  The present invention relates to a gaming machine such as a slot machine or a pachinko machine.

  2. Description of the Related Art A gaming machine (a spinning machine, slot machine) having a plurality of spinning cylinders with symbols arranged on the outer peripheral surface is known. This type of gaming machine gives a certain game value to a game medium (medal) and performs a game for acquiring such a game medium. In addition, this type of gaming machine has an internal lottery triggered by the player's rotation start operation and starts rotation of a plurality of spinning cylinders, and a mode according to the result of the internal lottery as a player's stop operation trigger. In order to stop multiple cylinders. The game result is determined by the symbol combination displayed on the winning determination line in a state where the plurality of spinning cylinders are stopped, and medals are paid out according to the game result.

  A variety of presentation devices such as liquid crystal display devices (liquid crystal panels), production display lamps (electric decorations), and sound generators (sound devices, speakers) are provided in gaming machines as devices that play a role in enhancing the interest of players. It has been. In addition, there may be provided a movable accessory (movable body) that includes a movable part and produces an effect by the movement of the movable part.

Also, synchronize with the clock signal between the sub control board and the CPU of each board, and send data to the destination specified by the address via the serial data line, or receive data from the source specified by the address To do. An I2C bus can be used as the bidirectional serial bus wiring. Patent No. 4480094 gazette Pachislot effect control board (sub control board) and the sub relay board that controls the illumination arranged on the front of the front door are connected by serial communication, and serial-parallel conversion is performed in the sub relay board Thus, the communication board is connected in parallel communication. On the other hand, it is described that the effect control board and the liquid crystal control board are connected in parallel communication.

The sub board performs an effect according to the progress of the game in accordance with a command from the main board. A main board, a sub board, a production device, and the like are integrated to form a gaming machine.

  By the way, in a gaming machine with a separate casing, the components of the gaming machine are divided into a plurality of blocks, and some of them are elements common to a plurality of models. That is, the separated type gaming machine includes a unique block (model-specific block) that is different for each model and a block that is used in common. Commonly used blocks may be further divided into blocks that can be exchanged (scheduled to be exchanged) and blocks that are not exchanged.

  As described above, it is desirable to optimize the plurality of blocks having different properties by changing the communication method for controlling the rendering device provided in them. For example, for a model-specific block, a communication method that requires complicated processing but is versatile and capable of communicating with various boards is adopted. It is conceivable to adopt a communication method that is easy to process. Further, when replacing the blocks, it is only necessary to change some of the harnesses (wirings), and it is desirable that the harnesses between the blocks that are not replaced can be used continuously.

  In view of the above, an object of the present invention is to provide a gaming machine having a separate housing that employs an optimum communication method for each block and that can continuously use a harness between blocks that are not replaced.

The present invention relates to a model-specific block unique to each model of the gaming machine, a first block (lower door block) commonly used for each case, a replaceable second block (upper door block), and the model A gaming machine comprising a unique block, a processing unit (sub-board) that controls the first block and the second block, and a housing of a gaming machine that houses the model-specific block, the first block, and the second block In
The model-specific block, the first block, and the second block are model-specific for connecting the processing unit and predetermined devices included in the model-specific block, the first block, and the second block, respectively. Including a relay board, a first relay board and a second relay board (slave board),
An address is determined in advance for the model-specific relay board,
The processing unit includes a model-specific input / output terminal that outputs or inputs a serial signal, a first output terminal and a first input terminal, a second output terminal and a second input terminal,
The model-specific input / output terminal is connected to the model-specific relay board by a model-specific harness,
The first output end and the first input end are connected to the first relay board by a first harness,
The second output end and the second input end are connected to the second relay board by a second harness,
The processor is
When transmitting a serial signal through the model-specific input / output terminal, specify an address of the model-specific relay board to which the serial signal is transmitted, transmit the serial signal to the model-specific relay board related to the address, and transmit after transmission When the serial signal is received through the model-specific input / output terminal, an address of the model-specific relay board that receives the serial signal is designated, and the serial signal is sent from the model-specific relay board related to the address. A model-specific transmission / reception processing unit that receives and notifies the end of reception transmission after reception;
A first transmission processing unit for generating a serial signal to be transmitted from the first output end to the first relay board;
A first reception processing unit for converting a serial signal received from the first relay board at the first input terminal into a parallel signal;
A second transmission processing unit for generating a serial signal to be transmitted from the second output end to the second relay board;
A second transmission / reception processing unit for converting a serial signal received from the second relay board at the second input end into a parallel signal;
The model-specific relay board includes a relay (slave) transmission / reception processing unit that performs reception processing and transmission processing according to the address from the model-specific transmission / reception processing unit.

The first relay board receives serial communication from the first output terminal, and serially inputs inputs of a semiconductor element (LED driver, motor controller) that controls the device based on the received data and a plurality of predetermined sensors. Including a semiconductor element that converts the signal into a first input terminal.
The second relay board receives serial communication from the second output terminal, and controls a semiconductor element (LED driver, controller) that controls the device based on the received data, and inputs a plurality of predetermined sensors as serial signals. And a semiconductor element that is sent to the second input terminal.

  In the case of a separate type of gaming machine, the communication content with the model-specific block is dependent on the model due to the fact that the communication method for the model-specific device is different, and is different for each model. Therefore, versatility is required for the communication method with the model-specific block. On the other hand, the communication method for other blocks is limited to a predetermined one. However, even in this case, it is necessary to consider that replacement is planned for some blocks.

  In consideration of these points, the present invention adopts an optimum communication method.

  Since the processing unit (sub-board) communicates with the model-specific block using the model-specific input / output terminal, the model-specific transmission / reception processing unit (master) performs bidirectional communication by designating an address. Can communicate with. For example, since the communication partner is specified by the address, multiple model-specific relay boards (slave boards) can be connected to the model-specific harness, and the number and type of data to be transmitted and received can be set flexibly by performing bidirectional communication. Can do.

  In the communication with the second block, the processing unit transmits the serial data to the second relay board using the second output terminal, and uses the second input terminal to transmit the second data. 2 The transmission / reception processor receives serial data from the second relay board. The communication is unidirectional, the processing is simple, and the burden on the processing unit is small. The second relay board can perform reception processing and transmission processing by a semiconductor element (IC), and there is no need to create a program. On the other hand, the model-specific block requires a processing unit (CPU or the like) and a program for operating it. By not requiring versatility in communication with the second block, the processing load on the processing unit is reduced, the program for the second relay board is unnecessary, and cost reduction can be realized.

  In addition, for each relay board, the processing unit includes the model-specific input / output terminal, the first output terminal and the first input terminal, the second output terminal and the second input terminal. Since the model-specific harness, the first harness, and the second harness are connected to each other, it is only necessary to change the model-specific harness when applying to different models. The first block can be commonly used for different models. When replacing the second block, it is only necessary to replace the second harness. When replacing the second block, other harnesses are not affected. Thus, the gaming machine according to the present invention can easily perform block exchange.

  As described above, according to the present invention, the model-specific block unique to each model of the gaming machine, the first block commonly used for each housing, the replaceable second block, and the model-specific block In a gaming machine comprising a processing unit for controlling the first block and the second block, it is optimal for data transmission / reception between the processing unit and the model-specific block, the first block, and the second block. The communication method could be adopted.

Only one command flows from the main board 10 to the sub board 20, and conversely, no command is issued from the sub board 20 to the main board 10.

  Hereinafter, the main board and the sub board will be described in detail.

<Main board>
The main board 10 includes the bet switch BET, the start switch 134, the stop button 140, the reel (rotating cylinder) unit 203, the setting change switch SSW, the hopper driving unit 80, the hopper 81, and the number of medals paid out from the hopper 81. A medal detection unit 82 for counting (these constitute the hopper device 121 described above) is connected.

  Further, medal sensors S1 and S2 of the medal selector 1 are connected to the main board 10.

  The medal selector 1 is provided with medal sensors S1 and S2 for counting medals. The medal sensors S1 and S2 are attached to the downstream side (near the exit) of a medal passage (not shown) provided in the medal selector 1 (the upstream side of the medal passage communicates with the medal insertion port 132). The two medal sensors S1 and S2 are provided side by side at a predetermined interval along the medal traveling direction. The medal sensors S1 and S2 are, for example, photointerrupters that have a light emitting portion and a light receiving portion that face each other, are formed in a U-shaped cross section, and are positioned so that the detection optical axis faces the medal passage from above. . Each photo interrupter detects the passage of a medal sent without being blocked on the way. The reason why two photo interrupters are adjacent is not only to detect the number of medals but also to monitor whether or not the passage of medals is normal. That is, by providing two photo interrupters adjacent to each other, it is possible to detect the passing speed and passing direction of medals, thereby detecting not only the number of medals but also an illegal act moving in the reverse direction.

  The reel unit 203 includes three spinning cylinders 40a to 40c, stepping motors 155a to 155c that respectively rotate these, and spinning cylinder position detectors (index sensors) 159a to 159c that detect their positions, respectively (note that The stepping motors 155a to 155c may be simply referred to as a motor 155 or a motor).

  Based on the reference position signal detected by the index sensor 159 every time each of the rotating cylinders 40a to 40c makes one rotation, the rotating cylinder control means 1300 starts from the reference position (a frame specified by an index (not shown)) of the rotating cylinder 40. Is obtained (by counting the number of rotation steps of the rotation shaft of the step motor), the current rotation state of the drum 40 can be monitored. That is, the main substrate 10 can obtain the position of the rotating drum 40 when the stop button 140 is operated by obtaining the rotation angle from the reference position of the rotating drum 40.

  In the following description, reference numeral 40 is used to indicate any one or a plurality of spinning cylinders, and reference numerals 40a to 40c are used to separately indicate three spinning cylinders.

  The hopper driving unit 80 rotates an unillustrated rotating disk of the hopper 81 and performs an operation of paying out medals of the payout number instructed by the main board 10. The gaming machine includes a medal detection unit 82 that operates every time a medal is paid out, and the main board 10 receives a medal actually paid out from the hopper 81 based on an input signal from the medal detection unit 82. You can manage the number.

  The insertion accepting unit (insertion accepting means) 1050 receives the outputs of the medal sensors S1 and S2 of the medal selector 1, accepts the insertion of medals for each game, and based on the insertion of medals corresponding to the prescribed number of insertions. Then, a process of permitting the start operation of the first to third cylinders for the start switch 134 is performed. Note that the pressing operation of the start switch 134 is an opportunity to start the rotation of the first cylinder to the third cylinder, and is an opportunity to execute the internal lottery. Also, a prescribed number of throws is set according to the gaming state, the prescribed number of throws is set to 3 in the normal state and the bonus established state, and the prescribed number of throws is set to 1 in the bonus state.

  When medals are inserted, the inserted medals are set to the inserted state up to a specified number of insertions according to the gaming state. Alternatively, when the bet switch BET is pressed in a state where medals have been credited to the gaming machine, the credited medals are set to the inserted state by limiting the prescribed number of insertions according to the gaming state. The main board 10 controls whether or not to accept a medal. From the time when the start switch 134 is pressed and the rotation of each cylinder starts (game start time), when the three stop buttons 140 are pressed and the rotation of each cylinder stops (when the medal payout is completed when winning) (game) When the medal is not accepted (when it is not permitted), the medal sensor S1, S2 does not count the medal and is returned as it is. . Similarly, the main board 10 controls the validity / invalidity of the bet switch BET according to whether or not the medal insertion is accepted. In addition, the bet switch BET is valid from the end of the game to the start of the game, but during other periods (when pressing of the BET switch is not permitted), the bet switch BET is pressed. Even it is ignored.

  The main board 10 incorporates random number generating means 1100. The random number generation means 1100 is a means for generating a random number for lottery. The random value can be generated based on, for example, a count value of an increment counter (a counter that counts numerical values so as to circulate a predetermined count range). In this embodiment, the “random number value” is not only a value that is randomly generated in a mathematical sense, but even if the generation itself is regular, the acquisition timing and the like are irregular. Includes a value that can function as a random number.

  The internal lottery means 1200 performs an internal lottery in which the player determines whether or not the winning combination is based on a start signal from the start switch 134. That is, a lottery table selection process for selecting a lottery table (not shown) stored in a memory (not shown) of the main board 10, a random number determination process for determining the winning of a random number obtained from the random number generating means 1100, The lottery flag setting process for setting a flag to that effect when a big win or the like is won by the determination result is performed.

  In the lottery table selection process, a lottery table (not shown) stored in a storage unit (ROM) (not shown) is used to determine which lottery table is used for internal lottery. In the lottery table, for each of a plurality of random values (for example, 65536 random values from 0 to 65535), replay, small role (bell, cherry), regular bonus (RB: bonus), and big bonus (BB :), etc., are associated with each other. In addition, a normal state, a bonus establishment state, and a bonus state can be set as the gaming state, and a replay lottery state, a replay low probability state, and a replay high probability state can be set as replay lottery states.

  The lottery table selection process allows the contents of the lottery to be set within a predetermined range (the probability of winning can be increased or decreased), and the setting work is performed by the store in the hall where the gaming machine is installed. . The switch used in this setting operation is a setting change switch SSW.

  A normal gaming machine includes a plurality of (for example, six) lottery tables having different lottery probabilities such as BB, RB, and small roles in advance. In the lottery of gaming machines, one of the plurality of lottery tables is set, and the winning / losing determination by lottery is made based on the set lottery table. Changing a setting relating to which of a plurality of lottery tables is used is referred to as a setting change (hereinafter referred to as “setting change”).

  Conventionally, in a gaming machine such as a slot machine, when changing a setting value (usually 1 to 6), the door of the gaming machine is opened, and a setting change key is set as a key switch of a setting change switch SSW provided on the main board 10. With the key inserted and the key switch turned on, the game machine is turned on so that the setting can be changed. Every time the setting change button (push button) of the setting change switch SSW is pressed, 7 segments The set value displayed on the display unit is incremented to cyclically change the values from 1 to 6, and the desired set value is operated by operating the start switch when the desired set value is displayed on the display unit. Is confirmed.

  In the random number determination process, on the basis of the start signal from the start switch 134, a random number value (lottery random number) is acquired for each game from random number generation means (not shown), and the lottery table is referred to for the acquired random number value. To determine whether or not they have won the role.

  In the lottery flag setting process, the lottery flag of the winning combination determined to be won based on the result of the random number determination process is changed from the non-winning state (first flag state, off state) to the winning state (second flag state, on Status). When two or more types of winning combinations are won, a lottery flag corresponding to each of the two or more types of winning winning combinations is set to the winning state. The lottery flag setting information is stored in storage means (RAM).

  A lottery flag (possible carryover flag) that can carry over the winning state for the next game until winning, and a lottery flag that is reset to the non-winning state without bringing the winning state to the next game regardless of winning Carry-over impossible flag) may be provided. In this case, there are a regular bonus (RB) and a big bonus (BB) as a combination to which the former carry-over possible flag is associated, and other combinations (for example, small role, replay) correspond to the latter carry-over impossible flag. It is attached. In other words, in the lottery flag setting process, when a regular bonus is won by internal lottery, the winning state of the regular bonus lottery flag is carried over until the regular bonus is won, and when a big bonus is won by internal lottery, A process of carrying over the winning state of the flag until the big bonus is won is performed. At this time, the main board 10 determines whether or not a role other than the regular bonus and the big bonus (small role and replay) is used even in a game in which the winning state of the regular bonus or big bonus lottery flag is carried over by the internal lottery function. An internal lottery is performed. In other words, in the lottery flag setting process, in a game in which the winning state of the regular bonus lottery flag is carried over, if a small role or replay is won in the internal lottery, the regular bonus lottery flag and the internal lottery already won In a game in which the lottery flags corresponding to two or more types of winning combinations or replay lottery flags won in the win state are set to the winning state and the winning state of the big bonus lottery flag is carried over, it is small in the internal lottery When a winning combination or replay is won, a lottery flag corresponding to two or more kinds of winning combinations including a big bonus lottery flag that has already been won and a small bonus or replay lottery flag that has been won in an internal lottery is set to a winning state. Set.

  The spinning cylinder control means 1300 rotates the first to third cylinders by a stepping motor based on a start signal generated by the player pressing the start switch 134 (rotation start operation), and the first cylinder -Depressing (stopping) the three stop buttons 140 corresponding to the rotating cylinders in a state where the rotation speed of the third cylinder reaches a predetermined speed (about 80 rpm: a rotational speed of about 80 rotations per minute). In addition to performing control to permit the operation), control is performed to stop the first to third cylinders driven to rotate by the stepping motor in accordance with the lottery flag setting state (internal lottery result).

  In addition, when the player presses the three stop buttons 140 in a state where the pressing operation (stop operation) with respect to the three stop buttons 140 is permitted (validated), Based on the signal, the supply of the drive pulse (motor drive signal) to the stepping motor of the reel unit 203 is stopped, thereby controlling each of the first to third drums.

  That is, each time the three stop buttons 140 are pressed, the spinning cylinder control means 1300 determines the stopping position of the spinning cylinder corresponding to the pressed button among the first to third cylinders. Thus, control is performed to stop the spinning cylinder at the determined stop position. Specifically, referring to a stop control table (not shown) stored in the storage means (ROM), the first time corresponding to the pressing timing, pressing order, etc. of the three stop buttons (mode of stop operation) A stop position of the cylinder to the third cylinder is determined, and control is performed to stop the first cylinder to the third cylinder at the determined stop position.

  Here, in the stop control table, the positions of the first cylinder to the third cylinder (pressing detection position) at the time when the stop button 140 is operated, and the actual stop positions (or pressing detection of the first cylinder to the third cylinder). Correspondence with the number of sliding frames from the position) is set. The number of sliding symbols is a symbol that passes through the reference position between the operation of the stop button 140 and the rotation stop of the corresponding rotating cylinder when a specific symbol that can be visually recognized from the game display unit at the time of stopping the rotating drum is used as the reference position. The number of Since the turning cylinder control means 1300 stops each turning cylinder within 190 ms from the operation of each stop button 140, the number of sliding frames is in the range of 0 to 4 (however, 80 revolutions / minute, (In the condition of the number of symbols = 21). Depending on the setting state of the lottery flag, a stop control table for determining the stop positions of the first cylinder to the third cylinder may be prepared.

  As described above, the spinning cylinder control unit 1300 is based on the reference position signal detected by the index sensor 159 every time the rotating cylinder makes one rotation, from the reference position of the spinning cylinder (the frame detected by the reel index). By obtaining the rotation angle (the number of rotation steps of the rotation shaft of the step motor), the current rotation state of the rotating drum can be monitored. That is, the main board 10 can obtain the position of the rotating cylinder when the stop button 140 is operated by obtaining the rotation angle from the reference position of the rotating cylinder.

  The spinning cylinder control unit 1300 performs so-called pull-in processing and kicking processing as control for stopping the spinning cylinder. The pull-in process is a control for stopping the spinning cylinder so that the symbol corresponding to the combination whose lottery flag is set to the winning state is stopped on a valid winning determination line (so that the winning combination can be won). It is processing. On the other hand, the kicking process means that the symbol corresponding to the combination for which the lottery flag is set to the non-winning state does not stop on a valid winning determination line (so that a non-winning combination cannot be won) Is a control process for stopping the process. That is, in the gaming machine of the present embodiment, the lottery flag setting state, the stop button 140 pressing timing, the pressing order, and the stop position of the spinning cylinder that has already stopped (in the display pattern) in order to realize the pull-in processing and kicking processing. The stop control table is set so that the stop position of each cylinder changes according to the type). In this way, the main board 10 can stop the symbol of the combination for which the lottery flag is set to the winning state in a winning form, while the symbol of the combination for which the lottery flag is set to the non-winning state is in the winning form. Control is performed to stop the first to third cylinders so as not to stop.

  In the gaming machine of the present embodiment, the first to third drums are controlled to stop the rotating drum corresponding to the pressed stop button within 190 ms from the time when the stop button 140 is pressed. Is set to That is, in the stop control table for determining the stop position of each rotating cylinder, the number of frames required from when the stop button 140 is pressed until each cylinder stops is in the range of 0 to 4 frames (predetermined pull-in range). Is set in

  The winning determination means 1400 performs a process of determining whether or not a winning combination has been won based on the stopping modes of the first to third cylinders. Specifically, referring to the winning determination table stored in the storage means (ROM), the symbol combination displayed on the winning determination line when all of the first to third cylinders are stopped. It is determined whether or not this is a predetermined winning combination form.

  The winning determination means 1400 executes a winning process based on the determination result. As a process at the time of winning a prize, for example, when a small role wins, the hopper 81 is driven to perform a medal payout control process, or a credit is increased (a predetermined maximum number is increased to 50, for example, When the replay is won, a replay process is performed. When a big bonus or a regular bonus is won, a game state transition control process for shifting the game state is performed.

  The payout control means 1500 performs payout control processing relating to the payout of medals according to the game result. Specifically, when a small combination wins, the number of medals to be paid out in the game is determined based on a payout predetermined for each combination, and the medals corresponding to the determined number of payouts are determined by the hopper driving unit 80. Then, the hopper 81 is driven to pay out. At this time, a current flows through a motor (not shown) built in the hopper 81.

  When medal credits (internal storage) are permitted, instead of actually paying out medals by the hopper 81, the number of credits stored in a credit storage area (not shown) of the storage means (RAM) (not shown) A credit addition process for adding the number of payouts to the number of credited medals is performed to virtually pay out medals.

  When the replay is won, the replay processing means 1600 performs a replay process (regame process) for setting the same preparatory state as the previous game without requiring insertion of medals owned by the player for the next game. When a replay wins, an automatic insertion process is performed in which the same number of medals as the previous game is automatically set to the insertion state without using the player's own medals (including credit medals). The game machine is set in a state of waiting for a rotation start operation (pressing operation of the start switch 134 by the player) in the next game in a state where the same winning determination line as the previous game is validated.

  The replay processing unit 1600 may perform control to change the winning probability of replay in the internal lottery under a predetermined condition. For example, when a predetermined turn is displayed when the spinning cylinder is stopped by operating the stop button 140, the winning probability of replay varies. The replay lottery states include a replay no lottery state in which replay is excluded from the internal lottery, a replay low probability state in which the replay winning probability is set to about 1 / 7.3, and a replay winning probability of about 1 / A plurality of lottery states such as a high replay probability state set to 6 can be set.

  The error processing unit 1700 determines an error of the gaming machine based on the outputs of a door opening / closing detection sensor (not shown), the medal sensors S1 and S2, and the medal detection unit 82, and notifies that when it determines that there is an error. To a predetermined state (for example, a state in which no operation is accepted).

  A door open / close detection sensor (not shown) is a sensor that detects that the front door 130 (the upper door 130U and the lower door 130L) is closed, and is an electrical switch such as a micro switch or a contact. When the front door 130 (upper door 130U, lower door 130L) is closed, the switch is turned on (or turned off) by the action part of the switch contacting the back side of the front door 130 (upper door 130U, lower door 130L). When the front door 130 (upper door 130U, lower door 130L) is opened, the action part is separated and turned off (or turned on). The door opening / closing detection sensor may be an optical sensor such as a photo interrupter. The medal sensors S1 and S2 and the medal detection unit 82 have been described above.

Specifically, the error processing unit 1700 performs the following operation.
When an opening of the front door 130 (upper door 130U, lower door 130L) is detected based on the output of a door opening / closing detection sensor (not shown), error processing is performed.
-Based on the outputs of the medal sensors S1 and S2, the reverse flow of the medals (the detection order of the sensors S1 and S2 is reversed), the medal retention (the detection times of the sensors S1 and S2 are longer than a predetermined threshold) When error is detected, error processing is performed.
Based on the output of the medal detection unit 82, the medal clogging (the detection time of the medal detection unit 82 is longer than a predetermined threshold), hopper empty (the medal detection unit despite operating the hopper driving unit 80) When 82 detects no medal), error processing is performed.

  When the error processing unit 1700 determines that an error has occurred as described above, the error processing unit 1700 notifies the fact and sets the gaming machine to a predetermined state (error state). This state is canceled by a reset switch (not shown). The reset switch is provided on the panel of the power supply unit 205, for example.

  There are also errors that occur in the sub-board 20. Although this error does not result in an inoperable state, the liquid crystal display device or the like can notify that an error has occurred due to the processing of the sub-board 20 itself. The error occurs, for example, when an invalid command is received (including when the encrypted command cannot be correctly decrypted), and the error is canceled by the reset switch (from the main board 10 to the sub board 20). Reset command).

  Further, the main board 10 may perform control to shift the gaming state between the normal state, the bonus establishment state, and the bonus state (gaming state transition control function). As the game condition transition condition, one condition may be defined, or a plurality of conditions may be defined. When a plurality of conditions are established, transitioning the gaming state to another gaming state based on the fact that one of the plurality of conditions is satisfied or all of the plurality of conditions are satisfied Can do.

  The normal state is a game state corresponding to the initial state among a plurality of types of game states, and a transition from the normal state to the bonus establishment state is possible. The bonus establishment state is a gaming state that shifts when a big bonus or a regular bonus is won in the internal lottery. In the bonus establishment state, when the big bonus is won in the internal lottery in the normal state, the lottery flag corresponding to the big bonus is maintained in the winning state until the big bonus is won, and the regular bonus is won in the internal lottery in the normal state Until the regular bonus is won, the lottery flag corresponding to the regular bonus is maintained in the winning state. In the bonus state, it is determined whether or not the end condition is satisfied based on the total number of medals paid out by the bonus game, and medals exceeding a predetermined payout limit number are paid out according to the type of bonus won. The bonus state is terminated and the gaming state is returned to the normal state.

  The reel unit 203 includes three spinning cylinders 40a to 40c, and one stepping motor 155a to 155c is attached to each of the three spinning cylinders 40a to 40c. The stepping motor 155 includes a gear-shaped iron core or permanent magnet as a rotor (rotor), a plurality of windings (coils) as a stator (stator), and is rotated by switching windings through which current flows. It is. That is, a current is passed through the windings of the stator to generate a magnetic force, and the rotor is rotated by attracting the rotor. Since the rotation axis can be stopped at a specified angle, it is used to drive the rotation of the slot machine. A plurality of windings constitute one phase. As the number of phases, for example, there are two (two phases), four (four phases), and five (five phases).

  The stepping motor can change its characteristics (excitation mode changes) by changing the way of applying current to the windings of each phase. The two-phase type is as follows.

• Single-phase excitation Always allow current to flow through only one phase of the winding. Positioning accuracy is good.

・ Two-phase excitation
Current flows in two phases. An output torque approximately twice that of single-phase excitation can be obtained. The positioning accuracy is good and the stationary torque is large when stopped, so that the stop position can be held reliably.

・ One-two-phase excitation
A current is passed by alternately switching between one phase and two phases. Since the step angle can be halved in the case of one-phase excitation and two-phase excitation, smooth rotation can be obtained.

  Note that “driving” a stepping motor includes rotating the motor by the above-described excitation and exciting each phase in order to stop at a desired position and hold the position.

  Regarding driving of the spinning cylinders 40a to 40c of the slot machine, for example, a four-phase stepping motor having a basic step angle of 1.43 degrees is used, and one-two-phase excitation is adopted as a pulse output method.

  10CG is a command transmitter that transmits a command to be sent to the sub-board 20. This command includes a command related to winning combination information, a command related to information on the number of inserted medals and the number of credits (stored number). Specifically, the command transmission unit 10CG is realized by the CPU executing a program written in advance in a ROM mounted on the main board 10. The command transmission will be described later.

<Sub-board>
Connected to the sub board 20 are liquid crystal panels LCD1 and LCD2, LEDs (LED boards) 202B and 202L, a speaker SP, a bass speaker SPL, a solenoid SN, motors MU and ML, sensors SENU and SENL, and a switch SW. The LEDs 202B and 202L incorporate a latch that acquires and holds data and an LED that is an electric decoration (the LED may be provided outside the substrate). These components are controlled by the sub-board 20, and are an output device that produces effects by video, light, sound, and movement of the movable body, or an input device or player for detecting the movement of the movable body. It is an input device which receives operation by.

  The sub-board 20 drives a video controller (VDC) for controlling the liquid crystal panels LCD1 and LCD2, a speaker SP, a sound controller for generating sound by driving a bass speaker SPL, a solenoid SN, motors MU and ML. It has a built-in drive circuit.

  The components such as the liquid crystal panel described above, except for the bass speaker SPL, correspond to the model-specific block BB and the upper door block BU and the lower door 130L provided corresponding to the upper door 130U built in the slot machine housing 120. The lower door block BL is provided in a distinguishable manner.

  In the example of FIG. 3, the model-specific block BB includes the solenoid SN and the LED 202B, the upper door block BU includes the liquid crystal panel LCD1, the motor MU, and a sensor SENU that detects the operation of the movable body thereby, and the lower door block BL is , A liquid crystal panel LCD2, a speaker SP, an LED 202L, a motor ML, a sensor SENL for detecting the operation of the movable body thereby, and a switch SW such as a cursor key. The entire liquid crystal panel LCD2 is configured to be slightly movable back and forth by the motor ML, and the player may be able to perform an operation of pushing the liquid crystal panel LCD2 in a state where the liquid crystal panel LCD2 is moved forward. In this case, the switch SW of the lower door block BL includes a switch for detecting depression of the liquid crystal panel LCD2.

<Command transmission from main board to sub board>
The sub-board 20 receives a command from the main board 10 and performs processing such as rendering according to the command. Only one command flows from the main board 10 to the sub board 20, and conversely, no command is issued from the sub board 20 to the main board 10.

  The sub board 20 generates a command (display command, drawing command) for displaying a predetermined screen on the liquid crystal panels LCD1 and LCD2, for example, in accordance with a command from the main board 10. For example, when performing an effect by animation or the like, a large number of commands are continuously transmitted one after another.

  In FIG. 3, 20 CR is a command receiving unit that receives commands received from the main board 10. Specifically, the command receiving unit 20CR is realized by the CPU executing a program written in advance in a ROM mounted on the sub-board 20.

  As the above-mentioned command, there is a command for performing an effect suggesting the winning contents by the software on the sub-board 20 side. For example, as shown in the following AT, a suggestion for obtaining a ball is displayed on a liquid crystal display device so as to provide a player's operation convenience (assist). The suggestion is not always issued, but in specific cases.

  The gaming machine includes an effect display device including a liquid crystal display device, a speaker, a display lamp, and the like. This effect display device is controlled by the sub-board 20 to notify the player of a prize or the like, or in a so-called assist time (AT), the base itself teaches the user with some action during a certain game with some action. It is for doing. (Assist Time (AT): Even if a specific small role is established, the player will not be refunded if the reels are not aligned. After the big bonus ends (or when it is established) Alternatively, a lottery of assist time is drawn at any other opportunity, and if this is won, the player is instructed to perform an operation with some action for aligning specific small roles during a certain game)

  The command receiving unit 20CR receives a command received from the main board 10. For example, a command received as serial data is input to a serial-parallel converter (shift register), and is output every certain data (for example, 8 bits). The output data is transferred to the CPU of the sub-board 20 as a command, and is interpreted and executed.

Next, the game processing in the main board 10 will be described with reference to FIG.
Generally, in a gaming machine, one game is started from the insertion of medals (insertion of credits) until the end of payout (or until the increase in the number of credits is completed). There is a rule that it is not possible to proceed to the next game until one game is finished.

  First, when a prescribed number of medals are inserted, the start switch 134 is activated, and the processing of FIG. 4 is started.

  In step S1, the start switch 134 is turned on by operating the start switch 134. Then, the process proceeds to the next step S2.

  In step S2, a lottery process is performed by the main board 10. Then, the process proceeds to the next step S3.

  In step S3, the rotation of the first reel to the third reel starts. Then, the process proceeds to the next step S4.

  In step S4, when the stop button 140 is operated, the stop button 140 is turned ON. Then, the process proceeds to the next step S5.

  In step S5, rotation stop processing is performed on the reel corresponding to the pressed stop button 140 among the first to third reels. Then, the process proceeds to the next step S6.

  In step S6, it is determined whether or not the operation of the stop button 140 corresponding to the three reels has been performed. If it is determined that all three stop buttons 140 corresponding to the three reels have been operated, the process proceeds to the next step S7.

  In step S7, it is determined whether or not the winning symbols corresponding to the lottery flag are aligned on the effective winning line while the lottery flag is established, that is, whether or not the winning is confirmed. If it is determined that the winning is confirmed, the process proceeds to the next step S8. If the winning is not confirmed, no medals are paid out even if the lottery flag is established.

  In step S8, medals corresponding to winning symbols are paid out.

  The process from the insertion of the medal to the completion of the execution of step S8 is one game. When the standby process in step S8 ends, the process returns to the beginning of the flowchart. In other words, the next game is possible (transition to the next game).

  FIG. 5 is a block diagram showing connections of sub-boards, slave boards (relay boards), devices such as LEDs, solenoids, motors, and sensors (photosensors, switches, etc.) according to the embodiment of the invention. FIG. 5 is a block diagram of the connection system according to the embodiment of the present invention extracted from the block diagram of FIG. In FIG. 5, the same or corresponding parts as those in FIG.

  Of the elements shown in FIG. 5, the slave boards 206BU and 206BL are implemented by hardware such as an IC. The I2C transmission / reception processing unit 207 and the transmission / reception processing unit 208 of the slave board 206BB are stored in a ROM mounted thereon. This is realized by a CPU or the like executing a program written in advance. The transmission processing units 209T and 210T and the reception processing units 209R and 210R are realized by either hardware such as an IC or software.

  In FIG. 5, the sub-board 20 is included in the upper door block BU, but this is an example. For example, the sub-board 20 may be included in the lower door block BL, or may be provided separately from the model-specific block BB, the upper door block BU, and the lower door block BL.

  In the gaming machine according to the embodiment of the invention, I2C (Inter-Integrated Circuit) or synchronous serial method is used as a control communication method from the sub-board 20 to a slave board (relay board) that controls devices such as an accessory or electrical decoration. Serial communication is used. As the number of controlled objects, lighting, and other devices increases, the sub board connects to the slave board via serial communication, performs serial-parallel conversion on each slave board, and plays a role from each slave board. It is connected to devices such as objects and lighting.

  That is, in the gaming machine according to the embodiment of the invention, I2C is used as the communication method between the sub-board 20 and the model-specific block BB. Since the configuration of the electrical member of the model-specific block BB changes for each model, versatile bidirectional communication is adopted. The communication system between the sub-board 20 and the upper door block BU uses synchronous serial. Since the reel unit 203 is to be replaced at the same time when the reel unit 203 is replaced, a harness HBU dedicated to the upper door block BU is provided. The communication system between the sub-board 20 and the lower door block BL uses synchronous serial. Since it is a remaining common part, a harness HBL dedicated to the lower door block BL is provided.

  BB is a model-specific block unique to each model of gaming machine. BL is a lower door block (first block) used in common for each housing. BU is a replaceable upper door block (second block).

  The model specific block BB, the lower door block BL, and the upper door block BU include a slave board (model specific relay board) 206BB, a slave board (first relay board) 206BL, and a slave board (second relay board) 206BU, respectively. The slave board 206BB has a built-in CPU and is more flexible and sophisticated than the slave boards 206BL and BU (for example, an address is determined in advance for the slave board 206BB, and it is determined whether the received message is addressed to itself. Can be requested to the sub-board 20 when transmitting data). The slave boards 206BL and BU have a predetermined communication procedure with the other party (transmission processing units 209T and 210T, reception processing parts 209R and 210R of the sub board 20), and need not be flexible. . For this reason, the slave substrates 206BL and BU can be configured by a dedicated IC.

  J11 is a model-specific input / output terminal of the sub-board 20. This includes one data and one clock, but the clock is omitted (the same applies to other terminals).

  J21 and J22 are first output terminals, and J31 is a first input terminal. J41 and J42 are second output terminals, and J51 is a second input terminal.

  The harness (model-specific harness) HBB connects the model-specific input / output terminal J11 to the slave substrate 206BB.

  The harness (first harness) HBL connects the first output ends J21 and J22 and the first input end J31 to the slave substrate 206BL.

  The harness (second harness) HBU connects the second output ends J41 and J42 and the second input end J51 to the slave substrate 206BU.

  The transmission processing unit (first transmission processing unit) 209T generates a serial signal to be transmitted from the first output terminals J21 and J21 to the slave substrate 206BL.

  The reception processing unit (first reception processing unit) 209R converts the serial signal received from the slave substrate 206BL at the first input terminal J31 into a parallel signal. The converted parallel signal is subjected to predetermined processing by the sub-board 20.

  The transmission processing unit (second transmission processing unit) 210T generates a serial signal to be transmitted from the second output terminals J41 and J42 to the slave substrate 206BU.

  The reception processing unit (second transmission / reception processing unit) 210R converts the serial signal received from the slave substrate 206BU at the second input terminal J51 into a parallel signal. The converted parallel signal is subjected to predetermined processing by the sub-board 20.

  The transmission / reception processing unit 208 of the slave substrate 206BB performs reception processing and transmission processing according to the address from the I2C transmission / reception processing unit 207. Although only one slave board 206BB is shown in FIG. 5, a plurality of slave boards 206BB can be connected to the same harness HBB (including signal lines branched from now). An address is used to identify the slave substrate 206BB.

  A processing flowchart of the I2C transmission / reception processing unit 207 is shown in FIG. Although the communication process from the sub board 20 to the slave board 206BB and the communication process in the reverse direction are shown separately, the I2C transmission / reception processing unit 207 of the sub board 20 operates as a master in either case.

ST10: When the I2C transmission / reception processing unit 207 transmits a serial signal through the model-specific input / output terminal J11, the I2C transmission / reception processing unit 207 specifies the address of the slave substrate 206BB to which the serial signal is transmitted.

ST11: The I2C transmission / reception processing unit 207 transmits a serial signal to the slave substrate 206BB associated with the address.

ST12: The I2C transmission / reception processing unit 207 notifies the end of transmission after transmission. The slave board 206BB and other slave boards 206BB can know the end of transmission by the end of transmission.

ST20: The I2C transmission / reception processing unit 207 designates the address of the source slave board 206BB in order to receive a serial signal through the model-specific input / output terminal J11 as necessary or in response to a request from the slave board 206BB.

ST21: The I2C transmission / reception processing unit 207 receives a serial signal from the slave substrate 206BB related to the address.

ST22: The I2C transmission / reception processing unit 207 notifies the end of reception after reception. The slave substrate 206BB and other slave substrates 206BB can know the end of reception by the end of reception.

  FIG. 7 is an explanatory diagram of the slave substrates 206BB, 206BL, and 206BU.

  The slave substrates 206BL and 206BB for driving the LEDs include an LED driver IC01. The LED driver IC01 receives serial data from the sub board 20, and blinks a plurality of connected LEDs in a predetermined pattern based on the decoding result of the data. For example, a specific LED is turned on, and the duty ratio is set to a predetermined value to adjust the luminance.

  The slave boards 206BL and 206BU for driving the motor are provided with a motor control circuit IC02. The motor control circuit IC02 receives serial data from the sub-board 20, and excites the connected motor windings in a predetermined pattern based on the decoding result of the data. For example, the winding is sequentially excited to rotate the motor, and the rotation speed is adjusted by changing the excitation frequency. The output of the motor control circuit IC02 is connected to a motor driver DRV for flowing a current necessary for driving the motor through the windings.

  Slave boards 206BL and 206BU including sensors (switches) include a parallel-serial converter IC3 for converting input signals of a plurality of sensors from parallel to serial. The parallel-serial converter IC3 takes in the outputs of a plurality of sensors at predetermined intervals, converts them into serial data, and sends them to the sub-board 20. The serial data is received by the reception processing units 209R and 210R of the sub-board 20, and is subjected to serial-parallel conversion and transferred to the CPU of the sub-board 20.

  According to the embodiment of the invention, the sub-board 20 performs bidirectional communication by designating an address by the I2C transmission / reception processing unit 207 using the model-specific input / output terminal J11 in communication with the model-specific block BB. Can communicate with various model-specific blocks. For example, a plurality of slave boards can be connected by specifying an address, and the number and types of data to be transmitted / received by negotiation by bidirectional communication can be flexibly set.

  The sub board 20 transmits serial data to the slave boards 206BL and 206BU using the first output terminals J21 and J22 and the second output terminals J41 and J42 in communication with the lower door block BL and the upper door block BU. Serial data is received from the slave boards 206BL and 206BU using the first input terminal J31 and the second input terminal J51. The communication is unidirectional, the processing is simple, and the burden on the processing unit is small. In the slave boards 206BL and 206BU, as shown in FIG. 7, a reception process and a transmission process can be performed by a semiconductor element (IC), and it is not necessary to create a program.

  On the other hand, the transmission / reception processing unit 208 is necessary for the slave substrate 206BB, but only the model-specific block BB is necessary, and the number is small.

  By not requiring versatility in communication with the slave boards 206BL and 206BU, the processing load on the sub-board 20 is reduced, the program of the slave boards 206BL and 206BU is unnecessary, and cost reduction can be realized.

  Each slave board has a dedicated model-specific input / output terminal J11, first output terminals J21, J22 and first input terminal J31, second output terminals J41, J42, and second input terminal J51. And each relay board are connected by independent harnesses HBB, HBL, and HBU, so it is only necessary to change the harness HBB when applying to different models. The lower door block BL can be commonly used for different models. Even when the upper door block BU is replaced, the harnesses HBB and HBL can be used continuously. When replacing the upper door block BU, other harnesses are not affected. As described above, the gaming machine according to the embodiment of the invention can easily perform block replacement.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
