As shown in FIG. 5B, when the main body 33a of the setting change key 33 is inserted into the key insertion hole 31c of the key cylinder 31, a key lock mechanism (table selection permission means) (not shown) provided in the key cylinder 31 is provided. ) Is released, and the setting change key 33 is rotated, the rotation unit 31b rotates to a position where it can be turned on. As will be described in detail later, a plurality of winning tables in the slot machine 2 are provided, and a setting value is assigned to each of them. In the present embodiment, the setting value is “1” to “6”, and the setting value is “1 → 2 →... → 6 → 1 → 2 → whenever the setting change button 32 is operated once when the setting is changed. "..." is set to be changed in this order.

  As shown in FIG. 6, the operation of the slot machine 2 is basically controlled by the main board 24. In addition to the CPU 24a and ROM 24b, the main board 24 is provided with an electronic lottery unit 24c and a winning combination determining unit 24d. The ROM 24b stores, for example, a control program such as a game execution program executed by the CPU 24a, control data necessary for executing these programs, and the like. The ROM 24b stores authentication data for collation with the data read by the data reader 34. This authentication data is data that matches the identification data stored in the IC chip 36.

  The ROM 24b stores first to sixth winning tables 41 to 46 and a setting change program 47. The first to sixth winning tables 41 to 46 are provided such that the winning probabilities for the loser and the plurality of types of winning combinations are different from each other, and the selected winning table has a medal payout probability (payout rate) in the game. Will be different. In this embodiment, the winning table with the lowest payout rate is the first winning table 41, the winning table with the highest payout rate is the sixth winning table 46, and when the set value is “1”, the first winning table is given. When the table 41 is selected and the set value is “6”, the sixth winning table 46 is selected. The first to sixth winning tables 41 to 46 may be provided so that at least any one of a plurality of types of winning combinations has different winning probabilities, and the winning combinations provided to have different winning probabilities. The number is appropriately changed. Thereby, by the operation of the key cylinder 31 and the setting change button 32 of the setting board 25, at least any one of a plurality of types of winning combinations is changed. Further, the first to sixth winning tables 41 to 46 and the setting change program 47 may be stored in the winning combination determining unit 24d.

  In the present embodiment, when the administrator of the game hall where the slot machine 2 is installed changes the setting value of the slot machine 2, the main body 33a of the setting change key 33 is first inserted into the key insertion hole 31c of the key cylinder 31. The key lock mechanism (table selection permission means) provided inside the key cylinder 31 is unlocked, and the rotating portion 31b is turned to the ON position (see FIG. 5B). When the main power of the slot machine 2 is turned on by operating the switch 30, the setting change program 47 is activated and the setting value is displayed on the credit amount display unit 17. In this state, the setting change button 32 is operated to set the setting value. The value has been changed. Thereby, the administrator of the game hall can change the set value while confirming the set value. For example, when the setting value before change is “3” and the setting value is changed to “6”, the setting change button 32 is operated three times. As a result, the set value is changed in order of “3 → 4 → 5 → 6”, and the set value becomes “6” after three operations. Then, when the start lever 18 having a confirmation switch function for confirming the set value is operated, the set value “6” is confirmed, and the rotating portion 31b is rotated to the off position (see FIG. 3) and the setting change key 33 is pressed. When the card is removed from the insertion hole 31c, the set value displayed on the credit number display unit 17 is not displayed.

  During normal times (when the main power of the slot machine 2 is on and the setting is not changed, for example, when the game hall is in operation), the dummy key 35 is inserted into the key insertion hole 31c, and the set value of the slot machine 2 When changing the above, it is necessary to remove the dummy key 35 from the key insertion hole 31c. When the main power supply of the slot machine 2 is turned off by operating the power switch 30, the main body portion 37a of the solenoid 37 is inserted from the insertion position (see FIG. 4B) to the insertion release position according to a command from the CPU 24a. (See FIG. 4A). Thereby, the dummy key 35 can be extracted from the key insertion hole 31c. When the main power supply of the slot machine 2 is turned on after removing the dummy key 35 from the key insertion hole 31c, the data read by the data reader 34 (in this case, no data) and the authentication data stored in the ROM 24b (see FIG. 6) Will not match. The CPU 24a generates an alarm sound from the speaker 22 when the data read by the data reader 34 and the authentication data stored in the ROM 24b (see FIG. 6) do not match. In order to stop the generation of the alarm sound from the speaker 22, a stop switch (not shown) is operated. The CPU 24a stops generating the alarm sound from the speaker 22 in response to the operation of the stop switch. This stop switch can be operated only by, for example, a hall computer that manages and manages the entire amusement hall, and cannot be operated by a person who performs an illegal act. When the CPU 24a generates an alarm sound from the speaker 22 in response to the fact that the data read by the data reader 34 and the authentication data stored in the ROM 24b do not match, the CPU 24a stores the data read by the data reader 34 and the ROM 24b thereafter. Even when a match with the authentication data is determined, the alarm sound from the speaker 22 continues to be generated. That is, the alarm sound from the speaker 22 cannot be stopped unless the stop switch is operated. It should be noted that the stop switch only needs to be prevented from being operated easily by a person who performs an illegal act, and may be provided inside the storage box 4 that cannot be operated unless the front door 5 is opened. Of course, the user may not be able to perform the operation without inputting the password.

  The medal sensor 51 detects an appropriate medal inserted from the medal slot 16 and inputs it to the CPU 24a. A selector is incorporated in the back of the medal insertion slot 16 and an inappropriate medal is discharged to the medal tray 20. In addition, when a selector inserts a medal at an inappropriate timing, for example, a medal inserted in the middle of a game or while various operation buttons are pressed without passing through the medal sensor 51. The medal tray 20 is discharged.

  Since the number of medals inserted prior to the start of the game is limited to 1 to 3, the medal sensor 51 also detects medals inserted after the fourth one when the credit function is not used. Without being discharged to the medal tray 20. The credit function is turned on / off every time the payout button is pushed. When the credit function is on, medals inserted after the fourth sheet are also detected by the medal sensor 51 and credited into the slot machine 2 up to 50 sheets.

  The number of credited medals is digitally displayed on the credit number display unit 17. When the credit function is used, a medal insertion operation is performed by the operation of the 1 bet button or the MAX bet button described above, and the bet number is sequentially subtracted from the credit number. Further, when a game is performed and a winning with a medal payout is obtained, a payout medal is also credited, and when the payout button is operated, the credited medal is paid out to the tray 20.

  The CPU 24a counts the number of 1 to 3 medals inserted prior to the start of the game based on the detection signal from the medal sensor 51, and determines the number to activate the winning effective line. The number of credits is counted by another credit medal counter (not shown).

  The start signal sensor 52 inputs a game start signal indicating that the start lever 18 is operated to the CPU 24a when the start lever 18 is operated after 1 to 3 medals are inserted. In response to the game start signal, the CPU 24a rotates the first to third reels 11 to 13 and starts the game process based on the program for executing the game stored in the ROM 24b.

  The drive and stop control of the first to third reels 11 to 13 and the sub reel 14 are performed by the CPU 24 a and the reel drive controller 53. Each reel is attached to a drive shaft of an individual stepping motor 55a to 55d, and each reel is controlled by controlling the driving of each stepping motor 55a to 55d. The RAM area of the ROM 24b is used for temporary storage or rewriting of flags and data used for each game.

  The stepping motors 55a to 55d rotate at a rotation angle corresponding to the number of drive pulses supplied from the CPU 24a. Therefore, the rotation angle of the first to third reels 11 to 13 and the sub reel 14 can be controlled by controlling the number of drive pulses supplied from the CPU 24a, and the reel stop position can be stopped by stopping the supply of drive pulses. Can be decided. Each reel is integrally formed with reflection signal portions 56a to 56d at its reference position, and the photosensors 57a to 57d photoelectrically detect the passage of each reflection signal portion for each rotation. Detection signals from the photosensors 57a to 57d are input to the CPU 24a as a reset signal indicating the reference position of the reel.

  The CPU 24a is provided with a pulse counter that counts the number of drive pulses supplied to the stepping motors 55a to 55d. The CPU 24a responds when a reset signal is input from the photosensors 57a to 57d. Clear the count value of the pulse counter. 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.

  In the ROM area of the ROM 24b, a symbol table is stored in which the number of drive pulses corresponding to the rotation angle from the reference position of each reel is associated with symbol codes representing symbols arranged on the reel at a constant pitch. Has been. The CPU 24a monitors the count value of the pulse counter for each reel while referring to this symbol table, thereby identifying which symbol has moved on, for example, the middle prize winning line, and to what extent If the reel is rotated, it can be predicted whether the target symbol will move on the winning line.

  When the stop buttons 19a to 19c are operated, the stop button sensors 58a to 58c input a stop signal indicating that the stop buttons 19a to 19c are operated to the CPU 24a. When the start lever 18 is operated to start rotation of the first to third reels 11 to 13 and these rotations reach a steady speed, the CPU 24a validates the operation of the stop buttons 19a to 19c. Thereafter, when the stop buttons 19a to 19c are operated, stop control of the first to third reels 11 to 13 corresponding to the stop buttons 19a to 19c is started.

  The CPU 24a operates the electronic lottery unit 24c in response to the game start signal. The electronic lottery unit 24c includes a random number generator and a random value sampling circuit, and draws one random value every time a game is started. The random value selected by lottery is input to the winning combination determining unit 24d. In the winning combination determination unit 24d, it is determined what type of winning combination is awarded in the currently executed game according to the input value.

  The above-mentioned setting of the first to sixth winning tables 41 to 46 in the ROM 24b determines whether the random value lottery selected by the electronic lottery unit 24c is lost or a plurality of types of winning combinations. The decision is made with reference to the winning table selected by value. In addition to the first to sixth winning tables 41 to 46 for the normal mode, the ROM 24b is provided with a winning table used for games in the BB mode, games in the RB mode, and the like. In the RB mode, the winning combination determining unit 24d performs a winning determination with reference to the corresponding winning table.

  The medal hopper 59 pays out a prescribed number of payout medals to the medal tray 20 according to the type of winning combination, or adds the prescribed number to the credit counter. A payout table in which the number of payout medals is determined for each type of winning combination is stored in the ROM 24b, and the CPU 24a reads this to drive the medal hopper 59.

  The operation of the pachinko machine 2 configured as described above will be described with reference to the flowchart of FIG. When the main power supply of the slot machine 2 is turned on (step (hereinafter, S) 1), the data reader 34 starts reading data (S2). The CPU 24a collates the data read by the data reader 34 with the authentication data stored in the ROM 24b (S3), and when the coincidence is determined, drives the main body 37a of the solenoid 37 and inserts the driving iron core 37b into the insertion position. The drive iron core 37b is inserted into the iron core insertion recess 35c of the dummy key 35, and the dummy key 35 is held so as not to be removed from the key insertion hole 31c (S4). An alarm sound is generated from the speaker 22 until the switch is operated (S5). When the administrator of the game hall where the slot machine 2 is installed changes the setting value of the slot machine 2, the main power of the slot machine 2 is turned off (S6), and the driving iron core 37b is moved to the insertion release position. Let When the driving iron core 37b is moved to the insertion release position, the dummy key 35 can be removed from the key insertion hole 31c. Then, the dummy key 35 is removed from the key insertion hole 31c (S7). Next, the setting change key 33 is inserted into the key insertion hole 31c of the key cylinder 31 to unlock the key lock mechanism (table selection permission means) (S8), and the rotating portion 31b is rotated to the ON position (S8). S9) After that, when the main power supply of the slot machine 2 is turned on by operating the power switch 30 (S10), since the coincidence between the data read by the data reader 34 and the authentication data stored in the ROM 24b is not determined, the CPU 24a Then, an alarm sound is generated from the speaker 22 (S11). In order to stop the generation of the alarm sound from the speaker 22, a stop switch (not shown) is operated (S12). The CPU 24a stops generating an alarm sound from the speaker 22 in response to the operation of the stop switch (S13). In the present embodiment, when the alarm sound is generated from the speaker 22, the stop switch is operated (S12) to stop the alarm sound from the speaker 22 (S13). The control stop program for stopping the control of the slot machine 2 is started so that the following steps (S14) to (S24) cannot be performed. Even when the alarm sound from the speaker 22 is continuously generated without operating the stop switch, the control stop program described above is not started, and the process proceeds to the following steps (S14) to (S24). You may be able to do that.

  After the rotating unit 31b is rotated to a position where it is turned on (S9) and the main power supply of the slot machine 2 is turned on by operating the power switch 30 (S10), the set value is displayed on the credit number display unit 17. Then, the setting change program 47 is activated and the setting value can be changed (S14). Then, the setting change button 32 is operated to change the setting value (S15). For example, when the setting value before change is “3” and the setting value is changed to “6”, if the setting change button 32 is operated three times, the setting value becomes “3 → 4 → 5 → 6”. It is changed in order, and the set value becomes “6” after three operations. At this time, the manager of the game hall can change the setting value while checking the setting value displayed on the credit number display unit 17.

  When the start lever 18 having a confirmation switch function for confirming the set value is operated after changing the set value from “3” to “6” (S16), the set value “6” is confirmed (S17) and the rotating unit 31b. Is rotated to a position where it is turned off (S18), the set value is set to a set value fixed state that cannot be changed other than “6”, and the set value displayed on the credit number display unit 17 is not displayed ( S19), the operation relating to the setting change is completed, and based on the setting change program 47, the sixth winning table 46 corresponding to the setting value “6” is selected, and the lottery probability for the lost and plural types of winning combinations is set. This means that the lottery probability of the third winning table 53 corresponding to the value “3” is changed to the lottery probability of the sixth winning table 46 corresponding to the set value “6”. When the setting change key 33 is removed from the key insertion hole 31c (S20) and the dummy key 35 is inserted into the key insertion hole 31c (S21), the data reader 34 reads the identification data stored in the IC chip 36 of the dummy key 35, The CPU 24a collates the data read by the data reader 34 with the authentication data stored in the ROM 24b (S22), and when a match is determined, the CPU 24a drives the main body 37a of the solenoid 37 to drive the driving iron core 37b. To move the drive iron core 37b into the iron core insertion recess 35c of the dummy key 35 and hold the dummy key 35 so as not to come out of the key insertion hole 31c (S23). An alarm sound is generated from the speaker 22 (S24).

  As described above, it is possible to insert the key cylinder into the key insertion hole 31c at normal times (when the main power of the slot machine 2 is on and the setting is not changed, for example, when the game hall is in operation) When the main body portion 35a of the dummy key 35 formed in a shape that cannot be unlocked by the key lock mechanism (table selection permission means) 31 is inserted into the key insertion hole 31c, it is read by the data reader 34 by the CPU 24a. The match is determined by collating the data with the authentication data stored in the ROM 24b, and the CPU 24a drives the main body 37a of the solenoid 37 and moves the driving iron core 37b to the insertion position in response to the match. The lever iron core 37b is inserted into the iron core insertion recess 35c of the dummy key 35 so that the dummy key 35 cannot be removed from the key insertion hole 31c. Therefore, a wire, a piano wire, or the like is inserted through the gap between the storage box 4 and the front door 5, and the wire is inserted into the key insertion hole 31c to unlock the key lock mechanism of the key cylinder 31, and the rotating portion 31b. Rotate to the position where it is turned on so that the setting value can be changed, and the setting value cannot be changed illegally, and the illegal setting value can be prevented from being changed.

  If the dummy key 35 is not inserted into the key insertion hole 31c when the main power of the slot machine 2 is on, the CPU 24a compares the data read by the data reader 34 with the authentication data stored in the ROM 24b. Since the match is not determined and the CPU 24a generates an alarm sound from the speaker 22 in response to the determination that the match is not determined, the person who performs the fraudulent action turns off the main power supply of the slot machine 2 and drives the iron core 37b. When the main power supply of the slot machine 2 is turned on in order to illegally change the set value after the dummy key 35 is removed from the key insertion hole 31c by moving the key to the insertion release position, the CPU 24a inserts the dummy key into the key insertion hole 31c. Since the alarm sound is generated from the speaker 22 in response to the fact that 35 is not inserted, the game hall manager The alarm sound is generated from the mosquito 22, it can recognize that the change of incorrect settings were made. Furthermore, the data reader 34 is in an on state (detection state) in which data is read by an operation of a switching button that can be operated only by a hall computer that manages and manages the entire amusement hall, and in an off state (non-read state) in which no data is read. Since the game area manager can operate the switching button, the data reader 34 is turned on (detected state) in which data is read, and off state in which data is not read. (Non-detection state).

  In the above-described embodiment, the state notification unit is configured from the speaker 22, but is not limited thereto, and may be configured from an LED or the like as long as it can notify the state, and can be changed as appropriate. .

  In the above embodiment, the key cylinder 31 is provided with the key lock mechanism as the table selection permission unit. However, when the dummy key 35 is inserted into the key insertion hole 31c, the setting value is changed (first to sixth winning selections). It is only necessary to be able to select a winning table from among the tables 41 to 46). For example, when the dummy key 35 is rotated by inserting the dummy key 35 into the key insertion hole 31c, the rotating portion 31b may be idle. Further, a setting switch is provided in the key insertion hole 31c. When this setting switch is pressed, the setting value can be changed. When the setting change key 33 is inserted into the key insertion hole 31c, the setting switch The setting change key 33 and the dummy key 35 may be formed so that the setting switch is not pressed when the dummy key 35 is pressed and inserted into the key insertion hole 31c.

  Furthermore, in the above embodiment, a solenoid 37 is provided as a dummy key holding means that holds the dummy key 35 and cannot be removed from the key insertion hole 31c, and the driving iron core 37b is moved to the insertion position by the main body portion 37a. The iron core 37b is inserted into the iron core insertion recess 35c of the dummy key 35, and the dummy key 35 is held so as not to come out of the key insertion hole 31c of the key cylinder 31, but the dummy key 35 is not limited to this, and the dummy key 35 is inserted into the key cylinder. For example, the dummy key 35 may be formed of iron and the dummy key 35 may be held by magnetic force, and further, the dummy key 35 may be provided with an insertion hole. Provided, the dummy key 35 may be held by inserting a lock rod into the insertion hole, One in which Yibin be changed.

In this embodiment, the dummy key 60 includes a main body portion (insertion portion) 60a and a foldable folding portion (exposing portion) 60b formed integrally with the main body portion 60a. The main body portion 60a has a key insertion hole. Although it can be inserted into 31c, the key lock mechanism of the key cylinder 31 cannot be unlocked. The bent portion 35b is bent between a linear position (see FIG. 9A) that forms a linear shape with the main body portion 35a, and a bent position (see FIG. 9B) bent 90 ° from the linear position. be able to. On the front surface of the cover portion 29a of the power supply box 29, a convex receiving rib 29e is formed to be received by the bent portion 35b bent to the above-described bending position, and a monitoring switch (detecting means) is provided on the receiving rib 29e. 61 is provided. The monitoring switch 61 is connected to the CPU 24a of the main board 24. As shown in FIG. 9A, when the main body 60a of the dummy key 60 is inserted into the key insertion hole 31c, the monitoring switch 61 is in a switch-off state (non-detection state), as shown in FIG. 9B. When the bent portion 60b is bent to the bent position, the monitoring switch 61 is pressed and is switched on (detected state). When the monitoring switch 61 is switched on, it sends a switch-on signal to the CPU 24a of the main board 24. Based on the switch-on signal sent from the monitoring switch 61, the CPU 24a drives the solenoid 37, moves the driving iron core 37b to the insertion position, and inserts the driving iron core 37b into the iron core insertion recess 35c of the dummy key 35. Thus, the dummy key 35 is prevented from being removed from the key insertion hole 31c. In this embodiment, the monitoring switch 61 is switched between a switch-on state (detected state) and a switch-off state (non-detected state) depending on whether the bent portion 60b of the dummy key 60 is positioned at either the linear position or the bent position. Can be switched.
