captured identification symbol is distorted, which may lead to erroneous recognition of the identification symbol. There is sex. Also, if the sticker is affixed on a through-hole or specific information, or if a part of the sticker sticks out of the first wiring pattern and is attached to a surface with irregularities, the seal will change over time. May be easily peeled off or easily damaged. If the seal is peeled off or damaged, there is a risk of misconception that there has been an illegal act. In such a case, there is a problem that the gaming machine cannot be operated.

  On the other hand, according to the above configuration, the entire sticking area of the seal is on the first wiring pattern which is a single solid wiring pattern, and the through holes and specific information are arranged so as to avoid the sticking area. Therefore, the seal is affixed to the affixing region on the first wiring pattern so that the whole exists on the first wiring pattern which is a single solid wiring pattern, avoiding through holes and specific information. Become. As a result, the surface of the seal becomes substantially flat, and when the identification symbol formed on the surface of such a substantially planar seal is imaged with a reader, the captured identification symbol is hardly distorted. Thus, erroneous recognition of the identification symbol can be prevented. In addition, the seal avoids through holes and specific information, and a part of the seal does not protrude from the first wiring pattern which is a single solid wiring pattern, so that the whole is present on the first wiring pattern. Therefore, it is possible to prevent the seal from being easily peeled or damaged due to secular change due to unevenness due to through holes, specific information, or steps at the edge of the first wiring pattern. Problems can be effectively suppressed.

  Further, in order to avoid the surface of the seal 131 from becoming uneven due to through holes, specific information, and steps of various wiring patterns, the entire pasting region 132 of the seal 131 is a single solid wiring pattern. When it is made to exist on one wiring pattern (hereinafter referred to as “first pasting area forming area pattern” as appropriate), a portion of the surface of the substrate having no wiring pattern (hereinafter referred to as “non-wiring pattern”). (Referred to as “second pasting area forming area pattern” where appropriate). At this time, for example, consider a case where a reader using light is used for reading the identification symbol. Since glass and flexible substrates that are generally used as substrates may transmit light, even if an attempt is made to read an identification symbol formed on the surface of a seal affixed entirely on a non-wiring pattern portion , May not be read (in the case of the second pasting area forming area pattern). On the other hand, since the first wiring pattern does not transmit light by the metal wiring layer, the light passes through the identification symbol formed on the surface of the seal 131 that is affixed entirely on the first wiring pattern. It is possible to read without being unable to be read due to the occurrence of the case (in the case of the first pasting area forming area pattern). From this point, it can be said that the first pasting region forming region pattern is superior to the second pasting region forming region pattern.

  The through hole may be arranged so as to avoid a predetermined first adjacent area adjacent to the pasting area.

  By the way, if there is a through hole in or near the identification symbol and the identification symbol is captured by a reader, the through hole appears in the image captured by the reader, and this reflected through hole is distinguished from the identification symbol. It is not possible to recognize it as a part of the identification symbol, which may lead to erroneous recognition of the identification symbol. On the other hand, according to the above configuration, the through hole is arranged so as to avoid the sticking area of the seal on which the identification symbol is formed and the predetermined first adjacent area adjacent to the sticking area of the identification symbol. Thus, it is possible to prevent erroneous recognition of the identification symbol caused by the reader reading the through hole as a part of the identification symbol.

In addition, in the arrangement area of the identification symbol and the predetermined second adjacent area adjacent to the arrangement area, a prohibited area in which a specific part whose height from the one surface may be a predetermined value or more is not installed. In addition, the center of the arrangement region may not coincide with the center of the predetermined second adjacent region .

  According to this configuration, when the identification symbol is read by the reader, it is possible to prevent the identification symbol from being greatly blurred due to focusing on the component, and the identification symbol from being read correctly.

Of the plurality of components arranged on the one surface, a component having the highest height from the one surface is defined as an identification symbol arrangement region and a predetermined second adjacent to the arrangement region. It may not be installed in an adjacent area, and the center of the arrangement area may not coincide with the center of the predetermined second adjacent area .

  According to this configuration, when the identification symbol is read by the reader, it is possible to prevent the identification symbol from being greatly blurred due to focusing on the component, and the identification symbol from being read correctly.

  Further, each of the main control board 63 and the sub control board 73 is affixed with a seal on which an identification symbol is formed so that the identification information of the board can be read by using a reader. This will be described in detail later with reference to FIGS.

  The RAM 65 of the main control board 63 temporarily stores data relating to the game such as the game state of the slot machine 1, and various storage areas for storing various data are formed.

  The ROM 67 of the main control board 63 stores a game machine program (a program for the slot machine 1) including preset data.

  Further, the main CPU 61 of the main control board 63 has an interrupt function such as a timer interrupt, and executes a game machine program stored in the ROM 67 to perform processing related to the progress of the game. In addition, the main CPU 61 sub-controls various game information such as information related to the result lottery results and information related to operation of operating instruments operated by the players such as the stop switches 21L, 21M, and 21R and the start switch 19 in a command format. It transmits to the board | substrate 73 (sub CPU71).

  The memory 75 of the sub-control board 73 includes a RAM unit that temporarily stores various data and a ROM unit that stores various programs for effects. The sub CPU 71 of the sub control board 73 has an interrupt function such as a timer interrupt, and the sub CPU 71 is stored in the memory 75 based on various game information regarding the slot machine 1 transmitted from the main CPU 61. The content of the production related to the game for the player is determined by executing the program. In addition, the sub CPU 71 of the sub control board 73 controls the effect devices such as the liquid crystal display 27 and the speakers 31L and 31R via the I / O port of the sub control board 73 based on the determined contents of the effect. I do.

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

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

  The main CPU 61 selects 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 more roles as a constituent role), winning / non-winning of the winning combination, etc. Control the game of the slot machine 1 to the state.

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

  Further, the main CPU 61 selects one combination lottery table from a plurality of combination lottery tables based on the type of gaming state controlled and the set setting values (setting 1 to setting 6). In the combination lottery table, for each of a plurality of predetermined winning combination groups, a winning combination group and a range of lottery values in which the winning combination group is won in 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 role lottery within a predetermined range, and at the timing when the start switch 19 is operated using the generated random number as the lottery value. Extract. Then, the main CPU 61 determines which winning combination group has been won using the selected winning lottery value table and the extracted lottery value.

  When the start switch 19 is operated by the player, the main CPU 61 starts the rotation of the reels 13L, 13M, and 13R, detects the left / middle / right position sensors 55L, 55M, and 55R, Based on the number of pulses supplied to the reel motors 14L, 14M, 14R for driving the middle / right reels 13L, 13M, 13R, the rotational positions of the left / middle / right reels 13L, 13M, 13R are detected. When all the reels 13L, 13M, and 13R are rotated at a constant speed, the main CPU 61 is in a state of accepting the operations of the stop switches 21L, 21M, and 21R as effective operations. When the player operates the stop switches 21L, 21M, and 21R in this state, the main CPU 61 detects the detected rotation positions of the left, middle, and right reels 13L, 13M, and 13R and the stop switches of the player. Each reel within a preset number of sliding frames (retractable range: normal, maximum 4 frames) based on the operation mode (for example, pressing order and operation timing) of 21L, 21M, and 21R and the winning lottery result Stop control is performed so that 13L, 13M, and 13R stop.

  After the rotation of all the reels 13L, 13M, and 13R is stopped, the main CPU 61 determines that the symbol combinations on the winning lines of the reels 13L, 13M, and 13R correspond to the symbols that make up the winning combination group won by the symbol 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 is won, and if not, it is determined to be lost. When the main CPU 61 determines that a winning combination of the winning combination group won by the winning lottery has been won, and if it is a winning combination with a medal payout, the main CPU 61 operates the hopper unit 43 to win the winning combination. The medals are paid out in the corresponding number of payouts. However, when the number of stored credit medals 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.

  In addition, the main CPU 61 determines whether the set value, gaming state, information on the result lottery result, information on the symbol determination result, rotation / stop state of each reel 13L, 13M, 13R, medal payout state, opening or closing of the front door 5 Various information such as data indicating the status of the slot machine 1 such as the status, the error status of the slot machine 1 and information relating to the operation of the operating devices operated by the player such as the stop switches 21L, 21M, 21R, the start switch 19, etc. A command to be transmitted 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 effects according to the operation and state of the main control board 63. 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 performs display control for displaying an image such as a moving image on the liquid crystal display 27 according to the determined content of the effect, or a speaker. The output control of the sound from 31L and 31R is performed, or the light sources of the upper lamp unit 33 and the lower lamp units 37L and 37R are controlled to blink simultaneously or individually.

(Arrangement position etc. of the seal on which the identification symbol is formed)
Subsequently, an arrangement position of the seal on which the identification symbols are formed on the main control board 63 and the sub control board 73 will be described with reference to FIGS. However, since the main control board 63 and the sub control board 73 follow the same idea about the arrangement position of the seal on which the identification symbol is formed, the main control board 63 and the sub control board 73 are described as the board 100. explain. In addition, when the slot machine 1 includes a board other than the main control board 63 and the sub control board 73 and a sticker having an identification symbol formed thereon is pasted, an arrangement position or the like of the seal having the identification mark is set. The same idea as the idea regarding the arrangement position of the seal on which the identification symbols for the main control board 63 and the sub control board 73 are formed can be followed.

A hole 106 is formed. Further, a through hole 110 is formed in the substrate 100 to connect the power wiring pattern 109 disposed on the front surface 100a and the power wiring pattern disposed on the back surface 100b (see FIG. 4). Further, a through hole 107 is formed in the substrate 100 to connect the signal wiring pattern 102 disposed on the front surface 100a and the signal wiring pattern disposed on the back surface 100b (see FIG. 4).

  Further, a predetermined area (hereinafter referred to as “applied area”) 132 to which the seal 131 is applied is predetermined on the surface 100a side of the substrate 100, and the entire applied area 132 is a single solid wiring pattern. On the wiring pattern 101.

  A seal 131 is disposed in the pasting area 132. In this embodiment, the seal 131 and the pasting area 132 are assumed to have the same size and the same shape, and the seal 131 is pasted so that the entire seal 131 fits in the pasting area 132. In this embodiment, it is assumed that the seal 131 and the pasting area 132 have the same size and the same shape. However, the present invention is not limited to this, and the pasting area 132 can be accommodated in the pasting area 132 as a whole. In this case, the seal 131 may be attached so that the seal 131 is attached so that the entire seal 131 is within the attachment region 132.

  A QR code (registered trademark) 120 is formed on the surface of the seal 131 so that the identification information of the substrate 100 can be read by using a reader. Adhesive is applied. The seal 131 is affixed to the affixing region 132 on the wiring pattern 101 by the adhesive applied to the back surface of the seal 131. The QR code (registered trademark) 120 corresponds to the “identification symbol” of the present invention.

  The QR code (registered trademark) 120 is captured by a camera or the like provided in the reader, and the captured image is analyzed by a computer or the like provided in the reader, so that information (identification information of the substrate 100 in this embodiment) is obtained. It can be read. Note that reading of the QR code (registered trademark) 120 by a reader is a known technique, and thus details thereof are omitted.

  The arrangement area 121 of the QR code (registered trademark) 120 has a rectangular shape surrounded by a dotted line in FIG. 4, and a printed portion (black portion of the portion surrounded by the dotted line in FIG. 4) and a printed portion (indicated by the dotted line in FIG. 4). White portion of the surrounding portion). Here, the three corners of the rectangle forming the arrangement area 121 correspond to the outermost corners of each finder pattern (cutout symbol, position detection pattern) of the QR code (registered trademark) 120, respectively.

  As described above, all the pasting regions 132 are on the wiring pattern 101 which is a single solid wiring pattern. Therefore, the entire sticker 131 stuck in the sticking region 132 exists on the wiring pattern 101. In addition, the entire QR code (registered trademark) 120 formed on the seal 131 and the entire arrangement region 121 are naturally present on the wiring pattern 101.

  The through hole 106 described above is arranged so as to avoid the pasting area 132 so that even a part of the through hole 106 is not included in the pasting area 132. That is, even a part of the through hole 106 does not exist in the pasting area 132. Further, the part information 150 is arranged so as to avoid the pasting area 132 so that a part of the part information 150 is not included in the pasting area 132. That is, even part of the component information 150 does not exist in the pasting area 132. Therefore, the through hole 106 and the part information 150 do not exist under the seal 131 attached to the attachment region 132. Since the entire pasting region 132 to which the seal 131 is pasted is on the wiring pattern 101, it is natural that the through holes 107 and 110 other than the through hole 106 exist under the seal 131 pasted to the pasting region 132. Absent.

  An area 145 including an arrangement area 121 of the QR code (registered trademark) 120 and a predetermined area adjacent to the arrangement area 121 (hereinafter referred to as “arrangement adjacent area”) 140 is formed on the surface 100a (single solid wiring). Specific components (for example, one-way insertion mounting type or TO type used in some capacitors, filters, and ICs) whose height from the wiring pattern 101) that is the pattern may be a predetermined value H or more The area where no package or connector is placed. This area 145 is referred to as an arrangement prohibition area 145. In addition, it is prohibited to dispose a specific part whose height is likely to be equal to or higher than the predetermined value H so as to be included in the disposition prohibition region 145. The arrangement adjacent area 140 corresponds to the “second adjacent area” of the present invention, and the arrangement prohibition area 145 corresponds to the “prohibited area” of the present invention.

  In this embodiment, the arrangement adjacent area 140 has a frame shape with a square outer shape centered on the center of the arrangement area 121, and each side of the arrangement area 121 and each edge of the outline of the arrangement adjacent area 140 Is set to a predetermined value. When the arrangement adjacent region 140 is set first, for example, a test is performed by preparing a plurality of specific parts having different heights and performing a false recognition of the QR code (registered trademark) 120. The predetermined value H actually used may be determined according to the result. If the predetermined value H is set first, for example, a test is performed by preparing a plurality of arrangement adjacent regions 140 having different sizes and shapes and performing erroneous recognition of the QR code (registered trademark) 120. Depending on the result, the size and shape of the arrangement adjacent region 140 that is actually used may be determined.

  The placement prohibition area 145 is a part of a specific package (for example, a part of a one-way insertion mounting type or a TO type package), or a fixed part, instead of being an area for prohibiting the placement of parts having a predetermined value H or more. It is also possible to use a region where it is prohibited to place parts (large capacitors, large filters, connectors, etc.).

  The center of the arrangement adjacent area 140 and the center of the arrangement area 121 are not limited to the same, and for example, the pasting area 132 to which the seal 131 on which the QR code (registered trademark) 120 is formed is attached to the substrate 100. In the case where the center of the arrangement adjacent area 140 and the center of the arrangement area 121 do not coincide with each other, the arrangement adjacent area 140 may be set.

  As described above, the components 103A, 103B, and 103C are mounted on the surface 100a of the substrate 100. As shown in FIGS. 4 and 5, the component 103 </ b> A is arranged in the arrangement prohibited area 145, but the height of the component 103 </ b> A is less than a predetermined value H as shown in FIG. 5. Further, as shown in FIG. 5, the height of the back of the component 103B is equal to or greater than the predetermined value H, but as shown in FIGS. 4 and 5, the entire component 103B is placed outside the placement prohibition area 145. Yes. Further, the part 103 </ b> C is disposed so that the entire part 103 </ b> C is outside the placement prohibition area 145 as shown in FIGS. 4 and 5, and the height of the part is less than a predetermined value H. Therefore, a specific component whose height may be equal to or higher than the predetermined value H is not arranged in the arrangement prohibition area 145. That is, FIG. 5 shows a component arrangement that satisfies the condition that a specific component whose height may be equal to or higher than the predetermined value H is not installed in the arrangement prohibition area 145.

  In the case of FIG. 6A, only the parts 103A, 103B, and 103C are arranged on the surface 100a of the substrate 100, and the part 103A is the tallest part among the parts 103A, 103B, and 103C. Suppose that the height of the component is less than a predetermined value H. As shown in FIG. 6A, the part 103A is arranged in the arrangement prohibition area 145. The part 103A is the tallest part among the parts 103A, 103B, and 103C, but its height is It is less than the predetermined value H. Also, as shown in FIG. 6A, the parts 103B and 103C are arranged so that the whole is outside the arrangement prohibited area 145, and the height of the spine is less than a predetermined value H. Therefore, a specific component whose height may be equal to or higher than the predetermined value H is not arranged in the arrangement prohibition area 145. That is, FIG. 6A shows a component arrangement that satisfies the condition that a specific component whose height may be equal to or higher than the predetermined value H is not installed in the arrangement prohibition area 145.

  However, FIG. 6A in which the tallest component 103A is arranged in the arrangement prohibition area 145 is shown in FIG. 8 in which the tallest part is not installed in the arrangement prohibition area 145. The component arrangement does not satisfy the conditions in the third embodiment to be described later.

  In the case of FIG. 6B, only the components 103B and 103C are arranged on the surface 100a of the substrate 100. As shown in FIG. 6B, the parts 103 </ b> B and 103 </ b> C are arranged so that the whole is outside the arrangement prohibited area 145. Therefore, a specific component whose height may be equal to or higher than the predetermined value H is not arranged in the arrangement prohibition area 145. That is, FIG. 6B shows a component arrangement that satisfies the condition that a specific component whose height may be equal to or higher than the predetermined value H is not installed in the arrangement prohibition area 145.

  As shown in FIG. 6B, even if the height of the component 103B closest to the QR code (registered trademark) 120 is equal to or greater than a predetermined value H, the component 103B appears to be outside the placement prohibited area 145. If the components are arranged, the component arrangement satisfies the above conditions.

  In a state where the substrate 100 is attached to the predetermined inner wall surface of the housing 3, the back surface 100 b faces the predetermined inner wall surface. In the case of the main control board 63 attached as shown in FIG. 2, the main control board 63 is located so that the front surface 100 a is located on the front side of the housing 3 and the back surface 100 b is located on the inner wall surface on the rear side of the housing 3. The control board 63 is attached to the rear inner wall surface in the housing 3 so that the back surface 100b faces the rear inner wall surface. Further, in the case where the substrate 100 is the sub control substrate 73 attached as shown in FIG. 2, the front surface 100 a is positioned on the right inner wall surface side of the housing 3, and the back surface 100 b is positioned on the left inner wall surface side of the housing 3. The sub-control board 73 is attached to the left inner wall surface in the housing 3, and the back surface 100b faces the left inner wall surface. Note that “left” and “right” mean “left” and “right” when the slot machine 1 is viewed from the front side of the slot machine 1 in FIG.

  Therefore, according to the first embodiment described above, even if the regular substrate 100 is replaced with a non-regular substrate, the QR code (registered trademark) 120 is applied to the surface 100a of the substrate 100 (main control substrate 63, sub control substrate 73). Since the sticker 131 is formed, it is possible to easily grasp that the seal 131 has been replaced, and it is possible to effectively prevent an illegal act of attaching an unauthorized board to the slot machine 1. In addition, since the QR code (registered trademark) 120 itself cannot be easily read by a person such as alphanumeric characters, even if an unauthorized person views the QR code (registered trademark) 120, it is easily copied. In this respect, fraudulent acts can be effectively prevented.

  Further, when the component information 150 is formed by silk printing, the component information 150 is formed so as to rise from the formation surface (see FIGS. 5, 6A, and 6B). Further, the end of the through hole 106 may be uneven with respect to the formation surface. Further, the wiring pattern 101 which is a single solid wiring pattern formed on the surface 100 a of the substrate 100 has a step formed on the edge of the wiring pattern 101 with respect to the surface of the substrate.

  For this reason, if the through hole 106 and the component information 150 are not arranged so as to avoid the pasting area 132, or a part of the pasting area 132 is on the wiring pattern 101 that is a single solid wiring pattern, If the part is not on the wiring pattern 101, the sticker 131 is stuck on the through hole 106 or the component information 150, or a part of the sticker 131 is stuck on the wiring pattern 101. The surface of the seal 131 may become uneven. When the QR code (registered trademark) 120 formed on the surface of the uneven seal 131 is imaged with a reader, the captured QR code (registered trademark) 120 is distorted. This may lead to erroneous recognition of the QR code (registered trademark) 120. Further, when the seal 131 is affixed on the through-hole 106 or the component information 150, or when a part of the seal 131 is affixed so as to protrude from the wiring pattern 101, the seal 131 is affixed to the surface with unevenness. 131 tends to be peeled off or easily damaged due to secular change. If the seal 131 is peeled off or damaged, it may be mistaken for fraud, and in such a case, the slot machine 1 cannot be operated.

  On the other hand, according to the first embodiment described above, the entire pasting area 132 of the seal 131 is on the wiring pattern 101 which is a single solid wiring pattern, and the through hole 106 and the component information 150 include the pasting area 132. Arranged to avoid. For this reason, the seal 131 is affixed to the affixing region 132 on the wiring pattern 101 so as to be present on the wiring pattern 101, which is a single solid wiring pattern, avoiding the through hole 106 and the component information 150. Will be. As a result, the surface of the seal 131 becomes substantially flat. When the QR code (registered trademark) 120 formed on the surface of the substantially flat seal 131 is imaged by a reader, the imaged QR code (registered) is registered. (Trademark) 120 is hardly distorted, and erroneous recognition of QR Code (registered trademark) 120 can be prevented. Further, the seal 131 avoids the through hole 106 and the component information 150 and is substantially flat so that the entire portion exists on the wiring pattern 101 without protruding from the wiring pattern 101 which is a single solid wiring pattern. Since it is affixed to the top, it is possible to prevent the seal 131 from being easily peeled or damaged due to secular change due to unevenness due to the through hole 106 or the component information 150 or a step at the edge of the wiring pattern 101. The above-mentioned problems can be effectively suppressed.

  In order to prevent the surface of the seal 131 from becoming uneven due to the through hole 106, the component information 150, and the steps of various wiring patterns, the entire pasting region 132 of the seal 131 is as in the first embodiment. When it is made to exist on a single solid wiring pattern such as the wiring pattern 101 (hereinafter, referred to as “first pasting area forming area pattern” as appropriate), wiring on the surface 100a of the substrate 100 is used. There is a case where it is made to exist on a portion having no pattern (hereinafter referred to as “non-wiring pattern portion”) (hereinafter referred to as “second pasting region forming region pattern” as appropriate). . At this time, for example, consider a case where a reader using light is used to read the QR code (registered trademark) 120. Since a glass substrate or flexible substrate generally used as the substrate 100 may transmit light, a QR code (registered trademark) formed on the surface of the seal 131 affixed entirely on the non-wiring pattern portion. ) 120 may not be read even if it is read (in the case of the second pasting area forming area pattern). On the other hand, since the wiring pattern such as the wiring pattern 101 does not transmit light through the metal wiring layer, the QR code formed on the surface of the seal 131 that is entirely attached on the wiring pattern such as the wiring pattern 101. (Registered trademark) 120 can be read without being unable to be read due to the transmission of light (in the case of the first pasting area forming area pattern). From this point, it can be said that the first pasting region forming region pattern is superior to the second pasting region forming region pattern.

  In the above-described embodiment, a specific part having a height of a predetermined value H or more is arranged in an area including the arrangement area 121 of the QR code (registered trademark) 120 and the arrangement adjacent area 140 adjacent to the arrangement area 121. This is a placement prohibition area 145 that prohibits this. In this way, when the QR code (registered trademark) 120 is read by the reader, the QR code (registered trademark) 120 is largely blurred due to the focus on the component, and the QR code (registered trademark) 120 is read correctly. Can be prevented from becoming impossible.

  For example, when the seal 131 is opaque, for example, when the seal 131 is pasted so as to straddle a plurality of arrangement patterns (for example, the arrangement pattern 101 and the arrangement pattern 102), the wiring pattern is provided under the seal 131. There is a problem that it is difficult to grasp whether or not there exists. On the other hand, in 1st Embodiment, it can suppress effectively that the above-mentioned malfunction arises by making all the sticking area | regions 132 of the sticker 131 on the wiring pattern 101 which is a single solid wiring pattern.

Second Embodiment
A slot machine as an example of a gaming machine according to the second embodiment of the present invention will be described with reference to FIG.

  In the first embodiment, the through hole 106 is arranged so as to avoid the pasting area 132, whereas in the second embodiment, the through hole 106 is a pasting area 132 and a predetermined area adjacent to the pasting area 132 (hereinafter referred to as the pasting area 132). , “Attached adjacent area”.) This is different in that it is arranged so as to avoid 160. Except for this point, the first embodiment and the second embodiment are the same. In the second embodiment, the same reference numerals are given to the components corresponding to those of the first embodiment, and the description of the first embodiment. Since this is applicable, the description thereof is omitted. Moreover, in 2nd Embodiment, although the effect similar to 1st Embodiment will be show | played by the structure corresponding to the structure of 1st Embodiment, since description of 1st Embodiment is applicable, the description is abbreviate | omitted. .

  The through hole 106 is disposed so as to avoid the pasting region 132 and a predetermined region (a pasting adjacent region) 160 adjacent to the pasting region 132. That is, the pasting region 132 and the pasting adjacent region 160 are regions (hereinafter referred to as “through-hole placement prohibiting region”) 165 that prohibits the placement of through holes. The through hole 106 is not arranged so that even a part thereof is included in the through hole arrangement prohibition region 165. The pasting adjacent area 160 corresponds to the “first adjacent area” of the present invention.

  In this embodiment, the pasting adjacent area 160 is determined such that the distance between each side of the pasting area 132 and each side of the outer shape of the pasting adjacent area 160 is a predetermined value that is equal to each other. For example, the size of the pasting adjacent area 160 is prepared by preparing a plurality of patterns in which the through holes 106 are provided in the vicinity of the pasting area 132 in advance and testing whether the QR code (registered trademark) 120 is erroneously recognized. Thus, the size of a predetermined adjacent area that is actually used may be determined according to the test result.

  Note that the pasting adjacent area 160 is not limited to the distance between each side of the pasting area 132 and each side of the outer shape of the pasting adjacent area 160. For example, the pasting adjacent area 160 is as follows. Also good. When the pasting region 132 to which the seal 131 on which the QR code (registered trademark) 120 is formed is located near the edge of the substrate 100, the side near the edge of the substrate 100 in the pasting region 132 and the pasting adjacent portion. The pasting adjacent region so that the distance between the side of the region 160 near the edge of the substrate 100 is smaller than the distance between each other side of the pasting region 132 and each other side of the pasting adjacent region 160. 160 may be set.

  If a part of the through hole arrangement prohibition area 165 protrudes from the wiring pattern 101 and is on the wiring pattern 102 or the wiring pattern 109, for example, the through holes 107 and 110 avoid the through hole arrangement prohibition area 165. You may make it arrange | position to.

  Therefore, according to the second embodiment described above, the through-hole arrangement prohibition formed by the pasting area 132 to which the seal 131 formed with the QR code (registered trademark) 120 is pasted and the pasting adjacent area 160 adjacent to the pasting area 132 is prohibited. The through hole 106 does not exist in the region 165. For this reason, the reader mistakes the through hole 106 for the printed portion of the QR code (registered trademark) 120 (the black portion of the portion surrounded by the dotted line in FIG. 4A) and a part of the QR code (registered trademark) 120. As a result, it is possible to prevent erroneous recognition of the QR code (registered trademark) 120 resulting from reading as. For example, a finder pattern or alignment pattern of QR Code (registered trademark) 120 has a shape similar to the shape of the through hole 106 in a plan view when the surface 100a is viewed from a direction perpendicular to the surface 100a of the substrate 100. It is conceivable that the hole 106 is mistaken for a finder pattern or an alignment pattern of the QR code (registered trademark) 120. However, in the second embodiment, since the through hole 106 does not exist in the through hole arrangement prohibition region 165, the through hole 106 is erroneously read in the finder pattern or alignment pattern of the QR code (registered trademark) 120. Can be prevented.

<Third Embodiment>
A slot machine which is an example of a gaming machine according to the third embodiment of the present invention will be described with reference to FIG.

  In the first embodiment, the parts that are prohibited from being placed in the placement prohibited area 145 are parts whose height is a predetermined value H or more, whereas in the third embodiment, the parts are placed in the placement prohibited area 145. This is different in that it is the tallest component among the plurality of components mounted on the surface 100a forbidden. Except for this point, the first embodiment and the third embodiment are the same. In the third embodiment, the same reference numerals are given to the components corresponding to the components of the first embodiment, and the description of the first embodiment. Since this is applicable, the description thereof is omitted. Moreover, in 3rd Embodiment, although the effect similar to 1st Embodiment will be show | played by the structure corresponding to the structure of 1st Embodiment, since description of 1st Embodiment is applicable, the description is abbreviate | omitted. .

  In the third embodiment, it is irrelevant whether or not the height of a part prohibited from being placed in the placement prohibited area 145 is greater than or equal to a predetermined value H, but can be compared with the first embodiment. Therefore, in FIGS. 8A to 8C, a solid line is attached to a position whose height is a predetermined value H from the surface 100a.

  In the third embodiment, only three components 203A, 203B, and 203C are mounted on the surface 100a of the substrate 100 in the case of FIGS. 8A and 8B, and FIG. In this case, it is assumed that only two components 203A and 203B are mounted, but the number of components to be mounted is not limited to this.

  Further, for example, a tallest component among components supposed to be arranged on the surface 100a of the substrate 100 and a plurality of arrangement adjacent regions 140 having different sizes and shapes are prepared, and a QR code (registered trademark) is prepared. ) It is also possible to test whether or not 120 is erroneously recognized, and to determine the size and shape of the arrangement adjacent region 140 that is actually used according to the test result.

  In the case of FIG. 8A, among the components 203A, 203B and 203C, the component 203B is the tallest component from the surface 100a (the wiring pattern 101 which is a single solid wiring pattern). To do. As shown in FIG. 8A, the component 203A is arranged in the arrangement prohibition area 145, but the component 203A is not the tallest component among the components 203A, 203B, and 203C. Further, as shown in FIG. 8A, the tallest component 203B among the components 203A, 203B, and 203C is arranged so that the whole is outside the arrangement prohibition area 145, and the component 203C is entirely arranged. It arrange | positions so that it may become out of the arrangement | positioning prohibition area | region 145. Therefore, the tallest component 203B is not arranged in the arrangement prohibition area 145. That is, FIG. 8A shows a component placement that satisfies the condition that the tallest component 203B is not placed in the placement prohibited area 145.

  In the case of FIG. 8B, the component 203B among the components 203A, 203B, and 203C is the tallest component from the surface 100a (the wiring pattern 101 that is a single solid wiring pattern). To do. As shown in FIG. 8B, the component 203A is arranged in the arrangement prohibition area 145, and the component 203A has a height of not less than a predetermined value H, but the most of the components 203A, 203B, and 203C. It is not a tall part. Further, as shown in FIG. 8B, the tallest component 203B among the components 203A, 203B, and 203C is arranged so that the whole is outside the arrangement prohibition area 145, and the component 203C is entirely arranged. It arrange | positions so that it may become out of the arrangement | positioning prohibition area | region 145. Therefore, the tallest component 203B is not arranged in the arrangement prohibition area 145. That is, FIG. 8B shows a component placement that satisfies the condition that the tallest component 203B is not placed in the placement prohibited area 145.

  However, in FIG. 8B in which the component 203A whose height is equal to or higher than the predetermined value H is arranged in the arrangement prohibition area 145, a component whose height is higher than the predetermined value H is not installed in the arrangement prohibition area 145. That is, the component arrangement does not satisfy the condition in the first embodiment.

  In the case of FIG. 8C, it is assumed that the component 203B is the tallest component from the surface 100a (the wiring pattern 101 which is a single solid wiring pattern) among the components 203B and 203C. As shown in FIG. 8C, the tallest component 203B among the components 203B and 203C is arranged so that the whole is outside the arrangement prohibition area 145, and the whole of the part 203C is the arrangement prohibition area 145. It is arranged to be outside. Therefore, the tallest component 203B is not arranged in the arrangement prohibition area 145. That is, FIG. 8C shows a component placement that satisfies the condition that the tallest component 203B is not placed in the placement prohibited area 145.

  As shown in FIG. 8C, even if the component 203B closest to the QR code (registered trademark) 120 is the tallest component, the component 203B is arranged so as to exist outside the arrangement prohibition area 145. If so, it is a component arrangement that satisfies the above conditions.

  As described above, in the third embodiment, a plurality of components arranged on the surface 100a of the substrate 100 (the components 203A, 203B, and 203C in FIGS. 8A and 8B, and the component 203B in FIG. 8C). 203C), the tallest part is not installed in the arrangement area 121 of the QR code (registered trademark) 120 and the predetermined arrangement adjacent area 140 adjacent to the arrangement area 121. .

  Therefore, according to the third embodiment described above, the tallest component 203B is not installed in the arrangement area 121 of the QR code (registered trademark) 120 and the arrangement adjacent area 140 adjacent to the arrangement area 121. In this way, when the QR code (registered trademark) 120 is read by the reader, the QR code (registered trademark) 120 is largely blurred due to the focus on the component, and the QR code (registered trademark) 120 is read correctly. Can be prevented from becoming impossible.

  Note that 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 each of the embodiments described above, the component information 150 is formed by silk printing. However, the present invention is not limited to this. For example, the component information 150 may be formed by marking with a laser or the like. When the component information 150 is formed by engraving, the component information 150 is formed so as to be recessed from the formation surface, unlike when formed by silk printing. Further, the end of the through hole 106 may be uneven with respect to the formation surface. Further, the wiring pattern 101 which is a single solid wiring pattern formed on the surface 100 a of the substrate 100 has a step formed on the edge of the wiring pattern 101 with respect to the surface of the substrate.

  For this reason, if the through hole 106 and the component information 150 are not arranged so as to avoid the pasting area 132, or a part of the pasting area 132 is on the wiring pattern 101 that is a single solid wiring pattern, If the part is not on the wiring pattern 101, the sticker 131 is stuck on the through hole 106 or the component information 150, or a part of the sticker 131 is stuck on the wiring pattern 101. The surface of the seal 131 may become uneven. When the QR code (registered trademark) 120 formed on the surface of the uneven seal 131 is imaged with a reader, the captured QR code (registered trademark) 120 is distorted. This may lead to erroneous recognition of the QR code (registered trademark) 120. Further, when the seal 131 is affixed on the through-hole 106 or the component information 150, or when a part of the seal 131 is affixed so as to protrude from the wiring pattern 101, the seal 131 is affixed to the surface with unevenness. 131 tends to be peeled off or easily damaged due to secular change. If the seal 131 is peeled off or damaged, it may be mistaken for fraud, and in such a case, the slot machine 1 cannot be operated.

  On the other hand, according to the above-described modification, the entire pasting area 132 of the seal 131 is on the wiring pattern 101 which is a single solid wiring pattern, and the through hole 106 and the component information 150 avoid the pasting area 132. Is arranged. For this reason, the seal 131 is affixed to the affixing region 132 on the wiring pattern 101 so as to be present on the wiring pattern 101, which is a single solid wiring pattern, avoiding the through hole 106 and the component information 150. Will be. As a result, the surface of the seal 131 becomes substantially flat. When the QR code (registered trademark) 120 formed on the surface of the substantially flat seal 131 is imaged by a reader, the imaged QR code (registered) is registered. (Trademark) 120 is hardly distorted, and erroneous recognition of QR Code (registered trademark) 120 can be prevented. Further, the seal 131 avoids the through hole 106 and the component information 150 and is substantially flat so that the entire portion exists on the wiring pattern 101 without protruding from the wiring pattern 101 which is a single solid wiring pattern. Since it is affixed to the top, it is possible to prevent the seal 131 from being easily peeled or damaged due to secular change due to unevenness due to the through hole 106 or the component information 150 or a step at the edge of the wiring pattern 101. The above-mentioned problems can be effectively suppressed.

  In each of the above-described embodiments, the identification symbol is the QR code (registered trademark) 120 which is a two-dimensional code. However, the present invention is not limited to this, and a two-dimensional code other than the QR code (registered trademark) 120 is used. It may be a code. Further, the identification symbol is not such that identification information directly represented by the identification symbol is read by a person, and the identification information represented by the identification symbol can be read by using a reader, for example, 1 A dimensional code, a two-dimensional code, or the like may be used.

  Further, in each of the above-described embodiments, the entire pasting region 132 of the seal 131 is on the ground wiring pattern 101 which is a single solid wiring pattern. However, the present invention is not limited to this. When the power supply wiring pattern 109 having the value VDD is a single solid wiring pattern, all the pasting regions 132 of the seal 131 may be on the single solid wiring pattern 109.

However, the present invention is not limited to this, and may be as follows, for example. Of the plurality of components mounted on the surface 100a of the substrate 100, each component may be arranged so that the component closest to the QR code (registered trademark) 120 is not the tallest component. In this case, the component arrangement shown in FIGS. 6B and 8C is not allowed.

  In each of the above-described embodiments, the QR code (registered trademark) 120 is disposed on the surface 100a side where the components of the substrate 100 are disposed. However, the present invention is not limited to this, and the components of the substrate 100 are not limited thereto. You may make it arrange | position to the back surface 100b side which is not arrange | positioned. In this case, all the sticking areas of the sticker are on a single solid wiring pattern (for example, a single solid wiring pattern for ground whose potential is a predetermined value 0, a wiring pattern for power supply whose potential is a predetermined value VDD). Yes, the entire seal may be affixed within the affixing area, and the specific information formed by through holes and silk printing or engraving may be arranged to avoid the affixing area.
