  The data storage area stores a storage area for storing various data tables, a storage area for storing effect data constituting each effect content, a storage area for storing animation data related to creation of video, and a sound data related to BGM and sound effects. A storage area, a storage area for storing lamp data related to the light on / off pattern, and the like are included.

  The sub control circuit 72 is connected to the liquid crystal display device 18, the speaker 21, and the lamp 29 as peripheral devices whose operations are controlled.

  The sub CPU 81, the rendering processor 84, the drawing RAM 90 (including the frame buffer 91), and the driver 85 create a video according to the animation data designated by the contents of the presentation, and display the created video on the liquid crystal display device 18.

  Further, the sub CPU 81, DSP 86, audio RAM 89, A / D converter 87, and amplifier 88 output sounds such as BGM from the speaker 21 in accordance with the sound data specified by the production contents. Further, the sub CPU 81 turns on and off the lamp 29 according to the lamp data designated by the contents of the effect.

  Further, the sub CPU 81 issues or stops a warning sound by the speaker 21 based on an open information signal or a close information signal including information on whether the front door 9 is opened or closed from the open / close detection device 100. That is, the sub CPU 81 serves as a notification control unit in FIG. Furthermore, the speaker 21 has a role as a notification means in FIG.

  Further, when the sub CPU 81 receives a key information signal from the main CPU 31 of the main control circuit 71 based on a signal from the key sensor 300S, the sub CPU 81 receives a signal (open information signal, close information signal, etc.) from the open / close detection device 100. It is controlled to stop. That is, the main CPU 31 has a role as signal reception stopping means in FIG.

<Electrical configuration of the open / close detection device>
FIG. 10 shows an electrical configuration of the open / close detection device 100 in the present embodiment.

  As shown in FIG. 10, the open / close detection device 100 includes a gyroscope 150 and an open / close detection CPU 106.

  The gyroscope 150 includes an open / close detection sensor 200, an operational amplifier 101, a synchronous detection circuit 102, a filter 103, an amplifier 104, an A / D converter 105, and a transmitter 107.

  As described above, the open / close detection sensor 200 includes the piezoelectric vibrating body 201, the driving piezoelectric elements 201a and 201c, and the detecting piezoelectric elements 201b and 201d. The driving piezoelectric element 201a is applied with an input voltage from the transmitter 107, and vibrates the piezoelectric vibrating body 201 due to a potential difference from the grounded driving piezoelectric element 201c. When the Coriolis force, which is an external force generated by the rotation of the front door 9, is generated in the piezoelectric vibrating body 201, a voltage (referred to as a detection voltage) is generated due to the piezoelectric phenomenon of the piezoelectric vibrating body 201, and the detecting piezoelectric elements 201b and 201d. To the operational amplifier 101.

  The operation amplifier 101 operates and amplifies a minute detection voltage from the detection piezoelectric elements 201b and 201d. The amplified detection voltage is synchronously detected by the synchronous detection circuit 102 and filtered by the filter 103. Thereafter, the detection voltage is amplified by the amplifier 104 and converted into a detection signal digitized by the A / D converter 105.

  The open / close detection CPU 106 calculates a rotation angle Θ from the closed position of the front door 9 based on the detection signal from the A / D converter 105. Thereafter, the open / close detection CPU 106 determines the open / close state based on the calculated rotation angle Θ, and outputs an open information signal or a close information signal to the sub CPU 81. Further, the open / close detection CPU 106 receives the detection signal from the A / D converter 105 and simultaneously counts for 3 minutes, and transmits the count end signal to the sub CPU 81 when the count ends. That is, the open / close detection CPU 106 serves as an open / close detection means in FIG.

  According to the above configuration, the rotation angle when the front door 9 opens and closes is detected by the gyroscope 150 provided on the front door 9 of the pachislot 1, and based on the detected rotation angle of the front door 9, The open / close detection CPU 106 determines whether the front door 9 is open or closed. Further, when the opening / closing detection CPU 106 determines that the front door 9 is in the open state, the speaker 21 notifies the outside. Thereby, for example, when the fraudster opens the front door 9 in order to change the game setting without the administrator of the pachislot 1, the speaker 21 can notify the outside. As described above, since the unauthorized person is notified to the outside simply by opening the front door 9, the unauthorized act can be prevented in advance. Further, since the gyroscope 150 can detect the operation by applying an external force generated when the installed installation surface is tilted or moved, the gyroscope 150 may be installed anywhere within the plane of the front door 9. . Therefore, fraudulent acts can be easily prevented. Further, for example, by installing the front door 9 on the inside of the cabinet 2 to prevent an operation from the outside, the security is also safe.

  In addition, with the above configuration, the operation of the front door 9 can be detected using a vibrating gyroscope. Thereby, since a plurality of parts such as a motor and a bearing are not required, it is a small space and can prevent an illegal act at a low cost.

[Program flow executed in pachislot]
Next, the contents of the program executed by the main CPU 31 of the main control circuit 71 will be described with reference to FIGS.

[Main flowchart by control of main CPU of main control circuit]
First, with reference to FIG. 11, the main flowchart by control of main CPU31 is demonstrated. When power is turned on to the pachi-slot 1, first, the main CPU 31 performs an initialization process (S1). Next, the main CPU 31 clears the designated storage area in the main RAM 33 (S2). For example, data stored in a storage area that needs to be erased for each game, such as an internal winning combination storage area or a display combination storage area, is cleared.

  Next, the main CPU 31 performs a medal acceptance / start check process which will be described later with reference to FIG. 12 (S3). In this process, input checks of the medal sensor 22S and the start switch 6S are performed.

  Next, the main CPU 31 extracts a random value and stores it in a random value storage area provided in the main RAM 33 (S4). Next, the main CPU 31 performs an internal lottery process which will be described later with reference to FIG. 13 (S5). In this process, the internal winning combination is determined by lottery based on a random value. Next, the main CPU 31 transmits a start command to the sub-control circuit 72 (S6). The start command includes a parameter for specifying an internal winning combination.

  Next, the main CPU 31 requests the start of rotation of all main reels (S7). When the start of rotation of all main reels is requested, the driving of the stepping motor 49 is controlled by an interrupt process executed at a constant cycle (1.1173 msec), and the rotation of each reel 3 is started.

  Next, the main CPU 31 performs a reel stop control process which will be described later with reference to FIG. 14 (S8). In this process, the input of the stop switch 7S is checked, and the reel 3 of the corresponding reel 3 is checked based on the timing when the stop button (left stop button 7L, middle stop button 7C, right stop button 7R) is pressed and the internal winning combination. The rotation is stopped.

  Next, the main CPU 31 searches for a combination of symbols displayed along the winning determination line 8, and determines a payout number and the like based on the result (S9). As a result of the search, when the symbol combination displayed along the winning determination line 8 matches the symbol combination defined by the symbol combination table, the corresponding display combination and the number of payouts are determined. Next, the main CPU 31 transmits a display command to the sub control circuit 72 (S10). The display command includes parameters that specify the display combination, the number of payouts, and the like.

  Next, the main CPU 31 performs a medal payout process (S11). Based on the determined payout number, the hopper 40 is driven and the credit number is updated. Next, the main CPU 31 updates the bonus end number counter based on the payout number (S12). The numerical value determined as the payout number is subtracted from the bonus end number counter.

  Next, the main CPU 31 determines whether or not the bonus operating flag is on (S13). When determining that the bonus operating flag is on, the main CPU 31 performs a bonus end check process (S14). It is checked whether or not to end the bonus operation with reference to various counters for managing the bonus end timing.

  The main CPU 31 performs a bonus operation check process after S14 or when it is determined in S13 that the bonus operating flag is not on (S15). It is checked whether or not the bonus operation starts. When this process ends, the process proceeds to S2.

[Medal reception / start check processing]
Next, with reference to FIG. 12, the medal acceptance / start check process will be described. First, the main CPU 31 determines whether or not the automatic insertion counter is 0 (S31). When it is determined that the automatic insertion counter is 0, the medal passage permission is performed (S32). The selector solenoid is driven, and the passage of medals in the selector is prompted.

  When determining that the automatic insertion counter is not 0, the main CPU 31 copies the automatic insertion counter to the insertion number counter (S33). Next, the main CPU 31 clears the automatic insertion counter (S34). S33 and S34 are processes for replaying.

  After S32 or S34, the main CPU 31 sets 3 as the maximum value of the insertion number counter (S35). Next, the main CPU 31 determines whether or not the bonus operating flag is on (S36). When determining that the bonus operating flag is on, the main CPU 31 changes the maximum value of the insertion number counter (S37). For example, the maximum value is changed to 2.

  The main CPU 31 determines whether or not the passage of medals has been detected after S37 or when it is determined in S36 that the bonus operating flag is not on (S38). When determining that the passage of medals has been detected, the main CPU 31 determines whether or not the inserted number counter has reached the maximum value (S39). When determining that the inserted number counter has not reached the maximum value, the main CPU 31 adds 1 to the inserted number counter (S40). Next, the main CPU 31 stores 5 in the effective line counter (S41). Next, the main CPU 31 transmits a medal insertion command to the sub control circuit 72 (S42). The medal insertion command includes a parameter for specifying the number of inserted coins.

  When the main CPU 31 determines in S39 that the inserted number counter is the maximum value, the main CPU 31 adds 1 to the credit counter (S43). The main CPU 31 checks the bet switch 12S after S43, after S42, or when it is determined that the passage of medals is not detected in S38 (S44). A numerical value corresponding to the bet button 12 is added to the inserted number counter while being subtracted from the credit counter.

  Next, the main CPU 31 determines whether or not the insertion number counter has reached the maximum value (S45). When it is determined that the insertion number counter has not reached the maximum value, the process proceeds to S38, whereas when it is determined that the insertion number counter has reached the maximum value, it is determined whether or not the start switch 6S is on (S46). ).

  When determining that the start switch 6S is not on, the main CPU 31 proceeds to S38, whereas when determining that the start switch 6S is on, the main CPU 31 prohibits medal passage (S47). The selector solenoid is not driven, and medals are expelled. When this process ends, the medal acceptance / start check process ends.

[Internal lottery processing]
Next, an internal lottery process will be described with reference to FIG. First, the main CPU 31 determines an internal lottery table and the number of lotteries (S61). The operating flag storage area is referred to, and the internal lottery table and the number of lotteries are determined according to whether or not the bonus is activated. The number of lotteries indicates the number of times that a lottery value is subtracted and a determination is made as to whether a digit has occurred for each winning number defined by the internal lottery table.

  Next, the main CPU 31 obtains a random value stored in the random value storage area and sets it as a determination random value (S62). Next, the main CPU 31 sets 1 as the initial value of the winning number (S63).

  Next, the main CPU 31 refers to the internal lottery table and acquires a lottery value corresponding to the winning number (S64). Next, the main CPU 31 subtracts the lottery value from the determination random number value (S65). Next, the main CPU 31 determines whether or not a digit has been made (S66). When the main CPU 31 determines that the digit is not performed, the main CPU 31 subtracts 1 from the number of lotteries and adds 1 to the winning number (S67).

  Next, the main CPU 31 determines whether or not the number of lotteries is 0 (S68). When the main CPU 31 determines that the number of lotteries is not 0, the process proceeds to S64. On the other hand, when the number of lotteries is determined to be 0, the main CPU 31 sets 0 as the small role / replay data pointer and serves as the bonus data pointer. 0 is set (S69).

  When the main CPU 31 determines in S66 that a digit has been made, the main CPU 31 obtains the small role / replay data pointer and the bonus data pointer according to the current winning number (S70). After S70 or S69, the main CPU 31 refers to the small winning combination / replay internal winning combination determination table and acquires the internal winning combination based on the small winning combination / replay data pointer (S71).

  Next, the main CPU 31 stores the acquired internal winning combination in the internal winning combination storing area (S72). Next, the main CPU 31 determines whether or not the data stored in the carryover combination storage area is 0 (S73). When the main CPU 31 determines that the data stored in the carryover combination storage area is 0, the main CPU 31 refers to the bonus internal winning combination determination table and acquires the internal winning combination based on the bonus data pointer (S74). ). Next, the main CPU 31 stores the acquired internal winning combination in the carryover combination storing area (S75).

  After determining whether the data stored in the carryover combination storage area is not 0 after S75, the main CPU 31 performs a logical OR operation between the carryover combination storage area and the internal winning combination storage area. Is stored in the internal winning combination storing area (S76). That is, the internal winning combination relating to the bonus operation is carried over. When this process ends, the internal lottery process ends.

[Reel stop control process]
Next, the reel stop control process will be described with reference to FIG. First, the main CPU 31 determines whether or not a valid stop button has been pressed (S101). When the main CPU determines that a valid stop button has not been pressed, it waits until it is pressed.

  When the main CPU determines that a valid stop button has been pressed, the main CPU invalidates the operation of the corresponding stop button (S102). The valid and invalid states of each stop button are managed in a predetermined storage area provided in the main RAM.

  Next, the main CPU sets 5 as the number of checks (S103). In the present embodiment, since the maximum number of sliding symbols is “4”, when the stop button is pressed, including the symbol position in the middle of the corresponding display window, Up to the position is subject to check. That is, any one of the five numerical values “0”, “1”, “2”, “3”, and “4” is determined as the number of sliding frames.

  Next, the main CPU, based on the internal winning combination, each check range including the position of the symbol in the middle of the corresponding display window (hereinafter referred to as stop start position) when the stop button is pressed. Among the symbol positions, the symbol position with the highest priority is searched (S104). In this process, the position of the symbol that can display the combination of symbols permitted to be displayed by the internal winning combination along the winning determination line is determined as the position of the symbol with the highest priority.

  Next, the main CPU determines the number of sliding symbols based on the search result (S105). The number of symbols from the stop start position to the symbol position with the highest priority is determined as the number of sliding symbols. Next, the main CPU shifts to waiting for a scheduled stop position (S106). When a transition is made to waiting for the planned stop position, the driving of the stepping motor is controlled by an interrupt process described later, and the rotation of the corresponding reel is stopped after the position of the highest priority symbol reaches the middle stage of the corresponding display window. The

  Next, the main CPU transmits a reel stop command to the sub-control circuit (S107). The reel stop command includes a parameter for specifying the type of the stopped reel.

  Next, the main CPU determines whether or not there is a stop button whose operation is valid (S108). That is, it is determined whether there is a reel that is still rotating. When the main CPU determines that there is a stop button with an effective operation, the main CPU proceeds to S101, whereas when it determines that there is no stop button with an effective operation, the main CPU ends the reel stop control process.

[Process by control of sub CPU of sub control circuit]
Next, contents of various control processes executed by the sub CPU 81 of the sub control circuit 72 will be described with reference to FIGS.

[Notification control processing 1]
First, the notification control process 1 under the control of the sub CPU 81 will be described with reference to FIG. First, the sub CPU 81 determines whether or not an open information signal is received from the open / close detection CPU 106 (A1). When determining that the open information signal has not been received, the sub CPU 81 waits until an open information signal is received from the open / close detection CPU 106. On the other hand, when determining that the open information signal has been received, the sub CPU 81 transmits a notification signal to the speaker 21 and starts notification by the speaker 21 (A2).

  Next, the sub CPU 81 determines whether or not a count end signal has been received from the open / close detection CPU 106 (A3). When the sub CPU 81 determines that the count end signal has not been received, the sub CPU 81 continues the notification by the speaker 21 (A4), and waits until the count end signal is received from the open / close detection CPU 106. On the other hand, when determining that the count end signal has been received, the sub CPU 81 transmits a stop signal to the speaker 21 and stops the notification by the speaker 21 (A5). When this process ends, the notification control process 1 ends.

[Notification control processing 2]
Next, with reference to FIG. 16, the notification control process 2 by the control of the sub CPU 81 will be described. First, the sub CPU 81 determines whether or not a close information signal has been received from the open / close detection CPU 106 (A11). When the sub CPU 81 determines that the closing information signal has not been received, the sub CPU 81 waits until the closing information signal is received from the opening / closing detection CPU 106. On the other hand, when determining that the close information signal has been received, the sub CPU 81 transmits a stop signal to the speaker 21 and stops the notification by the speaker 21 (A12). When this process ends, the notification control process 2 ends.

[Signal reception stop processing]
Next, with reference to FIG. 17, a signal reception stop process by the control of the sub CPU 81 will be described. First, the sub CPU 81 determines whether or not a key information signal has been received from the main CPU 31 (A21). When the sub CPU 81 determines that the key information signal is not received, the sub CPU 81 waits until the key information signal is received from the main CPU 31. On the other hand, when the sub CPU 81 determines that the key information signal has been received, the sub CPU 81 stops receiving the signal from the open / close detection CPU 106 (A22). When this process ends, the signal reception stop process ends.

[Processing by Control of Open / Close Detection CPU of Open / Close Detection Device]
Next, the contents of the processing executed by the open / close detection CPU 106 of the open / close detection device 100 will be described with reference to FIG.

[Open motion judgment processing]
With reference to FIG. 18, the opening operation determination process by the control of the opening / closing detection CPU 106 will be described. First, the open / close detection CPU 106 determines whether a detection signal is received from the A / D converter 105 of the gyroscope 150 (B1). When it is determined that the detection signal is not received, the open / close detection CPU 106 stands by until a detection signal is received from the gyroscope 150. On the other hand, when it is determined that the detection signal is received, the open / close detection CPU 106 calculates a rotation angle Θ from the closed position of the front door 9 based on the detection signal (B2).

  Next, the open / close detection CPU 106 determines whether or not the calculated rotation angle Θ is 10 degrees or more (B3). Note that the reason why the angle Θ is determined by 10 degrees is that it is impossible to contact the device in the housing with a gap of 10 degrees, that is, 10 degrees is an angle at which fraudulent acts cannot be performed. When the opening / closing detection CPU 106 determines that the rotation angle Θ is not 10 degrees or more, it outputs a closing information signal to the sub CPU 81 (B4), and ends this processing.

  On the other hand, when the opening / closing detection CPU 106 determines that the rotation angle Θ is 10 degrees or more, it outputs an open information signal to the sub CPU 81 (B5). Thereafter, the open / close detection CPU 106 starts counting time for 3 minutes (B6). The reason why the count time is 3 minutes is that the time during which an illegal act is performed is notified, and the notification can be ended before it is felt that it is troublesome even if it is notified by mistake.

  Next, the open / close detection CPU 106 determines whether or not the count time has elapsed for 3 minutes (B7). When it is determined that the count time has not elapsed for 3 minutes, the open / close detection CPU 106 continues the count (B8). On the other hand, when it is determined that the count time has elapsed for 3 minutes, the open / close detection CPU 106 outputs a count end signal to the sub CPU 81 (B9). When this process ends, the opening operation determination process ends.

  According to the various processing operations in the pachislot 1 described above, the rotation angle when the front door 9 is opened and closed is detected by the gyroscope 150 provided in the front door 9 of the pachislot 1, and the rotation of the detected front door 9 is detected. Based on the moving angle, the open / close detection CPU 106 determines whether the front door 9 is open or closed. Further, when the opening / closing detection CPU 106 determines that the front door 9 is in the open state, the speaker 21 notifies the outside. Thereby, for example, when the fraudster opens the front door 9 in order to change the game setting without the administrator of the pachislot 1, the speaker 21 can notify the outside. As described above, since the unauthorized person is notified to the outside simply by opening the front door 9, the unauthorized act can be prevented in advance. Further, since the gyroscope 150 can detect the operation by applying an external force generated when the installed installation surface is tilted or moved, the gyroscope 150 may be installed anywhere within the plane of the front door 9. . Therefore, fraudulent acts can be easily prevented. Further, for example, by installing the front door 9 on the inside of the cabinet, it is possible to prevent an operation from the outside, so that the security is also safe.

  Further, the opening / closing detection CPU 106 calculates a rotation angle from a predetermined position of the gyroscope 150 rotated based on the opening / closing operation of the front door 9. Further, when the calculated rotation angle of the gyroscope 150 reaches a predetermined angle, it is determined that the front door 9 is in an open state, and the speaker 21 notifies the outside. Accordingly, by setting the predetermined angle to be notified to an angle at which it is not possible to perform an illegal act, when the front door 9 is in an open state due to an illegal act being performed, When the front door 9 is slightly opened due to rattling of the pachislot 1 or an impact during the game, it is possible to avoid notification. In this way, since it is possible to notify only when an illegal act is performed, it is possible to avoid interfering with other players' games.

Thereby, for example, when the fraudster opens the front door 9 in order to change the game setting without the administrator of the pachislot 1, the speaker 21 can notify the outside. As described above, since the unauthorized person is notified to the outside simply by opening the front door 9, the unauthorized act can be prevented in advance. Further, since the gyroscope 150 can detect the operation by applying an external force generated when the installed installation surface is tilted or moved, the gyroscope 150 may be installed anywhere within the plane of the front door 9. .

Here, the L-shaped member 501 is caused by the tension T generated when the front door 9 is opened and closed.
The base member 504 that has been in contact with is separated from the L-shaped member 501 and does not keep parallel to the front door 9. That is, when the front door 9 is in the open state, the rotating body 601 of the open / close detection sensor 600 and the front door 9 are not kept parallel (see the lower diagram of FIG. 19). That is, the rotating body 601 of the open / close detection sensor 600 is inclined by the angle Θ ′ when the front door 9 is in the closed state and in the open state. By detecting the external force generated thereby, the rotation angle of the front door 9 can be detected.

  As described above, in the pachislo 1 according to the present invention, the gyroscope 150 includes the rotating shaft 602 and the rotating body 601 that rotates about the rotating shaft 602, and the rotating body in the operation of opening and closing the front door 9. A rotary gyroscope that detects the operation of the front door 9 by detecting an external force applied to 601 may be used.

  According to said structure, operation | movement of the front door 9 is detectable using a rotary gyroscope. Accordingly, for example, by using the large and heavy rotating body 601, the detection sensitivity of the gyroscope 150 can be further increased, so that illegal acts can be prevented accurately.

  In the present embodiment, the notification means uses the speaker 21, but the present invention is not limited to this. For example, the notification may be performed by blinking the lamp 29.

  Further, in the present embodiment, the condition of the rotation angle by which the open / close detection CPU 106 determines the open / closed state of the front door 9 is 10 degrees or more. However, in the present invention, the present invention is not limited to this. Any angle that cannot be performed can be set as appropriate.

  In the present embodiment, the open / close detection CPU 106 counts for 3 minutes. However, the present invention is not limited to this, and the time during which an illegal act is performed is notified and The time can be appropriately set as long as the notification can be ended before it is felt that it is troublesome even if the notification is made by mistake.

  The embodiments of the present invention have been described above, but only specific examples have been illustrated, and the present invention is not particularly limited. Specific configurations and the like can be appropriately changed in design.
