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, and the board is a main control board on which main control means for controlling the progress of the game is mounted, or A sub-control board on which sub-control means for performing control related to a predetermined effect based on information transmitted from the main control means is mounted, and is arranged on one surface of the board, and a first wiring pattern having a predetermined potential And a through hole that is disposed on the other surface opposite to the one surface of the substrate and connects the second wiring pattern having the predetermined potential and the first wiring pattern and the second wiring pattern. And an identification symbol arranged on the one surface and capable of reading the identification information of the substrate by using a reader, and the arrangement region of the identification symbol is rectangular, and the identification symbol The arrangement region and a predetermined adjacent area adjacent to the placement area of the identification mark is characterized in that there are no said through hole.

  According to this configuration, even if a regular board is replaced with a non-regular board, the identification symbol is arranged on one surface of the board, so that the replacement can be easily grasped. It is possible to effectively prevent an illegal act of attaching a non-genuine board to the board. 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 a through hole exists 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 the 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, since the through hole does not exist in the arrangement area of the identification symbol and the predetermined adjacent area adjacent to the arrangement area of the identification symbol, the reader does not provide the through hole. It is possible to prevent erroneous recognition of the identification symbol due to reading as a part of the identification symbol.

  In addition, the first wiring pattern is a single solid wiring pattern, the entire area where the identification symbols are arranged is on the single solid wiring pattern, and each side of the area where the identification symbols are arranged is the single solid wiring pattern. It may not be in contact with the periphery of the solid wiring pattern.

  If an identification symbol is placed so as to straddle multiple wiring patterns, or if an identification symbol is placed around each wiring pattern so that each side of the identification symbol placement area is in contact with the wiring pattern, the wiring is placed under the identification symbol. There is a problem that it is difficult to grasp whether or not a pattern exists, and a problem that a variation in the resistance value of the wiring pattern becomes large. On the other hand, according to this configuration, all the arrangement area of the identification symbol is on a single solid wiring pattern, and each side of the arrangement area of the identification symbol is not in contact with the periphery of the single solid wiring pattern, It is possible to effectively suppress the occurrence of the above-described problems.

  In addition, the identification symbol is a two-dimensional code, and among the components mounted on the one surface, the component closest to the identification symbol is any one other than the component having the highest height from the one surface. It may be.

  According to this configuration, when the two-dimensional code is read by the reader, it is possible to prevent the two-dimensional code from being greatly blurred due to the focus on the component and being unable to read the two-dimensional code correctly. it can.

  The gaming machine includes a housing having a front surface opened and a front door that opens and closes an open portion of the housing, and the board is installed on a predetermined inner wall surface of the gaming machine housing. The one surface on which the identification symbol is arranged may face the predetermined inner wall surface of the housing.

  According to this configuration, even when the front door is open, it is possible to effectively prevent an unauthorized person from easily accessing or viewing the identification symbol arranged on one surface of the substrate. be able to.

  The identification symbol may be formed by marking using a laser marker.

  According to this configuration, the identification symbol can be easily formed on one surface of the substrate using existing technology, and the marking cannot be erased, so that the identification symbol can be effectively prevented from being counterfeited. it can.

  Further, the marking of the identification symbol may be formed at a predetermined depth that is difficult to visually recognize.

  According to this configuration, it is difficult for a fraudulent person to specify the arrangement position of the identification symbol, and thus it is possible to effectively prevent the fraudulent person from easily accessing or viewing the identification symbol. .

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 whether or not the winning combination group is 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.

(Identification symbol location, etc.)

  Also, a QR code (registered trademark) 108 that allows reading of identification information of the substrate 100 by using a reader on the back surface 100b of the substrate 100 has a predetermined depth that is difficult to visually recognize on the wiring pattern 104 using a laser marker. It is formed by imprinting (for example, 100 μm). However, for example, a QR code (registered trademark) 108 is previously engraved on the wiring pattern at a plurality of depths to test whether it is difficult to visually recognize, and a predetermined depth actually used is determined according to the test result. Like that. The QR code (registered trademark) 108 corresponds to the “identification symbol” of the present invention.

  The QR code (registered trademark) 108 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) 108 by a reader is a known technique, and the details are omitted.

  In a state where the substrate 100 is attached to a predetermined inner wall surface of the housing 3, the back surface 100 b on which the QR code (registered trademark) 108 is disposed 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 100a is located on the front side of the housing 3 and the back surface 100b 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.

  The arrangement area 121 of the QR code (registered trademark) 108 has a rectangular shape surrounded by a dotted line in FIG. 4A, and a marking portion (a black portion of a portion surrounded by a dotted line in FIG. 4A) and a portion to be marked. (The white portion of the portion surrounded by the dotted line in FIG. 4A). Here, the three corners of the rectangle forming the arrangement area 121 correspond to the outermost corners of the respective finder patterns (cutout symbols and position detection patterns) of the QR code (registered trademark) 108.

  All of the arrangement area 121 of the QR code (registered trademark) 108 is on the wiring pattern 104 which is a single solid wiring pattern, and the arrangement area 121 in a plan view of the back surface 100b viewed from the direction perpendicular to the back surface 100b of the substrate 100. These sides are not in contact with the periphery of the wiring pattern 104.

  The through hole 106 does not exist in the arrangement prohibition area 122 surrounded by the one-dot chain line in FIG. 4A including the arrangement area 121 of the QR code (registered trademark) 108 and a predetermined adjacent area adjacent to the arrangement area 121. However, for example, the size of a predetermined adjacent area adjacent to the arrangement area 121 is determined by preparing a plurality of patterns in which through-holes 106 are provided in the vicinity of the arrangement area 121 of the QR code (registered trademark) 108 in advance. A test of whether or not the trademark 108 is erroneously recognized is performed, and the size of a predetermined adjacent region to be actually used is determined according to the test result. For example, in a plan view of the back surface 100b viewed from a direction perpendicular to the back surface 100b of the substrate 100, the size of the width of the adjacent region is equal to the diameter of the through hole 106. When the number of through holes 106 that connect the wiring pattern 101 and the wiring pattern 104 is small, the wiring resistance increases and the potential of the wiring patterns 101 and 104 varies. It is preferable to consider so that the number does not decrease.

  Therefore, according to the above-described embodiment, the QR code (registered trademark) 108 is arranged on the back surface 100b of the substrate 100 (the main control substrate 63 and the sub control substrate 73) even if the regular substrate 100 is replaced with a non-regular substrate. Therefore, it is possible to easily grasp the replacement, and it is possible to effectively prevent an illegal act of attaching an unauthorized board to the slot machine 1. Also, since the QR code (registered trademark) 108 itself is not something that can be easily read by people such as alphanumeric characters, even if an unauthorized person sees the QR code (registered trademark) 108, it is easily copied. In this respect, fraudulent acts can be effectively prevented.

  In addition, since the through hole 106 does not exist in the arrangement prohibition area 122 including the arrangement area 121 of the QR code (registered trademark) 108 and a predetermined adjacent area adjacent to the arrangement area 121, the reader can make a through hole. QR code resulting from erroneously reading 106 as a part of the QR code (registered trademark) 108 and the stamped portion of the QR code (registered trademark) 108 (the black portion of the portion surrounded by the dotted line in FIG. 4A). Misrecognition of (registered trademark) 108 can be prevented. For example, a finder pattern or alignment pattern of QR code (registered trademark) 108 has a shape similar to the shape of the through hole 106 in a plan view when the back surface 100b is viewed from the direction perpendicular to the back surface 100b of the substrate 100. Although it is conceivable that the hole 106 is misidentified as a finder pattern, an alignment pattern, or the like of the QR code (registered trademark) 108, in the embodiment, the through hole 106 does not exist in the arrangement prohibition region 122. Can be prevented from being erroneously read into the finder pattern or alignment pattern of the QR code (registered trademark) 108.

  In addition, the QR code (registered trademark) 108 is arranged so as to straddle a plurality of arrangement patterns (for example, the arrangement pattern 104 and the arrangement pattern 105), or the arrangement region 121 of the QR code (registered trademark) 108 around the wiring pattern 104. When the identification symbol is arranged so that each side of the line is in contact with each other, it is difficult to grasp whether the wiring pattern exists under the QR code (registered trademark) 108, and the resistance value of the wiring pattern There are problems such as large fluctuations. On the other hand, in the embodiment, the entire arrangement area 121 of the QR code (registered trademark) 108 is placed on the wiring pattern 104 which is a single solid wiring pattern, and each side of the arrangement area 121 is a wiring pattern having a single solid wiring pattern. By not contacting the periphery of 104, it is possible to effectively suppress the occurrence of the above-mentioned problems.

  Further, in a state where the substrate 100 is attached to a predetermined wall in the housing 3, the back surface 100b on which the QR code (registered trademark) 108 is arranged faces the predetermined wall. Even in the open state, it is possible to effectively prevent an unauthorized person from easily accessing or viewing the QR code (registered trademark) 108 disposed on the back surface 100b of the substrate 100. .

  In addition, by using a laser marker for marking the wiring pattern 104 of the QR code (registered trademark) 108, it is possible to easily mark the wiring pattern 104 of the QR code (registered trademark) 108 using existing technology. In addition, since the stamp cannot be erased, it is possible to effectively prevent forgery of the identification symbol.

  In addition, since the engraving on the wiring pattern 104 of the QR code (registered trademark) 108 is formed at a predetermined depth that is difficult to visually recognize, it is difficult for an unauthorized person to specify the arrangement position of the QR code (registered trademark) 108. Thereby, it is possible to effectively prevent an unauthorized person from easily accessing or viewing the QR code (registered trademark) 108.

  Note that when the QR code (registered trademark) 108 is formed on the wiring pattern 104 by engraving, the resistance value of the wiring pattern 104 changes due to the engraving, so that the change in the resistance value of the wiring pattern is suppressed. In addition, it is conceivable to form the through hole 106. However, in the present embodiment, priority is given to preventing misrecognition of the QR code (registered trademark) 108 rather than suppressing a change in the resistance value of the wiring pattern, and the through hole 106 is not formed in the placement prohibition region 122. I have to.

  Although the QR code (registered trademark) 108 has been described as being formed by engraving, the present invention is not limited to this, and it may be formed by printing such as silk printing.

  In the case of silk printing, a through hole can be formed if it is separated from the printing place by several hundred μm according to the design rule. Therefore, the through hole 106 can be physically formed in the arrangement prohibited region 122. For this reason, if the formation of the through hole 106 is allowed also in the arrangement prohibition region 122, the degree of freedom in designing the arrangement position of the QR code (registered trademark) 108 and the through hole 106 is increased. However, even in the case of silk printing, the through hole 106 is not formed in the arrangement prohibited region 122 in order to prevent the through hole 106 from being mistakenly regarded as a part of the QR code (registered trademark) 108.

  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 the above-described embodiment, the identification symbol is the QR code (registered trademark) 108 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) 108 is used. It may be.

  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 the above-described embodiment, the entire QR code (registered trademark) 108 placement area 121 is on the ground wiring pattern 104 which is a single solid wiring pattern, and each side of the placement area 121 is the wiring pattern 104. Although it is made not to touch the circumference | surroundings, it is not limited to this, For example, what is described in following (1)-(3) may be used.

  (1) All of the arrangement region 121 of the QR code (registered trademark) 108 is a single solid wiring pattern on a power supply wiring pattern whose potential is a predetermined value (VDD), and is perpendicular to the back surface 100 b of the substrate 100. Each side of the arrangement region 121 may not be in contact with the periphery of the power supply wiring pattern in a plan view when the back surface 100b is viewed from the direction.

  (2) The entire arrangement area 121 of the QR code (registered trademark) 108 may be arranged on one wiring pattern other than the solid wiring pattern.

  (3) In a plan view of the back surface 100b viewed from a direction perpendicular to the back surface 100b of the substrate 100, at least one side of the solid wiring pattern in which the entire arrangement region 121 of the QR code (registered trademark) 108 is disposed and the back surface 100b In the case where another wiring pattern does not exist with the side closest to the side, the side of the arrangement region 121 of the QR code (registered trademark) 108 may be in contact with the side.

  In the above-described embodiment, the substrate 100 is placed on a predetermined wall in the housing 3 so that an unauthorized person cannot easily access or view the QR code (registered trademark) 108. In the attached state, the rear surface 100b on which the QR code (registered trademark) 108 is disposed is made to face the predetermined wall, or the QR code (registered trademark) 108 is imprinted at a predetermined depth that is difficult to visually recognize. However, either one may be used from the viewpoint of preventing unauthorized persons from easily accessing or viewing the QR code (registered trademark) 108.

  In the above-described embodiment, the QR code (registered trademark) 108 is disposed on the back surface 100b side where the components of the substrate 100 are not disposed. However, the present invention is not limited to this, and as illustrated in FIG. In addition, the board 200 (main control board 63, sub control board 73) may be arranged on the surface 200a side where the components are arranged. In this case, among a plurality of components including the components 203A, 203B, and 203C mounted on the surface 200a (among the components, the component 203B is the component having the highest height from the surface 200a), a QR code (registered trademark) ) It is preferable that the component closest to 208 be any one other than the component 203B having the highest height from the surface 200a. In this way, when reading the QR code (registered trademark) 208 with a reader, the QR code (registered trademark) 208 is greatly blurred due to focusing on the component, and the QR code (registered trademark) 208 is read correctly. Can be prevented from becoming impossible.

  Hereinafter, a case where the QR code (registered trademark) 208 is arranged on the surface 200a side of the substrate 200 will be described with reference to FIG.

(Refer to (a) and (b)). Further, a through hole 210 is formed in the substrate 200 to connect the power supply wiring pattern 209 disposed on the front surface 200a and the power supply wiring pattern disposed on the back surface 200b (see FIG. 5A). ). Further, a through hole 207 for connecting the signal wiring pattern 202 arranged on the front surface 200a and the signal wiring pattern arranged on the back surface 200b is formed in the substrate 200 (FIG. 5A). reference).

  In addition, a QR code (registered trademark) 208 that can read the identification information of the substrate 200 by using a reader on the surface 200a of the substrate 200 has a predetermined depth that is difficult to visually recognize on the wiring pattern 201 using a laser marker. It is formed by imprinting (for example, 100 μm).

  The arrangement area 221 of the QR code (registered trademark) 208 has a rectangular shape surrounded by a dotted line in FIG. 5A, and the entire arrangement area 221 of the QR code (registered trademark) 208 is a single solid wiring pattern. Each side of the arrangement region 221 is not in contact with the periphery of the wiring pattern 201 in a plan view when the surface 200a is viewed from a direction perpendicular to the surface 200a of the substrate 200. In addition, a through hole 206 exists in the arrangement prohibition area 222 surrounded by the one-dot chain line in FIG. 5A including the arrangement area 221 of the QR code (registered trademark) 208 and a predetermined adjacent area adjacent to the arrangement area 221. Absent.

  It should be noted that the marking depth of the QR code (registered trademark) 208 and the size of the adjacent area can be determined in the same manner as described in the embodiment, for example.

  The QR code (registered trademark) 208 is a component other than the component 203B having the highest height from the surface 200a, the component closest to the QR code (registered trademark) 208 among the plurality of components 203A and 203B mounted on the surface 200a. It is arranged so as to be the part 203A.

  It should be noted that a part whose height from the surface 200a is a predetermined value or more or a specific part that is likely to be a predetermined value or more (specifically, a one-way insertion mounting type used in some capacitors, filters, ICs, or the like) The QR code (registered trademark) 208 may not be arranged within a predetermined distance from the TO package.

  As shown in FIG. 5, when the QR code (registered trademark) 208 is disposed on the surface 200a side of the substrate 200 where the components 203A, 203B, 203C and the connector 215 are disposed, the QR code (registered trademark) 208 is It is preferable not to arrange it around the connector 215. In this case, reading of the QR code (registered trademark) 208 by the reader can be prevented from being obstructed by the connector 215, and the QR code (registered trademark) 208 is greatly blurred due to the focus of the reader being adjusted to the harness.
