Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slot machine and a game arcade management system, and more particularly, to a slot machine having an alarm function for outputting an alarm sound when an illegal act is performed, and the above-described slot machine based on a signal output from such a slot machine. The present invention relates to a game arcade management system for coping with an improper act accompanying an alarm function.
[0002]
[Prior art]
A game machine generally called a slot machine is usually played as follows.
[0003]
First, a player inserts a medal, depresses a start lever, and simultaneously drives a plurality of reels (turning drums) simultaneously. After the rotation speed of the reels reaches a predetermined value, the timing is determined so that a desired symbol is derived and displayed on the display window, and the stop button corresponding to each reel is pressed to sequentially stop the rotation of each reel. At this time, if the symbols displayed through the display window form the same arrangement as the predetermined display mode, it is determined that the winning is achieved, and the medals are paid out by the number corresponding to the winning type. This ends one game.
[0004]
In this type of slot machine, winning types such as a big bonus game, a regular bonus game, a single bonus game, and a replay game are provided.
The winning probability (winning rate) of each winning type is a probability value determined based on the winning rate (medal payout rate). The payout rate is a probability value that can be determined in a range of 55 to 120% by rules, and it is recognized that a maximum of six levels of probability values within this range are stored in the slot machine substrate. . Before starting the game, one probability value is selected and set in advance from among the plurality of probability values provided as the payout rate, and until the set probability value is changed, 1 is set. A winning lottery is performed for each game based on the probability value (referred to as a perfect probability method). The set value of the winning rate can be confirmed by a step setting switch described later.
[0005]
In amusement arcades such as pachinko parlors where slot machines are installed, the winning rate can only be set when the power of the slot machine itself is turned on. Instead, it is usual to set the next business day when the store is closed. In this case, the prize rate is set, for example, by referring to the prize rate setting data of the previous day, the distribution of the prize rate in all slot machines in the store, or the number of days since the installation of this model. It is designed to be performed manually.
[0006]
Such amusement arcades have always suffered from damages caused by persons (often called "Goto-shi") who perform actions (illegal acts) that are not appropriate for proper games. Previously, fraudulent acts such as a method of operating a dispensing hopper by inserting a wire or the like into a medal discharge port and a method of adding an action to the rotation of a reel have been problematic. Goto has come up with a new approach due to the devising of various security measures against the United States.
[0007]
In such a trend, there has been a fraudulent activity that has been increasing in recent years, such as taking advantage of the computerization of a winning determination method and changing the setting of a winning rate to one that is advantageous to oneself. . As a trick, for example, setting of a winning rate to be arranged in the housing of the slot machine by unlocking the front frame of the housing or inserting a wire or the like from a gap or opening of the housing of the slot machine. A switch for operating a slot machine (step setting switch, setting button, etc., which will be described later), or an illegal noise such as a radio wave, causing the control system CPU of the slot machine to run out of control and initialize the RAM, thereby winning a prize. May change the setting value of.
[0008]
It is considered that the increase in such misconduct has the following reasons. First, the prize rate is a numerical value that largely affects the return amount to the investment amount, and is a very interesting object for most players who come to the store for the purpose of gain. In addition, since the keys used to operate the stage setting switch (setting keys) and devices that emit illegal noise are illegally on the market, they go beyond the scope of interest and are not professional goto general players Sometimes, the temptation of gains can lead to fraud. Second, once the prize rate setting has been changed to a high value, it seems that it is difficult to detect that the dishonesty has been performed, since then it looks as if the player enjoys the game normally. Can be Therefore, the game can be continued for a long time, and the fraudster has an advantage that the amount that can be fraudulently increases.
[0009]
As described above, the number of fraudulent persons and the amount of fraudulent fraud (the number of medals to be fraudulent) are both increasing. As a result, damages caused by fraudulent operations are overlooked in the management of the store. It is not unusual for money to reach an unreasonable amount, and since the misconduct naturally forms a crime, the amusement arcade management side has to pay a considerable amount of money to prevent and detect such misconduct. And labor must be taken into account, and indeed considerable costs have been allocated.
[0010]
For example, as a system for judging the validity of the number of medals obtained and counted by each person, a hall computer for judging the number of medals held by the player and an ID tag attached to each medal storage box, There is a method in which the number of medals determined by the hall computer is compared with the number of medals actually counted by the medal counter, and if there is a large difference, an alarm is issued (for example, see Patent Document 1). That the majority of players who do not have to monitor the game situation, that the number of slot machines installed increases and the amount of information to be processed increases, and that fraudulent acts were performed only after the game ended. It is difficult to prove that it is recognized (for example, to prove that the set value of the winning rate has been changed, it is the person who made the change It is difficult to prove.) Be such, not a few problems to overcome.
[0011]
In addition, as for a method of changing the set value of the winning rate due to the above-described illegal noise, a slot machine provided with a device for detecting the noise may be used, for example, if the RAM is initialized and the RAM is initialized. There has been developed a device which has a fraud prevention means for determining whether or not the noise is detected, and which has a configuration for notifying if the noise is caused by fraudulent noise (for example, see Patent Document 2). Countermeasures are progressing, including places.
[0012]
As a means to prevent the user from actually changing the set value of the winning rate by operating the stage setting switch, a store clerk patrols the inside of the store, or a monitoring camera is provided in the store to constantly monitor the store. Or methods are widely used. However, in this method, in addition to the capital investment required when introducing the surveillance camera, there is a continuous need for human labor to be involved in the surveillance. Since the method of insertion is hidden and not perceived as a remarkably unnatural behavior, it is difficult to find it visually or with a camera image. I can't get it. That is, this method is not satisfactory from a cost-effective point of view.
[0013]
In addition, a device having a configuration in which a wire or the like cannot be inserted through a gap or an opening of a housing of the slot machine has been devised, but there is no prevention specification for a method of unlocking the front frame of the slot machine with a double key. . Furthermore, it is difficult to discover even if several goto teachers surround one slot machine, make it invisible from the surroundings, and unlock it, even if patrol and camera monitoring are used together. Become.
[0014]
In addition, there is a slot machine configured to detect that the front frame is unlocked and to issue an alarm (for example, see Patent Document 3). However, during business hours, a clerk repairs a jammed medal and collects medals. When the lock is unlocked, the alarm may sound, and it may not be possible to accurately judge whether the lock is valid or not. However, there is still a point to be solved for widespread practical use. In addition, there are also fraudulent acts performed by the clerk alone and fraudulent acts performed by the clerk and Goto in hand.For example, the clerk unlocks the front frame during business hours and the winning rate is advantageous to Goto. It can be said that it is very difficult to determine the validity of unlocking and changing the set value because there is actually a method of changing the setting value.

BEST MODE FOR CARRYING OUT THE INVENTION
(First Embodiment)
FIG. 1 is an external front view of a slot machine 1 according to an embodiment of the present invention.
[0027]
According to FIG. 1, on a front panel 2 of a slot machine 1, a left reel 3, a middle reel 4 and a right reel 5 having various designs drawn on an outer peripheral surface are rotatably provided as display means. Three symbols each, a total of nine symbols, are displayed to the player (not shown) via the display window 6. L1, L2A, L2B, L3A, and L3B are stop lines, which will be described in detail later, and indicate lines that are valid when determining a winning.
[0028]
Above the front panel 2, a winning symbol display section 1A displaying a combination of symbols forming a winning is arranged. Above the winning symbol display section 1A, when a bonus game is won, for example, blinking display A bonus display section 1B is provided to inform the player of the winning.
[0029]
Below the front panel 2, a medal slot 7 for inserting a game medal (hereinafter referred to as a medal), which is a valuable value for playing a game, protrudes from the housing 1 ′ of the slot machine 1. A start lever 8 provided and configured to be depressable and three stop buttons 9, 10, 11 provided corresponding to the respective reels are arranged. , The left reel 3, the middle reel 4 and the right reel 5 start rotating at the same time, respectively. When the left stop button 9 is pressed, the left reel 3 is pressed. When the middle stop button 10 is pressed, the middle reel 4 is rotated. When the right stop button 11 is pressed, the right reel 5 is stopped. Further, at the bottom of the front of the slot machine 1, for example, a speaker 12 that emits a sound effect at the time of a prize or emits a synthesized voice for guiding the order in which the respective stop buttons are pressed, and a predetermined number or more of medals when a prize is won. And a medal payout exit 13 for paying out a medal when the player has made the game.
[0030]
FIG. 2 is a layout diagram showing a configuration inside the housing 1 ′ of the slot machine 1.
[0031]
According to FIG. 2, a reel driving device K incorporating a motor (not shown) rotationally drives a left reel 3, a middle reel 4, and a right reel 5 arranged in parallel in a middle stage inside a housing 1 'of the slot machine 1. Below this, a payout hopper H for paying out medals, a surplus medal storage box B for storing surplus medals, a control of power supply to each part of the slot machine 1 and a winning rate (payout rate). A gaming machine main body power supply device (power supply box) 100 for setting the ball rate) is provided. Further, on an inner wall surface of the housing 1 'adjacent to the reel driving device K, a board case 200 accommodating a main control unit described later and a sub board case 201 accommodating a sub control unit are arranged.
[0032]
Subsequently, an operation of the slot machine 1 during a game will be described.
[0033]
The slot machine 1 starts a game when a player (not shown) inserts medals into the medal insertion slot 7. At this time, if one medal is inserted (one bet), the stop line L1 becomes an active line, and is aligned on the stop line L1 out of the nine symbols displayed via the display window 6 after all the torso are stopped. Only the combination of the three symbols is a target for determining whether or not a winning is achieved. On the other hand, when two medals are inserted (two bets), L2A and L2B are enabled in addition to the stop line L1, and when three medals are inserted (three bets), L3A and L3B are added. All the five stop lines are valid, and combinations of symbols arranged on the valid stop lines are to be determined for winning. Thus, the game condition can be selected by the number of inserted medals.
[0034]
In addition to such a normal game, the slot machine 1 according to the present embodiment may be configured to play a so-called credit game. That is, medals of a predetermined number or less are inserted in the medal insertion slot 7 in advance and accumulated as a valuable value, or medals to be paid out by a prize are paid out from the medal payout port 13 instead of paying out a medal equivalent to the number. By storing the value as a value, if one bet is selected based on this value, the value is reduced by an amount equivalent to one medal. In the case of a single bet, the value may be reduced by an amount equivalent to three medals, and the game may be performed by setting an effective stop line in the same manner as in a normal game.
[0035]
After the determination of the game conditions (determination of the effective stop line), when the player depresses the start lever 8, the reels 3, 4, and 5 start rotating simultaneously. After the rotation speed reaches a predetermined value, the player presses the stop buttons 9, 10, 11 in a predetermined order in anticipation of changes in the symbols displayed one after another via the display window 6, and the reel 3, Reference numerals 4 and 5 sequentially stop the rotation, and the symbols are derived and displayed through the display window 6. At this time, if the combination of the symbols located on the effective stop line out of the nine symbols derived and displayed is the same as the combination displayed on the winning symbol display section 1A, that is, the combination of the symbols related to the winning. In addition, the bonus display unit 1B flashes or the like, or the speaker 12 outputs a sound effect or the like, thereby notifying the winning, and the medal is paid out from the medal payout slot 13 in accordance with the winning type selected. It shifts to a special game state such as a big bonus game.
[0036]
On the other hand, when the combination of the symbols displayed on the effective stop line does not match any of the winning types, the first inserted medal is confiscated, and one game ends without any paid out medal. I do.
[0037]
FIG. 3 is an external perspective view of the power supply box 100.
[0038]
According to FIG. 3, on the outer side of the power supply box 100, a "game mode" for authenticating the setting key 110 engaged when setting the winning rate, and playing a normal game, and setting of the winning rate. And a setting button 102 for selecting a desired prize rate from among the set values of the prize rates provided in the six stages of settings 1 to 6. Along with the means, a function changeover switch 103 for switching ON / OFF of an automatic settlement function and a stop function, a power supply switch 104 for switching ON / OFF of the power of the slot machine 1, and a power plug (not shown) for supplying power to the slot machine 1 are provided. The adapter 105 to be inserted is arranged.
[0039]
The winning rate is always set to one of the set values 1 to 6. The change of the set value of the winning rate is performed in advance before starting the game. First, the setting key 110 is inserted into a keyhole provided in the step setting switch 101, and then the setting key 110 is turned to select the setting mode, Subsequently, the setting is performed by selecting and setting a set value from among predetermined six levels using a set button.
[0040]
FIG. 4 is a schematic block diagram illustrating a schematic configuration of a control system of the slot machine 1.
The control system of the slot machine 1 includes a main control unit 20, a sub control unit 30, and a sound output unit 40, which function as an alarm output unit. The main control unit 20 is housed in the board case 200, and the sub-control unit 30 is housed in the sub-board case 201.
[0041]
The main control unit 20 functions as a game control unit, and includes a CPU (Central Processing Unit) 21 for controlling various operations and a game state of the slot machine 1, various control programs for controlling the CPU 21 and necessary data, For example, a ROM (read-only storage device) 22 storing a winning rate provided in six stages to be described later, a RAM (constant-speed call storage device) 23 for temporarily storing various data and flags, and the like. And a RAM clear device 24 for initializing all data in the RAM 23.
[0042]
Reference numeral 51 denotes an input interface, for example, various signals such as a signal transmitted when the start lever 8 and the stop buttons 9, 10, and 11 are operated, and a signal transmitted when the setting mode is selected by the step setting switch 101. Is converted into an appropriate form for the CPU 21 to recognize and input to the CPU 21. Reference numeral 52 denotes an output interface, which converts various signals processed and transmitted by the CPU 21 into a form suitable for the side receiving the signal to recognize and outputs the converted signal. For example, a signal for controlling a sound effect output according to the game state is converted into an appropriate mode and output to the sub-control unit 30.
[0043]
The sub-control unit 30 includes a sub-CPU 31 for controlling the output of a sound effect accompanying the game generated by the sound output unit 40 and a guidance sound for the progress of the game, and a sub-CPU for temporarily storing various data related to the output. It has a RAM 32, sound data 33 for storing data such as sound effects, and a sound memory 34 for storing data such as guidance sounds.
[0044]
Under the control of the sub CPU 31, the sound output unit 40 reproduces a sound effect or the like based on the data stored in the sound data 33, and outputs a guidance sound or the like based on the data stored in the voice memory 34. It includes an audio synthesis circuit for synthesizing, and an output selection and mixing device 43 for performing output selection and mixing based on outputs from the sound reproduction circuit 41 and the audio synthesis circuit. The signal processed by the output selection and mixing device 43 is sent to the speaker 12 and output as sound.
[0045]
Under the control of the sub CPU 31, the display LED 53 blinks or displays characters or the like in conjunction with an output sound effect or the like, and also displays a set value of a winning rate as described later. The display LED 53 is arranged on the front panel 2 as shown in FIG.
[0046]
FIG. 5 is a flowchart showing an operation performed when the power of the slot machine 1 is turned on. With reference to FIG. 5, the operation of setting the winning rate and the output of the alarm sound will be described in detail. In the following description, all signals input to the main control unit 20 are input via the input interface 51, and all signals output from the main control unit 20 are output via the output interface 52. And will not be mentioned one by one. In the operation of the slot machine 1 during the game and the operation related to the setting of the winning rate, a corresponding signal is generated, and this signal is input to the CPU 21 to be processed. A description of the operation of a device (not shown) that performs output is omitted in the following description. Also, “S” means “step”, for example, S1 indicates step 1.
[0047]
First, before turning on the power of the slot machine 1, the setting key 110 is inserted into the keyhole of the step setting switch 101 (S1). At this time, if there is no need to confirm the current set value of the winning rate or to change the set value, the step setting switch is set to OFF. On the other hand, if it is necessary to confirm the current set value of the winning rate or to change the set value, the setting key switch 101 is set to ON.
[0048]
Next, the power switch 104 is turned on to turn on the power to the slot machine 1 (S2).
[0049]
When the step setting switch 101 is OFF (S3), that is, when the game mode is selected, under the control of the CPU 21, the current setting value n (1 ≦ n ≦ 6) is changed without changing the winning rate setting. The game can be started without any change, and the operation performed when the power is turned on ends (S4).
[0050]
On the other hand, when the step setting switch 101 is ON (S3), that is, when the setting mode is selected, the CPU 21 incorporates the current winning rate set value n stored in the RAM 23 under the control of the CPU 21. (S5), and the current set value n of the winning rate is displayed on the display LED 53 (S6). By visually checking this display, the current set value n of the winning rate can be confirmed. Subsequently, the CPU 21 outputs a control signal to the sub-control unit 30 to generate an alarm (alarm sound). Upon receiving this control signal, the sub CPU 31 controls the sound output unit 40 based on the sound data 33 and / or the predetermined data stored in the sound memory 34 to, for example, sound like a siren or “set value”. Synthesized voice is output from the speaker 12 (S7).
[0051]
At this time, the sub CPU 31 may be configured to perform the interlocking control of the display state of the display LED 53 in accordance with the output of the alarm sound, and adopt a notification method that appeals not only to hearing but also to vision.
[0052]
If the current winning rate setting is only checked and the setting of the winning rate is not changed, after the alarm is generated, the start lever 8 is pressed down (ON) to complete the setting mode (S8) and turned ON. Is turned off (S12), and the mode is switched to the game mode.
[0053]
On the other hand, when changing the current set value n of the winning rate, first, the continuation of the setting mode is selected without depressing the start lever 8 (S8).
[0054]
When the setting button 102 is pressed once (ON) (S9), a signal is sent so as to step up the current winning rate setting value n by 1 and set it to n + 1. Is rewritten to n + 1 (S10), and the rewritten set value n + 1 is displayed on the display LED 53 (S11).
[0055]
If this n + 1 is a desired set value, the start lever 8 is pressed down (S8) to complete the setting mode, and then the stage setting switch 101 is turned off (S12) to switch to the game mode.
[0056]
If n + 1 is not the desired set value, when the set button 102 is turned on again (S9), the set value on the register is stepped up by one again and rewritten to n + 2 (S10), and the display LED 53 displays n + 2. Is performed (S8). After repeating this process until the desired set value is displayed on the display LED 53, the start lever 8 is pressed down (S8), the selection of the set value of the winning rate is completed, and the step setting switch 101 is turned off ( S9) Switch to the game mode. Thus, the operation of changing the winning rate is completed.
[0057]
Since the set value is selected in the range of 1 to 6, if the set button 102 is pressed once when the set value currently displayed on the display LED 53 is 6, it is stored in the register. The set value returns to 1, and the set value displayed on the display LED 53 also returns to 1. That is, the set value of the winning rate is incremented by one each time the setting button 102 is turned on, and cyclically changes from 1 to 6.
[0058]
When OFF is selected by the stage setting switch 101 in S12 and the game mode is switched, the set value of the winning rate stored in the register is stored in a predetermined area of the RAM 23 (S13), and then the RAM clear device 24 An area of the RAM 23 for storing data relating to the playability is initialized (S14). This is because information on the previous game, such as information on the number of remaining medals of the game played on the last slot machine 1 the previous day and information on flags, may still be stored in the RAM 23. This is the process that goes through to erase. Note that the set value of the winning rate stored in S13 is, of course, not cleared. As described above, all the processes to be performed when the power is turned on are completed, and the slot machine 1 is ready to start a game (S15).
[0059]
The slot machine 1 of the present embodiment described above is configured so that an alarm is always output when the stage setting switch 101 is turned on to switch to the setting mode. Even if the user has a condition that allows access to the setting means, such as having the setting value, and is familiar with the setting value change process, an alarm is always output when the change operation is performed. This is the same regardless of whether the person who commits the misconduct is a goto teacher or a clerk at a game arcade. Therefore, according to such a slot machine 1, "the stage setting switch 101 or the setting button 102 is operated during the business hours of the store to change the winning rate setting to one's own advantage, and the game is continued with the setting. Fraudulent acts will always be reported, so it is inevitable that they will be caught.
[0060]
(Second embodiment)
In the slot machine 1, for example, a timer for timing is provided in the main control unit 20, and under the control of the CPU 21, the timing of the timer is started at the same time as the output of the signal related to the occurrence of the alarm, and the timer is set for a predetermined time (at least). It is sufficient to set a time during which the store clerk can go straight to the place where the misconduct has taken place, for example, one minute. A shorter time is required when linking with other security means described later. It is also possible to adopt a configuration in which a signal for stopping the output of the alarm is output when the time is measured, and the alarm is stopped under the control of the sub CPU 31 receiving the signal.
[0061]
According to the slot machine 1 to which such a configuration is added, the output of the alarm is automatically stopped after the elapse of a predetermined time after the occurrence of the alarm, so that the store clerk does not need to perform the operation of stopping the alarm, thereby reducing troublesomeness. At the same time, it is possible to avoid a situation in which a surrounding player must endure an alarm that sounds loudly for a long time, and it is possible to reduce the discomfort experienced by the player.

(Third embodiment)
The slot machine 1 may be provided with an operation prohibiting means for preventing the operation of the start lever 8 and the stop buttons 9, 10, 11 and the like during the alarm output, thereby preventing the game from being continued during the alarm output. Good. Specifically, for example, if the CPU 21 causes an error state of the slot machine 1 to be generated at the same time as the output of an alarm based on a control program stored in the ROM 22, the game related to the game is performed until the error state is released. The operation is determined to be invalid, and an operation prohibition effect can be brought about.
[0063]
According to the slot machine 1 having such an effect, even when the clerk arrives late, for example, even in a situation where the game can be continued even though the alarm is being output, all the game operations are invalidated. The fraud can be prevented, and the store does not suffer any loss.

(Fourth embodiment)
Further, for example, a winning signal such as a signal transmitted in response to the step setting switch 101 being ON in S3 of FIG. 5 or a signal transmitted in response to pressing of the setting button 102 in S9. Utilizing the fact that a signal (operation signal) transmitted in response to an operation performed in accordance with a change in the set value of the rate is input to the CPU 21, the following function as a detection unit is provided to the CPU 21. Becomes possible.
That is, various signals are input to the CPU 21. Each signal is provided with a code that makes it possible to recognize what information the signal corresponds to. The CPU 21 specifies an operation performed by reading this code. For example, the CPU 21 can specify an operation “the setting button has been pressed” from the input signal. Therefore, when the CPU 21 determines that the operation is related to the change of the set value of the winning rate, a program indicating that the signal is generated (or the fact is written in the RAM 23) is stored in the ROM 22. By doing so, the CPU 21 can recognize (detect) that the setting value change operation is actually being performed.
Further, the CPU 21 writes the fact that the setting value change operation has been performed in the RAM 23 and starts timekeeping, and after measuring a predetermined time, generates and outputs a signal indicating that the operation has been performed. You can also. According to this, it is possible to perform a measure such as sounding an alarm after a predetermined time has elapsed from the detection. (Actually, among the contents to be described later, those utilizing the time difference are based on this configuration.)
[0065]
By adopting a signal instructing the occurrence of an alarm as the above-mentioned "signal indicating that" generated when the CPU 21 detects a change in the set value and outputting this signal to the sub CPU 31, the change operation is actually performed. It is possible to notify what is being done. Further, it is also possible to correspond only to a desired signal (for example, pressing of a setting button) among signals corresponding to a setting value changing operation. According to this, it is possible to generate an alarm at a desired timing (pressing of the setting button).
[0066]
(Fifth embodiment)
Further, when other security means other than the alarm output are used together, the CPU 21 of the slot machine 1 having the detection means outputs the detection signal also to the control means for controlling these security means. With such a configuration, it is possible to link these security means with the output of the alarm. Examples of the form of the game arcade management system including the slot machine 1 capable of linking with other security means include the following.
