Attached to.

  Here, the control system of the slot machine 1 shown in FIG. 1 will be described with reference to FIG. As described above, the slot machine 1 is provided with the main control circuit 25. The main control circuit 25 uses the microcomputer 34 disposed on the circuit board as a main component, and the microcomputer 34 performs random number sampling. The circuit is added. The microcomputer 34 includes a CPU 35, a ROM 36, and a RAM 37 that perform control operations according to a preset program.

  In the illustrated example, the CPU 35 is connected to a clock pulse generation circuit 38 and a frequency divider 39 for generating a reference clock pulse, and a random number generator 40 and a sampling circuit 41 for generating a random number to be sampled. As a means for random number sampling, random number sampling may be executed in the microcomputer 34, that is, on the operation program of the CPU 35. In this case, the random number generator 40 and the sampling circuit 41 can be omitted, but may be left as a backup for the random number sampling operation.

  The ROM 36 determines the stop mode of the reel in accordance with the operation of the probability lottery table, the stop winning combination determination table, and the stop button used for determination of random number sampling performed every time the start lever 18 is operated (start operation). For example, information such as a stop table group is stored, and the ROM 36 stores various control commands (commands) transmitted to the sub-control circuit 24.

  In the illustrated example, the sub control circuit 24 does not input commands, information, or the like to the main control circuit 25, and communication is performed in one direction from the main control circuit 25 to the sub control circuit 24. Various information is stored in the RAM 37. For example, information such as an internal winning combination, a carryover combination and the current gaming state is stored.

  In FIG. 3, as a main actuator controlled by a control signal transmitted from the microcomputer 34, for example, a BET lamp (1-BET lamp 10a, 2-BET lamp 10b, maximum BET lamp 10c) and bonus game information display are displayed. Information display unit 13 such as a copy unit, a payout display unit, a credit display unit, a hopper 43 (including a drive unit for payout) 43 that stores medals and pays out a predetermined number of medals according to a command from the hopper drive circuit 42, a reel There are stepping motors 44L, 44C, and 44R that rotate and drive 11L, 11C, and 11R.

  Further, in the illustrated example, a motor drive circuit 45 that drives and controls the stepping motors 44L, 44C, and 44R, a hopper drive circuit 42 that drives and controls the hopper 43, and a lamp drive circuit that controls and drives the BET lamps 10a, 10b, and 10c. 46 and a display unit driving circuit 47 for driving and controlling the information display unit 13 are connected to the output unit of the CPU 35. These drive circuits each receive a control signal such as a drive command output from the CPU 35 and control the operation of each actuator described above.

  As main input signal generating means for generating an input signal necessary for the microcomputer 34 to generate a control command, for example, a start switch 18S, stop switches 19LS, 19CS, and 19RS, 1-BET switch 6, 2-BET There are a switch 7, a maximum BET switch 8, a C / P switch 15, a medal sensor 9S, a reel position detection circuit 48, and a payout completion signal circuit 49.

  The start switch 18S detects the operation of the start lever 18 and outputs a game start command signal (signal for instructing the start of the game). The medal sensor 9S detects medals inserted into the medal insertion slot 9. The stop switches 19LS, 19CS, and 19RS generate stop command signals (signals for instructing to stop changing the symbols) in response to operations of the stop buttons 19L, 19C, and 19R, respectively. The reel position detection circuit 48 receives the pulse signal from the reel rotation sensor and supplies a signal for detecting the position of each reel 11L, 11C, and 11R to the CPU 35. When the count value (the number of medals paid out from the hopper 43) of the medal detection unit 43S reaches the designated number data, the payout completion signal circuit 49 generates a signal for detecting completion of the medal payout.

  The random number generator 40 generates random numbers belonging to a certain numerical range, and the sampling circuit 41 samples one random number at an appropriate timing after the start lever 18 is operated. By using the random number sampled in this way, for example, an internal winning combination is determined according to a probability lottery table or the like stored in the ROM 36. The internal symbol combination (internal symbol combination data) is indirectly associated with the corresponding symbol combination and the profit given to the player through the stop control mode or display combination corresponding to the internal symbol combination. ing.

  When the reels 11L, 11C, and 11R start rotating, the number of drive pulses supplied to each of the stepping motors 44L, 44C, and 44R is counted, and the counted value is written in a predetermined area of the RAM 37. From the reels 11L, 11C, and 11R, reset pulses are obtained every rotation, and these pulses are input to the CPU 35 via the reel position detection circuit 48. The count value of the drive pulse counted in the RAM 37 is cleared to “0” by the reset pulse thus obtained. As a result, the count value corresponding to the rotational position within one rotation range is stored in the RAM 37 for each of the reels 11L, 11C, and 11R.

  In order to associate the rotational positions of the reels 11L, 11C, and 11R with the symbols drawn on the outer peripheral surface of the reel, a symbol table (not shown) is stored in the ROM 36. This symbol table Then, with reference to the rotational position where the reset pulse is generated as a reference, the code number sequentially given for each fixed rotation pitch of each reel 11L, 11C, and 11R, and the symbols provided corresponding to each code number Is associated with a symbol code.

  Furthermore, a symbol combination table (not shown) is stored in the ROM 36. In this symbol combination table, a symbol combination that establishes a winning combination (winning, etc.), a medal payout number of winning, and a winning determination code (establishing determining code) indicating the winning (establishment) are associated with each other. The above symbol combination table is used when confirming winning (checking the display combination) at the time of stop control of the left reel 11L, the center reel 11C, and the right reel 11R and after stopping all the reels 11L, 11C, 11R. Referenced. The display combination (display combination data) is basically a combination (established combination) corresponding to the symbol combination arranged along the effective line. The player is given a profit corresponding to the display combination.

  When an internal winning combination or a stop winning combination is determined by lottery processing (probability lottery processing or the like) based on the above random number sampling, the CPU 35 is the timing at which the player operates the stop buttons 19L, 19C, and 19R. Based on the operation signal sent from the stop switches 19LS, 19CS, and 19RS and the determined stop table, a signal for controlling the reels 11L, 11C, and 11R to stop is sent to the motor drive circuit 45.

  If it becomes a stop mode (that is, a winning mode) indicating a winning combination, the CPU 35 supplies a payout command signal to the hopper driving circuit 42 and pays out a predetermined number of medals from the hopper 43. At that time, the medal detection unit 43S counts the number of medals to be paid out from the hopper 43, and when the count value reaches a designated number, a medal payout completion signal is input to the CPU 35. As a result, the CPU 35 stops driving the hopper 43 via the hopper drive circuit 42 and ends the medal payout process.

  Here, the control operation of the main control circuit 25 will be described in detail with reference to FIGS. First, the CPU 35 performs initialization at the start of the game (step S1). For example, the contents stored in the RAM 37 are initialized and the communication data is initialized. Subsequently, the CPU 35 erases predetermined storage contents (information on a predetermined storage area (for example, an area for storing an internal winning combination)) in the RAM 37 at the end of the game (step S2), and proceeds to step S3. In step S2, for example, the data in the writable area of the RAM 37 used in the previous game is erased, the parameters necessary for the next game are written in the write area of the RAM 37, and the start address of the sequence program of the next game is set. Designation is performed.

  In step S3, the CPU 35 performs medal insertion / start check processing. In this medal insertion / start check processing, processing such as updating the number of BETs is performed based on inputs from the start switch 18S, the sensors in the medal selector 31, or the BET switches 6-8. After performing step S3, the CPU 35 proceeds to step S4, where a random number for lottery is extracted in step S4 (the random number extracted in this process is used in a probability lottery process described later). Then, the CPU 35 proceeds to step S5.

  In step S5, the CPU 35 performs a gaming state monitoring process. In this gaming state monitoring process, for example, the gaming state is monitored based on the FT operating flag, the presence / absence of a carryover combination, the BB operating flag, and the RB operating flag, and the probability lottery table corresponding to the gaming state is switched. Then, the CPU 35 proceeds to step S6. In step S6, the CPU 35 performs a probability lottery process for determining an internal winning combination based on the switched probability lottery table, and proceeds to step S7.

  In step S7, the CPU 35 performs stop table selection processing for selecting a stop table based on an internal winning combination or the like, and then sets a start command (step S8). The start command includes information such as a gaming state and an internal winning combination, and is transmitted to the sub-control circuit 24. Then, the CPU 35 determines whether or not “predetermined time (for example, 4.1 seconds)” has elapsed since the previous game started (step S9). If this determination is YES (that is, if 4.1 seconds have elapsed), the CPU 35 proceeds to step S11, and if NO (that is, if 4.1 seconds have not elapsed), the CPU 35 proceeds to step S10. .

  In step S10, the CPU 35 performs a game start waiting time digest process (wait process), and then proceeds to step S11. For example, in this wait process, an operation for starting a player's game until a predetermined time (for example, a predetermined second (such as “4.1 seconds”)) has elapsed since the previous game started. Process to invalidate input based on. In step S11, the CPU 35 sets a game monitoring timer (in this game monitoring timer, the reels 11L, 11C, and 11R are automatically loaded regardless of the stop operation of the player's stop buttons 19L, 19C, and 19R. Automatic stop timer to stop).

  Subsequently, the CPU 35 requests the start of rotation of all reels (step S12), sets a reel stop permission command (step S13), and then proceeds to step S14 shown in FIG. In step S14, the CPU 35 determines whether or not the stop switch is “ON”, that is, whether one of the stop buttons 19L, 19C, and 19R has been operated. When the determination is YES (that is, when any stop button is operated), the CPU 35 proceeds to step S16, and when the determination is NO (that is, any stop button is not operated), the process proceeds to step S15. Move. In step S15, the CPU 35 determines whether or not the value of the automatic stop timer is “0”. When this determination is YES (that is, “0”), the CPU 35 proceeds to step S16, and when NO (that is, not “0”), the CPU 35 returns to step S14.

  In step S16, the CPU 35 performs a sliding frame number determination process. Subsequently, in step S17, the reels 11L, 19C, and 19R corresponding to the stop buttons 19L, 19C, and 19R that have been operated to stop by the number of sliding frames determined in step S16. After waiting for the rotation of 11C and 11R, the process proceeds to step S18.

  In step S18, the CPU 35 requests a reel rotation stop, and subsequently sets a reel stop command (step S19). And CPU35 discriminate | determines whether all the reels stopped (step S20). When this determination is YES (that is, when all reels are stopped), the CPU 35 proceeds to step S21 shown in FIG. 6, and when it is NO (when all reels are not stopped), the process returns to step S14. .

  In step S21, the CPU 35 performs a display combination search process. In this display combination search process, a flag for identifying a display combination (a winning combination) is set based on a symbol stop mode in the symbol display area. Subsequently, the CPU 35 determines whether or not there is an illegal hit, that is, whether or not there is a mismatch between the internal winning combination and the display combination (step S22). When this determination is YES (when there is a mismatch), the CPU 35 displays an illegal error (step S23) and stops the game. On the other hand, if NO (no inconsistency), the CPU 35 performs FT termination processing (step S24), and proceeds to step S25.

  In step S25, after setting the display combination command including the display combination information, the CPU 35 determines whether or not the number of payouts corresponding to the display combination is “0” (step S26). When this determination is YES (when it is “0”), the CPU 35 proceeds to step S28, and when it is NO (when it is not “0”), the CPU 35 proceeds to step S27. In step S27, the CPU 35 stores (credits) or pays out medals, and proceeds to step S28. In step S28, after setting the payout end command, the CPU 35 proceeds to step S29.

  In step S29, the CPU 35 determines whether or not the RB operating flag or the BB operating flag is “ON”. When this determination is YES (when it is on), the CPU 35 proceeds to step S31, and when it is “NO” (when it is not on), the CPU 35 proceeds to step S30.

  The RB operating flag is information for identifying whether or not the RB gaming state is set, and is “ON” when in the RB gaming state, and “OFF” when not in the RB gaming state. The BB operating flag is information for identifying whether or not the player is in the BB gaming state, and is “ON” when in the BB gaming state, and “OFF” when not in the BB gaming state. Therefore, in the RB gaming state during BB, both flags are “ON”. In the general RB gaming state, the RB operating flag is “ON” and the BB operating flag is “OFF”.

  In step S30, the CPU 35 performs RB and BB operation check processing, and then returns to step S2 shown in FIG. In the RB and BB operation check processing, when the display combination is RB, the RB operation flag is turned on, when the display combination is BB, the BB operation flag is updated to ON, and the FT operation flag is on. In this case, a process of updating to off is performed. In step S31, RB and BB end check processing is performed, and the process returns to step S2 shown in FIG.

  Next, the structure below the front door 2b will be described with reference to FIG. FIG. 7 is a view showing the lower part of the front door 2b from the back side (back side). In the illustrated example, the front door body 21 includes a resin frame 50, and the frame 50 has the above-described medal holder.

A screw hole 511 into which the screw 54 is screwed is formed. Note that the frame 50 does not extend to the lower end of the front door 2b, and the through hole 532 is exposed on the back side of the front door 2b.

  Accordingly, a conductive (metal) screw (second connecting means) 54 is inserted into the through hole 532 of the coin guard plate 53 and the through hole 521 of the tray guard plate 52, and this screw 54 is inserted into the medal receiving portion main body 51. The coin guard plate 53 and the tray guard plate 52 are fixed to the medal receiving portion main body 51 while being in contact with each other.

  In the coin guard plate 53, a through hole 533 is formed in a region overlapping with the hinge part 33. Although not shown, the frame 50 and the hinge part 33 are formed with through holes corresponding to the through hole 533, respectively. As will be described later, a conductive (metal) screw (for example, M4 screw: first connecting means) is inserted into these through holes to electrically connect the coin guard plate 53 and the hinge portion 33. .

  FIG. 11 is a view showing a state in which the coin guard plate 53 is attached to the frame 50 from the back side (back side), and a through hole 331 (not shown in FIG. 11) is formed in the hinge portion 33. 331 overlaps with a through hole 533 (not shown in FIG. 11) shown in FIG. Referring to FIG. 12, for example, a conductive M4 screw 55 is inserted through the through hole 331 and the through hole 533, and the coin guard plate 53 is electrically connected to the hinge portion 33 by the M4 screw 55. The M4 screw 55 is screwed into the frame 50 and reaches the back side of the frame 50, and the hinge portion 33 and the coin guard plate 53 are electrically connected by the M4 screw 55.

  As described above, the coin guard plate 53 and the tray guard plate 52 are fixed to the medal receiving portion main body 51 in contact with each other, and the coin guard plate 53 is connected to the hinge portion 33 by the conductive M4 screw 55. Therefore, the coin guard plate 53 is electrically connected to the cabinet 2a (that is, the main body casing) via the hinge portion 33 as a result. As a result, the medal receiving portion (coin tray) can be effectively neutralized.
