Description

  The present invention relates to a gaming machine such as a slot machine installed and used in a game hall such as a pachinko parlor.

  In this specification, description will be made using medals as game media, but the game media includes other media such as coins. “Medal (game medium) insertion” includes betting a stored (credit) medal with a bet button or the like in addition to actually inserting a medal into the medal insertion slot.

    Slot machines that are installed and used in amusement halls such as pachinko parlors are called pachislot machines, and medals that are used as gaming media are given a certain value, and medals earned by playing games are various prizes. Can be replaced. For this reason, it is common for a player to try to play a game by simply selecting a table that easily obtains the right to shift to the bonus game mode only for the purpose of acquiring a large number of medals. The bonus game mode includes, for example, a big bonus (hereinafter referred to as BB) mode and a regular bonus (RB) mode. In particular, the BB mode is shifted to the RB mode a predetermined number of times and before being switched to the RB mode, a certain amount of Since the mode is shifted to the RB introduction mode in which the winning probability of the small role where the medal is paid out is increased, a large amount of medals can be obtained in a short period of time.

  In the slot machine, it is possible to select and set one of a plurality (for example, six types) of lottery tables having different winning lottery probabilities. Depending on the setting of the lottery table, the above BB mode and RB can be selected. Most models change the probability of transition to mode. The lottery table is set, for example, by opening the front door of the slot machine and turning on the power, inserting a dedicated setting key into the keyhole to enter the lottery table setting mode, and operating the setting change button. When the setting key is pulled out from the key hole, the game can be executed. When the lottery table used in the game is set, a signal is transmitted to the circuit board for processing the game, and the game is executed based on the set lottery table.

The lottery table is often set after the game hall is closed on a daily basis. For example, a lottery table having a lottery table with a high probability of winning per lot has a low lottery probability per day. A slot machine with a high probability of winning per player, such as a lottery table with a low lottery probability, or a lottery table with a low probability of winning per lot. Ingenuity has been devised so that it cannot be predicted. Since the fact that the lottery table has been changed cannot be detected from the appearance of the slot machine, the game is played fairly for any player.

Behind the lottery table code display window 34, the type of the lottery table selected by operating the setting change button 31c through the lottery table code display window 34 and the game by operating the start lever 21 are used. A lottery table code display device 35 (see FIG. 3) for displaying the type of the set lottery table is provided. When a lottery table is selected by pressing the setting change button 31c during the lottery table setting mode, a code indicating the type of the selected lottery table is flashed and selected through the lottery table code display window 34. When the lottery table is set to be used in the game by operating the start lever 21, the blinking display is stopped and the code indicating the set lottery table type is statically displayed. In the lottery table confirmation mode, a code indicating the type of the lottery table set to be used in the game by the lottery table code display device 35 is statically displayed through the lottery table code display window 34.

  As shown in FIG. 3, the operation of the slot machine 2 is basically controlled by a control unit 42 including a CPU (notification control means) 40 and a memory 41. In addition to the CPU 40 and the memory 41, the control unit 42 is provided with an electronic lottery unit 43, a winning combination determining unit 44, and a timer (timer) 45.

  Sensors are provided in the single bet button 17 and the MAX bet button 18, and a signal is input to the CPU 40 when each button is pressed. The CPU 40 determines the number of 1-3 medals inserted prior to the start of the game based on a detection signal from the medal sensor 46 or an input signal from either the 1-bet button 17 or the MAX bet button 18. And determine the number of activated winning lines. Further, the bet number of medals inserted into the medal insertion slot 25 when the game is started is counted by a credit medal counter (not shown) provided in the CPU 40, and the one bet button 17 or the MAX bet button 18 is operated. Each time a medal insertion operation is performed, the bet number of medals is successively subtracted from the credit number.

  A sensor is provided inside the settlement button 19, and a signal is input to the CPU 40 when the settlement button 19 is pressed. When the settlement button 19 is pressed while medals are stored in the credit medal counter, all the medals stored in the credit medal counter are subtracted, and medals for the number of medals stored in the credit medal counter. Are all paid out to the medal tray 33 by the hopper device 30b.

  The start switch sensor 47 is turned on when the start lever 21 is operated. When the start lever 21 is operated during the game mode, a game start signal is input to the CPU 40. When the start lever 21 is operated during the lottery table setting mode, the start switch sensor 47 is set. A signal is input to the CPU 40. In response to the game start signal, the CPU 40 rotates the first to third reels 11a to 11c based on the game execution program stored in the ROM area of the memory 41 and starts the game process. The RAM area of the memory 41 is a working area, and is used for temporary storage and rewriting of flags and data used for setting the mode of the slot machine 2 and flags and data used for each game. It is done.

  The reel drive control unit 48 controls the drive and stop of each reel. Each of the first to third reels 11a to 11c is fixed to a drive shaft of an individual stepping motor 49a to 49c, and each reel is controlled by controlling the driving of each stepping motor 49a to 49c.

  Since the stepping motors 49a to 49c rotate at a rotation angle corresponding to the number of supplied drive pulses, the CPU 40 controls the rotation angle of the first to third reels 11a to 11c by controlling the number of supplied drive pulses. The stop position of the reel can be determined by stopping the supply of the drive pulse. Each reel is integrally formed with reflection signal portions 50a to 50c at the reference position, and the photosensors 51a to 51c photoelectrically detect the passage of each reflection signal portion for each rotation. Detection signals from the photosensors 51a to 51c are input to the CPU 40 as a reset signal for each reel.

  The CPU 40 is provided with a pulse counter for each of the stepping motors 49a to 49c, and counts the number of drive pulses supplied to each of the stepping motors 49a to 49c. When the reset signal is input from the photosensors 51a to 51c, the count value of the corresponding pulse counter is cleared. Therefore, the number of drive pulses corresponding to the rotation angle within one rotation of each reel is stored in each pulse counter while being sequentially updated.

  A symbol table is stored in the ROM area of the memory 41. In the symbol table, the number of drive pulses corresponding to the rotation angle from the reference position of each reel and the symbol representing each symbol arranged on the reel at a constant pitch are stored. A code is associated. Therefore, by monitoring the count value of the pulse counter for each reel, for example, it is possible to identify which symbol has moved on the central pay line, and to what extent the reel is further rotated. It can be predicted whether the symbol of will move on the winning line.

  Sensors are provided inside the first to third stop buttons 22 to 24, and a stop signal for each reel is input to the CPU 40 when the first to third stop buttons 22 to 24 are operated. The start lever 21 is operated to start the rotation of all reels. When these rotations reach a steady speed, the operation of the first to third stop buttons 22 to 24 is validated. Thereafter, by operating these, stop control of the corresponding first to third reels 11a to 11c is started.

  The CPU 40 operates the electronic lottery unit 43 in response to the game start signal. The electronic lottery unit 43 includes a random number generator and a random number sampling circuit, and determines one random value by lottery every time a game is started. The random number value determined here is input to the winning combination determination unit 44. The winning combination determination unit 44 determines what type of winning combination is awarded in the currently executed game according to the input random value.

  The winning combination determining unit 44 is provided with a plurality of (for example, six types) lottery tables having different winning lottery probabilities. In the lottery table, the random value sampled in the game in the normal mode is BB that gives the right to shift to the BB mode, the RB that gives the right to shift to the RB mode, and the small role winning pattern that only pays out a predetermined number of medals. Is used to determine which symbol belongs to, such as a small role corresponding to, a replay that gives the right to play the next game with the same number of bets without inserting medals, or a winning that does not cause any wins, that is, a winning determination. There are a plurality of types of small role winning symbols, and a payout medal is assigned to each. The type and symbol of the winning are determined depending on which winning symbol the sampled random number value belongs to. In this way, the winning combination determining unit 44 determines whether or not to win using any one of the input random number value and a plurality of types of lottery tables. When the winning combination is determined by the winning combination determination unit 44, a winning combination determination signal indicating the type of the determined winning combination or winning combination is input to the CPU 40.

  The hopper device 30b pays out a prescribed number of payout medals to the medal tray 33 according to the type of winning combination. A payout table in which the number of payout medals is determined for each type of winning combination is stored in the ROM 41, and the CPU 40 reads this to drive the hopper device 30b.

  A key sensor 52 and a mode selection switch 53 are provided inside the key hole 31b. The key sensor (identification means) 52 is turned on when a predetermined key is inserted into the key hole 31b, and a first detection signal indicating that the predetermined key has been inserted into the key hole 31b is input to the CPU 40, and the key is received from the key hole 31b. When the key is pulled out, it is turned off, and a second detection signal indicating that the key has been pulled out from the keyhole 31b is input to the CPU 40. Thus, the key sensor 52 functions as an identification unit that identifies whether or not a key has been inserted into the keyhole 31b.

  In response to the first detection signal from the key sensor 52, the CPU 40 inputs a notification start signal to the error code display device 15, the lamp control device 55, and the voice control device 56. Further, the CPU 40 inputs a timing start signal to the timer 45 in response to the second detection signal. The timer 45 starts timing in response to the timing start signal. As described above, the timer 45 functions as a time measuring unit that starts time counting when it is identified that the key has been pulled out from the keyhole 31b.

  The CPU 40 compares the preset time (for example, 30 seconds) stored in the ROM area of the memory 41 with the time measured by the timer 45. The CPU 40 notifies the error code display device 15, the lamp control device 55, and the voice control device 56 that the time measured by the timer 45 has reached a preset time stored in the memory 41. Input an end signal.

  Note that the preset time stored in the memory 41 is sufficient to notify the surrounding players and game shop employees that the error code display device 15, the lamp control device 55, and the voice control device 56 will be described later. It suffices for the time to be recognized by the user and can be changed as appropriate.

  In response to the notification signal, the error code display device 15 performs a setting operation such as selecting and setting a code indicating that a key has been inserted into the keyhole 31b through the error display window 14, that is, a lottery table (setting). A code indicating that the operation is in progress. Further, the error code display device 15 responds to the notification end signal and ends the display of the code. The “setting operation” means that a lottery table setting mode is selected by inserting a key into the keyhole 31b and performing a predetermined operation, and then pressing the setting change button 31c to select a lottery table and operating the start lever 21. Thus, the selected lottery table is set to be used in the game, and a series of operations until the key is pulled out from the keyhole 31b is shown.

  The lamp control device 55 reads a lighting pattern program indicating a lighting pattern to be lit by the lamp 27 at the time of performance during a game or when an error is notified, thereby reading a driver (not shown). The lighting control of the lamp 27 is performed via In response to the notification signal, the lamp control device 55 performs a setting operation such as selecting and setting a lighting pattern program indicating that a key has been inserted into the keyhole 31b, that is, a lottery table (the setting operation is being performed). And the lighting of the lamp 27 by the lighting pattern based on the lighting pattern program, that is, the notification lighting pattern is started. In addition, the lamp control device 55 ends the lighting of the lamp 27 by the notification lighting pattern in response to the notification end signal.

  Note that a special lighting pattern that is not used during the game, that is, a lighting pattern that is differentiated from other lighting patterns, is used as the notification lighting pattern, indicating that the setting operation is being performed, and that the game shop employees and surrounding games To make it clear to the person.

  The sound control device 56 performs output control of the sound output from the speaker 28 by reading out a sound program corresponding to the situation from a sound memory (not shown) at the time of performance during a game or reporting an error. Specifically, an audio signal based on a sound program is input to an electronic volume (not shown) via a buffer (not shown). The electronic volume is composed of a variable resistor, and the volume of the sound output from the speaker 28 is adjusted in the electronic volume. After adjusting the volume with the electronic volume, the audio signal is input to an amplifier (not shown). The amplifier amplifies the audio signal, and the amplified audio signal is output from the speaker 28 via a driver (not shown).

  In response to the notification signal, the voice control device 56 performs a setting operation such as selecting and setting a sound program indicating that a key is inserted from the sound memory into the keyhole 31b, that is, a lottery table (setting operation). A sound program indicating that the sound program is in the middle is read out, and a sound based on the sound program, that is, a notification sound is generated from the speaker 28. In addition, the voice control device 56 stops the notification voice in response to the notification end signal.

  Note that the notification voice is, for example, a voice expressing that a setting operation such as “the key has been inserted into the keyhole” or “the setting operation is in progress” is being performed. In addition, the volume is set so as to be larger than the volume at the time of directing the game, and the player and the person in the vicinity of the player (for example, the person in the seat next to the player or the game The person who passes behind the person) is set so that the difference can be clearly distinguished. As a result, the notification indicating that the setting operation is being performed can be highlighted.

  In this way, the lamp 27, the speaker 28, the error code display device 15, the lamp control device 55, and the voice control device 56 function as notification means for notifying that the setting operation is being performed. In addition, the CPU 40 starts notification that the setting operation is being performed when the key is identified as being inserted into the keyhole 31b, and the timer 45 measures the predetermined time. It functions as notification control means for terminating notification.

  The mode selection switch 53 is turned on when the main power is turned on after a predetermined key is inserted into the keyhole 31 b and rotated from the off position to the on position, and an on signal is input to the CPU 40. Thereafter, when the key is rotated from the on position to the off position, the mode selection switch 52 is turned off and an off signal is input to the CPU 40.

  A sensor is provided inside the setting change button 31c, and a selection signal is input to the CPU 40 in response to the pressing operation of the setting change button 31c.

  When the ON signal from the mode selection switch 53 is input to the CPU 40, the lottery table setting mode is set. In response to the selection signal from the setting change button 31c, the CPU 40 outputs a selection execution signal corresponding to the selection signal to the winning combination determining unit 44. To enter. The winning combination determining unit 44 selects a lottery table corresponding to the selection execution signal from the plurality of lottery tables in response to the selection execution signal.

  In the lottery table setting mode, after the lottery table is selected as described above, the CPU 40 inputs a setting execution signal to the winning combination determining unit 44 in response to the setting signal from the start switch sensor 47. In response to the setting execution signal, the winning combination determination unit 44 sets the lottery table selected by the selection execution signal to be used in the game. After the lottery table is set in this manner, when the off signal from the mode selection switch 53 is input to the CPU 40, the game mode is shifted from the lottery table setting mode.

  In the lottery table setting mode, the CPU 40 ignores the off signal before the setting signal from the start switch sensor 46 is input, and responds only to the off signal after the setting signal is input. That is, the lottery table setting mode cannot be shifted to the game mode unless the lottery table is set by operating the start lever 21.

  When the mode switch 53 is turned on after the power switch 31 a of the slot machine 2 is turned on, a lottery table confirmation signal is input to the CPU 40. When the lottery table confirmation signal is input to the CPU 40, the lottery table confirmation mode is set, and a code indicating the type of the lottery table set to be used in the game is displayed by the lottery table code display device 35 through the lottery table code display window 34. Is done. When the mode selection switch 53 is turned off, a lottery table confirmation cancellation signal is input to the CPU 40. When the lottery table confirmation release signal is input to the CPU 40, the display by the lottery table code display device 35 is terminated, and the game mode is entered.

  Next, the operation of the slot machine 2 configured as described above will be described with reference to the flowchart of FIG. When a predetermined key is inserted into the key hole 31b, the key sensor 52 detects this and inputs a first detection signal to the CPU 40. The CPU 40 activates the error code display device 15, the lamp control device 55, and the sound control device 56 in response to the first detection signal, and notifies them that the setting operation is being performed.

  When a predetermined key is inserted into the key hole 31b and the main power is turned on after the key is rotated from the on position to the off position, the lottery table setting mode is entered, and the lottery table can be selected and set. When the lottery table is set by the setting change button 31c and the start lever 21, and the key is rotated from the off position to the on position and then the key is pulled out from the key hole 31b, the key sensor 52 detects this, and the second detection signal is generated. Input to the CPU 40. The CPU 40 inputs a timing start signal to the timer 45 in response to the second detection signal. The timer 45 starts timing in response to the timing start signal. When this timing reaches a predetermined time, the CPU 40 inputs a notification end signal to the error code display device 15, the lamp control device 55, and the sound control device 56. In response to the notification end signal, the error code display device 15, the lamp control device 55, and the voice control device 56 end the notification indicating that the setting operation is being performed.

  As described above, when the key is identified as being inserted into the keyhole 31b, the notification indicating that the setting operation is in progress is started, and the notification is performed for a predetermined time after the key is pulled out from the keyhole 31b. Since the operation is continued, it is possible to surely notify the game shop employee and surrounding players that the lottery table setting operation is being performed. Even if an unauthorized setting operation is performed quickly, the notification continues even after the setting operation is completed, so that it is difficult to perform an illegal act. Thereby, an illegal setting operation can be prevented.

  In the above embodiment, notification is performed using the error code display device 15, the lamp control device 55, and the voice control device 56, but notification is performed using a hall computer that exchanges game information with the slot machine 2. May be performed.
