Description

  The present invention relates to a gaming machine.

  A slot machine, which is a type of gaming machine, is provided with a main control device that performs lottery drawing of the roles and rotational drive control of each reel in the reel device (design display device). More specifically, the main control device is connected with a inserted medal detection sensor for detecting a inserted medal, a start lever as a start operation means, and a stop switch as a stop operation means. Then, it determines the insertion of medals from the medal detection signal from the inserted medal detection sensor, and starts rotation of each reel by inputting a start detection signal from the start lever in a state where it is determined that a predetermined number of medals have been inserted. Let At this time, the main control device also performs a lottery of the winning combination. Further, the rotation of each reel is stopped by inputting a stop detection signal from the stop switch. When the stop symbol after the stop is a winning symbol or a combination of winning symbols corresponding to the winning combination, a privilege such as a medal payout is given to the player.

  In the slot machine, the gaming state is shifted to a special gaming state such as a big bonus game that is more advantageous than the normal gaming state as one of the benefits. The transition to the special game state is performed when a combination of transition trigger symbols is established as the stop symbol in a state where the information of the transition winning combination is stored in the RAM as the information storage means provided in the main control device. . In this case, when the information on the winning combination for the transition to the big bonus game or the like is stored in the RAM, the stored information on the winning combination for the transition is basically retained until the combination of the transition trigger symbols is established (for example, , See Patent Document 1).

  Further, game state information indicating that the game state is the special game state is also stored in the RAM, and the main control device controls the game based on the stored game state information. The gaming state information is stored and held in the RAM until the special gaming state is completed.

  In the above configuration, for example, an operation of connecting a signal output device to the main control device and outputting the above-described medal detection signal, start detection signal, and stop detection signal from the signal output device is assumed. That is, the signal lines from the inserted medal detection sensor, the start lever, and the stop switch are disconnected from the main control device, and instead, the signal lines from the signal output device are connected to the main control device. Then, each signal is output from the signal output device to the main control device. In this case, the game can be repeatedly performed without actually inserting medals or operating the start lever or the like. Then, such an action is performed when the game hall is closed, and the state of winning the special game state at the time of opening the store or the special game state by storing the information on the winning combination and the game state information in the RAM. There is a risk that the game will be played from the state of transition to.

The above problem is not limited to the slot machine, but also applies to other gaming machines that variably display a plurality of symbols and then stop the variable display of symbols based on the player's operation.

The key cylinder 20 is integrated with a locking device, and is configured such that the locked state is released by a predetermined key operation on the key cylinder 20. Therefore, an outline of the lock mechanism including the locking device will be described.

  On the right end side of the front door 12, that is, on the opposite side of the opening / closing axis of the front door 12, a locking device is provided on the back surface. The locking device extends vertically and is fixed to the front door 12, a key cylinder 20 provided so as to extend from the upper part of the base frame to the front of the front door 12, and moves vertically with respect to the base frame. It is provided with a long interlocking rod 21 assembled as possible. And only the key cylinder 20 is provided in the state which protruded ahead of the front door 12 among the locking devices. The position where the key cylinder 20 is provided is the thin upper portion of the front door 12, and as a result, a versatile key cylinder 20 having a short overall length can be employed. In the present embodiment, Omlock (trade name) having a high function of preventing unauthorized unlocking is used as the key cylinder 20. The interlocking rod 21 is moved downward by operating the key inserted into the key cylinder 20 clockwise. The interlocking saddle 21 is provided with a pair of upper and lower saddle fittings 22 having a bowl shape. When the front door 12 is closed with respect to the casing 11, the saddle fitting 22 is supported on the casing 11 side. Is locked. In addition, the urging member 22 is provided with an urging member such as a coil spring for urging to the side maintaining the locked state. When the key is operated clockwise with respect to the key cylinder 20, the interlocking rod 21 moves downward, and the saddle fitting 22 is moved against the biasing force of the biasing member. The locked state with the support fitting 23 is released, and the locked state of the front door 12 with respect to the housing 11 is released.

  A game panel 30 for notifying the player of the game state is provided above the center of the front door 12. In the game panel 30, three vertically long display windows 31L, 31M, 31R are formed side by side. The display windows 31L, 31M, 31R are made of a transparent or translucent material, and the inside of the slot machine 10 is visible through the display windows 31L, 31M, 31R. The display windows 31L, 31M, and 31R may be combined into a single display window.

  As shown in FIG. 3, the inside of the housing 11 is vertically divided into two by a partition plate 40, and a reel unit 41 constituting variable display means is attached to the upper portion of the partition plate 40. The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R each formed in a cylindrical shape (annular shape). The reels 42L, 42M, and 42R may be configured as at least an endless belt, and are not limited to a cylindrical shape (annular shape). Each of the reels 42L, 42M, and 42R is rotatably supported so that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, and 42R are arranged on the same axis extending in the substantially horizontal direction, and the reels 42L, 42M, and 42R correspond to the display windows 31L, 31M, and 31R on a one-to-one basis. . Accordingly, a part of the surface of each reel 42L, 42M, 42R is visible through the corresponding display windows 31L, 31M, 31R. Further, when the reels 42L, 42M, and 42R are rotated forward, the surfaces of the reels 42L, 42M, and 42R are projected as if moving from top to bottom through the display windows 31L, 31M, and 31R.

  Each of the reels 42L, 42M, and 42R is coupled to the stepping motors 61L, 61M, and 61R, and each of the reels 42L, 42M, and 42R is individually, that is, independently, driven by the stepping motors 61L, 61M, and 61R. Thus, it can be rotationally driven. Since these reels 42L, 42M, and 42R have the same configuration, here, the left reel 42L will be described as an example with reference to FIG. FIG. 6 is an assembled perspective view of the left reel 42L.

  The left reel 42L includes a cylindrical skeleton member 50 that forms a cylindrical cage, and a belt-like belt wound endlessly on the outer peripheral surface thereof. And it is affixed on the cylindrical skeleton member 50 through a pair of seal parts formed along the both sides of the long side of the belt so as to maintain the wound state. A large number of symbols as identification information are printed at equal intervals on the outer peripheral surface of the belt. A boss 51 is formed at the center of the cylindrical skeleton member 50, and is attached to the drive shaft of the left reel stepping motor 61L via a disc-shaped boss reinforcing plate 52. Accordingly, when the drive shaft of the left reel stepping motor 61L is rotated, the cylindrical skeleton member 50 is rotated around the drive shaft so that the left reel 42L circulates along the annular reel surface. It has become.

  The left reel stepping motor 61L is fixed to the side surface of the motor plate 53 arranged in an upright state in the reel unit 41 (FIG. 3) with screws 54. The motor plate 53 is provided with a reel index sensor (rotational position detection sensor) 55 in which a light emitting element 55a and a light receiving element 55b are held at a predetermined interval. On the other hand, the base end portion 56b of the sensor cut bun 56 extending in the radial direction is fixed to the boss reinforcing plate 52 integrated with the left reel 42L by a screw 57. The front end portion 56a of the sensor cut bun 56 is bent at a substantially right angle and is positioned so as to pass between both elements 55a and 55b of the reel index sensor 55. Each time the left reel 42L makes one rotation, the reel index sensor 55 detects the passage of the front end portion 56a of the sensor cut bun 56, and a detection signal is output to the main controller 131 described later each time the detection is made. Therefore, main controller 131 can confirm and correct the angular position of left reel 42L for each rotation based on this detection signal.

  The stepping motor 61L is set to rotate once by giving, for example, a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter), and the rotation position of the stepping motor 61L, that is, left The rotational position of the reel 42L is controlled.

  On each belt of each of the reels 42L, 42M, and 42R, a plurality of, specifically, 21 symbols are drawn in the long side direction (circumferential direction). Therefore, 24 pulses (= 504 pulses ÷ 21 symbols) are required to switch from one symbol to the next symbol at a predetermined position. Based on the number of pulses from when the detection signal of the reel index sensor 55 is output, it is recognized which symbols are visible from the display windows 31L, 31M, and 31R, and arbitrary symbols are displayed on the display window. Control to make it visible from 31L, 31M, 31R can be performed.

  Of the symbols attached to the reels 42L, 42M, and 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, and 31R is mainly determined by the vertical lengths of the display windows 31L, 31M, and 31R. Is limited to a predetermined number. In this embodiment, three reels are provided. For this reason, when all the reels 42L, 42M, and 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

  Here, the symbols attached to the reels 42L, 42M, and 42R will be described. FIG. 7 shows a symbol arrangement drawn on the belt wound around each of the left reel 42L, the middle reel 42M, and the right reel 42R. As shown in the figure, each of the reels 42L, 42M, and 42R is provided with 21 symbols in a row. In addition, numbers 0 to 20 are assigned to the reels 42L, 42M, and 42R, and these numbers are used for the main controller 131 to recognize the symbols that are visible from the display window. It is a number and is not actually attached to the reels 42L, 42M, 42R. However, in the following description, the number is used for explanation.

  The symbols include “Replay” symbol (for example, left belt 20th), “Bell” symbol (for example, left belt 19th), “Youth” symbol (for example, left belt 18th), “7” symbol (for example, (Left belt 17th), “Cherry” design (eg, left belt 13th), “Chance” design (eg, left belt 12th), “Watermelon” design (eg, left belt 9th), “Reach” design ( For example, there are nine types: the 6th left belt) and the “Lucky” symbol (for example, 1st left belt). As shown in FIG. 7, the number of various symbols and the arrangement order are completely different in the belt wound around each reel 42L, 42M, 42R.

  Each reel 42L, 42M, 42R of the reel unit 41 is an example of variable display means for variably displaying identification information, and constitutes a main display unit. However, the variable display means may have a configuration other than this as long as the symbol is variably displayed in the circumferential direction. For example, other mechanical reel configurations such as a type in which the belt is rotated instead of rotating may be used. In addition to the mechanical reel configuration, an electric display such as a liquid crystal display or a dot matrix display may be used. A device for variably displaying the identification information may be provided, and in this case, it is possible to give abundant variations in the display form.

  A total of five combination lines are attached to the game panel 30 such that three display windows 31L, 31M, and 31R are connected to each other and three in parallel in the horizontal direction and two in diagonal directions. Of course, the maximum number of combined lines may be 6 or more, or less than 5, and the maximum number of combined lines may be changed according to a predetermined condition. Corresponding to these combination lines, effective line display sections 32, 33, and 34 are provided on the left side when viewed from the front of the display windows 31L, 31M, and 31R. The first effective line display unit 32 is notified by lighting or the like when the central horizontal line (middle line) of the combination lines is activated. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second effective line display unit 33 is displayed and notified by lighting or the like. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (downward right line and upward right line) of the combination lines is activated. And when the combination line is activated, that is, when the symbol is stopped in a predetermined combination on the effective line, a winning is made, and a predetermined number of medals is paid out or a bonus game such as a BB game which is a special game state is awarded. Migration processing etc. are executed.

  FIG. 8 shows a combination of symbols for winning and the number of medals to be paid out when winning.

  Small prizes for which medals are paid out include a watermelon prize, a bell prize, and a cherry prize. When stopped alongside the “Watermelon” symbol, “Watermelon” symbol, and “Watermelon” symbol from the left on the active line, 15 medals are paid out as a watermelon prize, “Bell” symbol from the left, “Bell” on the active line In the case of stopping alongside the symbol and the “bell” symbol, eleven medals are paid out as a bell prize. When the “cherry” symbol on the left reel 42L stops on the active line, two medals are paid out as a cherry prize. That is, in the case of a cherry winning, any symbol that stops on the active line of the middle reel 42M and the right reel 42R may be any symbol. Therefore, when the “cherry” symbol stops at the position where the plurality of effective lines of the left reel 42L overlap (specifically, the upper stage or the lower stage), a cherry winning is established on each active line, and the overlapping effective The medal is paid out by multiplying the number of lines. As a result, in this embodiment, four medals are paid out.

  Further, there is a BB winning as a state transition winning in which the gaming state shifts. When the “7” symbol, “7” symbol, and “7” symbol are stopped from the left on the active line, the game state shifts to the BB game where the gaming state is the special gaming state as a BB winning. However, even if the “7” symbol stops along the left, middle and right on the active line, no medal is paid out. That is, when the combination of the “7” symbols is established on the active line, only the BB game is entered. In other words, it can be said that the “7” symbol is a state transition symbol for shifting the gaming state to the BB game.

  Furthermore, when the “replay” symbol, “replay” symbol, and “replay” symbol are stopped from the left on the active line, a re-game win is awarded. When the re-game winning is established, the medal payout and the state transition are not performed, but the player can play the next game without reducing the medals owned and without inserting medals.

  In addition, only when the gaming state is an RB game, which will be described later, when stopped alongside the “Replay” symbol, “Replay” symbol, “Chance” symbol from the left on the active line, and from the left on the active line When the “replay” symbol, “replay” symbol, and “lucky” symbol are stopped alongside, 15 medals are paid out as a JAC prize.

  In other cases, that is, when the “cherry” symbol of the left reel 42L does not stop on the active line and the combination of the symbols described above does not stop on the active line, the medal payout, the transition of the gaming state, etc. Not done at all. That is, the “chance” symbol and “lucky” symbol of the left reel 42L, the “cherry” symbol of the middle reel 42M and the right reel 42R, the “young” symbol and the “reach” symbol of each reel 42L, 42M, 42R Not involved at all. In other words, it can be said that each of the symbols is a no-benefits symbol unrelated to the privilege given to the player. As described above, each of the reels 42L, 42M, and 42R is provided with a bonus symbol related to winning such as a “bell” symbol and a non-privileged symbol irrelevant to winning such as a “young” symbol, for example. In the following, a combination of symbols corresponding to each prize is also referred to as a combination of winning symbols. For example, the BB symbol combination is a symbol BB winning combination, that is, a combination of “7” symbol, “7” symbol, and “7” symbol.

  On the lower left side of the game panel 30, a start lever 71 is provided that is operated to start rotation of the reels 42L, 42M, and 42R all at once (not necessarily simultaneously). The start lever 71 is a lever that is pushed by the hand when the player starts the game, and automatically returns to the original position after the hand is released. When the start lever 71 is operated while a medal is inserted, the reels 42L, 42M, and 42R start to rotate all at once.

  On the right side of the start lever 71, button-like stop switches 72, 73, 74 that are operated to individually stop the rotating reels 42L, 42M, 42R are provided. Each of the stop switches 72, 73, 74 is arranged directly below the display windows 31L, 31M, 31R corresponding to the reels 42L, 42M, 42R to be stopped. That is, when the left stop switch 72 is operated, the rotation of the left reel 42L is stopped. When the middle stop switch 73 is operated, the rotation of the middle reel 42M is stopped and the right stop switch 74 is operated. In this case, the rotation of the right reel 42R is stopped. Each of the stop switches 72, 73, 74 can be stopped when a predetermined time elapses after the left reel 42L starts rotating, and is stopped by lighting a lamp (not shown) during such a state. It is notified that the operation is possible, and is turned off when the rotation stops.

  On the lower right side of the display windows 31L, 31M, 31R, there is provided a medal slot 75 for inserting a medal as an investment value. The medals inserted from the medal insertion slot 75 are guided to either the storage passage 81 or the discharge passage 82 by the selector 84 as passage switching means provided on the back surface of the front door 12. That is, the selector 84 is provided with a medal path switching solenoid 83, which is set to the discharge path 82 side when the medal path switching solenoid 83 is not excited, and switched to the storage path 81 side when excited. The medal guided to the storage passage 81 is guided to the hopper device 91 housed in the housing 11. The medal guided to the storage passage 81 is detected by the inserted medal detection sensor 84b described later. On the other hand, the medal guided to the discharge passage 82 is guided to the medal tray 18 from the medal discharge port 17 provided in the lower front portion of the front door 12 and returned to the player.

  A hopper device 91 as a payout means for giving a medal to a player is composed of a storage tank 92 for storing the medal and a payout device 93 for paying out the medal to the player. The payout device 93 rotates a medal payout rotating plate (not shown) to discharge the medal to the opening 94 provided in the central right part of the discharge passage 82 and to the medal tray 18 through the discharge passage 82. To come out. Further, a reserve tank 95 is provided on the right side of the hopper device 91 in order to avoid storing a predetermined amount or more of medals in the storage tank 92. A guide plate 96 for discharging medals from the storage tank 92 to the reserve tank 95 is provided inside the storage tank 92 of the hopper device 91. Therefore, when medals are stored more than the height at which the guide plate 96 is provided, the medals are stored in the reserve tank 95.

  A button-like return switch 76 is provided below the medal slot 75. The return switch 76 is a switch that is pressed when a medal inserted into the medal slot 75 is jammed in the selector 84. When this switch is pressed, the selector 84 is mechanically operated to operate the selector 84. The medals packed in 84 are returned from the medal discharge port 17.

  On the lower left side of the display windows 31L, 31M, 31R, there is provided a button-like first credit insertion switch 77 for inserting three virtual medals credited as investment values at a time. Further, on the left side of the first credit insertion switch 77, a second credit insertion switch 78 and a third credit insertion switch 79 are provided as button switches smaller than the switch 77. The second credit insertion switch 78 is for inserting two credited virtual medals at a time, and the third credit insertion switch 79 is for inserting one virtual medal.

  The first credit insertion switch 77 has a built-in lamp as a light emitting member (not shown) to urge that the maximum number of medals that can be inserted per game (three) has not been reached. The lamp is turned on when the switch operation of the first credit insertion switch 77 is valid and prompts the operation of the switch 77. However, when there is no credited virtual medal or three medals have already been inserted. It is turned off under the circumstances. Here, instead of the above-described lighting, the player may make it easier to understand the prompt for medal insertion by blinking.

  A button-like settlement switch 80 is provided on the left side of the start lever 71. That is, the slot machine 10 has a credit function for storing and storing surplus inserted medals up to a predetermined maximum value (for 50 medals) and winning medals as virtual medals. The virtual medal is paid out as an actual medal when the settlement switch 80 is pressed while stored and stored. In this case, if paying attention to the function of paying out a credited virtual medal as an actual medal, it can be said that the checkout switch 80 constitutes a checkout operation means for actually paying out the stored game value.

  It should be noted that the surplus inserted medals up to a predetermined maximum value (for example, 50 medals) and the “credit mode” set to store and memorize the winning medals as virtual medals, the surplus inserted medals, In the case of a slot machine that can be switched to “direct mode” set so that the winning medal at the time of winning is paid out as an actual medal, the settlement switch 80 has a function as a changeover switch for mode switching. May be added. In this case, the settlement switch (changeover switch) 80 is turned on when pressed once, turned off when pressed again, and switched on / off every time a pressing operation is performed. When the settlement switch 80 is on, the credit mode is selected. When the settlement switch 80 is off, the direct mode is selected. If there are virtual medals when the credit mode is switched to the direct mode, the virtual medals corresponding to the virtual medals are paid out as real medals. Thereby, the player can execute the game in a format according to his / her preference by switching between the credit mode and the direct mode. The settlement switch 80 constitutes a switching operation means for switching the input value and game value handling formats.

  Below the display windows 31L, 31M, and 31R of the game panel 30, a credit display unit 35 that displays the number of virtual medals stored and stored, and the remaining number of acquired medals that displays the number of remaining medals that can be acquired before the BB game is over. A display unit 36 and an acquired number display unit 37 for displaying the number of medals acquired at the time of winning are provided. Although these display parts 35-37 are comprised by the 7 segment display, it is naturally possible to substitute by a liquid crystal display etc. FIG.

  Here, a procedure for betting medals will be described. If a medal is inserted from the medal slot 75 at the start of the game, a bet is placed.

  That is, when the first medal is inserted into the medal insertion slot 75, the first effective line display section 32 is turned on, and the corresponding middle line becomes the effective line, and the second medal is the medal insertion slot. When the number 75 is inserted, the second effective line display section 33 is turned on, and a total of three combination lines including an upper line and a lower line corresponding to the second effective line display section 33 become effective lines, respectively. When it is inserted into the insertion port 75, the third effective line display unit 34 is further turned on, and a total of five combination lines including a pair of diagonal lines corresponding thereto become effective lines.

  When four or more medals are inserted into the medal slot 75, the surplus medals exceeding three are stored inside the slot machine if the number of virtual medals stored and stored at that time is less than 50. At the same time, the number of virtual medals on the credit display unit 35 is added and displayed. On the other hand, when the number of virtual medals is 50 or reaches 50, the selector 84 switches from the storage passage 81 to the discharge passage 82, and the surplus medals are returned from the medal discharge port 17 to the medal tray 18. Is done.

  Further, when the stored number is displayed on the credit display unit 35, a virtual medal is inserted even when any of the first to third credit insertion switches 77 to 79 is pressed, and a bet is made. .

  When the third credit insertion switch 79 is pressed, the numerical value displayed on the credit display unit 35 is decremented by one as a virtual medal is inserted, and the first effective line display unit 32 is turned on. The middle line becomes the active line. When the second credit insertion switch 78 is pressed, two numerical values displayed on the credit display unit 35 as two virtual medals are inserted are subtracted, and the first valid line display unit 32 and the second The effective line display unit 33 is turned on, and a total of three combination lines become effective lines. When the first credit insertion switch 77 is pressed, three numerical values displayed on the credit display unit 35 are subtracted as three virtual medals are inserted, and all the effective line display units 32 to 34 are displayed. Lights up and a total of five combination lines become effective lines.

  In addition, when the virtual medal to be inserted when any of the first to third credit insertion switches 77 to 79 is pressed is not stored, for example, when the display of the credit display unit 35 is 2, the first credit For example, when the insertion switch 77 is pressed, all the numerical values in the credit display unit 35 are subtracted to 0, and a bet is placed for the virtual medal that can be inserted.

  Such a configuration for power failure is also provided for the RAM 153. That is, the RAM 153 is provided with a backup area 153a in addition to a memory for temporarily storing various data. The backup area 153a stores the stack pointer value and various data when the power is shut down due to the occurrence of a power failure or the like (including power shut down by operating the power switch 122; the same applies hereinafter). When the power failure is resolved (including power-on by operating the power switch 122. The same applies hereinafter), the state of the slot machine 10 can be restored to the state before power-off based on the information in the backup area 153a. It is like that. Writing to the backup area 153a is executed when the power is shut off by the power failure process (see FIG. 13), and the restoration of each value written to the backup area 153a is executed in the main process (see FIG. 14) when the power is turned on.

  In addition to the power supply device 161, the CPU 151 includes a start lever 71, stop switches 72 to 74, credit insertion switches 77 to 79, a settlement switch 80, a selector 84, a reset switch 123, a reel unit 41, a hopper device 91, and a setting key. A setting key detection sensor 124a that detects that a setting key is inserted into the insertion hole 124 and is turned on, and an external concentration terminal board 171 that can output information to a hall management device that manages the entire game hall are connected. Yes.

  In this case, the start lever 71, the stop switches 72 to 74, the credit insertion switches 77 to 79, the settlement switch 80, and the selector 84 are connected via a relay board 165 (see FIGS. 3 and 4) provided on the front door 12. Connected. These start levers 71 and the like are disposed on the front door 12, and wiring can be easily routed through the relay substrate 165. The reel unit 41 and the like may be connected via a dedicated relay board.

  The selector 84, the reel unit 41, and the hopper device 91 can input and output signals. Specifically, regarding the selector 84, a detection signal from an inserted medal detection sensor that detects a medal inserted from the medal insertion slot 75 is input and an excitation signal is output to the medal path switching solenoid 83. With respect to the reel unit 41, a detection signal from a reel index sensor 55 that individually detects the rotation position (origin position) of each reel 42 is input, and each stepping motor 61 for rotating each reel 42L, 42M, 42R. A drive signal is output to (61L, 61M, 61R). As for the hopper device 91, a detection signal from a payout detection sensor that detects medals paid out from the hopper device 91 is input, and a drive signal is output to a payout device 93 that executes payout of medals.

  The display control device 111 is a control device for driving the upper lamp 13, the speaker 14, and the auxiliary display unit 15, and includes a substrate in which a CPU, a ROM, a RAM, and the like for driving these are integrated. Then, after receiving a signal from the main control device 131, the display control device 111 independently drives and controls the upper lamp 13, the speaker 14, and the auxiliary display unit 15. Although not shown in the figure, each of the active line display units 32, 33, 34, the credit display unit 35, the remaining acquired number display unit 36, and the acquired number display unit 37 is also connected to the CPU 151 of the main control device 131. The display is controlled by the CPU 151.

  Here, in this embodiment, a characteristic configuration is provided with respect to power supply to the RAM 153. Therefore, this characteristic configuration and the configuration related thereto will be described based on the block circuit diagram of FIG.

  The start lever 71 and the stop switches 72 to 74 are provided as part of the start operation device 181 and the stop operation device 182, respectively. Specifically, each of the devices 181 and 182 is provided with a start operation board 181a on the start operation apparatus 181. A start lever 71 is connected to the start operation board 181a. In this case, the signal line LN1 that connects the start lever 71 and the start operation board 181a is provided in a non-detachable state. That is, the connection portion of the signal line LN1 to the start lever 71 and the start operation board 181a is fixed by soldering or the like without passing through the connector. The operation of the start lever 71 is detected by the start operation board 181a, and a start detection signal is output to the relay board 165 via the signal line LN2 connecting the start operation board 181a and the relay board 165. The signal line LN2 is detachably attached via connectors CN1 and CN2.

  The stop operation device 182 is provided with a stop operation substrate 182a, and stop switches 72 to 74 are connected to the stop operation substrate 182a. In this case, the signal line LN3 connecting the stop switches 72 to 74 and the stop operation board 182a is provided in a non-detachable state, like the start operation device 181. Then, the operation of the stop switches 72 to 74 is detected by the stop operation board 182a, and a stop detection signal is output to the relay board 165 via the signal line LN4 that connects the stop operation board 182a and the relay board 165. . The signal line LN4 is detachably attached via connectors CN3 and CN4.

  Similar to the start operation device 181 and the stop operation device 182, the selector 84 is provided with a selector substrate 84a. An inserted medal detection sensor 84b that detects a medal inserted from the medal slot 75 is connected to the selector board 84a. In this case, the signal line LN5 connecting the inserted medal detection sensor 84b and the selector substrate 84a is provided in a non-detachable state, like the start operating device 181 and the stop operating device 182. Then, a signal from the inserted medal detection sensor 84b is detected by the selector board 84a, and a medal detection signal is output to the relay board 165 via the signal line LN6 connecting the selector board 84a and the relay board 165. The The signal line LN6 is detachably attached via connectors CN5 and CN6. As described above, a drive signal is output from the main controller 131 to the selector 84. However, in the description based on FIG.

  The relay board 165 is connected to the main control board 131 a of the main control device 131 via the harness H. Various signals output from the start operation board 181a, the stop operation board 182a, and the selector board 84a are input to the main control board 131a via each signal line constituting the harness H. In this case, the harness H is detachably attached via the connectors CN7 and CN8. Since the relay board 165 is connected to a plurality of signal lines in addition to the signal lines from the boards 181a, 182a, and 84a, the harness H is provided with signal lines corresponding thereto. .

  From the power supply unit 161a of the power supply device 161, power is supplied not only to the main control board 131a but also to the starting operation board 181a. That is, the power supply unit 161a is provided with the power supply line ELN1 extending toward the main control board 131a and the power supply line ELN2 extending toward the start operation board 181a. The CPU 151 is operated by power supplied from the power line ELN1, and various processes described later are executed. However, the supply power from the power supply line ELN1 is not supplied to the RAM 153.

  The power supplied to the start operation board 181a by the power line ELN2 is supplied to the RAM 153 via the relay board 165. Specifically, a power supply line ELN3 is provided between the connectors CN1 and CN2 of the signal line LN2 that connects the start operation board 181a and the relay board 165. The harness H that connects the relay board 165 and the main control board 131a includes a power line. The power supplied from the power line included in the harness H is supplied to a VBB terminal that is a backup power supply terminal provided in the CPU 151. Therefore, power from the power supply line ELN2 is supplied to the RAM 153, and various data are stored and held in the RAM 153 by the supplied power.

  A backup capacitor 181b is provided on the starting operation board 181a. The backup capacitor 181b is supplied with power from the power supply line ELN2, and is stored in the backup capacitor 181b when the power of the slot machine 10 is ON. The backup capacitor 181b is connected to the power supply line ELN3 described above. Therefore, when the power of the slot machine 10 is OFF, the backup capacitor 181 b is discharged, and the backup power is supplied to the RAM 153. Therefore, even if the power of the slot machine 10 is turned off, the data stored in the RAM 153 is held without being erased while the power is supplied from the backup capacitor 181b. Incidentally, the capacity of the backup capacitor 181b is ensured to be relatively large, and the information stored in the RAM 153 before the power is shut off is retained within a predetermined period (for example, 1 day or 2 days).

  With the above configuration, a signal output device that outputs a start detection signal, a stop detection signal, and a medal detection signal is connected to the main control board 131a, and a BB prize is generated by outputting each signal. It is possible to suppress cheating.

  Explaining the fraudulent act, as will be described later, in this slot machine 10, a predetermined number of medals are inserted, and then the start lever 71 is operated, so that the winning combination is lottery and each reel 42L. , 42M, 42R starts to rotate. Then, when the stop switches 72 to 74 are operated, the rotations of the reels 42L, 42M, and 42R are stopped. Therefore, by replacing the signal output device with the main control board 131a, it is possible to repeatedly play a game without actually inserting medals or operating the start lever 71 and the stop switches 72 to 74. In this case, a winning combination of BB will occur.

  For example, when the cheating is performed after the game hall is closed, the power to the slot machine 10 is turned off in a state where the winning combination of the BB is generated. Since the winning information of the BB role (BB winning flag to be described later) is basically stored in the RAM 153 until a BB winning occurs, the slot machine 10 in which the illegal act was performed at the time of opening the store is in a state where the BB role is won. The game will be started. When a BB prize is generated, a large amount of medals are paid out, which is a great disadvantage for a game hall or the like. Note that whether or not the winning combination of BB has occurred can be determined by the manner of the stop symbol when each reel 42L, 42M, 42R stops. In addition, for example, when the fraudulent act is performed while the game hall is in operation, an act of stopping the combination of symbols that become a BB prize after winning the BB role is performed.

  Furthermore, it is assumed that the above action is intentionally performed in the game hall, not as an illegal act. In other words, by causing the slot machine 10 to win the BB role using the same device as the signal output device when the store is closed, the game of the slot machine 10 starts with the BB role selected as described above. Is done. In this case, the player's attention to the game hole is increased. However, this is unfavorable because it will unjustly irritate.

  Such a fraudulent act (an act of unjustly gambling if the game hall is intentionally performed) removes the harness H that connects the relay board 165 and the main control board 131a, and the connector CN8 of the harness H is connected. This is performed by connecting a harness extending from the signal output device to the connector CN9 on the main control board 131a side. In addition to this, a signal line LN2 that connects the start operation board 181a and the relay board 165, a signal line LN4 that connects the stop operation board 182a and the relay board 165, and a signal line that connects the selector board 84a and the relay board 165. This is done by removing LN6 and connecting signal lines extending from the signal output device to connectors CN10, CN11, CN12 on the relay board 165 side to which connectors CN2, CN4, CN6 of these signal lines LN2, LN4, LN6 were connected. .

  On the other hand, as described above, the power to the RAM 153 is supplied via the start operation board 181a. That is, power is supplied to the RAM 153 via the power supply line ELN3 and the harness H provided between the connectors CN1 and CN2 that connect the signal line LN2. Therefore, even if the harness H and the signal line LN2 are removed and the signal output device is connected, power is not supplied to the RAM 153. Since the RAM 153 does not function, it becomes impossible for the CPU 151 to perform various processes to be described later, and the above-mentioned fraudulent act cannot be performed. Even if power is supplied to the RAM 153 from the signal output device, the power to the RAM 153 is cut off when the signal output device is disconnected and the connector LN2 and the harness H are connected. Therefore, the winning information of the BB combination stored in the RAM 153 is erased, and the above-mentioned fraudulent act cannot be performed.

  It is also assumed that the signal output device is replaced with respect to the main control board 131a on the terminal side of the signal line LN2. That is, it is assumed that the signal line LN1 that connects the start lever 71 and the start operation board 181a is removed and the signal output device is connected to the start operation board 181a instead. On the other hand, in the present embodiment, the signal line LN1 is fixed to the starting operation board 181a with solder or the like, and is in a state in which it cannot be removed. Therefore, it is impossible (or difficult) to replace the main control board 131a with the signal output device on the terminal side of the signal line LN2, and the signal output device on the terminal side can be changed. The act of trying to replace can be suppressed.

  Next, each control process executed by the CPU 151 in the main controller 131 will be described with reference to the flowcharts of FIGS. The processing of the CPU 151 is broadly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in a cycle of 1.49 msec in the present embodiment), and an NMI terminal (non-maskable terminal). For convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  FIG. 11 is a flowchart showing an example of the NMI interrupt process. When the power is shut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 161b of the power supply device 161 generates a power failure signal and outputs it to the main controller 131. In the main controller 131 that receives the power failure signal via the NMI terminal, NMI interrupt processing is executed.

  In the NMI interrupt processing, first, in step S101, the data of the used register provided in the CPU 151 is saved in the backup area 153a provided in the RAM 153. Subsequently, in step S102, the power failure flag is set in a power failure flag storage area provided in the RAM 153. Thereafter, the data saved in the backup area 153a of the RAM 153 in step S103 is restored to the use register of the CPU 151 again. With this return processing, the NMI interrupt processing ends. If the power failure flag can be set without destroying the data in the used registers of the CPU 151, the saving and restoring processing to the backup area 153a can be omitted.

  FIG. 12 is a flowchart of a timer interrupt process periodically executed by the main control device 131. A timer interrupt is generated by the CPU 151 of the main control device 131 every 1.49 msec, for example.

  First, in the register saving process shown in step S201, the values of all registers in the CPU 151 used in the normal process described later are saved in the backup area 153a of the RAM 153. In step S202, it is confirmed whether or not a power failure flag is set. If the power failure flag is set, the process proceeds to step S203, and a power failure process is executed.

  Here, the power failure process will be described with reference to FIG. Since the power failure process is performed immediately after the register saving process in the timer interrupt process, other interrupt processes can be executed without interruption. Therefore, the process at the time of power failure is not executed by interrupting each process, for example, during the output process of various commands, or during the process of reading the switch state (ON / OFF), and is executed at such timing. It is no longer necessary to create a power failure processing program that also takes into account This simplifies the processing program for power failure processing and reduces the program capacity. This also applies to a processing program for power recovery processing described later.

  In step S301, it is determined whether command output has been completed. If the output is not finished, this process is finished, the process returns to the timer interrupt process, and the command output is finished. In this way, it is determined whether or not command output is completed at the initial stage of power failure processing, and when output is incomplete, priority is given to output processing, and power failure processing is executed after unit command output processing is completed. By doing so, it is not necessary to construct a power failure processing program that takes into account that the power failure processing is executed during the output of the command. As a result, the power failure processing program can be simplified and the ROM 152 can be reduced in capacity.

  If step S301 is YES, that is, if the command output has been completed, the process proceeds to step S302, and the value of the stack pointer of the CPU 151 is stored in the backup area 153a in the RAM 153. Thereafter, in step S303, a RAM determination value, which will be described later, is cleared as a stop process, and the output state of the output port in the input / output port is cleared, and all actuators (not shown) are turned off. In step S304, a RAM determination value is calculated and stored in the backup area 153a. The RAM determination value is specifically a 2's complement of the checksum at the work area address of the RAM 153. By saving the RAM determination value in the backup area 153a, the checksum of the RAM 153 becomes zero. By setting the checksum of the RAM 153 to 0, subsequent RAM access is prohibited in step S305. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed. In consideration of, for example, the case where the power failure flag is set erroneously due to noise or the like, it is confirmed whether or not a power failure signal is output until the infinite loop is entered. If the power failure signal is not output, the power failure state is restored, so that writing to the RAM 153 is permitted, the power failure flag is reset, and the process returns to the timer interrupt process. If the power outage signal is continuously output, the infinite loop is entered. Incidentally, although a detailed description is omitted, it is confirmed whether or not a power failure signal is output even under an infinite loop.

  The power supply unit 161a of the power supply device 161 holds the output of the stabilization voltage (5 volts) used as the drive voltage for the control system for a time sufficient to execute the above-described NMI interrupt processing and power failure processing. It is comprised so that. In the present embodiment, the drive voltage is continuously output for 30 msec.

  Returning to the description of the timer interrupt process, if the power failure flag is not set in step S202, various processes after step S204 are performed.

  That is, in step S204, a watchdog timer clearing process for initializing the value of the watchdog timer for monitoring the occurrence of malfunction is performed. In step S205, an interrupt end declaration process is performed to enable the next timer interrupt to be set for the CPU 151 itself. In step S206, in order to rotate the reels 42L, 42M, and 42R, a stepping motor control process for driving the stepping motors 61L to 61R, which are the respective rotary drive motors, is performed. In step S207, the state of various switches connected to the input / output port is read, and sensor monitoring processing is performed to monitor whether the read result is normal. In step S208, timer calculation processing for subtracting the value of each counter or timer is performed. In step S209, a counter process for outputting the bet number of medals and the result of counting the number of payouts to the external concentration terminal board 171 is performed.

  In step S210, command output processing for outputting various commands to the display control device 111 is performed. In step S211, segment data setting processing for setting segment data to be displayed on the credit display unit 35, the remaining acquired number display unit 36, and the acquired number display unit 37 is performed. In step S212, segment data set processing in the segment data setting processing is supplied to the display units 35 to 37, and segment data display processing for displaying corresponding numbers, symbols, and the like is performed. In step S213, port output processing for outputting data corresponding to the I / O device from the input / output port is performed. In step S214, the value of each register saved in the backup area 153a in the previous step S201 is restored to the corresponding register in the CPU 151. Thereafter, in step S215, an interrupt permission process for permitting the next timer interrupt is performed, and this series of timer interrupt processes is terminated.

  FIG. 14 is a flowchart showing a main process in the main controller 131 that is executed after the power is turned on. The main process is executed when the power is turned on by recovery from a power failure or by turning on the power switch 122.

  First, in step S401, as initialization processing, the value of the stack pointer is set in the CPU 151, and an interrupt mode that permits interrupt processing is set. And so on.

  When these initialization processes are completed, in step S402, whether or not the setting key is inserted into the setting key insertion hole 124 and is turned ON, more specifically, whether or not the ON signal is input from the setting key detection sensor 124a. Determine. If the setting key has been turned ON, the process proceeds to step S403, and all data stored in the RAM 153 is cleared as a forced RAM clear process. In subsequent step S404, a winning probability setting process is performed.

  Here, the winning probability setting process will be described with reference to FIG. The slot machine 10 is prepared in advance with six stages of winning probabilities from “Setting 1” to “Setting 6”, and the winning probability setting process sets which winning probability is used to execute the internal processing. It is a process to do.

  In step S501, it is determined whether or not the setting key is inserted and the ON operation is performed. If it is ON, the next timer interrupt is permitted in step S502. Thereafter, the current set value is read in step S503, and the current set value is displayed on the credit display unit 35 in step S504. However, in the process immediately after the setting key is inserted and turned ON, the data in the RAM 153 is cleared by the previous forced RAM clear process, so the set value displayed on the credit display unit 35 is “1”. is there.

  In step S505, it is determined whether or not the start lever 71 has been operated. If the start lever 71 has not been operated, setting update processing shown in steps S506 to S507 is performed. In step S506, it is determined whether or not the reset switch 123 has been operated. If the reset switch 123 is not operated, the process directly returns to step S504. If the reset switch 123 is operated, the set value is updated by 1 in step S507, and then the process returns to step S504. That is, in the setting update process, every time the reset switch 123 is operated, the setting value is updated by 1, and the updated setting value is displayed on the credit display unit 35. When the reset switch 123 is operated when the set value is “6”, the set value is updated to “1”.

  If the start lever 71 is operated in step S505, it is determined in step S508 whether the setting key is continuously turned on. If the ON operation of the setting key is continued, the process waits as it is. If the ON operation is ended, the next timer interruption is prohibited in step S509. Thereafter, the set value is stored in step S510, data other than the set value stored in the RAM 153 is cleared in step S511, and this process is terminated.

  Returning to the description of the main process, after performing the winning probability setting process in step S404, a normal process for performing main control relating to the game is executed in step S405.

  On the other hand, when the setting key is not inserted in step S402, power recovery processing shown in step S406 and subsequent steps is performed. The power recovery process is a process for returning the state of the slot machine 10 to the state before the power is shut off. Therefore, in the power recovery process, it is necessary to first check whether the data in the RAM 153 is normal.

  Therefore, in step S406, it is determined whether or not the set value is normal. Specifically, when the set value is any one of 1 to 6, it is determined to be normal, and when it is 0 or 7 or more, it is determined to be abnormal. If the set value is normal, it is confirmed in step S407 whether or not a power failure flag is set. If the power failure flag is set, it is further confirmed in step S408 whether or not the RAM determination value is normal. Specifically, the value of the checksum in the RAM 153 is checked to check whether the value is normal, that is, whether the value of the checksum including the RAM determination value is 0. If the checksum value including the RAM determination value is 0, it is determined that the data in the RAM 153 is normal.

  If it is determined in step S408 that the RAM determination value is normal, the process proceeds to step S409, the stack pointer value stored in the backup area 153a is written to the stack pointer of the CPU 151, and the stack state is set before the power is shut off. Return to the state. Next, in step S <b> 410, a power recovery command that tells execution of power recovery processing is output to the display control device 111. Thereafter, in step S411, the game state is stopped and automatic settlement setting storage processing is performed, and in step S412, various devices such as the start operation device 181 are initialized. After the above processing is completed, the power failure flag is reset in step S413, and the processing returns to the address before the power is shut off. Specifically, the process returns to the timer interrupt process described above, and the watchdog timer clear process (step S204) is executed.

  On the other hand, if any of step S406 to step S408 is NO, that is, the set value is abnormal, the power failure flag that is set when the power is shut off is not set, or the RAM determination value is abnormal, There is a high possibility that the data in the RAM 153 has been destroyed. In such a case, the operation prohibiting process shown in steps S414 to S416 is performed. As the operation prohibition process, first, the next timer interrupt process is prohibited in step S414. In step S415, all the output ports in the input / output port are cleared, so that all actuators connected to the input / output port are turned off. To control. Thereafter, in step S416, an error notification process for notifying the hole manager or the like of the occurrence of an error is performed. This operation prohibition state is maintained until the above-described winning probability setting process is performed.

  Next, normal processing for performing main control related to the game will be described based on the flowchart of FIG.

  First, in step S601, it is determined whether or not a medal is bet. If a medal is bet, it is determined in step S602 whether the start lever 71 has been operated. If both step S601 and step S602 are YES, the lottery process in step S603, the reel control process in step S604, the medal payout process in step S605, and the bonus game process in step S606 are executed in order, and the process returns to step S601. On the other hand, if no medal is bet in step S601 or the start lever 71 is not operated in step S602, the process returns to step S601.

  Next, the lottery process in step S603 will be described based on the flowchart of FIG.

  In step S701, a lottery table for determining success / failure is selected based on the current setting state of the slot machine 10, the number of bets placed, and the like. Here, the setting state of the slot machine 10 is any one of “setting 1” to “setting 6”. When “setting 1”, the lottery table having the lowest BB winning probability is selected, and when “setting 6” is set. The lottery table having the highest BB winning probability is selected. The number of medals to bet is any one of 1 to 3, and a lottery table is selected such that the winning probability of winning combination increases as the number of bets increases. For example, the winning probability of a winning combination when three bets are higher than the winning probability of winning when a single bet is three times. Here, the lottery table will be briefly described. FIG. 18 is a lottery table that is selected when three bets are placed under the normal state of “Setting 1”. In the lottery table, the same number of index values IV as the number of winning combinations is set. That is, under the normal state, five types of winnings of replay, cherry, bell, watermelon, and BB can occur (see FIG. 8), so five index values IV of 1 to 5 are set. Each index value IV is uniquely associated with a winning combination, and a point value PV is set. In each lottery table in the slot machine 10, the point value PV corresponding to the BB combination is set to be larger for the lottery table having a higher set value, and the point value PV is set to be larger as the bet number is larger.

  In step S702, the index value IV is set to 1, and in the subsequent step S703, a determination value DV used for determining whether or not the winning combination is determined is set. In the determination value setting process, a new determination value DV is set by adding a point value PV corresponding to the current index value IV to the current determination value DV. In the first determination value setting process, the random value latched by the random number counter when the start lever 71 is operated is set as the current determination value DV, and this random value is a point corresponding to 1 which is the current index value IV. The value PV is added to obtain a new determination value DV. Here, the random number counter will be briefly described. In the slot machine 10, random numbers from 0 to 65535 are generated using two 8-bit shift registers. Each shift register is updated one by one periodically (for example, every 100 ns), and a value obtained by exchanging the upper and lower bits of each shift register is input to the CPU 151 and the start lever 71 is operated (that is, the start operation device 181). The input value is latched as a random value. This is a device for making the random value used in the initial determination value setting process irregular. For example, a value obtained by randomly replacing the bits of each shift register is latched as a random value. Also good.

  Thereafter, in step S704, it is determined whether or not the combination corresponding to the index value IV is correct. In the winning / no-going determination of the combination, it is determined whether or not the determination value DV exceeds 65535. If the determination value DV exceeds 65535, the winning combination flag corresponding to the index value IV at that time is provided in the RAM 153 in step S705. Set in the corresponding winning flag storage area. Incidentally, when the winning flag is a small role winning flag or a replay winning flag, these winning flags are reset (cleared) at the end of the game in which the corresponding winning flag is set. On the other hand, when the winning flag is the BB winning flag, the BB winning flag is reset (cleared) on the condition that the combination of the BB symbols is established on the active line. That is, the BB winning flag may be valid for a plurality of games. In addition, in the success / failure determination of the winning combination after the next game carrying over the BB winning flag, the determination of whether or not the small combination or replay is made is performed, but the determination of whether or not the BB is related is not performed.

  If the determination value DV does not exceed 65535 in step S704, it means that the combination corresponding to the index value IV is lost. In such a case, 1 is added to the index value IV in step S706, and in the subsequent step S707, it is determined whether or not there is a role corresponding to the index value IV, that is, whether or not there is a role to be determined. Specifically, it is determined whether or not the index value IV added by 1 exceeds the maximum value of the index values IV set in the lottery table. If there is a winning combination to be judged, the process returns to step S703 and the winning judgment is continued. At this time, in step S703, a point value PV corresponding to the current index value IV is added to the determination value DV (that is, the current determination value DV) used to determine whether or not the previous winning combination is a new determination value DV. In step S704, the winning combination determination is performed based on the determination value DV. Incidentally, when the lottery table shown in FIG. 18 is selected, the BB winning probability is about 1/300. On the other hand, the replay and small role winning probabilities are set higher than the BB winning probability, the replay winning probability is about 1 / 7.3, the bell winning probability is about 1 / 7.0, and the cherry and watermelon winning probabilities The probability is 1/128.

  After setting the winning flag in step S705 or if it is determined in step S707 that there is no winning combination, a slip table for setting a reel stop control (stop table) is set in step S708. Perform table setting processing. Here, the slip table is a table in which it is determined how much the reel is slid (rotated) and stopped after the stop switches 72 to 74 are pressed. In other words, the slip table is a symbol that reaches the base point position (on the lower line in this embodiment) when the stop switches 72 to 74 are pressed, and a stop symbol that actually stops at the base point position. This is a stop data group with a defined relationship.

  Since this embodiment has a feature in the data structure related to the sliding table, this point will be described.

  In the slot machine 10, when the stop switches 72 to 74 are operated, when the reaching symbol is stopped as it is, when the corresponding reel is stopped after sliding for one symbol, it is stopped after sliding for two symbols. In this case, five patterns are prepared as a reel stop mode, in the case of stopping after sliding for three symbols, and for stopping after sliding for four symbols. This closely matches the timing at which the player operates the stop switches 72 to 74 and the symbol arrangement (hereinafter referred to as “stop appearance”) that stops in a visible range from each display window 32L, 32M, 32R. It is a device for associating. That is, by stopping the reels 42L, 42M, and 42R until the specified time (190 msec) has elapsed from the timing at which the stop switches 72 to 74 are operated, it is as if the stop outcome has been determined by the player's operation. It is possible to make a player have a good impression. In addition, by making it possible to slide up to 4 symbols, it becomes possible to stop combinations of symbols corresponding to the winning combination in the lottery on the active line as much as possible within the specified time. .

  There are five types of stop data relating to such a stop mode (no slip, one frame slip, two frames slip, three frames slip, four frames slip), five types for the middle reel 42M, and five types for the right reel 42R. is necessary. In this case, if the stop data related to each reel 42L, 42M, 42R is allocated in units of bits, 3 bits of stop data are required for each reel 42L, 42M, 42R, and cannot be stored in one byte.

  In this regard, in the present embodiment, since five types of stop data are required, the compressed data is created assuming that the stop data is collectively a hexadecimal number. That is, the stop data is configured as “(data of the left reel 42L) × 36 + (data of the middle reel 42M) × 6 + (data of the right reel 42R)”. In this case, the maximum number of stop data that can be prepared for each reel 42L, 42M, and 42R is six, and there are 6 × 6 × 6 = 216 combination patterns for the stop data as a whole. The maximum value that can be expressed is 256 or less. As a result, the stop data for all the reels 42L, 42M, and 42R can be stored in one byte even though there are five types of stop data for each reel 42L, 42M, and 42R. Each reel 42L, 42M, 42R has 21 symbols, so one slide table can be composed of 21 bytes, and the storage capacity of the main controller 131 can be reduced. It becomes. Incidentally, in this embodiment, approximately 60 types of 21-byte sliding tables are stored in the ROM 152 in advance.

  Further, in the slot machine 10 that stores each piece of stop data as compressed data, a predetermined decompression process is performed when each piece of stop data is used. Specifically, the compressed data corresponding to the symbol number of the reaching symbol is divided by “36” (= 6 × 6), and the obtained quotient is grasped as stop data of the left reel 42L. Further, the remainder obtained by the division is divided by “6”, and the obtained quotient is grasped as stop data for the middle reel 42M, and the remainder is grasped as stop data for the right reel 42R.

  Through the processing described above, the CPU 151 can grasp the stop data of each reel 42L, 42M, 42R as decompressed data. The stop data for all the reels 42L, 42M, and 42R may be configured so as to be accommodated in one byte. For example, the stop data may be combined into a quintic number to create compressed data. . As a condition for stopping data to fall within 1 byte, a value obtained by multiplying the maximum number that can be prepared as stop data for each reel 42L, 42M, 42R may be 256 or less. Therefore, the maximum number of stop data that can be prepared for each reel 42L, 42M, 42R is not necessarily the same. For example, even when 6 types of stop data can be prepared for the left reel 42L, 8 types for the middle reel 42M, and 4 types of stop data for the right reel 42R, the combination pattern of the entire stop data is 6 × 8 × 4 = 192. Since the maximum value is 256 or less that can be expressed in 1 byte, stop data for all reels 42L, 42M, and 42R can be stored in 1 byte. Incidentally, in such a case, the compressed data is “(data of the right reel 42R) × 48 + (data of the middle reel 42M) × 6 + (data of the left reel 42L)”, and the decompression process corresponds to the symbol number of the reaching symbol. The quotient obtained by dividing the compressed data to be divided by “48” is used as stop data for the right reel 42R, and the quotient obtained by dividing the remainder obtained by dividing by “6” is the stop for the middle reel 42M. The remaining data is grasped as stop data of the left reel 42L.

  FIG. 19 is an example of a sliding table that is set when the watermelon symbol is stopped on the active line. The symbol having the number of slips of 0 is a symbol that actually stops on the lower line. For example, if the left stop switch 72 is pressed while the “bell” symbol which is the seventh symbol of the left reel 42L has reached the lower line, the left reel 42L stops without slipping and becomes the ninth symbol. The “watermelon” symbol stops on the upper line. In addition, a symbol whose number is not zero means that the reel slides by the number of symbols described. For example, when the left stop switch 72 is pressed while the “replay” symbol which is the eighth symbol of the left reel 42L has reached the lower line, the left reel 42L slides by one symbol and becomes the ninth symbol. The “watermelon” symbol stops on the lower line. That is, if a stop switch is pressed when a symbol with a number of non-slip numbers reaches the lower line, the corresponding reel slides until a symbol with a zero slip number reaches the lower line. Stop. Thus, in the sliding table, the number of slips when the stop switches 72 to 74 are pressed at the timing when the symbols attached to the reels 42L, 42M, and 42R reach the lower line is set for each symbol number. Yes. For example, stop data with a left slip number of 2, a middle slip number of 0, and a right slip number of 3 for symbol number 0 is set as 1-byte compressed data. One compressed data is obtained from the compressed data for each symbol number, that is, 21-byte compressed data. The table is configured.

  As shown in FIG. 20, in the slip table setting process, it is first determined in step S801 whether or not the BB winning flag is set. If the BB winning flag is not set, the process proceeds to step S802, and the first winning number uniquely corresponding to the winning flag is set in the winning number storage area of the RAM 153. The winning number is a number used to set the slip table. When the first winning number is set, the winning flag is not set or only one winning flag is set. Means. In the subsequent step S803, a sliding table uniquely determined from the value of the first winning number is set in the sliding table storage area of the RAM 153, and this process ends. At this time, in the slot machine 10, the symbol corresponding to the winning flag of the middle reel 42M and the right reel 42R is medium so that the symbol corresponding to the winning flag of the left reel 42L stops at either the upper line or the lower line. Set the slide table set to stop on the line. If the winning flag is not set, a slip table in which no winning mode is established is set.

  The slip table shown in FIG. 19 is a slip table that is set based on the first winning number when the watermelon winning flag is set. In other words, it can be said that this is the sliding table that is set first when the watermelon winning flag is set. In such a sliding table, for example, when the middle stop switch 73 is pressed while the “cherry” symbol, which is the fourth symbol of the middle reel 42M, has reached the lower line, the middle reel 42M stops without slipping, The “Watermelon” symbol, which is the fifth symbol, stops on the middle line. Also, when the middle stop switch 73 is pressed while the “watermelon” symbol, which is the fifth symbol of the middle reel 42M, has reached the lower line, the middle reel 42M slides by three symbols and becomes the eighth symbol. The “reach” symbol stops on the lower line, and the “watermelon” symbol, the ninth symbol, stops on the middle line. The same applies to the right reel 42R. For example, when the right stop switch 74 is pressed while the “watermelon” symbol, which is the fourth symbol of the right reel 42R, has reached the lower line, the right reel 42R has three symbols. The “reach” symbol as the 7th symbol stops on the lower line, and the “watermelon” symbol as the 8th symbol stops on the middle line. As described above, the “watermelon” symbol is set to stop on the middle line for the middle reel 42M and the right reel 42R.

  However, the left reel 42L is set so that the “watermelon” symbol stops on either the upper line or the lower line. That is, if the left stop switch 72 is pressed while the 7th “bell” symbol is on the lower line, the 9th “watermelon” symbol stops on the upper line and the 8th “replay” If the left stop switch 72 is pressed while the symbol or the number 9 “watermelon” symbol reaches the lower line, the number 9 “watermelon” symbol stops on the lower line. This is a device for diversifying the stop output in consideration of the fact that the stop switches 72 to 74 are generally operated to stop the rotation in the order of the left reel 42L → the middle reel 42M → the right reel 42R. .

  Even when the sliding table is set for the first time, depending on the timing when the stop switch is pressed, the “watermelon” symbol may not stop on the effective line, and so-called missing may occur. This is because the range that can be slid is pre-determined within 190 msec (maximum of 4 symbols) from the timing of pressing the stop switch, and then reaches the lower line from the “watermelon” symbol that has reached the lower line. This is because a section is set in which the interval to the “watermelon” symbol is 5 symbols or more. For example, in the case of the middle reel 42M, from the “Watermelon” symbol of No. 5 to the “Watermelon” symbol of No. 9 is only 3 symbols separated, from the “Watermelon” symbol of No. 9 to the “Watermelon” symbol of No. 5 Are separated by 16 symbols. For this reason, for example, if the middle stop switch 73 is pressed when the 11th “replay” symbol of the middle reel 42M reaches the lower line, even if the middle reel 42M is slid by four symbols, the “watermelon” "The symbol cannot be stopped on the active line."

  On the other hand, the “bell” symbol and the “replay” symbol are arranged on the lower line so that the distance between the symbol that reaches first and the symbol of the same type that reaches next is 4 symbols or less. Each reel 42L, 42M, 42R can be stopped after sliding up to a maximum of 4 symbols from the timing at which each stop switch 72, 73, 74 is operated. , 73 and 74 are operated at any timing, if the bell winning flag or the replay winning flag is set, the combination of the “bell” symbol and the combination of the “replay” symbol are stopped on the active line. Can be made.

  Returning to the description of the slip table setting process, if it is determined in step S801 that the BB winning flag is set, it is further determined in step S804 whether another winning flag is set. If no other winning flag is set, it means that only the BB winning flag is set. Therefore, the processing in steps S802 to S803 described above is performed, and this processing is terminated. On the other hand, when another winning flag is set, it means that the player has won a small role or replay with the BB winning flag carried over. In such a case, the process proceeds to step S805, and the second winning number uniquely corresponding to the set winning flag is set in the winning number storage area of the RAM 153. When the second winning number is set, it means that the BB winning flag and the small role winning flag or the replay winning flag are set. In the subsequent step S806, a sliding table uniquely determined from the value of the second winning number is set in the sliding table storage area of the RAM 153, and this process is terminated.

  At this time, the slot machine 10 sets a sliding table set so that a symbol corresponding to at least one of the BB winning flag and the other winning flag stops on any one of the active lines. More specifically, when the other winning flag is a re-game winning flag, a sliding table is set so that the “replay” symbol has priority over the “7” symbol and stops on the active line. On the other hand, when the other winning flag is the small role winning flag, the “7” symbol is preferentially stopped on the active line, and the “7” symbol cannot be stopped on the active line. A sliding table is set in which the symbol corresponding to the winning flag is set to stop on the active line. Further, when the other winning flag is a bell winning flag which is a small role winning flag, in addition to the above-described setting, both the “7” symbol and the “bell” symbol can be stopped on the active line. In this case, a sliding table set so that both the “7” symbol and the “bell” symbol stop on the active line is set.

  Returning to the description of the lottery process, after the slip table setting process is completed, it is determined in step S709 whether or not a continuous effect is being performed on the auxiliary display unit 15. If the continuous effect is not performed, the process proceeds to step S710, and the continuous effect setting process is performed. Here, the continuous effect is a predetermined display effect over a plurality of games (two games in this embodiment) from the rotation start stage of each reel 42L, 42M, 42R in the auxiliary display unit 15, and the BB winning flag is set. If it is, the BB win is suggested after all reels 42L, 42M, 42R of the final game are stopped, and if not set, the BB is not won after all reels 42L, 42M, 42R are stopped. In the continuous effect setting process, first, a continuous effect lottery is performed to determine whether or not to perform a continuous effect based on the random number latched by the random number counter when the start lever 71 is operated. In the consecutive performance lottery, the winning probability varies depending on the presence or absence of the BB winning flag. The winning probability when the BB winning flag is set is about 1/5, and the winning probability when the BB winning flag is not set is set to 1. In this case, it is about 1/100. That is, the winning probability of the continuous effect lottery is set higher than the BB winning probability regardless of whether or not the BB is won, and the continuous effect lottery is performed regardless of whether or not the small role and replay are won. This is a contrivance to prevent the normal game from becoming monotonous. Then, if the lottery is out of the continuous production lottery, the processing is terminated as it is. The continuous effect command is a command output to the display control device 111, and the display control device 111 starts display control of the auxiliary display unit 15 to start the continuous effect by inputting the command. In addition, when a continuous effect is being performed on the auxiliary display unit 15, a continuous effect end process for setting an end command is performed in step S711, and then this process ends. The end command is a command output to the display control device 111. The display control device 111 recognizes whether or not BB winning is suggested by inputting the command, and the display corresponding to the recognized result. Display control of the auxiliary display unit 15 is performed so that the continuous production ends as a result.

  Next, the reel control processing in step S604 will be described based on the flowchart of FIG.

  In the reel control process, first, in step S901, a rotation start process for starting rotation of the reels 42L, 42M, and 42R is performed. In the rotation start process, it is confirmed whether or not a predetermined time (for example, 4.1 seconds) has elapsed since the start of reel rotation in the previous game, and after performing a wait process that waits until the time elapses. The rotation of each reel 42L, 42M, 42R is started. For this reason, even if the player bets a medal and operates the start lever 71, the reels 42L, 42M, and 42R may not immediately start rotating. In the subsequent step S902, it is determined whether or not any of the stop switches 72 to 74 is pressed to generate a reel stop command, more specifically, whether or not a stop detection signal is input from the stop operating device 182. If the stop detection signal is not input, the process waits until the stop detection signal is input. However, in this embodiment, the period from the start of rotation of each reel 42L, 42M, 42R to the constant speed rotation at a predetermined speed is set as an invalid period, and the stop switches 72˜ Even if 74 is pressed, the stop detection signal from the stop operation device 182 is invalidated. Incidentally, in the present embodiment, a period from when each reel 42L, 42M, 42R starts to rotate until 0.5 seconds elapses is set as an invalid period.

  If any of the stop switches 72 to 74 is pressed in step S902 and a stop command is generated, the process proceeds to step S903, and whether or not the current stop command is the third stop command, that is, only one reel is selected. It is determined whether or not the stop switch is pressed while rotating. If the current stop command is not the third stop command, the slip table first change process is performed in step S904.

  Here, the slip table first changing process will be described with reference to the flowchart of FIG. In the first change process of the slip table, it is determined in step S1001 whether or not the current stop command is the first stop command, that is, whether or not the stop switch is pressed when all the reels are rotating. If it is the first stop command, the first stop change process shown in steps S1002 to S1005 is performed. In the first stop change process, it is confirmed which stop switch is operated in step S1002, and in step S1003, it is determined whether the left stop switch 72 is operated. When the left stop switch 72 is operated, this process is terminated without changing the sliding table. This is because the slip table is set on the assumption that the left stop switch 72 is operated first in the previous slip table setting process (see FIG. 20). On the other hand, when a stop switch other than the left stop switch 72 is operated, it means that the stop switch is operated in an order different from the assumed order. In such a case, the process proceeds to step S1004, and the winning number set in the winning number storage area of the RAM 153 is confirmed. In the subsequent step S1005, the slip table set in the slip table storage area of the RAM 153 is changed to the slipping table for irregular pressing corresponding to the winning number and the operated stop switch, and this processing is ended. In other words, it can be said that the first stop change process is a process of changing the sliding table based on the type of the winning flag that has been set and the operated stop switch.

  If it is determined in step S1001 that the current stop command is not the first stop command, the stop switch is pressed when the stop command is the second stop command, that is, one reel is stopped. Means that In such a case, the second stop change process shown in steps S1006 to S1009 is performed. In the second stop change process, first, in step S1006, the stop switch operated at the time of the first stop command and the stop switch operated at the time of the second stop command, that is, the operation order of the stop switches are confirmed. In subsequent step S1007, it is confirmed what number of symbols has reached the lower line at the timing when the stop detection signal corresponding to the stop switch operated at the time of the second stop command is input. In the following step S1008, it is confirmed whether or not the reaching symbol reaching the lower line is a changed symbol that is uniquely derived from the currently set slip table. If the symbol number of the reaching symbol and the symbol number of the changed symbol match, the process proceeds to step S1009, where the slip table set in the slip table storage area of the RAM 153 is changed to the slip table for line change, and this process ends. . Further, when the symbol number of the reaching symbol and the symbol number of the changed symbol do not match, this processing is terminated as it is. In other words, it can be said that the second stop change process is a process of changing the slide table based on the type of winning flag derived from the slide table and the stop switch operation timing (reel stop start position).

  Here, the first stop change process and the second stop change process will be described taking the case where the watermelon winning flag is set as an example. When the watermelon winning flag is set, in the slip table setting process, the “watermelon” symbol of the middle reel 42M and the right reel 42R is set so that the “watermelon” symbol of the left reel 42L stops at either the upper line or the lower line. Is set to a sliding table (see FIG. 19) set to stop on the middle line.

  When the first stop command is not the left stop switch 72 but the middle stop switch 73, for example, when the middle stop switch 73 is operated at the timing when the “watermelon” symbol of No. 9 reaches the lower line, In the sliding table shown in FIG. 19, not the “Watermelon” symbol of No. 9 but the “Replay” symbol of No. 11 stops on the lower line. That is, the “watermelon” symbol does not stop on the effective line even though the middle stop switch 73 is operated at a timing at which the “watermelon” symbol can be stopped on the effective line. In the first stop change process, the 9th “watermelon” symbol on the lower line is changed to a sliding table that can stop in order to avoid such a problem. More specifically, as with the slip table set in the slip table setting process, the slip table where the “watermelon” symbol of the middle reel 42M stops on any of the effective lines (in the present embodiment, on the middle line or the lower line). Is prepared in advance, and when the middle stop switch 73 is operated, the slide table is changed. The same applies when the first stop command is the right stop switch 74.

  In addition, when the right stop switch 74 is operated as the second stop command in a situation where the “watermelon” symbol is stopped on the upper line of the left reel 42L, the upper line or the lower line is used to establish a watermelon prize. It is necessary to stop the right reel 42R so that the "watermelon" symbol stops above. On the other hand, since the slide table shown in FIG. 19 is a slide table that stops the “watermelon” symbol of the right reel 42R on the middle line, the “watermelon” symbol cannot be stopped on the upper line and the lower line. Accordingly, in the second stop change process, the arrival symbol reaching the lower line is confirmed, and the “watermelon” symbol is changed to a smooth table that can stop on either the upper line or the lower line. For example, when the right stop switch 74 is operated at the timing when the No. 8 “Watermelon” symbol reaches the middle line, the “Watermelon” symbol cannot be stopped on the upper line, so the No. 8 on the lower line. Change to the "slide table" to stop the "watermelon" design.

  Returning to the explanation of the reel control process, after the first change process of the slip table is performed, or when the current stop command is the third stop command, the reaching pattern that has reached the lower line in step S905. Confirm the symbol number of. In step S906, the amount of slip corresponding to the reaching symbol is calculated from the slip table set in the slip table storage area of the RAM 153, and the symbol number of the stop symbol to be actually stopped on the lower line is determined in step S907. In step S908, it is determined whether or not the symbol number of the reaching symbol is equal to the symbol number of the stop symbol. If they are equal, a reel stop process for stopping the reel is performed in step S909. In step S910, it is determined whether or not all the reels are stopped. If all the reels are not stopped, the slip table second change process is performed in step S911.

  Here, the slip table second change process will be described with reference to the flowchart of FIG. In the sliding table second change process, the symbol number of the stopped symbol stopped on the lower line of the currently stopped reel is confirmed in step S1101. In step S1102, it is determined whether or not the symbol number of the stopped symbol matches the symbol number of the changed symbol that is uniquely derived from the currently set slip table. If they do not match, the process is terminated without changing the sliding table. If they match, the process proceeds to step S1103, the slide table set in the slide table storage area of the RAM 153 is changed to a line change slide table, and this process ends. Then, after the slip table second change process is performed, the process returns to step S902 because there is a rotating reel. In other words, the slip table second changing process can be said to be a process of changing the slip table based on the type of winning flag derived from the slip table and the stop position of the reel.

  To explain a specific example, when the replay winning flag is set, in the slip table setting process, the “replay” symbol of the left reel 42L stops at either the upper line or the lower line, and the middle reel 42M and the right A sliding table set so that the “replay” symbol of the reel 42R stops on the middle line is set. For this reason, for example, when the “replay” symbol of the left reel 42L stops on the upper line, in the second change process of the slide table, it is changed to a slide table in which a re-game winning is established on the upper line or the lower right line. . Also, in the second change process of the slip table after stopping the two reels, it is confirmed on which active line the two winning symbols are stopped, and if the winning flag is set, all If the winning flag is not set so that the winning symbol combination can be established when the reels are stopped, the sliding table is changed so that the winning symbol combination is not established when all the reels are stopped.

  Further, in the second change process of the slide table, the slide table is changed not only when changing the effective line for establishing a winning, but also when changing the combination of winning symbols to be established. That is, when the BB winning flag and the small role winning flag are set, it is determined whether or not the “7” symbol is stopped on the active line, and when the “7” symbol is not stopped. The sliding table is changed so that a winning corresponding to the small role winning flag can be established.

  When the BB winning flag is not carried over, the second change process of the slip table performed after stopping the first reel and the second stop change process performed before stopping the second reel ( The sliding table first changing process) is the same as the process of changing the effective line for establishing a prize from the middle line. Therefore, the slot machine 10 is configured to perform only one process according to the type of the winning flag. Specifically, the second change process of the slip table is performed when a winning flag that does not cause a miss such as a bell winning is set, and when a winning flag that can cause a miss such as a watermelon winning is set. 2 Stop change processing is performed. This is a contrivance for reducing the chance of missing while reducing the processing load on the main control device 131.

  Returning to the description of the reel control process, if all the reels are stopped in step S910, the process proceeds to step S912, a payout determination process is performed, and this process ends. The payout determination process is a process of setting the number of medals to be paid out as one of the conditions that a combination of winning symbols is arranged on an active line. Specifically, it is determined whether or not the small role winning is established on the active line. When the small role winning is not established on the active line, the small role winning flag is reset and the expected payout amount of the RAM 153 is stored. Set 0 in the area. When the small role winning is established on the active line, it is determined whether or not the small role winning is a combination of symbols corresponding to the small role winning flag, and when they do not match, an error is displayed by the upper lamp 13 or the like. At the same time, 0 is set in the payout number storage area. If they match, the small combination winning flag is reset, and the number of payouts corresponding to the winning combination is set in the payout planned number storage area of the RAM 153. Further, when the re-game winning is established on the active line, the re-game winning flag is reset and 0 is set in the planned payout number storage area, and the re-game process enabling the re-game is performed. In the re-game process, the number of bets in the game is confirmed, and the same number of bets as the confirmation result is set again. Therefore, when a re-game winning is established, the player can play the next game without reducing the number of medals owned and without inserting medals.

  Next, the medal payout process in step S605 will be described based on the flowchart in FIG.

  In the medal payout process, first, it is determined whether or not the payout number counted by the payout number counter in step S1201 matches the payout number stored in the payout number storage area. If the number of payouts does not match the planned payout number, it is determined in step S1202 whether the count value of the credit counter has reached the upper limit (the number of stored medals is 50). If the upper limit has not been reached, 1 is added to each of the count value of the credit counter and the number of payouts in steps S1203 and S1205. Thereafter, in step S1206, display unit change processing is performed in which the credit display unit 35 and the acquired number display unit 37 are each incremented by one.

  On the other hand, when the count value of the credit counter reaches the upper limit in step S1202, the medal payout rotating plate is driven in step S1204 to pay the medal from the hopper device 91 to the medal tray 18 through the medal discharge port 17. put out. In subsequent step S1205, 1 is added to the number of payouts according to the medal detection signal of the payout detection sensor attached to the hopper device 91. After that, in step S1206, a display unit changing process for adding 1 to the number of acquired number display unit 37 is performed. After performing a display part change process in step S1206, it returns to step S1201 again. If the number of payouts and the number of planned payouts match in step S1201, it is determined in step S1207 whether or not the current gaming state is a bonus game. If it is not a bonus game, the process proceeds to step S1209, and after the payout end process is performed, this process ends. In the payout end process, the payout number storage area and the payout counter value are reset to zero. Note that the value of the acquired number display section 37 is reset when a medal is bet to start the next game. If the current gaming state is a bonus game, the payout number is subtracted from a count value of a remaining acquisition number counter (to be described later) in step S1208, and the number of remaining acquisition number display unit 36 is subtracted. . Thereafter, a payout end process is performed in step S1209, and this process is ended. Note that the process of subtracting the number of remaining acquisition number display part 36 may be performed in the display part changing process in step S1206.

  Next, the bonus game process of step S606 will be described based on the flowchart of FIG.

  Prior to the description of the bonus game process, the bonus game will be described. The BB game is composed of a plurality of RB games. The RB game is composed of 12 JAC games. A JAC game is a game that has a very high probability that a combination of JAC symbols is aligned on an active line, that is, a probability that a JAC winning will be established. When a JAC winning is established in the RB game, the maximum number (15 in this case) of medals is paid out. When the JAC winning is established 8 times, the RB game is ended even before the JAC game is played 12 times. Also, the BB game ends when the number of medals paid out reaches a predetermined number (specifically, 400). When the number of medals paid out reaches a predetermined number during the RB game, not only the BB game but also the RB game is ended. This is a contrivance for suppressing the player's euphoria by giving an upper limit to the number of medals to be paid out during the BB game, and ensuring the soundness of the game. Further, in the present embodiment, a combination of symbols to be transferred to the RB game is not set, and the structure is set to shift to the RB game immediately after the shift to the BB game and immediately after the RB game ends. Therefore, it can be said that the BB game is a game that continuously shifts to the RB game until a predetermined number of medals are paid out.

  In the bonus game process, first, in step S1301, it is determined whether or not the gaming state is a bonus game. When it is not during the bonus game, bonus symbol determination processing shown in steps S1302 to S1305 is performed.

  In this bonus symbol determination process, it is first determined in step S1302 whether or not the BB winning flag is set. If it is not set, this process is terminated. When the BB winning flag is set, the process proceeds to step S1303, where it is determined whether or not the combination of BB symbols has been stopped on the current effective line, and when the combination of BB symbols has not stopped, this processing is terminated. On the other hand, when the combination of BB symbols is stopped on the current effective line, BB start processing is performed in step S1304. In the BB start process, the BB winning flag is reset and the BB setting flag is set to be a BB game which is a kind of bonus game. In addition, 400 is set in the remaining acquisition number counter for counting the number of remaining medals that can be paid out during the BB game, and a process of displaying 400 on the remaining acquisition number display unit 36 is performed. Incidentally, whether or not the current gaming state is a bonus game is determined based on whether or not the BB setting flag is set. In subsequent step S1305, RB start processing is performed, and then this processing is terminated. In the RB start process, 8 is set in the remaining JAC winning counter for counting the number of possible JAC winnings, and 12 is set in the remaining JAC game counter for counting the remaining number of JAC games.

  If it is determined in step S1301 that the gaming state is a bonus game, the process advances to step S1306 to determine whether the combination of JAC symbols has stopped on the active line. When the combination of JAC symbols stops on the active line, 1 is subtracted from the value of the remaining JAC winning counter in step S1307. After that, or when the combination of JAC symbols does not stop on the active line in step S1306, one JAC game has been consumed. Therefore, in step S1308, 1 is subtracted from the value of the remaining JAC game counter. In step S1309, it is determined whether any of the remaining JAC winning counter or the remaining JAC game counter has become zero. If any of them is 0, that is, if the JAC winning is established 8 times or the JAC game is digested 12 times, it means that the RB game end condition is established, so in step S1310 the remaining JAC winning a prize. RB end processing is performed to reset the counter and the remaining JAC game counter values. In a succeeding step S1311, it is confirmed whether or not the count value of the remaining acquisition number counter is zero. If it is not 0, it means that the number of medals paid out during the BB game has not reached the predetermined number and the BB game end condition is not satisfied, and thus the process proceeds to step S1312, and the RB start described above is started. After performing the processing, the present processing is terminated.

  If neither the remaining JAC winning counter nor the remaining JAC game counter is 0 in step S1309, that is, if the JAC winning is not yet established 8 times and the JAC game is not consumed 12 times, step In S1313, it is confirmed whether the count value of the remaining acquisition number counter is 0 or not. If it is not 0, it means that the number of medals paid out during the BB game has not reached the predetermined number and the end condition for the BB game is not satisfied. On the other hand, when the count value of the remaining acquisition number counter is 0, it means that the BB game end condition is satisfied, and therefore, the special game state end process shown in steps S1314 to S1315 is performed. In the special game state end process, first, in step S1314, the above-described RB end process is performed. Thereafter, in step S1315, a BB end process for appropriately resetting a BB setting flag, various counters, and the like or performing an ending process is performed, and this process ends. In addition, even when the count value of the remaining acquisition number counter is 0 in step S1311, it means that the BB game end condition is satisfied. Therefore, in step S1315, the BB end process is performed, and this process ends. To do.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  A power supply line ELN3 for supplying power to the RAM 153 of the main control device 131 is provided between the connectors CN1 and CN2 of the signal line LN2 for outputting a start detection signal. Accordingly, when the signal line LN2 and the harness H that connects the relay board 165 and the main control device 131 are removed in order to connect the signal output device to the main control device 131, power is not supplied to the RAM 153. Therefore, a signal output device that outputs a start detection signal, a stop detection signal, and a medal detection signal is connected to the main control device 131, and winning information (BB winning flag) and BB gaming state information (BB setting) for the BB role are connected to the RAM 153. Flag) is stored, the power supply to the RAM 153 is stopped when the signal output device is removed and replaced with a regular signal line, and the stored winning combination information and BB gaming state information are deleted. . Therefore, it is possible to suppress the act of connecting the signal output device to the main control device 131 and illegally making a transition to the BB game or making a transition to the BB game.

  In particular, when the signal output device is connected, the power supply line ELN3 that supplies power to the RAM 153 is removed. Therefore, even if a signal output device capable of supplying power is used, an action based on the signal output device can be suppressed. it can.

  The signal line is not replaceable on the terminal side of the main control board 131a with respect to the signal line LN2. This makes it impossible (or difficult) to replace the main control board 131a with the signal output device at the terminal side of the signal line LN2, and to the signal output device at the terminal side. It is possible to suppress the act of trying to replace That is, when connecting the signal output device, it is necessary to remove the signal line LN2 or the harness H, and the act of using the signal output device can be suppressed as described above.

  The power from the backup capacitor 181b is also supplied through the power line ELN3 provided between the connectors CN1 and CN2 of the signal line LN2. Thus, the signal output device is connected to the main control device 131 in a state where the power of the slot machine 10 is cut off, and the winning information (BB winning flag) and BB gaming state information (BB setting flag) of the BB role are stored in the RAM 153. Even if the signal is stored, when the signal output device is removed and the signal line LN2 and the harness H are connected, the stored winning combination information and BB gaming state information are deleted. Therefore, this act can be suppressed.

  The backup capacitor 181b was mounted on the start operation board 181a. Thereby, the signal line LN2 and the power supply line ELN3 can be connected to the connectors CN1 and CN2 without difficulty.

(Second Embodiment)
In the present embodiment, the configuration relating to the supply of power to the RAM 153 is different from that of the first embodiment. Therefore, the configuration will be described in detail below. In the following description, differences from the first embodiment will be mainly described, and description of the same configuration will be basically omitted. FIG. 26 is a block circuit diagram in the present embodiment.

  As shown in FIG. 26, in the present embodiment, as in the first embodiment, a main control device 131, a power supply device 161, a relay board 165, and a start operation device 181 are provided. A start lever 71 is connected to the start operation board 181a of the start operation device 181, and the signal line LN1 connecting the start operation board 181a and the start lever 71 is fixed by solder or the like and is provided in a non-detachable state. ing. The start operation board 181a is connected to the relay board 165 via a signal line LN2, and the signal line LN2 is detachably attached via connectors CN1 and CN2. The relay board 165 is connected to the main control board 131a of the main controller 131 via a harness H, and the harness H is detachably attached via connectors CN7 and CN8. Here, the connector CN8 of the harness H is connected to a connector CN9 (corresponding to an input means) of the main control board 131a. The power supply unit 161a of the power supply device 161 is connected to the main control board 131a of the main control device 131 through the power supply line ELN1, and power is supplied to the CPU 151 of the main control board 131a through the power supply line ELN1. . However, the power supplied to the CPU 151 is not supplied to the RAM 153.

  In the present embodiment, a connection confirmation signal line LLN1 is provided between the connectors CN1 and CN2 in place of the power supply line ELN3, and a connection confirmation signal line LLN2 is provided in the harness H instead of the power supply line. Yes. Further, a relay circuit EC is formed on the relay board 165 so as to connect both the connection confirmation signal lines LLN1 and LLN2. As a result, a connection confirmation signal is transmitted from the starting operation board 181a to the main control board 131a via the relay board 165. In this case, the connection confirmation signal line LLN1 is grounded in the start operation board 181a, and a ground potential (L level) is transmitted as a connection confirmation signal.

  The power supplied from the power supply device 161 via the power supply line ELN1 is branched in the main control board 131a, and is supplied via the backup power generation circuit 211 and the switching circuit 212 mounted on the main control board 131a. It is supplied to the VBB terminal which is a terminal for backup power source of the CPU 151. The switching circuit 212 includes a MOSFET 212a and a pull-up resistor 212b. The MOSFET 212a is of a type in which current flows between the source and drain when the input voltage of the gate terminal is at L level, and no current flows between the source and drain when it is at H level. The gate terminal of the MOSFET 212a is connected to the backup power generation circuit 211 via the pull-up resistor 212b and to the connection confirmation signal line LLN2 of the harness H.

  With the above configuration, a signal output device that outputs a start detection signal, a stop detection signal, and a medal detection signal is connected to the main control board 131a, and a BB prize is generated by outputting each signal. It is possible to suppress cheating.

  That is, in the present embodiment, as described above, the connection confirmation signal from the start operation board 181a to the main control board 131a via the connection confirmation signal line LLN1 provided between the connectors CN1 and CN2 connecting the signal line LN2. Is entered. Here, since the connection confirmation signal line LLN1 is grounded in the start operation board 181a, when the signal line LN2 and the harness H are connected, the main control board 131a is connected to the L level as a connection confirmation signal. Is entered. As a result, the input voltage at the gate terminal of the MOSFET 212a becomes L level, current flows between the source and drain of the MOSFET 212a, and power is supplied to the VBB terminal. On the other hand, in the state where one of the signal line LN2 and the harness H is disconnected, the connection confirmation signal is not input to the main control board 131a. As a result, the input voltage of the gate terminal of the MOSFET 212a becomes H level because the gate terminal is pulled up to the output voltage of the backup power generation circuit 211. Then, no current flows between the source and drain of the MOSFET 212a, and power is not supplied to the VBB terminal.

  That is, when the harness H or the signal line LN2 is removed and the signal output device is connected, the connection confirmation signal is not input to the main control board 131a, and the power supply to the RAM 153 is stopped by the MOSFET 212a. Since the RAM 153 does not function, the CPU 151 cannot perform various processes, and the above-described fraudulent acts cannot be performed. Even if a signal for confirming connection is output from the signal output device, the signal for confirming connection is lost when the signal output device is disconnected and the connector CN2 or harness H is connected. The power is not supplied to the RAM 153 by the MOSFET 212a. Therefore, the winning information of the BB combination stored in the RAM 153 is erased, and the illegal act cannot be performed.

  It is also assumed that the signal output device is replaced with respect to the main control board 131a on the terminal side of the signal line LN2. That is, it is assumed that the signal line LN1 that connects the start lever 71 and the start operation board 181a is removed and the signal output device is connected to the start operation board 181a instead. On the other hand, in the present embodiment, the signal line LN1 is fixed to the starting operation board 181a with solder or the like, and is in a state in which it cannot be removed. Therefore, it is impossible (or difficult) to replace the main control board 131a with the signal output device on the terminal side of the signal line LN2, and the signal output device on the terminal side can be changed. The act of trying to replace can be suppressed.

  According to the second embodiment described in detail above, the following excellent effects are obtained.

  A connection confirmation signal line LLN1 for transmitting a connection confirmation signal from the start operation board 181a is provided between the connectors CN1 and CN2 of the signal line LN2 for outputting the start detection signal, and the connection confirmation signal is used as the connection confirmation signal. Accordingly, a switching circuit 212 for controlling power supply to the RAM 153 is provided. Thereby, in order to connect the signal output device to the main controller 131, the signal line LN2 that connects the start operation board 181a and the relay board 165, and the harness H that connects the relay board 165 and the main controller 131 are provided. If it is removed, the connection confirmation signal is not transmitted accordingly, and the power supply to the RAM 153 is stopped by the MOSFET 212a of the switching circuit 212. Therefore, a signal output device that outputs a start detection signal, a stop detection signal, and a medal detection signal is connected to the main control device 131, and winning information (BB winning flag) and BB gaming state information (BB setting) for the BB role are connected to the RAM 153. Flag) is stored, the power supply to the RAM 153 is stopped when the signal output device is removed and replaced with a regular signal line, and the stored winning combination information and BB gaming state information are deleted. . Therefore, it is possible to suppress the act of connecting the signal output device to the main control device 131 and illegally making a transition to the BB game or making a transition to the BB game.

  In particular, the connection confirmation signal line LLN1 or the harness H (connection confirmation signal line LLN2) that transmits a connection confirmation signal when the signal output device is connected is removed. For this reason, even if a signal output device capable of outputting a connection confirmation signal is used, power supply to the RAM 153 is stopped when the connection confirmation signal is not transmitted when the signal output device is connected. Therefore, the action based on it can be suppressed.

  The connection confirmation signal line LLN1 is grounded in the start operation board 181a, and power is supplied to the RAM 153 when the L level is input to the main control board 131a as a connection confirmation signal. By doing so, it is not necessary to provide a circuit for generating a connection confirmation signal on the starting operation board 181a, and the configuration for outputting the connection confirmation signal can be simplified.

  The signal line is not replaceable on the terminal side of the main control board 131a with respect to the signal line LN2. This makes it impossible (or difficult) to replace the main control board 131a with the signal output device at the terminal side of the signal line LN2, and to the signal output device at the terminal side. It is possible to suppress the act of trying to replace That is, when connecting the signal output device, it is necessary to remove the signal line LN2 or the harness H, and the act of using the signal output device can be suppressed as described above.

  The power supply from the backup power generation circuit 211 is also controlled by the switching circuit 212. Thus, the signal output device is connected to the main control device 131 in a state where the power of the slot machine 10 is cut off, and the winning information (BB winning flag) and BB gaming state information (BB setting flag) of the BB role are stored in the RAM 153. Even if the signal is stored, when the signal output device is removed and the signal line LN2 and the harness H are connected, the stored winning combination information and BB gaming state information are deleted. Therefore, this act can be suppressed.

  The power supplied from the power supply unit 161 a of the power supply device 161 is branched in the main control board 131 a and supplied to the RAM 153 via the backup power generation circuit 211 and the switching circuit 212. Accordingly, it is not necessary to provide a power line (harness) for supplying power to the RAM 153 between the power supply unit 161a and the RAM 153, and the configuration of the power supply system can be simplified. In addition, since it is not necessary to provide such a power supply line, the length of the power supply path between the power supply unit 161a and the RAM 153 can be shortened, and electromagnetic noise mixed in the power supply to the RAM 153 is reduced. For this reason, inconveniences such as unintentionally changing information stored in the RAM 153 due to power supply noise can be avoided.

  The backup power generation circuit 211 and the switching circuit 212 are mounted on the main control board 131a. Thereby, the components of the power supply system are collected on the main control board 131a, and the configuration can be simplified.

(Third embodiment)
In the first embodiment, the signal line LN2 and the power supply line ELN3 are integrated into one connector CN2, and the connector CN2 is connected to the connector CN10 of the relay board 165. In this embodiment, the structure of such a connector is used. Is different. Therefore, the structure of the connector according to the following will be described in detail with reference to FIG. In the following description, differences from the first embodiment will be mainly described, and description of the same configuration will be basically omitted. 27A and 27B are diagrams showing the structure of the connector in the present embodiment, where FIG. 27A is an exploded perspective view showing each connector exploded, and FIG. 27B is a sectional view taken along line AA in FIG.

  As shown in FIG. 27, the connector CN13 provided on the relay substrate 165 has a recess 221 that is open to one side, and a row of connection pins P formed of a conductive metal are formed in the recess 221. Are arranged in line. Further, the signal line LN2 and the power supply line ELN3 have connectors CN14 and CN15, respectively, and are connected to a terminal T which is provided in the inside and formed of a conductive metal. Each of the connectors CN14 and CN15 has a substantially rectangular parallelepiped shape by engaging both, and can be fitted into the recess 221 of the connector CN13 of the relay board 165 in the engaged state. Then, when they are fitted, the terminals T of the connectors CN14 and CN15 come into contact with the connection pins P provided on the connector CN13, and the signal line LN2 and the power supply line ELN3 are electrically connected to the relay board 165. .

  Here, the connectors CN14 and CN15 of the signal line LN2 and the power supply line ELN3 have a staircase shape in which the opposite sides are engaged with each other, and specifically have protrusions 222 and 223. When the protrusions 222 and 223 are viewed from the direction in which the connectors CN14 and CN15 are fitted to the connector CN13 of the relay board 165, the protrusions 223 of the connector CN15 of the power supply line ELN3 are signal lines LN2. It is formed so as to overlap with the protrusion 222 of the connector CN14. At this time, in order to remove the connector CN14 of the signal line LN2 from the connector CN13 of the relay board 165, it is necessary to remove the CN15 of the power line ELN3 first or to remove both at the same time. Therefore, in this case, it can be said that the removal of the connector CN14 of the signal line LN2 is regulated by the connector CN14 of the power supply line ELN3.

  With the above configuration, a signal output device that outputs a start detection signal, a stop detection signal, and a medal detection signal is connected to the main control board 131a, and a BB prize is generated by outputting each signal. It is possible to suppress cheating.

  That is, in the present embodiment, as described above, the removal of the connector CN14 of the signal line LN2 is restricted by the connector CN15 of the power supply line ELN3, and the connector CN14 that connects the signal line LN2 without removing the connection of the power supply line ELN3 is provided. It cannot be removed. That is, in order to disconnect the signal line LN2 and connect the signal output device, it is necessary to remove the connector CN15 of the power supply line ELN3, and accordingly, power is not supplied to the RAM 153. Even if power is supplied from the signal output device, the connector CN15 of the power supply line ELN3 is removed when the signal output device is disconnected and the connector CN2 is connected. The power is not supplied to the RAM 153. Therefore, the winning information of the BB combination stored in the RAM 153 is erased, and the illegal act cannot be performed.

  According to the third embodiment described in detail above, the following excellent effects are obtained.

The connectors CN14 and CN15 of the signal line LN2 and the power supply line ELN3 are connected to the relay board 1.
In a state of being connected to the 65 connector CN10, due to the interference between the protrusions 222 and 223, only the connector CN14 of the signal line LN2 cannot be pulled out without pulling out the connector CN15 of the power supply line ELN3. In other words, if the connector CN14 of the signal line LN2 is pulled out from the connector CN10, the connector CN15 of the power supply line ELN3 is always pulled out. Therefore, the same effect as that of the first embodiment can be obtained even though the signal line LN2 and the power supply line ELN3 have the individual connectors CN14 and 15, respectively.

(Other embodiments)
In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (1) FIG. 28 is a diagram showing a modification of the first embodiment. In the modification shown in FIG. 28, a backup capacitor 191 is provided in the power supply device 161. As a result, the configuration related to the supply of power can be integrated into the power supply device 161. Even in this case, the power to the RAM 153 is supplied via the power line ELN3 provided between the connectors CN1 and CN2 of the signal line LN2 from the start operation board 181a. Similarly, it is possible to suppress the act of connecting the signal output device to the main control device 131 and storing the BB winning information (BB winning flag) and the BB gaming status information (BB setting flag) in the RAM 153.

  (2) FIG. 29 is a diagram showing a modification of the second embodiment. In the modification shown in FIG. 29, a switching circuit 214 different from that in the second embodiment is provided on the main control board 131a, and the switching circuit 214 includes a MOSFET 214a and a pull-down resistor 214b. The MOSFET 214a is of a type in which a current flows between the source and the drain when the input potential of the gate terminal is at the H level, and no current flows between the source and the drain when the input potential is the L level. The gate terminal of the MOSFET 214a is grounded via the pull-down resistor 214b and is connected to the connection confirmation signal line LLN2 of the harness H. Further, the connection confirmation signal line LLN1 is connected to the power supply line ELN4 extending from the power supply unit 161a of the power supply device 161 in the start operation board 181a, and the H level (5 V) is used as the connection confirmation signal. It is output to 131a.

  In this case, in a state where the signal line LN2 and the harness H are connected, the input voltage of the gate terminal of the MOSFET 212a becomes H level, current flows between the source and drain of the MOSFET 214a, and power is supplied to the VBB terminal. The On the other hand, in the state where the signal line LN2 or the harness H is disconnected, the connection confirmation signal is not input, and the input voltage of the gate terminal of the MOSFET 214a becomes L level by the pull-down resistor 214b. As a result, no current flows between the source and drain of the MOSFET 214a, and power is not supplied to the VBB terminal.

  Even in such a configuration, the supply of power to the RAM 153 is stopped by the switching circuit 214 as the connection confirmation signal (H level) is not transmitted when the signal line LN2 and the harness H are removed. . For this reason, as in the second embodiment, the signal output device is connected to the main control device 131, and the winning information (BB winning flag) and the BB gaming state information (BB setting flag) of the BB role are stored in the RAM 153. Can be suppressed.

  (3) FIG. 30 is a diagram showing a modification of the third embodiment, in which (a) is an exploded perspective view showing each connector exploded, and (b) is a line BB in (a). It is sectional drawing. In this modification, the structure for restricting the removal of the connector of the signal line LN2 is different depending on the connector of the power supply line ELN3.

  As shown in FIG. 30, the connector CN16 provided on the relay board 165 is formed with a recess 231 having a cross-sectional opening on one side, and the connection pins P are arranged in a line at substantially equal intervals. Yes. Further, the signal line LN2 and the power supply line ELN3 have connectors CN17 and CN18, respectively, and are connected to terminals T formed of conductive metal provided in the connectors CN17 and CN18.

  Here, the connector CN17 of the signal line LN2 has a shape in which two rectangular parallelepipeds are stacked in the removal direction. When the cuboid on the upper side in the removal direction is referred to as the upper step portion 233, and the cuboid on the lower side in the removal direction is referred to as the lower step portion 234, the lower step portion 234 is larger than the upper step portion 233 when viewed from the removal direction. It has been. On the other hand, the connector CN18 of the power supply line ELN3 penetrates in the removal direction, and the connector CN17 can be included in a state where the connector CN18 and the connector CN17 of the signal line LN2 are fitted to the connector CN16 of the relay board 165. The upper step 233 and the lower step 234 respectively have an upper step hole 235 and a lower step hole 236 having substantially the same shape. At this time, since the upper hole portion 235 of the connector CN18 is smaller than the lower step portion 234 of the connector CN17, the connector 17 can be removed while the connectors CN17 and 18 are fitted to the connector CN16 of the relay board 165. It can be said that it is regulated by CN18. Further, the connector CN18 is provided with a slit portion 237 from the outer edge of the long side toward the hole portions 235 and 236, so that the signal line LN2 can be inserted into the upper step hole portion 235 and the lower step hole portion 236. .

  Even in such a configuration, in order to remove the connector CN17 of the signal line LN2, it is necessary to remove the connector CN18 of the power line ELN3 first or at the same time. Therefore, when the connector CN17 of the signal line LN2 is removed in order to connect the signal output device that outputs an illegal signal to the main controller 131, the connector CN18 of the power supply line ELN3 is removed, and the power is not supplied to the RAM 153. Therefore, fraudulent acts using such a signal output device can be suppressed. In particular, compared with the third embodiment, in this modification, the connector CN18 of the power supply line ELN3 overlaps with the connector CN17 of the signal line LN2 over a wider range, so that the removal of the connector CN17 is remarkably restricted. .

  (4) In the third embodiment, the signal line LN2 and both connectors CN14 and CN15 of the power supply line ELN3 are connected to one connector CN9 provided on the relay board 165. However, the signal line LN2 and the power supply line are connected. Connectors corresponding to the connectors CN14 and CN15 of ELN3 may be provided on the relay board 165, and the connectors CN14 and CN15 may be individually connected. Even in this case, the effect described in the third embodiment can be obtained by restricting the removal of the connector CN14 of the signal line LN2 by the connector CN15 of the power supply line ELN3 with each connector connected. be able to.

  (5) In the first embodiment, the power supply line ELN3 for supplying power to the RAM 153 is provided between the connectors CN1 and CN2 of the signal line LN2 from the start operation board 181a. However, this may be changed. For example, the power supply line ELN3 may be provided between the connectors CN3 and CN4 of the signal line LN4 from the stop operation board 182a, or may be provided between the connectors CN5 and CN6 of the signal line LN6 from the selector board 84a.

  In this case, by providing the power supply line ELN3 between the connectors CN5 and CN6 of the signal line LN6 from the selector board 84a, it is possible to more surely suppress an illegal act using the signal output device. That is, when the power supply line ELN3 is provided between the connectors CN1 and CN2 of the signal line LN2 from the start operation board 181a and between the connectors CN3 and CN4 of the signal line LN4 from the stop operation board 182a, the power supply line ELN3 is provided. By operating the start lever 71 and the stop switches 72 to 74 without removing the signal line, the 153 role winning information (BB winning flag) and BB gaming status information (BB setting flag) are stored in the RAM 153. This is because the act of making it possible becomes possible.

  Further, since the start lever 71 and the stop switches 72 to 74 are actively operated by the player, the start operation device 181 and the stop operation device 182 are more likely to fail than the selector 84. If the start operation device 181 or the stop operation device 182 breaks down, power is not supplied to the RAM 153, so that the game cannot be performed. On the other hand, by providing the power supply line ELN3 between the connectors CN5 and CN6 of the signal line LN6 from the selector board 84a, the signal output device is connected to the main controller 131 while suppressing the occurrence of the inconvenience. The act of storing the winning information (BB winning flag) and the BB gaming state information (BB setting flag) of the BB combination in the RAM 153 can be suppressed.

  (6) In the first embodiment, the signal lines LN2, LN4, and LN6 may be attached to the substrates 181a, 182a, 84a, and 165 in a non-detachable state. For example, a configuration in which a caulking structure that cannot be attached to and detached from the connector for connecting the signal lines LN2, LN4, and LN6 is considered. In this case, a person who intends to cheat using the signal output device connects the signal output device to the main control device 131 by removing the harness H. Therefore, in such a configuration, power may be supplied to the RAM 153 via the relay substrate 165 without using the start operation substrate 181a. In this case, a backup capacitor may be provided on the relay substrate 165.

  (7) In the first embodiment, when the signal lines LN2, LN4, and LN6 are removed from the substrates 181a, 182a, 84a, and 165, the traces may remain. As an example of the signal line LN2, for example, a seal is pasted so as to straddle the connector CN2 of the signal line LN2 and the connector CN10 of the relay board 165. When the seal is peeled off, the adhesive is transferred to the connectors CN2 and CN10 so that the trace remains.

  Further, for example, a sealing portion is formed in each of the connectors CN2 and CN10. Then, when connecting the connectors CN2 and CN10, the connecting parts are attached to the sealing parts in a state in which the connecting parts cannot be detached (for example, the connecting parts are press-fitted into the press-fitting parts formed in the sealing parts), and the sealing parts are mutually connected. Connect. In this case, in order to remove the signal line LN2, it is necessary to destroy the sealing portion, and there remains a trace that the signal line LN2 has been removed.

  (8) The signal line LN1 that connects the start lever 71 and the start operation board 181a may be connected to the start lever 71 or the start operation board 181a via a connector. However, in order to make the signal line LN1 difficult to attach and detach, it is necessary to provide the connector with the crimping structure (6), the structure leaving the trace (7), and the like.

  In addition, the connection configuration via the connector is configured with respect to the signal line LN3 that connects the stop switches 72 to 74 and the stop operation board 182a, and the signal line LN5 that connects the inserted medal detection sensor 84b and the selector board 84a. May be applied.

  (9) In the first embodiment, the RAM 153 includes the backup area 153a. However, the RAM 153 does not include the backup area 153a, and the data is stored without being saved when the power is shut off. It is good also as composition to do. In this case, the backup capacitor 181b functions as a memory holding power source.

  (10) In the case of an illegal act using the signal output device, the signal line of the reel index sensor 55 provided in the reel unit 41 is also disconnected together with the signal lines LN2, LN4, LN6, and the signal from the reel index sensor 55 Is output to the main control device 131. In this case, when the signal output device is connected, if the signal line of the reel index sensor 55 must be removed, a power line is provided between the signal line connectors of the reel index sensor 55, A configuration may be adopted in which power is supplied to the RAM 153 through a power supply line. Note that when connecting the signal output device, the configuration in which the signal line of the reel index sensor 55 must be removed is the configuration in which the signal line is connected to the relay board 165 in the first embodiment. In addition, the signal lines connected to the relay board 165 and the signal lines LN2, LN4, and LN6 in the first embodiment are not removable, difficult to remove, or traces are left when removed. A configuration that is attached in a state is conceivable.

  (11) In the first embodiment, the power supply line ELN3 is provided between the connectors CN1 and CN2 of the signal line LN2. Instead, one end of the power supply line ELN3 is connected to the connector CN2 and the other end is connected. It is good also as a structure connected to another connector.

  (12) In the configuration described in (1), (5) to (11) above, a connector is provided for each of the signal line LN2 and the power supply line ELN3, and the connector of the signal line LN2 is removed by the connector of the power supply line ELN3. You may make it regulate. Even in this case, the effects described in (1) and (5) to (11) can be achieved.

  (13) The configuration described in (3) to (12) above is applied to a slot machine provided with a switching circuit 212 that controls the supply of power to the RAM 153 according to a connection confirmation signal. The connection confirmation signal line LLN1 for transmitting the above signal may be provided in place of the power supply line ELN3. Even in this case, the effects described in (3) to (12) can be achieved.

  (14) In each of the above-described embodiments, a privilege for paying out medals is awarded when a small role winning is established. However, the present invention is not limited to this configuration, and some privilege is granted to the player. Any configuration may be used. For example, a configuration in which prizes other than medals are paid out when a small winning combination is established. Further, in a slot machine that does not have an actual medal insertion or medal payout function and manages credits owned by a player, an increase in credited medals corresponds to provision of a privilege.

  (15) In each of the embodiments described above, a belt on which a pattern is printed is attached to the outer peripheral surface of the cylindrical skeleton member 50. However, the cylindrical skeleton member and the belt are integrally formed, and the outer peripheral surface of the belt is formed. It is good also as a structure which affixes a symbol separately. In such a case, the integrally formed outer peripheral surface corresponds to an endless belt.

  (16) In each of the above embodiments, the medal payout is not performed when the “7” symbols as the state transition symbols are aligned on the active line. However, the medal payout may be performed.

  (17) In each of the above embodiments, a slot machine having three reels arranged in parallel and having five lines as effective lines has been described. However, the present invention is not limited to this configuration. For example, five reels are arranged in parallel. Or a slot machine having seven effective lines.

  (18) In each of the above embodiments, the so-called A type slot machine has been described. However, the B type, C type, A type and C type composite type, B type and C type composite type, RT game, The present invention may be applied to any slot machine such as a type equipped with a CT game, and in any case, it is obvious that the same effects as those of the above-described embodiments can be obtained. Note that the bonus winning in each of these types includes BB winning, RB winning, SB winning, RT winning, CT winning and the like.

  In addition, in a slot machine equipped with an RT game or a CT game, when transitioning to an RT game or a CT game, the gaming state information is stored in the RAM 153, and the RT game is executed by the CPU 151 based on the stored gaming state information. Or CT game is executed. Therefore, it is assumed that the signal output device is connected to the main control device 131 to shift to the RT game or the CT game. On the other hand, by applying the present invention, it is possible to suppress the act of connecting to the signal output device and shifting to the RT game or CT game, and further the gaming state corresponding to the RT game or CT game in the RAM 153 Even if the information is stored, the game state information stored in the RAM 153 is erased when the signal output device is switched to the regular signal line.

  (19) The symbols of the reels 42L, 42M, and 42R are not limited to pictures, numbers, characters, and the like, but may be geometric lines or figures. In addition, the design can be configured by light, color, or the like, the design can be configured by a three-dimensional shape or the like, and the design can be configured by combining these. That is, it is sufficient that the symbol has a function as information having identification (identification information).

  (20) In each of the embodiments described above, an example in which the slot machine 10 is embodied is shown, but the present invention may be applied to a gaming machine of a type in which a slot machine and a pachinko machine are fused. That is, in the slot machine, instead of the medal insertion and medal payout functions, a gaming machine having a ball insertion and ball payout function such as a pachinko machine may be used. If such a gaming machine is used in place of a slot machine, only a ball can be handled as a gaming value in the gaming hall. Therefore, the gaming value seen in the current gaming hall in which pachinko machines and slot machines are mixed is used. Problems such as the burden on equipment due to the separate handling of medals and balls and restrictions on the location of the gaming machine can be solved.
