To do.

  Next, in step S102, processing relating to medal insertion is performed. Here, it is checked whether or not medals have been inserted, and the winning line display lamp 120 is turned on according to the number of medals inserted. It is not necessary to insert a medal when winning the re-game in the previous game.

  In step S103, processing related to a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated. If it is determined that the start operation has been performed, the number of inserted medals is confirmed to determine a valid winning line 114 (step S104).

  In step S105, the random number generated by the random number generation circuit 317 is acquired.

  In step S106, the winning combination lottery is performed using the random number value acquired in S104 and the winning combination lottery table stored in the ROM 312.

  The type of winning combination may be arbitrarily adopted, but in this embodiment, there are a regular bonus (RB), a big bonus (BB), a small combination, a replay, and the like. For each winning combination, lottery data is set for each set value and each inserted number. The number obtained by dividing the lottery data by a predetermined value (specifically, 16384, which is the entire range of random numbers used in the winning combination lottery) is the winning probability. In other words, the range of random values acquired at the time of winning combination lottery is divided in advance into several areas (areas corresponding to the size of each lottery data), and each area is associated with winning or losing of each winning combination. It has been. These pieces of information are stored in the ROM 312 as a winning combination lottery table. In the winning combination lottery, the winning combination of the winning combination is determined according to which range the acquired random number value belongs.

  In step S111, a winning determination is performed. Here, when a combination of symbols corresponding to the winning combination is displayed on the activated winning line 114, it is determined that the winning combination is a winning combination. For example, if “bell-bell-bell” is arranged on the validated winning line 114, it is determined that the bell is won. In addition, if “7-7-7” is prepared, it is determined that a BB winning is achieved. The winning result is stored as a winning result code.

  In step S112, if any winning combination with a payout has been won, the number of medals corresponding to the winning combination is paid out.

  In step S113, a game state control process is executed. In this game state control process, control for shifting the type of game is performed. For example, in the case of winning a BB game, preparation is made so that the BB game can be started from the next time. Prepare to start the game.

  As described above, one game is completed, and thereafter, the game progresses by repeating this (the processing of step S102 to step S113).

  In addition to the effect commands described above, various commands exist in the commands transmitted from the main control unit 300 to the sub control unit 400. In the following description, steps in parentheses indicate transmission timing.

  That is, the start lever operation command (command indicating start lever acceptance: S103), the first stop operation command (information indicating the reel on which the first stop operation has been performed are stored, and the first stop operation is performed. Command transmitted: S110), first reel stop command (information indicating the stopped first reel is stored and transmitted when the first reel is stopped: S110), similar second stop operation command, first reel There are a two-reel stop command, a third stop operation command, a third reel stop command, and a winning determination information command (a command storing a winning result: S111). Although not particularly illustrated, the effect command is transmitted when a predetermined condition is satisfied (for example, when a bonus is awarded (when RB or BB is awarded) other than S108.

  As described above, the slot machine 100A is provided corresponding to each of a plurality of reels (for example, three reels 110 to 112) on which a plurality of types of patterns are applied, and rotates the reels. A stop switch (for example, three stop buttons 137 to 139) for stopping individually and whether or not the internal winning of a predetermined winning combination is determined by lottery. When the combination of the pictures displayed by the reel at the time is a combination of pictures predetermined corresponding to the internal winning winning combination, it is determined that the winning combination is won and a predetermined game is performed.

On the other hand, the sound introduction hole 611a of the upper box 611 is designed to have a size facing the position corresponding to the back side sound hole 160b provided in the back plate 101a of the slot machine 100A installed in the game machine installation table 700 (see FIG. 6). .

  In other words, in the speaker box 610 according to the present embodiment, the sound introduction hole 611a of the upper box 610 functions as a “sound introduction part that takes in sound output from the speaker of the game stand”, and the upper box 611 and the lower guide tube 613. And the horn 614 work together to function as an “acoustic guiding section for guiding the sound taken in from the acoustic introducing section”, and the sound derivation hole 614 of the horn 614 reads “the sound guided from the acoustic guiding section at an appropriate place on the amusement island. It functions as a “sound output unit that outputs more”.

  Furthermore, in the speaker box 610 according to the present embodiment, the horn 614 is placed in the lower space (the space below the game table in the internal space of the game island) of the game table installation table 700 having a relatively large space. Since it is arranged, the opening diameter of the sound derivation hole 614b of the horn 614 can be configured to be large so as to be a large-diameter sound output section, enabling a heavy bass output and enhancing the sound effect. it can.

The sound hole 623a of the lower box 623 (the opening on the front side of the bass reflex duct 624) is designed to face the sound hole 701a opened at a proper position on the lower front panel 701, and is mounted in the sound introduction hole 621a of the upper guide pipe 621. The round hole 622a of the packing 622 is designed in such a size as to face the position corresponding to the back side sound hole 160b provided in the back plate 101a of the slot machine 100A installed in the game machine installation table 700.

  As shown in FIG. 7 (b), if a flexible tube is used as the upper guide pipe 621 ', the opening position of the back side sound hole 160b of the game stand installed on the game island and the sound introduction hole of the upper guide pipe 621' are provided. Even if the position is shifted from 621a ′, the error can be absorbed without difficulty and the game table can be installed effectively. In addition, when the flexible tube-shaped upper guide pipe 621 ′ is used, the sound introduction hole 621a ′ may be displaced from the back side sound hole 160b of the game table by being deformed by receiving a physical impact. You may make it fix to a game stand with the fixing tool 625. FIG.

  The speaker boxes 610 and 620 according to the first and second embodiments described above are configured so as to correspond to the slot machine 100A in which the low-frequency speaker 170 is provided on the back surface side. It is possible to arbitrarily change the position and shape of the speaker box according to the table.

  A slot machine 100B as a gaming table shown in FIG. 8 has a structure in which a bass speaker 170 is provided on the bottom plate 101b of the main body 101, and a sound introduction port faces the bass speaker 170 from below the gaming table installation table 700 on the gaming island. By providing the speaker box 630 according to the third embodiment designed so that the sound derivation hole faces the sound hole 701a opened at a proper position of the lower front panel 701, the acoustic effect is enhanced. The sound enhancement structure of the speaker box 640 may be a back load horn type, a bass reflex type, or other structures. Also, in FIG. 8, a phantom line (dashed line) shows a reel unit and a coin hopper, which are relatively large components inside the slot machine 100B, and a low-frequency speaker 170 is provided at an appropriate position that does not hinder these. be able to.

  A slot machine 100C as a gaming table shown in FIG. 9 has a structure in which a low-frequency speaker 170 is provided on a side plate 101c of a main body 101, and a sound introduction port faces the low-frequency speaker 170 through the side plate 101c. The acoustic effect is enhanced by providing the speaker box 640 according to the fourth embodiment designed so that the sound guide hole faces the inter-base separation panel disposed therebetween. The sound enhancement structure of the speaker box 640 may be a back load horn type, a bass reflex type, or other structures. Also, in FIG. 9, a phantom line (dashed line) indicates a reel unit and a coin hopper, which are relatively large components inside the slot machine 100C, and a low-frequency speaker 170 is provided at an appropriate place that does not hinder these. be able to.

  A slot machine 100D as a game table shown in FIG. 10 has a structure in which a low-frequency speaker 170 is provided on a top plate 101d of a main body 101, and a sound introduction port faces the low-frequency speaker 170 through the top plate 101d. The acoustic effect is enhanced by providing the speaker box 650 according to the fifth embodiment designed so that the sound lead-out hole faces the upper front panel arranged above the game table. The sound enhancement structure of the speaker box 650 may be a back load horn type structure, a bass reflex type structure, or another structure.

  Each of the speaker boxes of the above-described embodiments is configured to introduce sound from the bass speaker 170 provided on the wall surface of the main body of the game machine. However, the speaker arrangement configuration in the game machine is not limited to the above example. It is only necessary to form a sound hole through which the sound output from the bass speaker 170 is derived. For example, as in the slot machine 100E shown in FIG. 11, the low-frequency speaker 170 is arranged in the acoustic duct 171 that connects the front sound hole 160a and the back sound hole 160b, and is provided in the sound introduction hole of the speaker box 660. The packing 661 may be arranged so as to correspond to the back side sound hole 160b. In this case, one of the sounds emitted from both sides of the speaker 170 (the same sound having the opposite phase produced by the back and forth movement of the diaphragm) is emitted from the front sound hole 160a of the game table, and the other is sounded by the speaker box 660. Since it can be put out from a suitable place on the game island as an enhanced good bass, a sound effect suitable for enhancing amusement interests can be expected.

  In addition, each of the speaker boxes of the above-described embodiments adopts an acoustic enhancement structure to enhance the acoustic effect. However, the present invention is not limited to this, for example, the sound taken in from the acoustic introduction unit is transmitted by the acoustic induction unit. It is good also as a simple structure which guides and outputs to an acoustic output part.

Next, a reference example of the acoustic system of the game island that enhances the acoustic effect of the game stand on the game island will be described. In addition, the acoustic system of the game island is greatly different from the above-described speaker box in that a sound is produced by operating a speaker included in the game system based on sound information supplied from the game stand. However, there is a technical feature in that an electrical connection work or the like is not required by using a contactless communication form between the game table and the game island.

FIG. 12A shows a schematic configuration of the acoustic system of the game island according to the first reference example. The slot machine 100F as a game table is a speaker 173 operated by an electric signal supplied through a signal line 172. When the slot machine 100F is installed in the game table installation table 700, the sound information reception hole 700a opened in the game table installation table 700 is set to face the sound information transmission hole 174 opened in the bottom plate 101b. The sound information transmission hole 174 faces.

  A microphone 671 is arranged in the sound information receiving hole, and the air close-packed wave (output sound itself) generated by the operation of the speaker 173 is received by the microphone 671 and converted into an electric signal, which is converted into this electric signal. The received signal is sent to the amplifier 673 via the signal line 672, and the amplifier 673 receiving the signal sends the drive signal generated by appropriately amplifying the received signal to the game island speaker 675 via the signal line 674, and the lower front panel. Sound is output from the 700 sound holes 701a. The amplifier 673 is supplied with operating power via a power cable 676.

That is, in the game island acoustic system according to the present reference example , the game machine uses sound waves as a non-contact communication form with the game island side, and the speaker 173 of the slot machine 100F is connected to the sound information generated in the game machine. Functioning as “sound information transmitting means for transmitting to the side”, causing the microphone 671 to function as “sound information receiving means for receiving sound information transmitted from the game console”, and the amplifier 673 for “signal received by the sound information receiving means” The amusement island speaker 675 is allowed to function as a “speaker that operates with a signal output from the amplifying means”.

Note that the non-contact communication form between the game table and the game island is not limited to using a sound wave, and a known non-contact signal transmission form such as a radio wave or light may be appropriately used. For example, in the acoustic system of the game island according to the second reference example shown in FIG. 12 <b>, sound information is transmitted using optical communication.

  The slot machine 100G, which is a game machine, has a light emitting element 176 that is turned on / off by a pulse wave output from a photoelectric converter 175 that quantizes an electric signal (analog waveform) supplied via a signal line 172, and a bottom plate 101b. When the slot machine 100G is installed in the game table installation table 700 with the configuration facing the sound information transmission hole 174 opened in, the sound information transmission hole is inserted into the sound information reception hole 700a opened in the game table installation table 700. 174 is facing.

  A light receiving element 681 is disposed in the sound information receiving hole, and a photoelectric converter 682 that converts a pulse wave generated in the light receiving element 681 in response to blinking of the light emitting element 176 into an electric signal (analog waveform) is a signal line. The received signal is sent to the amplifier 673 via 683, and the amplifier 684 receiving this sends the drive signal generated by amplifying the received signal as appropriate to the game island speaker 686 via the signal line 685. Sound is output from the hole 701a. The amplifier 684 is supplied with operating power via a power cable 684.

That is, in the acoustic system of the gaming island according to this reference example , the gaming machine uses an optical signal as a non-contact communication form with the gaming island side, and the photoelectric converter 157 and the light emitting element 176 of the slot machine 100G are connected to “inside the gaming machine”. Function as sound information transmitting means for transmitting the generated sound information to the game island side, and make the light receiving element 681 and the photoelectric converter 682 function as “sound information receiving means for receiving sound information transmitted from the game table”; The amplifier 684 is made to function as “amplifying means for amplifying the signal received by the sound information receiving means”, and the game island speaker 686 is made to function as “speaker operating with the signal output from the amplifying means”.

In the game island acoustic systems according to the first and second reference examples described above, the sound information output from the game control unit (for example, the sub-control unit A300) of the game table is either analog data or digital data. Therefore, it is not necessary to greatly change the configuration of the game control unit of the game table, and it can be easily applied to an existing game table.
