Description

  The present invention relates to a gaming machine such as a slot machine, and more particularly to a gaming machine, a fraud detection method, and a program for preventing fraud.

  In a gaming machine such as a slot machine, a player can enjoy a game by inserting a predetermined number of medals and game media such as a game ball into the gaming machine. The game media necessary for the game can be borrowed at a game media rental machine or the like provided in the game hall, and the game can be started by putting it into the game media slot of a desired game machine.

The slot machine basically pays out medals as prizes when the patterns are complete. Whether or not the patterns are complete depends on the result of a lottery by an internal computer. Various prizes, such as big bonuses, regular bonuses, and small roles, also follow the results of internal computer lottery. The contents of the lottery process can be changed within a predetermined range, and the setting work is performed by the store in a hall where a gaming machine is installed. To change the setting, open the door of the gaming machine, turn on the power switch while turning on the setting key switch provided on the power supply unit, enter the mode where the setting can be changed, and then press the setting change switch. It was performed according to the operating procedure.

Embodiment 1 of the Invention
A slot machine and its fraud prevention method according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a front view of the slot machine with the front door closed.
FIG. 1 shows a slot machine 100. As shown in FIG. 1, the slot machine 100 includes a slot machine main body (game machine housing) 120 and a front door 130 attached to one side of the front surface of the slot machine main body 120 by a hinge or the like so as to be opened and closed. Yes. As shown in FIG. 1, a game display unit 131 is provided substantially in the center of the front door 130, and a medal insertion slot 132 for a player to insert medals is provided at the lower right corner of the game display unit 131. Provided on the further right side of the medal insertion slot 132 is a reject button 133 for forcibly discharging a clogged medal inserted from the medal insertion slot 132 to the outside of the slot machine 100.

  A start switch 134 for starting a game is provided at the lower left of the game display unit 131, and three stop buttons 140 are provided corresponding to the three reels. A medal payout port 135 is provided at the center of the lower end of the front door. When a game medal is inserted into the medal slot 132 or when the start switch 134 is operated on condition that the bet switch 137 is operated, the three reels start to rotate and the game starts. A cancel switch (also referred to as a cancel button) 138 is for requesting the return of inserted medals.

  FIG. 2 is a block diagram showing an electrical schematic structure of the slot machine 100. In this figure, the display about the power supply system is omitted. The slot machine 100 includes a main substrate (processing unit) 1 and a sub-substrate (sub-processing unit) 2 that operates in response to a command from the main substrate (processing unit) 1.

  The main board 1 is for performing an internal lottery in response to a player's operation, and processing such as rotation / stop of a reel (rotating drum) and payout of medals. The main board 1 includes a CPU that performs a control operation according to a preset program, and ROM and RAM that are storage means.

  When the main board 1 controls the rotation and stop of the rotating reel 40 based on the operation of the start switch 134 and the stop switch 140, a lottery for determining whether or not to win based on a predetermined lottery probability. And a winning lottery means (not shown). A winning flag is established when the lottery result by the winning lottery means is a winning, and the combination of stop symbols of the rotating reel (rotating drum) 40 coincides with a predetermined winning symbol while the winning flag is established. The conditions are set so that the winning is confirmed and the player is given a medal or special game profit.

  The sub-board 2 is for receiving a command signal from the main board 1 and notifying the result of the internal lottery and performing various effects. The sub-board 2 includes a CPU that performs a control operation according to a preset program, and a ROM and a RAM that are storage means.

  The sub-board 2 receives a command signal from the main board 1 and performs processing such as effects according to the command signal. The flow of the command signal is only one from the main board 1 to the sub board 2, and conversely, no command signal or the like is output from the sub board 2 to the main board 1.

  Signals from a plurality of door opening detection sensors S-1 to S-4 are input to the main board 1 (the number is four in the example of FIG. 2 but is not limited thereto). The main board 1 determines the opening of the door based on the output signals of these sensors S-1 to S-4, and notifies that fact or performs error processing as necessary. For example, an alarm sound indicating the opening of the door is sounded or a lamp or the like is blinked. The execution of the normal game may be stopped, and this state may be held until the reset switch is operated. The main board 1 functions as a control unit that determines the opening of the door based on the outputs of the plurality of door opening detection sensors S-1 to S-4. However, the control unit may be provided separately from the main board 1. It is.

  The main board 1 includes a start switch 134, a stop switch 140, a reel (rotating cylinder) driving unit 70, a reel (rotating cylinder) position detection circuit 71, a hopper driving unit 80, a hopper 81 for storing and paying out medals, and a hopper 81. A medal detection unit 82 for counting the number of medals paid out is connected. A peripheral substrate (local substrate) such as a control substrate 200 of the liquid crystal display unit, a speaker substrate 201, and an LED substrate 202 (not shown) is connected to the sub substrate 2. Hereinafter, these peripheral boards / devices excluding the start switch 134 and the stop switch 140 will be described.

  The reel (rotating cylinder) driving unit 70 is a circuit that drives a stepping motor (not shown) that rotationally drives three reels (rotating cylinders). Each stepping motor is subjected to 1-2 phase excitation by a reel (rotating drum) drive circuit 70, and rotates once when a predetermined number of drive signals are supplied.

  The reel (rotor) position detection circuit 71 is provided in the vicinity of a reel (rotor) (not shown) and receives an output pulse signal from a photosensor (not shown) for detecting the rotational position of the reel (rotor). The rotation position of each of the three reels (rotating drums) is detected and a detection signal is output. A photosensor (not shown) detects a shielding plate (not shown) provided on each reel (rotating cylinder) and generates a reset pulse every time each reel (rotating cylinder) rotates once. This reset pulse is given to the CPU of the main board 1 via the reel (rotating cylinder) position detection circuit 71. In the RAM of the main board 1, a count value corresponding to the rotation position within one rotation range is stored for each reel (rotating cylinder), and when the CPU receives a reset pulse, the CPU forms this count formed in the RAM. The count value is cleared to “0”. By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor is eliminated every rotation.

  The hopper driving unit 80 is a circuit that drives a motor (not shown) of the hopper 81 that stores medals and pays out the designated number of medals.

  The medal detection unit 82 is for counting the number of medals paid out from the hopper 81. When the medal count value actually paid out received from the medal detection unit 82 reaches the predetermined payout number data, the CPU of the main board 1 stops the driving by the hopper driving unit 80 and ends the medal payout. . The hopper drive circuit 80 and the medal detection unit 82 pay out a predetermined number of medals to the player based on the game result.

The liquid crystal control board 200 is a circuit for driving a liquid crystal display unit (not shown).
The speaker board 201 is a circuit for driving a loudspeaker (not shown).
The LED substrate 202 is a circuit for driving a display lamp and a back lamp (not shown).

  The ROM of the main board 1 stores game processing procedures executed in the slot machine 100 as a sequence program, as well as a winning probability table, a symbol (symbol) table, a winning symbol combination table, and the like. Has been stored. The winning probability table is divided so as to divide the extracted random number into each winning mode, and stores data for dividing a certain range of generated random numbers into each winning mode. In other words, the winning probability table has an area divided for each winning mode corresponding to all possible random number areas. For example, a range of 0 to a certain number is divided into a plurality, one division (area) is excluded, and the other division (area) is set as winning 1, winning 2,. The extracted random number data is collated with each of the winning determination area data divided for each winning mode in the entire random number area, and the winning corresponding to the winning mode to which the extracted random number data belongs is determined. For example, it is determined to which category (region) of the winning probability table the extracted random number value belongs, and if the category is, for example, a category of winning 1, it is determined as “winning 1”. Similarly, if the extracted random number value belongs to an out-of-range category (region) in the winning determination table, it is determined as “out”. For example, when the evaluation of the lottery process is out of place, the predetermined symbols are set so as not to be aligned (so-called kicking), and when winning, the predetermined symbols are aligned on condition that the stop switch 134 is pressed at a predetermined timing. (So-called pull-in). And if predetermined symbols are prepared, medals corresponding to winning symbols are paid out. Since various types of winning are generated with the probability according to the data setting of the winning probability table, for example, the total medal within the business hours of the day is not influenced by the skill of the player. The payment rate is kept almost constant.

  FIG. 3 is a perspective view showing a state in which the front door 130 of the slot machine main body (game machine housing) 120 is opened. In the example of FIG. 3, the front door 130 is composed of an upper portion 130-1 and a lower portion 130-2, and the upper portion 130-1 and the lower portion 130-2 are independently formed. Indicates the front door that can be opened and closed. FIG. 3 shows a state in which both of them are opened. First rails 150a and 150b are provided at the right end of the slot machine main body 120 (the end opposite to the hinge of the front door) along the vertical direction. On the other hand, at the left end (the end opposite to the hinge of the front door) of the upper part 130-1 and the lower part 130-2 of the front door 130 so as to correspond to them with the front door 130 closed. Second rails 151a and 151b are provided along the vertical direction. In other words, the first rails 150a and 150b are provided around the opening of the slot machine main body 120 toward the front door 130, and the second rails 151a and 151b are provided around the front door 130 of the slot machine main body 120. It is provided for the inside.

  Opening detection of the front door portions 130-1 and 130-2 is possible regardless of where the sensors are attached on the first rails 150a and 150b and the second rails 151a and 151b. Typically, as shown in FIG. 3, a flat plate, an L-shaped section, a U-shaped section, or a C-shaped section angle is attached to the right inner side of the front door 130 and the opening right end of the slot machine body 120. At this time, with the front door 130-1 closed, the first rail 150a and the second rail 151a are arranged close to each other and parallel to each other. If arranged in this way, even if the sensor S is moved to an arbitrary position on the rail, the detection sensitivity and the like can always be kept the same. The same applies to the front door 130-2. When the movement range of the sensor is limited, it is only necessary to detect the opening of the door at least at an arbitrary position within the range. As shown in FIG. 3, the front doors 130-1 and 130- There is no need to provide rails over the entire range of two.

  Further, as shown by the dotted line in FIG. 3, the second rails 151c and 151d are provided substantially horizontally at the upper end (or lower end) of the upper portion 130-1 and the lower portion 130-2 of the front door 130, Correspondingly, the first rails 150c and 150d may be provided substantially horizontally in the opening of the slot machine body 120. However, in this case, the detection sensitivity of the sensor may vary depending on the sensor mounting position (when the sensor is placed at the right end, it can be detected even when the front door 130 is slightly opened, but when the sensor is placed at the left end) Cannot be detected unless the front door 130 is opened widely). On the other hand, if the rails are provided in a substantially vertical direction (in other words, provided substantially parallel to the rotation axis of the hinge) as in the first rails 150a, 150b and the second rails 151a, 151b, The detection sensitivity can be made almost the same regardless of the mounting position. From the viewpoint of suppressing variations in detection sensitivity, a vertical arrangement such as the first rails 150a and 150b and the second rails 151a and 151b is preferable.

  The first rails 150a and 150b are provided with receiving portions S-1R to S-4R of the door open detection sensors S-1 to S-4, respectively, and the door open detection sensors S-1 to S-4R are provided to the second rails 151a and 151b. S-4 transmitters S-1T to S-4T are provided, respectively. These sensors are movably mounted on each rail (see FIG. 9). When one of the transmission unit and the reception unit is attached at an arbitrary position, the other is attached at a corresponding position. In addition, you may make it attach a transmission part and a receiving part reversely. The door opening detection sensors S-1 to S-4 in FIG. 3 include a transmitting unit that transmits a light or radio wave signal and a receiving unit that receives the signal, and the door opening is detected based on an output signal of the receiving unit. Is detected. Note that the door opening detection sensors S-1 to S-4 in FIG. 3 are merely examples, and other types of sensors can be used. For example, a mechanical switch may be used. In this case, a sensor may be provided on either the first rail 150 or the second rail 151, and only one rail is required (a specific example of the sensor will be described later).

The gaming machine according to the embodiment of the present invention includes a plurality of door opening detection sensors S-1 to S-4. These sensors are used to detect the opening (or closing) of the door and to detect fraud. There are the following three methods.
(1) Detecting the open (or closed) state of all sensors (2) Randomly selecting a plurality of sensors to be effective (detection target) (3) Monitoring the detection order of the plurality of sensors

  The above three will be described in order.

(1) Detecting the open (or closed) state of all sensors When a plurality of door opening detection sensors are monitored and the door opening or closing is detected by the coincidence of the plurality of door opening detecting sensors, the door is opened or closed. to decide. However, some of the plurality of door opening detection sensors detect the opening or closing of the door, and if the others do not agree with this, it is determined that this is an illegal action, and error processing is performed or internal setting change is not permitted. When all the sensors do not operate, it is impossible to perform an operation such as an error notification or a setting change, so that it is impossible to execute an illegal act such as a setting change with a little door open. The setting change is to change an internal setting for selecting the above-described winning probability table. A plurality of winning probability tables are prepared in advance in the ROM of the main board 1 so that it is possible to select which table is used in the hall where the gaming machine is installed. Since the probability of winning / winning varies depending on the type of table, there is an illegal act (setting change goto) in which the type of table to be used is changed to be advantageous to the user.

  The above process will be described below with reference to the flowchart of FIG. FIG. 4 is an internal setting process flowchart in the gaming machine according to the first embodiment of the present invention.

In order to change the internal setting for selecting the winning probability table, the following procedure is required.
S1: Turn off the power. Once the power is turned off and then turned on again, the control unit looks at the state of the setting switch at that time, and performs a setting change process according to the state.
S2: A setting key switch (not shown) is turned on. Normally off.

S3: A power switch (not shown) is turned on. As a result, power is supplied to the gaming machine. Since the setting key switch is on, a setting change command is output.
S4: It is determined whether a setting change command has been received. If received (YES), the process proceeds to S5. If not received (NO), the process proceeds to the normal game process of S15 without shifting to the setting change mode.

S5: When the setting change is being monitored (YES), the process proceeds to S6. When monitoring is not performed (NO), the process proceeds to S10 and immediately shifts to the setting change mode (same as the conventional gaming machine). The reason why the monitoring process is turned on / off in this way is to enable the user (hall) to select whether or not to use this monitoring function.

S6: The state of the front door is monitored. Specifically, the outputs of the door opening detection sensors S-1 to S-4 are monitored.

S7: When all the outputs of the door opening detection sensors S-1 to S-4 detect the door opening (YES), it is considered a normal operation, so the processing of S10 and after is performed to accept the setting change. If not (NO), it is considered an illegal act, so the processes of S8 and S9 are performed. Normally, when the setting is changed, the front door is opened, so that all of the sensors S-1 to S-4 should detect the opening of the door. However, the fact that some of the sensors do not detect the opening of the door is very likely to be a fraudulent act such as changing the setting with the door slightly opened.

S8: An error notification is performed. The notification of the error is performed by emitting or blinking all or a part of a lamp, LED, or liquid crystal display device (not shown) that can be controlled by the sub-board 2, or by lighting or displaying a specific pattern or not (not shown). This is performed by blowing a speaker or by arbitrarily combining notification modes. Instead of or in addition to this, an error signal may be output to the outside. This error signal is received by the hall computer, for example, and an error is displayed on the hall monitoring device.

S9: Stop receiving the game together with the error notification, and disable the normal game. For example, the CPU is not stopped until a reset signal is received, or a switch signal other than reset is not read.

S10: If the operation is normal, the mode shifts to the setting change mode. The current set value is displayed on a display unit (not shown) (for example, provided below the symbol display window).

S11: Select an internal setting. The internal setting can be set, for example, in 1 to 6 stages. When a setting switch / reset switch (not shown) is operated, the displayed setting value changes.

S12: Operate the start lever.

S13: As a result, the set value is confirmed, and the set value is stored in a storage unit (not shown).

S14: The setting key switch is turned off. The set value display on the display disappears. And S15: A normal game process is performed.

(2) Randomly select a plurality of sensors to be effective (detection target) Select a part of the plurality of door opening detection sensors, and determine whether the door is open or closed based on the output of the selected sensors. . If a sensor other than the selected sensor is operated, error processing is performed, or change of the internal setting is not permitted. In order to prevent electrical signal fraud (for example, directly grounding the sensor output signal line), for example, to force the sensor output signal to the door open detection state (or closed state) by unauthorized means. The sensor used to detect the opening (or closing) of is selected randomly, for example. When a sensor that is not used for detection operates (when a signal is output), it is determined as an error, and is regarded as an illegal act.

  A flowchart of the above process is shown in FIG. Since FIG. 5 is almost the same as FIG. 4, only the differences (S6 and S7b) will be described.

S6: The state of the front door is monitored. Specifically, the output of any of the door opening detection sensors S-1 to S-4 is monitored. Which sensor output is monitored is determined in advance. For example, the CPU of the main board 1 randomly selects a sensor at a timing such as when the power is turned on, when the door is opened or closed, or when the setting is changed. Alternatively, a switch for selecting a sensor may be provided, and the sensor used with this switch may be selected. The selected sensor is used to detect the opening (or closing) of the door, and the other sensors are used to detect fraud. Eventually, all the outputs of the sensors S-1 to S-4 are monitored by the CPU of the main board 1.

S7b: When only the output of the door opening detection sensors S-1 to S-4 selected detects that the door is open (YES), it is considered a normal operation. Accept. On the other hand, when the output of the unselected one detects that the door is open (NO), it is considered an illegal act, so the processes of S8 and S9 are performed. Since a sensor that has not been selected should not operate, the fact that its output has become active is likely that work has been added to the output of the sensor. For example, it is conceivable that the sensor output line is forcibly grounded to create a door open state. Since some of the multiple sensors are selected at random, a person who commits fraud cannot predict which sensor is being used, and is likely to work on an unselected sensor .

  The sensor selection will be further described with reference to FIG. FIG. 6 shows the sensor selection operation in hardware, but in actuality, it can be realized in software by the CPU of the main board 1 or in hardware by an electrical or mechanical switch. It can also be realized. Switches SW-1 to SW-4 are provided at the outputs of the door opening detection sensors S-1 to S-4, and it is selected whether the outputs are used for door opening determination or fraud determination. It can be done. In FIG. 6, only the sensor S-3 is used for door opening determination, and others are used for fraud determination. Correspondingly, each sensor is given a control signal that disables the unused sensors S-1, S-2, and S-4. For example, in the case of a photo interrupter, the driving current of the LED on the transmission side is cut off, or the power supplied to the IC or switch of the sensor is cut off. Alternatively, the movable part of the mechanical sensor may be fixed. If it sets as mentioned above, only sensor S-3 will change an output according to opening and closing of a door, but other sensors will not change an output regardless of opening and closing of a door.

(3) Monitor the order of detection of a plurality of sensors Based on the plurality of door opening detection sensors, it is determined whether the door is open or closed. At the same time, the detection order of the plurality of door opening detection sensors is stored in advance, and error processing is performed when the detection order of the plurality of door opening detection sensors does not match the order stored in advance, or the internal setting is changed. Do not allow. Due to differences in sensor mounting position, sensitivity, etc. (mechanically, the distance to the contact surface of the detection switch is long, etc.), the sensors that perform detection have a certain order. For example, as shown in FIG. 3, when sensors of the same type are attached to rails 150d and 151d, doors are arranged in the order of sensors S-1, S-2, S-3, and S-4 from the relationship with the position of the hinge. (Sensor S-4 near the hinge detects the opening of the door the latest). The reverse occurs when closing the door. This is used to record the order of sensors that detect the opening of the door when it is normally opened, and to prevent fraud by comparing whether the order matches that when detecting the opening of the door. In the case of cheating, it is unlikely that the sensor detection order will be as previously recorded. The detection order may be recorded automatically when the door is opened and closed.

  A flowchart of the above process is shown in FIG. Since FIG. 7 is almost the same as FIG. 4, only differences (S1a, S6b and S7c) will be described.

S1a: Since the front door is opened before the operation of turning off the power (S1b), the outputs of all or part of the door opening detection sensors S-1 to S-4 are monitored. Which sensor output is monitored is determined in advance. The sensor state (door open or closed) and its detection order are stored.
S6b: The detection order of the door opening detection sensor stored in S1a is read. At this time, the state of the front door may be monitored, and the process of S6b may be executed when the door opening detection sensors S-1 to S-4 detect the door opening (or closing).

S7c: When the door opening detection sensors S-1 to S-4 detect the opening (or closing) of the door, and the detection order matches the pre-stored order (YES), it is considered a normal operation. Therefore, the process after S10 is performed and the setting change is accepted. On the other hand, if the actual detection order does not match the pre-stored order (NO), it is considered an illegal act, so the processes of S8 and S9 are performed. If the detection order does not match, there is a high possibility that this is an illegal act.

The door opening detection order registration process will be described with reference to FIG.
FIG. 8 (a) automatically stores the order when the door is opened. The process proceeds to the detection order registration mode of the door opening detection sensor (S11). The mode may be automatically shifted to immediately after the power is turned on. The front door is opened (S22), and the detection order of the sensors at that time is stored (S23). Then, the registration mode is canceled (S24). Canceling the registration mode may be performed manually with a switch or the like, or may be performed automatically upon receipt of the detection order.

  You may make it switch on / off of registration mode with a switch (for example, switch provided in the inside of a game machine). In this case, as shown in FIG. 8B, it is convenient to store the detection order of the sensors when the front door is closed. However, since the detection order of closure is reverse to that in the case of opening, it is necessary to reverse the order (S23a).

  According to the first embodiment of the invention, by providing a plurality of door opening detection sensors, it is possible to prevent fraud and to prevent fraud, and to detect the presence or absence of fraud by monitoring the detection order and timing of the sensors. It becomes possible to judge.

Next, how to attach the sensor S and specific examples of the sensor will be described.
The transmission part and the reception part of the door opening detection sensor S are each attached by an attachment mechanism using a screw or the like. An example is shown in FIG. FIGS. 9A to 9C are views of the state where the sensors S-Ra and / or S-Rb are attached to the first rails 150a and / or 150b as viewed from above. Since the mounting method of the second rail 151 is the same, the description thereof is omitted.

  FIG. 9A shows a state in which the sensor SR is attached to the rail 150 having an L-shaped cross section using the attachment mechanisms 152-1 and 152-2. The attachment mechanism 152-1 is a bracket having a U-shaped cross section, and has a sensor SR attached on one side and a screw hole provided on the other side. The sensor 15 is fixed by fitting the groove of the metal fitting 152-1 into the rail 150, screwing the mounting screw 152-2 into the screw hole, and applying the tip of the screw 152-1 to the rail 150. If the screw 152-2 is loosened, the sensor SR can be moved along the rail and can be fixed again at an arbitrary position.

  FIG. 9B shows a state in which the sensor SR is attached to the rail 150 having a C-shaped cross section by the attachment mechanism 152-3. The attachment mechanism 152-3 is provided with a groove that fits the end of the rail 150, so that the sensor SR can move on the rail 150. Preferably, a spring (not shown) is provided in the groove of the attachment mechanism 152-3, and the contact resistance with the rail 150 is increased by pressing with the spring, so that the sensor SR does not move (fall) naturally.

  FIG. 9C shows a state in which the sensor SR is attached to the rail 150 having an L-shaped cross section using attachment mechanisms 152-4 and 152-5. The plate-like attachment mechanism 152-4 is provided with a screw hole and is attached with a screw 152-4 penetrating the rail 150. Preferably, several through holes are provided in the rail 150 in advance. In this case, it becomes impossible to attach the sensor SR at all positions of the rail 150, but there is no practical problem if a large number of through holes are provided. On the contrary, there is an advantage that the alignment of the sensor SR and the sensor ST can be easily performed (Note that the “arbitrary position” in the present invention is any of a plurality of positions (positions of the through holes) provided in advance). This does not mean that the sensor mounting position can be continuously selected over the entire range of the rail).

  The installation location of the conventional door opening detection sensor is fixed. Since the installation location is clear, it is subject to fraud. For example, there is a possibility that an illegal act is performed using an instrument that does not activate the sensor. Therefore, a mechanism that can customize (arbitrarily set) the position of the door opening detection sensor is provided. Specifically, when installing the door opening detection sensor, a rail-like mechanism that can move up and down is provided, and the door opening detection sensor can be freely moved and fixed on the rail. Not only can the position of the door opening detection sensor be changed for each device by the above-mentioned mechanism, it can also be changed after shipment.

  Next, the door opening detection sensor will be described. For example, a sensor such as a photoelectric switch (a combination of a light emitting diode and a photodiode or a photo interrupter) including a transmitter and a receiver is used as shown in FIG. In addition, mechanical switches such as a micro switch and a reed switch, a potentiometer that measures the distance when the door is opened, and a rotary encoder that measures the angle when the door is opened can be used as the door opening detection sensor.

  FIG. 10A shows a state where a mechanical switch is attached as a sensor S. FIG. FIG. 10A is a top view, and the display of the rail 150 is omitted in the figure. When the front door 130 is closed (dotted line state), the movable part A of the sensor S is pushed in by the front door 130 and the switch contact is turned on, but the front door 130 is open (solid line). In the state), the movable part A of the sensor S protrudes (state A ′). In this state, the switch contact is turned off.

  FIG. 10B shows a state in which the photoelectric device is attached as the sensor S. The sensor S includes a light receiving element S-PD such as a photodiode, a cylindrical case S-s that covers the light receiving element S-PD, and a lid (shielding portion) Sr that covers an opening of the case S-s. . When the front door 130 is closed (dotted line state), the opening (front surface) of the case S-s of the sensor S is covered with a lid (shielding portion) S-r provided on the front door 130, so that the light receiving element S-PD does not detect light (ON state). When the front door 130 is opened (solid line state), the front surface of the light receiving element S-PD is opened to detect light (off state).

  In FIG. 11A, a mechanical switch is attached as a sensor S, an operation part SW such as a wire or an arm is provided inside the front door 130, and an action end S-Wa is provided at the end thereof. When the front door 130 is sufficiently opened, the action end S-Wa moves the movable part A of the switch S, so that the switch S is turned off. The movable part A is biased in the direction of the arrow in the figure, and is turned on when the front door 130 is closed.

  FIG. 11B shows an example in which an electric displacement measuring instrument such as a potentiometer is used as the sensor S. The electrical displacement (resistance value, voltage value, etc.) of the sensor S changes by opening and closing the front door 130. By comparing this output with a predetermined reference value by a comparator, the sensor S can be turned off when the front door 130 is opened by a certain level (threshold) or more.

  11 (a) and 11 (b), the open state can be detected when the front door 130 is opened by a predetermined distance or angle. 10A can be similarly configured by adjusting the mounting position of the switch and the length of the movable portion.

  As described above, if the installation position of the door opening detection sensor is made variable, an illegal act such as adding a work to the sensor aiming at a specific installation position by changing the position of the sensor for each individual gaming machine or its appliance Can be disabled. That is, since the position of the door opening detection sensor is not constant and it is difficult to grasp the position, it is possible to suppress the above fraud. Even after shipment, the mounting position of the door opening detection sensor can be changed, which is more effective.

Embodiment 2 of the Invention
The attachment position of the door opening detection sensor may be made variable, and the sensor may be automatically moved. Hereinafter, the apparatus / method according to the second embodiment of the present invention will be described with reference to FIGS.

  FIG. 12 shows a block diagram of a gaming machine according to the second embodiment of the invention. A sensor driving unit 160 moves the door opening detection sensor S. The sensor driving unit 160 includes a movement timing determination unit 160a that determines whether or not it is an opportunity (timing) to move the sensor S, and a movement amount determination unit 160b that determines the movement amount of the sensor S when moving. Although the sensor may be moved at an arbitrary timing, it can be considered that the sensor is moved each time the door is opened and closed from the viewpoint of preventing fraud. This is because, even if the position of the sensor S is stolen when the door is opened, it is difficult to work on the sensor S if the sensor S automatically moves after the door is closed. Similarly, the sensor S may be moved at the timing of setting change or power on / off which is an operation performed by opening the door.

  FIG. 13 is an explanatory diagram of the drive mechanism of the sensor drive unit 160. FIG. 13A is a front view of the sensor SR mounted state (the display of the housing 120 is omitted). FIG. 2B is a cross-sectional view taken along the line AA. The sensor S-R is attached to the rail 150 having a C-shaped cross section by the attachment mechanism 160-1. The mounting mechanism 160-1 is provided with a groove that fits into the end of the rail 150 and a screw hole. The groove allows the sensor SR to slide on the rail 150, and a screw that passes through the screw hole. It is driven up and down by 160-2. The screw 160-2 is provided over the entire rail 150, and is rotatably supported at the upper end and the lower end of the rail 150, for example. A motor M is attached to one end of the screw 160-2 (the upper end in the illustrated example). The sensor S-R can be stopped at an arbitrary position by driving the motor M by the sensor driving unit 160 and rotating the screw 160-2. Note that FIG. 13 is an example, and another mechanism can be used as a sensor driving mechanism.

  FIG. 14 is a flowchart of the movement process of the door opening detection sensor. First, it is determined whether or not it is an opportunity (timing) for sensor movement (S31). For example, if the sensor S is moved when the door is opened and closed as described above, the front door opening and closing signal, the setting change signal and / or the power on / off signal are monitored, and a determination is made based on these signals. When it corresponds to the trigger for moving the sensor (YES in S31), the movement amount or the position after the movement is randomly determined (S32). Although it may always be moved by a fixed amount or a plurality of predetermined positions may be moved in order, it is preferable to determine at random in order to make it difficult to predict the position of the sensor S. It is checked whether the determined movement amount or the position after movement is within the movable range (S33). If it is within the movable range (YES in S33), the sensor is moved to the determined position (S34). If it is not within the movable range (NO in S33), the determined amount of movement or the position after movement is discarded and reset (S35). This is because the movement range of the sensor is limited, and is preferably moved within the range. If this process is not performed, the probability that the sensor is located at the upper end or the lower end increases, and the position of the sensor may be easily predicted.

  According to the second embodiment of the present invention, the position of the door opening detection sensor can be automatically and frequently changed, so that illegal acts can be made more difficult.

  In the above description, the example in which the sensor is automatically moved on one rail has been described. However, the present invention can be applied to a case where the sensor is divided into a transmission unit and a reception unit as shown in FIG. In this case, the driving mechanism of FIG. 13 is provided on each of the first rail and the second rail, the processing of FIG. 14 is executed for one of the transmission unit and the reception unit, and the other is followed by the transmission unit and the reception unit (door (When closed) may be controlled to be at the same position.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
