  The ROM stores control codes, fixed data, and the like indicating a user program (game control processing program for game control). The RAM provides a work area for game control and the like. Here, at least a part of the RAM may be a backup RAM backed up by a backup power supply. That is, even if the power supply to the slot machine 1 is stopped, at least a part of the contents of the RAM is stored for a predetermined period.

  The main control unit 41 transmits various commands to the sub control unit 91 via the parallel output port. The command transmitted from the main control unit 41 to the sub control unit 91 is transmitted in only one direction, and the command is not transmitted from the sub control unit 91 to the main control unit 41. In this embodiment, the command is transmitted to the sub-control unit 91 through the parallel output port, that is, the command is transmitted as a parallel signal. A configuration for transmitting a command to the unit 91, that is, a configuration for transmitting the command as a serial signal may be employed.

  The main control unit 41 repeatedly loops processing according to the control state until the detection state of various switches connected to the game control board 40 changes as basic processing, and responds to the change in the detection state of various switches. Execute the process of shifting in stages. In addition, the main control unit 41 executes the timer interrupt processing (main) at regular time intervals (about 0.56 ms in the present embodiment). Note that the execution interval of the timer interrupt processing (main) is set to a time longer than the sum of the time taken for the repetition of the processing according to the control state in the basic processing and the execution time of the timer interrupt processing (main). Thus, at least one cycle of the process repeated according to the control state between the current and next timer interrupt processes (main) is performed at least.

  The above-described effect switch 56 and the like are connected to the effect control board 90, and detection signals of these connected switches are input. Further, to the effect control board 90, effect devices such as a liquid crystal display 51, an effect LED 52, speakers 53 and 54, a reel LED 55, and the like are connected, and these effect devices are mounted on the effect control substrate 90 and described later. It is driven based on the control by the sub-control unit 91.

  In this embodiment, the sub-control unit 91 mounted on the effect control board 90 controls the output of the effect devices such as the liquid crystal display 51, the effect LED 52, the speakers 53 and 54, and the reel LED 55. However, an output control unit that directly performs output control of the effect device separately from the sub-control unit 91 is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41. The output pattern of the rendering device may be determined, and the output control unit may control the output of the rendering device based on the output pattern determined by the sub-control unit 91. In such a configuration, the sub-control unit 91 and the output control The output control of the rendering device is performed by both of the units.

  The effect control board 90 is composed of a microcomputer having a sub CPU 91a, a ROM 91b, a RAM 91c, and an I / O port 91d, and controls an effect, and a liquid crystal display 51 connected to the effect control board 90.

  The sub CPU 91a receives commands transmitted from the game control board 40, performs various controls for performing the effect, and directly or indirectly controls each unit of the control circuit mounted on the effect control board 90. .

  The sub-control unit 91 has an interrupt function similarly to the main control unit 41, generates an interrupt when receiving a command from the main control unit 41, and acquires the command transmitted from the main control unit 41. , Execute the command reception interrupt processing stored in the buffer. Further, the sub-control unit 91 generates an interrupt every time the number of input system clocks reaches a certain number, that is, at certain time intervals (about 2 ms), and executes a timer interrupt process (sub) described later. Further, unlike the main control unit 41, when an interrupt occurs based on the reception of a command, the sub-control unit 91 interrupts the timer interrupt process (sub) even during execution of the process. , A command reception interrupt process is executed, and even if interrupts that trigger the timer interrupt process (sub) occur simultaneously, the command reception interrupt process is executed with the highest priority. The backup power is also supplied to the sub-control unit 91 at the time of a power failure, and the data stored in the RAM 91c is retained while the backup power is supplied.

  In the slot machine 1 of the present embodiment, the payout rate of medals changes according to the set value. More specifically, the medal payout rate is changed by using a winning probability according to a set value in a lottery that affects the degree of advantage to a player, such as an internal lottery, a navigation stock lottery, and an additional lottery described later. The set value is made up of six levels from 1 to 6, with 6 being the highest payout rate and the payout rate decreasing as the value decreases in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is the highest for the player, and as the value decreases in the order of 5, 4, 3, 2, and 1, the advantage gradually decreases.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after turning on the setting key switch 37. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM is displayed as a display value on the setting value display 24, and the setting value can be changed by operating the reset / setting switch 38. Move to change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the set value display 24 is updated by one (when further operated from the set value 6, the set value is changed to 1). Return). Then, when the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned off, the determined display value (set value) is stored in the RAM of the main control unit 41, and the game shifts to a state in which the game can proceed.

  In order to confirm the set value, after the game is over, the setting key switch 37 may be turned on in a state where the bet amount is not set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM is displayed on the setting value display 24, thereby shifting to a setting check state in which the setting value can be checked. In the setting confirmation state, the progress of the game is not possible, and by setting the setting key switch 37 to the off state, the setting confirmation state ends, and the game returns to a state in which the game can proceed.

  In the slot machine 1 of the present embodiment, the main control unit 41 determines whether or not the voltage drop signal from the power interruption detection circuit 48 is detected every time the timer interrupt processing (main) is executed. When the determination process is performed and it is determined that the voltage drop signal is detected in the power failure determination process, the power interruption process (main) for setting data for determining whether the data in the RAM is normal at the next recovery is performed. Run.

  Then, the main control unit 41 returns the processing state of the main control unit 41 to the state before the power failure based on the data stored in the RAM, on condition that the data in the RAM is normal at the time of startup. However, if the data in the RAM is not normal, it is determined that the RAM is abnormal, the RAM abnormal error code is set in the register, the RAM is controlled to an abnormal error state, and the progress of the game is disabled. The progress of the game is to advance a series of processes constituting the game. In the case of a slot machine, the number of bets is set and the game can be started. Advancing the step of causing the reel to stop, deriving the display result, and the step of giving a value such as a medal according to the display result.

  Further, after the end of the setting change process, the main control unit 41 executes a main process of performing a process stepwise according to the progress of the game for each game unit. In the main process, the RAM is initialized for each game unit, and the RAM is also initialized at the end of the setting change process. Then, after the end of the setting change processing, the main processing is started from a stage before the processing of initializing the RAM in the main processing, and the initialization of the RAM after the end of the setting change processing and the game unit The initialization of each RAM can be performed by common processing.

  In the slot machine 1 of the present embodiment, a specified number of bets that can be set according to the game state is determined, and the game is performed on the condition that the specified number of bets is set according to the game state. Can be started. In the present embodiment, the pay line LN is activated when a prescribed number of bets is set according to the gaming state.

  In the present embodiment, when all the reels 2L, 2C, 2R are stopped, the activated pay line (in the present embodiment, all the pay lines are always activated. A winning combination is achieved when a combination of symbols called combinations is arranged on the winning line that has been formed (hereinafter, simply referred to as a winning line). The combination may be a combination of the same symbols or a combination including different symbols.

  The types of winning combinations are determined according to the state of the game, but can be broadly divided into small winning combinations with medal payout and re-starting so that the next game can be started without setting the number of bets. There are a gaming role and a special role accompanied by a transition to a gaming state advantageous to the player. Hereinafter, the small role and the replaying role are also collectively referred to as a general role. In order for the winning of each combination determined according to the gaming state to occur, it is necessary to win the internal lottery described later and set the winning flag of the combination in the RAM. Note that among the winning flags of these roles, the winning flags of the small role and the replaying role are valid only in the game in which the flag is set, and are invalid in the next game. The combination is enabled until the combination of the permitted combinations is completed by the flag, and is invalid in the game in which the combination of the permitted combinations is completed. That is, once the special combination winning flag is won, even if the combination of combinations permitted by the flag cannot be aligned, the winning flag is not invalidated and is carried over to the next game. Becomes

  Hereinafter, the internal lottery of the present embodiment will be described. In the internal lottery, the main controller 41 determines whether or not to permit winning of each of the above-mentioned roles before the display results of all the reels 2L, 2C, 2R are derived (specifically, the start switch 7). At the time of detection). In the internal lottery, first, when the start switch 7 is detected, a random number for the internal lottery (an integer from 0 to 65535) is obtained. Specifically, the value generated by the random number circuit and stored in the random number value register of the random number circuit is set in the lottery work assigned to the RAM. Then, for each combination determined according to the gaming state, according to the numerical data stored in the lottery work and the number of judgment values of each combination determined according to the current gaming state, the number of bets and the set value. It is determined whether or not a prize is allowed.

  In the internal lottery, the number of determination values determined according to the role to be subjected to the internal lottery, the current game state and the set value are sequentially changed to the random number value for the internal lottery (numerical data stored in the lottery work). If the result of the addition overflows, it is determined that the winning combination has been won. For this reason, the winning combination is determined based on the probability (the number of judgment values / 65536) according to the magnitude of the number of judgment values. Then, when the winning of any of the winning combinations is determined, the winning flag corresponding to the determined winning combination is set in the internal winning flag storing work assigned to the RAM.

  In the present embodiment, the main control unit 41 counts the game time, which is the time that has elapsed since the start of the game, each time the reel rotation is started, that is, the time elapsed from the start of the reel rotation. After the end of one game, when a predetermined number of bets is set by inserting medals or the like and the game start operation is performed in a state where the game start operation is enabled, the reel rotation of the previous game is started. If the game time from which the timing was started is equal to or longer than the specified time (4.1 seconds in this embodiment), that is, if the specified time has elapsed since the start of reel rotation of the previous game, no wait is generated. At that time, the rotation of the reel for the game in the game is started. On the other hand, after the end of one game, when a predetermined number of bets is set by inserting medals or the like and the game start operation is performed in a state where the game start operation is enabled, the reel rotation of the previous game is started. If the game time that started counting from the point in time is less than the specified time, that is, if the specified time has not elapsed since the start of reel rotation in the previous game, a wait is generated and the reel rotation is started at that point. Instead, the game waits until the game time that has started timing from the start of reel rotation of the previous game reaches a specified time, and starts reel rotation when the specified time is reached.

  In the present embodiment, the main control unit 41 performs control to output an external output signal indicating a game state, an error occurrence state, and the like. These external output signals are output to a hall device such as a hall computer through an external output board 1000 and an information providing terminal board of a game shop (hall) in which the slot machine 1 is installed.

  The main control unit 41 provides a medal IN signal indicating the number of medals used for setting the bet number, a medal OUT signal indicating the number of medals given to the player due to the occurrence of a prize, and an RB (gaming state advantageous to the player). An RB signal indicating that a regular bonus is being performed, a BB signal indicating that a game state is during a BB (big bonus) advantageous to the player, an ART signal indicating the start of an ART described later, and the front door 1b is being opened. , A setting change signal indicating that the mode is shifted to a setting change mode to be described later, an insertion error signal indicating an abnormality of the medal selector, and a payout error signal indicating an abnormality of the hopper unit 34.

  The external output board 1000 is provided with a relay circuit, a parallel-serial conversion circuit, and a terminal for each output signal, and is provided with a connector to be electrically connected to a circuit of the information providing terminal board. Among the signals output from the game control board 40, the medal IN signal, the medal OUT signal, the RB signal, the BB signal, and the ART signal are directly output as pulse signals to the information providing terminal board via the relay circuit. . On the other hand, the door opening signal, the setting change signal, the closing error signal, and the dispensing error signal are converted by a parallel-serial conversion circuit into security signals, which are serial signals that can be individually identified, and information is provided. Output to terminal board.

  Next, a command transmitted from the main control unit 41 to the sub control unit 91 will be described. In the present embodiment, the main control unit 41 instructs the sub-control unit 91 to insert a number of coins command, a credit command, a game status command, an ART status command, an internal winning command, a freeze command, a reel acceleration information command, and a stop operation command. , Number of sliding commands, stop command, game end command, winning number command, payout start command, payout end command, standby command, stop command, error command, return command, setting command, setting confirmation command, door command, operation detection Send multiple types of commands including commands. These commands are composed of 1-byte type data indicating the type of the command and 1-byte extended data indicating the content of the command. The sub-control unit 91 can determine the type of the command from the type data.

  The internal winning command is a command capable of specifying an internal lottery result, and is transmitted when the start switch 7 is operated to start the game. The internal winning command includes a first internal winning command and a second internal winning command, and a state in which a navigation notification is performed when a notification target role to be described later in the internal lottery has been selected. If so, the first internal winning command that can specify the type of the winning notification target role and the stop order that is advantageous for the player is transmitted, and if the navigation notification is not performed, the winning notification target role of the winning notification target role is transmitted. A second internal winning command is transmitted in which the type is identifiable but the stop order advantageous to the player is not identifiable.

  Since the game state command and the internal winning command are transmitted when the game is started by operating the start switch 7, it is possible to specify that the game is started by operating the start switch 7 by receiving these commands. It is.

  The stop operation command, the number of sliding frames command, and the stop command can specify whether the reel to be stopped is a left reel, a middle reel, or a right reel, and is associated with the stop operation of each reel. Since the command is transmitted every time the stop control is performed, by receiving these commands, it is possible to specify that any one of the reels has been stopped and the reel to be stopped.

  Since both the game end command and the winning number command are transmitted when the player presses the stop switch to stop the third stop reel and releases the stop switch, by receiving these commands, It is possible to specify that all the operations necessary to advance one game are completed.

  Next, the control of the effect performed by the sub-control unit 91 based on the command transmitted from the main control unit 41 to the effect control board 90 will be described. When receiving a command from the main control unit 41, the sub control unit 91 executes a command reception interrupt process. In the command reception interrupt processing, the command acquired from the command transmission line is stored in a reception buffer provided in the RAM 91c.

  In the timer interrupt processing (sub), the sub control unit 91 determines whether or not an unprocessed command is stored in the reception buffer. The control pattern table stored in the ROM 91b is referred to based on the command received in the step, and the liquid crystal display 51, the effect LED 52, the speakers 53 and 54, the reel LED 55, etc. are controlled based on the control contents registered in the control pattern table. Controls the output of various effect devices. In the control pattern table, for each of a plurality of types of effect patterns, a display pattern of the liquid crystal display 51 corresponding to the type of command, a lighting mode of the effect LED 52, an output mode of the speakers 53 and 54, a lighting mode of the reel LED 55, and the like. The control patterns of these effect devices are registered, and upon receiving the command, the sub-control unit 91 sets the control pattern of the control pattern registered in the control pattern table corresponding to the effect pattern set in the RAM 91c in the game. The control device refers to the control pattern corresponding to the type of the received command, and controls the output of the effect device based on the control pattern. As a result, an effect according to the effect pattern and the progress of the game is executed.

  The main control unit 41 can execute a navigation notification for changing the lighting mode of the game auxiliary display 12 so as to identifiably notify an operation mode (stop order, stop timing, etc.) that is advantageous to the player. Further, when the navigation notification is executed, the sub-control unit 91 displays the operation mode notified by the navigation notification by displaying the navigation image from the liquid crystal display 51 and outputting the navigation voice from the speakers 53 and 54. It is possible to execute a navigation effect to notify.

  Further, the navigation effect is executed over a period from the time when the start switch 7 is operated and the game is started to the time when the third stop operation is performed, but the first stop operation is performed according to the operation mode, A configuration in which the operation is terminated by performing two stop operations may be employed.

  A privilege that is advantageous to the player is a right that enables the player to shift to an advantageous state (a win in a lottery that determines whether or not to generate an advantageous state, a prize to shift to the advantageous state) Permitted, etc.), a right to be notified of an operation mode advantageous to the player, a right to be controlled to a gaming state having a high expected value to which a gaming value is given, and a gaming in which the current gaming state is advantageous to the player It may be a privilege directly advantageous to the player, such as the right to be notified of the state or not, the period of controlling to the advantageous state (the number of fixed games, the average value of the number of games fluctuating depending on the ending condition, etc.). Although it is not directly advantageous to the player, the privilege may be indirectly advantageous to the player, such as a condition for obtaining a privilege on the Internet.

The entire reel unit 2 is a replacement part.

  In such a slot machine 1, when a model is changed from an old model to a new model or a model is changed to a model having a different specification, the gaming machine maker collects the existing slot machine from the gaming arcade and exchanges replacement parts. In some cases, a gaming machine maker delivers replacement parts to a game arcade, and the gaming arcade performs replacement work on the replacement parts. Therefore, if the number of replacement parts as described above increases, replacement work becomes complicated.

  Therefore, in the slot machine 1 of the present embodiment, the front door 1b that enables the housing 1a to be opened and closed is configured by a plurality of unit members such as a common unit 200, an upper opening and closing unit 210, and a lower opening and closing unit 220. By replacing both the upper opening / closing unit 210 and the lower opening / closing unit 220, a large number of replacement parts can be easily replaced collectively.
