Description

  The present invention relates to a gaming machine having a door that opens and closes the inside of the gaming machine main body, and a selection operation for selecting one from a plurality of types of lottery tables having different winning probabilities.

  In this specification, a pachislot machine is described as an example of one of the gaming machines, so that explanation is given using medals as gaming media, but the gaming media includes other media such as coins and pachinko balls. In addition, “inserting a medal (game medium)” includes inserting a bet with a bet button or the like in addition to actually inserting a medal into the medal slot. In addition, the state where the symbols are aligned on the winning line is the winning state, and the state where the winning combination is drawn by lottery (hereinafter referred to as the winning combination lottery) to determine the winning combination in the state prior to winning. And

  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.

  The pachislot machine has, for example, a plurality of types of lottery tables with different winning probabilities of winning combinations, and depending on which lottery table is used to perform the winning combination lottery, the ratio of the number of medals paid out to the number of medals inserted, so-called A payout rate is determined. The payout rate is associated with a value called a set value on a one-to-one basis, and when changing the set value, the door for opening and closing the inside of the pachislot machine body is opened. By setting the set value for each pachislot machine, there is a merit that a business profit can be secured for the game arcade and that the game can be played fairly for the player. Furthermore, since there is a pleasure for a player to guess a pachislot machine having a setting value with a relatively high payout rate, the setting value is important in terms of excitement of gaming.

By the way, in recent years, a so-called goto act has been performed in which the setting value is illegally changed by a method different from the regular method, and this has resulted in a loss of profit. If a goto act is performed, the fairness of the game is lost, so that the game hall may suffer a loss of profit due to a decrease in players in addition to a direct loss of profit due to the goth act. For this reason, it is one of the important issues for pachislot machine manufacturers to take countermeasures against the goto action. For example, in the pachislot machines of Patent Document 1 and Patent Document 2, the above-described door is closed. It has been proposed to disable this operation if the set value is changed. As a result, it is possible to prevent a goofing action of changing a set value by inserting a foreign object such as a wire from a hole opened in the door.
JP 2004-135443 A JP 2004-135844 A

  However, Goto acts are becoming more and more malicious every year, and their methods are diversifying. As one of the methods of gotoing, for example, a method is known in which the door is unlocked using a foreign object such as a duplicated door key or wire, and the unlocked door is opened to change the set value. If this method is used, it is impossible for the pachislot machine to determine whether the set value has been changed normally or whether the set value has been changed by the goto action. I had to find it. However, since goto acts are usually performed in a short period of time, it is difficult to detect goto acts from the player's behavior, and to perform goto acts on players who play games in a legitimate manner. It may be necessary to check whether or not this is done. This causes a player who plays a game in a regular manner to lose interest in the game, which is a cause of a decrease in the number of players who perform a game and a decrease in the profit of the game hall.

  An object of this invention is to provide the gaming machine which can prevent the goto act which changes a setting value illegally.

The gaming machine of the present invention has a door that opens and closes the inside of the gaming machine main body and an opening detection means that detects opening and closing of the door, opens the door , turns on the setting key switch, and turns on the power switch. Then, the mode changes to the setting change mode , and under the setting change mode , a selection for selecting any one of a plurality of setting values associated with each of a plurality of types of lottery tables having different winning probabilities operation are possible, in the setting key switch gaming machine the setting change mode and to turn off you exit, said door in response to the setting key switch in a state where the door is opened is turned off start the opening time of the measurement, an open time measuring means to stop measuring in response the opening time of the door that said door is closed is detected by the open detection means, opening of the door In response to the measurement between is completed, the a determining exceed judging means judges whether the opening time is preset reference time or longer, an input operation unit for inputting the reference time, the opening time Operation invalidating means for invalidating the setting value selected by the selection operation when the reference time is not satisfied.

The door includes an opening angle detecting means for detecting whether or not the opening angle of the door is equal to or larger than a preset reference angle, and the opening time measuring means is configured so that the opening angle is equal to or larger than the reference angle. Preferably, the measurement of the opening time is started in response to the key switch being turned off .

  Moreover, it is preferable to provide a notifying means for notifying that the opening time has not reached the reference time.

(Explanation of terms used in claims)
The “game machine main body” refers to a unit in which a device for executing a game (for example, a reel unit, a liquid crystal unit, a hopper device, etc.) or a substrate for controlling the drive of this device is stored in a storage box. .
Further, the “winning” is not limited to one type, and may be constituted by a plurality of types of hitting. When multiple types of winning are set, it is sufficient that at least any one winning probability differs between lottery tables.
Further, “invalid” indicates that even if a lottery table selection operation is performed, a process for responding to the selection operation is not performed. In order to invalidate the selection operation, for example, even if a selection operation is performed, the lottery table Appropriate measures can be taken, such as not selecting or not setting the lottery table selected by the selection operation.

  In the gaming machine of the present invention, when the opening time of the door does not reach the reference time, the selection operation of the lottery table is invalidated. It becomes impossible to do it at home, and it becomes easier to find a player who performs the goto act. As a result, it is possible to prevent a goofing action that changes the set value illegally.

  When the door opening angle is greater than or equal to the reference angle, the door opening time measurement is started, so it is possible to increase the action when changing the setting value, and find the player who performs the goto action It becomes easy.

  Since it is notified that the opening time of the door has not reached the reference time, it is not necessary to confirm whether or not the goto action has been performed, and the player who has performed the goto action can be immediately found.

  As shown in FIG. 1, the slot machine 10 includes a slot machine main body 11 and a front door 12. The slot machine main body 11 includes a storage box 11a. The storage box 11a stores a device for executing a game, such as first to third reels 15a to 15c, which will be described later, and a substrate for controlling the driving of the device. The front door 12 is divided into two parts in the vertical direction, and consists of an upper door 12a and a lower door (door) 12b. The inside of the slot machine main body 11 is opened and closed by an upper door 12a and a lower door 12b.

  A display window 14 is provided on the upper door 12a. A first reel 15a, a second reel 15b, and a third reel 15c are provided in the back of the display window 14. A plurality of types of symbols are arranged on the outer peripheral surfaces of the first to third reels 15a to 15c, and three symbols per reel are displayed through the display window 14 when the reels stop. Then, the winning combination lottery result is displayed by the combination of symbols displayed from the display window 14.

  Below the display window 14, a display device (notification means) 16 for displaying numbers, specific alphabets, and the like is provided. The slot machine 10 includes six types of lottery tables used in the winning combination lottery. The lottery tables have different winning probabilities for winning combinations. The ratio of the number of paid-out medals to the number of inserted medals, that is, the payout rate, changes depending on which lottery table is used to perform the winning combination lottery. The payout rate changes in a range of 6 steps corresponding to each lottery table, and each payout rate is associated with a value called a set value. The set value is composed of six stages of settings 1 to 6 so as to correspond to each payout rate. Settings 1 to 6 are associated with each payout rate so that the payout rate increases in the order of setting 1 → setting 2 → setting 3 → setting 4 → setting 5 → setting 6. The display device 16 displays a setting value selected by the setting value selection operation and an error display when an error occurs.

  The lower door 12b has a medal slot 17, a start lever 18 that is pressed when the rotation of the first to third reels 15a to 15c is started or when a selected set value is confirmed, and a first reel that stops the rotating reel. 1st-3rd stop button 19a-19c etc. are provided.

  A cylinder 20 is provided on the front side of the lower door 12b. When a dedicated door key is inserted into the cylinder 20 and rotated, the locking of the lower door 12b is released. Thereby, the inside of the slot machine main body 11 can be opened by rotating the lower door 12b. Further, when the engagement between the slot machine main body 11 and the upper door 12a is released with the lower portion of the slot machine main body 11 opened, the upper door 12a can be rotated.

  As shown in FIG. 2, the slot machine main body 11 is provided with a setting selection device 41 that is used when a selection operation for selecting one of six setting values is performed. The setting selection device 41 is provided inside the slot machine body 11, and is exposed to the outside when the lower door 12b is rotated.

  As shown in FIG. 3, the setting selection device 41 is formed in a box shape. On the front of the setting selection device 41, a setting key switch 41a for switching whether or not to select a setting value, a power switch 41b for switching on / off the power, a setting selection button 41c for selecting a setting value, and a setting value switch A reference time input button (input operation means) 41d for inputting a reference time used when determining whether the selection operation is invalid or valid is provided, and an input switching button 41e for switching whether to use the reference time input button 41d. It has been.

  The setting key switch 41a is composed of a key cylinder. When performing a setting value selection operation, the setting selection key 42 is inserted into the setting key switch 41a after the lower door 12b is opened. When the power switch 41b is turned off, the opening time of the lower door 12b is determined. Thereafter, when the setting selection key 42 is turned from the off position to the on position to turn on the power switch 41b, whether or not the open time determined when the power switch 41c is turned off is equal to or longer than the reference time. Determined. When the opening time of the lower door 12b is equal to or longer than the reference time, the setting change mode is entered. When the setting change mode is entered, the operation of the setting selection button 41c is validated. When the operation of the setting selection button 41c is validated, the inserted medal is not accepted and it becomes impossible to play a game.

  When the setting selection button 41c is pressed during the setting change mode, the setting value is selected. When the setting selection button 41c is pressed, six stages of setting values are sequentially set in the order of setting 1 → setting 2 → setting 3 → setting 4 → setting 5 → setting 6 → setting 1. It will be selected. When the start lever 18 is pressed after selection of the setting value with the setting selection button 41c is completed, the setting value selected with the setting selection button 41c is confirmed. After the setting value is confirmed, the setting selection key 42 is turned to the off position and the lower door 12b is closed, and the setting value selection is completed.

  As described above, in the slot machine 10, whether or not to validate the operation of the setting change button 41c is determined depending on whether or not the opening time of the lower door 12b is longer than the reference time. The reference time used in the determination is input in advance by the reference time input button 41d. The reference time input button 41d is activated when the input switching button 41e is pressed. When the reference time input button 41d is pressed, the reference time is incremented by, for example, 10 seconds for each push. When the input switching button 41e is pressed after inputting the reference time, the input reference time is fixed. In order to input the reference time again, the input switching button 41e may be pressed. The means for inputting the reference time and its mode may be set as appropriate.

  As shown in FIG. 2, a shield plate 50 bent in a substantially arcuate plate shape is attached to the back surface of the lower door 12b. The shielding plate 50 is attached so that the end face on one end side in the longitudinal direction extends perpendicularly to the lower door 12b and bends to the hinge side of the lower door 12b. Inside the slot machine main body 11, an open detection member 51 that faces the end face of the shielding plate 50 is provided. The opening detection member 51 is formed in a box shape, and an opening 51 a is formed on the surface facing the shielding plate 50. Inside the opening detection member 51, a passage 51 b that communicates with the opening 51 a and bends in accordance with the shape of the shielding plate 50 is formed. The opening 51 a and the passage 51 b are formed to be slightly larger than the shielding plate 50. The shielding plate 50 is stored in the passage 51b when the lower door 12b is closed, and is set to a length that allows the lower door 12b to escape from the passage 51b when the opening angle of the lower door 12b exceeds a preset reference angle. The reference angle may be set as appropriate, and the length of the shielding board 50 may be adjusted to set the reference angle.

  An opening detection sensor (opening angle detection means) 52 is provided in the vicinity of the opening 51a on the wall surface of the passage 51b. The open detection sensor 52 includes a light receiving element 52a and a light projecting element 52b, and is attached to upper and lower wall surfaces of the passage 51b so as to face each other. When the lower door 12b is closed, the light from the light projecting element 52b is blocked by the shielding plate 50. The light receiving element 52a and the light projecting element 52b are arranged so that the light blocking by the shielding plate 50 is released when the lower door 12b is opened to the reference angle, and the light receiving element 52a receives the light from the light projecting element 52b. Has been. The measurement of the reference time described above is started when the opening angle of the lower door 12b exceeds the reference angle.

  A lower door opening / closing switch 53 facing the lower door 12b is attached to the side wall of the storage box 11a. The lower door opening / closing switch 53 is turned on when pressed by the back surface of the lower door 12b when the lower door 12b is closed, and is turned off when the lower door 12b is opened. Thereby, it is detected whether or not the lower door 12b is opened. It is impossible to play a game when the lower door 12b is opened.

  As shown in FIG. 4, the operation of the slot machine 10 is basically controlled by a control unit 62 including a CPU (excess determining means and operation invalidating means) 60 and a memory 61. In addition to the CPU 60 and the memory 61, the control unit 62 is provided with an electronic lottery unit 70, a winning combination determining unit 71, and a timer (opening time measuring means) 74, which will be described later. In the ROM area of the memory 61, a game execution program for performing a process for executing a game, a setting selection execution program for performing a process for executing a setting value selection operation, and various displays from the display device 16 are displayed. Data to be performed and the like are stored, and the CPU 60 reads out these programs to perform processing related to each operation.

  The medal sensor 63 detects a medal inserted from the medal insertion slot 17 and inputs a medal detection signal to the CPU 60. The CPU 60 counts the number of medals based on the detection signal from the medal sensor 63, and thereby determines the number of valid activated pay lines. The start signal sensor 64 inputs a game start signal to the CPU 60 when the start lever 18 is operated. In response to this, the CPU 60 rotates the first to third reels 15a to 15c. The rotation and stop control of the first to third reels 15 a to 15 c are performed by the CPU 60 and the reel drive controller 65. The stop button sensors 66a to 66c input a stop signal for each reel to the CPU 60 when the stop buttons 19a to 19c are operated. In response to this, the CPU 60 and the reel drive controller 65 perform stop control of the first to third reels 14a to 14c. The hopper device 67 is actuated when a winning combination that involves paying out medals is won. When the hopper device 67 is driven, a prescribed number of medals are paid out according to the type of winning combination.

  The CPU 60 operates the electronic lottery unit 70 in response to the game start signal. The electronic lottery unit 70 includes a random number generator and a random number 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 71. In the winning combination determination unit 71, the type of winning combination is determined according to the input random value.

  The winning combination determining unit 71 is provided with a lottery table 72. In the lottery table 72, all random numbers generated by the random number generator of the electronic lottery unit 70 are grouped into a plurality of numerical ranges, and a winning combination or a loss is assigned to each group. Then, the type of winning combination is determined depending on which winning combination the sampled random number value belongs to. Note that if the sampled random value is a value belonging to the group to which the loss is assigned, it is lost.

  The lottery table 72 is provided with six types of first to sixth setting tables 73a to 73f associated with six stages of setting values. The first to sixth setting tables 73a to 73f have different numerical ranges of random numbers to which the winning combinations are assigned so that the winning probabilities of the winning combinations are different from each other. For this reason, the payout rate of the slot machine 10 changes depending on which of the first to sixth setting tables 73a to 73f the random number sampled by the electronic lottery unit 70 is checked.

  Of the first to sixth setting tables 73a to 73f, the first setting table 73a has the lowest payout rate, and the winning is such that the payout rate increases in the order of the second, third, fourth, fifth and sixth setting tables. The winning probability of the role is set. When setting 1 is selected, the first setting table 73a is selected. When setting value 2 is selected, the second setting table 73b is selected. When setting value 3 is selected, the third setting table 73c and the setting value 4 are selected. The fourth setting table 73d is sometimes used, the fifth setting table 73e is used when the setting value 5 is selected, and the sixth setting table 73f is used when the setting value 6 is selected.

  The CPU 60 includes a setting key switch 41a, a power switch 41b, a setting selection button 41c, a reference time input button 41d, an operation signal from the input switching button 41e, a light reception signal from the light receiving element 52a, an on signal for the lower door opening / closing switch 53, and the like. Is entered. Then, the CPU 60 performs processing associated with the setting value selection operation in response to each signal.

  When the light receiving element 52a receives light from the light projecting element 52b, a light reception signal is input from the light receiving element 52a to the CPU 60. The CPU 60 detects whether or not the opening angle of the lower door 12b exceeds the reference angle depending on whether or not a light reception signal is received. When it is detected that the opening angle of the lower door 12b exceeds the reference angle, the timer 74 is activated. Then, the CPU 60 stores the time of the timer 74 in a non-volatile memory, so-called flash memory (not shown), when the OFF signal of the power switch 41b is input. Thereafter, when the ON signal of the power switch 41b is input, the CPU 60 reads the time stored in the flash memory, and identifies whether the read release time is equal to or longer than the reference time, thereby entering the setting change mode. It is determined whether or not to shift, that is, whether or not to validate the operation of the setting selection button 41c. Note that the CPU 60 also stores the reference time input by the reference time input button 41d in the flash memory.

  When the setting selection button 41c is operated and the operation signal is input, the CPU 60 causes the display device 16 to display the setting value selected by the setting selection button 41c. For example, the setting value is “−1−” when setting 1 is set, “−2” when setting 2 is set, and “−3−3” when setting 3 is set. “−4” when setting 4 is set, “−5−” when setting 5 is set, “−6−” when setting 6 is set, and so on. (Set value) — ”is displayed from the display device 16. The CPU 60 displays these indications every time the setting selection button 41c is pressed: “−1−” → “-2-” → “-3-” → “−4” → “−5-” → “− Switching in the order of “6-” → “-1-” →. When the selected setting value is confirmed by pressing the start lever 18, the CPU 60 causes the display device 16 to display the setting value determined in the form of “(setting value)” (− is not displayed). .

  Further, in response to the operation signal of the setting selection button 41c, the CPU 60 identifies the first to sixth setting tables 73a to 73f corresponding to the setting values selected by the setting selection button 41c. When the start lever 18 is pressed, the types of the selected first to sixth setting tables 73a to 73f are written in the RAM area of the memory 61, and the set values are determined. Thereby, the selection of the set value is completed. When a game is played, the CPU 60 refers to the RAM area of the memory 61 and identifies the type of setting table for collating the random value sampled by the electronic lottery unit 70. Then, the winning combination lottery is performed using the identified first to sixth setting tables 73a to 73f.

  Next, the flow of setting value selection operations and the flow of processing associated therewith in the slot machine 10 configured as described above will be described. First, the operator sets a reference time in advance by operating the reference time input button 41d and the input switching button 41e. The CPU 60 writes the set reference time in the RAM area of the memory 61.

  As shown in FIG. 5, in order to perform a setting value selection operation in the slot machine 10, first, the lower door 12b is unlocked and the lower door 12b is opened. When the opening angle of the lower door 12b exceeds the reference angle, the timer 74 is activated and the opening time of the lower door 12b is measured. When the power switch 41b is turned off after the lower door 12b is opened, the CPU 60 stores the time of the timer 74 when the power switch 41b is turned off in the flash memory. The operator inserts the setting selection key 42 into the setting key switch 41a, rotates the setting selection key 42 to the ON position, and turns on the power switch 41b. When the power switch 41b is turned on, it is determined whether or not the opening time of the lower door 12b is longer than the reference time. After the determination is completed, the CPU 60 clears the release time stored in the flash memory.

  When the opening time of the lower door 12b is equal to or longer than the reference time, the CPU 60 reads the setting selection execution program from the memory 61 and shifts to the setting change mode. When the mode is changed to the setting change mode, the setting value being set is displayed from the display device 16. In the setting change mode, the CPU 60 accepts an operation signal for the setting selection button 41c when the setting selection button 41c is pressed. Thereby, the operation of the setting selection button 41c is validated. When the setting selection button 41c is pressed, the CPU 60 identifies the first to sixth lottery tables 73a to 73f corresponding to the setting value selected at this time. When the start lever 18 is pressed after the selection of the setting value is completed, the CPU 60 writes the first to sixth lottery tables 73a to 73f corresponding to the selected setting value in the RAM area of the memory 61. Thereby, the selected set value is confirmed. When the setting selection key 42 is turned to the off position, the setting change mode ends. When it is detected that the lower door 12b is closed, the CPU 60 reads out the game execution program from the memory 61 and makes it possible to play a game.

  When the opening time of the lower door 12b does not reach the reference time, the CPU 60 invalidates the operation of the setting selection button 41c without shifting to the setting change mode. Then, the CPU 60 causes the display device 16 to display an error display indicating that the power switch 41b is turned off before the opening time of the lower door 12b is equal to or longer than the reference time. When the opening angle of the lower door 12b does not exceed the reference angle, the CPU 60 does not shift to the setting change mode and makes it impossible to select a setting value. In addition, the method for canceling the error display is appropriately set, for example, by closing the lower door 12b, pressing the error recovery button, or rotating the door key inserted into the cylinder 20 in the direction opposite to the unlocking direction. It's okay.

  In the above embodiment, it is determined whether or not the opening time of the lower door 12b is equal to or longer than the reference time in conjunction with the transition to the setting change mode. The trigger for making this determination is during the setting change mode or the end of the setting change mode. It may be set as appropriate, for example. Moreover, you may combine these opportunities.

  For example, when the determination is made during the setting change mode, as shown in FIG. 6, when the power switch 41b is turned on, the timer 74 starts counting, that is, the lower door 12b is opened. Then, after the power switch 41b is turned on, it is determined whether or not the opening time of the lower door 12b is equal to or longer than the reference time when the setting selection button 41c is first pressed. When the opening time of the lower door 12b is equal to or longer than the reference time, the operation of the setting selection button 41c is validated thereafter. If the opening time of the lower door 12b does not exceed the reference time, the operation of the setting selection button 41c is invalidated and an error is displayed.

  For example, when the determination is made at the end of the setting change mode, as shown in FIG. 7, the timer 74 starts measuring when the setting key switch 41a is turned off after the setting value is selected. Then, when the lower door opening / closing switch 53 is turned on, that is, when the lower door 12b is closed, it is determined whether or not the opening time of the lower door 12b is longer than the reference time. In this example, the types of the first to third lottery tables 73a to 73f corresponding to the setting value selected by the setting selection button 41c are written according to the determination result. When the opening time of the lower door 12b is equal to or longer than the reference time, the types of the first to third lottery tables 73a to 73f corresponding to the setting value selected by the setting selection button 41c are written in the memory 61, and the setting selection button The set value selected in 41c is validated. Further, when the opening time of the lower door 12b is less than the reference time, the type of the first to third lottery tables 73a to 73f corresponding to the setting value selected by the setting selection button 41c is set in the memory 61 without being written. The setting value selected by the selection button 41c is invalidated and an error is displayed.

  In the above embodiment, whether or not the opening angle of the lower door 12b exceeds the reference angle is detected by the shielding plate 50 and the opening detection sensor 52. For example, a sensor that detects the amount of rotation of the lower door 12b is a hinge of the lower door 12b. The opening angle of the lower door 12b may be detected by an appropriate method, such as calculating the opening angle from the amount of rotation of the lower door 12b.

  In the above embodiment, the display device 16 is used as the notification means, and when the opening time of the lower door 12b is less than the reference time, an error is displayed by the display device 16. However, as the notification means, for example, outside the slot machine 10 Speakers or lamps may be provided, and errors may be reported using sound or light.
