Description

  The present invention relates to a gaming machine capable of preventing unauthorized gaming.

  A gaming machine such as a pachinko machine is provided with an operation handle for receiving an operation input by a player. A game ball is fired in response to the player's operation input to the operation handle. After rising from below and reaching the upper position, it falls in the game area. The player always adjusts the operation lever as the firing instruction member provided on the operation handle so that the falling game ball enters the desired winning opening on the game board. Further, the operation handle is provided with a touch sensor, and the game ball can be launched only when the player is in contact with the operation handle by hand.

  Further, the operation handle is provided with a biasing means such as a coil spring so that the operation lever automatically returns to a reference position (a position where no firing is performed) when the player's operation is completed. For this reason, some players insert foreign objects such as game balls, coins, paper, etc. into the gap formed between the operation lever and the cap, etc., and fix the operation lever at substantially the same position. There is a person who performs a so-called “fixed hit” in which a game ball is continuously fired at an arbitrary position in a game area desired by the player only by touching the operation handle without gripping the handle. The act of inserting foreign matter into the gap formed in the operation handle described above promotes the deterioration of the constituent members of the operation handle, causing a failure of the operation handle.

Accordingly, a technique is disclosed that includes groove depth displacement means for displacing the depth of the gap of the operation handle as an operation handle of a gaming machine that can suppress the insertion of foreign matter and reduce the occurrence of damage or failure (for example, Patent Document 1). The groove depth displacing means includes an axial double-action device having a pressing member that double-acts in the direction of the rotation axis of the operation lever, and a radial direction in which the groove depth is reduced by receiving the pressing force of the pressing member. When the operation lever is fixed by an insert (foreign matter), the insert is pushed out by the extension that works in conjunction with the axial double-acting device, and the operation lever is inserted. It can be released from the fixed state.
JP 2008-245967 A

  However, in the technique of the above-mentioned Patent Document 1, if the foreign matter inserted in the groove formed between the movable portion (operation lever) and the fixed portion does not easily change in shape such as a coin or a game ball, the movable portion However, when the shape of gum, clay, etc. changes easily and something with adhesive force is inserted, the expansion part cannot push out the foreign material, and the movable part is fixed. “Fixed” is possible.

  In view of such problems, the present invention reliably detects whether or not the player is actually holding the operation handle, and fires the game ball only when the player holds the operation handle. It is to propose a gaming machine capable of preventing fixing.

  In order to solve the above-described problems, a gaming machine according to the present invention is configured to play a game ball with an operation handle provided with a firing instruction member provided so as to be rotatable and a hitting force according to a rotation angle of the firing instruction member. A launching unit that fires upward, a touch sensor that is provided on the operation handle and detects whether or not a player is in contact with the operation handle, and is provided on the operation handle and applied to any part of the operation handle. Detecting means for converting a change in pressure into a voltage signal, and a first frequency indicating that a continuous strain is applied to an arbitrary part of the operation handle from the voltage signal output from the detecting means. Based on the first filter means for extracting the band component, the detection result by the touch sensor, and the voltage signal of the first frequency band component output from the first filter means, Characterized in that it and a game ball launch control means for controlling.

  When an external force applied by the player is applied to the detecting means such as a piezoelectric element, the vibration of the detecting means varies depending on the type (applying method) of the external force, and the frequency characteristics of the voltage signal generated accordingly vary. Here, by extracting the first frequency band component as the predetermined frequency band component from the voltage signal of the detection means, the type of the external force can be specified, and the game ball can be fired based on the voltage signal. Become. In other words, the first filter means extracts the frequency band component indicating that continuous “distortion” has been added as the first frequency band component, so that the continuation caused by the player's grip on the operation handle is continued. Can be detected reliably.

  The game ball launch control means detects a player's contact with the operation handle by a touch sensor, and the voltage signal of the first frequency band component output from the first filter means satisfies a predetermined first condition. The launching of the game ball by the launching unit may be permitted.

  Thus, when the touch sensor detects a contact of the player with the operation handle and the voltage signal output from the first filter means satisfies the predetermined first condition, that is, the player actually holds the operation handle. Only when it is held, the launch of the game ball by the launching unit can be permitted in accordance with the player's operation input to the operation handle, and the operation handle can be prevented from being fixed.

  Only one of the touch sensor detects the player's contact with the operation handle or the voltage signal of the first frequency band component output from the first filter means satisfies a predetermined first condition. In this case, an abnormality handling means for performing an abnormality handling process for dealing with a gaming ball launch abnormality by the operation handle may be further provided.

  With this configuration, the touch sensor detects contact of the player with the operation handle, but the voltage signal output from the first filter means does not satisfy the predetermined first condition, that is, is formed on the operation handle. Even when the operation handle is fixed by inserting a foreign object in the gap and the game ball is fired by bringing a finger or the like into contact with the operation handle, the abnormality handling process can be performed.

  A second frequency band component having a frequency band higher than the first frequency band component indicating that an instantaneous impact is applied to an arbitrary part of the gaming machine is extracted from the voltage signal output from the detection means. Two filter means, a second detection signal output means for outputting a second detection signal when the voltage signal output from the second filter means satisfies a predetermined second condition, and a second output from the second detection signal output means. 2 may further include fraud countermeasure execution means for performing fraud countermeasure processing for responding to fraudulent acts on the gaming machine in response to the two detection signals.

  Here, for example, when an external force is gradually applied like “distortion”, a voltage signal having a relatively low frequency is generated, and when an external force is momentarily applied like “impact”, a comparison is made. A voltage signal with a high frequency is generated.

  Therefore, by extracting each of multiple frequency band components of the voltage signal output from the detection means, it is possible to check which frequency band the voltage signal is biased to and specify the type of external force corresponding to the biased frequency band It becomes possible to do. For example, if it is biased toward a low first frequency band component, it can be determined that “distortion” has been applied, and if it is biased toward a high second frequency band component, it can be determined that “impact” has been applied. Therefore, when the “impact” is detected, the configuration including the fraud countermeasure executing means for performing the fraud countermeasure processing for responding to the fraudulent act on the gaming machine, the “impact” is improperly applied to the gaming machine such as “Dotsuki”. When given, it is possible to perform fraud countermeasure processing.

  The predetermined first condition and the second condition may be that the maximum value or integrated value of the voltage signal of each of the first frequency band component and the second frequency band component is equal to or greater than a predetermined threshold, and the predetermined first condition May be that the voltage signal of the first frequency band component continues for a predetermined time or more.

  In the present invention, depending on the type of action to be discriminated, the maximum value is determined when the maximum value of the frequency band component of each voltage signal can be determined as “distortion” or “impact” even when the maximum value exceeds a predetermined threshold even once. The integrated value is used when it is appropriate to determine the amount of vibration of the frequency band component of the voltage signal, and the duration is used when it is appropriate to determine “distortion” based on the continuity of the voltage signal. With such a configuration, it is possible to reliably grasp the action and perform appropriate processing under conditions according to the type of external force.

  The detection means may be constituted by a unimorph piezoelectric element or a bimorph piezoelectric element.

  Each of the unimorph piezoelectric element and the bimorph piezoelectric element is small, has a wide frequency band, and has low noise. By using such a piezoelectric element, vibrations in various frequency bands can be detected.

  As described above, in the present invention, the player's contact with the operation handle is detected by the touch sensor, the external force applied to the operation handle is converted into voltage by the detection means, and the voltage signal is a signal having a predetermined frequency band component. As a result, it is possible to perform appropriate processing (game ball launch processing and abnormality response processing) according to the action by reliably grasping the external force (for example, “distortion”) corresponding to such a frequency band. It becomes. Therefore, abnormal fixation of the operation handle can be prevented by firing the game ball only when the player is holding the operation handle.

  The best mode for carrying out the present invention will be described below with reference to the drawings. For convenience, unless otherwise noted, parts having substantially the same operational effects are denoted by the same reference numerals, and the description thereof is omitted. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified.

  A gaming machine, for example, a pachinko machine, is provided with an operation handle for adjusting the hitting force of a launching unit that hits a game ball and launches it on a game area (game board). Such an operation handle is provided with a biasing means such as a coil spring so that the operation lever automatically returns to a reference position (a position where no firing is performed) when the operation by the player is completed. Therefore, when the player attempts to fire the game ball, the player plays the game while supporting the operation lever against the urging force of the urging means. However, some players take care of supporting the operation lever and perform so-called “fixed hitting”. The act of inserting a foreign object into the gap formed in the operation handle in such “fixed driving” destroys the constituent members of the operation handle and causes a failure of the operation handle.

  In the embodiment of the present invention, it is detected whether or not the player is grasping the operation handle, and the game ball is fired only when the player is grasping, thereby preventing a fixed hit by the player. It proposes a possible gaming machine. Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

In the present embodiment, the metal plate 162 is formed in a circular shape having a diameter of about 12 mm and has a thickness of about 0.1 mm.

  The function of the vibration sensor 170 will be described with reference to FIG. In the vibration sensor 170, when the metal plate 162 is bent in the direction shown in FIG. 8A and the piezoelectric element 160 is extended in the radial direction, the metal plate 162 is bent in the direction shown in FIG. Since the application direction of the generated voltage is reversed between when the metal plate is contracted in the radial direction, the bending of the metal plate 162 is caused by the vibration sensor 170 receiving the vibration of the external force and the state shown in FIG. ) Are alternately repeated to generate an alternating voltage having a frequency corresponding to the vibration. Therefore, it is possible to determine how the vibration sensor 170 is vibrating by measuring the voltage generated by the vibration sensor 170. Since the vibration sensor 170 uses the amount of change in bending as a voltage signal, the output converges to 0 regardless of the distortion at that time when the change disappears.

  FIG. 9 shows a functional block of the vibration detection device 150, and FIG. 10 shows an assembly diagram of the vibration detection device 150. As shown in FIG. 10, the vibration sensor 170 has a metal plate 162 side bonded to a circuit board 164 such as a glass epoxy board. As shown in FIG. 9, the circuit board 164 has a filter circuit 172 for cutting noise components from the voltage signal generated in the vibration sensor 170, an amplifier circuit 174 for amplifying the voltage signal that has passed through the filter circuit 172, A measurement unit 180 that measures the voltage of the voltage signal amplified by the amplifier circuit 174 and an output connector 178 that outputs a measurement result from the measurement unit 180 are provided.

  As described above, by integrally providing the vibration sensor 170, the filter circuit 172, the amplifier circuit 174, and the measuring unit 180 on the same circuit board 164, the vibration detection device 150 can be formed in a compact manner. Note that lead wires (not shown) are respectively attached to the electrode 160 b on the surface side of the vibration sensor 170 and the metal plate 162, and these lead wires are connected to be input to the filter circuit 172. For the adhesion of the vibration sensor 170, it is possible to suppress the vibration from being absorbed by the elasticity of the adhesive by using a material having a high hardness after adhesion such as an epoxy adhesive.

  The filter circuit 172 is configured by, for example, a capacitor and a resistor, and cuts frequency components (noise) that are not necessary for measurement, and filters only frequency components necessary for measurement. In the present embodiment, a combination of a high-pass filter and a low-pass filter or a band-pass filter is used, and thereby components not required for measurement can be cut from the voltage signal generated by the vibration sensor 170.

  The amplifier circuit 174 is configured using, for example, an operational amplifier and a resistor. The voltage amplification factor of the amplification circuit 174 can be changed as appropriate. When the voltage generated in the vibration sensor 170 is high depending on the attachment target and attachment position of the vibration sensor 170, the voltage amplification factor is not so large, for example, 3 When the voltage generated by the vibration sensor 170 is low, the voltage amplification factor can be increased to, for example, about 20 times.

  The measurement unit 180 converts an input analog voltage signal into a digital voltage signal, and converts a voltage signal in a frequency band to be measured from the voltage signal converted by the A / D converter 182. It comprises a digital filter as a plurality of filter means 184 for filtering, and a plurality of detection signal output means 186 for comparing the maximum value of the voltage signal filtered through the digital filter with a predetermined threshold value and outputting a comparison result. The detection signal output means 186 extracts a plurality of types of frequency band components from the input voltage signal, and determines whether or not the voltage signals of the extracted frequency band components exceed a predetermined threshold value. The measurement unit 180 is, for example, a ROM that stores programs that implement the functions of the plurality of filter units 184 and the detection signal output unit 186, a CPU that executes arithmetic processing based on the programs stored in the ROM, and the arithmetic processing of the CPU It is composed of a RAM functioning as a data work area and a one-chip microcomputer having an A / D conversion function.

  For example, when measurement is performed for two types of frequency bands among a plurality of assumed frequency bands, the first filter means of the present invention is applied to the voltage signal input to the measurement unit 180 and subjected to A / D conversion. The first frequency band component voltage signal filtered by the first digital filter 184a is monitored by the first detection signal output means 186a, which is one of the detection signal output means 186, and the pass frequency band is higher than that of the first digital filter 184a. The voltage signal of the second frequency band component filtered by the second digital filter 184b as the second filter means of the present invention is monitored by the second detection signal output means 186b which is another detection signal output means 186. The processing performed by the above-described one-chip microcomputer or the like corresponds to the first digital filter 184a, the second digital filter 184b, the first detection signal output unit 186a, and the second detection signal output unit 186b of this embodiment. To do.

  When the voltage signal output from the first digital filter 184a satisfies the predetermined first condition, that is, when the maximum value of the voltage signal exceeds a predetermined threshold, the first detection signal output means 186a operates the operation handle 113. A first detection signal indicating that continuous distortion has been applied is output. The second detection signal output means 186b operates the operation handle 113 when the voltage signal output from the second digital filter 184b satisfies a predetermined second condition, that is, when the maximum value of the voltage signal exceeds a predetermined threshold. A second detection signal indicating that an impact has been applied to any part of the pachinko machine 100 including Thus, when the maximum value of the frequency band component of the voltage signal exceeds the predetermined threshold even once, it can be determined as “distortion” or “impact”.

  As described above, when an external force is applied to the vibration sensor 170 using a piezoelectric element or the like, the vibration of the vibration sensor 170 varies depending on the type of external force (how it is applied), and the frequency characteristics of the voltage signal generated accordingly vary. It becomes. For example, when a continuous external force is gradually applied like the “distortion” described above, a voltage signal with a relatively low frequency is generated, and when an external force is momentarily applied like an “impact”. Generates a voltage signal having a relatively high frequency. As described above, in this embodiment, different events such as “distortion” and “impact” can be detected by one detection means, so that cost and load can be reduced. The arrangement restriction of the members can be minimized.

  Therefore, by extracting each of a plurality of frequency band components of the voltage signal output from the vibration sensor 170, it is possible to check which frequency band the voltage signal is biased to, and to select the type of external force corresponding to the biased frequency band. It becomes possible to specify. For example, if it is biased toward a low first frequency band component, it can be determined that “distortion” has been applied, and if it is biased toward a high second frequency band component, it can be determined that “impact” has been applied.

  Here, the predetermined first condition and the second condition used in the first detection signal output means 186a and the second detection signal output means 186b are that the maximum value of the voltage signal of each frequency band component exceeds a predetermined threshold value. However, the integrated value of the voltage signal of each frequency band component may exceed a predetermined threshold. Regarding the predetermined first condition, the duration of the voltage signal of the first frequency band component may exceed a predetermined threshold. Here, the integrated value indicates the total amount of voltage signals such as an integral value, a square integral value, a square mean, etc., of each frequency band component during a predetermined time.

  In the present embodiment, when the maximum value of the frequency band component of the voltage signal exceeds the predetermined threshold even once, it can be determined as “distortion” or “impact”, and the maximum value is used to determine the frequency band component of the voltage signal. The integrated value is used when it is appropriate to determine the amount of vibration, and the duration is used when it is appropriate to determine “distortion” based on the continuity of the voltage signal. With such a configuration, it is possible to reliably grasp the action and perform appropriate processing under conditions according to the type of external force.

  Further, the first detection signal output means 186a and the second detection signal output means 186b transmit the first detection signal and the second detection signal as discrete signals, and the value is a binary number in a predetermined format or PWM (Pulse Width Modulation). Represented by Also, the levels of the first detection signal and the second detection signal can be shown in a plurality of stages. When the levels of the first detection signal and the second detection signal are indicated in a plurality of stages, the first detection signal and the second detection signal may be output to the winning ball control board 203 through an output line provided for each of the plurality of stages. Then, it may be output superimposed on one output line.

  In the present embodiment, the first digital filter 184a, the second digital filter 184b, the first detection signal output means 186a, and the second detection signal output means 186b are integrally installed as the vibration detection device 150, The prize ball control board 203 is configured to use the first or second detection signal output from the vibration detection device 150. However, the present embodiment is not limited to such a case. For example, the prize ball control board A filter unit and a detection signal output unit may be installed in 203 respectively.

  Even when a voltage signal equal to or higher than the threshold value is not observed, a predetermined signal is always output from the measurement unit 180. Therefore, when an improper operation such as disconnection of the output line from the vibration detection device 150 is performed. In this case, the disconnection or the like can be detected at the output destination of the vibration detection device 150 when no signal can be received.

  FIG. 11 and FIG. 12 show changes over time in the voltage generated in the vibration sensor 170 when an external force is applied to the vibration detection device 150, respectively. FIG. 11 shows a so-called “distortion” waveform when an external force is applied at a low frequency so as to gradually distort, and FIG. 12 shows a so-called “impact” waveform when an external force is instantaneously applied at a high frequency. Is shown. Here, in the case of distortion, a voltage signal having a relatively low frequency of 0.1 Hz to 10 Hz, particularly a voltage signal having a frequency band of 1 Hz to 5 Hz is generated. In the case of an impact, a voltage signal having a relatively high frequency of 10 Hz to a predetermined frequency (for example, 1 kHz), particularly a voltage signal having a frequency band of 20 Hz to 40 Hz is generated.

  Therefore, for example, when grasping that an external force such as strain and impact has been applied, the frequency band that the first digital filter 184a filters is set to 0.1 Hz to 10 Hz, and the frequency that the second digital filter 184b filters. The band may be set to 10 Hz to a predetermined frequency. When it is desired to discriminate between distortion and impact with higher accuracy, the frequency band filtered by the first digital filter 184a is 1 Hz to 5 Hz, and the frequency band filtered by the second digital filter 184b is 20 Hz to 40 Hz. You only have to set it.

  As described above, when the detection signal output means 186 is provided separately, the voltage signals obtained by filtering the first digital filter 184a and the second digital filter 184b are output as they are (or D / A converted) separately. Then, for example, detection signal output means (first detection signal output means 186a, second detection signal output means 186b) provided on the prize ball control board 203, which is an output destination, may determine whether the threshold value has been exceeded. In this case, since some voltage such as noise is always output, it is not always necessary to output a constant signal for detecting disconnection or the like as described above.

  In addition, although an example in which a plurality of filter units 184 are provided in the measurement unit 180 is shown here, as another example, a voltage signal generated by the vibration sensor 170 is directly branched, and a first digital filter (band) is provided for one of them. Pass filter 184a is passed through the second digital filter (band pass filter) 184b with respect to the other to obtain voltage signals of two types of frequency band components separately, and the detection signal output means (first filter) 1 detection signal output means 186a and second detection signal output means 186b) may be provided to determine whether the threshold value has been exceeded.

  As shown in FIG. 10, the circuit board 164 to which the vibration sensor 170, the filter circuit 172, the amplifier circuit 174, and the measuring unit 180 are fixed is fitted into a box part 191 formed of, for example, a plastic or the like, and a box part 191. It is covered with a case 190 including a lid portion 195 to be joined.

  Through holes 164a and 164b are respectively provided in the corners on the diagonal line of the circuit board 164. The box part 191 and the lid part 195 also have through holes 191a and 191a in portions corresponding to the through holes 164a and 164b of the circuit board 164. 191b, 195a, 195b are provided. The through holes 191a and 191b on the box portion 191 side are drilled in the center of the columnar portions 192a and 192b protruding upward from the bottom surface of the box portion 191, and the through holes 195a and 195b on the lid portion 195 side are the back side of the lid portion 195. Is drilled in the center of the columnar portions 196a, 196b projecting downward from the center.

  Thus, when the circuit board 164 is covered by the case 190, the circuit board 164 is sandwiched between the columnar portions 192a and 192b of the box portion 191 and the columnar portions 196a and 196b of the lid portion 195. Moreover, since the through-holes 195a, 164a and 191a penetrate and the through-holes 195b, 164b and 191b penetrate, they can be fixed diagonally with two screws. The box portion 191 is provided with a through hole 197 at a position corresponding to the output connector 178 provided on the circuit board 164.

  By covering the vibration sensor 170 with the case 190 in this manner, the vibration sensor 170 is blocked from the outside by the case 190, so that external air does not affect the vibration sensor 170. When the case 190 is not used, potting with an epoxy resin or the like is preferably performed so as to cover the vibration sensor 170 so as not to be affected by air. In addition, you may cover the potted thing with the case 190, and the influence by air can further be reduced in this case.

  The vibration detection device 150 covered by the case 190 may be attached to the object by bonding the case 190 and the object, for example, the internal mounting plate of the operation handle 113 of the pachinko machine 100, The case 190 and the circuit board 164 are preferably screwed directly to the object (internal mounting plate) through a through hole provided in the case 190 and the circuit board 164. When the circuit board 164 is sandwiched between the box part 191 and the lid part 195, the vibration and distortion of the object are conducted to the circuit board 164 through the case 190. Since vibration is directly conducted from the screw to the circuit board 164 and is not accompanied by deterioration in detection accuracy due to elasticity of an adhesive or the like, the applied external force can be accurately captured and the type of external force can be distinguished with high accuracy.

  Moreover, although the case where it measured about two types of frequency bands was shown here, it is not restricted to this, It can also measure about three or more types of frequency bands. In this case, for example, the number of filter means 184 and detection signal output means 186 is increased.

  Further, although the unimorph piezoelectric element has been described as an example of the piezoelectric element 160, the present invention is not limited to this, and a bimorph piezoelectric element can also be used. Such 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.

  Each of the unimorph piezoelectric element and the bimorph piezoelectric element is small, has a wide frequency band, and has low noise. By using such a piezoelectric element, vibrations in various frequency bands can be detected.

  Next, functions and operations when the above-described vibration detection device 150 is applied to the operation handle 113 of the pachinko machine 100 will be described.

  In the present embodiment, the vibration detection device 150 simultaneously detects “distortion” caused by the player's grip on the operation handle 113 and “impact” such as “undock” such as an improper pressure applied to the pachinko machine 100. can do. Here, when an external force in a low frequency band, which is distortion caused by the player holding the operating handle 113, is applied, the vibration sensor 170 has a voltage signal having a frequency band of 0.1 Hz to 10 Hz, particularly 1 Hz to 5 Hz. A voltage signal is characteristically generated. In particular, when the player holds the operation handle 113 properly, the magnitude of the “distortion” slightly changes due to the respiration (microvibration) of the human player. This change in the magnitude of distortion due to respiration produces a characteristic low frequency band wave. Therefore, it is possible to determine whether or not the player is properly holding the operation handle 113 by detecting the specific wave change caused by the breathing.

  In addition, when an external force in a high frequency band of impact due to a sticking or the like is applied, a voltage signal having a frequency band of 10 Hz to a predetermined frequency, particularly a voltage signal of 20 Hz to 40 Hz, is characteristically generated in the vibration sensor 170. It should be noted that the frequency of the voltage generated from the vibration sensor 170 due to the vibration of the game ball generated during the game, the vibration of the launching portion 239, the vibration of the variable winning device (opening / closing door 109a), and the vibration of the effect actors 115 and 116. Since both appear characteristically at several kHz, the influence on the first detection signal and the second detection signal can be avoided by selecting a frequency equal to or lower than the predetermined frequency, for example, 1 kHz. Hereinafter, the configuration of the vibration detection device 150 will be described in detail.

  The filter circuit 172 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, a frequency band (0.1 Hz to 10 Hz) for detecting distortion and the like from a voltage output from the vibration sensor 170 and a frequency band (10 Hz to a predetermined frequency (for example, 50 Hz in this embodiment) for detecting an impact and the like. Can be filtered only in the frequency band from 0.1 Hz to 50 Hz, and other noise components including a voltage generated by vibration of a game ball or the like can be cut. The amplifier circuit 174 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 172 is amplified and input to the measuring unit 180.

  In the measurement unit 180, the input voltage in the frequency band from 0.1 Hz to 50 Hz is first A / D converted from an analog voltage to a digital voltage signal by the A / D converter 182. Next, the first detection signal (frequency band of 0.1 Hz to 10 Hz) that has passed through the digital low-pass filter that is the first digital filter 184a that filters only the voltage signal having a frequency of 10 Hz or less and the frequency of 10 Hz to 50 Hz are obtained. The second detection signal (frequency band of 10 Hz to 50 Hz) that has passed through the digital band-pass filter, which is the second digital filter 184b that filters only the voltage signal having, is the first detection signal output means 186a and the second detection signal output, respectively. Comparison processing is performed by means 186b. The first digital filter 184a is a digital band-pass filter that filters voltage signals in the frequency band of 1 Hz to 5 Hz, and the second digital filter 184b is a digital band-pass filter that filters voltage signals in the frequency band of 20 Hz to 40 Hz. If used, processing of waveform analysis can be performed with higher accuracy.

  The voltage signal filtered by the first digital filter 184a is compared with a threshold value for distortion set in advance by the first detection signal output means 186a, and when it is equal to or higher than the threshold value for distortion, the game ball firing control means A first detection signal indicating that the operation handle 113 is distorted is output to the prize ball control board 203 in order to permit the launching part 239 to launch a game ball. Further, the voltage signal filtered by the second digital filter 184b is compared with a threshold value for impact set in advance by the second detection signal output means 186b, and if it is equal to or more than the threshold value for impact, the pachinko machine 100 can be arbitrarily selected. A second detection signal indicating that an instantaneous external force (impact) is applied to the part is output to the winning ball control board 203.

  In addition, since the voltage generated by the impact caused by the fraud etc. is larger than the voltage generated by the distortion or the like, the impact threshold is set larger, for example, the impact threshold is 500 mV and the strain threshold is 100 mV. In addition, since a normal detection signal, which is a constant pulse signal, is output from the measurement unit 180 in the normal state, in the case where fraud such as disconnection of the output line from the vibration detection device 150 is performed, the prize ball control board When the normal detection signal cannot be received in 203, disconnection or the like can be detected.

  Here, an operation example of the vibration detection device 150 is shown. When the player actually grips the operation handle 113, vibration due to the grip is conducted to the operation handle 113 to which the vibration detection device 150 is fixed. As a result, a voltage signal including a frequency band of 0.1 Hz to 10 Hz, which is a frequency characteristic of distortion, is generated from the vibration sensor 170 in the vibration detection device 150. The voltage signal is cut by the filter circuit 172 at a frequency other than 0.1 Hz to 50 Hz, and then amplified by the amplification circuit 174 by about three times and input to the measuring unit 180. The voltage value here is, for example, 500 mV or less at 10 Hz to 50 Hz, and 100 mV or more at 0.1 Hz to 10 Hz.

  The analog voltage signal input to the measurement unit 180 is converted into a digital voltage signal by the A / D converter 182 and is 0.1 Hz which is a frequency band of 10 Hz or less by the digital low-pass filter (first digital filter 184a). A voltage signal (first detection signal) in the frequency band of 10 Hz is extracted. Further, a voltage signal (second detection signal) of 10 Hz to 50 Hz is extracted by the digital bandpass filter (second digital filter 184b).

  The first detection signal is determined by the first detection signal output means 186a whether the voltage value is 100 mV or more. The second detection signal is determined by the second detection signal output means 186b whether the voltage value is 500 mV or more.

  Here, since the vibration of distortion is caused by the operation handle 113 being held by the player, a voltage value of 500 mV or more is not measured by the second detection signal output means 186b, but the first detection signal output means Since a voltage of 100 mV or more is measured by 186a, a first detection signal due to distortion is transmitted to the prize ball control board 203.

  In the present embodiment, the first detection signal due to “distortion” and the second detection signal due to “impact” are extracted in parallel from the external force applied to the vibration detection device 150 as described above according to the frequency band component. , Use. In particular, in this embodiment, the game ball launch control unit controls the launch unit 239 based on the first detection signal output from the first detection signal output unit 186a and the detection by the touch sensor 140 provided on the operation handle 113. Then, the abnormality handling means responds to the abnormal launch of the game ball by the operation handle 113 based on the first detection signal output from the first detection signal output means 186a and the detection by the touch sensor 140 provided on the operation handle 113. In response to the second detection signal output from the second detection signal output unit 186b, the fraud countermeasure execution unit performs the fraud response processing.

  FIG. 13 is an explanatory diagram for explaining a legitimate operation of the operation handle by the player and a fixed hit.

  The game ball launch control means detects the contact of the player's hand 117 with the operation handle 113 by the touch sensor 140 and is output from the first digital filter 184a as the first filter means in the vibration detection device 150. When the voltage signal of the first frequency band component satisfies the predetermined first condition (when the first detection signal is output to the prize ball control board 203), the launching unit 239 permits the launch of the game ball.

  When the touch sensor 140 detects contact of the player with the operation handle 113 and the first detection signal is output to the prize ball control board 203, the player actually holds the operation handle 113. This is a case where the player is operating the operation handle 113 properly (see FIG. 13A). In this way, only when the game ball firing control means detects the touch of the touch sensor 140 to the operation handle 113 by the player and the first detection signal is output to the prize ball control board 203, the launching unit 239. By allowing the game ball to be fired by the game ball, the game ball is fired only when the player legitimately grips and operates the operation handle 113, thereby preventing the abnormal operation handle 113 from being fixed. It becomes possible.

  The abnormality response executing means detects that the touch sensor 140 detects a player's contact with the operation handle 113, or the voltage signal of the first frequency band component output from the first digital filter 184a is a predetermined first condition. If only one of the conditions is satisfied, an abnormality handling process for dealing with an abnormality in the launch of the game ball by the operation handle 113 is performed.

  Although the touch sensor 140 detects that the operation handle 113 such as the contact of the player with the operation handle 113 has fallen to the ground, the voltage signal output from the first digital filter 184a is a predetermined first signal. When the condition is not satisfied, the operation handle 113 is fixed by inserting a foreign object in the gap formed in the operation handle 113, and the game ball is attempted to be fired by bringing a finger or the like into contact with the operation handle 113. (See FIG. 13B).

  With the configuration including such an abnormality handling means, when the operation handle 113 is fixed and a game ball is fired, an abnormality handling process can be performed.

  Here, in the abnormality handling process, when the winning ball control board 203 detects a firing abnormality, an abnormality notification command is transmitted to the main control board 201, and the transmitted abnormality notification command is further transmitted from the main control board 201 to the sub-control board 202. Alarm sound is output from the alarm sound sub-control board 202 and a message indicating that “the operation handle is abnormal” is displayed and voice notification is given, or the lamp control board 206 is notified by blinking of the effect light 111, etc. Or to do. As a result, the game hall staff is informed that a game operation such as fixed hitting using the operation handle 113 has been attempted, and the game hall staff visits the pachinko machine 100 equipped with the operation handle 113 to perform necessary treatment. Can be.

  Further, the fraud countermeasure executing means performs a fraud countermeasure process for responding to an illegal act on the pachinko machine 100 according to the second detection signal output from the second detection signal output means 186b. In the present embodiment, when the second detection signal indicating that an instantaneous external force (impact) is applied to an arbitrary part of the pachinko machine 100 is equal to or greater than the impact threshold (500 mV), the prize ball control board 203 is used. Is output.

  The case where the second detection signal is output is a case where the pachinko machine 100 is given a shock such as a pounding. For example, when a player improperly gives a shock to the pachinko machine 100, vibration is generated in the operation handle 113 to which the vibration detection device 150 is fixed. As a result, a voltage signal including a frequency band of 10 Hz to 50 Hz, which is a frequency characteristic of shock, is generated from the vibration sensor 170 in the vibration detection device 150, and the measurement unit passes through the filter circuit 172 and the amplification circuit 174. 180 is input.

  Here, since an impact due to the sticking occurs, a voltage of 100 mV or higher is not measured by the first detection signal output means 186a, but a voltage value of 500 mV or higher is measured by the second detection signal output means 186b. A second detection signal due to impact is transmitted to the control board 203.

  With the configuration including the fraud countermeasure execution means, the fraud countermeasure processing can be performed when an act of improperly impacting the pachinko machine 100 to obtain a large number of game balls or the like occurs.

  Here, the fraud handling processing means that when the prize ball control board 203 detects the second detection signal, a fraud notification command is transmitted to the main control board 201, and the main control board 201 sends a fraud to a management device such as a hall computer. By transmitting the fact that it has been detected or sending a fraud response command from the main control board 201 to the prize ball control board 203, the launch stop process is performed to prohibit the launch of the game ball, and the payout stop process is performed to play the game It is also prohibited to pay out balls. Further, the main control board 201 may stop the basic operation after transmitting the illegal command so that the signal from the vibration detection device 150 is not input. In this case, fraud can be further prevented by adopting a configuration in which recovery is performed by a recovery process by a game hall staff.

  In the case where a process for stopping a part or all of the game function is performed by the fraud handling process, the game state immediately before the fraud notification command based on the second detection signal is input is stored in the main control board 201. A configuration is preferable. This makes it possible to restore the gaming state to the original state when it is determined that the act is not fraudulent by the confirmation of the game hall staff and the game is restored.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the scope of the present invention. Is included in the present invention.
