Description

  The present invention relates to an anti-fraud device for a spinning-type gaming machine that can detect fraudulent acts performed on the spinning-type gaming machine.

  In a conventional swirl type gaming machine, the number of game media such as medals inserted is counted in order to operate the gaming machine. In order to count the number of game media thrown from the slot of this gaming machine, a light emitting part and a light receiving part are respectively provided on both sides of the alignment passage connected to the slot for passing the game medium. A configuration using photosensors arranged so as to face each other is known. In this configuration, when a game medium such as a medal inserted from the insertion slot passes through the alignment passage and passes between the light emitting unit and the light receiving unit of the optical sensor, the game medium blocks light from the light emitting unit to the light receiving unit. At this time, the light receiving unit outputs a detection signal to enable counting of game media.

  However, in a gaming machine configured to count the game medium by outputting a detection signal when the light from the light emitting unit is blocked by the game medium, a light emitting element such as a diode is provided at the tip. By inserting a rod-like or plate-like instrument from the slot, etc., and blocking the light from the light emitting part with this instrument, the light emitting element provided at the tip part blinks, so that the light from the light emitting part is caused by the passage of the game medium Goto acts that create a state of being blocked and illegally increase the number of credits in the credit device of the gaming machine are rampant.

In order to deal with such a situation, sensors are respectively arranged in the upstream and downstream portions of the alignment passage through which the game media inserted from the insertion port passes, and one game medium input from the insertion port is located in the upstream portion. There has also been proposed a gaming machine that measures the time from passing through a sensor to passing through a downstream sensor, and judging that the time is shorter than a predetermined time.

A first embodiment in which the present invention is applied to a slot machine will be described below with reference to the drawings.
As shown in FIG. 1, the gaming machine A includes a device body 1 having a substantially box shape, and a door 2 partially formed of a transparent member is provided on the front surface. In the upper space 3 in the apparatus main body 1, a main body substrate 4 is installed on the inner left side surface, and a reel 5 is disposed in a substantially central portion. In the lower space 7 in the apparatus main body 1, a hopper 8 is installed at a substantially central portion of the lower surface.

  A substantially central portion of the door 2 is provided with an insertion port 9 penetrating the door 2, and an alignment passage 10 is provided on the inner side surface of the door 2 so as to be continuous from the insertion port 9.

  Further, as shown in FIGS. 1 and 2, the main body credit sensor 12 and the first sensor 13 are spaced apart so as to face both sides of appropriate portions of the alignment passage 10 provided inside the door 2. Provide. When the distance between the sensor 12 for the main body credit and the first sensor 13 is small and both sensors are provided close to each other, a selector goto is performed by thrusting an instrument having a light emitting element at the tip into the insertion port 9. Since both sensors malfunction at the same time, it is necessary to provide an interval so that such a situation does not occur. Further, in this embodiment, the main body credit sensor 12 is provided upstream of the alignment passage 10 close to the insertion port 9 and the first sensor 13 is provided downstream of the alignment passage 10. The first sensor 13 may be provided on the upstream side close to the insertion port 9. In short, the two sensors may be provided on both sides of the alignment passage 10 at a certain interval. In the present embodiment, the main body credit sensor 12 and the first sensor 13 use optical sensors each having a light emitting portion and a light receiving portion. In FIG. 2, for easy understanding, a state where a medal M, which is a game medium, is being inserted is shown.

  Next, as shown in FIGS. 1 and 3, a payout opening 14 through which game media is paid out is provided in a substantially central portion of the outer front surface of the hopper 8, and the upper and lower sides of the payout opening 14 are opposed to each other. A second sensor 15 is provided to do this. 1 and 3, the configuration in which the second sensor 15 is provided on the outer surface of the discharge outlet 14 of the hopper 8 is shown. A second sensor 15 that is an optical sensor composed of a light receiving unit may be provided.

  Further, in the present embodiment, as the main body credit sensor 12, the first sensor 13, and the second sensor 15, as shown in FIGS. 1 to 3, the light emitting unit and the light receiving unit are physically separated, and the light emitting unit and the light receiving unit are separated. Will be described using a separate optical sensor of the same shape, but a transmission type optical sensor in which the light emitting part and the light receiving part are connected in a U-shape or an integrated type in which the light emitting part and the light receiving part are configured close to each other. A configuration using a reflection-type optical sensor, further an inductive proximity sensor or a microswitch-type sensor may be used. In short, the invention is not limited to the optical sensor, and any type of game medium that can detect an inserted or paid-out game medium may be used.

  Next, FIG. 4 is a block diagram conceptually showing the configuration of this embodiment applied to the gaming machine A. As described above, the gaming machine A is connected to the main body board 4 that controls the machine control of the gaming machine A, such as rotating the reel 5 and giving a command to pay out gaming media such as medals, and the insertion port 9. A main body credit sensor 12 for detecting the insertion of game media in the alignment passage 10 and outputting a signal is provided. The sensor 12 and the main body substrate 4 are connected so that an output signal from the sensor 12 is input to the main body substrate 4. And, as with general swing-type gaming machines, a signal indicating the number of game media provided for the game (hereinafter referred to as `` hitting ball signal ''), a signal indicating the number of game media to be paid out when winning (hereinafter referred to as `` hitting ball signal '') And the number of game media stored in the gaming machine A by the main body credit 16 provided on the main body board 4 based on the output signal from the main body credit sensor 12. Count and display. The “number of game media provided for the game” refers to the number of medals bet in one game, and the “number of game media to be paid out when winning a prize” includes a reel pattern. The number of medals determined in advance by the combination and paid out to the main body credit 16 is indicated.

Further, the gaming machine A is provided with a first sensor 13 at a predetermined interval from the main body credit sensor 12 at an appropriate position of the alignment passage 10 connected to the insertion port 9 as described above. A second sensor 15 is provided at the outlet 14. These two sensors are connected to the hall computer 11 via the relay board 6. The hall computer 11 is connected to the main body substrate 4 via a concentrated terminal (not shown) provided on the main body substrate 4. By connecting the hall computer 11 to the main body substrate 4, it is possible to cause the hall computer 11 to input a hitting signal and an outgoing ball signal. When the first sensor 13 and the second sensor 15 detect a game medium, a signal output from the first sensor 13 (hereinafter referred to as “medal input signal”) and a signal output from the second sensor 15 ( (Hereinafter referred to as a “medal payout signal”), a batting signal and a ball signal are input to the hall computer 11, and the game media is counted using the virtual credit 17 provided in the hall computer 11. Specifically, the game media count calculation is performed by adding the number of game media obtained from the medal input signal and the number of game media obtained from the output ball signal, and the number of game media obtained from the medal payout signal and the hit ball The number of game media obtained from the signal is subtracted.
The relay board 6 serves to convert a medal input signal and a medal payout signal into a digital signal so that the signal can be input to the hall computer 11. Therefore, the relay board 6 may be built in the hall computer 11 without the relay board 6 interposed. In addition, the relay board 6 cannot be placed in the gaming machine A in accordance with the current law, but when the law revision makes it possible to place in the gaming machine A, the relay board 6 is placed in the gaming machine A. Good. Further, FIG. 4 shows a configuration in which the relay board 6 and the hall computer 11 are directly connected. However, a stand computer that collects data such as a gaming machine A, a gaming media lending machine, a counter, and the like is installed on each island. In addition, an island computer that collects data collected by each computer in the island may be interposed (not shown). Further, the base computer and the island computer are interposed between the relay board 6 and the hall computer 11, and the main board 4 and the base computer are provided on the main board 4 without directly connecting the main board 4 and the hall computer 11. It is also possible to connect via a centralized terminal so that the ball signal and the ball signal are input to the hall computer 11 via the platform computer and the island computer. If such a configuration is adopted and calculation is performed by the stand computer or island computer and the calculation result is transmitted to the hall computer 11, the burden on the hall computer 11 can be reduced.

  Next, the operation of the virtual credit 17 will be described using FIG. 5 according to the actual game flow. FIG. 5 is a flowchart, which is composed of a plurality of types of frames. A single solid line frame indicates processing by the player, a single dotted line frame indicates processing by the virtual credit 17, and a double frame A solid line frame indicates processing by the main body substrate 4. The virtual credit 17 has an initial value of 0. In other words, it returns to 0 when the store opens. In addition, when the predetermined range which is the value of the virtual credit 17 due to the normal operation of the gaming machine A is 0 or more and 50 or less, when the value of the virtual credit 17 becomes smaller than 0 or larger than 50, the hall computer 11 detects an abnormality as an error and outputs an error signal. In the present embodiment, the predetermined range is 0 to 50, and when the value of the virtual credit 17 is smaller than 0 or larger than 50, an abnormality is detected as an error. For example, the predetermined range can be freely set by changing the setting of the hall computer 11. Therefore, for example, the predetermined range may be set to -100 or more and 100 or less. In addition, in consideration of the case where the detection of the game medium by the first sensor 13 and the second sensor 15 is not completely accurate and malfunctions, for example, the predetermined range is set to −5 to 55 and the value of the virtual credit 17 is − The hall computer 11 may be set so that an abnormality is detected as an error when it becomes smaller than 5 or larger than 55. Furthermore, as a measure after the hall computer 11 detects an abnormality as an error, a measure such as a warning lamp provided in the gaming machine A is turned on or the power of the gaming machine A is forcibly turned off can be considered. In addition, if a camera (not shown) that shoots the player is placed near the game table, the date and time when the error was detected, and the game table, an error history is created along with the captured image. It may be stored (accumulated) in the hall computer 11. Thereafter, a store employee or the like presses the clear button provided in the hall computer 11 to reset it.

  Here, when the player inserts, for example, five medals from the insertion slot 9, the medals pass through the alignment passage 10 connected to the insertion slot 9, so that the first sensor 13 passes every time one medal passes. Detected, the medal input signal is output five times, and the value of the virtual credit 17 increases by 1 to 5. Here, when a clearing (= cancel) button (not shown) provided in the gaming machine A is pressed, five medals are paid out from the hopper 8 to a lower plate (not shown) of the gaming machine A. At this time, the second sensor 15 provided at the payout outlet 14 detects every time a medal passes, outputs a medal payout signal five times, and the value of the virtual credit 17 decreases by 1 and returns to 0. .

  If the start lever provided in the gaming machine A is pushed down without pressing the checkout button, three medals are betted, a hitting signal is output from the main board 4, and the value of the virtual credit 17 is reduced by 3, Result 2 is obtained. Then, the reel 5 rotates and the game is started. As a result of the game, if all the symbols on the reels 5 are won, a medal corresponding to the combination determined for each aligned symbol is paid out. For example, when the number of medals to be paid out by a winning combination is 15, a payout signal is output from the main body substrate 4, and the value of the virtual credit 17 is increased by 15 to become 17. Normally, the main body credit 16 provided in the gaming machine A is set to store up to 50 medals, and in this case, the medals are not actually paid out from the payout opening 14, and the main body credit 16 Only increases from 2 to 17. The main body credit 16 is currently set in the range of 0 to 50 based on laws and regulations, but there is a possibility that the upper limit may be changed due to future legal revisions. In that case, the range of the virtual credit 17 can be freely set by changing the setting of the hall computer in accordance with the upper limit value of the main body credit 16.

  On the other hand, for example, when the number of medals paid out by the winning combination is 50, a payout signal is output from the main board 4 and the value of the virtual credit 17 is increased by 50, resulting in 52. In this case, considering that there is a time lag until the medal payout signal from the second sensor 15 by the actual payout of the medal is input to the hall computer 11, an allowance time is provided and an error is immediately detected as an error. Do not detect. If two sheets exceeding the 50 sheets pass through the second sensor 15 and the medal payout signal is output twice within this permissible time, it is determined to be normal. If the value of the virtual credit 17 remains 52 even after the allowable time is exceeded, an abnormality is detected as an error.

  Next, let us consider a case where a fraudulent act such as a so-called selector goth act is performed. Assume that a device with a light-emitting element at the tip is inserted from the slot 9 of the gaming machine A, the main body credit sensor 12 is malfunctioned, and the value of the main body credit 16 is increased to 50. In this case, since the medal has not actually passed through the alignment passage 10, the first sensor 13 does not operate, and the virtual credit 17 remains at the initial value of 0. When the checkout button is pressed, 50 medals are paid out from the hopper 8 to the lower plate of the gaming machine A. At this time, the second sensor 15 provided at the payout opening 14 detects each time a medal passes, outputs a medal payout signal 50 times, and the value of the virtual credit 17 of the hall computer 11 decreases by one. As a result, it becomes -50. In this case, since it is below the lower limit of 0, the hall computer 11 detects an abnormality as an error. An abnormality may be detected as an error after the payout is completed, or an abnormality may be immediately detected as an error when the value of the virtual credit 17 becomes smaller than 0. 11 can be freely changed by setting.

  In the above case, if the start lever provided in the gaming machine A is pushed down without pressing the checkout button, three medals are betted, a batting signal is output from the main board 4, and the value of the virtual credit 17 is Although it decreases by 3, the value of the virtual credit 17 is -3 because it is the initial value of 0. Also in this case, since it is below the lower limit of 0, the hall computer 11 detects an abnormality as an error.

  In addition, when the device provided with the light emitting element at the tip is inserted from the insertion port 9 of the gaming machine A and only the first sensor 13 is erroneously operated, and the value of the virtual credit 17 is larger than 50, the hall computer 11 is in error. As an abnormality is detected. Further, when a sword-to-play action is performed in which a device is inserted through the gap of the gaming machine A and the game medium is illegally paid out by pulling the spring of the hopper 8 with a wire or the like, the medal is removed from the hopper 8 by the gaming machine A. When paid out to the lower plate, the second sensor 15 provided at the payout outlet 14 detects each time a medal passes, outputs a medal payout signal, and the value of the virtual credit 17 decreases by one. However, since the initial value of the virtual credit 17 is 0, the value of the virtual credit 17 becomes smaller than 0 which is the lower limit value, and the hall computer 11 detects an abnormality as an error.

  In the configuration of the first embodiment, if the counting operation of the virtual credit 17 is continued for a long time, an error may occur between the value of the virtual credit 17 and the value of the main body credit 16. In particular, the second sensor 15 provided at the payout port 14 detects more game media than the number of game media actually paid out when the game media rampages or rebounds in the vicinity of the payout port 14. . Then, the value of the virtual credit 17 becomes 0 or less by the medal payout signal at the time of paying out the game medium, and an abnormality is detected. Therefore, in the present embodiment, in order to increase the accuracy of the value of the virtual credit 17 to be calculated by matching the value of the virtual credit 17 with the value of the main body credit 16 in a fixed case, a new configuration is added to the configuration of the first embodiment. It has been improved by adding a configuration.

  FIG. 6 is a block diagram conceptually showing the configuration of the present embodiment applied to the gaming machine B, in which correction means is added to the first embodiment. Here, three light emitting elements 18 to 20 are provided on the main board 4 of the gaming machine B, respectively. The light emitting elements 18 to 20 are desirably attached together with other components when the main body substrate 4 is manufactured. For example, when the clearing button of the gaming machine B is pressed, the light emitting element 19 has a value of the main body credit 16 of 0, and the light emitting element 20 has a value of 50 of the main body credit 16, respectively. In response to a signal transmitted from the main board 4, a current flows through each light emitting element to emit light. In short, each light emitting element emits light when the settlement button of the gaming machine B is pressed or when the value of the main body credit 16 becomes a predetermined value.

  A configuration of light emission of the light emitting elements 18 to 20 will be described. The main body board 4 of the gaming machine B is specifically a CPU (Central Processing Unit, not shown) provided on the main body board 4, and as described above, the ball signal, the ball signal, and the main body credit sensor 12 Based on the output signal from the player, the player calculates and displays the number of game media stored in the game machine B by the player credit 16 provided on the player board 4. Therefore, this CPU is set by setting a program so that a signal is transmitted to the light emitting element 19 when the value of the main body credit 16 becomes 0, and when the value of the main body credit 16 becomes 50, the light emitting element. A program is set so that a signal is transmitted to 20. In addition, a sensor for detecting the depressing of the clearing button of the gaming machine B is provided in the vicinity of the clearing button (not shown), this sensor is connected to the main body board 4, and the CPU of the main body board 4 receives the clearing button depressing signal from this sensor. A program is set and set so that a signal is transmitted to the light emitting element 18 when it is received. Each light emitting element emits light upon receiving a signal from the CPU.

  In another example of the light emission configuration of the light emitting elements 18 to 20, in the normal gaming machine, the main body credit 16 is displayed as a segment, but the segment display is photographed with a CCD camera, and the main body credit is obtained from the photographed data by computer processing. A configuration may be adopted in which the value of the credit 16 is recognized, and when the value becomes 0, the light emitting element 19 emits light, and when the value becomes 50, the light emitting element 20 emits light. In addition, a sensor for detecting the depression of the settlement button provided in the vicinity of the settlement button of the gaming machine B is directly connected to the light emitting element 18, and a signal is transmitted to the light emitting element 18 when the sensor detects the depression of the settlement button. It may be configured.

  In the gaming machine B, in order to detect light from the light emitting elements 18 to 20, the same number of light receiving sensors 21 to 23 are provided at positions near the light emitting elements 18 to 20, respectively. The light receiving sensors 21 to 23 play a role of converting signals from the light emitted from the light emitting elements 18 to 20 into electric signals. The light receiving sensors 21 to 23 are configured such that current flows when light is detected, and current does not flow when light is not detected, and thus convert the optical signal into a digital electrical signal. In FIG. 6, the light receiving sensors 21 to 23 are connected to the hall computer 11 via the relay substrate 6. However, since the signals output from the light receiving sensors 21 to 23 are digital electric signals as described above, there is no need to convert the signal by the relay board 6, and the signal is simply passed through the relay board 6 together with other signals. There is only. Therefore, the light receiving sensors 21 to 23 may be directly connected to the hall computer 11. When any of the light receiving sensors detects light from the light emitting elements 18 to 20, a detection signal is input to the hall computer 11. And the hall computer 11 performs the process which makes the value of the virtual credit 17 0 or 50, for example. More specifically, when the clearing button of the gaming machine B is pressed and when the value of the main body credit 16 becomes 0, the value of the virtual credit 17 is set to 0. Further, when the value of the main body credit 16 becomes 50, the value of the virtual credit 17 is set to 50. That is, the value of the virtual credit 17 is corrected according to the value of the main body credit 16.

  If the correction means is set to always operate and the value of the virtual credit 17 is corrected in accordance with the value of the main body credit 16, the object of the present invention of detecting an unauthorized goto action cannot be achieved. Therefore, it is desirable that the correction means is configured to be selectively operated. In this embodiment, the number of light emitting elements is three, but the number of light emitting elements is not limited to this. For example, even if three light emitting elements are provided as in this embodiment, it is not necessary to set all the light emitting elements to emit light, and one or two of the three light emitting elements are set to emit light. May be.

  Other configurations and operations of the present embodiment are the same as those of the first embodiment.

  The first sensor 13, the second sensor 15, and the light receiving sensors 21 to 23 in the first embodiment and the second embodiment perform an illegal goto action after the gaming machine A and the gaming machine B are manufactured and arranged in each store. In order to detect, an employee of each store attaches to each gaming machine A or gaming machine B using double-sided tape or the like while looking at the installation manual or the like. However, it is difficult to adjust the position of each sensor installation, the installation location is shifted, and each sensor may not be able to detect the game medium properly. Depending on the skill and skill of the person installing each sensor, There may be a difference in detection accuracy. Moreover, since it is difficult to adjust the position of each sensor, complicated work is required. Therefore, when installing each sensor such as the payout opening 14 or the like, as shown in FIG. 7, the positioning member 24 is provided for securing and positioning the space for mounting each sensor, and at least two adjacent outer surfaces of each sensor are provided. You may make it the structure previously provided so that it may contact | abut. In FIG. 7, a U-shaped sensor 25 in which a light emitting portion and a light receiving portion are integrally molded is shown as the second sensor 15 installed at the discharge outlet 14 of the hopper 8. The positioning member 24 may be integrally molded around the outlet 14 such as the hopper 8 by a press or the like, or may be attached as a separate body. Since the positioning member 24 is provided in advance, when the sensor is attached to each sensor, if the sensor 25 and the like are provided by bringing the two outer surfaces such as the sensor 25 into contact with the positioning member 24, each sensor can be simplified. In addition, it can be installed at an appropriate position.
