  In addition, the game board 400 is provided on the center frame 420, and displays a decorative symbol in a fluctuating manner or a fixed display of the decorative symbol in accordance with a jackpot lottery relating to one of the first special symbol and the second special symbol. A decorative pattern display device 479 is provided. The variable display and the fixed display of the decorative symbol based on the control by the sub control board 940 are substantially synchronized with the variable display and the fixed display of the first special symbol and the second special symbol by the main control board 920. In the variation display of the decorative symbol, a more complicated effect is executed than in the variation display of the first special symbol and the second special symbol.

  Here, operations of various devices of the game board 400 will be described. Prior to the description, various game states and transitions between the game states will be described. In the normal gaming state (normal gaming state), the jackpot winning probability of the first special symbol and the second special symbol is low, and the fluctuation display time of the first special symbol and the second special symbol is long ( Hereinafter, it is also referred to as a “low probability non-time saving state”). The gaming state changes based on the jackpot winning. There are five types of jackpots pertaining to the first special symbol: standard probability jackpot, sudden probability jackpot, latent probability jackpot, standard time jackpot, and sudden time jackpot. The type of jackpot related to the second special symbol is the standard probability jackpot. , And two types of standard time college hits. When the player wins the standard probability change big hit or the sudden probability change big hit, the game state temporarily shifts to the special game state in which the special winning device 433 is intermittently allowed to enter, and after the special game state ends, the first special game state is set. The jackpot winning probability of the symbol and the second special symbol is higher than that of the normal game state, and the fluctuation display time of the first special symbol and the second special symbol is shorter than the normal game state (hereinafter, “high”). (Referred to as "probability saving time state"). The high probability time reduction state is maintained until the next jackpot win. Also, in the case of winning the latent probability change big hit, after once shifting to the special gaming state, the big hit winning probability of the first special symbol and the second special symbol is higher than the normal gaming state, the first special symbol A transition is made to a gaming state in which the variable display time of the symbol or the second special symbol is the same as the normal gaming state (hereinafter, referred to as a “high-probability non-saving time state”). The high probability non-time saving state is maintained until the next jackpot winning. In the case of winning the standard time savings jackpot, after the transition to the special gaming state, the jackpot winning probability for the first special symbol and the second special symbol is the same low probability as the normal gaming state, the first special symbol And a game state in which the variable display time of the second special symbol is shorter than the normal game state (hereinafter, referred to as “low probability time reduction state”). The low probability reduction time state is maintained until a predetermined number of times (for example, 100 times) of unit display control related to one of the first special symbol and the second special symbol is completed, and thereafter, the gaming state is changed to the normal gaming state. Return. In the case of a large hit in the high-probability time-short state and the high-probability non-time-short state, one of the probable big hits (standard probable big hit, sudden probable big hit) , The probability of distributing to the big odds of latent probability) is large. Hereinafter, the operation of various devices of the game board 400 will be described in chronological order.

  On the main control board 920, a winning random number relating to a special symbol (common to the first special symbol and the second special symbol), a symbol random number relating to the special symbol (common to the first special symbol and the second special symbol), a stop pattern random number, Various kinds of fluctuation pattern random numbers are generated, and in various game states, when a game ball enters the first starting winning device 431 or the second starting winning device 432, a winning random number related to a special symbol, a symbol random number related to a special symbol. Then, a stop pattern random number is obtained and stored in a predetermined area of the RAM of the main control board 920. At this time, when the special winning device 433 is not in operation, unless both the first special symbol and the second special symbol are being displayed in a variable display or in a fixed display, immediately after the storing, or in addition to the first special symbol and the second special symbol. If any of the special symbols is displayed in a floating display or in a fixed display, all of the jackpot lottery rights relating to the first special symbol acquired in advance and the previously acquired and subsequent acquired right (2) After all the jackpot lottery rights related to the special symbol have been exhausted, it is determined whether or not a jackpot has been won based on the obtained random numbers related to the special symbol. In addition, the winning probability of the big hit according to the first special symbol is, as described above, specifically, a high probability state (high probability time reduction state, high probability non-time reduction state) or a low probability state depending on the current gaming state. (Low-probability time-saving state, low-probability non-time-saving state). Specifically, the winning probability of a big hit in the high-probability state is higher than the winning probability of the big hit in the low-probability state. When the big hit is won, the stop symbol of the first special symbol is further determined based on the symbol random number related to the acquired special symbol. Depending on the type of the stop symbol, it is determined which of the standard probability big hit, the sudden probability variable hit, the latent probability variable big hit, the standard time saving big hit and the sudden time saving big hit. Note that the distribution probability of various big hits varies depending on the current game state, specifically, depending on whether the game is in a high probability state or a low probability state. The distribution probability to the big hit, the sudden change big hit, the latent probability big hit) is higher in the high probability state than in the low probability state. On the other hand, when a big hit is lost and a small hit is won, a small hit symbol is set as a stop symbol, and when no small hit is won, a lost symbol is set as a stop symbol. You.

  After the jackpot lottery related to the first special symbol, the current gaming state, the lottery result of the jackpot lottery, the random number of the stop pattern, various fluctuation pattern random numbers, the total reservation of the right to the jackpot lottery related to the first special symbol and the second special symbol The change display time of the first special symbol is determined based on the number, and the change pattern of the decorative symbol is selected. After that, the variable display of the first special symbol on the first special symbol display device 471 and the variable display of the decorative symbol on the decorative symbol display device 479 (fluctuation effect) are started, and the first special symbol is displayed over the variable display time. In this case, the variable display according to the fixed pattern is continued, and in the case of the decorative design, the variable display is executed according to the variable pattern over the variable display time. As the variable display time elapses, the stop symbol is fixedly displayed as the first special symbol, and the symbol corresponding to the stop symbol of the first special symbol is definitely displayed as the decorative symbol. The fixed display of the first special symbol and the decorative symbol is continued for a certain period of time.

  When the stop symbol of the first special symbol is a big hit symbol, the game state shifts from the normal mode to the special game state after the first special symbol is determined and displayed. In the special game state, the opening / closing mechanism of the special winning device 433 intermittently moves to the entry allowable arrangement a predetermined number of times. After shifting to the entry allowable arrangement, the large prize winning device 433 is set depending on whether a predetermined number (for example, 10 balls) of game balls enter the large prize winning device 433 or when a predetermined maximum opening time has elapsed. Move to Intrusion Prevention configuration. Thereafter, after the elapse of the predetermined closing time, the special winning device 433 again shifts to the entry allowable arrangement. This opening and closing operation is repeated a predetermined number of times. The number of repetitions of the opening / closing operation in accordance with the shift of the special winning device 433 to the entry allowable arrangement, the maximum opening time to stay in the entry allowable arrangement, and the like vary depending on the type of the big hit (the type of stop symbol). Specifically, in the special game state based on the standard probability variable jackpot and the standard time saving jackpot, the opening / closing operation in which the maximum opening time is 29.5 seconds and the closing time is 2.0 seconds is repeated 16 times. Note that, after a standby time (opening time) of 10.0 seconds from the start of the special game state, the transition to the first entry allowable arrangement is started, and 15.0 seconds from the transition to the 16th entry inhibition arrangement. After the waiting time (ending time), the special game state ends. On the other hand, in the special game state based on the sudden change big hit, the latent change big hit and the sudden time saving big hit, the opening and closing operation in which the maximum opening time is 0.8 seconds and the closing time is 2.0 seconds is repeated only twice. In addition, after a standby time (opening time) of 3.2 seconds from the start of the special game state, the movement to the first entry allowable arrangement is started, and 3.2 seconds from the movement to the second entry prevention arrangement. After the waiting time (ending time), the special game state ends. After the end of the special game state, as described above, the game state is shifted to the game state according to the type of the big hit.

  When the stop symbol of the first special symbol is a small hit symbol or a lost symbol, the game state is not changed even after the final display of the first special symbol. However, when a small hit is won, the big prize winning device 433 operates in the same manner as in the special game state based on the sudden change big hit, the latent change big hit and the sudden time saving big hit.

  In the above description, the case where the right of the jackpot lottery according to the first special symbol is exhausted has been described, but also in the case where the right of the jackpot lottery according to the second special symbol has been exhausted, the type of the jackpot is as described above. Except that the first special symbol is different from the second special symbol and that the right of the jackpot lottery related to the second special symbol is digested in preference to the right of the jackpot lottery related to the first special symbol. Since it is almost the same as the case of the one special symbol, the first special symbol and the second special symbol are replaced with the second special symbol and the first special symbol, respectively, and the repeated description is omitted.

  In various game states, when a game ball enters the starting device 436, a winning random number related to a normal symbol is obtained and stored in a predetermined area of a RAM (not shown) of the main control board 920. At this time, in the case where the second start winning device 432 is not in operation, immediately after the normal symbol is not in the variable display or the fixed display, immediately before the normal symbol is in the variable display or the fixed display, the preceding is performed. After all the winning lottery rights that have been acquired have been consumed, it is determined whether or not a winning has been won based on the winning random number associated with the acquired ordinary symbol. Depending on the gaming state at the time of determination, the winning probability per hit is, specifically, a time reduction state (high probability reduction state, low probability reduction state) or a non-reduction state (low probability non reduction state, high probability non reduction state, (Special game state), and the winning probability in the time reduction state is higher than in the non-time reduction state. When a winning is won, a predetermined winning symbol is set as a stop symbol, and when no winning is won, a predetermined losing symbol is set as a stop symbol. After the winning lottery, the fluctuation display of the ordinary symbols is started, and in the non-time reduction state, the fluctuation display in a fixed pattern is continued for a predetermined fluctuation display time (for example, 3.0 seconds), and the time reduction state is set. In the meantime, the fluctuation display in the same pattern as in the normal game state is continued for a predetermined fluctuation display time (for example, 0.5 seconds) shorter than the non-time saving state. With a lapse of a predetermined time according to the game state, a stop symbol is fixedly displayed as a normal symbol for a certain period of time.

  When the stop symbol of the ordinary symbol is a hit symbol, the state of the entry allowable arrangement of the movable bridge 70, which is an entry probability changing mechanism for changing the entry probability to the second starting winning device 432, after confirming the display of the ordinary symbol is changed. Keep long. Specifically, in the case of winning in the non-time saving state, the movable bridge 70 typically enters a predetermined number of times (for example, once) for a predetermined maximum opening time (for example, 0.2 seconds). In the case of the winning in the time saving state, the movable bridge 70 is typically longer than the non-time saving state by a predetermined number of times (for example, three times) larger than the non-time saving state. The transition to the entry-permitted configuration is made over the maximum opening time (for example, 1.9 seconds). However, when a predetermined number (for example, 10 balls) of game balls have entered the second starting winning device 432, the movable bridge 70 forcibly shifts to the non-connection state in which the approaching prevention arrangement is provided, and The operation of the movable bridge 70 based on the winning is completed.

The firing control unit 902 operates the ball feeding solenoid 332 based on the ball feeding control signal in the ON state, and operates the firing solenoid 334 based on the reception of the firing solenoid control signal in the ON state and the resistance value of the variable resistor 253. Let it. As a result, game balls are sequentially fired from the firing device 330 with an intensity corresponding to the resistance value of the variable resistor 253 (the amount of rotation of the firing handle 252).

  The signal relay unit 903 outputs an on-state initialization signal to the main control board 920 when the initialization switch 907 is pressed. In the main control board 920, the storage information stored in the RAM of the main control board 920 is initialized in response to receiving the initialization signal in the ON state. In addition, the signal relay unit 903 outputs an ON ball overflow signal to the main control board 920 when the ball overflow switch 249 detects a game ball. Note that the main control board 920 outputs a low-speed payout signal to the payout control board 930 based on the detection of the ball overflow signal in the ON state, and the payout control board 930 that has received the low-speed payout signal outputs the payout motor 542. The rotation speed (payout speed of the game balls from the payout device 540) is reduced. Conversely, a high-speed payout signal is output to the payout control board 930 based on the detection of the ball overflow signal in the off state, and the payout control board 930 receiving the low-speed payout signal increases the rotation speed of the payout motor 542. It will be.

  The power supply monitoring board 910 monitors a power supply state from the power supply / emission control device 900 and outputs a power failure signal to the main control board 920 in response to a transition to the power failure state. A signal relay unit 912 for relaying power supply and transmission of various signals between the device 900 and the main control board 920 is included. The power supply monitoring unit 911 monitors a DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 901, and when the voltage becomes less than 22 volts, determines that a transition to a power failure state is made, and turns on the power. Is output to the main control board 920. The main control board 920 recognizes the shift to the power failure state by receiving the power failure signal in the ON state.

  The main control board 920 generally controls the operation of the gaming machine 100. On the main control board 920, an MPU (not shown) as a one-chip microcomputer is mounted. The MPU includes a CPU (not shown) as an arithmetic processing unit, a ROM (not shown) storing various control programs and fixed data executed by the CPU, and various data temporarily stored when executing the control programs. And the like (not shown) for storing the same. Various other circuits such as a timer circuit (not shown), a counter circuit (not shown), a clock generation circuit (not shown), and a signal transmission / reception circuit (not shown) are mounted on the main control board 920. I have. The RAM of the main control board 920 is configured such that internal data can be maintained (backed up) by power supply of the backup voltage from the power supply / emission control device 900 even after shifting to the power failure state.

  The payout control board 930 controls the payout operation of the game balls by the payout device 540 according to the instruction from the main control board 920 and the lending operation of the game balls by the payout device 540 according to the operation of the game ball lending device 290. Like the main control board 920, the payout control board 930 includes an MPU (not shown) as a one-chip microcomputer including a CPU (not shown), a ROM (not shown) and a RAM (not shown), and a timer circuit. Various circuits such as a counter circuit (not shown), a clock generation circuit (not shown), and a signal transmission / reception circuit (not shown) are mounted. Note that, similarly to the RAM of the main control board 920, the RAM of the payout control board 930 may be configured to be able to maintain internal data even in a power failure state.

  The sub control board 940 controls the operation of various effect devices, various light emitting devices, various audio devices, and the like based on instructions from the main control substrate 920. Note that the RAM of the sub control board 940 may be configured to maintain internal data even in a power failure state, similarly to the RAM of the main control board 920.

  Next, the configuration of the start winning device 450 will be described. FIG. 10 is a perspective view of the start winning device 450, and FIG. 11 is a perspective view showing a state where the start winning device 450 is attached.

As shown in FIG. 10, the start winning device 450 includes a front block member 11 and a rear block member 12, each of which is fixed by a screw or the like.
The front block member 11 is a member formed of a transparent resin material, and has a front plate 13. The rear block member 12 is formed by fixing a plurality of members with screws or the like.

  As shown in FIG. 11, the start winning device 450 is fixed by being screwed to the game board 400 through a screw hole. In the start winning device 450, a portion in front of the front plate 13 protrudes from the front surface of the game board (the base 401 to which the nail 411, the windmill 412, and the like are attached) constituting the game board 400.

  As described above, the starting winning device 450 has the general winning device 438, the first starting winning device 431, and the second starting winning device 432, and cannot enter the winning opening corresponding to the entrance of each winning device. The game ball is caused to flow down and discharged from the discharge port 401A.

  The start winning device 450 has a distribution projecting portion 15 on the left side from the center thereof, and a game ball flowing down from above has a right guiding path 30 on the right side of the distribution projecting portion 15 and a left side of the distribution projecting portion 15. To the left taxiway 50.

  As shown in FIG. 12, a part of the game ball passing through the right guideway 30 enters the winning opening of the first start winning device 431, while the rest flows down the side of the first start winning device 431, and discharge guides. The game board 400 is discharged to the rear side through the path 31 and the discharge port 401A. The game balls that have flowed down to the inclined surfaces 41 and 42 are similarly discharged to the back side of the game board 400 through the discharge ports 401A.

  As shown in FIG. 13, a part of the game ball passing through the left taxiway 50 enters the winning opening of the general winning device 438, while the rest is adjacent to the general winning device 438 and is directed downward toward the right side. It passes through the guide wall 16 inclined to the bottom and enters the windmill 61 from the downflow opening 18. The windmill 61 distributes the game balls to the right and left sides according to the position and direction of the flow of the game balls, and allows the game balls distributed to the right to enter the second starting guide path 54, while the game balls distributed to the left are It flows downward as it is, and is discharged to the back side of the game board 400 through the discharge port 401A.

The game balls distributed to the right side are guided to the second starting guideway 54, pass through the relay plate 62 which is slightly inclined downward toward the downstream side, and flow down from the clune 63, and thereafter, into the winning guideway 55 or the discharge guideway. 56. The game balls distributed to the winning guideway 55 are guided to the second starting winning device 432 and enter the winning opening. On the other hand, the game balls distributed to the discharge guide path 56 are discharged to the back side of the game board 400 through the discharge port 401A.
Note that a general winning switch 448 (FIG. 9) is provided downstream of the general winning device 438, and start winning switches 441 and 442 (FIG. 9) are provided downstream of the first starting winning device 431 and the second starting winning device 432. Each is provided, and a winning game ball is detected.

  As described above, the first starting winning device 431 has a structure in which the entered game balls are guided to the rear side of the base 401 without changing the entry probability. On the other hand, the second startup winning device 432 changes the entry probability by an entry probability changing mechanism installed on the upstream side that changes the entry probability. This approach probability changing mechanism is achieved by complicating the movement of the game ball. It should be noted that a detection switch 65 (FIG. 9) for detecting a game ball passing through the second starting guide path 54 is provided below the relay board 62. When a game ball is detected, the detection switch 65 is provided to the start winning device 450. The player is notified that the game ball has entered the entry probability changing mechanism by lighting or blinking the light-emitting portion, or performing an effect such as playing a specific sound effect.

  Specifically, the start winning device 450 includes a crane 63, a movable bridge 70, a backside depression 81, and a reflection step 82 as an approach probability changing mechanism.

  As shown in FIG. 14, the clune 63 has a fall prevention wall 63 a formed on the outside to prevent the game balls from falling, is distributed to the right side from the windmill 61, and is slightly inclined downward toward the downstream side. This prevents a game ball entering through the plate 62 from falling out of the clune 63 and falling. The fall prevention wall 63a is provided higher than the wall 62a provided on the relay plate 62, assuming the centrifugal force of the game ball.

  The spiral step 63b is formed by a spiral step shape that inclines downward toward the inside or a conical wall surface whose apex is located on the lower side, and a flowing hole provided at the center while rotating the entering game ball. 63c. The innermost peripheral portion of the crown 63 has an inner wall portion 63d extending slightly (0.3 to 1.0 cm) downward, and the inner peripheral surface of the inner wall portion 63d causes a flow-down hole. 63c is configured. The downflow hole 63c is formed larger than a game ball.

  The game ball that has entered the clune 63 changes its traveling direction by the fall prevention wall 63a, starts rotating, and is guided inward by the spiral step 63b while rotating, and falls downward from the downflow hole 63c. At this time, since the time from when the game ball enters the clune 63 to when it flows down the downflow hole 63c varies depending on the speed and the traveling direction at the time when the game ball enters, it is necessary to predict the fall timing of the game ball. Is difficult and can complicate the movement of the game ball.

  Here, as shown in FIG. 15, a movable bridge 70 capable of transition between a connected state and a disconnected state is provided immediately below the downflow hole 63c. As shown in FIG. 16, the movable bridge main body 71 has a guide wall 71a, a bottom surface 71b, a rotating shaft holding portion 71c, a lever holding portion 71d, a lever through hole 71e, and a sensor detector 71f. ing. Note that the directions in FIG. 16 are based on when the movable bridge 70 is in the connected state (FIG. 15).

  The guide wall portion 71a is a wall portion extending in a substantially vertical direction, and is connected substantially perpendicularly to the bottom surface 71b in a state where a connecting portion draws a curved surface. The bottom surface 71b has, on the front side, a forward portion 71bx inclined slightly downward in the backward direction and a backward portion 71by inclined slightly upward in the backward direction. A valley state is formed by the portion 71by. The bottom surface 71b has a slight downward slope from the left to the right, and guides the game ball from the left direction, which is the traveling direction, to the right. The rotating shaft holding portion 71c has a cylindrical shape, and holds the rotating shaft 73 at a central portion.

  The lever holding portion 71d is formed on the left side of the movable bridge main body 71, and has an upper surface at a position higher than the bottom surface 71b. The lever holding portion 71d is formed to be thicker than the bottom surface 71b, has a vertically extending lever through hole 71e in the left and right direction, and has an end of the lever 75 penetrated. The sensor detector 71f is formed only in the rear half of the lever holding portion 71d, and extends in an L shape from the lever holding portion 71d. Note that, as shown in FIG. 17, the sensor detection body 71f is located right above the detection sensor 77 in the connected state, is detected by the detection sensor 77, and the detection result is supplied to the main control board 920. .

  As shown in FIG. 16C, the movable bridge main body 71 has a bridge wall surface 71ax, a bottom surface 71b, and a lever holding portion 71d that are smoothly connected to each other to form one movable bridge front surface 71g.

  As shown in FIG. 15, the lever 75 has a shaft portion that penetrates the lever tip end portion 75a, which is one end thereof, into the lever through hole 71e, and rotates around the lever rotation shaft holding portion 75c at the other end. , And rotatably held by a lever rotation shaft 76. An elongated crank moving hole 75b is formed near the center of the lever 75, and the first shaft 74a of the crank 74 is held in a penetrated state. The lower end of the second shaft 74b is above the lever 75, and the second shaft 74b can move on the upper portion of the lever 75 regardless of the position of the lever 75. The upper side of the second shaft 74b is connected to the bridge connection motor 462, and the second shaft 74b is rotationally driven by the power of the bridge connection motor 462, and the lever 75 is moved by moving the position of the first shaft 74a. Rotational movement about the lever rotation shaft 76 is performed. This rotational movement is transmitted so as to rotate the movable bridge main body 71 in a horizontal direction.

  As described above, the movable bridge 70 causes the lever 75 to rotate about the lever rotation shaft 76 by the rotation of the crank 74 that transmits the power of the bridge connection motor 462, and the rotation of the lever 75 is changed to the lever holding portion 71d. The movable bridge body 71 is rotated about the rotation shaft 73 by about 90 °.

  As a result, the movable bridge 70 has a connected state in which the longitudinal direction of the movable bridge main body 71 is parallel to the left-right direction (FIG. 15) and a disconnected state in which the longitudinal direction of the movable bridge main body 71 is parallel to the front-rear direction (FIG. 17). ).

  At this time, under the control of the main control board 920, the bridge connection motor 462 moves the lever tip portion 75a to the leftmost position (FIG. 15) at the first speed, for example, and stops it for a predetermined time (for example, 0.5 seconds). After that, the lever tip 75a is moved to the far right (FIG. 17) at a second speed greater than the first speed.

  As a result, the transition time from the disconnected state to the connected state can be lengthened, and the transition time from the connected state to the disconnected state can be performed in a short time. The movement of the main body 71 can be changed. Further, by adjusting the stop time of the connection state, it is possible to control the probability that the game ball enters the winning guide path 55.

  Here, as described above, the bridge connection motor 462 can transition the movable bridge 70 to the connected state and guide the game ball to the second start winning device 432 when the stop symbol of the normal symbol is a hit symbol. However, it is not always necessary to make a transition to the connected state when the symbol is normally won. For example, in the normal game state, the bridge connection motor 462 controls the connection state, the non-connection state, and the transition time to these, periodically establishes the connection state, and enters the game ball into the winning guideway 55 with a certain probability. In this case, the movable bridge 70 may be operated at a constant speed, or the movable bridge 70 may be operated at a plurality of speeds using the first speed and the second speed. It is good also as composition.

  As shown in FIG. 15, in the connected state, the movable bridge main body 71 causes the game ball to drop onto the movable bridge main body 71 so that the bottom surface 71 b is disposed directly below the downflow hole 63 c, and the game ball is mainly At the winning guide path 55. A prize guide plate 85 having a passage surface at substantially the same position as the bottom surface 71b is installed in the prize guide path 55, and guides a game ball that has entered the prize guide plate 85 to the second starting prize device 432.

  At this time, as shown in FIG. 18, the movable bridge 70 can arrange the front 71g of the movable bridge parallel to the left-right direction, that is, the front 71g of the movable bridge can be arranged in front of the player. The movable bridge 70 preferably includes an opportunity information display section 71ga that displays words such as “CHANCE” and “now!” By sticking or printing a sticker, utilizing a large area of the front 71g of the movable bridge. . This allows the player to recognize that the current state is the timing at which the second starting winning device 432 causes the game ball to enter.

  Note that the winning guide plate 85 has an inverted S-shape that curves from left to right after bending from back to front, has a slight downward slope in the right front direction, and has a wall portion 85a on its front surface. Is formed. The winning guide plate 85 guides a game ball entering from behind the front 71g of the movable bridge in the connected state to a front side of the front 71g of the movable bridge, and a second start located at a front side of the front 71g of the movable bridge. The player enters the winning opening of the winning device 432. This makes it easier for the player to visually recognize that the game ball has entered the second start winning device 432.

  On the other hand, as shown in FIG. 17, in the disconnected state, the movable bridge main body 71 arranges the bottom surface 71 b so as not to overlap directly below the downflow hole 63 c to form a relay space connecting to the discharge guide path 56. . That is, in the non-connection state, the movable bridge 70 allows the flowing game balls to pass through the movable bridge main body portion 71 so that the game balls fall on the first discharge passage surface 91 arranged below the movable bridge main body portion 71. At the same time as dropping, the game balls are guided mainly to the discharge guide path 56. The discharge guide path 56 includes a first discharge passage surface 91 and a second discharge passage surface 92. The first discharge passage surface 91 has a slight downward inclination to the right, and allows the game balls to enter the second discharge passage surface 92. The second discharge passage surface 92 has an inclination that is slightly lowered rightward and forward, and causes the game balls to drop from the second start winning device 432 and guide them to the discharge port 401A.

  At this time, as shown in FIG. 19, the movable bridge 70 can arrange the front 71g of the movable bridge vertically in the left-right direction, that is, at a position where it is most difficult for the player to visually recognize the front. Therefore, the movable bridge 70 can make the player recognize that the current state is a timing at which the second starting winning device 432 cannot enter the game ball.

  In a general game machine, many components move in a direction parallel to the game board 400, that is, in the vertical and horizontal directions. For example, in the case of an apparatus having a door structure having a rotation axis in the left-right direction or the up-down direction, a door surface having a large area is laid down in parallel to the front-rear direction by transitioning to an open state, which is an entry-permissible arrangement. Low visibility to the player in the arrangement.

  The movable bridge 70 can be arranged at a position where the longitudinal direction of the movable bridge main body portion 71 is aligned with the front surface of the front plate portion 13 in the connection state in which the movable bridge 70 is allowed to enter. It is possible for the player to reliably visually recognize the front 71g of the movable bridge having the above. On the other hand, in the non-connection state, which is the approach preventing arrangement, the right side portion of the movable bridge main body 71 is largely projected forward, and the unique movement due to the horizontal rotation makes the movable bridge main body 71 stand out. Can be made.

  Also, unlike the normal winning device that opens the door to open the winning opening, in the movable bridge 70, when the gaming ball wins the winning opening of the second starting winning device 432 in the connected state, the lower side supports the lower side of the game ball while supporting it. In the non-connected state, the game ball that does not win the winning opening of the second starting winning device 432 can be guided to the rear side of the movable bridge 70. For this reason, the visibility at the time of winning can be improved for the player, while the visibility at the time when the game ball does not win can be reduced. The event that the movement of the movable bridge 70 from the disconnected state to the connected state is slightly delayed with respect to the falling timing of the game ball, and the game ball falls from the edge of the movable bridge 70, It is difficult for the player to visually recognize an event in which the game ball does not win due to a slight shift in timing. Therefore, in the movable bridge 70, the player can watch the winning of the game ball and amplify the joy, and the movable bridge body 71 covers the moment when the game ball is guided to the discharge guide path 56 by a slight time difference. It is not necessary to hide and allow the player to visually recognize the player, and it is possible to reduce discouragement of the player when no prize is won.

  Moreover, the game balls guided to the winning opening of the second starting winning device 432 by the movable bridge 70 flow down to the downstream side while being guided from the rear side to the front side by the winning guiding plate 85. For this reason, it is possible to make it easier for the player to visually recognize the winning of the game ball due to the connection state of the movable bridge 70, and it is possible to suitably realize the winning effect.

  Further, in the movable bridge 70, a stepping motor is used as the bridge connection motor 462 (FIG. 9), and the drive of the bridge connection motor 462 allows the movable bridge main body 71 to perform non-uniform movement. This allows the player to watch the movable bridge main body 71. Note that the driving force of the movable bridge 70 is not limited to the stepping motor, and various driving sources such as a DC motor and a solenoid can be used. Alternatively, the movable bridge 70 may be operated by a uniform movement such that the switching speed between the connected state and the disconnected state is constant. The movable bridge main body 71 may be formed of a colorless and transparent synthetic resin so as to be transparent. However, it is preferable that the movable bridge main body 71 is formed of a colored transparent or opaque resin material and a color different from the surroundings is added. Thereby, it becomes possible for the player to watch the movable bridge main body 71.

  In the approach probability changing mechanism of the present invention, two mechanisms that further complicate the movement of the game ball are provided.

  As shown in FIG. 14 (B), in the rear direction of the movable bridge main body 71, a back-side recess 81 is provided which is recessed toward the rear side of the flow-down hole 63 c. The back side recess 81 is formed to be slightly larger than the size of one game ball, and is directly connected to the discharge guide path 56, forming a relay space connecting the movable bridge main body 71 to the discharge guide path 56. Have been.

  In other words, even if the game ball falls on the movable bridge main body 71 in the connected state at the same timing, the game ball cannot stay on the bottom surface 71b due to rebound or the like, and the game ball is recessed on the back side. There is a case where the air is guided to the discharge guide path 56 through the passage 81. In order to make such a case exceptional, it is preferable to provide a valley structure on the bottom surface 71b of the movable bridge main body 71. Also, if a wall portion is formed adjacent to the rear side of the bottom surface 71b, there is a possibility that a game ball is sandwiched between the bottom surface 71b and the wall portion and the movement of the movable bridge 70 is restricted. I will. The movable bridge 70 uses a motor (bridge connection motor 462) as a driving force, and there is a possibility that the movable bridge 70 directly pushes the sandwiched game ball and applies excessive pressure, thereby causing a malfunction. In the movable bridge 70, the game ball that has entered the rear side of the bottom surface 71b can be dropped from the back side recess 81, so that an abnormal situation in which the game ball is sandwiched between the bottom surface 71b can be avoided.

  The first discharge passage surface 91 has a step (for example, about 0.5 to 1.0 cm) higher than the first discharge passage surface 91, and an upper surface is formed in a planar shape facing upward. The provided reflection step 82 is provided. As shown in FIG. 17A, the reflection step 82 is formed in a triangular shape, and overlaps a part of the flow-down hole 63c in the vertical direction. Also, the diameter of the downflow hole 63c is formed to be larger than the diameter of the game ball, and the degree of overlap between the reflection step 82 and the game ball in a planar view varies depending on the falling position in the downflow hole 63c. When the area of the overlapping region in plan view is equal to or larger than a certain value, the game step is reflected upward by the reflection step 82, and when the area is small, the game ball is not reflected.

  That is, even if the game ball falls toward the first discharge passage surface 91 in a disconnected state in which the timing at which the game ball is guided to the winning guide path 55 does not match, the position of the game ball in the downflow hole 63c. Accordingly, there is a case where the game ball is reflected by the reflection step 82, is scooped by the movable bridge main body 71, and is guided to the winning guide path 55. Note that all the game balls may be reflected by the reflection step 82, but in order to make the case where the game balls are guided to the winning guide path 55 exceptional, the area ratio of the overlapping area is limited. However, it is preferable to set the area ratio such that the ratio of the game balls reflected upward is 1/4 or less, and to form the reflection step 82 in 1/4 or less of the area of the downflow hole 63c. Is preferred.

  In this way, in the start winning device 450, whether the game ball is guided to the winning guide path 55 or the discharge guide path 56, an element other than the position (connected or disconnected) of the movable bridge main body 71 is incorporated. Can complicate the movement of the game ball and create a state in which it is not possible to guide to which guideway until the end, so that the player's interest can be attracted and the expectation can be maintained for a long time .

  In general, when a plurality of (for example, two) starting prize winning devices are provided, the two starting prize winning devices are often arranged close to each other so that a player can visually recognize them at the same time. However, if two starting prize devices are provided in the vicinity, the probability that a game ball passing through a path separated from the two starting prize devices will be guided to the starting prize device will be almost zero, and the player's expectation will be reduced. It was difficult to maintain the feeling. In other words, at the upstream branch point away from the starting winning device, the game ball that flows down to the downstream side that cannot win the starting winning device is less likely to be interested in the behavior of the game ball, As the percentage of the game increases, there is a possibility that the will to continue the game is reduced.

  On the other hand, when a large number of game balls approach the start winning device, the ratio of game balls that do not enter the winning opening near the start winning device must be set relatively high. In this case, the percentage of the game balls that do not win even when approaching the start winning device increases, and the player may feel uncomfortable.

  In the start winning device 450 of the present invention, while the first starting winning device 431 and the second starting winning device 432 are arranged in the vicinity, the downstream opening which is the entrance to the second starting guideway 54 toward the second starting winning device 432. The portion 18 is provided at a position largely separated from the entrance of the first start winning device 431. Thereby, it becomes possible to guide the game ball flowing down through the left guiding path 50 largely separated from the entrance of the first startup winning device 431 to the entrance side of the second startup winning device 432.

  Specifically, as shown in FIG. 12, the game ball guided to the right taxiway 30 passes near the entrance of the first start winning device 431, so that the player moves the game ball to the first start winning device 431. You can expect to win.

  On the other hand, a part of the game ball flowing down to the left side from the distribution projecting portion 15 is guided from the flow-down opening 18 to the second starting guide path 54, and then passes through the relay board 62, the clune 63, and the movable bridge 70. It is guided to either the discharge guide path 56 or the winning guide path 55. That is, in the start winning device 450, there is a possibility that the game ball via the left guiding path 50 largely separated from the first starting winning device 431 and the second starting winning device 432 is guided to the second starting winning device 432. And the player's expectation can be maintained.

  In addition, the upper end portion of the flow-down opening 18 that opens upward on the left side of the distribution projecting portion 15 is continuous from the upper end of the flow-down opening 18 diagonally upward in the left-right direction, and guides game balls to the flow-down opening 18. The guiding wall surfaces 16 and 17 are formed integrally with the wall surface of the flow-down opening 18 by synthetic resin. The guide wall surfaces 16 and 17 are set to have a length substantially equal to or greater than the left and right width (lateral width) of the flow-down opening 18 on each of the left and right sides of the flow-down opening 18, and the game flows down from above the flow-down opening 18. Most of the spheres are configured to be able to be guided to the downflow opening 18. Thereby, it is possible to leave the possibility of guiding the second starting winning device 432 to many of the game balls flowing down the left side of the distribution projecting portion 15. The length of the guide wall surfaces 16 and 17 in the left-right direction is preferably such that the combined length of the left and right sides thereof is substantially equal to or greater than the width of the flow-down opening 18, and is approximately twice or more. It is preferred that

  Here, the guide wall surfaces 16 and 17 may be configured such that a plurality of nails are attached to the base 401 constituting the game board 400 to guide the game ball to the flow-down opening 18. However, since the orientation of the nail can be adjusted at the manufacturing stage or the like, there is a possibility that the player may feel that the game ball is adjusted so as not to go to the flow-down opening portion 18. It is preferable to adopt a configuration in which it is clear that the adjustment is impossible from the viewpoint of appearance. For example, it is preferable to adopt a configuration in which the guide wall surfaces 16 and 17 are formed by a molded product such as a synthetic resin. In addition, it is preferable to provide a part having a configuration in which the guiding direction cannot be adjusted as to other parts that determine whether the game ball is guided to the second starting winning device 432. It is preferable that the distribution protruding portion 15 provided on the upstream side and the shaft portion of the windmill 61 provided on the downstream side of the downflow opening 18 are also formed of synthetic resin or the like so that the guiding direction cannot be adjusted.

  In addition, the bridge connection motor 462 performs a constant operation in the normal game state, and operates the movable bridge 70 at regular intervals at regular time intervals or at regular intervals so that the movable bridge 70 operates to establish a connection state. The control may be performed by the control board 920. In this case, it is preferable to set the winning ratio of the second starting winning device 432 in the normal gaming state to approximately 30% or more of the winning of the first starting winning device 431, approximately half or more, or approximately 6%. It is preferable to set the ratio to be greater than or equal to a certain value, so that the effect of the large separation in the left-right direction of the entrance of the second starting winning device 432 from the entrance of the first starting winning device 431 can be more remarkably exhibited. Can be.

  Next, a detailed configuration of the flow-down opening 18 in the start winning device 450 will be described. As shown in FIG. 20, generally, it is assumed that the gaming machine 100 is installed so as to be inclined so that the upper portion falls backward when viewed from the player. The inclination angle α at this time is ５, that is, 1 °. By the inclination angle α, the game ball can be along the surface of the game board 400 (corresponding to the front surface of the base 401 as a game board, hereinafter, referred to as the board surface) 400A, and the game ball can be placed on a nail head or the like. The game balls can move smoothly without collision.

  However, there are game arcades in which the inclination angle α is not set correctly. Therefore, in the starting winning device 450, in order to motivate the correct setting of the inclination angle α, when the inclination angle α is correctly set, the game ball can be guided to the winning opening with a probability as designed, so that the game ball can be guided to the winning opening. The opening position of the flow-down opening 18 is changed in the front-back direction.

  As shown in FIG. 21, the flow-down opening 18 is formed by being surrounded by the board surface 400A and the end portions 16a and 17a of the guide wall surfaces 16 and 17. The windmill 61 provided below the flow-down opening 18 includes a disk 61a provided on the front surface, a rotating shaft 61b provided to protrude from the board surface 400A and connecting the disk 61a and the board surface 400A, and a rotating shaft 61b. And a rotating blade 61c protruding therefrom. The windmill 61 distributes the game balls flowing down the flow-down opening 18 to the left and right. When the game ball flows down to the opening 18a on the right side of the rotating shaft 61b, the game ball collides with the rotating blade 61c and rotates clockwise while rotating the game ball to the second starting winning device 432. It guides to the 2nd starting guideway 54 following to a mouth. On the other hand, when the game ball flows down to the left side opening 18b on the left side of the rotation shaft 61b, the windmill 61 collides the game ball with the rotating blade 61c and guides the game ball to the discharge port 401A while rotating counterclockwise. I do.

  Here, the guide walls 16 and 17 have ends formed so as to be inclined rightward toward the front, so that the flow-down opening 18 is formed into a parallelogram inclined rightward toward the front. It has a shape. As shown in FIG. 22, when the game ball flows down along the board surface 400A, the width in the left-right direction of the flow-down opening 18 at the center of the game ball is substantially the same on the right and left sides. On the other hand, when the game ball flows down while being away from the board 400A, as shown in FIG. 23, the width of the flow-down opening portion 18 at the center of the game ball in the left-right direction is not the same but becomes larger on the right side and smaller on the left side. ing. That is, when the game ball flows down along the board 400A, the probability of being distributed to the right or left by the windmill 61 is the same, but when the game ball flows away from the board 400A, the windmill 61 Thus, the probability of being assigned to the right is greater than the probability of being assigned to the left.

  As described above, in the flow-down opening 18, the width (width) of the opening right 18a and the opening left 18b is changed according to the position of the game ball with respect to the board surface 400A (that is, the position in the front-back direction), and the opening right 18a is changed. , The width is increased in the forward direction, and the width is reduced in the forward direction on the left side 18b of the opening, thereby changing the probability of being guided to the second starting guide path 54 and the discharge port 401A. Thus, the rate at which the game ball advances to the second starting winning device 432 provided on the downstream side of the opening right 18a and on the downstream side of the second starting guiding path 54 changes according to the inclination angle of the gaming machine 100. . Therefore, it is possible to easily detect that the maker side is out of the set inclination angle based on the ratio of the game balls winning to the second starting winning device 432. As a result, the gaming machine 100 can be easily installed at an inclination angle that is set to a design value set by the manufacturer, and motivation is given to the game hall so that the inclination angle α is set as set. Can be.

  In addition, as shown in FIG. 24, in order to change the width of the opening right 18a and the opening left 18b, steps may be provided at the ends 16a and 17a of the guide wall surfaces 16 and 17. Further, it is not always necessary to have a distribution mechanism (windmill 61) below the opening, and for example, as shown in FIG. 25, the shape of the opening (winning opening) in the first start winning device 431 is directed forward. It is also possible to change the width of the opening in the front-rear direction by adopting a shape in which the width is widened or a shape in which only one side is inclined (not shown). At this time, the side surface can be curved in a curved shape. The point is that the width of the opening may be changed so that the winning probability of the game ball changes according to the position in the front-back direction.

  In addition, the width of the flow-down opening 18 is set within a range of approximately 1.05 times to approximately 1.5 times the diameter of the game ball in order to keep the variation of the flow-down position of the game ball in the left-right direction to a certain value or less. It is preferable to set the value within a range of about 1.05 times to about 1.2 times.

  Next, the appearance probability of a winning symbol will be described. As described, when the game ball enters the first start winning device 431 and the second start winning device 432, the right of the big hit lottery is given, and the lottery is executed with a predetermined big hit lottery probability.

  By the way, the movable bridge 70 is provided in front of the second start winning device 432, and the game ball can enter the second start winning device 432 only when the movable bridge 70 is in the connected state and the timing is matched. . On the other hand, a similar device is not provided before the first start winning device 431, and a game ball can enter the first start winning device 431 regardless of timing. That is, the probability that a game ball can enter the second start winning device 432 is set lower than the first start winning device 431.

  However, there is a difference in the lottery probability of a loss, a small hit, and a big hit between when a game ball enters the first start winning device 431 and when a game ball enters the second start winning device 432. However, there is a possibility that the first starting winning device 431 and the second starting winning device 432 may cause unfairness.

  Therefore, in the gaming machine 100, a sub prize other than the payout of game balls is provided according to the symbol displayed on the decorative symbol display device 479 when a small hit occurs, and the appearance probability of the symbol displayed is set to the first start winning. The change is made between the device 431 and the second start winning device 432.

  As described above, the main control board 920 (FIG. 10) controls the display of the first special symbol and the second special symbol, and controls the timing signal for synchronizing with the first special symbol and the second special symbol. It is supplied to the substrate 940. The sub-control board 940 generates image data to be displayed based on the timing signal, and transmits the generated image data to the decorative symbol display device 479. As a result, the decorative symbol display device 479 displays a decorative symbol corresponding to the first special symbol and the second special symbol.

  Here, the types of the big hits related to the first special symbol and the second special symbol and the combinations of the symbols displayed on the decorative symbol display device 479 in each big hit will be described. As described above, the types of the big hits related to the first special symbol and the second special symbol are roughly classified into two types, a big change big hit and a time saving big hit, and the emission color corresponding to each big hit type. The first special symbol display device 471 and the second special symbol display device 472 display a lottery result relating to the special symbol and the content (type) of the winning in the case of winning.

  In the decorative symbol display device 479, for example, a symbol column in which a plurality of symbols are displayed in a row in the vertical direction is displayed in three columns of left, middle, and right, and three symbol columns are displayed as variable display from top to bottom. Then, the symbols stop sequentially from the left side (see FIG. 26 and the like). When the variable display is stopped, a combination of three symbols in a row is stopped and displayed in the middle of the display screen of the decorative symbol display device 479, and the lottery result and the content of the winning according to the special symbol are determined by the combination of the symbols. Are displayed as exemplified below.

  In the standard probability jackpot, odd symbol combinations composed of the same numeral are stopped and displayed. In the latent probability change big hit, the combination of the design of the same appearance as the small hit is stopped and displayed, for example, the symbol of the character of "small" is stopped and displayed on the left and inside, and the symbol of the number is stopped and displayed on the right. In the standard time jackpot, an even number of symbol combinations composed of the same numerals are stopped and displayed.

  In the sudden change big hit and the sudden time saving big hit, a specific symbol combination which is a predetermined symbol combination and is not used in other big hit types and small hits is stopped and displayed. For example, a combination of symbols according to a predetermined rule such that the left and middle symbols such as “7, 7, 8” are composed of the same numeral, and the right symbol is one greater than the left and intermediate numerals, or “3”. A combination of symbols predetermined by the manufacturer without regularity, such as ", 4,1", is stopped and displayed as a combination of symbols representing a sudden change big hit and a sudden time saving big hit.

  As for the winning probability of the big hit lottery and the small hit lottery, for example, the big hit winning probability in the low probability state including the normal gaming state is set to 1/300, and the big hit winning probability in the high probability state is set to 1/30. Is set to a probability related to the jackpot winning probability (eg, the same probability as the jackpot winning probability or twice the jackpot winning probability), and is 1/300 of the same as the jackpot winning probability in the normal gaming state. Is set to When the small hit is won, the big winning device 433 transitions intermittently to the small hitting gaming state in which the entry is allowed, and thereafter, the gaming state before the small hitting gaming state is continued, that is, If it is the normal game state, the normal game state continues, and if it is the high probability time saving game state, the high probability time saving game state continues. Depending on the small hitting game state due to the small hitting winning, a certain prize ball (for example, payout of 15 balls every time a game ball wins to the big winning device 433, average of 3 balls winning in one small hit is averaged). The player acquires 45 prize balls). The big hit lottery and the small hit lottery are drawn by the main control board 920.

  In addition, in the latent probability change big hit, the large winning device 43 operates so that the same operation as the small hit win or substantially the same operation as seen from the player, the small hit win and the latent probability change big hit are the Although the display result (combination of luminescent colors) is different between the first special symbol display device 471 and the second special symbol display device 472, the display result is the same type of the decorative symbol display device 479 (“small, small”). , Number ”), so that the player can expect to win the big hit with the small hit. The display content of the decorative symbol display device 479 is controlled by the sub-control board 940.

  The main control board 920 performs a lottery with a predetermined winning probability and supplies the lottery result to the sub-control board 940. If the lottery result is a small hit, the main control board 920 selects a small hit symbol to be subsequently displayed on the decorative symbol display device 479 by lottery.

  As a result, when a small hit is won, a small hit symbol in which two “small” characters and one number are arranged in a horizontal line is displayed on the decorative symbol display device 479, and according to the small hit symbol, a supplementary prize is displayed. Is presented. For example, when the number on the numeral board is moved as a variable symbol during a lottery and a small hit symbol is displayed as a stopped symbol after the lottery is confirmed, the number on the rightmost side (hereinafter referred to as a winning digit) The corresponding prize can be set by the game arcade. For example, when any of “1 to 6” is displayed as a winning number (for example, when “4” is displayed as a winning number as shown in FIG. 26), a bonus prize (for example, Candy etc.) are presented. When “7” is displayed as the winning number, a special prize (for example, a numbered ticket that allows a specific gaming device to be used preferentially) is presented from the game hall. If “8 or 9” is displayed as the winning number, no additional prize is presented.

  Here, a lottery probability of a winning number is set in the main control board 920, and a lottery probability of a winning number (hereinafter referred to as a sub-prize lottery probability) is determined by the first start winning device 431 and the second start winning device 432. In the second start winning device 432 device, the winning probabilities of “7” and “1 to 6” to which the sub prize is presented are set higher than the first start winning device 431. Further, the secondary prize winning probability can be changed according to the situation, and a high secondary prize probability state and a normal secondary prize probability state are provided, and in the high secondary prize probability state, the secondary prize winning probabilities of “7” and “1 to 6” are normally set. It can be set higher than the sub prize probability state, or can be set so that only "7" and "1 to 6" are won. For example, the main control board 920 can periodically shift to the high sub prize probability state for only 5 minutes out of 1 hour by setting a timer. At this time, the decorative symbol display device 479 informs that the present state is the high sub-prize probability state and it is a good opportunity to acquire the sub-prize (for example, the character of “sub-prize winning chance” is displayed by the control of the sub-control board 940). Doing so) can give the player an exciting feeling. In addition, the main control board 920 monitors the counter, and sets a high value in the case where the game ball has never entered the big hit even though the game ball has entered the first start winning device 431 and the second start winning device 432 more than 500 times. It is possible to shift to the sub prize probability state. As a result, it is possible to suppress irritation of the player who has not won the jackpot for a long time and to further enjoy the game.

  When “7” and “1 to 6” for which the side prize is presented are won, the frame light emitting devices 271 to 275 provided in the front block 102 emit light to notify the manager (salesperson of the game arcade). It has been made like that. The winning history of the sub prize is recorded in the RAM of the main control board 920, and is displayed according to a request of a player or an administrator. As shown in FIG. 28, for example, when a history button (not shown) provided on the outer frame 101 is pressed, the main control board 920 supplies history information indicating the winning history of the sub prize to the sub control board 940. I do. The sub-control board 940 generates image data based on the history information and displays the image data on the decorative symbol display device 479. As a result, a list of history displays is displayed on the decorative symbol display device 479 as shown in FIG. The history display list is reset when the history button is pressed and held (for example, for one second or longer). This allows the player to collectively receive the prize at the end of the game without informing the manager of the successive prize winnings, so that the player does not have to interrupt the game every time the prize is won.

  As shown in FIG. 9, a setting switch 99 may be provided in the gaming machine 100, and by switching the setting switch 99, the winning probability of the sub prize may be changed. For example, in the case of a campaign such as an anniversary of the opening of a game arcade, it is possible to win a sub prize with a high probability, or to increase the probability of winning a sub prize for an unpopular gaming machine. By causing the setting switch 99 to switch an arbitrary number of winning probabilities of two or more, it is possible to set the winning probability of the sub prize according to the situation. Further, the setting switch 99 may have a function of inputting a winning probability of a sub prize.

  In this way, by making the sub-prize lottery probabilities different between the first start winning device 431 and the second start winning device 432, the game balls can easily enter between the first start winning device 431 and the second start winning device 432. , The feeling of unfairness caused by the game can be reduced, and the player can further enjoy the game. Further, the pleasure of the game can be increased by the presence of the supplementary prize.

  Note that, in the above-described embodiment, a numeral table is displayed as a result of the lottery, and a case where a small hit is displayed when two "small" characters and one number are arranged in a horizontal line. Stated. The present invention is not limited to this, and there is no limitation on the small hit symbol. It suffices if a plurality of small hit symbols are prepared and a sub prize is awarded in accordance with the small hit symbol which has been won as a result of the sub prize lottery.

  Further, the present invention may be applied to a gaming machine which has a big hit when a predetermined combination of symbols is stopped and displayed (for example, when the same numbers are arranged in a row). A supplementary prize may be given. As in the above embodiment, when the probability of the next big hit changes depending on whether the numbers arranged at the time of the big hit are even or odd, that is, the big hit winning probability in a normal game is set to 1/300, and the decorative symbol is set. If the same odd number (probably variable symbol) is stopped and displayed on the display screen of the display device 479 side by side, the probability variable lottery is won, and the probability until the next big hit winning is set to 1/30. On the other hand, if the same even numbers (normal symbols) are stopped and displayed side by side, the winning is not won in the probability change lottery, and the probability of the next big hit is set to 1/300. In such a gaming machine, the probability of the probability change symbol and the normal symbol appearing is uniform in the first starting winning device 431 and the second starting winning device 432, and the probability of the number giving the sub prize (that is, "1" among the odd numbers). , 3, 5, 7, 9 "or which of the even numbers," 2, 4, 6, 8 ") is changed by the first starting prize device 431 and the second starting prize device 432. The number displayed on the decorative symbol display device 479 may be determined by controlling the main control board 920 or may be determined by controlling the sub control board 940.

  In the above-described embodiment, a case has been described in which the sub prize lottery is executed only at the time of a small hit. The present invention is not limited to this, and it is also possible to execute a sub prize lottery in both a loss and a small hit. In this case, it is preferable to make the sub prize lottery probabilities different between the loss and the small hit. There is no limitation on the type, number and lottery probability of the supplementary prize, and the supplementary prize may be a special prize only, or three or more kinds of supplementary prizes may be provided. 0% or 100%, for example, a setting in which “7” is not selected at all, or a setting in which “7” is always selected as a winning number in the case of a small hit by the second starting winning device 432. A supplementary prize lottery including at least a selection based on a probability may be executed.

  In addition, as a result of the sub prize lottery, the value given to the player as the gaming machine 100 does not fluctuate. Specifically, a prize ball is specially given to the player or acquired according to the sub prize lottery result. It is preferable that the number of prize balls to be played does not change. That is, it is preferable that the supplementary prize does not relate to the operation of the device related to the payout of the prize ball including the special winning device 433, but merely differs from the display content of a part of the gaming machine 100 including the decorative symbol display device 479. The sub prize lottery may be executed by control of the main control board 920, or may be executed by a control board (for example, the sub control board 940) different from the main control board 920. For example, when a "small hit" is won as one lottery result by the main control board 920, a combination of symbols of "small, small, 7" is displayed by controlling the sub control board 940 based on the winning. It is good also as what carries out the lottery of the supplementary prize.

  In the above-described embodiment, a case has been described in which the downflow hole 63c is provided as a part of the clune 63 on the taxiway. The present invention is not limited to this, and the clune 63 is not necessarily indispensable, as long as a hole through which a game ball can flow down is formed on the taxiway.

  Further, in the above-described embodiment, a case has been described in which the movable bridge 70 is rotated by the rotation operation of the bridge connection motor 462 driven by the motor. The present invention is not limited to this, and the configuration of the movable bridge 70 is not limited, and a known structure can be appropriately selected and used. In addition, the movable bridge 70 can transition to a connected / non-connected state by sliding movement in the left-right direction instead of a rotating operation.

  Furthermore, in the above-described embodiment, a case has been described in which the rotational speed of the movable bridge 70 is not uniform. The present invention is not limited to this, and the rotating operation may always be performed at a constant speed. Further, it is not always necessary to maintain the connection state for a certain period of time, and the operation to the non-connection state may be started immediately.

  Further, in the above-described embodiment, a case has been described in which the above-described approach probability changing mechanism is provided in the second starting winning device 432. The present invention is not limited to this. For example, an entry probability changing mechanism may be provided in the large winning device 433, a general winning device, or the like.

In the above-described embodiment, the movable bridge 70 supports the lower side of the game ball by the bottom surface 71b composed of a plurality of surfaces in the connected state, and moves the game ball to the entrance side of the second start winning device 432. Although the configuration has the ball receiving portion for guiding, it is not always necessary to configure the ball receiving portion by one or a plurality of surfaces. For example, a ball receiving portion having a structure in which a plurality of streak-like support portions are arranged at intervals along the direction in which game balls are guided is provided behind the front surface 71g of the movable bridge, and the second starting winning device 432 is provided. The ball receiving portion may be constituted by another structure such as guiding the game ball to the entrance side of the ball.
Further, the present invention may be applied to a gaming machine or the like of a type different from the above embodiment. For example, once a big hit is made, the gaming machine may be implemented such that the big hit expected value is increased until a big hit state occurs a plurality of times (for example, two or three times). Further, after the big hit symbol is displayed, the gaming machine may be implemented as a gaming machine which enters a special gaming state on condition that a ball wins in a predetermined area. Further, the present invention may be applied to an enclosed game machine in which balls circulate. Further, in addition to the gaming machines, the present invention may be implemented as various gaming machines such as an arrangement ball type pachinko and a sparrow ball.

[Inventive groups extracted from the above embodiments]
The features of the invention group extracted from the above embodiment will be described while showing effects and the like as needed. In the following, for ease of understanding, correspondence with the configuration in the above-described embodiment is appropriately shown in parentheses, but is not limited to the configuration in parentheses.

  As described above, a conventional typical gaming machine is provided with a variable prize device having an entry permitting arrangement for permitting a game ball to enter and an entry preventing arrangement for preventing a game ball from entering. The change in the state is realized by a change in the arrangement of the entry control member provided inside the variable winning device.

  As such a gaming machine, a plate-shaped entry control member is arranged in parallel with the game board, and a winning opening is closed by the entry control member. A configuration in which the upper end thereof is projected forward to take an entry permitting arrangement, a game ball flowing down from above is received by an entry restricting member and guided to a winning opening, and a tongue piece extending in the front-rear direction and the tongue piece An entry restricting member having a front plate vertically suspended at the front end of the game board is disposed at the back of the game board, and the winning opening is closed by the front plate. The game ball which flows down from above is received by the entry restricting member, and is guided or drawn into the winning opening (for example, see Patent Document 1). Structure to block And the like.

  In the case of the conventional typical gaming machine, the game ball cannot enter the winning opening in the entry preventing arrangement, and the game ball is almost certainly guided to the winning opening in the entry allowable arrangement, Since the movement was simple, it was possible to fire the game ball aiming at the entry allowable arrangement, and the fairness as a game device was insufficient. Further, if it is possible to recognize whether or not the player is guided to the winning opening depending on whether the player is guided to the winning opening depending on whether the player is guided to the winning opening or not, it is not possible to sufficiently attract the interest of the player. Therefore, in order to attract the interest of the player and maintain the expectation and excitement, it is necessary to make the player clearly and clearly recognize whether or not the game ball is guided to the winning opening as late as possible. Desirable.

  In addition, although such a gaming machine is designed so that the gaming machine is installed at a correct inclination angle, there is little motivation to set the inclination angle correctly for the game arcade side, and according to the set value on the manufacturer side. It was difficult to set up a gaming machine in such a way.

  Further, in the start winning device having such an entry restricting member, the probability that the game ball can enter the winning opening is reduced as compared with the start winning device which does not have the entry restricting member, and the player feels unfair. I was embracing.

  In the variable winning device (starting winning device 450), from the viewpoint of clearly recognizing whether or not a game ball is guided to a winning opening, the following invention A group can be extracted, and the game ball is guided to the winning opening. From the viewpoint of allowing the player to recognize whether or not it is as late as possible, the following invention groups B and C can be extracted. In addition, the following invention D group can be extracted from the viewpoint of guiding game balls that have passed through a largely separated route to two winning ports arranged near each other.

<Invention A group>
Feature A1: a predetermined downstream portion (downflow hole 63c) provided in a ball guiding portion for guiding a game ball;
A prize guiding section (second starting guide path 54) that is arranged at a position deviated from immediately below the downstream part and guides the game ball to a predetermined prize section;
A front portion (movable bridge front surface 71g) that can be arranged in a direction substantially parallel to a game area in which a game ball flows down in a predetermined connection state, and is provided continuously on the rear side in the connection state with respect to the front portion. A movable member (movable bridge 70) having a ball receiving portion (bottom surface 71b);
A drive unit (bridge connection motor 426) for driving the movable member,
The movable member is rotated in a substantially horizontal direction about the rotation axis so that, in the connected state, the ball receiving portion is located below the downflow portion in a state where the front portion faces the gaming machine front side. Is located, and the game ball is located in a state where the game ball can proceed to the winning guide portion, and in the non-connection state, the front portion is oriented in a direction different from the game machine front side compared to the connection state. Further, a relay space having a size that does not allow the game ball to be guided to the winning guide portion is formed below the downflow portion.

  In the case of a gaming machine having the feature A1, since the movable member performs a substantially horizontal rotating motion that is not provided in a conventional gaming machine, it is possible to attract the player's interest and the gaming ball is guided to the winning opening. It is possible to make the player clearly recognize whether or not.

  It is preferable that the “movable member” transitions from the non-connection state to the connection state by a movement from the front direction to the rear direction. This prevents the player from visually recognizing the falling state of the game ball on the ball receiving portion, thereby reducing discouragement of the player when the game ball cannot enter the winning guide portion due to a slight difference in timing.

  Further, the “game area” may be an area formed on the front of the game board and through which game balls flow. Further, the “front portion that can be arranged in a direction substantially parallel to the game region” may be a front portion that can be arranged in a direction in which a region in which the game region is formed is continuous. Further, the “front surface” of the “movable member” may be a front surface facing the player in the connected state instead of the front surface that can be arranged in a direction substantially parallel to the game area in the connected state. Alternatively, it may be a front portion facing the front side of the gaming machine in the connected state. The “state in which the front portion faces in a direction different from the gaming machine front side as compared to the connected state” means that the gaming machine only needs to face a direction shifted from the gaming machine front side compared to the connected state. This includes a state in which the front portion faces obliquely forward on the front side of the machine.

Feature A2: In a gaming machine having feature A1,
In the connection state, the front portion is positioned substantially parallel to the game board, so that the ball receiving portion is positioned directly below the downstream portion, while in the non-connection state, the front portion is positioned on the game board. Position it almost perpendicular to it.

A prize-side guiding section (opening right 18a) for guiding a game ball reaching a predetermined distribution section (flow-down opening 18) provided in the game area to a predetermined prize section side;
A non-winning confirmation section (opening left side 18b) for guiding a game ball that has reached the predetermined distribution section to a side that does not enter the predetermined winning section,
At least one of the winning-side guiding section and the non-prize-winning section has a shape in which a horizontal width along the game board surface in a plan view changes according to a position in a front-rear direction perpendicular to the game board surface. And
The rate at which the game balls reaching the predetermined distribution section progress to the predetermined winning section changes according to the inclination angle of the gaming machine.

  Conventional typical gaming machines are provided with a prize-winning device having an entry-permitting arrangement for permitting the entry of game balls and an entry-preventing arrangement for preventing the entry of game balls, and a change in the permissible state of the prize-winning device. This is realized by a change in the arrangement of the entry control member provided inside (for example, see Japanese Patent Application Laid-Open No. 2007-319361).

  By the way, such a game machine is designed to be installed in a game hall (hall) at a correct inclination angle. For this reason, if all or a part of the gaming machine is installed at an inclination angle that is significantly different from the design value in the amusement arcade, the performance of the gaming machine, such as the probability of winning a prize device, greatly differs from the design value on the manufacturer side. As a result, there is a problem that the game arcade or the player may be disadvantaged.

  If the gaming machine has the feature E1, it is possible to provide a gaming machine that can easily detect that the maker is out of the tilt angle set by the manufacturer. That is, if the gaming board is not correctly set to the designed inclination angle, the gaming ball will not be guided to the predetermined winning section with the probability as designed. For this reason, it can be easily detected that the maker side is out of the set inclination angle based on the ratio of the game balls winning the predetermined winning section. Further, it is possible to provide a motivation for setting the gaming machine at the correct inclination angle on the gaming side. As a result, the gaming machine can be easily installed at an angle of inclination such that the design value is set by the manufacturer.

The number of game balls guided to a predetermined winning section increases. Therefore, it is possible to more easily detect that the maker side is out of the set inclination angle based on the ratio of the game balls winning the predetermined winning portion. Further, the motivation to set the gaming machine at the correct inclination angle on the gaming site side can be further increased.

  In addition, as the width of the winning-side guiding portion in plan view, it is preferable that the width in the rear portion of the gaming machine is set smaller than the radius of the gaming ball, and that the width in the front portion of the gaming machine is set larger than the radius of the gaming ball. Thus, it is possible to greatly change the probability that the game ball enters a predetermined winning section in accordance with the inclination angle of the gaming machine installed in the game arcade.

Feature E3: In a gaming machine having feature E1 or E2,
The non-winning confirmation section is provided adjacent to the winning opening, and the width in a plan view changes in a direction opposite to the winning opening in accordance with the position in the front-rear direction, and the predetermined distribution section Is guided to the discharge port (discharge port 401A) side.
