Abstract

PROBLEM TO BE SOLVED: To reduce radiation noise caused by serial data signals and clocks used for communication in a game machine.SOLUTION: If a plurality of pieces of data is transmitted, they (5 pieces of pulses) are transmitted in continuation as one group. Therefore, an interval (an idle period; the flat part in the Figure) is generated between a transmission of a certain group and a transmission of a next group. When a plurality of transmission destinations is involved, during a first idle period when data is not transmitted to one side (a first slave board), a change in signals in a first harness is stopped, and during a second idle period when data is not transmitted to the other side (a second slave board), a change in signals in a second harness is stopped. During the second idle period, signals in the first harness are changed to transmit data to the first slave board, and during the first idle period, signals in the second harness are changed to transmit data to the second slave board.SELECTED DRAWING: Figure 7

Description

  The present invention relates to a gaming machine such as a slot machine or a pachinko machine, and more particularly to a machine that reduces noise radiated in the gaming 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.

  Various devices such as a liquid crystal display device, a display lamp for display (electric decoration), and a sound generator (sound device, speaker) are provided in the gaming machine as devices that play a role of enhancing the interest of the player. 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. In the following description, not only the liquid crystal display device, the electrical decoration, and the sound generation device itself but also their control devices may be referred to as “effect devices”.

JP, 2000-126429, A It aims at preventing malfunctioning by noise effectively, ensuring prevention of a cost increase and prevention of fraud. The serial output circuit is provided with a plurality of registers which are storage areas corresponding to output commands for the sound control board, lamp control board, display control board, and prize ball rental board. Control commands from the CPU are set in each register. The control command set in the register is transferred to the corresponding shift register. JP, 2007-275239, A Even if the payout control board is under the influence of noise, it is an object to be able to transmit and receive commands serially between the main control board and the payout control board. Even if the game balls are rubbed against each other and charged, and noise is generated due to electrostatic discharge, the serial IF unit built in the serial-parallel conversion IF chip divides based on the clock signal input from the outside, Since the reception timing and the transmission rate are set, the reception timing and the transmission rate are not affected by noise. Since serial communication is realized by shifting the frequency division instead of conventional parallel communication, the number of signal lines is less than that of parallel communication, and it is less susceptible to noise.

  As described in Patent Documents 1 and 2, serial communication is employed in communication between elements in the gaming machine housing (such as between a main board and a sub board, and between a sub board and its peripheral board). As described in Patent Document 2, serial communication has the advantage that it has fewer signal lines and is less susceptible to noise than parallel communication. In Patent Document 2, serial communication is employed in order to reduce the influence of noise and prevent errors in data transmission.

  There is a sub-board as an element included in the gaming machine. Substrates are substrates for controlling various effect devices such as liquid crystal display devices (liquid crystal panels), effect display lamps (electric decorations), and sound generators (sound devices, speakers). 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.

  The effect device and the sub-board are connected by a harness, and communication is performed through the harness. In the harness, serial communication of Patent Documents 1 and 2 is performed. The harness includes a data line through which a serial signal propagates and a clock line through which a clock for designating timing for acquiring (latching) the serial signal, and the serial communication method is clock synchronous serial communication. Although clock synchronous serial communication requires a clock line, it can be sped up compared to asynchronous communication (start-stop synchronous communication) that does not have a clock line, and is not affected by noise or the like and has high reliability. From this point of view, gaming machines employ clock synchronous serial communication.

  A large number of electrical signals such as clock synchronous serial communication signals are circulated inside the gaming machine, and various electrical noises are emitted from the housing. 2. Description of the Related Art In recent years, in game machine production devices, the amount of communication data transferred has increased in order to perform various productions, and the communication speed has been increased. In particular, a relatively large noise (caused by the clock) that forms a peak at a specific period (for example, a clock period of clock synchronous serial communication) is generated. In addition, production devices may be installed at various locations on the gaming machine casing, and as a result of the increase in the signal line length of the harness connecting these and the sub-board, the harness itself may be a noise source, and radiation noise from the casing In particular, its peak is becoming a problem. If this is left unattended, it may cause a malfunction of the peripheral device, so that it has been required to reduce the peak of this radiation noise.

  Radiation noise is weakly generated in any electronic device, but the intensity of radiation noise tends to increase with a signal that repeatedly turns on and off at regular intervals, such as a clock signal of clock synchronous serial communication.

  Patent Documents 1 and 2 relate to prevention of malfunction due to noise of an electronic device in a gaming machine, and there is no description regarding reduction of radiation noise itself. There is no description about the problem of radiation noise caused by clock synchronous serial communication.

  An object of the present invention is to provide a gaming machine that can reduce radiation noise of a gaming machine, for example, a peak of radiation noise caused by clock synchronous serial communication.

The present invention includes a first slave substrate and a second slave substrate that respectively control devices related to effects, a processing unit that controls the first slave substrate and the second slave substrate, and the processing unit that is the first slave substrate. And a gaming machine comprising a first harness and a second harness respectively connected to the second slave board,

A pause period control unit for instructing the transmitter to transmit the first pause period or the second pause period;
The suspension period control unit may switch between the first suspension period and the second suspension period at a predetermined interval.

  According to the present invention, in data transmission, in a first pause period in which data is not transmitted to the first slave board, a change in the signal of the first harness is stopped and data is not sent to the second slave board. In the period, the change of the signal of the second harness is stopped, and in the second pause period, the signal of the first harness is changed and data is transmitted to the first slave substrate. In the first pause period, Since the signal of the second harness is changed and data is transmitted to the second slave substrate, the transmission of data is temporally dispersed to reduce noise synchronization and suppress radiation noise.

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 includes means for generating random numbers used for production.

  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. Further, the prescribed number of throws may be set according to the game state, and the prescribed number of throws is set to 3 in the normal state, the bonus establishment state, and 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 the big bonus is won by internal lottery, the big bonus 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 (the frame detected by the reel index) of the spinning cylinder based on the reference position signal detected by the index sensor 159 every time the rotating cylinder makes one rotation. 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).

  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 medals (the detection order of the sensors S1 and S2 is reversed), the medal retention (the detection time of the sensors S1 and S2 is 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 202B, 202U and 202L, speaker SP, bass speaker SPL, solenoid SN, motors MU and ML, sensors SENU and SENL, and switch SW. The LEDs 202B, 202L, and 202U incorporate a latch that acquires and holds data and an LED that is an electrical 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.

  Although not shown, the model-specific block BB and the lower door block BL have a video controller (VDC) for controlling the liquid crystal panel LCD2, a speaker SP, and a sound for generating sound by driving the speaker SP. A drive circuit (not shown) for driving the controller, solenoid SN, motors MU and ML is incorporated.

  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 a solenoid SN, a speaker SP, and an LED 202B, and the upper door block BU includes a liquid crystal panel LCD1, an LED 203U, a motor MU, and a sensor SENU that detects the operation of the movable body. The lower door block BL includes a liquid crystal panel LCD2, a speaker SP, an LED 202L, a motor ML, a sensor SENL that detects the operation of the movable body by the motor ML, 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 a command 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, suggestions for obtaining a ball are displayed on a display device such as a liquid crystal display device in order to provide convenience (assist) for the player's operation. The suggestion is not always issued, but in specific cases. Note that the present invention is not limited to a mode in which the sub board displays AT (notifies) based on a command from the main board. For example, the main board may display (notify) the AT by a display (notification means) under the control of the main board. The following description also applies to such a form.

  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, and notifies the player of a prize or the like, or plays a specific small role for a certain game during a certain game at a so-called assist time (AT) to the user with some action. It is for teaching. (Assist Time (AT): Even if a specific small role is won, the player will not be paid out unless the symbol combination corresponding to this small role is aligned on the winning judgment line. , After the big bonus is over (or at the time of winning) or at any other opportunity, the assist time will be drawn in order to align the symbol combination corresponding to a specific small role on the winning judgment line for a certain game (That tells the player about the stop operation with some action)

  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 symbol combinations 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 the symbol combinations arranged on the winning determination line 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).

  The above-described gaming machine is separated into a plurality of blocks such as an upper door block BU and a lower door block BL, and can be independently incorporated or removed (separated housing). Manufacturing, shipment, and installation may be performed in a state where some blocks, for example, the lower door block BL are not incorporated.

  FIG. 5 is a block diagram showing connections of sub-boards, slave boards (relay boards), rendering devices such as LEDs, solenoids, motors, and sensors (photosensors, switches, etc.) according to the embodiment of the invention. FIG. 5 shows the connection system related to the production device and the slave board in the block diagram of FIG. At least the harnesses HBU and HBL connecting the sub board 20 and the slave boards 206BU and 206BL specify the data line through which the digital signal propagates and the timing for acquiring (latching) the digital signal, as shown in the lower left of FIG. And a clock line through which a clock signal to be transmitted propagates, and a communication system between them is clock synchronous serial communication. 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 the CPU 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 present invention, I2C (Inter-Integrated Circuit) or clock synchronization is used as a control communication method from the sub-board 20 to a slave board (relay board) that controls effect devices such as accessories and electrical decorations. Uses serial communication. As the number of controlled objects / devices increases, the sub board connects to the slave board via serial communication, and each slave board performs serial-parallel conversion (serial-parallel conversion). Each slave board is connected to a device such as an accessory or illumination.

  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. As a communication method between the sub-board 20 and the upper door block BU, synchronous serial communication is used. 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 method between the sub-board 20 and the lower door block BL uses synchronous serial communication. 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 line and one clock line (same for 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 HBL connects the first output terminals J21 and J22 and the first input terminal J31 to the slave substrate 206BL.

  The 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 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 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 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 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.

  FIG. 6 is an explanatory diagram of the slave substrates 206BB, 206BL, and 206BU.

  The slave boards 206BL, 206BU, and 206BB that drive the LEDs include an LED driver IC01. The LED driver IC01 receives a serial signal and a clock from the sub-board 20, acquires data from the serial signal based on the clock, and determines a plurality of LEDs 202L, 202U, and 202B that are connected based on a decoding result of the data. Flashes in a pattern. 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 the serial signal and clock from the sub-board 20, acquires data from the serial signal based on the clock, 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 receives a clock from the sub-board 20. The parallel-serial converter IC3 takes in the outputs of a plurality of sensors at predetermined intervals, converts the sensor data into serial signals based on the clock, 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.

  In the gaming machine according to the embodiment of the invention, the communication path is increased due to the addition of the liquid crystal panel LCD2 to the lower door block and the radiation noise is increased as compared with the conventional gaming machine, and particularly the peak noise is increased. Since radiated noise can affect other devices, it has been required to reduce it.

  In the embodiment of the invention, the peak of radiation noise is suppressed by the following means.

  For the two communication paths (harnesses HBU and HBL) extending from the sub-board 20, for example, transmission timings of control signals (commands) related to electrical decoration control (LED lighting) are set to be different from each other (electrical decoration control and Other than this, or a combination of controls other than the illumination control may be used). This prevents noise synchronization and reduces emission noise.

  That is, the change of the signal (serial signal and / or clock) of the harness HBL is stopped in the first pause period during which no data is transmitted to the slave board 206BL, and the harness HBU is sent during the second pause period during which no data is transmitted to the slave board 206BU. The change of the signal (serial signal and / or clock) is stopped. On the other hand, in the second pause period, the signal of the harness HBL is changed to transmit data to the slave board 206BL, and in the first pause period, the signal of the harness HBU is changed to send data to the slave board 206BU.

  The above operation will be described with reference to the timing chart of FIG. 7 and FIG. FIG. 7A shows data transmission timing according to the embodiment of the present invention (a serial signal and a clock are schematically represented together). FIG. 7B is a comparative example.

  As shown in FIG. 7A, in the data transmission in the embodiment of the invention, there is a pause period during which no data is transmitted, and therefore there is an interval between the transmission of the serial signal. For example, when sending lighting data of a plurality of LEDs, lighting data for each LED is generated and transmitted, so the number of data corresponds to the number of LEDs. These data (five pulses in FIG. 7A) constitute a group, and the sub-board 20 transmits them all together (transmits in units of groups). As a result of transmission in units of groups, an interval (pause period) occurs between transmission of a certain group and transmission of the next group (flat portion in FIG. 7A). Regarding the visual effect of the LED or the like, if the change interval is within a predetermined time (for example, several tens of ms), the player does not feel discomfort such as flicker even when there is a pause period. Similarly, there is an interval in data transmission to the motor driver. Thus, since the sub-board 20 transmits data at a predetermined interval, it does not always transmit data, and there is a pause period for data transmission. This rest period exists in each of the harnesses HBU and HBL and can be set independently.

  Although it is possible to prevent the serial signal from changing during the idle period, predetermined data (dummy data) may be transmitted for synchronization, and generally, the clock is not stopped during the idle period.

  In the embodiment of the invention, the change of the serial signal is stopped in the idle period. Further, the change of the clock may be stopped together with this. For example, the clocks generated by the transmission processing units 209T and 210T in FIG. 5 and output from the output terminals J21, J22, J41, and J42 are disconnected by hardware such as a switch provided in the middle of the path, or the transmission processing units 209T, The 210T clock generation is stopped by software (the clock output function is stopped). According to the embodiment of the present invention, data is transmitted to the slave substrate 206BU in a period in which data is not transmitted to the slave substrate 206BL (first suspension period), and data is not transmitted to the slave substrate 206BU (second Data is transmitted to the slave substrate 206BL in the pause period). Thus, radiation noise can be suppressed by preventing the data transmission periods from overlapping. That is, the radiation noise in the first pause period is only due to the signal of the harness HBU, and the radiation noise in the second pause period is only due to the signal of the harness HBL, and they do not overlap. Conceptually, the radiation noise peak occurs in transmission to the slave substrate 206BL and transmission to the slave substrate 206BU as shown in FIG. In the example of the figure, Peak2 noise occurs every time data is transmitted. Peak2 is caused by either transmission to the slave substrate 206BL or slave substrate 206BU. The peak 2 interval corresponds to the transmission interval (corresponding to the pause interval).

  On the other hand, when data is transmitted simultaneously as shown in FIG. 7B, the radiation noise of the signals of the harnesses HBL and HBU is superimposed and increased. In the example of FIG. 8B, Peak 1 noise occurs every time data is transmitted. Peak1 is larger than Peak2. Peak1 is caused by both the transmission to the slave substrate 206BL and the slave substrate 206BU. The interval of Peak 2 corresponds to the transmission interval, which is twice that of FIG.

  Therefore, according to the embodiment of the invention, the transmission of data can be distributed to reduce the synchronization of noise, and the generation of radiation noise can be suppressed.

  A specific example of data transmission switching control will be described.

  FIG. 9 shows an internal block diagram of the transmission processing unit 209T. The illustration of the transmission processing unit 210T is omitted (the configuration is the same as 209T).

  The data registers 2101a and 2101b, the transmission data registers 2102a and 2102b, and the transmission shift registers 2103a and 2103b may be configured by software (program).

  Reference numeral 2111 denotes an oscillator that generates a reference signal serving as a clock reference.

  Reference numeral 2112 denotes a clock generator that generates a clock for clock synchronous serial communication based on a reference signal. The transmission shift registers 2103 a and 2103 b transmit data based on the output of the clock generator 2112. The clock of the clock generator 2112 is supplied to the slave boards 206BU and 206BL. The slave boards 206BU and 206BL on the receiving side receive serial signals based on the clock of the clock generator 2112.

  2120 instructs the data register (transmission unit) 2101a to start transmission (this corresponds to the start of the second pause period), and starts transmission to the data register (transmission unit) 2101b (this corresponds to the start of the first pause period). ) Is a pause period control unit. Note that the transmission data registers 2102a and 2102b may be the target for instructing the pause period. The pause period control unit 2120 starts the first pause period based on the end of data transmission to the slave board 206BL, and starts the second pause period based on the end of data transmission to the slave board 206BU. In the example of FIG. 9, a transmission end signal is received from the transmission data registers 2102a and 2102b, and the operation is performed based on this signal. For example, if the transmission data registers 2102a and 2102b are FIFO (first-in, last-out) buffers, all the data held inside is output and a signal (empty signal) indicating this is output when it becomes empty. The signal is a transmission end signal. The idle period control unit 2120 is, for example, a flip-flop. If the state is changed by a signal from the transmission data register 2102a and the state is changed by a signal from the transmission data register 2102b, the state corresponds to the idle period. . A transmission start signal is output at the start of one pause period, and the other data register starts output.

When the data transmission of LED202L-1 to LED202L-N is completed, that is, when the data transmission of LED202L-N is started, the first suspension period starts, and the suspension period control unit 2120 commands the data register 2101b to start transmission (reference P). When the data transmission of LED202U-1 to LED202U-M is completed, that is, when the data transmission of LED202U-M is started, the second suspension period is entered, and the suspension period control unit 2120 commands the data register 2101a to start transmission (symbol Q). The above processing is repeated.
