Description

  The present invention relates to a gaming machine, and more particularly to a gaming machine having a fraud prevention function and a power saving function.

  Generally known as a pachislot machine, a spinning-type game machine in which medals are used as game media is known. Such a gaming machine has a housing having an opening on the front surface, an opening and closing portion such as a door attached to the housing and capable of opening and closing the opening, and various electrical components such as a control board provided in the housing. have.

  Conventionally, fraudulent acts such as opening and closing a gaming machine, changing a set value, replacing a control board, and destroying a hopper are often performed. These fraudulent acts are often performed immediately before the gaming machine is installed in the hall of the game shop or when the game shop is closed. In rare cases, it can also occur during the operation of an amusement store. If the cheating is performed, the player will be unfair and uncomfortable, and the game shop and the manufacturer will suffer a great deal of inconvenience and damage.

  Many inventions for improving the anti-fraud function of gaming machines have been made in the past in order to prevent fraud (for example, see Patent Document 1). In the invention described in Patent Document 1, the open / close detection unit of the gaming machine has an independent power source such as a storage battery that is different from the main power supply, detects the open / close of the open / close unit, and records the number of open / closes / open / closed. According to the present invention, by supplying power to the open / close detection unit from an independent power source different from the main power source, the open / close of the open / close unit can be monitored regardless of the state of the main power source. An amusement store employee, etc., checks the recorded number of times of opening / closing and whether or not it is opened and closed afterwards, and finds fraud.

JP 2004-24409 A

  However, if an amusement store employee or the like only confirms the opening / closing record afterwards, it is not possible to sufficiently prevent an illegal act or damage caused by an illegal act performed during an amusement store operation. For example, since a conventional gaming machine can execute a game even when the opening / closing part is open, even if the player performs an illegal act such as opening and closing the opening / closing part and changing the setting value during the game, The game continues to run. In this case, the game store will not immediately notice the fraudulent act and will suffer damage due to the execution of the fraudulent game.

  The present invention has been made in view of such problems, and a gaming machine that makes it impossible to execute a game in a state where the opening / closing portion is opened while continuously monitoring the opening / closing portion of the gaming machine. The purpose is to provide.

In order to achieve such an object, the invention according to claim 1 is capable of executing a game, a housing having an opening, an opening / closing portion attached to the housing and capable of opening and closing the opening. It is possible to operate in a normal power mode and a power saving mode in which power consumption is lower than that in the normal power mode and in which a game cannot be executed. Kawawa Ri, and, upon closure of the opening portion in the power saving mode, when the power from the primary power supply apparatus is determined to have been supplied, instead of the power-saving mode to the normal power mode, the main power supply And a control means for maintaining the power saving mode when it is determined that power is not supplied from the game machine.

  According to the present invention, since the control means of the gaming machine is switched to the power saving mode when the opening / closing part is opened during operation in the normal power mode, the opening / closing part continuously monitors the opening / closing of the opening / closing part. In the open state, the game can be made impossible to execute.

  According to the present invention, since the control means of the gaming machine is switched to the power saving mode when the opening / closing part is opened during operation in the normal power mode, the opening / closing part continuously monitors the opening / closing of the opening / closing part. In the open state, the game can be made impossible to execute.

And enhance the production effect.

(Control circuit configuration)
FIG. 3 is a block diagram showing an example of the overall configuration of the control circuit of the gaming machine 1.

  The input interface of the main control board 4 detects medals that have passed through the MAX bet button 19, 1 bet button 20, start lever 21, stop button 22, settlement button 23, reset switch 25, hopper unit 7, and medal selector 12. The medal detection sensor 26, the door opening / closing sensor 60, and the like are connected.

  A motor drive circuit (not shown) of the rotary reel unit 6 and the sub control board 5 are connected to the output interface of the main control board 4.

  When the start signal is input from the start lever 21, the main control board 4 draws a lottery based on the numerical data update data and sends a control command based on the lottery result to the rotary reel unit 6 for each rotation. While individually controlling the motor of the reel 61, an effect command is transmitted to the sub-control board 5. The main control board 4 monitors the opening / closing of the door 3 based on the door signal transmitted from the door opening / closing sensor 60. The main control board 4 transmits the game information and a signal notifying that the door has been opened / closed to the hall computer 70 via the external connection terminal board 44.

  The input interface of the sub control board 5 is connected to the output interface of the main control board 4, the fraud confirmation operation switch 14, the game information display operation switch 16, and the door opening / closing sensor 60. An image display unit 9, a speaker 11, and a lamp 27 are connected to the output interface of the sub control board 5 via the relay board 10.

  The sub-control board 5 displays characters, images, etc. on the liquid crystal display 91 of the image display unit 9 according to the game situation of the gaming machine 1 based on the effect command transmitted from the main control board 4 or the lamp 27. Is turned on, or voice, music, etc. are output to the speaker 11 for effect display. Further, the sub control board 5 monitors the opening / closing of the door 3 based on the door signal transmitted from the door opening / closing sensor 60.

  The door opening / closing sensor 60 transmits a door signal to the main control board 4 and the sub control board 5. FIG. 4 shows an example of a door signal output from the door opening / closing sensor 60. The horizontal direction indicates time, and the vertical direction indicates signal level. As shown in the figure, the falling part of the door signal is an open signal, and the rising part is a closed signal. The open signal is output when the door 3 is opened, and the close signal is output when the door 3 is closed.

  5 and 6 are block diagrams showing in detail the configurations of the main control board 4, the sub control board 5, and the image display unit 9. FIG. In addition, the arrow in a figure has shown the flow of electric power in FIG. 5, and the flow of a signal in FIG.

  In a state where the gaming machine 1 is connected to an external power source and the power switch 8a is turned on, power is controlled from the main power supply device 8 through the power supply control units 48 and 58 as shown in FIG. It is supplied to the substrate 4 and the sub control substrate 5. On the other hand, when the gaming machine 1 is not connected to an external power source or power is not supplied from the main power supply device 8 because the power switch 8a is off, it is connected to the power supply control units 48 and 58. Electric power is supplied from the backup power supplies 45 and 55. That is, power is supplied from the backup power supplies 45 and 55 instead of the main power supply device 8 during the period when the gaming machine 1 is transported from the manufacturing factory to the amusement shop or outside the business hours of the amusement shop. Storage batteries such as lithium ion secondary batteries and nickel metal hydride storage batteries are used for the backup power supplies 45 and 55. The power supply control units 48 and 58 for switching between the main power supply device 8 and the backup power supplies 45 and 55 may apply a known technique related to power supply switching. For example, a known power supply switching IC can be applied.

  Further, as shown in FIG. 6, when the gaming machine 1 is connected to an external power source and the power switch 8a is turned on, the main power signal from the main power device 8 is transmitted to the main control board 4 and It is output to the sub control board 5. Further, a door signal from the door opening / closing sensor 60 is output to the main control board 4 and the sub control board 5. Then, game information created on the main control board 4 and a signal for notifying door opening / closing are output to the hall computer 70 via the external connection terminal board 44. In addition, game information, production information, and door opening / closing history information created by the sub-control board 5 are output to the image display unit 9, and game information and door opening / closing history information are provided via the external connection terminal board 54. The data is output to the computer 70.

  The sub control board 5 includes a CPU (Central Processing Unit) (hereinafter also referred to as “sub CPU”) 52, a ROM (Read Only Memory) 51, an SRAM (Static Random Access Memory) 53, a switching circuit 56, a clock module 57, and a power supply. A control unit 58, a clock generator 59, and a backup power source 55 are provided.

  The switching circuit 56 includes a multivibrator element 56a and a CR circuit 56b, and receives a door signal output from the door opening / closing sensor 60. When the switching circuit 56 receives an open signal or a close signal from the door opening / closing sensor 60, the CR circuit 56b is discharged, whereby the multivibrator element 56a outputs a start signal (output pulse) for a predetermined time (for example, several μsec). Output to.

  The clock generator 59 includes two oscillation circuits (OSC: oscillator) of a high-speed oscillation circuit and a low-speed oscillation circuit, and a switching control unit that controls the operation of the two oscillation circuits. The high-speed oscillation circuit outputs a clock frequency of about 33 MHz, for example. The low-speed oscillation circuit outputs a clock frequency of about 33 kHz, for example.

  The clock generator 59 outputs a high-speed or low-speed clock frequency to the CPU 52 depending on whether the current mode is the active mode (normal power mode) or the sleep mode (power saving mode). That is, when the CPU 52 is in the active mode, the clock generator 59 outputs the clock frequency oscillated from the high-speed oscillation circuit to the CPU 52. On the other hand, when the CPU 52 is in the sleep mode, the operation of the high speed oscillation circuit stops, and the clock generator 59 outputs the clock frequency oscillated from the low speed oscillation circuit to the CPU 52. As a result, when in the sleep mode, the CPU 52 monitors the opening and closing of the door 3 and operates with the clock frequency lowered to such an extent that the necessary power consumption can be obtained because the information in the SRAM 53 is retained. . For this reason, power consumption can be saved when in the sleep mode. On the other hand, when in the active mode, the CPU 52 operates at a clock frequency that is high enough to execute the game, and the power consumption increases.

  The clock generator 59 is not limited to the above configuration, and may have any configuration as long as it can selectively output high and low frequencies.

  The clock module 57 is configured to include, for example, a crystal oscillator and measures the date and time.

  The ROM 51 is a read-only memory. The ROM 51 stores various programs and data for performing game effects, door opening / closing monitoring processing, and the like since the game machine 1 is manufactured. The SRAM 53 is a readable / writable memory. The SRAM 53 stores various data generated during the process execution by the CPU 52.

  The CPU 52 (corresponding to “control means”) performs presentation control, determination of door opening / closing based on the activation signal output from the switching circuit 56, and switching between the active mode and the sleep mode according to the program and data stored in the ROM 51. Control, storage of the opening / closing date and time of the door 3 in the SRAM 53, and the like are performed. Regarding the determination of the door opening / closing, the CPU 52 refers to the door signal after receiving the activation signal, and in this embodiment, determines that the door 3 is opened because the door signal is Low, and the door signal is High. It is determined that the door 3 is closed. As for switching control between the active mode and the sleep mode, the CPU 52 switches to the sleep mode by receiving the clock frequency of the low-speed oscillation circuit from the clock generator 59 when the door 3 is opened, and the door 3 is closed. In this case, the active mode is switched by receiving the clock frequency of the high-speed oscillation circuit from the clock generator 59.

  The image display unit 9 includes a liquid crystal display 91, a CPU, a ROM, and a VDP (Video Display Processor), and performs display control of characters, images, and the like based on control signals from the sub-control board 5. For example, the image display unit 9 receives the history information of the door opening / closing date and time stored in the SRAM 53 when the fraud confirmation operation switch 14 is operated, and the CPU of the image display unit 9 stores the history information. Displayed on the liquid crystal display 91.

  Next, the configuration of the main control board 4 will be described. The configuration of the main control board 4 is different from the configuration of the sub control board 5 in that the sub control board 5 includes the clock module 57, whereas the main control board 4 does not include the sub control board 5. 5 ROM 51 stores programs and data for effect control, whereas ROM 41 of main control board 4 stores programs for game control (operation control of rotating reel 61, role lottery, etc.) This is the point where data is stored. Except for these points, the main control board 4 has the same structure as the sub control board 5 with regard to the configuration relating to the monitoring control of the door opening / closing.

  The hall computer 70 accumulates information received from the main control board 4 and the sub control board 5. The hall computer 70 is provided with a clock module (not shown), and acquires and stores the date and time from the clock module when receiving a signal for notification of door opening / closing from the main control board 4.

(First fraud monitoring process)
Next, the first fraud monitoring process performed by the sub control board 5 will be described with reference to the flowchart shown in FIG. As an initial state of processing, an example will be described in which power is supplied from the main power supply device 8 and the CPU 52 of the sub control board 5 is operating in the active mode.

  First, the CPU 52 monitors a signal transmitted as an interrupt signal from the door opening / closing sensor 60 via the switching circuit 56 (step S101).

  As a result of monitoring, an activation signal is detected (step S102; Yes), and if it is determined that the door 3 has been opened by confirmation of the door signal (step S103; Yes), the CPU 52 performs a power interruption process (step S105). Specifically, information being processed (hereinafter referred to as “sub CPU information”) stored in the SRAM 53 and the register of the CPU 52 is saved in the backup area of the SRAM 53.

  Next, the CPU 52 acquires the current date and time from the clock module 57, and stores the current date and time as history information in the SRAM 53 (step S106).

  Next, the CPU 52 shifts to the sleep mode by receiving the supply of the clock frequency of the low-speed oscillation circuit from the clock generator 59 (step S107), and ends the processing. As described above, when the door 3 is opened, the CPU 52 shifts from the active mode to the sleep mode. For example, when the player opens the door 3 of the gaming machine 1 while the game shop is in operation, the game is started or continued. Thus, it is possible to prevent the player from performing an illegal game and causing damage to the game store.

  Next, as a result of monitoring, an activation signal is detected (step S102; Yes), and when it is determined that the door 3 is closed (step S103; No), the CPU 52 performs an activation process (step S108). Next, the CPU 52 acquires the current date and time from the clock module 57, and stores the current date and time as history information in the SRAM 53 (step S109).

  Next, the CPU 52 checks the main power signal (step S110). As a result, when it is determined that power is supplied from the main power supply device 8 (step S111; Yes), the CPU 52 performs a transition process to the normal game mode (step S112). Specifically, the game can be started by performing initial settings of the CPU 52 and the SRAM 53 (when power interruption processing is performed in step S105, processing for restoring the saved sub CPU information is performed). Transition to the state. In this way, even if the door 3 is opened and the sleep mode is set, the door 3 is closed to return to the active mode. For example, when the employee opens and closes the door 3 during a game shop operation, the active mode is set. It can be prevented that it cannot be restored. In addition, since the transition to the normal game mode is performed after returning to the active mode, for example, when the door 3 is opened and closed for a purpose other than fraud, it is possible to prevent the game from being unrecoverable while being interrupted. it can.

  On the other hand, when it is determined that power is not supplied from the main power supply device 8 (step S111; No), the CPU 52 shifts to the sleep mode (step S107) and ends the process. If it is determined No in step S111 (that is, it is determined that there is no power supply from the main power supply device 8), the person opens the door 3, turns off the power switch 8a, and closes the door 3. Is the case.

  The above is the first fraud monitoring process. In the first fraud monitoring process, the date / time is stored in both step S106 and step S109 (that is, the date / time is stored both when the door 3 is opened and closed). It is not always necessary to store the date and time in both steps, and the date and time may be stored only in step S109 (that is, only when the door 3 is closed). Alternatively, the date and time may be stored only in step S106.

(Second fraud monitoring process)
Next, the second fraud monitoring process performed by the sub control board 5 will be described with reference to the flowchart shown in FIG. An example will be described in which power is supplied from the main power supply device 8 and the CPU 52 of the sub control board 5 is operating in the active mode.

  First, the CPU 52 monitors a signal transmitted as an interrupt signal from the door opening / closing sensor 60 via the switching circuit 56 (step S201).

  As a result of monitoring, an activation signal is detected (step S202; Yes), and when it is determined that the door 3 has been opened (step S203; Yes), the CPU 52 performs a power interruption process (step S205). Specifically, the sub CPU information being processed that is stored in the SRAM 53 and the register of the CPU 52 is saved in the backup area of the SRAM 53.

  Next, the CPU 52 shifts to the sleep mode by receiving the supply of the clock frequency of the low-speed oscillation circuit from the clock generator 59 (step S207), and ends the processing. As described above, when the door 3 is opened, the CPU 52 shifts from the active mode to the sleep mode. For example, when the player opens the door 3 of the gaming machine 1 while the game shop is in operation, the game is started or continued. Thus, it is possible to prevent the player from performing an illegal game and causing damage to the game store.

  Next, as a result of monitoring, an activation signal is detected (step S202; Yes), and when it is determined that the door 3 is closed (step S203; No), the CPU 52 performs activation processing (step S208).

  Next, the CPU 52 checks the main power signal (step S210). As a result, when it is determined that power is supplied from the main power supply device 8 (step S211; Yes), the CPU 52 performs a transition process to the normal game mode (step S212). Specifically, the game can be started by performing initial settings of the CPU 52 and the SRAM 53 (when power interruption processing is performed in step S205, processing for restoring the saved sub CPU information is performed). Transition to the state. In this way, even if the door 3 is opened and the sleep mode is set, the door 3 is closed to return to the active mode. For example, when the employee opens and closes the door 3 during a game shop operation, the active mode is set. It can be prevented that it cannot be restored. In addition, since the transition to the normal game mode is performed after returning to the active mode, for example, when the door 3 is opened and closed for a purpose other than fraud, it is possible to prevent the game from being unrecoverable while being interrupted. it can.

  On the other hand, if it is determined that power is not supplied from the main power supply device 8 (step S211; No), the CPU 52 acquires the current date and time from the clock module 57 and stores the current date and time as history information in the SRAM 53 (step S21). S213). Then, the CPU 52 shifts to the sleep mode (step S207) and ends the process. If it is determined No in step S211 (that is, it is determined that there is no power supply from the main power supply device 8), the person opens the door 3 and turns on the power as in the first fraud monitoring process. The case where the door 3 is closed by turning off the switch 8a can be mentioned.

  The above is the second fraud monitoring process. The difference between the second fraud monitoring process and the first fraud monitoring process is that when the door 3 is opened and when the door 3 is closed when power is supplied from the main power supply device 8, The date and time is stored only when the door 3 is closed when no power is supplied from the main power supply 8 without storing the date and time. As a result, the date and time when the door 3 was opened and closed during the operation of the amusement store is not stored, so the employee of the amusement store can only know the date and time when the door 3 was closed while the gaming machine 1 was being transported or the amusement store was closed. It can be confirmed by history information, and it becomes easy to find fraud.

  In the first fraud monitoring process and the second fraud monitoring process described above, the fraud monitoring process performed by the sub-control board 5 has been described, but the main control board 4 also performs the same fraud monitoring process as the sub-control board 5. Do. However, the main control board 4 does not store the date and time and transmits to the hall computer 70 that the door has been opened and closed. When the hall computer 70 receives this signal from the main control board 4, the hall computer 70 stores the received date and time.

  As described above, the CPUs 42 and 52 of the gaming machine 1 operate in the sleep mode when the door 3 is opened (step S107 in FIG. 7 and step S207 in FIG. 8), and when the door 3 is closed. In order to return to the active mode (step S108 in FIG. 7 and step S208 in FIG. 8), while the door 3 of the gaming machine 1 is continuously monitored in the sleep mode or the active mode, the game is played when the door 3 is opened. Can be made impossible. That is, while the door 3 is open, the operation of the start lever 21 and the stop button 22 is not accepted, and nothing is displayed on the image display unit 9. Therefore, it is possible to prevent a player who opened the door 3 during the operation of the amusement store while trying to perform an illegal act from starting or continuing the game, and the illegal operation is executed and the amusement store suffers damage. Can be prevented. Since the CPUs 42 and 52 monitor the opening and closing of the door 3 in the sleep mode while the door 3 is open, the CPU 42 and 52 can detect that the door 3 is closed and return to the active mode.

  In addition, since the gaming machine 1 includes backup power sources 45 and 55 that supply power when power is not supplied from the main power supply device 8, the gaming machine 1 is not connected to an external power source during transportation. The opening and closing of the door 3 can be monitored even when the power switch of the gaming machine 1 is turned off, for example, when the game store is closed. When there is no supply of power from the main power supply device 8, the CPUs 42 and 52 operate in the sleep mode, so that the backup power sources 45 and 55 can be made longer and monitoring can be continued for a long time.

  In addition, the gaming machine 1 is in a sleep mode when the door 3 is opened, and in addition to preventing illegal games from being played, in addition to creating history information on the opening and closing date and time of the door 3, Or the like can confirm whether or not there has been an illegal act by looking at the history information.

(Modification)
Although the embodiment of the present invention has been described above, the following various modifications and changes can be made to the present embodiment without departing from the gist of the present invention.
(1) In the above-described embodiment, the backup power sources 45 and 55 are described as storage batteries. However, the present invention is not limited to this, and may be, for example, a primary battery such as a manganese dry battery or an alkaline dry battery. A capacitor may also be used.
(2) In the above-described embodiment, switching between the active mode and the sleep mode is controlled by switching the clock frequency.
