The gist is that when the driving means opens the opening / closing member, the opening / closing member guides the game ball flowing down from the upstream side of the specific entrance to the specific entrance.

The gaming machine of this reference invention includes an opening / closing member capable of opening and closing the specific entrance and a movable guiding portion provided on the front surface of the opening / closing member, and when the opening / closing member is in a closed state, the movable guiding portion is When the game ball that has flowed down from the upstream side of the specific entrance is directed toward a predetermined target downstream of the specific entrance, and the open / close member is open, the open / close member The game ball that has flowed down from the upstream side of the ball opening is guided to the specific entrance. Thereby, since the movable guide part for guiding the game ball to the predetermined target can be provided in the opening / closing member, the number of the guide members to be arranged on the game board as compared with the case where the guiding member is provided separately from the opening / closing member. It is possible to reduce the space required for the arrangement of the guide member. For this reason, it can suppress that problems, such as restrictions of arrangement of other members, such as a decoration member on a game board, and various entrances, arise. In addition, with a simple configuration in which the movable guide portion is simply provided on the front surface of the opening / closing member, it is possible to open and close the specific entrance and to guide the game ball when the specific entrance is closed. As a result, it is possible to open and close the specific entrance and guide the game ball to a predetermined target with a simple configuration in which the number of components placed on the game board is suppressed.

  Here, the “predetermined target” to which the game ball is guided refers to a start port (open / closed start port or non-open / closed start port) where a lottery for executing a big hit game is performed based on the entrance of the game ball. May be included), or may be an outlet for discharging game balls. Further, “opening / closing the opening / closing member” may mean rotating about any side of the opening / closing member, or sliding the opening / closing member up / down, left / right, or forward / backward. In addition, “upstream side” or “downstream side” includes a case of simply being on the high position side and a low position side, and a case of being on the upstream side and the downstream side in the flowing down direction (traveling direction) of the game ball.

In the gaming machine of such a reference invention, the opening / closing member is constituted by an opening / closing plate that rotates the end portion as an axis to open or close the specific entrance, and the front of the opening / closing member A movable guiding portion is provided, and a ball entrance guiding portion is provided on the rear surface of the opening / closing member. When the driving means closes the opening / closing member, the opening / closing member is raised, and the movable guiding portion However, when the game ball that has flowed down from the upstream side of the specific entrance is directed toward the predetermined target downstream of the specific entrance, and the driving means opens the opening and closing member, The opening / closing member is tilted, and the entrance entrance guiding unit guides the game ball flowing down from the upstream side of the specific entrance to the specific entrance.

  Here, since the movable guide portion is fixedly provided on the front surface (front surface) of the opening / closing plate, when the rotating operation (opening / closing operation) is performed about the end portion (lower end portion) of the opening / closing plate, the rotating operation is interlocked. To do. When the opening / closing plate is in the closed state (standing state), the inclined surface of the movable guiding portion is in a substantially horizontal state, and the flowing game ball is directed toward a predetermined target (another entrance or out port). Inducible state. In addition, when the opening / closing plate rotates from the closed state (standing state) to the open state (tilted state), the entrance guide provided on the rear surface (back surface) of the opening / closing plate becomes substantially horizontal and flows down. The ball can be guided into the specific entrance. At this time, the movable guiding portion tilts in conjunction with the opening operation of the opening / closing plate, and the inclined surface changes from a substantially horizontal state to a substantially upright state. In addition, the movable guide portion and the opening / closing plate are integrated, but may be integrally formed, or may be a separate member and fixed by a fixing member such as a screw. In addition, the entrance guide part may be provided by attaching a dedicated member to the rear surface of the opening / closing plate, or may be provided using the rear surface of the opening / closing plate.

In the gaming machine according to the reference invention of this aspect, the identification may be performed by causing the entrance guide portion to protrude forward with respect to the board surface of the game board by rotating the lower side of the open / close plate in the closed state as an axis. The entrance may be in the open state, and the entrance entrance guiding unit may guide the game ball that has flowed down from the upstream side of the specific entrance to the specific entrance. In this way, when the specific entrance is in an open state, the game ball received by the movable guide portion formed on the back surface of the opening / closing plate is smoothly blocked without being blocked by the movable guide portion provided on the opening / closing plate. Can lead to the mouth.

Further, in the gaming machine of the reference invention, the lateral width of the opening / closing plate is formed to be a lateral width capable of opening or closing the specific entrance, and the lateral width of the inclined surface of the movable guiding portion is It can also be formed in a length exceeding the lateral width of the opening / closing plate. In this way, regardless of the size of the specific entrance (even if the lateral width of the specific entrance and the opening and closing plate is small), in a range wider than the lateral width of the specific entrance (wider flow of game balls) A game ball can be guided (by width).

Furthermore, in the gaming machine of the reference invention, when the launching device that launches the game ball is operated by the player in the first mode, the game ball that is launched from the launching device and flows down the game area can enter the game machine. A first start port arranged and configured to be able to switch between a state in which the entrance is configured to be constant and a state in which the entrance is easy to enter a game ball and a state in which entry is difficult. And a winning lottery based on a game ball entering the first starting port or the second starting port, and a hit game for opening and closing the specific entrance based on the result of the corresponding lottery. A game execution means; and a specific game execution means for executing a specific game that brings the second start port in an advantageous state for a player after the winning game is completed until a predetermined end condition is satisfied, The entrance is the second different in the launching device from the first aspect. The movable guiding portion is formed at a position where the game ball can enter when operated by the player in the aspect, and the inclined surface is inclined with the second starting port as the predetermined target. It can also be. In this way, the player only has to operate the launching device in the second mode until the specific game is completed from the hit game, so that the operation mode is compared with the one in which the mode of operation changes frequently. This aspect can be easily understood by the player.

  Here, the “first mode” and the “second mode” are different in the mode of operation of the shooting device by the player (for example, the amount of rotation of the shooting operation unit is different). It is possible to vary the firing strength of the launching device and to make the arrival point of the launched game ball differ between when operated in the first mode and when operated in the second mode.

  According to the gaming machine of the present invention, the number of components placed on the gaming board is suppressed and the space on the gaming board is effectively utilized, and the opening and closing of the entrance and the guidance of the gaming ball to a predetermined target are performed with a simple configuration. And can be done.

  The big prize opening 44 is formed as a rectangular opening in the big prize opening unit 50 incorporated in the game board 30. FIG. 4 shows the appearance of the big prize opening unit 50 with the big prize opening 44 closed, and FIG. 5 shows the appearance of the big prize opening unit 50 with the big prize opening 44 open. FIG. 2 shows a front view of the special prize opening unit 50. The big prize opening 44 is normally closed by the opening / closing plate 55 of the big prize opening unit 50 so as not to accept a game ball (see FIGS. 4 and 6A). The open / close plate 55 is actuated by 44b (see FIG. 3) so as to be opened (see FIG. 5 and FIG. 6 (b)). In addition, a large winning opening switch 44a (see FIG. 3) for detecting winning of a game ball and counting the number of winning is attached to the large winning opening 44. In the present embodiment, as a process for the big hit game, one big round is taken until a predetermined time (for example, 25 seconds) elapses before the big winning opening switch 44a counts ten game balls or counts ten. The winning opening 44 is opened, and the opening operation of the large winning opening 44 is repeated until the prescribed round. Between each round, the special winning opening 44 is closed for a predetermined time (for example, 2 seconds).

  The special winning opening unit 50 includes a unit main body 51 that houses a special winning opening switch 44a, a special winning opening solenoid 44b, and the like, and a front plate 54 that is attached to the front surface of the unit main body 51. The unit main body 51 connects an inclined plate 52 inclined so as to collect the game balls won in the rectangular large winning opening 44 at one end side, and one end side of the large winning opening 44 and a transport path for collecting the game balls (not shown). A communication path 53 through which a game ball won in the big prize opening 44 passes is formed. The big prize opening switch 44 is provided in the middle of the communication path 53 (see FIG. 5), and by detecting a game ball passing through the communication path 53, the winning of the game ball to the big prize opening 44 is achieved. Is detected.

  The front plate 54 is a wide flat plate. A rectangular opening 54a having a prescribed size is formed at the approximate center, and a total of four through holes 54b are formed at the four corners. When the front plate 54 is screwed into a screw hole (not shown) formed in the game board 30 through the through hole 54b, the big prize opening unit 50 (front plate 54) is fixed to the game board 30, and the front plate 54 The opening 54a is in a state along the board surface of the game board 30 and functions as the big prize opening 44. The opening / closing plate 55 is a rectangular flat plate formed in a size matching the opening 54 a (large winning opening 44) so that the opening 54 a (large winning opening 44) can be just closed, and on the surface of the game board 30. It becomes a closed state in which the opening 54a (big winning opening 44) is closed in parallel with each other (a gap that prevents a game ball from entering in the closed state may be open). For this reason, the surface of the opening / closing plate 55 that is the front side (front side) of the game board 30 in the closed state is referred to as a closed surface 55a. The closing surface 55a of the opening / closing plate 55 is formed with an inclined surface 57a inclined downward from the right side to the left side when the game board 30 is viewed from the front, and is movable relative to the gaming board 30 in conjunction with opening / closing of the opening / closing plate 55. A flat plate-shaped movable guide plate 57 is provided. The movable guide plate 57 is formed such that the inclined surface 57 a exceeds the size (width, width) of the opening / closing plate 55 and extends over substantially the entire width of the front plate 54. Further, the open / close plate 55 is rotatably attached to the front plate 54 by a shaft 56 provided at a position on the lower side (the position of the lower end of the opening 54a) in the closed state. ) Is rotated about the shaft 56 to move away from the opening 54a (large winning opening 44), thereby opening the large winning opening 44 (open state) and closing the opening 54a (large winning opening 44). Then, the special winning opening 44 is closed (closed state). When in the open state, the opening / closing plate 55 protrudes forward from the board surface of the game board 30, the closing surface 55a of the opening / closing plate 55 faces downward, and the back surface 55b (rear surface) opposite to the closing surface 55a is upward. Will turn to. At this time, the rotation range of the opening / closing plate 55 (shaft 56) is such that the back surface 55b is slightly inclined downward (from the front side to the back side in FIG. 5) toward the special winning opening 44 side. It was decided. For this reason, the back surface 55b of the opening / closing plate 55 in the open state functions as a game ball guiding portion (entrance port guiding portion) that receives the game balls flowing down from the upstream side and guides them to the big winning opening 44 (wins). Become. When the opening / closing plate 55 is in the open state, the closing surface 55a faces downward, so that the movable guide plate 57 provided on the closing surface 55a does not exhibit the gaming ball guiding function.

  Since the big prize opening unit 50 is configured in this way, the flow of the game ball is as follows. Here, let us consider the flow of game balls that are fired by so-called right hitting, in which a player turns the launch handle 18 clockwise to the maximum to fire a game ball. The game ball launched by the right strike flows down the right side area of the game area 31 of the game board 30 and is guided by a fixed decorative member 37 (see FIG. 2) disposed on the game board 30 or a nail not shown. It flows down the upstream side of the big prize opening 44. At this time, if the opening / closing plate 55 is in a closed state (the big winning opening 44 is in a closed state), the movable guide plate 57 (inclined surface 57a) protrudes forward from the board surface of the game board 30 (the opening / closing plate 55). The game ball flowing down the upstream side of the big prize opening 44 is guided from the right side to the left side along the inclined surface 57a when it reaches the movable guide plate 57. (Arrow in FIG. 4). That is, the movable guide plate 57 exhibits a game ball guiding function. Here, as shown in FIG. 2, since the second starting port 38 is provided on the downstream side of the left side of the big winning port 44, the movable guide plate 57 (inclined) flows down the upstream side of the big winning port 44. The game ball guided by the surface 57a) is guided to the second starting port 38 on the downstream side of the big winning port 44. If the opening / closing plate 55 is in the open state (the big winning opening 44 is in the open state), the opening / closing plate 55 protrudes forward with respect to the board surface of the game board 30, and the movable guide plate 57 functions to guide the game ball. Therefore, when the game ball flowing down the upstream side of the big winning opening 44 reaches the opening / closing plate 55, it will win the big winning opening 44 along the back surface 55b (arrow in FIG. 5). As described above, the opening / closing plate 55 has a function of opening / closing the special winning opening 44, and the movable guide plate 57 has a function of guiding the game ball to the second starting port 38. The combination with 57 is referred to as an opening / closing guide 58.

  As illustrated in the configuration diagram of FIG. 7, the symbol display device 40 includes a normal symbol display device 41 capable of displaying and changing a normal symbol and a special symbol display device capable of displaying and changing a special symbol. 42. The normal symbol display device 41 includes a left normal symbol display unit 41a and a right normal symbol display unit 41b configured using light emitting diodes (LEDs). In FIG. 8, an example of the display mode of the normal symbol display device 41 is shown. As shown in FIG. 8, the normal symbol display device 41 has a display mode in which both the left normal symbol display unit 41a and the right normal symbol display unit 41b are turned off (see the first stage from the top in FIG. 8), and the left normal symbol display unit 41b. Display mode in which the display unit 41a is turned on and the right normal symbol display unit 41b is turned off (see the second row from the top in FIG. 8), and the display mode in which the left normal symbol display unit 41a is turned off and the right normal symbol display unit 41b is turned on (Refer to the third row from the top in FIG. 8) and four display modes in which both the left normal symbol display portion 41a and the right normal symbol display portion 41b are lit (see the fourth row from the top in FIG. 8). There is. When the normal symbol display device 41 detects that the game ball passes through the normal symbol operation gate 32, the normal symbol display device 41 performs variable display by sequentially switching the four display modes. The display is stopped in one of the display modes. At this time, when the display mode stopped and displayed is a specific display mode (for example, the display mode shown in the fourth row from the top in FIG. 8), the ordinary electric accessory 39 is held for a certain period of time (for example, 0. 0). For 5 seconds). When the game ball passes through the normal symbol operation gate 32 during the normal symbol fluctuation display, the normal symbol fluctuation display is held up to four times, and when the current fluctuation display ends, it is held. The variable display is digested sequentially.

  As shown in FIG. 7, the special symbol display device 42 includes a first special symbol display unit 42 a and a second special symbol display unit 42 b configured using a seven-segment display. A special symbol is expressed in a plurality of display modes (up to 128) in combination with turning off. The special symbol display device 42 variably displays the special symbol by sequentially switching the display state when winning to the first start port 36 or the second start port 38 is detected, and when the execution time of the variable display has elapsed. The special symbol is stopped and displayed in any one of the display modes that can be expressed. At this time, when the display mode of the special symbol that is stopped and displayed is a specific display mode, the big winning opening 44 is opened for a certain time (for example, 25 seconds) as a big hit. In the embodiment, the first special symbol display unit 42a is a display unit for the first start opening winning that displays the special symbol when the game ball is won in the first starting port 36, and the second special symbol display unit 42b is The display part for the second start opening winning a prize that variably displays the special symbol when the game ball wins the second start opening 38 is used. Hereinafter, in particular, the special symbol displayed on the first special symbol display unit 42a for winning the first start opening is also referred to as the first special symbol, and is displayed on the second special symbol display unit 42b for winning the second starting port. This special symbol is also called a second special symbol. That is, when the ball enters the first start port 36, the first special symbol is variably displayed. When the ball enters the second start port 38, the second special symbol is variably displayed. In FIG. 9, an example of the display mode of the special symbol display device 42 at the time of big hit is shown. As shown in the drawing, the special symbol (the first normal big hit symbol) that becomes the first normal big hit is the display mode in which the upper right, lower right, and lower left vertical bar segments in the first special symbol display section 42a are lit. 2 There are display modes in which the middle horizontal bar segment and the upper right and lower left vertical bar segments in the special symbol display section 42b are lit (see the first row from the top in FIG. 9). In addition, the special symbol (first probability variable big hit symbol) that becomes the first probability variation big hit is a display mode in which the upper horizontal bar segment and the lower right and lower left vertical bar segments in the first special symbol display section 42a are lit. There is a display mode in which the upper horizontal bar segment and the upper left and lower left vertical bar segments in the second special symbol display section 42b are lit (see the second level from the top in FIG. 9). The special symbol for the second probability variation big hit (second probability variation big hit symbol) is a display mode in which the upper horizontal bar segment and the lower right vertical bar segment in the first special symbol display unit 42a are lit, and the second special symbol There is a display mode in which the upper and lower horizontal bar segments and the lower left vertical bar segment in the symbol display section 42b are lit (see the third level from the top in FIG. 9). In addition, the display mode of the special symbol at the time of the big hit is not limited to the above mode, and may be displayed in any manner, and the type of the display mode of the special symbol at the time of each big hit is not limited to one type, A plurality of types may be prepared. When the game ball wins either the first start port 36 or the second start port 38 during the special symbol variation display, the special symbol variation display is suspended for a maximum of four times for each start aperture. When the change display of is finished, the change display of the special symbol that is put on hold is sequentially digested. As will be described later, the number of holdings of the variable display of the first special symbol is displayed by the first holding symbol 35a, and the number of holdings of the variable display of the second special symbol is displayed by the second holding symbol 35b.

  Here, in the first normal jackpot, a jackpot game in which the opening operation of the big winning opening 44 is repeated over a predetermined number of rounds (for example, 15 rounds) is performed, and a predetermined number of times (for example, after the jackpot game ends) , 100 times) until the special symbol variation display is performed, the variation time of the special symbol and the normal symbol is shortened, and when the normal symbol is stopped and displayed, the opening time of the ordinary electric accessory 39 is extended. It is a big hit mode that becomes a state (so-called short-time state). In addition, after the big hit game related to the first normal big hit, the low probability state (also referred to as a low probability mode) where the probability of the big hit determination result is a big hit is low. As in the first normal jackpot, the first winning jackpot game is a jackpot game in which the opening operation of the jackpot 44 is repeated for a predetermined number of rounds (for example, 15 rounds), and after the jackpot game ends. This is a big hit mode in which a probability change state (also referred to as a high probability mode) in which the probability of the big hit determination is higher than that in the low probability mode becomes a time-short state until the big hit is drawn. In addition, in the second probability variation jackpot, a jackpot game in which the opening of the big winning opening 44 is repeated over a smaller number of rounds (for example, two rounds) than the first normal jackpot is performed, and after the jackpot game is over This is a big hit mode in which a probabilistic state and a short time state are obtained until the next big hit is drawn. In this embodiment, at the start of the big hit game, a round display unit 43 for displaying a symbol indicating the maximum number of rounds of the big hit game is provided in a part of the symbol display device 40 (see FIG. 7). The round display unit 43 is configured by using a 7-segment display similarly to the first special symbol display unit 42a and the second special symbol display unit 42b. The display mode of the round display unit 43 includes a display mode in which the upper and middle horizontal bar segments and the upper left and lower left vertical bar segments are lit (in the form of the letter “F”), and the upper display in the round display unit 43. , Middle and lower horizontal bar segments and upper right and lower left vertical bar segments are lit (lighted in the form of “2” in arithmetic numbers). The former display mode is “first normal jackpot” ”And“ first probability variation jackpot ”as a trigger, and the latter display mode corresponds to a jackpot game round number display as a trigger of“ second probability variation jackpot ”.

  The effect display device 34 is configured as a display device such as a liquid crystal display, and displays various fluctuating effects such as a fluctuating display of effect symbols, a reach effect, and a notice effect on the display screen. As shown in the screen configuration illustrated in FIG. 10, the display screen of the effect display device 34 has three effect symbols (pseudo special) arranged side by side and composed of characters, numbers, and the like. 34L, 34M, and 34R (also called symbols or pseudo symbols) and background symbols (not shown) are displayed. The effect symbols 34L, 34M, and 34R are variably displayed when the game ball wins the first start port 36 or when the game ball wins the second start port 38, and the effect symbols 34L, 34M, and 34R are displayed. The change display and the stop display are performed in conjunction with the change display and the stop display of the first special symbol or the second special symbol. When the variation display is started, the effect symbols 34L, 34M, and 34R are variably displayed so as to scroll at high speed from the top to the bottom, and the execution time of the variation display (predetermined variation display time) has elapsed. Then, the display is stopped and displayed in the order of the left effect symbol 34L, the right effect symbol 34R, and the middle effect symbol 34M. At this time, when none of the three effect symbols 34L, 34M, and 34R match (when all three symbols are different from each other), it becomes a simple release without reach (for example, “231”), and the effect symbol on the left Reach is reached when 34L and right performance symbol 34R coincide. When the middle production symbol 34M stops with a predetermined reach production and the middle production symbol 34M and the left and right production symbols 34L and 34R do not match, it is determined that the reach is off (for example, “353”). ]), When the middle production symbol 34M and the right and left production symbols 34L and 34R coincide, a big hit is obtained (for example, “777”). The result of the success or failure of the effect symbol displayed on the effect display device 34 is basically the result of the success or failure of the special symbol (first special symbol or second special symbol) displayed by the special symbol display device 42 described above. Matches.

  In the present embodiment, the first reserved symbol 35 a and the second reserved symbol 35 b are also displayed in the display screen of the effect display device 34. The first reserved symbol 35a is displayed one by one in order from the left whenever a game ball is won at the first starting opening 36 during the variation display of the first special symbol or the second special symbol, and the variation display of the first special symbol Each time is started, it is erased one by one in the order of the winning prizes (in order from the retained symbols corresponding to the old retained information). The second reserved symbol 35b is displayed one by one in order from the left whenever a game ball is won at the second starting opening 38 during the variation display of the first special symbol or the second special symbol, and the variation display of the second special symbol Each time is started, it is erased one by one in the order of the winning prizes (in order from the retained symbols corresponding to the old retained information).

  In the pachinko machine 10 of the embodiment configured as described above, the first start port 36 is arranged below the center accessory 33, and the player can play the game ball in the game area 31 during a normal game that is not a big hit game. By rotating the firing handle 18 so as to flow down to the left (so-called left-handed), the game ball can be won at the first start port 36. In addition, the second start port 38 is disposed below the first start port 36, and in the short-time game (specific game), the player can make a second game ball by hitting left or right. The start opening 38 can be awarded. However, as described above, the movable guide plate 57 is provided on the closing surface 55a of the opening / closing plate 55 that opens and closes the grand prize winning port 44, and the game ball is moved to the second starting port 38 when the special prize winning port 44 is closed. Since guidance is possible, the player can efficiently win the game ball at the second start opening 38 when the player hits the right side rather than the left side. The big prize opening 44 is arranged in the lower right part of the game area 31. When the big hit game is started, the player hits the right to cause the game ball to flow down to the right side of the game area 31 and win the big prize opening 44. Can be awarded.

[Configuration of control circuit]
Next, the configuration of the control circuit of the pachinko machine 10 of the embodiment will be described with reference mainly to FIG. As shown in FIG. 3, the control circuit of the pachinko machine 10 includes a main control board 70 that controls the basic progress of the game, a payout control board 80 that controls the payout of prize balls and ball rentals, The control board includes a sub-control board 90 that controls the overall control of various effects performed along with the progress, and a control board such as a launch control board 100 that controls the game ball. These control boards include a CPU that executes various logical operations and calculation operations, a ROM that stores various programs and data executed by the CPU, a RAM that temporarily stores data when the programs are executed, peripheral devices, Peripheral device interface (PIO) for exchanging data between them, an oscillator that outputs a clock for the CPU to perform operations, a watchdog timer for monitoring CPU runaway, and a CTC (counter that periodically generates interrupt signals) Various peripheral LSIs such as a timer circuit are connected to each other by a bus. In FIG. 3, only the CPU 70 a, ROM 70 b, and RAM 70 c of the main control board 70 among the various devices mounted on each control board are shown, and the other parts are not shown. Here, FIG. 11 is a block diagram showing an outline of the configuration of the sub-control board 90 forming a part of the control circuit.

  As shown in FIG. 3, the main control board 70 receives signals from the first start port switch 36a and wins from the second start port switch 38a as signals necessary for controlling the basic progress of the game. A signal is directly input, and a passing signal from the gate switch 32a, a winning signal from the big winning opening switch 44a, a winning signal from the general winning opening switch 45a, and the like are input through the relay terminal plate 72. From the main control board 70, a control signal to the symbol display board 40 a that controls display of the symbol display device 40, a drive signal to the ordinary electric accessory solenoid 39 b, a drive signal to the big prize opening solenoid 44 b, etc. are relay terminal boards 72 is output. The main control board 70 communicates with the payout control board 80, the sub control board 90, and the launch control board 100 (communication via the payout control board 80), and various command signals (commands, drive signals, etc.) and data. We are exchanging.

  As shown in FIG. 3, the payout control board 80 directly receives a detection signal from a frame opening switch 81 for detecting the opening of the front frame 11 as a signal necessary for performing control related to payout of award balls and ball rentals. The operation signals from the ball lending button 24a and the return button 24b are input via the ball lending display board 82 and the relay terminal board 83, and are received from the pre-payout switch 84 and the post-payout switch 85 for detecting the payout of the prize ball. A detection signal is input via the relay terminal board 87. From the payout control board 80, a drive signal to the payout motor 86 for paying out the prize balls is output via the relay terminal board 87. The payout control board 80 communicates with the main control board 70 and the launch control board 100, and exchanges various command signals and data.

  As shown in FIG. 11, the sub control board 90 includes a CPU 90a, a ROM 90b, a RAM 90c, etc., and receives various command signals from the main control board 70 and produces a game according to the commands. The sub control board 90 drives an effect display control board 91 that controls the effect display device 34, an amplifier board 92 that drives the various speakers 28a and 28b, various LED lamps 93a, and operates a movable decorative member. A decoration drive board 93 for driving the decoration motor 93b, an effect button board 94 for inputting an operation signal from the effect button 26, and the like are connected.

  The firing control board 100 detects a detection signal from the touch sensor 18a, an operation signal from the firing stop switch 18b, a detection signal from the lower tray full switch 102 that detects that the game ball is full in the lower tray 16 and the like. And a pulse signal for driving is output to the firing motor 19. The launch control board 100 drives the launch motor 19 to launch a game ball when the launch handle 18 is rotated, the touch sensor 18a is on, the launch stop switch 18b is off, and the lower tray full switch 102 is off. When either the touch sensor 18a is turned off, the firing stop switch 18b is turned on, or the lower tray full tank switch 102 is turned on, the driving of the firing motor 19 is stopped and the launch of the game ball is stopped. Further, the launch control board 100 communicates with the main control board 70 via the payout control board 80, and data regarding the operation state of the launch handle 18 such as a detection signal from the touch sensor 18 a is sent via the payout control board 80. Transmit to the main control board 70.

[Main control processing]
Next, the operation of the pachinko machine 10 according to the embodiment thus configured will be described. FIG. 12 is a flowchart illustrating an example of a main control process executed by the CPU 70a of the main control board 70. This process is executed when the power of the pachinko machine 10 is turned on. The main control process executes a power-on process necessary for power-on such as an initialization process (step S100), a game start process (step S110), a normal symbol game process (step S120), and a game per normal symbol This is performed by repeatedly executing the process (step S130), the special symbol game process (step S140), and the big hit game process (step S150). In the present embodiment, the time required for the processes of steps S110 to S150 is about 4 msec, and therefore these processes are repeatedly executed at intervals of about 4 msec. The main control board 70 advances the entire game of the pachinko machine 10 by transmitting various commands to the control board in charge and executing the processes according to the commands in accordance with the execution of these processes.

[Game start processing]
In the game start process of step S110, the CPU 70a of the main control board 70 first starts various sensors (gate switch 32a, first start port switch 36a, second start port switch 38a, big winning port switch 44a, general winning port switch 45a. Etc.) and stored in a predetermined state storage area of the RAM 70c, or update various random number values (such as jackpot determination random numbers, jackpot symbol determination random numbers, reach random numbers, fluctuation pattern determination random numbers, etc. described later). To do. Subsequently, it is determined whether or not a game ball is detected by a switch related to winning a game ball (such as the first start port switch 36a, the second start port switch 38a, and the big winning port switch 44a). The prize ball to be paid out is calculated and saved as prize ball information in a predetermined prize ball information storage area of the RAM 70c. When the prize ball information is not 0, a prize ball designation command (prize ball information) is sent to the payout control board 80. The game start process is completed. When the payout control board 80 receives the prize ball designation command, the payout motor 86 is driven and controlled to pay out the game balls one by one, and at the same time, the game balls paid out by the pre-payout switch 84 and the post-payout switch 85 are detected. Then, a prize ball payout process for decrementing the prize ball information (the number of unpaid game balls) by 1 is executed. This award ball payout process is repeatedly executed until the award ball information reaches a value of 0. However, when a winning game ball is detected and a new award ball designation command is received from the main control board 70, the award ball information is also displayed. The process is repeated until the value becomes zero. When the game start process ends, the process returns to the main control process and proceeds to the normal symbol game process of the next step S120.

[Normal design game processing]
In the normal symbol game process of step S120, the CPU 70a of the main control board 70 first determines whether or not the normal symbol hold is not the value 0, that is, whether the value is 1 or more. Decrement the number by 1 to determine whether or not the normal symbol is appropriate, and determine the normal symbol to be stopped and displayed based on the result of the determination. The normal symbol success / failure determination is performed using a normal symbol per symbol determination table for low probability when the time probability is not short (for example, about 0.8%), and when the time is short, the probability is high ( For example, about 99.2%) is performed using a normal symbol determination table for high probability. Further, when the result of the determination is successful, the winning design (see the fourth row from the top in FIG. 8) is determined to be stopped and displayed, and when the result of the determination is out of the way (from the top in FIG. 8). 1 to 3) is determined as a symbol to be stopped and displayed. Then, the normal symbol fluctuation display time is set to start the normal symbol fluctuation display, and waits until the fluctuation display time elapses. The variable display time is set to a long time (for example, 30 seconds) when not in the short time state, and is shortened to a short time (for example, 1 second) when in the short time state. When the variable display time elapses, the normal symbol is stopped and displayed with the determined symbol, and when the stopped and displayed symbol is the winning symbol, the opening time of the ordinary electric accessory 39 is set and the opening of the ordinary electric accessory 39 is started. The normal symbol game process is temporarily terminated, and when the stopped and displayed symbol is out of the symbol, the normal symbol game process is terminated without doing anything. The opening time of the ordinary electric accessory 39 is set to a short time (for example, 0.5 seconds) when not in the short time state, and is extended to a long time (for example, 5 seconds) when in the short time state. As described above, the ordinary electric accessory 39 is opened by controlling the drive of the ordinary electric accessory solenoid 39b to open the pair of wing piece portions 39a to the left and right. At this time, if the special winning opening 44 is in the closed state, the game ball flowing down the right side of the game area 31 can be guided to the second starting port 38 by the movable guide plate 57 (inclined surface 57a). A game ball can be won efficiently at the start port 38. When the normal symbol game process ends, the process returns to the main control process and proceeds to the next normal symbol game process in step S130.

[Game processing per normal symbol]
In the normal symbol game process of step S130, the CPU 70a of the main control board 70 sets the elapsed time (open elapsed time) from the start of the normal electric accessory 39 to the set time set in the normal symbol game process. It is determined whether or not a predetermined number (e.g., eight) of game balls has won the second start opening 38. If it is determined that the opening elapsed time has not reached the set time and the specified number of game balls have not won the second starting port 38, the normal electric game 39 is temporarily released while the normal electric accessory 39 is kept open. finish. On the other hand, if it is determined that the elapsed elapsed time has reached the set time, or if it is determined that a specified number of game balls have already won the second start opening 38 even before the elapsed elapsed time has reached the set time. Then, the driving of the ordinary electric accessory 39 is stopped, and the game process per ordinary symbol is finished. When the normal symbol per game process is completed, the process returns to the main control process and proceeds to the special symbol game process of the next step S140.

[Special design game processing]
The special symbol game process of step S140 is executed according to the flowcharts shown in FIGS. When the special symbol game process is executed, the CPU 70a of the main control board 70 first inputs a detection signal from the first start port switch 36a to the first start port 36 for variably displaying the first special symbol. It is determined whether or not a game ball has been won (step S200). If it is determined that the game ball has won the first start opening 36, it is determined whether or not the current number of reserved special symbols is smaller than the upper limit value (value 4 in this embodiment) (step S202). . When it is determined that the number of reserved special symbols is less than the upper limit, the number of reserved special symbols is incremented by 1 (step S204), and a random number for determination is obtained to obtain a predetermined determination in the RAM 70c. Store in the random number storage area (step S206). In addition, when the number of holdings of the first special symbol is incremented in step S204, a command for displaying the number of holdings on the first holding symbol 35a of the effect display device 34 (holding number command of the first special symbol) or the like is sub-controlled. Transmit to the substrate 90. Here, as the determination random number acquired in step S206, when the big hit determination random number used in the big hit determination performed by winning the game ball to the first start port 36 or the result of the big hit determination is a big hit The special display random number for determining the jackpot symbol to be stopped and displayed on the first special symbol display unit 42a, and the reach display when the effect symbol is variably displayed on the display screen of the effect display device 34 because the result of the jackpot determination is out of place. For example, reach random numbers for determining whether or not to perform. If it is determined in step S200 that no game ball has been won in the first start opening 36, or if it is determined in step S202 that the number of first special symbols held has reached the upper limit, the processing in steps S204 and S206 is performed. Is skipped and the process proceeds to the next step S208.

  Subsequently, a detection signal from the second start port switch 38a is input to determine whether or not a game ball has won the second start port 38 for variably displaying the second special symbol (step S208). If it is determined that a game ball has won the second start port 38, it is determined whether or not the current number of reserved second special symbols is less than the upper limit value (value 4 in this embodiment) (step S210). . When it is determined that the number of reserved special symbols is less than the upper limit value, the number of reserved special symbols is incremented by 1 (step S212), and a random number for determination is obtained to obtain a predetermined determination in the RAM 70c. Store in the random number storage area (step S214). In addition, when the number of holdings of the second special symbol is incremented in step S212, a command for displaying the number of holdings on the second holding symbol 35b of the effect display device 34 (second special symbol holding number command) is sub-controlled. Transmit to the substrate 90. Here, as the determination random number acquired in step S214, when the big hit determination random number used in the big hit determination performed by winning the game ball to the second starting port 38 or the result of the big hit determination is a big hit The special display random number for determining the jackpot symbol to be stopped and displayed on the second special symbol display section 42b, the reach display when the effect symbol is variably displayed on the display screen of the effect display device 34 because the result of the jackpot determination is out of place. For example, reach random numbers for determining whether or not to perform. If it is determined in step S208 that no game ball has been won in the second starting port 38, or if it is determined in step S210 that the number of reserved special symbols has reached the upper limit, the processing in steps S212 and S214 is performed. Is skipped and the process proceeds to the next step S216.

  Next, whether or not a big hit game is being played (step S216), whether or not any of the first special symbol and the second special symbol is variably displayed (step S218), the first special symbol and the second special symbol It is determined whether any of the symbols is in the stop display time (step S220). If it is determined that the game is a big hit game, the special symbol game process is terminated, and the process returns to the main control process to proceed to the next big hit game process in step S150. On the other hand, if it is determined that neither the first special symbol nor the second special symbol is in the variable display, and neither the first special symbol nor the second special symbol is in the stop display time, it is not in the big hit game. It is determined whether or not the number of reserved 2 special symbols is 0 (step S222). If it is determined that the second special symbol hold number is not 0, the oldest determination random number among the second special symbol determination random numbers (big hit determination random numbers) stored in the random number storage area (RAM 70c) is read ( Step S224), the variable display related process shown in FIG. 16 is executed (Step S226), and the special symbol game process is temporarily terminated. On the other hand, if it is determined that the number of reserved special symbols is 0, it is determined whether or not the number of reserved special symbols is 0 (step S228). If it is determined that the first special symbol hold number is not 0, the oldest determination random number is read out from the first special symbol determination random numbers (big hit determination random numbers) stored in the random number storage area (RAM 70c) ( Step S230), the variable display related process is executed (Step S232), and the special symbol game process is temporarily terminated. When the number of holds for the first special symbol is also 0, the special symbol game process is terminated. In steps S222 to S232, when both the number of reserved first symbol symbols and the number of reserved second symbol symbols are not 0, the second special symbol variable display (holding digestion) is preferentially executed. Details of the variable display related process will be described below. The first special symbol variation display related process and the second special symbol variation display related process are both executed in common, and will be described with reference to a common flowchart (the flowchart of FIG. 16).

  In the variation display related process, first, it is determined whether or not the probability variation flag is on, that is, whether the current gaming state is the high probability mode or the low probability mode (step S300). When the probability variation flag is off, that is, when the current gaming state is in the low probability mode, the big hit determination is performed using the big hit determination random number read in step S224 or step S230 and the low probability big hit determination table (step S302), When the probability variation flag is on, that is, when the current gaming state is the high probability mode, a big hit determination is performed using the read big hit determination random number and the high probability big hit determination table (step S304), and the determination result is a big hit It is determined whether or not (step S306). An example of the big hit determination table is shown in FIG. FIG. 17A shows a low probability jackpot determination table, and FIG. 17B shows a high probability jackpot determination table. As shown in the figure, in this embodiment, the same jackpot determination table is used for the first special symbol and the second special symbol, and in the low probability jackpot determination table, the jackpot determination random number is a value from 0 to 796. The jackpot is set to 60 or 61 (a jackpot probability of 1 / 398.5), and the jackpot determination table for high probability is set to the jackpot when the hit determination random number is a value 60 to 79 out of the values 0 to 796. (Large probability of 1 / 39.85).

  When it is determined in step S306 that the result of the big hit determination is a big hit, the big hit symbol determination random number is read from the determination random number storage area (RAM 70c) (step S308), and the big hit symbol determination table is set (step S310). Then, the jackpot symbol to be stopped and displayed is selected and set using the set jackpot symbol determination table and the read jackpot symbol determination random number (step S312). Here, for determining the jackpot symbol of the first special symbol, the table for determining the jackpot symbol for the first special symbol illustrated in FIG. 18 is used. For determining the jackpot symbol of the second special symbol, FIG. The big special symbol determination table for the second special symbol illustrated is used. In the jackpot symbol determination table for the first special symbol, as shown in FIG. 18, when the jackpot symbol determination random number is a value 0 to 101 among the values 0 to 255, the symbol in the upper left of FIG. 9 is selected. “First normal big hit” (approximately 40% big hit distribution probability), when the big hit symbol determination random number is a value 102 to 203, the symbol in the middle left of FIG. 9 is selected and becomes “first probable big hit” (About 40% big hit distribution probability) When the big hit symbol determination random number is a value of 204 to 255, the lower left symbol of FIG. 9 is selected and becomes the “second probability variation big hit” (about 20% big hit distribution) probability). In addition, in the jackpot symbol determination table for the second special symbol, as shown in FIG. 19, when the jackpot symbol determination random number is a value 0 to 101 among the values 0 to 255, the symbol on the upper right in FIG. 9 is selected. 9 becomes the “first normal big hit” (approximately 40% big hit distribution probability), and when the big hit symbol determining random number is a value of 102 to 229, the right middle symbol of FIG. When the random number for determining the big hit symbol is 230 to 255, the lower right symbol in FIG. 9 is selected and becomes the “second probability variation big hit” (about 10% Jackpot distribution probability). Thus, in the present embodiment, the probability of occurrence of the “first probability variation big hit” at the time of winning the second start port 38 is higher than the probability of occurrence of “first probability variation big hit” at the time of winning the first start port 36. The probability of occurrence of the “second probability variation big hit” at the time of winning the second starting port 38 is lower than the probability of occurrence of the “second probability variation big hit” at the time of winning the first starting port 36.

  When the big hit symbol is set, the random number for determining the fluctuation pattern is read (step S314), and the fluctuation pattern is selected and set using the read random number for determining the fluctuation pattern and the fluctuation pattern table for big hit (not shown) (step S316). .

  On the other hand, if it is determined in step S306 that the result of the big hit determination is not a big hit, an unillustrated out symbol determination table is set (step S318), and an out symbol is set (step S320). Although the detailed explanation is omitted, for example, the winning symbol can be set using a jackpot symbol determining random number and a not-showing symbol determining table. Of course, if the losing symbol determining random number is acquired separately from the jackpot symbol determining random number, it can be set using the losing symbol determining random number and the losing symbol determining table. When the off symbol is set, the variation pattern determining random number and the reach random number are read out (step S322), and the variation pattern determining random number and the reach random number and the variation pattern table for unillustrated not shown are read out. Select and set (step S324).

  When the jackpot symbol and its variation pattern are set in this way, or when the off symbol and its variation pattern are set, the variation display of the special symbol is started (step S326), and the reserved number of the special symbol is decremented by one. (Step S328), the variation display related process is terminated. This variation display related process is described as a process common to the first special symbol and the second special symbol, but if the current process is a process for the first special symbol, step S326 is performed. In S328, the variable display of the first special symbol is started and the reserved number of the first special symbol is decremented by one. If the current process is a process for the second special symbol, in steps S326 and S328, the variable display of the second special symbol is started to decrement the hold number of the second special symbol by a value of 1. When the special symbol variation display is started in step S326, a symbol variation start command including various symbols, variation patterns, and variation time information is transmitted to the sub-control board 90. The sub control board 90 (effect display control board 91) that has received this symbol variation start command analyzes the command, determines the content of the effect to be performed on the screen of the effect display device 34, and the symbol variation on the effect display device 34. Start production.

  Returning to the special symbol game process of FIGS. 13 to 15, the special symbol game process is executed in a state where the variation display of the special symbol (the first special symbol or the second special symbol) is started and the variation display is executed. Then, since it is determined in step S218 that one of the first special symbol and the second special symbol is in the variable display, the CPU 70a of the main control board 70 determines whether or not the variable display time has elapsed (step S218). S234). Since the variation display time is determined according to the variation pattern when determining the variation pattern of the special symbol, whether or not the variation display time has passed is determined by the special symbol (the first special symbol or the second special symbol). This can be done by comparing the elapsed time from the start of the variable display with the determined variable display time. If it is determined that the variable display time has not elapsed, the special symbol game process is temporarily terminated. If it is determined that the variable display time has elapsed, the variable display of the special symbol (the first special symbol or the second special symbol) is stopped (step S236). When the variable display is stopped, a symbol stop command is transmitted to the sub-control board 90. The sub control board 90 (effect display control board 91) that has received this symbol stop command ends the symbol variation effect on the effect display device 34. Then, a stop display time is set (step S238), and it is determined whether or not the stop display time has elapsed (step S240). Here, the stop display time is an interval from when the special symbol variation display is stopped until the next variation display is started, and is set to 0.6 seconds, for example. If it is determined that the stop display time has not elapsed, the special symbol game process is temporarily terminated. When the special symbol is stopped, when the special symbol game process is executed in the next lap, it is determined in step S220 that the stop display time is in progress, so it is determined again in step S240 whether or not the stop display time has elapsed. If it is determined that the stop display time has elapsed, it is determined whether or not the special symbol that is stopped and displayed is a big hit symbol (step S242).

  If it is determined in step S242 that the game is a big hit symbol, the big hit game flag is turned on (step S244). When the big hit game flag is turned on, a big hit game start command is transmitted to the sub-control board 90. The sub-control board 90 that has received this jackpot game start command executes a jackpot game start effect. Note that the jackpot game start effect is such that a control signal is output to the effect display control board 91 so that the jackpot fanfare screen indicating the occurrence of the jackpot is displayed on the effect display device 34, and sound corresponding to the screen display is output from the speakers 28a and 28b. The driving signal is output to the amplifier board 92 so that the LED signal is output, and the driving signal is output to the decorative driving board 93 so that the LED 93a is turned on corresponding to the screen display. Further, during the big hit game, in order to stop the probability variation function, the time shortening function, and the release extension function, the probability variation flag is turned off when the probability variation flag is on (steps S246 and S248), and the variation shortening flag when the variation shortening flag is on. Is turned off and the release extension flag is turned off (steps S250 to S254), the special symbol game process is terminated, and the process returns to the main control process and proceeds to the next big hit game process of step S150.

  On the other hand, if it is determined in step S242 that the symbol is not a big hit symbol, it is determined whether or not the variation shortening flag is on (step S256). If the variation shortening flag is not on, the special symbol game process is temporarily terminated. When the variation shortening flag is on, the variation shortening counter is decremented by 1 (step S258), and it is determined whether or not the variation shortening counter is 0 (step S260). Here, the fluctuation shortening counter indicates the upper limit value of the number of fluctuations of the special symbol that maintains the state of time reduction (variation shortening of the special symbol and the normal symbol). Is done. When the fluctuation shortening counter is not 0, the special symbol game process is temporarily terminated while maintaining the time shortening state. When the fluctuation shortening counter is 0, the variation shortening flag is turned off in order to terminate the time shortening state ( In step S262), the release extension flag is turned off (step S264), and the special symbol game process is temporarily ended. Thereby, the gaming state of the pachinko machine 10 is changed from the short-time state to the non-short-time state. For example, an effect command indicating the game state is transmitted from the sub control board 90 to the effect display control board 91, Processing such as changing the background screen of the display device 34 from the background for time reduction to the background for non-time reduction is performed. Note that the determination in step S260 is executed regardless of the low probability mode or the high probability mode. However, in the first probability variation big hit and the second probability variation big hit, as described later, after the big hit game ends, Since 10,000 times are set, in the case of these probable big hits, the fluctuation shortening counter cannot normally have a value of 0, and the time reduction state does not end until the next big hit is drawn.

[Big hit game processing]
The jackpot game process of step S150 is executed according to the flowchart shown in FIG. When the jackpot game process of FIG. 20 is executed, the CPU 70a of the main control board 70 first determines whether or not the jackpot game flag is on, that is, whether or not the jackpot game is in progress (step 400). When it is determined that the big hit game flag is off, the big hit game processing is ended as it is. On the other hand, if it is determined that the big hit game flag is ON, it is determined whether or not the big winning opening 44 is open (step S402), and if it is determined that the big winning opening 44 is closed (not open), It is determined whether or not it is the opening timing of the winning opening 44 (step S404). This determination is made, for example, by determining whether or not the first opening timing of the big winning opening 44 has arrived since the start of the big hit game or closing the big winning opening 44 (in this embodiment, 2 seconds). ) Or the like. If it is determined that it is the opening timing of the big prize opening 44, the big prize opening solenoid 44b is driven and controlled so that the big prize opening 44 is opened by the opening / closing plate 55 (step S406), and the big hit game processing is once ended. As described above, when the open / close plate 55 is in the open state, the movable guide plate 57 (inclined surface 57a) provided on the closing surface 55a of the open / close plate 55 does not guide the game ball, and does not play the game ball on the back surface 55b. It will lead to the big prize opening 44. For this reason, even if the movable guide plate 57 is provided on the closing surface 55a of the opening / closing plate 55 that opens and closes the big winning opening 44, the game ball is won by the movable guiding plate 57 at the big winning opening 44 during the big hit game. There is no inhibition. On the other hand, if it is determined in step S404 that it is not the opening timing of the big winning opening 44, the big hit game processing is once ended as it is.

  On the other hand, if it is determined in step S402 that the special winning opening 44 is open, it is determined whether or not it is the closing timing of the special winning opening 44 (step S408). In this determination, either the specified opening time (25 seconds in this embodiment) has elapsed, or the number of game balls that have won the big prize opening 44 has reached the specified number (10 in this embodiment). This is done by determining whether or not If it is determined that it is not the closing timing of the big prize opening 44, the big hit game process is temporarily ended while the big prize opening 44 is kept open. On the other hand, if it is determined that it is the closing timing of the big prize opening 44, the big prize opening solenoid 44b is driven and controlled so that the big prize opening 44 is closed (step S410), and it is determined whether or not the big hit game ending condition is satisfied. Determination is made (step S412). This determination is performed by determining whether or not the special winning opening 44 is opened according to the specified number of rounds. The prescribed number of rounds is set to 2 rounds or 15 rounds according to the type of jackpot (see FIGS. 18 and 19). If it is determined in step S412 that the big hit game end condition is not satisfied, the big hit game processing is once ended. On the other hand, when it is determined that the big hit game end condition is satisfied, the big hit game end process illustrated in FIG. 21 is executed (step S414), and the big hit game process is ended.

  In the big hit game end process of FIG. 21, the CPU 70a of the main control board 70 first turns the big hit game flag from on to off (step S450), and the big hit symbol is the probability variation symbol, that is, the current big hit is “the first probability variation big hit. ”Or“ second probability variation big hit ”is determined (step S452). If it is determined that it is not a probability variation symbol, that is, the current big hit is the “first normal big hit”, the probability variation flag is kept off and the fluctuation shortening counter is set to 100 times (step S454), and the probability variation symbol is determined. Then, the probability variation flag is turned on (step S456), and the variation shortening counter is set to 10,000 times (step S458). As described above, when the fluctuation shortening counter is set to 10,000 times, the time-saving state is substantially continued until the next big hit. When the fluctuation shortening counter is set in this way, the fluctuation shortening flag is turned on (step S460), the release extension flag is turned on (step S462), and the big hit game end process is terminated. When the fluctuation shortening flag and the release extension flag are turned on, a gaming state designation command is transmitted to the sub control board 90. The sub control board 90 that has received this game state designation command, for example, transmits an effect command indicating the game state to the effect display control board 91 to set the background screen of the effect display device 34 as the background for probability change or time reduction. And so on. As described above, when the big probability game of the first probability variation big hit or the second probability variation big hit is completed, the time-saving game is started. Here, during the big hit game, the player hits the right so that the game ball is launched aiming at the big winning opening 44. In addition, as described above, since the game ball is efficiently won at the second starting port 38 by guiding with the movable guide plate 57 (inclined surface 57a) as described above, even during the short time after the big hit game, It can be said that it is preferable to continue to the right. For this reason, the player has only to continue to hit the right from the start of the big hit game until the end of the short-time game.

  According to the pachinko machine 10 of the first embodiment described above, the large winning opening 44 can be opened and closed, and the open / close plate 55 whose front side surface functions as the blocking surface 55a in the closed state closing the large winning opening 44, An inclined surface 57a that can guide the game ball flowing down from the upstream side of the winning opening 44 to the second starting port 38 on the downstream side is formed, and movable guidance provided on the closing surface 55a so as to be movable with respect to the game board 30. Since the opening / closing guiding portion 58 is configured by the plate 57, the number of guiding members to be arranged on the game board 30 is reduced as compared with the case where the movable guiding plate 57 is provided separately from the opening / closing plate 55. The space required for the arrangement of the members can be made small. Further, in a simple configuration in which the movable guide plate 57 is simply provided on the closing surface 55a of the opening / closing plate 55, the opening / closing guiding portion 58 is opened and closed, and the opening / closing of the big prize opening 44 and the guidance of the game ball (large winning prize opening) are performed. 44 or a predetermined object). As a result, it is possible to open and close the special winning opening 44 and guide the game ball to the second start opening 38 with a simple configuration in which the number of components arranged on the game board 30 is suppressed.

  Further, the open / close plate 55 is rotated about the shaft 56 so as to protrude forward with respect to the surface of the game board 30, thereby opening the grand prize winning port 44. In the open state, the back surface 55 b opposite to the closing surface 55 a. Since the range of rotation of the opening / closing plate 55 is determined so as to receive the game ball at, the game ball received on the back surface 55b can be guided to the big prize opening 44 without being obstructed by the movable guide plate 57 provided on the closing surface 55a. it can. Further, since the movable guide plate 57 is formed with an inclined surface 57 a having a length (width) exceeding the size (width) of the opening / closing plate 55, the size of the big prize opening 44 regardless of the size of the big prize opening 44. It is possible to guide the game ball in a wider range. And from the start of the big hit game to the end of the short-time game, the player only needs to continue to make a right stroke, so that the operation mode is easier for the player to understand than the operation mode changes frequently. can do.

  In the pachinko machine 10 according to the first embodiment, the movable guide plate 57 is formed with the inclined surface 57a extending over the entire width of the front plate 54 beyond the size of the opening / closing plate 55. However, the present invention is not limited to this. An inclined surface 57a shorter than the width of the opening / closing plate 55 may be formed, or an inclined surface 57a that fits in the size of the opening / closing plate 55 may be formed. In these cases, an inclined member having an inclined surface that extends the inclined surface 57a of the movable guide plate 57 when the opening / closing plate 55 is closed may be fixed to the left and right of the opening 54a of the front plate 54. The nail may be arranged such that the game ball guided to the inclined surface 57a flows down to the second starting port 38 via the nail on the game board 30. In particular, in the latter case, the movable guide plate 57 and the second start port 38 may be brought close to each other with the required minimum width of the front plate 54 of the special winning opening unit 50.

  Here, the correspondence between the main elements of the first embodiment and the main elements of the invention described in the column of means for solving the problems will be described. In the embodiment, the pachinko machine 10 corresponds to the “game machine”, the game board 30 corresponds to the “game board”, the big prize opening 44 corresponds to the “specific entry opening”, and the opening / closing plate 55 is the “opening / closing member”. ”And“ opening / closing plate ”, and the movable guide plate 57 corresponds to“ movable guide portion ”. Further, the launching device including the firing motor 19 corresponds to the “launching device”, the first starter port 36 corresponds to the “first starter port”, and the second starter port 38 with the ordinary electric accessory 39 is the “first starter”. The main control board 70 that corresponds to “2 start-up” and executes special symbol game processing, jackpot game processing, and the like corresponds to “hit game execution means”, and performs main control that executes normal symbol game processing and normal symbol game processing The board 70 corresponds to “specific game execution means”. The correspondence between the main elements of the embodiment and the main elements of the invention described in the column of means for solving the problem is the same as that of the embodiment described in the column of means for solving the problem. Therefore, the elements of the invention described in the column of means for solving the problems are not limited. In other words, the interpretation of the invention described in the column of means for solving the problems should be made based on the description of the column, and the examples are those of the invention described in the column of means for solving the problems. It is only a specific example.

[Second Embodiment]
Next, a second embodiment will be described. In the second embodiment, since a part of the big prize opening unit 50B has the same configuration except that it is different from the big prize opening unit 50 of the first embodiment, each component other than the big prize opening unit 50B is the first implementation. The same reference numerals as those of the constituent elements of the example are attached and the description thereof is omitted. In the second embodiment, the same processing as that in the first embodiment is performed, and thus the description of the processing is also omitted.

  FIG. 22 shows the appearance of the big prize opening unit 50B with the big prize opening 44 closed, FIG. 23 shows the appearance of the big prize opening unit 50B with the big prize opening 44 open, and FIG. The front view of winning a prize mouth unit 50B is shown. 24A shows a state in which the big prize opening 44 is closed (corresponding to FIG. 22), and FIG. 24B shows a state in which the big prize opening 44 is open (corresponding to FIG. 23). is there. Also in this special prize opening unit 50B, the same components as those in the special prize opening unit 50 of the first embodiment are denoted by the same reference numerals.

  Like the big prize opening unit 50, the big prize opening unit 50B has a unit main body 51 that houses a big prize opening switch 44a, a big prize opening solenoid 44b, and the like, and a front plate on which an opening 54a (large prize opening 44) is formed. 54B, and is fixed to the game board 30 by screwing through the through holes 54b at the four corners of the front plate 54B. In addition, on the closing surface 55a of the opening / closing plate 55 of the front plate 54B, an inclined surface 67a that is inclined downward from the right side to the left side when the game board 30 is viewed from the front is formed. A flat plate-shaped movable guide plate 67 movable with respect to 30 is provided. The movable guide plate 67 is formed in a size that allows the inclined surface 67 a to fit within the lateral width of the opening / closing plate 55. Further, the front plate 54B is a first fixed guide plate disposed on the left and right sides of the opening 54a on the upstream side (right side of the game board 30 when viewed from the front) with respect to the movable guide plate 67 when the open / close plate 55 is closed. 61 and a second fixed guide plate 63 disposed on the downstream side of the closed movable guide plate 67 (left side when the game board 30 is viewed from the front) are fixed. The inclined surface 61a on the upper surface of the first fixed guide plate 61 and the inclined surface 63a on the upper surface of the second fixed guide plate 63 are inclined surfaces 67a of the movable guide plate 67 when the open / close plate 55 is closed. Are formed to be flush with each other at substantially the same inclination angle (downward gradient). That is, the first fixed guide plate 61 extends the inclined surface 67a of the movable guide plate 67 upstream, and the second fixed guide plate 63 extends the inclined surface 67a of the movable guide plate 67 downstream. To be. For this reason, the inclined surface 67a of the movable guide plate 67, the inclined surface 61a of the first fixed guide plate 61, and the inclined surface 63a of the second fixed guide plate 63 are in the closed state. A guiding function for guiding the game ball from the right side to the left side is exhibited (see FIG. 22). Also in the second embodiment, the opening / closing plate 55 has a function of opening / closing the grand prize opening 44, and the movable guide plate 67 has a function of guiding the game ball to the second starting port 38. The combination with the movable guide plate 67 is referred to as an opening / closing guide 68.

  On the other hand, when the opening / closing plate 55 rotates about the shaft 56 and the opening / closing plate 55 is in the open state, the opening / closing plate 55 protrudes forward from the board surface of the game board 30. (Front side) faces down, and back side 55b (rear side) faces up. For this reason, the movable guide plate 67 provided on the closing surface 55a (front surface) does not exhibit the guidance function of the game ball. And the game ball guidance part formed in the back surface 55b of the opening-and-closing board 55 will exhibit a guidance function. In this open state, the back surface 55b (game ball guiding portion) of the opening / closing plate 55 is lower than the inclined surface 61a of the first fixed guide plate 61 and the inclined surface 63a of the second fixed guide plate 63, that is, Steps between the open / close plate 55 and the first fixed guide plate 61 and between the open / close plate 55 and the second fixed guide plate 63 (the left and right end portions of the back surface of the open / close plate are fixed guide plates 61). , 63 is set so that the rotation range of the opening / closing plate 55 of the opening / closing guiding portion 68 is determined. Further, at these steps, the distance S1 (see the enlarged view in FIG. 23) between the opening / closing plate 55 (back surface 55b) and the first fixed guide plate 61 (bottom surface), the opening / closing plate 55 (back surface 55b) and the second. The distance S2 (see the enlarged view in FIG. 23) with the fixed guide plate 63 (the lower surface thereof) is smaller than the diameter of the game ball. In the present embodiment, the intervals S1 and S2 are obtained when the special winning opening 44 is open, and the inclined surfaces are flush with each other at substantially the same inclination angle (downward gradient) when the special winning opening 44 is closed. Further, the movable guide plate 67, the first fixed guide plate 61, and the second fixed guide plate 63 are arranged. As described above, the first fixed guide plate 61 and the second fixed guide plate 63 are configured so that the inclined surfaces 61a and 63a extend the inclined surface 67a of the movable guide plate 67 when the opening / closing plate 55 is in the closed state. It functions to guide the game ball, and when the open / close plate 55 is in an open state, the game ball received on the back surface 55b of the open / close plate 55 is prevented from flowing down to the left or right without winning the big prize opening 44. Thus, it functions as a guard member that suppresses the flow of the game ball.

  Since the big prize opening unit 50B is configured in this way, the flow of the game ball that is fired by right-handed to the player and flows down from the right area of the gaming area 31 to the upstream side of the big prize opening 44 is as follows. become. First, if the open / close plate 55 is in a closed state (the big prize opening 44 is in a closed state), the movable guide plate 67 protrudes forward with respect to the board surface of the game board 30, so the upstream side of the big prize opening 44. When the game ball that flows down reaches the first fixed guide plate 61 and the movable guide plate 57, it is guided from the right side to the left side along the respective inclined surfaces (the inclined surface 61a, the inclined surface 57a, and the inclined surface 63a). (Arrow in FIG. 22). That is, the movable guide plate 67 exhibits a game ball guiding function together with the first fixed guide plate 61 and the second fixed guide plate 63. For this reason, also in the second embodiment, the game balls guided by the movable guide plate 57, the first fixed guide plate 61, and the second fixed guide plate 63 flowing down the upstream side of the big winning opening 44 are: It will be guided to the second starting port 38 on the downstream side of the big prize winning port 44. If the opening / closing plate 55 is in the open state (the big winning opening 44 is in the open state), the opening / closing plate 55 protrudes forward with respect to the board surface of the game board 30, and the movable guide plate 57 functions to guide the game ball. Therefore, when the game ball flowing down the upstream side of the big winning opening 44 reaches the opening / closing plate 55, it will win the big winning opening 44 along the back surface 55b (game ball guiding portion) (FIG. 23). Middle arrow). At this time, since the first fixed guide plate 61 and the second fixed guide plate 63 function as a guard member that suppresses the flow of the game ball from the back surface 55b, the winning of the game ball to the big winning opening 44 is achieved. You will be prompted.

  According to the pachinko machine 10 of the second embodiment described above, the large winning opening 44 can be opened and closed, and the opening / closing plate 55 whose front side surface functions as the blocking surface 55a in the closed state closing the large winning opening 44, An inclined surface 57a that can guide the game ball flowing down from the upstream side of the winning opening 44 to the second starting port 38 on the downstream side is formed, and movable guidance provided on the closing surface 55a so as to be movable with respect to the game board 30. An opening / closing guiding portion 68 composed of a plate 67 and inclined surfaces 61a and 63a that can extend the inclined surface 67a of the movable guiding plate 67 in the closed state are formed and fixed to the game board 30 so as to be immovable. Since the first and second fixed guide plates 61 and 63 are provided, the number of guide members to be arranged on the game board 30 is reduced as compared with the case where the movable guide plate 57 is provided separately from the opening / closing plate 55. Necessary for placement of guide members Space can be the the small things that. In addition, with a simple configuration in which the movable guide plate 57 is simply provided on the closing surface 55a of the opening / closing plate 55, it is possible to open and close the special winning opening 44 and guide the game ball. Further, since the inclined surface 67a of the movable guide plate 67 in the closed state is extended by the fixed guide plates 61 and 63, the length of the inclined surface 67a of the movable guide plate 67 is restricted by the size of the big prize opening 44 and the opening / closing plate 55. Even in the case of a game, it is possible to appropriately guide the game ball by forming a necessary inclined surface. As a result, it is possible to open and close the special winning opening 44 and guide the game ball to the second start opening 38 with a simple configuration in which the number of components arranged on the game board 30 is suppressed.

  Further, the open / close plate 55 is rotated about the shaft 56 so as to protrude forward with respect to the surface of the game board 30, thereby opening the grand prize winning port 44. In the open state, the back surface 55 b opposite to the closing surface 55 a. Since the range of rotation of the opening / closing plate 55 is determined so as to receive the game ball at, the game ball received on the back surface 55b can be guided to the big prize opening 44 without being obstructed by the movable guide plate 57 provided on the closing surface 55a. it can. Further, since the first and second fixed guide plates 61 and 63 function as a guard member that suppresses the flow of the game ball when the special winning opening 44 is opened, guidance of the game ball to the second start port 38, It can also be used for efficient winning of game balls to the big winning opening 44. Since the first and second fixed guide plates 61 and 63 are formed such that the inclined surfaces 61a and 63a are flush with the inclined surface 67a of the inclined plate 67 in the closed state, and are flush with each other. Can be guided more smoothly. In addition, since the first and second fixed guide plates 61 and 63 are provided on the upstream side and the downstream side of the opening / closing guide part 68, respectively, the size of the big prize opening 44 is larger than the size of the big prize opening 44. A game ball can be guided in a wide range. And from the start of the big hit game to the end of the short-time game, the player only needs to continue to make a right stroke, so that the operation mode is easier for the player to understand than the operation mode changes frequently. can do.
