In this embodiment, the case where the payout control board is provided separately from the main control board will be described, but the payout control board is configured integrally with the main control board, and the function of the payout control board is It may be incorporated in the main control board.

  The power supply unit 30 converts an AC voltage supplied from an external power source into various DC voltages and supplies power to each unit. As shown in FIG. 2, a power switch 31, a setting switch 32, and a setting key switch 33 are provided on the front surface of the casing of the power supply unit 30. The power switch 31 is used to switch the power supply unit 30 between an on state and an off state. When the power switch 31 is turned on, the power supply unit 30 is turned on, power is supplied from the power supply unit 30 to each unit, and the swivel game machine starts its operation. Specifically, power supply from the power supply unit 30 to each unit is performed via the main control board 60.

  Normally, in a spinning-type game machine, it is possible to set the payout rate to one of six levels. The setting switch 32 is a switch for instructing to set the payout rate. The setting key switch 33 is a switch for enabling the setting switch 32 to be operated. The setting key switch 33 is provided with a key hole. When the setting key is inserted into the key hole and the setting key switch 33 is turned in a predetermined direction, the setting key switch 33 can be turned on. The game play rate is set when the power is turned on. Specifically, when setting the payout rate, a game attendant inserts a setting key into the keyhole of the setting key switch 33, turns the setting key switch 33 in a predetermined direction, and then turns on the power switch 31. . Then, the main control board 60 starts the setting process of the payout rate, and displays the current setting value of the payout rate on a setting content display unit (not shown). When the attendant at the game hall operates the setting switch 32 to change the setting value of the payout rate, the main control board 60 recognizes the changed setting value and displays it on the setting content display unit.

  Various sensors 41, 42, 43, 44, 45 provided in the machine frame 1 detect information necessary for recognizing the occurrence of a predetermined event in the gaming machine. Detection signals from these sensors 41, 42, 43, 44, 45 are individually output to the main control board 60.

  Specifically, the door opening detection sensor 41 detects that the door 2 has been opened. From the detection signal from the door opening detection sensor 41, the main control board 60 can recognize the event that the door 2 has been opened. As the door opening detection sensor 41, a limit switch or the like having a function of opening and closing an electric circuit by a mechanical operation is used. The setting key switch operation detection sensor 42 detects that the setting key switch 33 is turned on. Based on the detection signal from the setting key switch operation detection sensor 42, the main control board 60 changes or confirms the event that the setting key switch 33 is turned on, that is, the setting of the gaming machine (setting of the play rate). Recognize that the work has been done.

  The inserted medal detection sensor 43 detects that a medal has been inserted from the medal slot 13. Based on the detection signal from the inserted medal detection sensor 43, the main control board 60 can recognize an event that a medal has been inserted. By the way, normally, the spinning-reel game machine has a function of determining whether fraud has been performed when a medal is inserted based on a detection signal from the inserted medal detection sensor 43. For this reason, based on the detection signal from the inserted medal detection sensor 43, the main control board 60 can also recognize that a medal insertion error has occurred, that is, an event that fraud has been performed at the time of medal insertion. The hopper motor drive detection sensor 44 detects that a signal for driving the hopper motor (a hopper motor drive signal) is generated. From the detection signal from the hopper motor drive detection sensor 44, the main control board 60 can recognize an event that a medal has been paid out. In particular, when the detection signal from the hopper motor drive detection sensor 44 is received even though the regular winning medal payout process is not performed, the main control board 60 indicates that a medal payout error has occurred, that is, a medal. It is possible to recognize an event that fraud has been performed at the time of payout. The power ON detection sensor 45 detects that the power switch 31 is turned on. From the detection signal from the power ON detection sensor 45, the main control board 60 can recognize the event that the power switch 31 is turned on.

  As described above, the detection signals from the inserted medal detection sensor 43 and the hopper motor drive detection sensor 44 are also used for recognizing that fraud has been performed in the gaming machine. In addition, as described above, opening the door 2, setting the key switch 33 to ON, and turning the power switch 31 on are actions related to setting the payout rate. For this reason, for example, if these actions are performed without any reason, it can be determined that fraud has been performed. Accordingly, the detection signals from the door opening detection sensor 41, the setting key switch operation detection sensor 42, and the power ON detection sensor 45 are similar to the detection signals from the insertion medal detection sensor 43 and the hopper motor drive detection sensor 44 in the gaming machine. It can be used to recognize that fraud has been done.

  The door opening / closing detection sensor 51 detects that the door 2 is opened and closed. A detection signal from the door opening / closing detection sensor 51 is output to the external terminal board 80 via the main control board 60. Here, the detection signal is not sent to the CPU of the main control board 60 but is simply sent to the external terminal board 80 via the main control board 60. The door opening / closing detection sensor 51 is different from the door opening detection sensor 41 in that the output destination of the signal is not the main control board 60 but the external terminal board 80, and a self-generating switch is used as the door opening / closing detection sensor 51. It is a point. In general, a self-generating switch is one that can generate electric power by using electromagnetic induction or the piezoelectric effect by mechanical operation of a movable part without supplying electric power from an external power source, and output an electric signal. Say. In the present embodiment, a self-power generation switch using electromagnetic induction is used. FIG. 4 is a schematic perspective view of the self-generating switch used in the first embodiment, and FIG. 5 is a diagram for explaining the waveform of an electric signal output from the self-generating switch. As shown in FIG. 4, the self-generating switch 500 includes a main body portion 501 and a push button (movable portion) 502 provided on the upper surface of the main body portion 501. The size of the main body 501 is about 20 mm in length, about 16 mm in width, and about 12 mm in height. The stroke of the push button 502 is about 2.5 mm. A state in which no force is applied to the push button 502 is an off state of the self-generating switch 500. When a force is applied to the push button 502 to push the push button 502 downward, the self-generating switch 500 is turned on. Then, when the force that pushes the push button 502 is released when the self-generating switch 500 is in the on state, the push button 502 automatically returns to the original position, and the self-generating switch 500 is turned off. The self-generating switch 500 as the door opening / closing detection sensor 51 is provided such that the push button 502 is mechanically operated by opening / closing the door 2. That is, when the door 2 is closed, the push button 502 is pushed in by the door 2 and the self-generating switch 500 is turned on. On the other hand, when the door 2 is opened, the push button 502 is returned to the original state. The self-generating switch 500 is turned off. Thus, when the on / off state of the self-generating switch 500 is switched by the mechanical operation of the push button 502 based on the opening / closing of the door 2, an induced electromotive force is generated, whereby the self-generating switch 500 generates power. Do. Here, electrical signals having different polarities are output when the self-generating switch 500 is switched from the on state to the off state and when the self power generation switch 500 is switched from the off state to the on state. Specifically, as shown in FIG. 5, when the self-generating switch 500 is switched from the on-state to the off-state, an electrical signal having a positive polarity is output, and when the self-generating switch 500 is switched from the off-state to the on-state. An electrical signal with a negative polarity is output at The waveform of the electric signal (pulse signal) output from the self-generating switch 500 has a width of about 3 ms and a size of about 4V.

  The main control board attachment / detachment detection sensor 52 detects that the main control board 60 has been removed and attached. A detection signal from the main control board attachment / detachment detection sensor 52 is output to the external terminal board 80. As the main control board attachment / detachment detection sensor 52, as with the door opening / closing detection sensor 51, a self-generating switch 500 shown in FIG. 4 is used. The self-generating switch 500 serving as the main control board attachment / detachment detection sensor 52 is provided such that the push button 502 is mechanically operated when the main control board 60 is attached / detached. That is, when the main control board 60 is attached to a predetermined location in the machine casing 1, the push button 502 is pushed in by the main control board 60, and the self-generating switch 500 is turned on. When the main control board 60 is removed, the push button 502 returns to the original position, and the self-generating switch 500 is turned off. The main control board attachment / detachment detection sensor 52 generates power when the on / off state is switched, and as shown in FIG. 5, the polarity differs when switching from the on state to the off state and when switching from the off state to the on state. The electrical signal is output.

  In the spinning-type game machine, a game is performed in which the symbols displayed when the three spinning cylinders 11a, 11b, and 11c are stopped are aligned with combinations of symbols corresponding to various roles. Specifically, in order to play a game in the spinning-type game machine, the player first inserts a medal directly into the medal slot 13 or inserts a medal stored in the storage device into a stored medal insertion button. One of the actions of pressing and inserting 14 is performed. Next, the player operates the start switch 16 to rotate the spinning cylinders 11a, 11b, and 11c, and then sequentially presses the stop buttons 17a, 17b, and 17c in an arbitrary order, thereby rotating the spinning cylinders 11a, 11b, and 11c. Stop. When the rotating cylinders 11a, 11b, and 11c are stopped, any one of a plurality of types of roles is set on a preset effective line such as a horizontal effective line and an oblique effective line above, inside, and below the display window 12. If a combination of symbols corresponding to such a combination is displayed in a stopped state, the game result is a prize for the combination. If the game result is a winning combination, a predetermined number of medals corresponding to the winning combination are paid out. Here, the medals to be paid out are stored in the storage device until the number of stored medals reaches 50, and the amount exceeding the stored number is paid out from the medal payout opening 22 to the medal tray 23 by the medal discharging device 26. On the other hand, if the result of the gaming machine is not a winning combination, the medal is not paid out.

  The main control board 60 mainly controls and manages game contents and medal payout. The main control board 60 includes a ROM 61, a RAM 62, and a CPU 63, as shown in FIG. The ROM 61 stores various programs relating to game content control and the like. The RAM 62 is a working memory that temporarily stores data. The CPU 63 controls the game content by executing a program stored in the ROM 61. Specifically, the CPU 63 manages the gaming state, processes for driving / stopping each of the spinning cylinders 11a, 11b, and 11c of the spinning cylinder rotating device 11, transmitting a command signal to the sub-control board 70, and various processes to the external terminal board 80. Perform signal output processing.

  First, game state management will be described. The CPU 63 controls the transition of the gaming state based on the game result and the like. Then, the CPU 63 manages the contents of the current gaming state with data relating to the gaming state. Data relating to this gaming state is stored in the RAM 62. When the game state transitions, a game having contents corresponding to the transitioned game state is executed. In the swivel-type gaming machine of the present embodiment, as the gaming state, “normal gaming state”, “first type special character in operation”, “in combination with the first type special character operating device continuous operation device” Various game states are set, such as “in operation of the second type special character”, “in operation of the continuous action device related to the second type special character”, and “in operation of the normal character”. For example, in a game, when the symbols “7-7-7” are aligned on the active line of the display window 12, the CPU 63 determines that the game state is in operation of the accessory continuous operation device related to the first type special accessory (a large bonus). ). Then, when the game state is in operation of the accessory continuous operation device related to the first type special accessory, a large bonus game is performed in which the player can obtain the largest amount of medals. This large bonus game ends when the cumulative payout number of medals exceeds a predetermined number (for example, 450).

  Further, the CPU 63 performs a driving / stopping process for each of the spinning cylinders 11 a, 11 b, 11 c of the spinning cylinder rotating device 11. The driving process of each of the spinning cylinders 11a, 11b, and 11c is a process of starting the driving operation of the three spinning cylinders 11a, 11b, and 11c when the start switch 16 is operated on condition that a medal is inserted. is there. The stopping process of each of the spinning cylinders 11a, 11b, and 11c is a process of stopping the driving of the rotating cylinder when a certain rotating cylinder is driven and a stop button corresponding to the rotating cylinder is pressed. is there.

  Further, the CPU 63 performs processing for transmitting a command signal to the sub-control board 70. There are many types of command signals transmitted from the CPU 63 to the sub control board 70. For example, there are a command signal related to game effects, a command signal indicating that a predetermined operation is performed by the player, a command signal indicating the current gaming state, and the like. The CPU 63 transmits these command signals to the sub-control board 70 to transmit various information to the sub-control board 70 to control the sub-control board 70.

  Next, output processing of various signals to the external terminal board 80 performed by the CPU 63 will be described. As shown in FIG. 3, the rotating type gaming machine is connected to an external management device 200 via an external terminal board 80. The CPU 63 of the main control board 60 transmits these signals to the external management device 200 by outputting various signals to the external terminal board 80. The external management device 200 is, for example, a hall computer that receives information from a plurality of gaming machines set in a gaming hall and manages information about each gaming machine. Signals that the CPU 63 outputs to the external terminal board 80 include a gaming state signal, a medal insertion signal, a medal payout signal, and a gaming machine signal.

  When the game state changes to various specific game states, the CPU 63 generates a game state signal indicating that the game state is the changed specific game state, and individually generates each of the generated game state signals. Output to the external terminal board 80. Specifically, the CPU 63 generates and outputs a first-type special agent operating signal as the gaming state signal 1 when the gaming state is in operation of the first-type special accessory, and the gaming state is the first When the accessory continuous operation device related to the seed special accessory is in operation, the game state signal 2 is generated and output as the game continuous signal operating signal related to the first type special accessory. Further, the CPU 63 generates and outputs a second-type special agent operating signal as the gaming state signal 3 when the gaming state is in operation of the second-special special item. When the accessory continuous operation device related to the accessory is in operation, the game state signal 4 is generated and output as the game continuous signal operating signal related to the second type special accessory. Further, the CPU 63 generates and outputs a normal-worker-in-operation signal as the game state signal 5 when the game state is in the normal-player operation.

  In addition, the CPU 63 generates a medal insertion signal and a medal payout signal, and outputs the generated medal insertion signal and medal payout signal individually to the external terminal board 80. Specifically, when receiving a detection signal from the inserted medal detection sensor 43, the CPU 63 generates and outputs a medal insertion signal indicating that a medal has been inserted. When receiving a detection signal from the hopper motor drive detection sensor 44, the CPU 63 generates and outputs a medal payout signal indicating that a predetermined number of medals have been paid out based on the detection signal.

  Further, when the CPU 63 determines that a predetermined event has occurred in the gaming machine based on the detection signals from the sensors 41, 42, 43, 44, 45, a gaming machine signal indicating that the event has occurred. At the same time, the generated game machine signals are individually output to the external terminal board 80. Specifically, when the CPU 63 receives the detection signal from the door opening detection sensor 41, the CPU 63 determines that the door 2 has been opened, and generates a door opening signal indicating that the door 2 has been opened as the gaming machine signal 1. And output. When the CPU 63 receives the detection signal from the setting key switch operation detection sensor 42, the CPU 63 determines that the setting key switch 33 is turned on, and that the setting key switch 33 is turned on as the gaming machine signal 2. A setting change signal is generated and output. When the CPU 63 determines that a medal insertion error has occurred based on the detection signal from the insertion medal detection sensor 43, the CPU 63 generates and outputs a insertion error signal indicating that a medal insertion error has occurred as the gaming machine signal 3. . Further, the CPU 63 determines that a medal payout error has occurred when receiving a detection signal from the hopper motor drive detection sensor 44 even though the regular payout medal payout process has not been performed, and the gaming machine As a signal 4, a payout error signal indicating that a medal payout error has occurred is generated and output. Further, when the CPU 63 receives the detection signal from the power ON detection sensor 45, the CPU 63 determines that the power switch 31 is turned on, and indicates that the power switch 31 is turned on as the gaming machine signal 5. Is generated and output. As described above, the CPU 63 individually outputs a total of 12 signals of the gaming state signals 1 to 5, the medal insertion signal, the medal payout signal, and the gaming machine signals 1 to 5 to the external terminal board 80.

  The sub-control board 70 mainly controls effects accompanying the progress of the game. Although not shown, the sub control board 70 includes a ROM, a RAM, a CPU, and a speaker driving circuit. Various programs relating to game effects and the like are stored in the ROM of the sub-control board 70. The RAM of the sub control board 70 is a working memory that temporarily stores data. For example, a command signal sent from the main control board 60 is temporarily stored in the RAM. Based on the command signal sent from the main control board 60, the CPU of the sub control board 70 determines the contents of the effect to be executed by the speaker 28 as effect means, and the speaker via the speaker drive circuit according to the determined contents. 28 is controlled.

  As shown in FIG. 2, the external terminal board 80 is attached to the upper part in the machine casing 1. Various signals and power are sent to the external terminal board 80 from the main control board 60. The external terminal board 80 relays the signal sent from the main control board 60 and sends it to the external management device 200. In addition, an electrical signal (detection signal) from the door open / close detection sensor 51 and an electrical signal (detection signal) from the main control board attachment / detachment detection sensor 52 are individually sent to the external terminal plate 80. Are relayed and transmitted to the external management apparatus 200.

  As shown in FIG. 3, the external terminal board 80 includes a first connector CN11 for connecting to the main control board 60, a second connector CN12 for connecting to the door open / close detection sensor 51, and a main control board removal detection sensor. 52, a third connector CN 13 for connecting to the external control device 200, a fourth connector CN 14 for connecting to the external management device 200, a fifth connector CN 15 and a sixth connector CN 16, and two relay circuits 81 and 82.

  The first connector CN11 is connected to the connector of the main control board 60 via a transmission line. The first connector CN11 includes a terminal for individually inputting each of the gaming state signals 1 to 5, the medal insertion signal, the medal payout signal, and the gaming machine signals 1 to 5 output from the CPU 63, and the power supply unit 30. A terminal for inputting power supplied via the main control board 60 is provided. The second connector CN12 has two terminals and is connected to the door opening / closing detection sensor 51. The second connector CN12 is for inputting a detection signal output from the door opening / closing detection sensor 51. The third connector CN13 has two terminals and is connected to the main control board attachment / detachment detection sensor 52. The third connector CN13 is for inputting a detection signal output from the main control board attachment / detachment detection sensor 52.

  FIG. 6 is a schematic block diagram of the relay circuits 81 and 82 provided on the external terminal board 80 in the swivel type gaming machine of the first embodiment. When each of the two relay circuits 81 and 82 receives an electrical signal output from a predetermined self-generating switch, the relay circuit 81 changes and holds the contact open / close state based on the electrical signal, and also indicates the open / close state. The open / close signal is output.

  One relay circuit 81 is provided corresponding to the door opening / closing detection sensor 51, and changes and holds the contact open / close state according to the polarity of the electrical signal output from the door opening / closing detection sensor 51. As the relay circuit 81, a one-turn latching relay having a coil and a contact is used as shown in FIG. When the relay circuit 81 receives an electrical signal having one of positive and negative polarities from the door open / close detection sensor 51, the relay circuit 81 operates to change and hold the contact open / close state, and then from the door open / close detection sensor 51. When receiving the electrical signal of the other polarity, it operates to return the contact open / closed state to the original state and hold it. Specifically, when an electrical signal having a positive polarity is sent from the door opening / closing detection sensor 51 to the relay circuit 81, a current in a predetermined direction flows through the coil, and the relay circuit 81 has a current contact state in an open state. Change the contact state to the closed state and hold it. Thereafter, when an electrical signal having a negative polarity is sent from the door opening / closing detection sensor 51 to the relay circuit 81, a current in the reverse direction flows through the coil, and the relay circuit 81 changes the contact state to the open state and holds it. And when the electrical signal is not sent from the door opening / closing detection sensor 51, the relay circuit 81 maintains the state of a contact as it is.

  The other relay circuit 82 is provided corresponding to the main control board attachment / detachment detection sensor 52, and changes the contact open / close state according to the polarity of the electrical signal output from the main control board attachment / detachment detection sensor 52. Hold. As the relay circuit 82, a one-turn latching relay is used similarly to the relay circuit 81. When the relay circuit 82 receives an electrical signal having one of positive and negative polarities from the main control board attachment / detachment detection sensor 52, the relay circuit 82 operates to change and hold the contact open / close state, and then removes the main control board attachment / detachment. When an electrical signal of the other polarity is received from the detection sensor 52, it operates to return the contact open / closed state to the original state and hold it. Specifically, when a positive polarity electrical signal is sent from the main control board attachment / detachment detection sensor 52 to the relay circuit 82, a current in a predetermined direction flows through the coil, and the relay circuit 82 is in an open state in the current contact state. If there is, change the contact state to the closed state and hold it. Thereafter, when a negative polarity electrical signal is sent from the main control board attachment / detachment detection sensor 52 to the relay circuit 82, a reverse current flows through the coil, and the relay circuit 82 changes the contact state to the open state and holds it. To do. When no signal is sent from the main control board attachment / detachment detection sensor 52, the relay circuit 82 maintains the contact state as it is.

  The fourth connector CN14 is connected to the connector of the external management device 200 via a transmission line. The fourth connector CN14 has terminals for individually outputting game state signals 1 to 5, medal insertion signals, medal payout signals, and gaming machine signals 1 to 5, respectively. The fifth connector CN15 has two terminals and is connected to the connector of the external management device 200 via a transmission line. The fifth connector CN15 is for outputting a signal corresponding to the open / closed state of the contact in the relay circuit 81. The sixth connector CN16 has two terminals and is connected to the connector of the external management apparatus 200 via a transmission line. The sixth connector CN16 is for outputting a signal corresponding to the open / closed state of the contact in the relay circuit 82. The external management device 200 constantly sends a predetermined signal to each of the fifth connector CN15 and the sixth connector CN16 to monitor the status of the connectors CN15 and CN16.

  Next, an operation of outputting a signal from the door opening / closing detection sensor 51 and a signal from the main control board attachment / detachment detection sensor 52 to the external management device 200 in the spinning cylinder type game machine of the first embodiment will be described.

  First, a signal output operation from the door opening / closing detection sensor 51 will be described. When the door 2 is opened, the door open / close detection sensor 51 generates power by itself and outputs an electric signal having a positive polarity to the second connector CN12 of the external terminal board 80. The positive polarity electric signal output to the second connector CN12 is sent to the relay circuit 81, and the relay circuit 81 is operated to close its contact. As a result, a signal corresponding to the closed state of the contact is output from the relay circuit 81 to the external management device 200. Thereafter, when the door 2 is closed, the door opening / closing detection sensor 51 generates power by itself and outputs an electric signal having a negative polarity to the second connector CN12 of the external terminal board 80. The negative polarity electrical signal output to the second connector CN12 is sent to the relay circuit 81, and the relay circuit 81 operates to change the contact from the closed state to the open state. As a result, a signal corresponding to the open state of the contact is output from the relay circuit 81 to the external management device 200. Thus, when the external management device 200 recognizes that the door 2 has been opened based on the signal output from the relay circuit 81, the external management device 200 performs a predetermined process. For example, the external management device 200 opens the door 2 of the revolving game machine when the power of the external power supply is not supplied to the revolving game machine, such as a period outside the business hours of a game store. When it is recognized, information on the fact and the date and time is stored in the storage means, or the surveillance camera installed in the store is operated to record the state of the revolving game machine. At this time, the external management apparatus 200 may issue various warnings.

  Next, a signal output operation from the main control board removal / attachment detection sensor 52 will be described. When the main control board 60 is removed, the main control board attachment / detachment detection sensor 52 generates power by itself and outputs a positive polarity electric signal to the third connector CN13 of the external terminal board 80. The positive polarity electrical signal output to the third connector CN13 is sent to the relay circuit 82, and the relay circuit 82 operates to close the contact. As a result, a signal corresponding to the closed state of the contact is output from the relay circuit 82 to the external management device 200. Thereafter, when the main control board 60 is attached to the original location, the main control board removal / attachment detection sensor 52 generates power by itself and outputs an electric signal having a negative polarity to the third connector CN13 of the external terminal board 80. The negative polarity electrical signal output to the third connector CN13 is sent to the relay circuit 82, and the relay circuit 82 is operated to change the contact from the closed state to the open state. As a result, a signal corresponding to the open state of the contact is output from the relay circuit 82 to the external management device 200. Thus, when the external management device 200 recognizes that the main control board 60 has been removed based on the signal output from the relay circuit 82, the external management device 200, for example, when the door 2 described above is opened. The same processing as that to be performed is performed.

  In the swivel type gaming machine of the first embodiment, the door open / close detection switch (self-generating switch) outputs an electrical signal in response to the opening / closing of the door, and a relay circuit provided corresponding to the door open detection switch is provided. Based on the output electrical signal, the contact open / close state is changed and held, and the contact open / close signal indicating the open / close state is output to the external management device, so that power from the external power source is supplied to the gaming machine. It is possible to detect the opening and closing of the door even during the power-off period. In addition, the main control board desorption detection sensor (self-generating switch) outputs an electrical signal in response to the main control board desorption, and the relay circuit provided corresponding to the main control board desorption detection sensor is output. By changing and holding the contact open / closed state based on the electrical signal and outputting the contact open / close signal indicating the open / closed state to the external management device, the power supply from the external power supply is not supplied to the gaming machine Even during this period, the detachment of the main control board can be detected. Therefore, even if someone opens the door or removes the main control board for the purpose of cheating on the gaming machine, it can detect that the door has been opened or the main control board has been removed. Since this is possible, security can be improved. In particular, when the external management device detects that the door has been opened or the main control board has been removed based on the contact open / close signal output from the relay circuit, for example, various external alarms can be issued.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to the drawings.

In the second embodiment as well, the case where the gaming machine is a spinning type gaming machine will be described as in the first embodiment. In the second embodiment, the schematic perspective view of the gaming machine with the door closed and the schematic perspective view of the gaming machine with the door open are substantially the same as FIGS. 1 and 2, respectively. 1 and 2 will also be used to describe the game machine of the embodiment.

  As shown in FIGS. 1, 2, and 7, the spinning-type game machine of the second embodiment includes a spinning-rotation device 11, a display window 12, a medal slot 13, a stored medal slot button 14, A stored medal number display unit 15, a start switch 16, three stop buttons 17a, 17b, and 17c, three stoppable lamps 18a, 18b, and 18c, a stored medal clearing button 19, and a payout medal number display unit 21 , Medal payout port 22, medal tray 23, medal supply hole 24, hopper bucket 25, medal discharge device 26, payout control board 27, speaker 28, lamp 29, power supply unit 30, door An opening detection sensor 41, a setting key switch operation detection sensor 42, a throw-in medal detection sensor 43, a hopper motor drive detection sensor 44, a power ON detection sensor 45, a main switch Comprising a control substrate-replacement detecting sensor 52, a main control board 60, the sub-control board 700, and an external terminal board 800. In the description of the swivel type gaming machine of the second embodiment, in FIG. 2, the sub control board 70 is read as the sub control board 700, and the external terminal board 80 is read as the external terminal board 800.

  The difference between the first embodiment and the first embodiment is that the door opening / closing detection sensor is not provided as the self-generating switch, but only the main control board attachment / detachment detection sensor 52 is provided. The point that the signal from the main control board attachment / detachment detection sensor 52 is output not to the external terminal board 800 but to two relay circuits provided on the sub control board 700, and the sub control board 700 at a predetermined timing. The point is to check the state of the contacts in the two relay circuits. Other configurations are the same as those of the first embodiment.

  The main control board attachment / detachment detection sensor 52 detects that the main control board 60 has been removed and attached. In the second embodiment, the detection signal from the main control board attachment / detachment detection sensor 52 is output to the sub control board 700. The main control board attachment / detachment detection sensor 52 is composed of a self-generating switch, and the operation thereof is as already described in the first embodiment.

  The external terminal board 800 relays the signal sent from the main control board 60 and sends it to the external management device 200. As shown in FIG. 7, the external terminal board 800 includes a first connector CN <b> 21 for connecting to the main control board 60 and a second connector CN <b> 22 for connecting to the external management device 200. The first connector CN21 is connected to the connector of the main control board 60 via a transmission line. The first connector CN21 includes a terminal for individually inputting each of the gaming state signals 1 to 5, the medal insertion signal, the medal payout signal, and the gaming machine signals 1 to 5 output from the CPU 63, and the power supply unit 30. A terminal for inputting power supplied via the main control board 60 is provided. The second connector CN22 is connected to the connector of the external management device 200 via a transmission line. The second connector CN22 has terminals for individually outputting game state signals 1 to 5, medal insertion signals, medal payout signals, and gaming machine signals 1 to 5, respectively.

  The sub-control board 700 mainly controls effects accompanying the progress of the game. In the second embodiment, however, the sub-control board 700 further performs a process of determining whether or not there is a possibility that an illegal act has been performed on the main control board 60. . As shown in FIG. 7, the sub-control board 700 includes a ROM 710, a RAM 720, a CPU 730, a speaker drive circuit 740, a first relay circuit 750, a second relay circuit 760, and a main control board detachment detection sensor 52. And a connector CN31 for connection. The ROM 710 stores various programs related to game effects and the like. The RAM 720 is a working memory that temporarily stores data. For example, a command signal sent from the main control board 60 is temporarily stored in the RAM 720.

  FIG. 8 is a schematic block diagram of the first relay circuit 750 and the second relay circuit 760 provided on the sub-control board 700 in the swivel type gaming machine of the second embodiment. As shown in FIGS. 7 and 8, the first relay circuit 750 and the second relay circuit 760 are connected in parallel to the main control board attachment / detachment detection sensor 52. The first relay circuit 750 includes a one-turn latching relay 751 and a diode 752, and the second relay circuit 760 includes a one-turn latching relay 761 and a diode 762. Here, the one-turn latching relays 751 and 761 have coils and contacts. The diode 752 is connected between one terminal of the connector CN31 to which a signal from the main control board attachment / detachment detection sensor 52 is input and the one-turn latching relay 751, and the diode 762 is connected to the one terminal of the connector CN31 and the one-turn latching relay. The diode 752 and the diode 762 are relatively opposite in the direction of the anode and the cathode. For this reason, signals from the main control board attachment / detachment detection sensor 52 are not simultaneously output to the one-turn latching relay 751 and the one-turn latching relay 761. Here, each of the one-turn latching relay 751 and the one-turn latching relay 761 is in an open state in advance in the initial state.

  The first relay circuit 750 operates when an electrical signal having one of positive and negative polarities is sent from the main control board attachment / detachment detection sensor 52, changes the contact open / close state, and then holds the main control circuit. Even if an electrical signal having either positive or negative polarity is sent from the substrate attachment / detachment detection sensor 52, the state is maintained as it is. Specifically, when the contact state of the one-turn latching relay 751 is an open state, the main control board 60 is removed, and a signal having a positive polarity is sent from the main control board attachment / detachment detection sensor 52 to the first relay circuit 750. When sent, the signal is output to the coil of the one-turn latching relay 751 via the diode 752, and the one-turn latching relay 751 changes the contact state of the switch from the open state to the closed state and holds it. Thus, when the contact state of the one-turn latching relay 751 is closed, the main control board 60 is attached, and a negative polarity signal is sent from the main control board attachment / detachment detection sensor 52 to the first relay circuit 750. However, the signal is not output to the coil of the one-turn latching relay 751 by the rectifying action of the diode 752, and the one-turn latching relay 751 maintains the contact state in the closed state. When the contact state of the one-turn latching relay 751 is closed, the main control board 60 is removed again, and a signal of positive polarity is sent from the main control board attachment / detachment detection sensor 52 to the first relay circuit 750. Even if it is sent, the contact state of the one-turn latching relay 751 is kept closed.

  Further, the second relay circuit 760 operates when an electrical signal having the other polarity of positive and negative polarities is sent from the main control board attachment / detachment detection sensor 52 to change and hold the contact open / close state, and then Even if an electric signal of either positive or negative polarity is sent from the main control board attachment / detachment detection sensor 52, the state is maintained as it is. Specifically, when the contact state of the one-turn latching relay 761 is an open state, the main control board 60 is removed, and a signal having a positive polarity is sent from the main control board removal / attachment detection sensor 52 to the second relay circuit 760. When the signal is sent, the signal is not output to the coil of the one-turn latching relay 761 by the rectification action of the diode 762, and the one-turn latching relay 761 maintains the contact state in the open state. Thereafter, when the removed main control board 60 is attached and a signal of negative polarity is sent from the main control board removal / attachment detection sensor 52 to the second relay circuit 760, the signal is sent through the diode 762 as a one-turn latching relay. The one-turn latching relay 761 changes and maintains the contact state of the switch from the open state to the closed state. When the contact state of the one-turn latching relay 751 is thus closed, the main control board 60 is then removed again, and a signal with a positive polarity is sent from the main control board removal / attachment detection sensor 52 to the first relay circuit 750. Even if the removed main control board 60 is attached again and a negative polarity signal is sent from the main control board attachment / detachment detection sensor 52 to the first relay circuit 750, the one-turn latching relay 751 The contact state at is kept closed.

  The CPU 730 determines the contents of the effect to be executed by the speaker 28 as effect means based on the command signal sent from the main control board 60, and controls the speaker 28 via the speaker drive circuit 740 according to the determined contents. . In the second embodiment, the CPU 730 checks the contact state of the first relay circuit 750 and the second relay circuit 760 at a predetermined timing, and performs a fraudulent act determination process for the main control board 60. This process of determining whether or not there is an illegal act on the main control board 60 is executed when the power switch 31 is turned on and the supply of power from the external power supply is started. Specifically, the CPU 730 determines whether there is a possibility that an illegal act on the main control board 60 has been performed based on the contact state in the first relay circuit 750 and the contact state in the second relay circuit 760. If CPU 730 determines that there is a risk of fraud, CPU 730 outputs information indicating that to speaker 28. Thereby, for example, a predetermined alarm is issued from the speaker 28. It should be noted that the program and the circuit are configured so that the contact state in the first relay circuit 750 and the contact state in the second relay circuit 760 are both open after the above-described fraudulent act determination process.

  Next, the fraudulent act determination process performed by the CPU 730 of the sub control board 700 in the swivel type gaming machine of the second embodiment will be specifically described.

  When the power switch 31 is turned on and the supply of power from the external power supply is started, the CPU 730 of the sub control board 700 executes a predetermined initialization process. As one process in the process, a process for determining whether or not there is an illegal act on the main control board 60 is performed. Specifically, the CPU 730 checks the contact state of the first relay circuit 750 and the second relay circuit 760. There are three possible combinations of the contact state in the first relay circuit 750 and the contact state in the second relay circuit 760. That is, when the contact state in the first relay circuit 750 is open and the contact state in the second relay circuit 760 is open, the contact state in the first relay circuit 750 is closed and the second relay circuit When the contact state in 760 is an open state, the contact state in the first relay circuit 750 may be a closed state, and the contact state in the second relay circuit 760 may be a closed state. The fact that both the contact state in the first relay circuit 750 and the contact state in the second relay circuit 760 are in the open state means that the main control board 60 has not been removed, and illegal acts on the main control board 60 are not performed. It means that you are not. In addition, the contact state in the first relay circuit 750 is closed and the contact state in the second relay circuit 760 is open. This means that the main control board 60 has been removed and the current revolving game This means that the main control board 60 is not attached to a predetermined place in the machine. Further, the contact state in the first relay circuit 750 and the contact state in the second relay circuit 760 are both closed, which means that the main control board 60 has been removed and then the main control board 60 has been attached. Means that. Therefore, in this case, there is a possibility that an illegal act is performed on the main control board 60. The CPU 730 checks the contact state in the first relay circuit 750 and the contact state in the second relay circuit 760, and that at least one of the relay circuits is operated to change the contact open / close state, that is, at least one of the contact states. If it is recognized that the contact state is the closed state, it is determined that there is a possibility that an illegal act is performed on the main control board 60. Then, the CPU 730 outputs information indicating that there is a possibility that an illegal act on the main control board 60 is being performed to the speaker 28. When such information is output from the speaker 28, an attendant at the game hall checks whether the main control board 60 has been replaced or modified with respect to the revolving game machine. As a result, if the existence of an illegal act is clarified, the revolving game machine is replaced with a new revolving game machine.

  In the swivel type gaming machine of the second embodiment, the main control board removal / attachment detection sensor (self-generating switch) is the main control board even during the power shut-off period when the power from the external power source is not supplied to the gaming machine. When the control board is removed, a positive polarity electrical signal is output to the first relay circuit and the second relay circuit, and when the main control board is installed thereafter, a negative polarity electrical signal is sent to the first relay circuit and the second relay circuit. Can output to two relay circuit. The first relay circuit changes and holds the contact state from the open state to the closed state when the positive polarity electric signal is first sent, and the second relay circuit holds the negative polarity electric signal. When the signal is first sent, the contact state is changed from the open state to the closed state and held. That is, for example, when power from an external power source is not supplied to the gaming machine at night, when the door is opened and closed and the main control board is detached, the trace is left as a contact state in the two relay circuits. I can leave. For this reason, when the supply of power from the external power source to the gaming machine is started, the sub-main control board checks the contact state in the two relay circuits, and at night, the main control board in the gaming machine When it is determined that it has been removed, for example, various alarms can be issued, so that security can be improved.

I can leave.

  Furthermore, in the second embodiment described above, when the CPU of the sub control board determines that there is a risk of fraudulent acts on the main control board, a case has been described in which information indicating that fact is output to the speaker. However, in the case where the rotating type gaming machine is provided with an image display device (production means) that produces an effect relating to the game by displaying an image, the CPU of the sub-control board may perform an illegal act against the main control board. You may make it display the information which shows that there exists a possibility of having been performed on this image display apparatus.

  In each of the above embodiments, the case where the present invention is applied to a rotating game machine has been described. However, for example, the present invention may be applied to a pachinko game machine.

  By the way, in each of the above-described embodiments, the case where the present invention is applied to a gaming machine such as a swivel type gaming machine or a pachinko gaming machine has been described. However, the present invention relates to opening and closing of doors and various control boards in the gaming machine. In general, the present invention can be used as a detection device for detecting a mechanical displacement including the detachment, opening and closing of an object to be detected. That is, in this case, the present invention is a detection device for detecting a mechanical displacement including attachment / detachment, opening / closing of an object to be detected, and the mechanical displacement of the object to be detected without supplying electric power from an external power source. When a self-generating switch that generates electric power and outputs an electric signal by mechanical operation of a movable part based on the electric signal, and when receiving an electric signal output from the self-generating switch, the switching state of the contact is determined based on the electric signal. And a relay circuit that outputs a contact open / close signal indicating the open / closed state. As described above, the self-power generating switch generates electric power and outputs an electric signal when the movable part mechanically operates based on the mechanical displacement of the object to be detected, and the relay circuit based on the output electric signal. By changing and holding the contact open / closed state and outputting a contact open / close signal indicating the open / closed state, the mechanical displacement of the detected object, for example, the attachment / detachment of the detected object without supplying power from an external power source , Opening and closing can be detected. For this reason, for example, even if someone removes and replaces the object to be detected using unauthorized means, this can be detected, so that security can be improved.

  Further, in the detection device according to the present invention, the self-generating switch switches the electrical signal of one of the positive and negative polarities by the operation of the movable part based on the detachable displacement of the mechanical displacement of the detected object. And outputs an electrical signal of the other of the positive and negative polarities by the operation of the movable part based on the return displacement of the mechanical displacement of the object to be detected, When the electrical signal of the other polarity is received, it operates to change and maintain the contact open / close state, and then when the electrical signal of the other polarity is received from the self-generating switch, The open / closed state may be returned to the original state and held. As a result, the relay circuit can change and hold the contact open / closed state according to the polarity of the electrical signal output from the self-generating switch, so if the contact state in the relay circuit is monitored, for example, It can be detected that the detected object has been removed and that the detected object has been attached thereafter.

  Further, in the detection device according to the present invention, the self-generating switch switches the electrical signal of one of the positive and negative polarities by the operation of the movable part based on the detachable displacement of the mechanical displacement of the detected object. And outputs an electrical signal of the other of the positive and negative polarities by the operation of the movable part based on the return displacement of the mechanical displacement of the object to be detected, and two relay circuits are provided. One of the two relay circuits operates when the electric signal of the one polarity is sent from the self-generating switch, and changes and holds the contact open / closed state. Even if a polarity electrical signal is sent, the state is maintained as it is, and the other of the two relay circuits operates when the other polarity electrical signal is sent from the self-generating switch, And held by changing the closed state, then, it may be configured to maintain the its state even sent the positive or negative polarity electrical signals from the self-powered switch. As a result, one of the two relay circuits changes the state of the contact from, for example, an open state to a closed state when it first receives, for example, a positive polarity electrical signal from the self-generating switch, and holds it. The other of the two relay circuits can change and hold the contact state from the open state to the closed state when the negative polarity electrical signal is first received from the self-generating switch. When is displaced mechanically, a trace of the displacement can be left as a contact state in the two relay circuits. For this reason, for example, with respect to the detachable detected object, whether the detected object has never been detached, the detected object has been removed, or the detected object, based on the state of the contacts in the two relay circuits. It can be determined whether or not the device is mounted after being removed.

  In each of the above-described embodiments, the case where the self-generating switch is one that generates power using electromagnetic induction has been described. However, the present invention is not limited to this, and the self-generating switch is a machine. As long as it can generate electric power based on the target displacement, for example, it may generate electric power using the piezoelectric effect.

  Further, in each of the embodiments described above, the self-generating switch outputs a positive polarity electrical signal when switching from the on state to the off state, and outputs a negative polarity electrical signal when switching from the off state to the on state. However, the present invention is not limited to this, and the self-generating switch outputs a negative polarity electrical signal when switching from the on state to the off state, and switches from the off state to the on state. Sometimes an electrical signal having a positive polarity may be output.

  As described above, according to the detection apparatus of the present invention, it is possible to detect attachment / detachment, opening / closing, etc. of an object to be detected even when the power of the external power supply is not supplied. In addition, according to the gaming machine according to the present invention, since it is possible to monitor the risk of fraud at the time of power interruption when the power of the external power supply is not supplied, security can be improved. Therefore, the present invention is particularly suitable for use in various gaming machines such as a pachinko gaming machine and a swivel type gaming machine.
