Description

  The present invention relates to a gaming machine.

  Conventionally, there is a gaming machine (bullet ball gaming machine) provided with a gaming board provided with a gaming area in which a gaming ball is launched. The game board is covered with, for example, a frame member into which a glass plate is fitted, and the game area is provided between the board surface of the game board and the frame member. The gaming machine pays out a winning ball corresponding to the winning when the gaming ball launched into the gaming area wins a predetermined winning opening.

  In such a gaming machine, the frame member covering the front surface of the gaming machine is pulled to be distorted, a gap is created between the frame member and the game board, and a wire or the like is inserted from this gap to the vicinity of the winning hole of the game board There are known fraudulent acts such as bending the nails of the player and causing the winning sensor to malfunction. In addition, various illegal acts such as illegally winning a game ball at a winning opening by hitting a gaming machine and applying an impact to change the behavior of the game ball are known.

  As another gaming machine, there is a gaming machine (rotational gaming machine) including a plurality of reels as a rotating body with a plurality of symbols. Each reel starts rotating when the player inserts a medal and operates the start lever. Thereafter, the reels are sequentially stopped by operating the stop button. A lottery will be conducted on condition that the medal is inserted and the start lever is operated, and the result of the lottery is winning, and a predetermined number of medals will be provided on the condition that the player has stopped the winning symbol on the preset active line. To be paid out.

  Such a gaming machine includes a box-shaped housing having an opening on the front side and a front door attached to the front side of the housing so as to be openable and closable, and a control device or the like is disposed inside the housing. As a result, the front door covers the opening and is used for games. Therefore, there is known an illegal act in which a player illegally operates a gaming machine by opening the front door or creating a gap. Further, there is a possibility that a player who is excited at the time of operating the stop button may damage the gaming machine by hitting it strongly.

  For example, by attaching a piezoelectric element to the glass frame (frame member) of a gaming machine, for example, the distortion generated when a wire or the like is inserted and the impact applied from the outside of the gaming machine are detected as voltage changes. However, when the detected voltage is greater than a certain level (threshold), it is determined that the act is fraudulent and a game is stopped or an alarm is notified (Patent Document 1).

JP 2008-18003 A (paragraphs 0028-0035)

  However, since the electromotive force of the piezoelectric element is proportional only to the “size” of the strain or impact and has nothing to do with the type, simply converting external force into voltage as described above will cause illegal acts in gaming machines. Although it was possible to detect that an external force exceeding a certain level was recognized, it was impossible to distinguish whether the external force was due to distortion or due to impact (striking).

  Therefore, even if it can be detected that a fraudulent act has been performed, it is not possible to specify what kind of fraudulent act it is, so all the same measures are taken against fraudulent acts that apply external force such as distortion or impact to the gaming machine (for example, , The same abnormality notification).

  In addition, even if the same fraudulent act, the magnitude of the voltage generated from the piezoelectric element differs depending on the magnitude of the force applied when the gaming machine is distorted and when the impact is applied by hitting the gaming machine. If a threshold is set with one as a reference, there is a risk that fraudulent acts cannot be detected accurately. For example, if the voltage generated when the gaming machine is distorted is smaller than the voltage generated when the game machine is struck, setting a threshold with reference to the voltage generated when the gaming machine is distorted may result in fraudulent activity. Even if an impact that is so small is applied to the gaming machine, a voltage exceeding the threshold may be generated and detected as abnormal. Conversely, if the threshold is set based on the voltage generated when the gaming machine is struck, the voltage generated when the gaming machine is distorted is less than the threshold and may not be detected as abnormal.

  Based on the above background, the present invention proposes a gaming machine that can determine what kind of external force is applied when an external force is applied to the gaming machine.

In order to solve the above-described problem, a gaming machine according to the present invention is a gaming machine capable of executing a predetermined game, and detects a change in external force applied to the gaming machine and outputs the voltage. And a filter means for separately passing the voltage output from the detection section for each of a plurality of frequency bands, and a plurality of frequency band voltages passing through the filter means are provided for each of the plurality of frequency bands. And a comparison means for comparing with the set threshold value.
In addition, the gaming machine has a notifying means for notifying abnormality when the comparison result by the comparing means is a predetermined result.
The gaming machine includes a payout device for paying out a predetermined game value according to the game result,
The payout device stops payout of the game value when the comparison result by the comparison means is a predetermined result.
The gaming machine includes a game ball launching means for launching a game ball, and the game ball launching means stops the launch of the game ball when the comparison result by the comparison means is a predetermined result. To do.
Further, the gaming machine is characterized in that the progress of the game is stopped when the comparison result by the comparison means is a predetermined result.

  When an external force is applied to the detection unit constituted by a piezoelectric element or the like, the frequency characteristics of the generated voltage vary depending on the type of external force (how it is applied) and the vibration of the detection unit varies. For example, an electromotive force with a relatively high frequency is generated when an external force is momentarily applied, such as a blow, and a relatively low frequency is generated when an external force is applied so as to be gradually distorted. An electromotive force is generated.

  Therefore, it is possible to determine the magnitude for each type of external force by extracting the voltage generated from the piezoelectric element for each frequency band corresponding to the type of external force using the filter means. For example, if a high frequency voltage is measured, it can be determined that an impact has been applied, and if a low frequency voltage is measured, it can be determined that an external force such as distortion has been applied. Accordingly, if a threshold value of a different voltage is provided for each frequency band, detection according to the type of external force is possible.

  Since the external force is converted into a voltage by the detection unit and the voltage is output as a signal for each of a plurality of frequency bands by the filter unit, it can be determined how much external force corresponding to each frequency band is applied by the comparison unit.

  The best mode for carrying out the present invention will be described below with reference to the drawings. For the sake of convenience, unless otherwise noted, parts having the same operational effects are denoted by the same reference numerals and description thereof is omitted.

  First, an outline of a vibration detection device which is one of the members constituting the gaming machine according to the present invention will be described. FIG. 1A is a plan view of the detection unit 20 in the vibration detection apparatus 1, and FIG. The piezoelectric element 10 used in the vibration detection device 1 is a unimorph piezoelectric element, and has a structure in which electrodes 10b and 10c are formed on both surfaces of a piezoelectric ceramic 10a such as barium titanate, lead titanate, or lead zirconate titanate. In this embodiment, the piezoelectric ceramic 10a has a disk shape with a diameter of about 9 mm and a thickness of about 0.1 mm, and the electrodes 10b and 10c have a circular shape with a diameter of about 8 mm. One surface (the electrode 10c side) of the piezoelectric element 10 is bonded to a metal plate 12 such as brass or stainless steel, thereby forming a detection unit 20 that detects vibration. In this embodiment, the metal plate 12 has a circular shape with a diameter of about 12 mm and a thickness of about 0.1 mm.

  The detection unit 20 is configured such that when the metal plate 12 is bent in the direction shown in FIG. 2A and the piezoelectric element 10 is extended in the radial direction, the metal plate 12 is bent in the direction shown in FIG. Since the application direction of the voltage generated by the time when the metal plate 12 contracts is reversed, the vibration of the detection unit 20 causes the metal plate 12 to vibrate when the state of (a) and the state of (b) are alternately repeated. AC voltage with a frequency corresponding to Therefore, it is possible to determine how the detection unit 20 vibrates by measuring the voltage generated by the detection unit 20.

  The detection unit 20 has a metal plate 12 side bonded to a circuit board 14 such as a glass epoxy board (see FIG. 4). The circuit board 14 has a filter circuit 22 for cutting noise components from the voltage generated in the detection unit 20, an amplifier circuit 24 for amplifying the voltage that has passed through the filter circuit 22, and the voltage amplified by the amplifier circuit 24. A measurement unit 30 for measurement and an output connector 28 for outputting a measurement result from the measurement unit 30 are provided (see FIG. 3). As described above, the detection unit 20, the filter circuit 22, the amplification circuit 24, and the measurement unit 30 are integrally provided on the same circuit board 14, so that noise due to wiring or the like is reduced and high-precision sensing can be performed. Moreover, it becomes a compact vibration detection apparatus, and unitization becomes easy. Further, when the detection unit 20 is mounted on the circuit board 14, when the vibration detection device 1 is mounted on the sensing object, the detection unit 20 is caused by natural vibration of the target rather than directly mounting the detection unit 20 on the target. It becomes difficult to be affected.

  Lead wires (not shown) are respectively attached to the electrode 10b and the metal plate 12 on the surface side of the detection unit 20, and the lead wires are connected to be input to the filter circuit 22. For the bonding of the detection unit 20, it is possible to prevent vibrations from being absorbed by the adhesive by using a material having a high hardness after bonding, such as an epoxy-based adhesive. Further, when the detection unit 20, the filter circuit 22, the amplification circuit 24, and the measurement unit 30 are mounted on the circuit board 14, other circuits or the like (the filter circuit 22, the amplification circuit 24, and the measurement are within 2 mm around the detection unit 20). Part 30) is preferably not arranged. This is for suppressing the occurrence of unnecessary noise by arranging other circuits and the like.

  The filter circuit 22 cuts frequency components (noise) that are not necessary for measurement, and filters only frequency components necessary for measurement. In the present embodiment, a high-pass filter and a low-pass filter are used, and thereby components unnecessary for measurement are cut from the voltage generated by the detection unit 20. Note that the filter circuit 22 is configured by, for example, a capacitor and a resistor.

  The voltage amplification factor of the amplifying circuit 24 can be changed as appropriate. When the voltage generated in the detection unit 20 is high depending on the attachment target or attachment position, the voltage amplification factor is not so large, for example, about 3 to 5 times. When the voltage generated in the unit 20 is low, the voltage amplification factor can be increased to about 20 times, for example. The amplifier circuit 24 is configured using, for example, an operational amplifier and a resistor.

  The measuring unit 30 measures voltage values of a plurality of types of frequency bands from the input voltage, and determines whether or not each measured value exceeds a threshold. The input analog voltage is converted into a digital voltage. A / D conversion means 32 for converting to a signal, a digital filter which is a filter means 34 for filtering a voltage signal in a frequency band to be measured from the voltage signal converted by the A / D conversion means 32, and the digital filter is filtered Comparing means 36 for comparing the voltage signal with a threshold value and outputting a comparison result. The measuring unit 30 includes, for example, a ROM that stores programs for realizing the functions of the filter unit 34 and the comparison unit 36, a CPU that executes arithmetic processing based on the programs stored in the ROM, and a data work area in the arithmetic processing of the CPU. And a one-chip microcomputer having an A / D conversion function.

  For example, when measurement is performed for two types of frequency bands, a voltage signal in the first frequency band filtered by the first filter unit 34a is applied to the voltage signal input to the measurement unit 30 and A / D converted. The voltage signal of the second frequency band monitored by the first comparison means 36a and filtered by the second filter means 34b is monitored by the second comparison means 36b. And the signal according to the result of having compared each voltage signal with the threshold value predetermined about each frequency band is output. For example, when a voltage signal equal to or higher than the threshold is measured, a signal indicating that is output, and when a voltage signal equal to or higher than the threshold is not observed, a predetermined signal is output. For this reason, when fraud such as disconnection of the output line from the vibration detection device 1 is performed, the disconnection or the like can be detected by the fact that no signal can be received at the output destination of the vibration detection device 1. . In addition, it is good also as a structure which always outputs a fixed pulse signal irrespective of the comparison result with a threshold value.

  FIG. 5 and FIG. 6 each show the time change of the voltage generated in the detection unit 20 when an external force is applied to the vibration detection device 1. FIG. 5 shows a case where an external force is applied over time (distortion) so as to be gradually distorted, and FIG. 6 shows a case where an external force is momentarily applied (striking) like a blow. Here, in the case of distortion, a voltage is characteristically generated at a voltage having a frequency band of 0.1 Hz to 10 Hz, which is a relatively low frequency, particularly 1 Hz to 5 Hz. In the case of hitting, a voltage having a relatively high frequency of 10 Hz or more is generated. Depending on the game machine, a voltage having a frequency of about several kHz is generated as noise depending on the operation.

  Therefore, for example, when measuring distortion and tapping, the frequency band filtered by the first filter unit 34a is 0.1 Hz to 10 Hz, and the frequency band filtered by the second filter unit 34b is 10 Hz to 40 Hz. By doing so, it is difficult to be affected by noise, and it is possible to separate and measure distortion and hit. Further, if the frequency band to be filtered by the first filter unit 34a is set to 1 Hz to 5 Hz and the frequency band to be filtered by the second filter unit 34b is set to 20 Hz to 40 Hz, it is possible to discriminate between distortion and beating with higher accuracy. be able to.

  Note that the voltage signals filtered through the first filter means 34a and the second filter means 34b are output separately as they are (or D / A converted), and it is determined whether the threshold value has been exceeded by the comparison means provided at the output destination. You may do it. In this case, since some voltage such as noise is always output, it is not always necessary to output a constant signal as described above.

  Moreover, although the method of providing the filter means 34 in the measurement unit 30 has been shown, as another method, the voltage generated by the detection unit is branched, and the first filter circuit (bandpass filter) is provided for one and the other is provided for the other. On the other hand, it is possible to pass through a second filter circuit (band pass filter), obtain voltages of two types of frequency bands separately, and provide comparison means for each to determine whether the threshold value is exceeded.

  The circuit board 14 to which the detection unit 20, the filter circuit 22, the amplification circuit 24, and the measurement unit 30 are fixed includes, for example, a box part 41 in which plastic or the like is formed in a concave shape and a lid part 45 that fits into the box part 41. Covered with a case 40 (see FIG. 4). Through holes 14a and 14b are provided in the corners on the diagonal line of the circuit board 14, and the box part 41 and the lid part 45 also have through holes 41a and 41a at portions corresponding to the through holes 14a and 14b of the circuit board 14, respectively. 41b, 45a, 45b are provided. The through holes 41 a and 41 b on the box part 41 side are formed in the center of the columnar parts 42 a and 42 b projecting upward from the bottom surface of the box part 41, and the through holes 45 a and 45 b on the lid part 45 side are the back side of the lid part 45. Are drilled at the center of the columnar portions 46a and 46b projecting downward from the bottom. Thus, when the circuit board 14 is covered with the case 40, the circuit board 14 is sandwiched between the columnar portions 42 a and 42 b of the box portion 41 and the columnar portions 46 a and 46 b of the lid portion 45. Further, since the through holes 45a, 14a and 41a penetrate and the through holes 45b, 14b and 41b penetrate, the case 40 and the circuit board 14 can be fixed diagonally by two screws. The box portion 41 is provided with a through hole 47 at a position corresponding to the output connector 28 provided on the circuit board 14. The through hole 47 is closed by the output connector 28 in a state where the circuit board 14 is housed in the box portion 41.

  By covering the circuit board 14 with the case 40 in this manner, the detection unit 20 is blocked from the outside by the case 40, so that external air does not affect the detection unit 20. When the case 40 is not used, it is preferable to cover the detection unit 20 with an epoxy resin or the like so as not to be affected by air. The case may be covered with a case 40, or may be filled with an epoxy resin or the like in a state where the circuit board 14 is housed in the case 40. In this case, air is also shut off from the air in the case. It is not affected by. The material for coating and filling can be changed as appropriate.

  The vibration detection device 1 covered with the case 40 may be attached to the object by bonding the case 40 and the object, but screwed by a through hole provided in the case 40 and the circuit board 14. Is preferred. When the circuit board 14 is sandwiched between the box part 41 and the lid part 45, the vibration and distortion of the object are conducted to the circuit board 14 through the case 40, but the distortion and vibration of the object are screwed by screwing. Therefore, the detection accuracy is increased. Further, since the through holes for screwing are provided on the diagonal line, vibration is easily transmitted to the circuit board 14.

  Although the case where measurement is performed for two types of frequency bands has been shown, the present invention is not limited to this, and measurement can be performed for three or more types of frequency bands. In this case, it can be realized by increasing the number of filter means 34 and comparison means 36, for example.

  Although the unimorph piezoelectric element has been described as an example of the piezoelectric element 10, the present invention is not limited to this, and a bimorph piezoelectric element can also be used. A bimorph piezoelectric element has a structure in which piezoelectric elements are bonded to both surfaces of a metal plate, and outputs a voltage in accordance with a change in external force due to vibration or the like, similarly to a unimorph piezoelectric element.

Send out a game ball.

  The vibration detection device 1 is screwed to a central portion (portion indicated by A in FIG. 8) of a plate-like iron plate 127 provided over the left and right sides on the back side of the frame member 110 while being enclosed in the case 40. By fixing the vibration detection device 1 to the hard plate-like member provided over a wide range as described above, it is assumed that the external force applied to the pachinko machine 100 is applied to a position away from the fixed position of the vibration detection device 1. However, the external force is easily transmitted to the vibration detection device 1.

  A main control board 201 and a sub control board 202 are connected to the output side of the vibration detection apparatus 1 via a relay terminal board 204, and a signal output from the vibration detection apparatus 1 is connected to the main control board via the relay terminal board 204. 201 and the sub control board 202, respectively. The main control board 201 and the sub control board 202 perform processing for fraud in accordance with a signal from the vibration detection device 1.

  In the present embodiment, the vibration detection device 1 causes the player to distort the frame member 110 and intrude a piano wire or wire into the game board 101 to bend a nail and so on (so-called barbits) and the pachinko machine 100. This is to simultaneously detect fraud (so-called dotting, hitting a table) that changes the behavior of a game ball by hitting it. Here, when an external force over time such as distortion caused by a barb is applied, a voltage having a frequency band of 0.1 Hz to 10 Hz, particularly a voltage of 1 Hz to 5 Hz, is characteristically generated in the detection unit 20. In addition, when an instantaneous impact such as hitting with a stick is applied, a voltage having a frequency of 10 Hz or more is generated in the detection unit 20. The frequency of the voltage generated from the detection unit 20 due to the vibration of the game ball generated during the game, the vibration of the launching unit, the vibration of the variable winning device (opening / closing door 109a), and the vibrations of the stage effects 115 and 116 is as follows. , Both appear characteristically at several kHz.

  The filter circuit 22 includes a high-pass filter that filters a voltage having a frequency of 0.1 Hz or more and a low-pass filter that filters a voltage having a frequency of 50 Hz or less. Accordingly, the frequency band (0.1 Hz to 10 Hz) for detecting distortion and the like from the voltage output from the detection unit 20 and the frequency band (10 Hz to 40 Hz) for detecting hit and the like are included in the range of 0.1 Hz to 50 Hz. Can be filtered, and other noise components including a voltage generated by vibration of a game ball or the like can be cut. The amplifier circuit 24 is a circuit that amplifies the input voltage about three times. As a result, the voltage from which noise has been removed by the filter circuit 22 is amplified and input to the measuring unit 30.

  In the measuring unit 30, the input voltage in the frequency band from 0.1 Hz to 50 Hz is first converted from an analog voltage to a digital voltage signal by the A / D conversion means 32. Next, the first measured voltage (frequency band of 0.1 Hz to 10 Hz) and the frequency of 10 Hz to 40 Hz that have passed through the digital low-pass filter that is the first filter means 34a that filters only the voltage signal having a frequency of 10 Hz or less. The second measurement voltage (frequency band of 10 Hz to 40 Hz) that has passed through the digital bandpass filter, which is the second filter means 34b for filtering only the voltage signal having the frequency, is the first comparison means 36a and the second comparison voltage, respectively. Comparison processing is performed by means 36b. A digital bandpass filter that filters voltage signals in the frequency band of 1 Hz to 5 Hz as the first filter means 34a, and a digital bandpass filter that filters voltage signals in the frequency band of 20Hz to 40Hz as the second filter means 34b. If used, processing of waveform analysis can be performed with higher accuracy.

  The first measurement voltage is compared by the first comparison means 36a to see if it is greater than or equal to a preset distortion threshold value, and when it is greater than or equal to the distortion threshold value, a distortion detection signal indicating this is sent via the relay terminal board 204. The data is output to the main control board 201 and the sub control board 202, respectively. Further, the second measurement voltage is compared by the second comparison means 36b to determine whether it is equal to or higher than a preset threshold for hitting. When the second measured voltage is equal to or higher than the threshold for hitting, a hit detection signal indicating that is applied to the relay terminal board 204. To the main control board 201 and the sub control board 202, respectively. In addition, since the voltage generated by distortion caused by fraud etc. is smaller than the voltage generated by hitting, the threshold values for distortion are smaller, for example, the threshold value for distortion is 100 mV and the threshold value for hitting is 500 mV. Is set. In addition, a normal detection signal that is a constant pulse signal is output from the measurement unit 30 during normal operation. For this reason, when there is a disconnection of the output line from the vibration detection device 1, it can be detected by the fact that the main control board 201 and the sub control board 202 cannot receive the normal detection signal.

  An operation example of the vibration detection apparatus 1 will be shown. When the player inserts a driver or the like between the frame member 110 and the outer frame 123 of the pachinko machine 100, the frame member 110 to which the vibration detection device 1 is fixed is distorted. This distortion distorts the entire iron plate 127 and is conducted to the detection unit 20 of the vibration detection device 1. As a result, a voltage including a frequency band of 0.1 Hz to 10 Hz, which is a frequency characteristic of distortion, is generated from the detection unit 20 in the vibration detection device 1. The voltage is cut by the filter circuit 22 at frequencies other than 0.1 Hz to 50 Hz, and then amplified by the amplifier circuit 24 by about three times and input to the measuring unit 30. The voltage value here is, for example, 100 mV or more at 0.1 Hz to 10 Hz, and 500 mV or less at 10 Hz to 50 Hz.

  The voltage input to the measurement unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and a voltage signal of 0.1 Hz to 10 Hz (first measurement voltage) which is a frequency band of 10 Hz or less is converted by the digital low-pass filter. ) Is filtered. Further, a voltage signal (second measurement voltage) in a frequency band of 10 Hz to 40 Hz is filtered by the digital band pass filter.

  The first measurement voltage is determined by the first comparison unit 36a to determine whether the voltage value is 100 mV or more. Further, it is determined whether the second measured voltage has a voltage value of 500 mV or more by the second comparing means 36b. Since distortion due to the insertion of the driver has occurred, a voltage value of 500 mV or more is not measured by the second comparison unit, but a voltage of 100 mV or more is measured by the first measurement unit. A distortion detection signal is transmitted to the substrate 202.

  Further, when the player performs a sticking action such as strongly hitting the pachinko machine 100, the frame member 110 vibrates. This vibration causes the entire iron plate 127 to vibrate and is conducted to the vibration detection device 1. As a result, a voltage including a frequency band of 10 Hz to 40 Hz, which is a frequency characteristic of hitting, is generated from the detection unit 20 in the vibration detection device 1. The voltage is cut by the filter circuit 22 at frequencies other than 0.1 Hz to 50 Hz, and then amplified by the amplifier circuit 24 by about three times and input to the measuring unit 30. The voltage value here is, for example, 500 mV or more at 10 Hz to 40 Hz, and 100 mV or less at 0.1 Hz to 10 Hz.

  The voltage input to the measuring unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and the digital low-pass filter that is the first filter means 34a has a frequency band of 0.1 Hz to 10 Hz that is a frequency band of 10 Hz or less. The voltage signal (first measurement voltage) is filtered. Further, the voltage signal (second measurement voltage) in the frequency band of 10 Hz to 40 Hz is filtered by the digital band pass filter which is the second filter means 34b.

  The first measurement voltage is determined by the first comparison unit 36a to determine whether the voltage value is 100 mV or more. Further, it is determined whether the second measured voltage has a voltage value of 500 mV or more by the second comparing means 36b. Since vibration is generated by strongly hitting the pachinko machine 100, a voltage value of 100 mV or more is not measured by the first comparison unit 36a, but a voltage of 500 mV or more is measured by the second comparison unit 36b. A hit detection signal is transmitted to the control board 201 and the sub-control board 202.

  Processing performed by the main control board 201 for an illegal act will be described with reference to FIG. First, the main control board 201 detects whether or not there is an input signal from the vibration detection apparatus 1 (step S101). Since the vibration detection device 1 outputs a normal detection signal to the main control board 201 when a fraudulent act is not performed (when a distortion detection signal and a hit detection signal are not transmitted), the main control board 201 is output. If no signal is detected from the vibration detection device 1 in FIG. 5, error detection processing is performed and information is transmitted to the management device (for example, hall computer) via the external terminal board (step S108). This makes it possible to check for disconnection or the like by a store clerk.

  When it is determined that the signal is a normal detection signal when the signal from the vibration detection device 1 is input, the subsequent processing is not performed and it is detected again whether there is an input signal (step S102). If it is determined that the signal from the vibration detection device 1 is not a normal detection signal, it is next determined whether it is a distortion detection signal (step S103). If it is determined that the signal is a distortion detection signal, a game ball launch stop process and a payout stop process are performed (steps S104 and S105). Accordingly, a firing stop command and a payout stop command are sent from the main control device 201 to the prize ball control board 203, and the operations of the launching unit 292 and the payout unit 291 are stopped. At this time, information is transmitted from the main control board 201 to the management device (for example, a hall computer) via the external terminal board. The firing stop process and the payout stop process can be configured to continue until a predetermined period elapses or a recovery process is performed by a store clerk.

  If it is determined in step S103 that it is not a distortion detection signal, it is determined whether or not it is a hit detection signal (step S106). If it is determined that the signal is a hit detection signal, a winning invalidation process is performed (step S107). Thus, while the hit detection signal is detected, control is performed so that even if a game ball enters each entrance, it is not counted.

  If it is determined in step S106 that the signal is not a hit detection signal, it is considered that an unknown signal other than the normal detection signal, the distortion detection signal, and the hit detection signal is input. At this time, error detection processing is performed and an external signal is detected. Information is transmitted to the management device via the terminal board (step S108). As a result, the store clerk confirms that the vibration detection device 1 is malfunctioning or malfunctioning. In addition, although the structure which performs the same error detection process by the case where the signal from the vibration detection apparatus 1 is not input, and the case where an unknown signal is input was shown, it is good also as a different error process, respectively. The main control board 201 may stop the basic operation of the game after the launch stop process and the payout stop process so that signals from the detection units are not input. In this case, fraud can be further prevented by adopting a configuration in which the store clerk recovers.

  In addition, in the case of performing a process for stopping a part or all of the functions of the game after the launch stop process and the payout stop process, the game immediately before the distortion detection signal and the hit detection signal are input to the main control board 201 It is preferable that the state is stored. Thereby, when it is judged that it is not an improper act by the confirmation of the store clerk and the game is restored, the gaming state can be returned to the previous state.

  Next, processing by the sub-control board 202 for fraud will be described with reference to FIG. First, the sub-control board 202 detects whether there is an input signal from the vibration detection device 1 (step S201). When the fraudulent act is not performed from the vibration detection device 1 to the sub control board 202 (when the distortion detection signal and the hit detection signal are not transmitted), a normal detection signal is output. When no signal is detected from the vibration detection device 1 in FIG. 5, an error detection process is performed, an error message is displayed on the symbol display unit 104 and voice notification is performed, or the effect light 111 is blinked by the lamp control board 206, etc. Can be notified. (Step S207).

  When it is determined that the signal is a normal detection signal when the signal from the vibration detection device 1 is input, the subsequent processing is not performed and it is detected again whether there is an input signal (step S202). If it is determined that the signal from the vibration detection device 1 is not a normal detection signal, it is next determined whether it is a distortion detection signal (step S203). When it is determined that the signal is a distortion detection signal, a distortion notification process is performed (step S204). For example, a display indicating that “the door is open” and a sound notification are performed, or notification is performed by blinking the effect light 111 by the lamp control board 206. Thereby, it is possible to notify the store clerk of the game hall that excessive distortion has been applied to the pachinko machine 100, and the store clerk can visit the pachinko machine 100 and perform necessary measures.

  If it is determined in step S203 that it is not a distortion detection signal, it is determined whether or not it is a hit detection signal (step S205). If it is determined that the signal is a hit detection signal, hit detection processing is performed (step S206). This is, for example, a display notification for instructing not to hit the door with the output of an alarm sound, or a notification by blinking of the effect light 111 by the lamp control board 206 or the like. Accordingly, it is possible to notify the store clerk of the amusement hall that an excessive impact has been applied to the pachinko machine 100, so that the store clerk can visit the pachinko machine 100 and perform necessary measures.

  If it is determined in step S205 that the signal is not a hit detection signal, it is considered that an unknown signal other than the normal detection signal, the distortion detection signal, and the hit detection signal is input. At this time, error detection processing is performed. An error message can be displayed on the symbol display unit 104 and voice notification can be performed, or notification by blinking the effect light 111 by the lamp control board 206 can be performed. (Step S207). As a result, the store clerk confirms that the vibration detection device 1 is malfunctioning or malfunctioning. In addition, although the structure which performs the same error detection process by the case where the signal from the vibration detection apparatus 1 is not input, and the case where an unknown signal is input was shown, it is good also as a different error process, respectively.

  In addition, although the example which performs the alerting | reporting by a pachinko machine by a distortion alerting | reporting process (step S204) when a distortion detection signal is output was shown, information is transmitted only to the management apparatus of a pachinko hall without doing this. Anyway. Unlike the dodge that is the target of the tapping detection signal, the barrage that is the target of the distortion detection signal has a strong tendency to perform the goto action continuously for a long time, so only the management device such as a hall computer is notified. It is possible to control by security guards during the goto act. Note that the processing for fraud by the main control board 201 and the sub control board 202 is an example, and the processing may be appropriately changed according to the type of fraud.

  According to the invention shown in the first embodiment, it is determined by one vibration detection device 1 whether the frame member 110 of the pachinko machine 100 is distorted or whether the pachinko machine 100 is hit. Thus, for example, when the frame member is distorted, it is possible to determine that the possibility of squeezing is high. Since it can be determined that the game is high, it is possible to control the gaming machine according to the type of fraud, such as performing a winning invalidation process and hit detection notification.

(Example 2)
The example which used the vibration detection apparatus 1 for the slot machine is shown. 12 and 13 show the configuration of the slot machine. In the slot machine 1001, a front door 1003 having a front mask formed on the front surface is attached so as to be openable and closable by a connecting member that can rotate with respect to an opening of a housing 1002 that is a substantially rectangular box. The front mask is roughly divided into an upper panel portion 1100, a middle panel portion 1200, and a lower panel portion 1300 from the top, and these are integrally formed of a hard plastic designed to enhance visual effects as a decorative board. A tray member 1004 having a tray 1004a for storing medals is provided below the lower panel portion 1300.

  The upper panel portion 1100 has a built-in visual effect lamp (fever lamp) such as an upper lamp or a corner lamp constituted by high-intensity light-emitting diodes (LEDs). The production is appealing to the visual sense of the elderly. In addition, speakers are built in the left and right positions of the upper panel portion 1100, respectively, and a game is produced with sound effects and musical sounds. Further, a liquid crystal display device (not shown) is built in a central position between the left and right speakers.

  The liquid crystal display device displays a moving image that is appropriately selected according to the progress of the game to give a story to the game, and a more dynamic image is displayed in the case of a big game such as a bonus game. , Such as causing the player to expect high dividends.

  An acrylic middle panel 1008 in which a rectangular transparent display window 1008a is formed is attached to the middle middle panel portion 1200. The three reels 1010a, 1010b, and 1010c provided in the housing 1002 can be viewed by the player through the display window 1008a. Below the middle panel 1008, a table-like portion slightly projecting forward is formed, a medal insertion portion 1011 having a medal insertion slot, a bet button 1012, a start lever 1013, three stop buttons 1014a, 1014b, 1014c etc. are arranged.

  When the player inserts medals from the medal insertion unit 1011, up to the maximum number of medals can be stored (credited) in the slot machine 1001. The bet button 1012 is a push-type button switch for presenting the number of medals bet on the game. The start lever 1013 is a lever switch for giving an instruction to rotate the reels 1010a, 1010b, and 1010c all at once. The stop buttons 1014a, 1014b, and 1014c are push-type button switches for individually instructing to stop the rotation of the reels 1010a, 1010b, and 1010c, and are arranged in parallel corresponding to the arrangement of the reels.

  On the lower panel 1015 constituting the lower panel portion 1300 of the front mask, for example, a picture (not shown) of an appearing character is printed and displayed so that the player can recognize the model type of the slot machine 1001 and the like. . The tray member 1004 provided at the lowermost part of the front door 1003 incorporates a medal payout opening 1016 for paying out medals by winning prizes and the like, and a speaker for generating effect sound according to the progress of the game.

  Inside the casing 1002, a main control board 1021, which is a control unit that performs overall control of the overall operation of the slot machine 1001, is attached to the upper position of the casing 1002. The main control board 1021 is a microcomputer-based control circuit board on which electronic components such as an interface circuit having a matching function when communicating with a CPU, ROM, RAM, and other peripheral devices are mounted, and is housed in a transparent board case. The housing 1002 is fixed so as not to be detached.

  Near the center of the housing 1002, a reel unit 1010 in which three reels 1010a, 1010b, and 1010c are arranged in parallel in the axial direction is opposed to the display window 1008a formed on the front door 3 side. The frame 1022 is fixed. A reel device substrate (not shown) is attached to the upper portion of the reel unit 1010. The spinning device substrate outputs a drive pulse signal that is current-amplified based on the pulse data from the main control substrate 1021 to the stepping motors of the reels 1010a, 1010b, and 1010c, thereby controlling the rotation and stop of each reel. It is carried out.

  In the space below the reel unit 1010, a medal payout device 1023 for releasing medals at the time of a prize payout or the like is installed. The medal payout device 1023 stores medals inserted into the medal insertion unit 1011 in the hopper unit 1023a, and releases a medal stored in the hopper unit 1023a when receiving a payout command signal for instructing to pay out medals from the main control board 1021. It is discharged to the outside through the slit 1023b. The discharge slit 1023b is provided with a payout sensor 1063, which detects the medals released one by one and outputs them to the main control board 1021. As a result, the main control board 1021 can perform control for paying out the required payout number (command payout amount) based on the payout command signal while counting the released medals.

  On the side of the medal payout device 1023, there are an overflow tank 1024 for storing medals overflowing from the hopper 1022a, and a main power supply device 1025 for distributing required power to each device built in the slot machine 1001. is set up.

  Further, the side plate adjacent to the main control board 1021 transmits a signal indicating a gaming state such as a jackpot in the slot machine 1001 and an operating state such as insertion / payout of medals to an external management device (for example, a hall computer). An external concentration terminal board 1026 is attached.

  The front door 1003 has a front mask integrally formed of relatively hard plastic as a main frame, and has a horizontal frame 1311 and a vertical frame 1312 which are long sheet metal members at the upper end and both left and right ends on the back side. , 1313 are fixed with screws. An upper panel assembly 1032 incorporating an LED substrate, a speaker, a liquid crystal display device, and the like on which a light emitting diode (LED) as a light source such as the upper lamp and the corner lamp described above is mounted is attached to the upper part on the back side of the front door 1003. Yes. Further, a sub-control board 1033 for driving the upper panel assembly and mainly performing control related to game effects is attached.

  Below the sub-control board 1033, an intermediate panel 1008 having a transparent display window 1008 a is provided on the front surface, and a cold cathode fluorescent tube 1034 that irradiates the outer peripheral surfaces of the reels 1010 a, 1010 b, and 1010 c, and a picture of the intermediate panel 1008 A lamp house unit in which a plurality of lamps 1035 and 1035 for lighting display and a central display board 1036 for relaying outputs of switches such as a start lever 1013 and stop buttons 1014a, 1014b and 1014c to the main control board 1021 are assembled. 1037 is attached.

  A medal selector 1038 is attached below the lamp house unit 1037. The medal selector 1038 is provided to determine whether the medal inserted in the medal insertion unit 1011 on the front is correct or not, and to count the number of regular medals inserted. That is, when the medal selector 1038 determines that the inserted medal is genuine, the medal is passed to the medal storage guide 1039 side, and the medal sensor, which is an optical sensor, detects the medal and goes to the main control board 1021. The input signal is output. Therefore, if the medal selector is illegally operated, there is a possibility that an unjust medal will be paid out. The medal storage guide 1039 guides and stores the regular medals passed by the medal selector 1038 to the hopper portion 1023a of the medal payout device 1023 on the housing 1002 side.

  A lower panel unit 1040 in which the lower panel 1015 and the like are unitized is attached below the medal selector 1038. In addition, the medal payout opening 1016 of the front door 1003 communicates with the cancel chute 1041 for guiding the medal or foreign matter determined to be inappropriate by the medal selector 1038 to the front tray 1004a, and the medal payout outlet 1016. A payout chute 1042 that guides the medals discharged by the payout device 1023 and pays it out to the tray 1004a is provided on the back side of the lower panel unit 1040. Further, below the lower panel unit 1040, speakers 1044a and 1044b facing the sound emitting units 1017a and 1017b on the front surface are attached.

  The vibration detection device 1 is screwed to the central portion (portion shown in FIG. 14B) of the horizontal frame 1311 provided on the back side of the front door 1003 in a state of being enclosed in the case 40. By fixing the vibration detection device 1 to the hard plate-like member provided over a wide range as described above, vibration generated in the slot machine 1001 is easily transmitted to the vibration detection device 1. A main control board 1021 is connected to the output side of the vibration detection device 1, and performs processing for fraud in accordance with a signal from the vibration detection device 1.

  In the present embodiment, the vibration detection device 1 causes the player to open the front door 1003 and illegally operate the medal selector 1038 (illegal act) and to act that may damage the slot machine 1001 by hitting it strongly. (Damaged behavior) is detected at the same time. Here, when a temporal external force such as distortion due to fraud is applied, a voltage having a frequency band of 0.1 Hz to 10 Hz, particularly a voltage of 1 Hz to 5 Hz, is characteristically generated in the detection unit 20. In addition, when a momentary impact such as a beating due to a damaging action is applied, a voltage having a frequency of 10 Hz or more is characteristically generated in the detection unit 20. Note that the frequency of the voltage generated from the detection unit 20 due to the vibration of the reels and the like generated during the game is characteristic at several kHz.

  Since the configurations of the filter circuit 22 and the amplifier circuit 24 are the same as those in the first embodiment, a description thereof will be omitted. In the measurement unit 30, the distortion threshold is 200 mV and the tapping threshold is 800 mV, which is larger than the setting for the pachinko machine 1. In the slot machine 1001, the act of hitting, such as hitting the slot button 1014 to stop the reel, is performed on a daily basis, and if a vibration caused by this is detected, it will interfere with normal games. Therefore, the hitting threshold is set large. Further, since the voltage generated when the front door 1003 is pry open is larger than the voltage generated when the frame member 110 of the pachinko machine 1 is distorted, the distortion threshold is set large. Since the configuration of the measuring unit 30 other than this is the same as that of the first embodiment, a description thereof will be omitted.

  An operation example of the vibration detection apparatus 1 will be shown. When the player tries to open the front door 1003 of the slot machine 1001, the horizontal frame 1311 to which the vibration detection device 1 is fixed is distorted. As a result, a voltage including a frequency band of 0.1 Hz to 10 Hz, which is a frequency characteristic of distortion, is generated from the detection unit in the vibration detection device 1. The voltage is cut by the filter circuit 22 at frequencies other than 0.1 Hz to 50 Hz, and then amplified by the amplifier circuit 24 by about three times and input to the measuring unit 30. The voltage value here is, for example, 200 mV or more at 0.1 Hz to 10 Hz, and 800 mV or less at 10 Hz to 50 Hz.

  The voltage input to the measuring unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and the digital low-pass filter that is the first filter means 34a has a frequency band of 0.1 Hz to 10 Hz that is a frequency band of 10 Hz or less. A voltage signal (first measurement voltage) is extracted. Further, a voltage signal (second measurement voltage) in the frequency band of 10 Hz to 40 Hz is extracted by a digital bandpass filter which is the second filter means 34b.

  The first measurement voltage is determined by the first comparison means 36a whether the voltage value is 200 mV or more. Further, it is determined whether the second measured voltage has a voltage value of 800 mV or more by the second comparing means 36b. Since the slot machine 1001 is greatly distorted, a voltage of 200 mV or higher is measured by the first measuring unit, and thus a distortion detection signal is transmitted to the main control board 1021 and the sub control board 1033.

  Further, when the player hits the slot machine 1001 strongly, the vibration is transmitted to the horizontal frame 1311 on which the vibration detection device 1 is fixed. As a result, a voltage including a frequency band of 10 Hz to 40 Hz, which is a frequency characteristic of hitting, is generated from the detection unit in the vibration detection device 1. The voltage is cut by the filter circuit 22 at frequencies other than 0.1 Hz to 50 Hz, and then amplified by the amplifier circuit 24 by about three times and input to the measuring unit 30. The voltage value here is, for example, 800 mV or more at 10 Hz to 40 Hz, and 200 mV or less at 0.1 Hz to 10 Hz.

  The voltage input to the measurement unit 30 is converted into a digital voltage signal by the A / D conversion means 32, and a voltage signal of 0.1 Hz to 10 Hz (first measurement voltage) which is a frequency band of 10 Hz or less is converted by the digital low-pass filter. ) Is extracted. Further, a voltage signal (second measurement voltage) in a frequency band of 10 Hz to 40 Hz is extracted by the digital band pass filter.

  The first measurement voltage is determined by the first comparison means 36a whether the voltage value is 200 mV or more. Further, it is determined whether the second measured voltage has a voltage value of 800 mV or more by the second comparing means 36b. Since vibration is generated by hitting the slot machine 1001 strongly, a voltage of 800 mV or more is measured by the second comparison unit 36b, and a hit detection signal is transmitted to the main control board 1021 and the sub control board 1033. The

  The basic processing by the main control board 1021 and the sub control board 1033 for fraud is the same as in the first embodiment. When a distortion detection signal is detected, the main control board 1021 stops paying out medals. The control board 1033 notifies that the front door is open. When a hit detection signal is detected, the main control board 1021 stops paying out medals, and the sub-control board 1033 notifies that the slot machine 1001 is not strongly hit. Note that the processing for fraud by the main control board 1021 and the sub control board 1033 is an example, and the processing may be appropriately changed according to the type of fraud.

As described above, the embodiments of the present invention have been described in detail with reference to the drawings.

For example, the gaming machine is not limited to a ball game machine or a revolving game machine, and includes various gaming machines such as a crane game and a poker game. Moreover, the frequency band of the voltage compared with the threshold value by the measurement unit can be appropriately determined depending on the type of the target gaming machine. Moreover, you may make each function of a measurement part independent from a vibration detection apparatus. In this case, a measuring unit may be newly provided, or a control board such as a relay terminal board or a main control board may have the function.
