Description

  The present invention relates to a gaming machine that prevents fraud such as board replacement.

  2. Description of the Related Art Conventionally, there is a pachinko gaming machine in which, when a game ball wins a starting opening provided on a game board, a jackpot lottery is performed and three symbols (for example, numbers) are variably displayed on a predetermined image display unit. When such a pachinko gaming machine is won, the three symbols displayed in a variable manner are stopped in a specific combination (for example, a so-called “zolo” such as “7, 7, 7”). After that, it becomes a jackpot game state, and the big prize opening on the game board is opened. During this time, the player can obtain a large number of prize balls by winning the game balls in the big prize opening.

  In such a pachinko gaming machine, the main control unit on the main control board performs a lottery lottery. Conventionally, an illegal board is attached to the main control board, a so-called hanging board, the main control board is replaced with a special board, or the CPU or ROM (Read Only Memory) of the main control board is replaced with an illegal one. Such as cheating.

  For example, if a regular main control board to be used for playing a game is replaced with a special main control board with frequent jackpots, many jackpots will occur and a large number of balls will be obtained illegally. In order to prevent such an illegal act, the main control board is configured so as not to be in contact with the case. In addition, in order to confirm that the main control board is a regular main control board, a stamp (seal) indicating that it is a regular product is attached to the case.

  If the seal is a mere seal, the fraudulent act will be overlooked if the seal itself is an illegitimate product that cannot be distinguished from a regular product. For example, since a seal peeled off from another collected gaming machine may be used, the seal itself is required to have a more functional configuration. For example, an IC chip (RF tag) is provided on a seal, and identification information (for example, model name, lot, serial number, etc.) that is a genuine product is stored in the IC chip.

  In the illegal product check, the front face of the pachinko machine is opened, and the IC chip identification information is read from the back by the IC reader provided in the inspection device. The information held in advance matches the read IC chip identification information. In this case, if it does not match, it can be determined that the IC chip is an unauthorized IC chip, and an unauthorized main control board can be detected. There is a pachinko gaming machine that uses such an IC chip to discriminate fraud (see, for example, Patent Document 1 below).

JP 2005-143641 A

  However, in the above-described prior art, there is a problem that a reader for reading an IC chip is expensive and it takes a cost to detect a regular product. Further, the case is made of a transparent body with a good visibility so that the main control board accommodated in the interior can be visually confirmed from the outside, and there is a restriction that it is impossible to arrange anything that obstructs the visibility of the inside. In addition, not only the main control board but also the effect control board that controls the contents of the effect, if it is illegally exchanged, the interests of the game will change.

  An object of the present invention is to provide a gaming machine in which the legitimacy of a control board can be confirmed inexpensively and easily and illegal actions such as board replacement can be prevented in order to eliminate the problems caused by the above-described conventional technology. To do.

  In order to solve the above-described problems and achieve the object, the present invention employs the following configuration. Reference numerals in parentheses indicate correspondence with the embodiments in order to facilitate understanding of the present invention, and do not limit the scope of the present invention. A gaming machine (100) according to the present invention seals a control board (151) for controlling the gaming machine (100) and the control board (151) and accommodates the control board (151) therein.

As shown in FIG. 3, the control unit 200 of the pachinko gaming machine 100 includes a main control unit 201 that controls the progress of the game, an effect control unit 202 that controls the contents of the effect by the image display unit 104, and awarding of prize balls And a prize ball control unit 203 for controlling. The configuration of each control unit will be described in detail below.

(1. Main control unit)
The main control unit 201 includes a CPU (Central Processing Unit) 211, a ROM (Read Only Memory) 212, a RAM (Random Access Memory) 213, an input / output interface (I / O) (not shown), and the like. The

  The main control unit 201 functions to control the progress of the game of the pachinko gaming machine 100 by executing various programs stored in the ROM 212 while the CPU 211 uses the RAM 213 as a work area. Specifically, the main control unit 201 performs a winning lottery, a normal symbol lottery, a game state setting, and the like, and controls the progress of the game. The main control unit 201 is realized by the main control board 151.

  The CPU 211 executes basic processing as the game content progresses based on various programs stored in the ROM 212 in advance. The ROM 212 stores a hold storage program, a winning determination program, a symbol determination program, a variation pattern selection program, a special diagram variation display program, a special winning opening control program, a game state setting program, and the like.

  The hold storage program is a program for storing the game ball detected by the first start port SW221 as a special 1 hold ball and storing the game ball detected by the second start port SW222 as a special 2 hold ball. The hit determination program is a program that makes a big hit determination and a small hit determination for the special 1 holding ball and the special 2 holding ball at the start of the variation of the special symbol.

  There are two types of jackpots: a long hit with a large number of rounds and a large number of winning balls, and a short hit with a small number of rounds and a small number of winning balls. In the hit determination for the special 2 reserved ball, it is easier to win the long win that is advantageous to the player than the hit determination for the special 1 reserved ball. The small hit is a special game for opening the winning prize opening 109 for a short time, and is for changing the variation pattern table in which the variation pattern is stored.

  The symbol determination program is a program for determining a jackpot symbol (a symbol per probability variation length, a symbol per normal length, a symbol per high probability short) in the case of a jackpot. The variation pattern selection program is a program for selecting a variation pattern indicating a variation mode from the variation start to the variation stop of the special symbol according to the winning symbol. The special figure fluctuation display program is a program that variably displays special symbols using the fluctuation pattern selected by executing the fluctuation pattern selection program.

  The big prize opening control program is a program for opening the big prize opening 109 with a predetermined opening time as one round according to the winning symbol at the time of big hit or small hit. There are long hits and short hits. The long win is, for example, a big hit that allows the player to win a lot of balls, with the round winning opening 109 being opened for 30 seconds as one round and the number of rounds being 15 rounds.

  The short hit is, for example, a big hit with a small number of balls, in which the winning opening 109 is opened for 30 seconds as one round and the number of rounds is two. The small hit is a specific lose represented by a special symbol different from a normal lose (a non-small hit), for example, 0.1 seconds × 1 time or 0.1 seconds × multiple times, It is a kind of losing with one round of opening.

  The gaming state setting program sets the gaming state after winning the hit to a low probability gaming state or a high probability gaming state according to the jackpot symbol, and also adds a gaming state (hereinafter referred to as “electric support game” to which an electric chew support function is added. This is a program for setting a game state (hereinafter referred to as “non-electric support game state”) to which the electric chew support function is not added. The electric chew support function is a function of shortening the normal symbol variation time and lengthening the opening time of the electric tulip 107.

  The low probability gaming state is a gaming state in which a big hit is unlikely to occur. The high probability gaming state is a gaming state in which a jackpot is likely to occur about 10 times as compared to the low probability gaming state. Here, each win and the game state after each win will be described with specific examples. The jackpots include per-probability length, normal per-length, and high-probability per hit. When winning per probability variation length, after the jackpot ends, the game shifts to a high probability electric support game state (hereinafter referred to as “probability variation game state”) to which an electric chew support function is added.

  When winning a normal long win, after the jackpot ends, the game shifts to a low-probability electric support game state (hereinafter referred to as “time-short game state”) to which an electric chew support function is added. When winning with high accuracy and short wins, a transition is made to a high probability non-electric support game state (hereinafter referred to as “high accuracy non-short game state”) to which the electric chew support function is not added.

  Further, the main control unit 201 includes various switches (SW) for detecting a game ball, a solenoid for opening and closing an electric accessory such as the special winning opening 109, the above-described special figure 1 display unit 112a, and special figure 2. A display unit 112b, a normal symbol display unit 113, a reserved ball display unit 114, and the like are connected.

  Specifically, the various SWs described above include a first start port SW221 that detects a game ball won in the first start port 105, and a second start port SW222 that detects a game ball won in the second start port 106. , A gate SW 223 that detects a game ball that has passed through the gate 108, a big winning opening SW 224 that detects a gaming ball that has won a prize winning opening 109, and a normal winning opening SW 225 that detects a gaming ball that has won a winning prize 110 Is connected to the main control unit 201.

  The detection results by the respective SWs (221 to 225) are input to the main control unit 201. A proximity switch or the like is used for these SWs. It should be noted that a plurality of the normal winning opening SW225 may be provided for each arrangement position of the normal winning opening 110.

  Further, as the solenoid, an electric tulip solenoid 231 that opens and closes the electric tulip 107 and a big prize opening solenoid 232 that opens and closes the big prize opening 109 are connected to the main control unit 201. The main control unit 201 controls driving of the solenoids (231 and 232).

  The CPU 251 executes image and sound generation and output processing. The ROM 252 stores programs for generating and outputting images and sounds, various image data such as background images, design images, character images, and warning images, various sound data, and the like. The RAM 253 functions as a work area for the CPU 251 and temporarily stores image data to be displayed on the image display unit 104 and audio data to be output from the speaker 254.

  That is, the image / sound control unit 202b executes image and sound control based on an instruction from the production control unit 202a by executing various programs stored in the ROM 252 while the CPU 251 uses the RAM 253 as a work area. Works like doing.

  For example, the CPU 251 executes various image processing and audio processing such as background image display processing, effect design variation / stop display processing, character image display processing, and sign hold display processing based on the instruction content instructed from the effect supervising unit 202a. To do. At this time, the CPU 251 reads image data and audio data necessary for processing from the ROM 252 and writes them in the RAM 253.

  Image data such as background images and effect design images written in the RAM 253 is output to the image display unit 104 connected to the image / sound control unit 202b, and is superimposed on the display screen of the image display unit 104. . That is, the effect design image is displayed so as to be seen in front of the background image. When the background image and the design image overlap at the same position, the design image is preferentially stored in the RAM 253 by referring to the Z value of the Z buffer of each image data by a known hidden surface removal method such as the Z buffer method. Remember me.

  The audio data written in the RAM 253 is output to the speaker 254 connected to the image / audio control unit 202b, and audio based on the audio data is output from the speaker 254.

  4 and 5, the main board case 151 a is partially covered by the back cover 154. The main board case 151a accommodates the main control board 151 so that unauthorized modification (fraud) such as connecting or replacing another board cannot be performed. Further, the main board case 151a is formed of a transparent case so that it is possible to visually confirm fraudulent acts such as modification of the main control board 151 and replacement with an unauthorized board. The effect board case 152a for accommodating the effect control board 152 and the power supply board case 153a for accommodating the power supply control board 153 shown in FIG. 2 are also transparent cases like the main board case 151a.

  The main substrate case 151 a has an opening 402 on the general surface 401. A stick-like operation unit 155 is inserted into the opening 402 so that the ram clear switch 151b provided on the main control board 151 can be pressed (pressed) using the operation unit 155. It has become. On the general surface 401 in the vicinity of the opening 402, an opening / closing part 156 that covers the opening 402 in an openable and closable manner is provided.

  The opening / closing part 156 includes a rotation shaft 157 and a locking piece 156a. The opening / closing part 156 is rotatable about a rotation shaft 157. Further, the opening / closing portion 156 can be held in a closed state by the locking piece 156a being locked to the locking portion 403 provided on the main board case 151a. 4 and 5 show a case where the opening / closing part 156 is in an open state.

  Also, a first certification seal 411 and a second certification seal 412 are affixed on the general surface 401 of the main board case 151a, and a third certification seal 413 is affixed to the side of the general surface 401 of the main board case 151a. Has been. The first certification seal 411 is a seal that is affixed at the time of manufacture by a manufacturer, for example, and proves that the main control board 151 is a legitimate product. The second certification seal 412 is a seal that certifies that the certification has been performed by a third party organization or a license / authorization organization.

  A two-dimensional code 412 a is printed on the second certification seal 412. The two-dimensional code 412a is an identifier that represents a numerical value, a character, or the like depending on the thickness of the striped line. For example, the two-dimensional code 412a represents a registration number of the pachinko gaming machine 100 in a third party organization or a licensed organization. The third certification seal 413 is made of a two-dimensional code and represents, for example, the product number of the CPU 211 and ROM 212 at the time of manufacture.

(Details of certification seal)
Next, details of the certification seals 411 to 413 will be described with reference to FIGS. FIG. 6 is an explanatory view showing details of the first certification seal 411. The first certification seal 411 has a colored printing surface 602 formed on a transparent film 601. The printing surface 602 may be a colored material that can be printed with the microdot code 603, but here, a light shielding material is used. On the printing surface 602, “CR Lucky 7” is displayed as a description portion for describing predetermined information, for example, by hollowing out. The predetermined information is, for example, a model name or a manufacturer name. The hollowing out means that the character portion is not printed and is transparent. On the printed surface 602, an invisible and fine micro dot code 603 is printed on a portion (a blank portion) other than a description portion where “CR lucky 7” is written. In other words, a layer shielded by the colored printing surface 602 is formed in the lower layer of the microdot code 603.

  The micro dot code 603 is obtained by coding information with a dot pattern, and the dot pattern is detected by a specific detection device. The micro dot code 603 includes information indicating only the presence / absence of a dot pattern, and does not include any special information. However, the micro dot code 603 includes a unique number determined on the main control board 151 such as a manufacturing number (LOT number). It is also possible to provide information. Further, the micro dot code 603 is not limited to the size and shape shown in the figure, and can be printed over the entire margin.

  For the microdot code 603, for example, colorless and transparent ink (stealth ink) that absorbs infrared rays is used. As the stealth ink, a non-carbon ink that does not interfere with the design of the printing surface 602 is used. The micro dot code 603 can be formed by adding only one dot printing to the normal printing process, and does not require any special printing technique. The micro dot code 603 can be printed at any place other than the transparent part. For example, the micro dot code 603 can generate about 65,000 types of dot patterns of 32 bits (about 4 billion) per 2 mm square, and can issue about 300 trillion unique codes. ing.

  FIG. 7 is an explanatory view showing details of the second certification seal 412. The second certification seal 412 has a two-dimensional code 412a printed on the surface of the colored seal 701, for example. The two-dimensional code 412a is obtained by coding information about the main control board 151 using white and black colors (that is, colored). For example, the pachinko gaming machine 100 in a third-party organization or a licensed organization is used. The registration number is encoded and expressed. If the information about the main control board 151 is coded using a plurality of different colors, the two-dimensional code 412a is not limited to using white and black, but using other colors. In addition, not only a two-dimensional code but also a one-dimensional barcode may be used.

  A micro dot code 603 is printed on the two-dimensional code 412a or on the margin 702 of the colored sticker 701. Here, the micro dot code 603 is printed on the second certification sticker 412, but not only on the sticker or the two-dimensional code 412 a, but on a colored part provided on the main board case 151 a. The micro dot code 603 may be printed. Specifically, for example, an opaque resin portion may be provided on the main substrate case 151a, and the microdot code 603 may be formed thereon. The micro dot code 603 includes information indicating only the presence / absence of a dot pattern. The micro dot code 603 does not include information, but may include information similar to the two-dimensional code 412a, for example. .

  FIG. 8 is an explanatory view showing details of the third certification seal 413. The third proof seal 413 has a colored two-dimensional code 413 a printed on the surface of the seal 801. This two-dimensional code 413a is obtained by coding information on the main control board 151 using white and black colors (that is, colored). For example, product numbers such as the CPU 211 and the ROM 212 at the time of manufacture are coded. It has been done. A micro dot code 603 is printed on the two-dimensional code 413a. If the information about the main control board 151 is coded using a plurality of different colors, the two-dimensional code 413a is not limited to using white and black, but using other colors. In addition, not only a two-dimensional code but also a one-dimensional barcode may be used.

  Here, the microdot code 603 is printed on the two-dimensional code 413a. However, the microdot code 603 is not limited to the two-dimensional code 413a but is applied to a colored portion provided on the main substrate case 151a. May be printed. In addition, the micro dot code 603 includes information indicating only the presence or absence of a dot pattern. The micro dot code 603 includes no information. However, the micro dot code 603 can include information similar to the two-dimensional code 413a, for example. It is.

  In addition, the first certification seal 411 to the third certification seal 413 are attached from the outside of the main board case 151a. However, the present invention is not limited thereto, and may be attached from the inside of the main board case 151a. Good.

(Overview of detection method)
Next, an example of a technique for detecting the microdot code 603 will be described with reference to FIG. FIG. 9 is an explanatory diagram showing an example of a method for detecting the microdot code 603. In FIG. 9, the detection device 900 includes a grip portion 901 that is formed in a shape that can be easily picked up by a hand and a reading portion 910 provided at an end of the grip portion 901. The reading unit 910 includes an irradiation unit 911, a light receiving sensor 912, and a lens 913.

  The irradiation unit 911 includes an infrared LED, and irradiates the first certification seal 411 with infrared rays having a predetermined wavelength, for example. The light receiving sensor 912 receives reflected light through the lens 913. As the light receiving sensor 912, for example, a CMOS (Complementary Metal Oxide Semiconductor) image sensor is used. The detection device 900 reads the microdot code 603 by analyzing the received light. When reading the micro dot code 603, the reading unit 910 and the micro dot code 603 may be brought into contact with each other for reading, or may be read without contact.

(Functional configuration of detection device)
Next, the functional configuration of the detection apparatus 900 will be described with reference to FIG. FIG. 10 is a block diagram illustrating a functional configuration of the detection apparatus 900. In FIG. 10, the detection apparatus 900 includes an irradiation unit 911, a light receiving sensor 912, a power supply SW 1011, a processing unit 1000, and an output unit 1012.

  The power source SW 1011 is switched ON / OFF by being operated by a player. When the power source is turned on, the irradiation unit 911 emits infrared rays. When the power source is turned off, the irradiation unit 911 emits infrared rays. Stops. The processing unit 1000 includes a detection unit 1001 and a determination unit 1002. The detection unit 1001 detects light received by the light receiving sensor 912. The determination unit 1002 analyzes the light detected by the detection unit 1001 and determines the presence or absence of the microdot code 603.

  When the micro dot code 603 is present, the determination unit 1002 causes the speaker 1013 of the output unit 1012 to output sound. Note that the determination unit 1002 may not output sound from the speaker 1013 when the microdot code 603 exists, and may output sound from the speaker 1013 when the microdot code 603 does not exist. In addition, the output method by the output unit 1012 is not limited to audio output. When the detection apparatus 900 includes a display or when an external display is connected to the detection apparatus 900, these displays are used. Display output is also possible, and the output method is not limited.

(Timer interrupt processing)
Next, the contents of the timer interrupt process performed by the main control unit 201 will be described with reference to FIG. FIG. 11 is a flowchart showing the processing contents of the timer interrupt processing performed by the main control unit 201. The timer interrupt process is a process that interrupts the main control process executed by the main control unit 201 every predetermined period (for example, 4 ms) during the power supply period.

  In FIG. 11, the CPU 211 of the main control unit 201 performs a random number update process (step S1101). The random number update process is a process for updating each random number by incrementing each random number such as a jackpot random number, a jackpot symbol random number, a reach random number, or the like.

  Thereafter, the first start port 105 or the second start port 106 is subjected to a switch process at the time of winning a prize (step S1102). The switch process includes a gate SW process for obtaining a random number every time a game ball is detected by the gate SW 223, and a game ball detected by the first start port SW221 or the second start port SW222, which will be described later with reference to FIG. There is a start port SW process for acquiring a random number every time.

  Thereafter, symbol processing is performed (step S1103). The symbol processing includes symbol processing for performing a normal symbol hit determination using random numbers acquired in the gate SW processing, and special symbol processing described later with reference to FIG. Further, an electric accessory process is performed (step S1104). The electric accessory process includes an electric chew process for operating the electric tulip 107 and a special winning opening process for operating the special winning opening 109. Thereafter, a prize ball process is performed (step S1105), and these output processes are performed (step S1106).

(Start-up SW processing)
Next, the processing contents of the start port SW process performed by the main control unit 201 will be described with reference to FIG. FIG. 12 is a flowchart showing the processing contents of the start port SW processing performed by the main control unit 201. The start port SW process is a process content included in the switch process shown in step S1102 of FIG.

  In FIG. 12, the CPU 211 of the main control unit 201 determines whether or not the first start port SW221 of the first start port 105 is ON (step S1201). When the first start port SW221 is OFF (step S1201: No), the process proceeds to step S1207. When the first start port SW221 is ON (step S1201: Yes), it is determined whether or not the count value U1 of the first start port detection counter that has counted the number of detections of the first start port SW221 is smaller than “4”. (Step S1202).

  When the count value U1 is “4” (step S1202: No), the process proceeds to step S1207. When the count value U1 is smaller than “4” (step S1202: Yes), “1” is added to the count value U1 (step S1203). Then, the random number is acquired, and the acquired random number is stored in the RAM 213 (step S1204). The random number is a jackpot random number, a design random number, a variation pattern random number, or the like. The hit random numbers are used to determine any one of the big hit, the small hit, and the loss. For example, there are 400 “0” to “399”, and one of them is randomly acquired.

  The design random number is for determining the type of jackpot (per probability variation length, per normal length, per high probability short) and the type of jackpot (small hits A to C), for example, “0” to “249”. There are 250 of these, one of which is randomly acquired. Each acquired random number is stored in the RAM 213.

  The fluctuation pattern random number is for determining the fluctuation pattern, and there are 300, for example, “0” to “299”, and one of these is randomly acquired. The RAM 213 has a first storage unit for four reserved balls by winning the first start port 105. The first storage unit stores information that the winning is made to the first start port 105, information on the jackpot random number, symbol random number, variation pattern random number, and the like.

  Thereafter, a preliminary determination process is performed (step S1205). The pre-determination process uses the hit random number acquired in step S1204 to determine whether the hit is a big win, a small win or a loss. In the prior determination process, in addition to the hit determination, a design random number determination using a design random number and a variation pattern determination using a variation pattern random number are also performed.

  Thereafter, a first reserved ball number increase command is set to indicate that the number of reserved balls has increased due to winning at the first starting port 105 (step S1206). The set command is output to the image / sound control unit 202b and the lamp control unit 202c by the output process shown in step S1106 of FIG.

  Then, it is determined whether or not the second start port SW222 of the second start port 106 is ON (step S1207). If the second start port SW222 is OFF (step S1207: No), the process is terminated as it is. If the second start port SW222 is ON (step S1207: Yes), it is determined whether or not the count value U2 of the second start port detection counter that has counted the number of detections of the second start port SW222 is smaller than “4”. (Step S1208).

  When the count value U2 is “4” (step S1208: No), the processing is ended as it is. When the count value U2 is smaller than “4” (step S1208: Yes), “1” is added to the count value U2 (step S1209). Each random number is acquired, and the acquired random number is stored in the RAM 213 (step S1210). The RAM 213 has a second storage unit for four reserved balls by winning the second start port 106. The second storage unit stores information that the winning is made to the second starting port 106, a winning random number, a design random number, a variation pattern random number, and the like.

  Thereafter, a preliminary determination process is performed (step S1211). In the pre-determination process, a reach random number determination using a reach random number is performed in addition to a hit determination using the hit random number acquired in step S1210 and a design random number determination using a design random number. Thereafter, a second reserved ball number increase command indicating that the number of reserved balls has increased due to winning at the second starting port 106 is set (step S1212). The set command is output to the image / sound control unit 202b and the lamp control unit 202c by the output process shown in step S1106 of FIG.

(Special symbol processing)
Next, the contents of the special symbol processing performed by the main control unit 201 will be described with reference to FIG. FIG. 13 is a flowchart showing the contents of special symbol processing performed by the main control unit 201. This special symbol process is a process content included in the symbol process of step S1103 shown in FIG.

  In FIG. 13, the CPU 211 of the main control unit 201 determines whether or not a winning game flag indicating that a winning game is being played is ON (step S1301). The winning game flag is a flag that is set to ON when the stopped special symbol is a symbol indicating a big hit or a small hit in the stop process shown in step S1314.

  If the winning game flag is ON (step S1301: Yes), the process is terminated as it is. If the winning game flag is not ON (step S1301: No), it is determined whether or not the special symbol is changing (step S1302). If the special symbol is changing (step S1302: Yes), step S1311 is determined. Migrate to If the special symbol is not changing (step S1302: No), whether or not the count value U2 of the second start port detection counter as the reserved number of game balls won in the second start port 106 is “1” or more. Is determined (step S1303).

  When the count value U2 is “1” or more (step S1303: Yes), a value obtained by subtracting one count value U2 is set as the new number of reserved balls (step S1304), and the process proceeds to step S1307. In step S1303, if the count value U2 is not equal to or greater than “1” (step S1303: No), that is, if “U2 = 0”, the first start as the number of game balls held in the first start port 105 is held. It is determined whether or not the count value U1 of the mouth detection counter is “1” or more (step S1305).

  If the count value U1 is not equal to or greater than “1” (step S1305: No), that is, if “U1 = 0”, the process ends. When the count value U1 is “1” or more (step S1305: Yes), a value obtained by subtracting one count value U1 is set as the new number of held balls (step S1306), and the process proceeds to step S1307. In step S1307, a hit determination process is performed (step S1307).

  The details of the winning determination process will be described later with reference to FIG. 14, but the winning random number acquired when the game ball wins the first starting opening 105 or the second starting opening 106 is a big hit random number or a small hitting preset value. This is a process of determining whether or not the winning random number is matched.

  As shown in steps S1303 to S1306, the game ball won at the second start port 106 is digested earlier than the game ball won at the first start port 105. This is because in the determination of the jackpot symbol when winning the second starting port 106, a determination that is advantageous to the player is made, and specifically, because the winning is not won in the high accuracy short win. It is.

  Thereafter, variation pattern selection processing is performed (step S1308). This variation pattern selection process is a process of selecting a variation pattern of a special symbol using the determination result of the hit determination process or the variation pattern random number.

  Then, the variation of the special symbol is started (step S1309). Further, a change start command is set in the RAM 213 (step S1310). Then, it is determined whether or not the variation time of the special symbol has passed the variation time selected by the variation pattern selection process (step S1311). If the fluctuation time has not elapsed (step S1311: No), the process is terminated as it is.

  When the variation time has elapsed (step S1311: Yes), the variation of the special symbol is stopped (step S1312), and a variation stop command is set (step S1313). Then, the stop process is executed (step S1314), and the process ends. Stopped process is a process that sets the hit game flag to ON when the special symbol that is stopped indicates a win, or sets the short-time game flag indicating the short-time game state to OFF according to the number of remaining short-time games It is.

(Winning judgment process)
Next, the content of the hit determination process shown in step S1307 of FIG. 13 will be described with reference to FIG. FIG. 14 is a flowchart showing the processing content of the hit determination processing performed by the main control unit 201.

  In FIG. 14, the CPU 211 of the main control unit 201 determines whether or not the high probability flag indicating the high probability gaming state is ON (step S1401). The high probability flag is a flag that is set to ON in accordance with the jackpot symbol in the setting of the gaming state at the end of the hit. When the high probability flag is OFF (step S1401: No), a low probability hit determination table described later with reference to FIG. 15 is set (step S1402).

  When the high probability flag is ON (step S1401: Yes), a high probability hit determination table described later with reference to FIG. 16 is set (step S1403). Thereafter, using the set hit determination table and the hit random number acquired in the start port SW process (see FIG. 12), a hit random number determination process is performed to determine whether it is a big hit or a small hit (step S1404).

  Then, it is determined whether or not the result of the hit random number determination process is a big hit (step S1405). When it is determined that it is a big hit (step S1405: Yes), it is determined whether or not it is a big hit random number determination for the count value U1 indicating the number of special 1 reserved balls (step S1406). In the case of jackpot random number determination for the count value U1 indicating the number of special 1 reserved balls (step S1406: Yes), the first start-up jackpot symbol determination table is set (step S1407). Details of the first start opening jackpot symbol determination table will be described later with reference to FIG.

  On the other hand, if it is not the jackpot random number determination for the count value U1 in step S1406 (step S1406: No), that is, if it is the jackpot random number determination for the count value U2 indicating the number of special 2 reserved balls, the second start opening jackpot symbol A determination table is set (step S1408). Details of the second start-up jackpot symbol determination table will be described later with reference to FIG.

  Thereafter, a jackpot symbol random number determination process for determining a jackpot symbol is performed using the set jackpot symbol determination table (step S1409). Then, the jackpot symbol is set (step S1410), and the process is terminated. If it is determined in step S1405 that the result of the hit random number determination process is not a big hit (step S1405: No), it is determined whether the result of the hit random number determination process is a small hit (step S1411). When it is determined that it is a small hit (step S1411: Yes), a small hit symbol determination table is set (step S1412).

  Thereafter, a small hit symbol random number determination process for determining the small hit symbol is performed using the set small hit symbol determination table (step S1413). Then, a small hit symbol is set (step S1414), and the process is terminated. In step S1411, if it is not a small hit (step S1411: No), a lost symbol is set (step S1415), and the process is terminated.

(An example of the low probability hit determination table)
Next, the low-probability hit determination table set in step S1402 of FIG. 14 will be described with reference to FIG. FIG. 15 is an explanatory diagram showing an example of the low probability hit determination table. In FIG. 15, the low probability hit determination table 1500 shows the ratio selected for big hit or small hit.

  The jackpot is selected at a ratio of “1/400”. Specifically, out of the random number values “0 to 399” that can be acquired, when “3” is acquired, it is a big hit. On the other hand, the small hit is selected at a ratio of “4/400”. Specifically, out of the random number values “0 to 399” that can be acquired, when “396 to 399” is acquired, it is a small hit. It should be noted that the ratio selected for the small hits shown in the low probability hit determination table 1500 is the one when the special figure 1 fluctuates, and the percentage selected for the small hits when the special figure 2 fluctuates is almost selected. It is a ratio (for example, “1/400”).

  Here, if an illegal act such as replacing the main control board 151 with a special board or replacing the CPU 211 or ROM 212 of the main control board 151 with an illegal one is performed, the ratio of jackpot is “1/400”. It may be illegally changed to a different ratio (for example, “10/400”, etc.). Such an unauthorized change is also the same in the high probability hit determination table described below with reference to FIG.

(Example of high probability hit determination table)
Next, the high probability hit determination table set in step S1403 of FIG. 14 will be described with reference to FIG. FIG. 16 is an explanatory diagram showing an example of the high probability hit determination table. In the high probability hit determination table 1600 shown in FIG. 16, the jackpot is selected at a ratio of “10/400”. That is, in the high probability gaming state, it is easier to win the jackpot by about 10 times compared to the low probability gaming state (low probability jackpot determination table 1500).

  The small hits are selected at a ratio of “4/400” as in the low probability hit determination table 1500. It should be noted that the ratio selected for the small hits shown in the high probability hit determination table 1600 is the one when the special figure 1 fluctuates, and the percentage selected for the small hits when the special figure 2 fluctuates is almost selected. It is a ratio (for example, “1/400”).

(Example of jackpot symbol determination table)
Next, the jackpot symbol determination table set in step S1407 and step S1408 in FIG. 14 will be described with reference to FIGS. FIG. 17 is an explanatory diagram showing an example of a first start-up jackpot symbol determination table. The first start opening jackpot symbol determination table 1700 shown in FIG. 17 is a table used in the case of winning a jackpot by winning the first starting opening 105 as a result of the winning random number determination processing (see step S1404 in FIG. 14). is there.

  The first start opening jackpot symbol determination table 1700 shown in FIG. 17 shows the ratio of each symbol (normal symbol per length, symbol per probability variation length, symbol per high probability short) selected. The normal long win symbol is a jackpot symbol that sets a low-probability electric support game state (time-short game state) to which an electric chew support function is added after the jackpot game ends.

  The probability variation per symbol is a jackpot symbol for setting a high-probability electric support game state (probability variation game state) to which an electric chew support function is added after the end of the jackpot game. The high-accuracy short win symbol is a jackpot for setting a high-probability non-electric support game state (high-accuracy non-short-time game state) to which the electric chew support function is not added after the jackpot game ends. In the first start-up jackpot symbol determination table 1700, the symbol per normal length is selected at a ratio of “50/250”, and the symbol per probability variation length and the symbol per high-accuracy short are selected at a ratio of “100/250”, respectively. It is like that.

  Here, if an illegal act such as replacing the main control board 151 with a special board or replacing the CPU 211 or ROM 212 of the main control board 151 with an illegal one, the ratio of each symbol is illegally changed to a different ratio. Subject to change. Such an unauthorized change is the same in the second start-up jackpot symbol determination table described below with reference to FIG.

  FIG. 18 is an explanatory diagram showing an example of a second start-up jackpot symbol determination table. The second start opening jackpot symbol determination table 1800 shown in FIG. 18 is a table used in the case of winning a jackpot by winning the second start opening 106 as a result of the winning random number determination processing (see step S1404 in FIG. 14). is there. The second start-up jackpot symbol determination table 1800 shown in FIG. 18 shows the proportion of each symbol selected.

  In the second start-up jackpot symbol determination table 1800, the symbol per normal length is selected at a rate of “50/250” and the symbol per probability variation length is selected at a rate of “200/250”, while the symbol per high probability is selected. It is not selected. That is, the determination of the jackpot symbol for the game ball won at the second starting port 106 is more advantageous to the player than the jackpot symbol determination for the game ball won at the first starting port 105 (the symbol per probability variation length). It is easier to win. That is, in a gaming state to which an electric chew support function is added, such as a probable gaming state, it is easy to win a jackpot advantageous to the player, and it is possible for the player to acquire a large number of balls.

(Power SW processing performed by the detection device)
Next, a power SW process performed by the detection device 900 will be described with reference to FIG. FIG. 19 is a flowchart showing power SW processing performed by the detection apparatus 900. In FIG. 19, the detection apparatus 900 waits until the power SW 1011 is turned on (step S1901: No loop). When the power SW 1011 is turned on (step S1901: Yes), the irradiation unit 911 emits infrared rays (step). S1902), the process ends.

(Dot pattern detection processing performed by the detector)
Next, a dot pattern detection process performed by the detection apparatus 900 will be described with reference to FIG. FIG. 20 is a flowchart showing a dot pattern detection process performed by the detection apparatus 900. In FIG. 20, the detection device 900 receives the reflected infrared light emitted from the light receiving sensor 912 by the irradiation unit 911 (step S2001). Then, the received light is analyzed (step S2002).

  As a result of the analysis, it is determined whether a dot pattern has been detected (step S2003). If a dot pattern is not detected (step S2003: No), the process ends as it is. When a dot pattern is detected (step S2003: Yes), a notification sound is output from the speaker 1013 (step S2004), and the process ends. That is, as shown in FIG. 9, when the operator operates the detection device 900 to bring the reading unit 910 close to the micro dot code 603 of the first certification seal 411 and the micro dot code 603 is detected, for example, The notification sound is output. The time required for analysis from light reception by the light receiving sensor 912 is only 0.1 to 0.2 seconds.

  In the above-described processing, as shown in step S2003, only the presence / absence of a dot pattern is determined. However, the present invention is not limited to this, and the microdot code 603 is provided with unique information of the main control board 151 and the like. The information may be stored in the detection device 900, and the detection device 900 may make a match determination. In the case of such a configuration, a notification sound may be output when the match determination results match.

  As described above, in the first embodiment, invisible on the colored portion (printing surface 602) of the colored seal (first certification seal 411) attached to the transparent main substrate case 151a that houses the main control substrate 151. A microdot code 603 provided with a simple dot pattern was provided. Therefore, the legitimacy of the main control board 151 can be easily confirmed with an inexpensive configuration, and illegal actions such as board replacement can be prevented.

  In the first embodiment, the micro dot code 603 is provided on the information sticker (first certification sticker 411) provided with a colored part on which predetermined information (for example, model name) is written on the transparent part. Therefore, the microdot code 603 can be provided without providing a separate seal, that is, the seal that is normally used. Therefore, the legitimacy of the main control board 151 can be easily confirmed without reducing the visibility inside the main board case 151a.

  Further, in the first embodiment, since the micro dot code 603 is provided on the blank portion of the information sticker (the first certification sticker 411) excluding the description portion where the predetermined information is written, the check by the operator is performed. Can be made easier. In particular, as in the first embodiment, in the case where characters are represented by hollowing out from the viewpoint of not hindering visibility, the microdot code 603 cannot be provided in the hollowing out part, so that the blank portion Printed on top. Further, since the light shielding material is used for the printing surface 602, the accuracy of reading the micro dot code 603 by the detection device 900 can be improved without the printing surface 602 being transmitted.

  Further, in the first embodiment, the opaque colored portion provided on the main board case 151a (on the two-dimensional code 412a of the second certification seal 412 and the margin 702, or on the two-dimensional code 413a of the third certification seal 413). ) Was provided with a microdot code 603. Therefore, as with the first proof seal 411 having the micro dot code 603, it is possible to easily confirm the legitimacy of the main control board 151 with an inexpensive configuration, and to perform illegal actions such as board replacement. Can be prevented.

  In the first embodiment, since the micro dot code 603 is provided on the two-dimensional codes 412a and 413a, information by the micro dot code 603 is further added without disturbing reading of the two-dimensional codes 412a and 413a. be able to.

  Furthermore, in the first embodiment, since invisible stealth ink is used, any non-transparent portion on the main board case 151a that requires visibility, for example, a photo, an illustration, a text, etc. A dot pattern can be printed at the position. That is, new information (microdot code 603) can be provided without hindering the visibility of the main substrate case 151a.

  Further, since the operator can grasp the presence or absence of the micro dot code 603 simply by holding the detection device 900 and bringing the reading unit 910 close to the area where the dot pattern is printed, the operation can be performed very easily. Moreover, since it takes only 0.1 to 0.2 seconds from light reception to analysis, it can be checked in a short time. As a result, it is possible to check whether or not the main control board 151 has been illegally replaced without burdening the operator during daily inspections.

  Furthermore, since the dot pattern uses stealth ink that reacts in the infrared region, even if the proof seals 411 to 413 are duplicated, it is difficult to assume that the dot pattern is duplicated, and it is proud of high security. it can.

  In the first embodiment described above, an example has been described in which a dot pattern is printed on the certification stickers 411 to 413 that are affixed to the main board case 151a. However, it is affixed to the effect board case 152a and the power board case 153a. A dot pattern may be printed on a sticker or an impermeable part that can be detected by the detection device 900. With such a configuration, it is possible to easily detect the presence / absence of an unauthorized board change even on the production control board, the power supply control board 153, and the like. Furthermore, the present invention is applicable to any transparent case that accommodates a control board, not limited to the production board case 152a and the power supply board case 153a.

(Embodiment 2)
Next, a second embodiment according to the present invention will be described. The second embodiment is different from the first embodiment in that a plurality of microdot codes having different information are used. In the following, the points described in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

(Details of certification seal)
FIG. 21 is an explanatory diagram illustrating details of the certification seal according to the second embodiment. In FIG. 21, similarly to the first certification seal 411 of the first embodiment, the certification seal 2100 has a colored printing surface 602 made of, for example, a light shielding material on the transparent film 601. On the printed surface 602, invisible and fine microdot codes 2101 and 2102 are printed on portions (margin portions) other than the portion where “CR Lucky 7” is written. The first microdot code 2101 includes information A by, for example, a first dot pattern, and the second microdot code 2102 includes information B by, for example, a second dot pattern. The information A and the information B may be different information that can be read by the detection device 900, respectively.

(Functional configuration of detection device)
Next, the function of the determination unit 1002 (see FIG. 10) of the detection apparatus 900 according to the second embodiment will be described. In Embodiment 2, the determination unit 1002 analyzes the light detected by the detection unit 1001 and determines whether it is the first microdot code 2101 (information A) or the second microdot code 2102 (information B). When the information A is determined and the information B is determined, the sound is output from the speaker 1013.

(First micro dot code detection process performed by the detection device)
Next, a first microdot code detection process performed by the detection apparatus 900 will be described with reference to FIG. FIG. 22 is a flowchart showing a first microdot code detection process performed by the detection apparatus 900. In FIG. 22, the detection apparatus 900 receives the infrared reflected light emitted from the light receiving sensor 912 by the irradiation unit 911 (step S <b> 2201). Then, the received light is analyzed (step S2202).

  As a result of the analysis, it is determined whether or not a first dot pattern (first microdot code 2101) has been detected (step S2203). If the first micro dot code 2101 is not detected (step S2203: No), the process is terminated as it is. When the first microdot code 2101 is detected (step S2203: Yes), that is, when the information A is detected, the detection flag indicating that the first microdot code 2101 is detected is turned ON (step S2204). The process ends.

(Second micro dot code detection process performed by the detection device)
Next, the second microdot code detection process performed by the detection apparatus 900 will be described with reference to FIG. FIG. 23 is a flowchart showing a second microdot code detection process performed by the detection apparatus 900. In FIG. 23, the detection apparatus 900 receives the reflected infrared light emitted from the light receiving sensor 912 by the irradiation unit 911 (step S2301). Then, the received light is analyzed (step S2302).

  As a result of the analysis, it is determined whether or not a second dot pattern (second microdot code 2102) has been detected (step S2303). If the second microdot code 2102 is not detected (step S2303: No), the process is terminated as it is. When the second microdot code 2102 is detected (step S2303: Yes), that is, when the information B is detected, it is determined whether or not the detection flag indicating that the second microdot code 2102 is detected is ON. Determination is made (step S2304).

  If the detection flag is OFF (step S2304: No), the process is terminated as it is. If the detection flag is ON (step S2304: YES), the detection flag is turned OFF (step S2305), a notification sound is output from the speaker 1013 (step S2306), and the process ends.

  In the flowcharts shown in FIGS. 22 and 23, specifically, when the operator operates the detection apparatus 900 and brings the reading unit 910 close to the first microdot code 2101, the first microdot code 2101 is displayed. Detected. Further, when the operator brings the reading unit 910 close to the second microdot code 2102, the second microdot code 2102 is detected. When such a two-step procedure is performed, a predetermined notification sound is output. In the reverse procedure (the first microdot code 2101 is detected after the second microdot code 2102 is detected), the notification sound is not output.

  As described above, according to the second embodiment, the same effects as in the first embodiment can be obtained. In particular, in the second embodiment, since the notification sound is output when the second microdot code 2102 is detected after the first microdot code 2101 is detected, the level of security can be further improved. it can.

  For example, even if there is a fraud in which one of the microdot codes is copied, no notification sound is output, so that such fraud can be found. Even if there is an illegal copy of both the first microdot code 2101 and the second microdot code 2102, if each microdot code 2101 or 2102 is not printed at a predetermined position, the notification sound Is not output, so such fraud can also be detected.

  In the second embodiment, the first micro dot code 2101 and the second micro dot code 2102 are two types, but there are three or more types, and the detection device 900 detects each micro dot code in a predetermined order. In addition, a notification sound may be output. In addition, a predetermined effective period may be provided between detection of the first microdot code 2101 and detection of the second microdot code 2102. That is, the notification sound may be output only when the second microdot code 2102 is detected within a predetermined effective period after the first microdot code 2101 is detected.

  In the second embodiment, the case where a plurality of microdot codes 2101 and 2102 having different information are printed on the printing surface 602 on the transparent film 601 has been described as an example. However, a plurality of types of microdot codes 2101 are described. , 2102 are printed on the second certification sticker 412 (see FIG. 7) and the third certification sticker 413 (see FIG. 8) of the first embodiment. 2102 can be printed. For example, instead of the plurality of microdot codes 603 on the second certification seal 412 of the first embodiment, microdot codes 2101 and 2102 having information A and information B may be printed.

  Further, in the second embodiment, the detection sound is output when the detection device 900 detects the microdot codes 2101 and 2102 in a predetermined order. However, the order is not considered, that is, the order is not determined. For example, when the micro dot codes 2101 and 2102 are detected within a predetermined time, a notification sound may be output.
