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.

Even if the game state information is stored, if the connection between the control board device and the signal output device is released so as to return to the connection state by the connection unit, the power supply for shutoff from the power supply means for shutoff to the information storage means The supply is stopped, and the stored information on the winning combination and gaming state information is deleted. Therefore, this act can be suppressed.

  Means 24. A gaming machine according to claim 23, wherein the power supply means for shutdown is mounted on the control board device.

  According to the means 24, the power supply line (harness) connecting the power supply means for interruption and the information storage means becomes unnecessary by mounting the power supply means for interruption on the control board device. In addition, since the power supply means for shutoff can be integrated into the control board device together with other electronic components, the configuration of the power supply system can be simplified.

Means 25. A pattern display device (reel unit 41) for variably displaying the pattern;
Receiving means for receiving game media (medal slot 75, selector 84);

An electrical path is provided between the relay unit and the control board device, and power is not supplied to the control board device while the electrical path is interrupted.
The electrical wiring (power supply line ELN3, connection confirmation signal line LLN1, etc.) that forms the electrical path and the output side signal line from the relay unit for the relayed detection signal are connected to the relay unit side and the control board device side. Configured as a connection unit (harness H, harness H1, etc.) by connecting between connectors (connectors CN9, CN10, connectors CN31, CN32, etc.)
Provided with trace means (cover members 220, 260) for leaving a trace when the input signal lines (signal lines LN2, LN4) of the relayed detection signal to the relay section are removed from the relay section. A featured gaming machine.

  In the gaming machine of the means 25, a predetermined number of game media are received by the receiving means, and the starting operation means is operated to start variable display of the picture on the picture display device. Further, the variable display of the pattern is stopped by operating the stop operation means. And a privilege is provided according to a stop picture.

  In this configuration, a relay unit is provided, and at least one of the detection signals input to the control board device is relayed. In addition, an electrical path is provided between the relay unit and the control board device, and power is not supplied to the control board device while the electrical path is interrupted. In this case, the output signal line of the detection signal relayed by the relay unit and the electrical wiring forming the electrical path are configured as a connection unit. Accordingly, when the connection unit is removed in order to output an illegal signal from the signal output device to the control board device, power is not supplied to the control board device.

  In particular, the means of this means is provided with trace means, and if the input side signal line is removed from the relay section, the trace remains. For this reason, it becomes possible to hesitate to act to connect the signal output device by removing the input signal wire from the relay section, and the signal output device can be connected by removing the input signal line without removing the connection unit. It can be suppressed.

  With the above configuration, even if the signal output device is connected to the control board device and a game is attempted without actually inserting the game medium or operating various operation means, power is not supplied to the control board device. You will not be able to play games. Therefore, it is possible to suppress the act of playing a game without connecting a signal output device and actually performing the insertion of the game medium or the operation of various operation means.

  In addition, the structure which makes the detection signal relayed in a relay part at least one among a medium detection signal, a starting detection signal, and a stop detection signal can be considered. However, when the fraudulent action is performed by outputting a fraud signal corresponding to a detection signal other than the detection signals from the signal output device, the relay unit may relay the detection signal.

  Further, by applying any one of the above-described means 2 to 24 to the means 25, the effect of each means can be obtained.

  As shown in FIGS. 1 to 5, the slot machine 10 includes a housing 11 that forms an outer shell thereof. The casing 11 includes a top plate 11a, a bottom plate 11b, a back plate 11c, a left plate 11d, and a right plate 11e formed in a wooden plate shape, and the adjacent plates 11a to 11e are fixed by a fixing means such as adhesion. Thus, it is formed in a box shape with the front surface opened as a whole. In addition, each board 11a-11e may be comprised with a synthetic resin panel or a metal panel other than being comprised with a wooden panel, or it is comprised by forming in the box shape integral with a synthetic resin material or a metal material. May be. The casing 11 configured as described above is attached by, for example, driving nails against a so-called island facility at the time of installation in the game hall.

  A front door 12 as a front open / close door is attached to the front side of the housing 11 so as to be openable and closable. That is, the left side plate 11d of the housing 11 is provided with a pair of upper and lower support shafts 25a and 25b. Each of the support shafts 25a and 25b includes a tapered shaft portion that protrudes upward. On the other hand, the front door 12 is provided with support fittings 26a and 26b having insertion holes into which the shaft portions of the support shafts 25a and 25b are inserted corresponding to the support shafts 25a and 25b. Then, the support brackets 26a and 26b are arranged above the support shafts 25a and 25b, and the front door 12 is lowered, whereby the shaft portions of the support shafts 25a and 25b are inserted into the insertion holes of the support brackets 26a and 26b. It is assumed that it was done. Thereby, the front door 12 is supported so as to be rotatable about an opening / closing axis extending in the vertical direction connecting the both support shafts 25a and 25b with respect to the housing 11, and the front opening side of the housing 11 is opened by the rotation. It can be closed or closed.

  The front door 12 is brought into a locked state that cannot be opened by a locking device provided on the rear surface. Further, a key cylinder 20 serving as an unlocking operation unit is provided at the upper right side of the front door 12. 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 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. 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 with 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 that has been activated, that is, when the symbol is stopped in a predetermined combination on the activated line, a prize is awarded, and a payout process for a predetermined medal number or a bonus game such as a BB game that is in 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.

  Below the game panel 30, an operation unit 70 is provided that bulges forward of the slot machine 10 from the game panel 30 and is provided with various operation means. Thus, the operability of various operation means is improved by the operation unit 70 bulging forward.

  The start lever 71 which is one of the operation means is provided on the left side of the front surface 70 a of the operation unit 70. 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 on the front surface 70a of the operation unit 70, button-like stop switches 72, 73, 74 that are operated to individually stop the rotating reels 42L, 42M, 42R are provided. Yes. 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 right side of the operation unit 70, a medal insertion slot 75 for inserting a medal as an investment value is provided so as to protrude upward from the upper surface 70 b of the operation unit 70. 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. 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 to the right of the stop switches 72 to 74 on the front surface 70 a of the operation unit 70. 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 left side of the upper surface 70b of the operation unit 70, there is provided a button-shaped max insertion switch 77 for inserting three credited virtual medals as investment values at a time. Note that the max insertion switch 77 has a built-in lamp as a light emitting member (not shown) in order to urge that the maximum number of medals that can be inserted per game (three) has not been reached. The lamp is lit in a situation where the switch operation of the max insertion switch 77 is valid to prompt the operation of the switch 77. However, when no credited virtual medal exists or three medals have already been inserted. Turns off under 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 on the front surface 70 a of the operation unit 70. 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, 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, and the third medal is a medal. 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.

FIG. 14 is an explanatory diagram for explaining the configuration of the cover member 220 around the A line, and FIG. 14 is an explanatory diagram for explaining the configuration of the cover member 220 around the BB line of FIG.

  The start operating device 181 and the stop operating devices 191 to 193 have housings 183 and 197 to 199, respectively, and the operation boards 182 and 194 to 196 are accommodated in the housings 183 and 197 to 199, respectively. The connector CN3 included in the start operation board 182 and the connector CN7 included in the stop operation boards 194 to 196 are accommodated in the housings 183 and 197 to 199, respectively.

  As described above, the start lever 71 of the start operation device 181 and the stop switches 72 to 74 of the stop operation devices 191 to 193 are provided in the operation unit 70 of the front door 12. In this case, the housing 183 of the start operation device 181 and the housings 197 to 199 of the stop operation devices 191 to 193 are in the accommodation space 200 formed by the operation unit 70 on the back side of the front door 12.

  The accommodation space 200 has a depth dimension that can accommodate the housing 183 of the start operation device 181 and the housings 197 to 199 of the stop operation devices 191 to 193. The start operation device 181 and the stop operation devices 191 to 193 are disposed from the back side open portion 201 with respect to the accommodation space 200 and are fixed to the accommodation space 200. At this time, the housing 183 of the start operation device 181 and the housings 197 to 199 of the stop operation devices 191 to 193 are in contact with the back side of the operation unit 70. That is, the start operation device 181 and the respective stop operation devices 191 to 193 can be detached only from the back side open portion 201 in the accommodation space 200.

  The housing space 200 is provided with a plurality of bosses 202 (two in this embodiment). Each boss 202 is integrally formed with the front door 12 so as to extend from the back side of the operation unit 70 to the rear of the slot machine 10. The relay board 165 is attached to the accommodation space 200 by being screwed to these bosses 202. More specifically, the boss 202 has a screw hole 202a formed on the axis thereof, and the relay substrate 165 has a through-hole 211 penetrating in the thickness direction corresponding to the screw hole 202a. The relay board 165 is arranged so that each screw hole 202a and each through hole 211 are on the same line, and the screw 203 is screwed in this state.

  The relay board 165 has a size in the left-right direction that faces the start operation device 181 and all the stop operation devices 191 to 193. Further, the vertical dimension of the relay substrate 165 is substantially the same as the height dimension of the back-side opening 201 in the accommodation space 200. The relay board 165 is attached to the accommodation space 200 so that the plate surfaces 165a and 165b face in the front-rear direction, and the start operation device 181 and the stop operation devices 191 to 191 in the back-side opening 201 are provided. The region on the back side of 193 is closed. Thus, the start operation device 181 and the stop operation devices 191 to 193 are not exposed on the back surface of the front door 12.

  In addition, although the area | region which is not obstruct | occluded by the relay board | substrate 165 exists in the back side open part 201, the said area | region is comparatively narrow. Therefore, even if a finger or the like is inserted into the accommodation space 200 through the area, the start operation device 181, the stop operation devices 191 to 193, and the signal lines extending from the operation devices 181, 191 to 193 may be touched. , It has become difficult.

  The relay board 165 is a connector CN4 to which the signal line LN2 from the start operation board 182 is connected to the back side plate face 165b opposite to the front face plate face 165a facing the start operation device 181 and the stop operation devices 191 to 193. And connectors CN8 to which the signal lines LN4 from the stop operation boards 194 to 196 are connected. The connectors CN4 and CN8 are arranged between the through holes 211 so as to be aligned in the left-right direction.

  An insertion hole 212 is formed at one end side of the relay substrate 165 in the left-right direction and aligned with the connectors CN4, CN8 and the through hole 211 in the left-right direction. The signal line LN2 from the start operation board 182 and the signal lines LN4 from the stop operation boards 194 to 196 are drawn out to the back side plate surface 165b side of the relay board 165 through the insertion holes 212, and the corresponding connectors CN4 and CN8 Connected to.

  Further, the end side where the insertion hole 212 is formed in the back side plate surface 165b of the relay substrate 165 is connected to the connector CN11 to which the harness H is connected to the opposite end side, and the power line ELN2 from the power supply device 161 described later. Are connected in parallel in the vertical direction.

  A cover member 220 is coupled to the back side plate surface 165b of the relay substrate 165 so as to cover the connectors CN4 and CN8, the insertion hole 212, and the heads of the screws 203. Here, the cover member 220 will be described in detail.

  The cover member 220 is formed of a transparent synthetic resin material such as polycarbonate resin, and includes a horizontally long box-shaped accommodation portion 221 that is open on one side.

  The accommodating portion 221 is formed in a size that can accommodate the connectors CN4 and CN8, the head portion of the screw 203, and the insertion hole 212. Specifically, the space between the right wall portion 222a and the left wall portion 222b of the wall portion 222 that constitutes the housing portion 221 is the same as the head of the left screw 203 in FIG. 212, and the distance between the upper wall portion 222c and the lower wall portion 222d of the wall portion 222 is above and below the connector CN4, CN8, the head of the screw 203, and the insertion hole 212. It is larger than the direction dimension. The height of the wall portion 222 is such that the signal lines LN2 and LN4 do not contact the contact portion 221 with the connectors CN2 and CN6 of the signal lines LN2 and LN4 attached to the connectors CN4 and CN8 of the relay board 165, respectively. Even so, the signal lines LN2 and LN4 can be accommodated in the accommodating portion 221 without strongly pressing the signal lines LN2 and LN4 against the relay substrate 165. The cover member 220 is attached to the relay board 165 so as to accommodate the heads of the connectors CN4 and CN8 and the screw 203 by the accommodating portion 221 and to cover the insertion hole 212. In this attached state, the accommodating portion The open portion of 221 is blocked by the relay substrate 165.

  A seal coupling part 225 is integrally formed in the accommodating part 221 via a connecting part 228. A plurality of combinations of the seal coupling part 225 and the connecting part 228 are provided above and below the accommodating part 221 respectively. More specifically, the same number of combinations of the seal coupling part 225 and the connecting part 228 are provided on the upper side and the lower side of the accommodating part 221, respectively, and the upper and lower sides are spaced apart from each other by a predetermined interval in the left-right direction. Is provided.

  Each connecting portion 228 is formed to protrude upward from the upper wall portion 222c of the accommodating portion 221 and to protrude downward from the lower wall portion 222d. Each connecting portion 228 is formed in a thin plate shape, and each plate surface faces left or right. Seal coupling portions 225 are integrally formed at the ends of the connecting portions 228 opposite to the housing portion 221 side.

  Each seal coupling portion 225 has a cylindrical shape, and has a seal hole 226 whose axial direction is the height direction of the accommodating portion 221, that is, a direction substantially orthogonal to the relay substrate 165. One end of the seal coupling portion 225 is in contact with the back side plate surface 165b of the relay substrate 165, and the seal hole 226 is an end portion on the opposite side to the side in contact with the back side plate surface 165b from the middle position in the axial direction. The diameter has been expanded toward. A head portion of a sealing screw 229 described later is accommodated in the expanded diameter portion.

  A plurality of holes 213 are formed in the relay substrate 165 in a one-to-one correspondence with the sealing holes 226 of the respective seal coupling portions 225. The hole 213 penetrates the relay board 165 in the thickness direction, and in a state where the cover member 220 is attached to the relay board 165, each hole 213 and each sealing hole 226 are arranged on the same axis. And communicated. The cover member 220 is coupled to the relay substrate 165 by the sealing screw 229 being screwed into the communicating hole 213 and the sealing hole 226.

  As described above, a plurality of sealing coupling portions 225 are formed, but the coupling of the cover member 220 to the relay substrate 165 is accomplished without screwing the sealing screw 229 to all of them. For example, the above-mentioned coupling is achieved by screwing sealing screws 229 to the sealing coupling portions 225 and the holes 213 at the two upper and lower positions in the second position from the right in FIG.

  The sealing screw 229 is a so-called one-way screw (also referred to as a one-way screw). Once the sealing screw 229 is screwed into the sealing hole 226 and the hole 213, it is impossible to loosen the sealing screw 229 thereafter. It has become possible. Note that as a coupling means for coupling the relay substrate 165 to the cover member 220, a rupture screw whose head is fractured after screwing may be used in addition to a one-way screw, and a coupling pin whose head is buried after press-fitting is used. May be. Further, a coupling means such as a coupling pin may be provided integrally with the cover member 220. In short, it is sufficient that the relay board 165 is coupled to the cover member 220 by a coupling member in which it is difficult to remove the relay board 165 from the cover member 220.

  Since the cover member 220 is coupled to the relay board 165 by the sealing screw 229, each signal from the connectors CN2 and CN4 and the stop operation boards 194 to 196, which are connection portions of the signal line LN2 from the start operation board 182 The connectors CN6 and CN8, which are connecting portions of the line LN4, the insertion holes 212 formed in the relay board 165, and the heads of the screws 203 for fastening the relay board 165 cannot be exposed unless the cover member 220 is destroyed. Covered. Since the relay board 165 cannot be removed because the screw 203 is covered with the cover member 220, the start including the connectors CN1 and CN3 which are the connection portions of the signal line LN2 to the start operation board 182 is possible. Unless the cover member 220 is broken, the back side of the operation device 181 and the back side of each stop operation device 191 to 193 including the connectors CN5 and CN7 which are connection portions of the signal lines LN4 to the stop operation substrates 194 to 196 are exposed. It is covered so that it cannot.

  With the above configuration, it is difficult to remove the signal line LN2 and the signal line LN4. Further, since the back side of the start operation device 181 and the back side of each stop operation device 191 to 193 are covered, the signal line LN1 connecting the start detection sensor 71a and the start operation substrate 182 and the stop detection sensors 72a to 72a. Even if an attempt is made to remove the signal line LN3 that connects 74a to each of the stop operation boards 194 to 196, this is difficult. Even if the signal lines LN1 to LN4 are to be removed, the cover member 220 needs to be destroyed. Therefore, even if the signal lines LN1 to LN4 are illegally removed, the trace remains on the cover member 220, and it is possible to easily grasp that the signal lines LN1 to LN4 have been illegally removed by viewing the trace. it can.

  On the other hand, the sealed state by the cover member 220 can be released by cutting the connecting portion 228 corresponding to the sealed coupling portion 225 that has been coupled by the sealing screw 229 with a tool such as a nipper (part X in FIG. 13). ). As a result, the accommodating portion 221 of the cover member 220 can be separated from the relay board 165, and at the time of maintenance of the game hall, the signal lines LN2 and LN4 to the relay board 165 are shown in FIG. Connection portions (connectors CN2, CN4, CN6, CN8) and the like can be exposed on the back side of the front door 12. Further, by loosening the screws 203 and removing the relay board 165 from the back side of the front door 12, the start operation device 181 and the stop operation devices 191 to 193 are connected to the back surface of the front door 12, as shown in FIG. It can be exposed to the side. As a result, the signal line LN2 can be removed from the start operation board 182, and the signal line LN4 can be removed from each of the stop operation boards 194 to 196.

  Further, the connector CN11 to which the harness H in the relay board 165 is connected and the connector CN14 to which a power line ELN2 to be described later are connected are not housed in the housing portion of the cover member 220 and are formed on the back plate surface 165b of the relay board 165. Exposed. For this reason, the harness H can be removed from the relay board 165 without releasing the seal, and the connection between the relay board 165 and the main control board 131a via the harness H can be released. Further, the power supply line ELN2 can be removed from the relay board 165 without releasing the seal, and the connection between the relay board 165 and the power supply unit 161a via the power supply line ELN2 can be released.

  Returning to the description of FIG. 10, power is sent from the power supply unit 161 a of the power supply device 161 not only to the main control board 131 a but also to the relay board 165. In other words, 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 relay board 165. The CPU 151 is operated by power supplied from the power line ELN1, and various processes described later are executed. However, the power supplied from the power line ELN1 is not supplied to the RAM 153.

  The power supply line ELN2 has a connector CN13 connected to a connector CN14 (connector receiving portion) provided on the back side plate surface 165b of the relay board 165. The power sent to the relay substrate 165 by the power line ELN2 is sent to the RAM 153. Specifically, the harness H connecting the relay board 165 and the main control board 131a includes the power line ELN3. The power supplied from the power line ELN3 is supplied to a VBB terminal which is a backup power supply terminal provided in the CPU 151. Therefore, power from the power supply line ELN2 extending from the power supply device 161 is supplied to the RAM 153, and various data are stored and held in the RAM 153 by the power supply. Note that the power supplied from the power supply device 161 to the relay board 165 via the power supply line ELN2 is supplied to the VBB terminal as described above. This power supply is not a power supply for power supply interruption but a power supply for the slot machine 10. This is the power supplied to the RAM 153 when is in the ON state.

  The power supply device 161 is provided with a backup capacitor 161c. The backup capacitor 161c is connected to the power supply unit 161a of the power supply device 161. When the power of the slot machine 10 is ON, the backup capacitor 161c stores power. The backup capacitor 161c is connected to the power supply line ELN2 described above. Therefore, when the power of the slot machine 10 is OFF, the backup capacitor 161 c 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 161c. Incidentally, the capacity of the backup capacitor 161c is ensured to be relatively large, and 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-described configuration, a signal output device that outputs a start detection signal and a stop detection signal is connected to the main control board 131a, and an illegal act is attempted to generate a BB prize by outputting each signal. Can be suppressed.

  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 play a game without actually operating the start lever 71 and the stop switches 72 to 74. 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.

  The output of the start detection signal and the stop detection signal from the signal output device in such a fraudulent act (an act of unjustly gambling if the game hall is intentionally performed) is performed by connecting the relay board 165 and the main control board 131a. The harness H to be connected is removed, and the harness extending from the signal output device is connected to the connector CN12 on the main control board 131a side to which the connector CN10 of the harness H is connected. Further, the connector CN9 of the harness H is removed from the relay board 165, and the connector CN9 is connected to the signal output device.

  On the other hand, as described above, power to the RAM 153 is supplied via the relay board 165. That is, power is supplied to the RAM 153 via the power supply line ELN3 included in the harness H. Therefore, when the harness H is 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 harness H is 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 end side of the harness H. That is, the signal line LN2 that connects the start operation board 182 and the relay board 165 and the signal line LN4 that connects the stop operation boards 194 to 196 and the relay board 165 are removed, and instead, the signal output device is connected to the relay board 165. The act of connecting is assumed. Further, the signal line LN1 that connects the start detection sensor 71a and the start operation board 182 and the signal line LN3 that connects each stop detection sensor 72a to 74a and each stop operation board 194 to 196 are removed, and instead, a signal output device. The act of connecting

  On the other hand, as described above, the relay board 165 is attached on the back side of the front door 12 so that the start operating device 181 and the stop operating devices 191 to 193 are not exposed, and the signal lines LN2 and LN4 and the relay board. The cover member 220 is coupled to the relay substrate 165 so that the connection portion with the 165 and the screws 203 are not exposed. Further, when the connection between the relay substrate 165 and the cover member 220 is released, the trace remains. Therefore, it is difficult to replace the main control board 131a with the signal output device at the terminal side of the harness H, and even if the replacement is performed, the trace can be left. For this reason, it is possible to suppress the act of changing to the signal output device on the terminal side.

  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 roughly 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. 15 is a flowchart showing an example of NMI interrupt processing. 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 in 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. 16 is a flowchart of timer interrupt processing periodically executed by the main control device 131, and 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 detailed description is omitted, it is confirmed whether or not a power failure signal is output even under an infinite loop, and when the power failure signal is not output, the processing shifts to a main process described later.

  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. 18 is a flowchart showing a main process in the main controller 131 executed after the power is turned on. The main processing is executed when 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. Thereafter, various settings for the register group in the CPU 151, the I / O device, and the like are 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 the ON operation is not performed, the process is terminated as it is. 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, and 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. 22 is a lottery table 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 larger as the lottery table has a higher setting value, and the point value PV is set 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 by 1 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. 22 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 the visible range from each display window 31L, 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. 23 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. 24, 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. 23 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 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 in 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 subsequent step S902, 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 devices 191 to 193. 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 devices 191 to 193 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 change 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. 24). 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. 23) 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 slip table shown in FIG. 23, the “replay” symbol of the number 11 stops on the lower line instead of the “watermelon” symbol of the number 9. 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 slide table set in the slide table setting process, the slide table in which 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. 23 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.

  If 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 of 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, display part change processing for adding 1 to the number of acquired number display part 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, first, in step S1302, it is determined 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. On the other hand, when the combination of BB symbols on the current effective line stops, 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 or 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 S1309 is executed. 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 the 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. To do.

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

  The relay board 165 that relays the start detection signal from the start operation device 181 and the stop detection signals from the stop operation devices 191 to 193 relays the power from the power supply device 161 to the RAM 153. Further, a harness H is provided between the relay board 165 and the main control board 131a so as to connect them, and each signal line of the start detection signal and the stop detection signal relayed by the harness H on the relay board 165 is provided. And the power supply line ELN3 of the power source relayed by the relay board 165 are collectively connected to the relay board 165 and the main control board 131a. Accordingly, when the harness H is removed in order to output an illegal signal from the signal output device to the main control device 131, the power is not supplied to the RAM 153.

  In particular, in the configuration of the present embodiment, by providing the cover member 220 as the trace means, the signal lines LN1 to LN4 on the terminal side of the signal path with respect to the main controller 131 are removed from the main controller 131. Instead, it is not possible to easily connect a signal output device. Therefore, it is considered that a person trying to perform an illegal act using the signal output device replaces the signal output device with respect to the easily removable harness H. When the harness H is removed, the power is not supplied to the RAM 153 as described above. .

  With the above configuration, even if a signal output device is connected and the winning information (BB winning flag) or BB gaming status information (BB setting flag) of the BB role is stored in the RAM 153, the signal output device is removed and the normal signal When switching to the line, the supply of power to the RAM 153 is stopped, and the stored winning information of the BB combination and BB gaming state information are erased. Therefore, it is possible to suppress the act of connecting the signal output device 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.

  In the present embodiment, a plurality of signals (start detection signal and stop detection signal) among signals necessary for variable display of symbols on the reel unit 41 are relayed by the relay board 165, and these signals are relayed. The signal lines are grouped as a harness H. Therefore, a person who intends to perform an illegal act using the signal output device outputs a signal to the harness H that is easier to work than when the signal lines LN1 to LN4 on the terminal side of the relay board 165 are individually disconnected. It is considered that the device is replaced, and when the harness H is removed, the power is not supplied to the RAM 153 as described above.

  The cover member 220 was attached so that the connection part of the signal lines LN <b> 2 and LN <b> 4 on the relay substrate 165 was accommodated in the accommodation part 221. For this reason, even if the signal lines LN2 and LN4 are removed from the relay board 165 and the signal output device is connected to the relay board 165 instead of the signal lines LN2 and LN4, this can be done unless the cover member 220 is removed from the relay board 165. There is no such thing. Therefore, removal of the signal lines LN2 and LN4 from the relay board 165 at the time of fraud using the signal output device can be suppressed.

  The cover member 220 is required to be destroyed when the connection between the relay substrate 165 and the cover member 220 is released. Therefore, when the signal output device is connected after the signal lines LN2 and LN4 are removed, the trace remains, so that it can be easily confirmed, and further, an illegal act using the signal output device is attempted. The person who is present can be reluctant to replace the signal output device with respect to the signal lines LN2 and LN4.

  The relay substrate 165 is provided so as to close the back side open portion 201 of the accommodation space 200 in which the back side of the start operation device 181 and the back side of each of the stop operation devices 191 to 193 are accommodated. Further, the head of the screw 203 that fixes the relay substrate 165 is covered with the cover member 220. This makes it difficult to expose the back side of the start operation device 181 and the back side of each stop operation device 191 to 193, and the signal line LN2 and the signal line LN4 from the start operation device 181 and the stop operation devices 191 to 193. Even if the signal output device is connected to the signal line LN2 or the signal line LN4 instead of the start operation device 181 and the stop operation devices 191 to 193, it cannot be easily performed.

  Further, as described above, the cover member 220 has a function of accommodating the connection portions of the signal lines LN2 and LN4 in the relay substrate 165. That is, since the replacement of the signal output device on the terminal side with respect to the relay substrate 165 is suppressed by the single cover member 220, the above-described effects can be achieved while simplifying the configuration.

  The operation unit 70 is provided so as to protrude to the front of the slot machine 10 in order to improve the operability of the start lever 71 and the stop switches 72 to 74. The operation space 70 is provided so as to protrude forward of the slot machine 10 as described above, whereby the accommodation space 200 is formed. That is, in this embodiment, the above-described effect can be achieved while effectively using the configuration of the operation unit 70.

  Since the cover member 220 is formed of a synthetic resin material having transparency, the connection portions of the signal lines LN2 and LN4 on the back side plate surface 165b of the relay substrate 165 can be visually recognized without removing the cover member 220 from the relay substrate 165. .

  Since the insertion hole 212 is formed in the relay board 165, when the signal lines LN2 and LN4 are connected to the back side plate surface 165b of the relay board 165, the signal line LN2 that connects the start operating device 181 and the relay board 165, and each stop There is no need to wire the signal line LN4 connecting the operation devices 191 to 193 and the relay board 165 so as to wrap around the relay board 165. Therefore, the signal lines LN2 and LN4 can be made relatively short. Further, since the cover member 220 is attached to the relay board 165 so as to cover the insertion hole 212, the signal lines LN2 and LN4 are extracted from the start operation device 181 and the respective stop operation devices 191 to 193 through the insertion hole 212, and the signals The act of connecting the lines LN2 and LN4 to the signal output device can be suppressed.

  In the cover member 220, the accommodating portion 221 and the seal coupling portion 225 are connected by a thin plate-like connecting portion 228. Thereby, at the time of maintenance of the relay substrate 165, the coupling between the relay substrate 165 and the cover member 220 can be released relatively easily by cutting the connecting portion 228. Therefore, it is possible to improve the maintainability.

  Further, the cover member 220 is provided with a plurality of combinations of the seal coupling part 225 and the connecting part 228. The cover member 220 is coupled to the relay substrate 165 so as not to be separated by setting a part of the plurality of seal coupling portions 225 in a coupled state. As a result, even if the connecting portion 228 corresponding to the seal coupling portion 225 in the coupled state is cut for maintenance, the cover member 220 is again connected to the relay board by bringing another seal coupling portion 225 into the coupled state. 165. Therefore, it is possible to improve the convenience during maintenance while exhibiting the effect of suppressing the replacement of the signal output device on the terminal side with respect to the relay board 165.

  The connector CN9 of the harness H is connected to the connector CN11 of the back side plate surface 165b of the relay board 165 so that the connection portion is not accommodated in the cover member 220. Thereby, in the structure which suppressed removal of each signal wire | line LN2, LN4 at the time of fraud using a signal output device, the removal of the harness H from the relay board | substrate 165 can be easily performed at the time of a maintenance. Further, with this configuration, it is considered that a person who intends to perform an illegal act using the signal output device replaces the signal output device with respect to the harness H that is easy to remove. When removed, the power is not supplied to the RAM 153 as described above.

  The power from the backup capacitor 161c is also supplied through the power line ELN3 of the harness H. As a result, 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 the BB gaming status information (BB setting flag) of the BB role are stored in the RAM 153. Even when the signal output device is removed and the harness H is connected, the stored winning combination information and BB gaming state information of the BB combination are deleted. Therefore, this act can be suppressed.

(Second Embodiment)
In the present embodiment, the configuration relating to the relay board is different from that of the first embodiment. Therefore, the configuration according to the following will be described in detail. In the following description, differences from the first embodiment will be described, and description of the same configuration will be basically omitted. 30A is an enlarged rear view showing the periphery of the relay board 165 on the rear side of the front door 12, and FIG. 30B is a rear view showing a state in which the cover member 260 is removed from the state of FIG. 30C is a rear view showing a state in which the relay board 165 is removed from the state of FIG. 30B, and FIG. 31 illustrates the configuration of the cover member 260 in the vicinity of the line CC in FIG. It is explanatory drawing for.

  Similar to the first embodiment, a relay board 165 is provided, and the relay board 165 closes the back side opening 201 in the accommodation space 200 with screws 203 on the back side of the front door 12. Screwed. Further, the connector CN11 for connecting the main control board 131a to the relay board 165 via the harness H and the power supply unit 161a are connected to the relay board 165 via the power line ELN2 on the back side plate surface 165b of the relay board 165. A connector CN14 is provided.

  However, in the present embodiment, unlike the first embodiment, the connector CN4 for connecting the start operation board 182 to the relay board 165 via the signal line LN2 and the stop operation boards 194 to 196 are provided. A connector CN8 for connecting to the relay substrate 165 via the signal line LN4 is disposed on the front side plate surface 165a instead of the back side plate surface 165b of the relay substrate 165. A connector CN2 of the signal line LN2 is attached to the connector CN4, and a connector CN6 of the signal line LN4 is attached to the connector CN8. Therefore, the signal lines LN2 and LN4 are accommodated in the accommodation space 200.

  In addition, although the area | region which is not obstruct | occluded by the relay board | substrate 165 exists in the back side open part 201, the said area | region is comparatively narrow. For this reason, in a state where the relay substrate 165 is attached to the back side of the front door 12, a finger or the like is inserted into the accommodation space 200 through the area, and the start operation device 181 and the stop operation devices 191 to 193, Even if it tries to touch the signal lines LN2 and LN4 connected to these operating devices 181, 191 to 193, it is difficult to do so. Further, it is difficult to touch the connectors CN2 and CN4 of the relay board 165 and the signal lines LN2 and LN4 connected to the connectors CN2 and CN4.

  A plurality of cover members 260 are coupled to the back side plate surface 165 b of the relay substrate 165 so as to cover the heads of the screws 203. Here, the cover member 260 will be described in detail.

  The cover member 260 is formed of a transparent synthetic resin material such as polycarbonate resin, and includes a box-shaped storage portion 261 that is open on one side. The accommodating part 261 is formed in a size that can accommodate the head of one screw 203. The cover member 260 is attached to the relay substrate 165 so that the head portion of the screw 203 is accommodated by the accommodating portion 261. In this attached state, the open portion of the accommodating portion 261 is blocked by the relay substrate 165. Yes.

  A seal coupling portion 265 is integrally formed with the accommodating portion 261 via a connecting portion 268. One combination of the seal coupling portion 265 and the connecting portion 268 is provided on the top, bottom, left, and right of the housing portion 261.

  Each connecting portion 268 is formed to protrude outward from each wall portion 262 of the accommodating portion 261. Each connecting portion 268 is formed in a thin plate shape, and each plate surface faces upward or downward, leftward or rightward. That is, each connecting portion 268 is provided so as to stand rearward with respect to the relay substrate 165. Seal coupling portions 265 are integrally formed at the ends of the connecting portions 268 opposite to the housing portion 261 side.

  Each sealing coupling portion 265 has a cylindrical shape, and has a sealing hole 266 whose axial direction is the height direction of the accommodating portion 261, that is, a direction substantially orthogonal to the relay substrate 165. One end of the seal coupling portion 265 is in contact with the back side plate surface 165b of the relay substrate 165, and the seal hole 266 is an end portion on the opposite side from the side in contact with the back side plate surface 165b from the middle position in the axial direction. The diameter has been expanded toward. The head of a sealing screw 269, which will be described later, is accommodated in the expanded diameter portion.

  A plurality of holes 255 are formed in the relay substrate 165 in a one-to-one correspondence with the sealing holes 266 of the seal coupling portions 265. The hole portion 255 penetrates the relay substrate 165 in the thickness direction, and in a state where the cover member 260 is attached to the relay substrate 165, each hole portion 255 and each sealing hole 266 are arranged on the same axis. And communicated. The cover member 260 is coupled to the relay substrate 165 by the sealing screw 269 being screwed into the hole 255 and the sealing hole 266 that are communicated with each other.

  As described above, a plurality of sealing coupling portions 265 are formed, but the coupling of the cover member 260 to the relay board 165 is achieved without screwing the sealing screw 269 to all of them. For example, the above-described coupling is achieved by screwing sealing screws 269 to the left and right sealing coupling portions 265 and the hole portions 255, respectively.

  As with the sealing screw 229 in the first embodiment, the sealing screw 269 is configured so that once it is screwed into the sealing hole 266 and the hole portion 255, it is impossible to loosen the sealing screw 269 thereafter. Yes.

  Since each cover member 260 is coupled to the relay substrate 165 by the sealing screw 269, the head of each screw 203 is covered so that it cannot be exposed unless the cover member 220 is destroyed. As described above, the relay substrate 165 is attached so as to block the back side open portion 201 of the accommodation space 200, and the signal lines LN2 and LN4 are accommodated in the accommodation space 200. Therefore, it is difficult to remove the signal line LN2 from the relay board 165 and the start operation board 182 or to remove the signal line LN4 from the relay board 165 and the stop operation boards 194 to 196. It has become a thing. Further, the signal line LN1 may be removed from the start detection sensor 71a and the start operation board 182, or the signal line LN3 may be removed from the stop detection sensors 72a to 74a and the stop operation boards 194 to 196. , It has become difficult. Further, in order to remove the signal lines LN1 to LN4, it is necessary to destroy the cover member 260. Therefore, when the signal lines LN1 to LN4 are illegally removed, the trace remains on the cover member 260, and it is easy to grasp that the signal lines LN1 to LN4 have been illegally removed by viewing the trace. Can do.

  On the other hand, the sealed state by the cover member 260 can be released by cutting the connecting portion 268 corresponding to the sealed coupling portion 265 that has been coupled by the sealing screw 269 with a tool such as a nipper. Thereby, the accommodating portion 261 of the cover member 260 can be separated from the relay board 165, and when the maintenance of the game hall is performed, the cover member 260 is removed from the relay board 165, as shown in FIG. Furthermore, the screw 203 can be exposed to the back side of the front door 12. Further, by loosening the screws 203 and removing the relay substrate 165 from the back side of the front door 12, the start operation device 181 and the stop operation devices 191 to 193 are moved to the back side of the front door 12, as shown in FIG. It becomes possible to expose to. As a result, the signal line LN2 can be removed from the start operation board 182 and the relay board 165, and the signal line LN4 can be removed from the stop operation boards 194 to 196 and the relay board 165.

  Further, since the connectors CN11 and CN14 provided on the back side plate surface 165b of the relay board 165 are exposed on the back side of the front door 12, the harness H can be removed from the connector CN11 of the relay board 165 without releasing the seal. The connector CN9 can be removed, and the connector CN13 of the power supply line ELN2 can be removed from the connector CN14 of the relay board 165.

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

  The relay substrate 165 is provided so as to close the back side open portion 201 of the accommodation space 200 in which the back side of the start operation device 181 and the back side of each of the stop operation devices 191 to 193 are accommodated. Further, the signal line LN2 from the start operation device 181 and the signal lines from the stop operation devices 191 to 193 are provided on the front plate surface 165a facing the start operation device 181 and the stop operation devices 191 to 193 on the relay board 165. LN4 was connected. Further, a cover member 260 that covers the head of the screw 203 for fixing the relay substrate 165 to the front door 12 is provided, and the cover member 260 is coupled to the relay substrate 165 so as not to be separated. As a result, it becomes difficult to expose the signal lines LN2 and LN4, the back side of the start operation device 181 and the back side of each stop operation device 191 to 193, and the relay board 165, the start operation device 181 or the stop operation Even if the signal line LN2 or the signal line LN4 is removed from the devices 191 to 193 and the signal output device is connected to the relay substrate 165 or the signal lines LN2 and LN4, it cannot be easily performed. That is, even if the signal lines LN1 to LN4 on the end side of the signal path with respect to the main control device 131 are used as a reference and the signal output device is connected instead, it cannot be easily performed. ing. Therefore, it is considered that a person trying to perform an illegal act using the signal output device replaces the signal output device with respect to the easily removable harness H. When the harness H is removed, the power is not supplied to the RAM 153 as described above. .

  In particular, in this configuration, by providing the cover member 260 so as to accommodate the head of the screw 203, the act of removing the signal lines LN1 to LN4 and connecting the signal output device instead is suppressed. Therefore, compared with the configuration in which the cover member 260 is provided corresponding to each of the signal lines LN1 to LN4, the above effects can be achieved while simplifying the configuration.

  The second embodiment has the same or similar configuration as the characteristic configuration in the first embodiment, and the effect based on this configuration is the same in the second embodiment. To play.

(Third embodiment)
In the present embodiment, the configuration relating to the supply of power to the RAM 153 is different from those in the above embodiments. 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. 32 is a block circuit diagram in the present embodiment.

  As shown in FIG. 32, in the present embodiment, as in the first embodiment, the main control device 131, the power supply device 161, the relay board 165, the start operation device 181 and the stop operation devices 191 to 193 are provided. Is provided. The relay board 165 is connected to the start operation board 182 of the start operation apparatus 181 via the signal line LN2, and is connected to the stop operation boards 194 to 196 of the stop operation apparatuses 191 to 193 via the signal line LN4. ing. Although a detailed description is omitted, the installation mode of the relay board 165 with respect to the front door 12 and the connection mode of the signal lines LN2 and LN4 are the same as those in the first embodiment, and further to the relay board 165 A cover member is provided in the same manner as in the first embodiment.

  The relay board 165 is connected to the main control board 131a of the main control device 131 via the harness H1. The harness H1 has connectors CN31 and CN32 at both ends thereof, and these connectors CN31 and CN32 are attached to a connector CN33 included in the relay board 165 and a connector CN34 included in the main control board 131a (corresponding to input means). Yes. That is, the harness H1 is detachably attached to the relay board 165 and the main control board 131a.

  The power supply unit 161a of the power supply device 161 is connected to the main control board 131a via the power supply line ELN1, and power is supplied from the power supply part 161a to the CPU 151 of the main control board 131a via the power supply line ELN1. However, the power supplied to the CPU 151 is not supplied to the RAM 153.

  In the present embodiment, unlike the first embodiment, the power supply unit 161a is not connected to the relay substrate 165, and power is not supplied from the power supply unit 161a to the relay substrate 165. The harness H1 that connects the main control board 131a and the relay board 165 includes a connection confirmation signal line LLN1. A relay circuit EC is provided on the relay board 165, and the connection confirmation signal line LLN1 is grounded in the relay board 165 via the relay circuit EC. A ground potential (L level) is transmitted from the relay board 165 to the main control board 131a as a connection information signal via the connection confirmation signal line LLN1. Here, the connection information signal is also referred to as a connection confirmation signal for confirming the connection between the main control board 131a and the relay board 165.

  The power supply line ELN1 for supplying power from the power supply unit 161a to the main control board 131a is branched in the main control board 131a. When power is supplied from the power supply unit 161a to the main control board 131a, power is supplied from the power supply unit 161a to the CPU 151 of the main control board 131a, and a backup power generation circuit 281 mounted on the main control board 131a. In addition, power is supplied from the power supply unit 161 a to the VBB terminal which is a backup power supply terminal of the CPU 151 via the switching circuit 282. The switching circuit 282 includes a MOSFET 282a and a pull-up resistor 282b. The MOSFET 282a is of a type in which current does not flow between the source and drain when the input voltage of the gate terminal is at L level, and current does not flow between the source and drain when it is at H level. The gate terminal of the MOSFET 282a is connected to the backup power supply generation circuit 281 through the pull-up resistor 282b, and is connected to the connection confirmation signal line LLN1 of the harness H1.

  With the above-described configuration, a signal output device that outputs a start detection signal and a stop detection signal is connected to the main control board 131a, and an illegal act is attempted to generate a BB prize by outputting each signal. Can be suppressed.

  That is, in the present embodiment, as described above, since the connection confirmation signal line LLN1 included in the harness H1 is grounded in the relay board 165 via the relay circuit EC, the harness H1 is connected to the main control board 131a. In the state of being attached to the relay board 165, the L level is input to the main control board 131a as a connection confirmation signal. As a result, the input voltage at the gate terminal of the MOSFET 282a becomes L level, current flows between the source and drain of the MOSFET 282a, and power is supplied to the VBB terminal. On the other hand, when the harness H1 is detached from the main control board 131a or the relay board 165, a 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 282a becomes H level because the gate terminal is pulled up to the output voltage of the backup power generation circuit 281. Then, no current flows between the source and drain of the MOSFET 282a, and power is not supplied to the VBB terminal.

  That is, when the harness H1 is detached from the main control board 131a or the relay board 165 and the signal output device is connected to the main control board 131a, the connection confirmation signal is not input to the main control board 131a, and the power supply to the RAM 153 is performed. Is stopped by MOSFET 282a. 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 interrupted when the signal output device is disconnected and the harness H1 is connected. Supply is interrupted by MOSFET 282a. 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 harness H1. That is, the signal line LN2 that connects the start operation board 182 and the relay board 165 and the signal lines LN4 that connect the stop operation boards 194 to 196 and the relay board 165 are removed, and the signal output device is connected to the relay board 165. As a result, an action of connecting the signal output device to the main control board 131a via the relay board 165 is assumed. Further, the signal line LN1 that connects the start detection sensor 71a and the start operation board 182 and the signal lines LN3 that connect the stop detection sensors 72a to 74a and the stop operation boards 194 to 196 are removed, and the signal output device is removed. It is assumed that the signal output device is connected to the main control board 131a via the start operation board 182, the stop operation boards 194 to 196, and the relay board 165 by connecting to the start operation board 182 and the stop operation boards 194 to 196. Is done. On the other hand, in the present embodiment, as in the first embodiment, the removal of the signal lines LN1 to LN4 is suppressed at the terminal side of the harness H1 with respect to the main control board 131a. When the signal lines LN1 to LN4 are removed, a trace remains. For this reason, it is possible to suppress the act of changing to the signal output device on the terminal side.

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

  The main control board 131a includes a switching circuit 282 that includes the connection confirmation signal line LLN1 in the harness H1 attached to the main control board 131a and the relay board 165, and controls the power supply to the RAM 153 according to the connection confirmation signal. It was. Therefore, when the harness H1 is removed from the main control board 131a or the relay board 165, a connection confirmation signal is not transmitted to the main control board 131a, and the power supply to the RAM 153 is stopped by the MOSFET 282a. Therefore, the harness H1 is removed, and a signal output device that outputs the start detection signal, the stop detection signal, and the medal detection signal is connected to the main control board 131a, and the winning information (BB winning flag) of the BB role and BB game are stored in the RAM 153 Even if the state information (BB setting 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 information of the BB role and the BB gaming state are stored. Information is erased. Therefore, it is possible to suppress the act of connecting the signal output device to the main control board 131a 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 harness H1 including the connection confirmation signal line LLN1 that transmits a connection confirmation signal is easily 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 relay board 165, 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. Accordingly, it is not necessary to provide a circuit for generating a connection confirmation signal on the relay board 165, and the configuration for outputting the connection confirmation signal can be simplified.

  The power supply from the backup power generation circuit 281 is also controlled by the switching circuit 282. Thereby, the signal output device is connected to the main control board 131a in the state where the power of the slot machine 10 is cut off, and the winning information (BB winning flag) of the BB role and the BB gaming state information (BB setting flag) are stored in the RAM 153. Even if the information is stored, when the signal output device is removed and the signal line LN2 and the harness H1 are connected, the stored winning information of the BB combination and the BB gaming state information are deleted. Therefore, this act can be suppressed.

  A power supply line ELN1 for supplying power from the power supply unit 161a of the power supply device 161 to the main control board 131a is branched in the main control board 131a, and is transferred from the power supply unit 161a to the RAM 153 via the backup power generation circuit 281 and the switching circuit 282. The power was supplied. 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 281 and the switching circuit 282 are provided by being 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.

  The third embodiment has the same or similar configuration as the characteristic configuration in the first embodiment, and the effects based on this configuration are the same in the third embodiment. To play.

(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. 33 shows a modification of the first embodiment. In such a modification, unlike the first embodiment, the connector CN1 on the start operation board 182 side of the signal line LN2 connecting the start operation board 182 and the relay board 165 is exposed to the outside of the housing 183 of the start operation device 181. Further, the connector CN5 on the stop operation board 194 to 196 side of the signal line LN4 connecting the stop operation boards 194 to 196 and the relay board 165 is exposed outside the housings 197 to 199 of the stop operation devices 191 to 193. Yes. In this case, the signal lines LN2 and LN4 can be disconnected from the start operation board 182 and the stop operation boards 194 to 196 without disassembling the housing 183 of the start operation apparatus 181 and the housings 197 to 199 of the stop operation apparatuses 191 to 193. Therefore, the workability at the time of maintenance can be improved.

  Even in the above-described configuration, the relay board 165 is provided so as to block the back side open part 201 of the accommodation space 200 formed by the operation unit 70, and the cover member 220 is separated on the back side of the relay board 165. It is bound impossible. Therefore, even if it is attempted to connect the signal output device to the main control board 131a by removing the signal lines LN1 to LN4 located on the end side of the signal path from the relay board 165 with respect to the main control apparatus 131, this cannot be easily performed. It is like that. Therefore, it is considered that a person trying to perform an illegal act using the signal output device replaces the signal output device with respect to the easily removable harness H. When the harness H is removed, the power is not supplied to the RAM 153 as described above. .

  The configuration may be applied to the second embodiment.

  (2) FIG. 34 shows a modification of the third embodiment. In such a modification, a switching circuit 285 different from that of the third embodiment is provided on the main control board 131a, and the switching circuit 285 includes a MOSFET 285a and a pull-down resistor 285b. MOSFET 285a is of a type in which current flows between the source and drain when the input potential of the gate terminal is at the H level, and no current flows between source and drain when the input potential is at the L level. The gate terminal of the MOSFET 285a is grounded via a pull-down resistor 285b and is connected to the connection confirmation signal line LLN1 of the harness H1. Further, in the relay board 165 to which the harness H1 is connected, the connector CN13 of the power supply line ELN4 connected to the power supply unit 161a of the power supply device 161 is attached to the connector CN14. The signal line LLN1 for connection confirmation of the harness H1 is connected to the power supply line ELN4 through the relay circuit EC1 inside the relay board 165. The power supply unit 161a outputs an H level (5V) as a connection confirmation signal to the main control board 131a.

  In this case, when the harness H1 is connected, the input voltage at the gate terminal of the MOSFET 285a is at the H level, current flows between the source and drain of the MOSFET 285a, and power is supplied to the VBB terminal. On the other hand, when the harness H1 is disconnected, the connection confirmation signal is not input, and the input voltage of the gate terminal of the MOSFET 285a becomes L level by the pull-down resistor 285b. As a result, no current flows between the source and drain of the MOSFET 285a, and power is not supplied to the VBB terminal.

  Even in such a configuration, when the harness H is removed, the power supply to the RAM 153 is stopped by the switching circuit 285 as the connection confirmation signal (H level) is not transmitted. Therefore, as in the third embodiment, the signal output device is connected to the main control device 131, and the winning information (BB winning flag) and the BB gaming status information (BB setting flag) of the BB role are stored in the RAM 153. Can be suppressed.

  (3) In the first and second embodiments, the power from the power supply device 161 to the RAM 153 is first input to the main control device 131 and then relayed by the relay board 165 and then supplied to the RAM 153. May be. Specifically, two power lines are provided in the harness H together with a signal line for a start detection signal and a signal line for a stop detection signal (hereinafter, one of the power lines is referred to as a first power line and the other is a second power line). Called a line). A part of the power supplied from the power line ELN1 to the main controller 131 is input to the relay board 165 through the first power line, and the power is returned to the main controller 131 through the second power line. The power returned by the second power line is input to the VBB terminal. In this case, the power is not supplied to the RAM 153 when the harness H is removed as in the first and second embodiments.

  (4) In the second embodiment, the signal line LN2 from the start operating device 181 is attached by attaching the relay board 165 so as to close the back side open part 201 of the accommodation space 200 formed by the operation part 70. Although the connection location on the relay board 165 and the connection location on the relay board 165 of the signal line LN4 from the stop operation devices 191 to 193 are not exposed on the back side of the front door 12, this may be changed. For example, a dedicated housing recess for housing the connection locations of the signal lines LN2 and LN4 on the relay board 165 may be formed on the back surface of the front door 12.

  (5) In each of the above embodiments, the medal detection signal from the selector 84 may be relayed by the relay board 165. In this case, a signal line for a medal detection signal is provided in the harness H, and the medal detection signal relayed by the relay board 165 is output to the main control board 131a via the harness H. In addition, by applying the installation mode of the relay board 165 and the connection mode of the signal line to the relay board 165 in each of the above embodiments, and further providing a trace means such as a cover member, an illegal act using the signal output device It is considered that the person who wants to perform the replacement of the signal output device with respect to the easily removable harness H. In addition, for the person who intends to perform the illegal act, all of the start detection signal, the stop detection signal, and the medal detection signal from the signal output device can be output simply by changing the signal output device to the harness H. Therefore, it is considered that the signal output device is replaced with respect to the harness H from this point. On the other hand, when the harness H is removed, the power is not supplied to the RAM 153 as described above, so that an illegal act using the signal output device can be suppressed.

  (6) In the first embodiment, the relay board 165 is attached to the back side of the front door 12, but it may be attached to the housing 11 instead. However, in this configuration, the relay substrate 165 does not face the start operation device 181 and the stop operation devices 191 to 193 on the back side of the front door 12. That is, the back side of the start operation device 181 and the stop operation devices 191 to 193 are exposed on the back side of the front door 12. Therefore, it is preferable to provide trace means for the start operation device 181 and the stop operation devices 191 to 193. Specifically, a plate portion is disposed on the back side of the front door 12. In this case, the dimension in the left-right direction of the plate portion is set to a size that faces all of the start operation device 181 and each of the stop operation devices 191 to 193, and the size in the vertical direction is the height dimension of the back side opening portion 201 in the accommodation space 200. And approximately the same. Then, the plate portion is fixed to the front door 12 with screws, the cover member is attached to the plate portion so as to accommodate the head portion of the screw, and the cover member is coupled to the plate portion inseparably. Thereby, even when the relay board 165 is attached to the housing 11, the signal line LN1 is removed from the start detection sensor 71a and the start operation board 182, and each stop detection sensor 72a to 74a and each stop operation board 194 to 196 is removed. The signal line LN3 can be removed from the start operation board 182, and the signal line LN4 can be prevented from being removed from the stop operation boards 194 to 196.

  (7) You may change the structure of the trace means in each said embodiment. For example, instead of providing the cover members 220 and 260 on the relay board 165, a seal seal may be attached so as to straddle the connectors CN2 and CN6 of the signal lines LN2 and LN4 and the connectors CN4 and CN8 of the relay board 165. When the seal seal is once affixed and then peeled off, the adhesive is peeled off from the seal label and cannot be reapplied. When the seal seal is peeled off, the trace remains. By sticking the seal, it is possible to confirm whether or not the connectors CN2 and CN6 of the signal lines LN2 and LN4 are removed from the connectors CN4 and CN8 of the relay board 165. Further, a seal seal may be attached so as to straddle the screw 203 and the relay substrate 165. In this case, it can be confirmed whether or not the relay board 165 is removed from the front door 12.

  (8) In each of the above embodiments, the signal line LN2 from the start operation board 182 and the signal line LN4 from the stop operation boards 194 to 196 are connected to the relay board 165 via the connectors CN2, CN4, CN6, CN8. The connection is detachable, but this may be changed. For example, the signal lines LN2 and LN4 may be connected in a state where it is difficult to attach and detach by fixing them with solder or the like. Even in this case, the signal lines LN2 and LN4 can be removed from the relay board 165 by applying the installation mode of the relay board 165 in each of the above embodiments and further providing a trace means such as a cover member. Can be difficult.

  (9) In each of the above embodiments, the relay board 165 is fixed by the screws 203, but the method for fixing the relay board 165 is arbitrary. However, it is preferable to attach the relay substrate 165 in a detachable state so that the signal lines LN2 and LN4 can be removed during maintenance or the like. As a configuration for attaching the relay substrate 165 in a detachable state without using a screw, a configuration in which an engagement portion or the like is provided on the housing 11 or the front door 12 and the relay substrate 165 is engaged with the engagement portion can be considered. . Even in such a configuration, by providing the trace means for the engaging portion, it is possible to achieve the same effects as the effects in the above embodiments.

  (10) In each of the above embodiments, the cover members 220 and 260 are made of a synthetic resin material having transparency, but may be made of a non-transparent material. When the cover members 220 and 260 are formed of a non-transparent material, the inside of the cover members 220 and 260 cannot be visually recognized. For this reason, it is good to form the through-hole etc. which can visually recognize the inside of cover member 220,260.

  (11) In the first embodiment, the cover member 220 is provided so as to cover the connection portions of the signal lines LN2 and LN4, the heads of the screws 203, and the insertion holes 212 on the back side plate surface 165b of the relay substrate 165. However, it is not limited to this. For example, the insertion hole 212 may not be covered with the cover member 220. Moreover, it is good also as a structure which provides a cover member for every covering object instead of covering all with one cover member 220, respectively. For example, a cover member is provided for the connection portion of the signal lines LN2 and LN4, and a cover member is provided for the head of the screw 203.

  (12) In the first embodiment, the insertion portion is formed by the insertion hole 212 in the relay substrate 165. However, it may be formed by recessing a part of one side of the relay substrate 165 inward. In short, any configuration is possible as long as the signal lines LN2 and LN4 can be drawn out to the back plate surface 165b side. Even when a part of one side of the relay board 165 is recessed inward to form the insertion part, the signal line is connected via the insertion part by connecting the cover member 220 to the relay board 165 so as to cover the insertion part. LN2 and LN4 can be extracted from the start operating device 181 and the stop operating devices 191 to 193, and the act of connecting the signal lines LN2 and LN4 to the signal output device can be suppressed.

  (13) In the above embodiments, when the harnesses H and H1 are removed, the supply of power to the RAM 153 of the main controller 131 is stopped. The supply may be stopped.

  (14) In each of the above embodiments, when the relay board 165 is provided and the harnesses H and H1 that electrically connect the relay board 165 and the main control device 131 are removed, the RAM 153 of the main control device 131 is removed. Although power is not supplied, this may be changed. For example, when a harness is provided between the stop operation boards 194 to 196 of the stop operation devices 191 to 193 and the main control device 131, power is not supplied to the RAM 153 of the main control device 131 when the harness is removed. It may be configured. That is, the stop operation boards 194 to 196 may be configured to function as a relay unit.

  (15) In each of the above embodiments, the signal line LN1 from the start detection sensor 71a is fixed to the start operation board 182 with solder or the like, but may be connected via a connector. Similarly, the signal line LN3 from the stop detection sensors 72a to 74a may be connected to the stop operation boards 194 to 196 via a connector.

  (16) In each of the above embodiments, the start operation device 181 and the stop operation devices 191 to 193 are configured to include the operation substrates 182 and 194 to 196, respectively, but without providing these operation substrates 182 and 194 to 196, The signal lines from the start detection sensor 71a and the stop detection sensors 72a to 74a may be connected to the relay board 165.

  (17) In each of the above-described embodiments, the entire back side opening 201 of the accommodation space 200 may be closed by the relay substrate 165. In this case, insertion of a finger or a fraudulent jig into the accommodation space 200 can be reliably suppressed.

  (18) In each of the above embodiments, the RAM 153 includes the backup area 153a. However, the RAM 153 does not include the backup area 153a, and the data is stored and retained without saving the data when the power is turned off. It is good. In this case, the backup capacitor 161c and the backup power supply generation circuit 281 function as a memory holding power supply.

  (19) It is assumed that a pseudo signal corresponding to the signal from the reel index sensor 55 provided in the reel unit 41 is output to the main controller 131 in the case of an illegal act using the signal output device. In this case, the signal line from the reel index sensor 55 may be relayed by the relay board 165. The relayed signal is preferably output to the main controller 131 via the harness H and provided with trace means. Thereby, the act of removing the signal line from the reel index sensor 55 from the relay board 165 and connecting the signal output device can be suppressed.

  (20) 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.

  (21) In each of the above-described embodiments, a belt printed with a pattern 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.

  (22) 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.

  (23) In each of the above embodiments, the so-called A type slot machine has been described. However, the B type, the C type, the combined type of the A type and the C type, the combined type of the B type and the C type, and the 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 embodiment 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.

  (24) 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 identification information (identification information).

  (25) In each of the above-described embodiments, an example in which the slot machine 10 is embodied has been described. However, the present invention may be applied to a gaming machine in which a slot machine and a pachinko machine are combined. 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.
