Description

  The present invention relates to a gaming machine such as a pachinko machine or a slot machine, and more particularly to a gaming machine having a function of detecting and detecting whether or not the vibration is illegal.

  In gaming machines such as pachinko machines and slot machines, the issue is how to detect illegal activities that cause the player to vibrate the gaming machines and stop or prevent them from occurring. Yes. In particular, the pachinko machine that is the main game whether or not the launched game ball wins the winning opening is by shaking the pachinko machine body or hitting the glass window of the part where the game ball falls, It is thought that the trajectory of the game ball can be changed in an advantageous direction. For this reason, fraudulent acts are often performed during pachinko games, such as forcibly shaking the pachinko machine by hitting the weight on the upper plate of the pachinko machine or hitting the glass window strongly. Therefore, it is necessary to detect and notify the unauthorized vibration.

  On the other hand, when you try to stand up after stopping the game, there may be vibrations, such as when you stand up with your weight on the top plate or when you open the window frame to block the ball, but it is not illegal is there. Some recent pachinko machines are provided with push buttons near the upper plate. This is an improvement of interest by linking the image displayed on the display device of the pachinko machine and the push button, but when the vibration is generated in the pachinko machine by pressing the push button There is also. However, the vibration generated in such a case is considered to be a legitimate vibration.

  As described above, legitimate and illegal vibrations occur in pachinko machines, so if you do not detect these separately, you will notice that they are illegal against legitimate vibrations, Upon receiving a notification that it is fraudulent, the corresponding pachinko machine was confirmed, but problems such as legitimate vibrations and endless efforts occurred.

Therefore, for example, the invention described in Patent Document 1 limits the mounting position of a sensor that detects vibration. That is, it is difficult to detect the legitimate vibration by moving the mounting position of the sensor away from the legitimate vibration source, and it is easy to detect illegal vibration such as when the glass window is struck strongly. Further, a sensor that transmits an ON voltage only when vibration of a predetermined magnitude or more is generated, that is, a sensor that outputs a pulse-shaped (rectangular signal of the same level), and the voltage acquired from this sensor is An edge is detected, and the detection accuracy of unauthorized vibration is improved by using the time density and the cumulative number of the edge.
JP 2007-236486 A

  However, in the invention described in Patent Document 1, as shown in FIG. 8, a sampling time generated at a predetermined interval that is repeatedly generated is determined in advance, and how many pulses are generated during the sampling time. The time density is calculated by the above, and the number of pulses generated after the sampling time starts is counted to determine whether or not the vibration is improper.

  When a pulse related to vibration is acquired by such a method, as shown in FIG. 8B, when vibration occurs across different sampling times, the time density and the cumulative number are insufficient at any sampling time. , May not be determined to be fraudulent.

  The present invention has been made for the purpose of solving the above problems. That is, the first object of the present invention is to detect vibrations without loss and to detect illegal vibrations with high accuracy.

  Further, in the conventional gaming machine, as shown in FIG. 8C, the timing for acquiring the signal from the sensor is also determined at a predetermined interval (for example, 4 msec). Therefore, vibrations less than this interval cannot be detected accurately, while vibrations continuing beyond this interval cannot be detected accurately.

  Specifically, as shown in Table 1 below, even though a large number of pulses are generated, section (3)-(4), section (8)-(9), and section (10)-( 11) Only edges can be detected. Accordingly, even in this case, many vibrations are missed.

  This invention is made | formed in view of the said subject, and makes it the 2nd objective to acquire accurately the fine vibration with a short generation | occurrence | production interval, and to detect an improper vibration accurately.

  In order to achieve the above object, a gaming machine according to the present invention is a gaming machine having a function of detecting whether or not it is an unauthorized vibration by detecting the vibration, and is subject to vibration exceeding a predetermined value generated in the gaming machine. A vibration detection device that sequentially outputs a corresponding pulsed detection voltage in response to the occurrence of the vibration, and time measurement is started by detecting a pulse that is the detection voltage, and time measurement end information when a predetermined time elapses And when a predetermined N number of pulses (N is a natural number of 2 or more) including the relevant pulse are detected before the time measurement end information is output from the pulses detected by the time measuring means, Determination means for outputting notification information indicating that, and, in the case of N ≧ 3, N-1 detection means composed of the time measurement means and the determination means are provided, and a plurality of the detection means Generating a pulse Characterized in that it functions in one by one turn.

  As a result, the sampling time sequentially occurs in response to the received pulse signal, so that even if a group of continuously generated pulse signals crosses one sampling time, it falls within another sampling time. Therefore, it is possible to detect the vibration with high accuracy without missing the vibration considered to be.

  The invention of the present application makes it possible to detect whether or not the vibration is illegal based on a large amount of information because it is possible to determine whether or not the vibration is illegal based on a large amount of information. .

  Hereinafter, an embodiment of a gaming machine according to the present invention will be described with reference to the drawings, taking a pachinko machine as an example.

The outer frame 111 is a thin square cylindrical frame body whose front and rear surfaces are open, and many members of the pachinko machine 100 are disposed inside the outer frame 111.

  The front frame 112 is a thin square cylindrical frame that is attached to the outer frame 111 so as to be openable and closable, and most members of the pachinko machine 100 are attached to the front frame. Therefore, even when the pachinko machine 100 is attached to the island, that is, when the outer frame 111 is fixed to the island, the front frame 112 is opened with respect to the outer frame 111 so that the back side of the pachinko machine 100 is removed. It is also possible to work.

  The front frame 112 is firmly fixed to the outer frame 111 via a hinge. Further, a lower plate 114 and an upper plate 115 that are open at the top are fixed to the front lower portion of the front frame 112. Therefore, it is possible to improperly shake or tilt the pachinko machine 100 by grasping the lower plate 114, the upper plate 115, etc. and applying force.

  Further, a handle base 116 is fixed to the right side of the lower plate 114 on the front frame 112, and a firing handle 119 is rotatably attached to the handle base 116. A firing motor (not shown) is fixed behind the firing handle 119, and a hitting ball is connected to the rotation shaft of the firing motor. When the firing handle 119 is rotated, a driving power is supplied to the firing motor, and the game ball supplied from the upper plate 115 is blown out to the game board based on the driving of the hitting ball. In this case, a vibration is generated in the pachinko machine 100, but the vibration is a normal vibration.

  The window frame 113 is a frame that fixes a glass window 126 disposed on the front surface of the game board so that the behavior of the game ball falling on the game board can be seen. The window frame 113 is a frame disposed at the foremost side of the pachinko machine 100, and various decorations are provided, and a speaker 118 that outputs game sounds is provided on the back. The window frame 113 is attached to the front frame 112 so as to be openable and closable, for example, when a game ball is jammed on the game board, and vibration is generated when the window frame 113 is opened and closed.

  In addition, two push buttons 128 are provided upward on the left side of the lower plate 114. The push button 128 is an apparatus for causing a player to participate in the production, for example, when there is an effect that prompts the user to press the push button in a reach action or the like, and a different effect is made by pressing any one of the push buttons. is there. For example, in the case where the effect is such that the push button must be pressed many times in a short period of time (sequential hitting), a legitimate vibration is generated by hitting the button repeatedly.

  FIG. 2 is a front view of the game board.

  The game board 130 is a central part of the game for the player, such as whether or not the game ball 199 that has been launched falls in a complicated manner and the game ball 199 wins. The game board 130 includes a special winning opening 132, a starting gate 133, a large winning opening 134, a general winning opening 135, an accessory 136, an accessory opening 137, a game ball passage 138, and a board 131. The distribution means 201 and a nail (not shown) are attached, and are arranged so that the game board 130 can be seen through the glass window 126 of the window frame 113.

  The plate body 131 is a plate for fixing each component member constituting the game board 130. In addition to the above, nails (not shown) for complicating the falling direction of the game ball are also planted on the plate body 131.

  The general winning opening 135 is formed in a pocket shape whose upper surface is always open, and includes a switch (not shown) that detects that a game ball has won the general winning opening 135.

  The start gate 133 is formed in a gate shape whose upper and lower surfaces are always open, and includes a switch (not shown) that detects that a game ball has passed through the start gate 133. Even if a game ball passes through the start gate 133, no prize ball is paid out.

  The accessory port 137 is a horizontally elongated rectangular hole provided in the plate body 131 for guiding the game ball 199 to the game ball passage 138. The accessory port 137 is a horizontally long rectangular lid that normally closes the accessory port 137 and opens the accessory port 137 for a predetermined time based on a predetermined voltage (for example, passage of a game ball to the start gate 133). 141 is provided. A game in which the upper edge of the lid 141 tilts toward the front of the game board 130 so that the upper part of the accessory port 137 can be widely opened with the lower edge as an axis, and falls on the back side of the lid 141. It is possible to catch the ball 199.

  The game ball passage 138 is a passage for guiding the game ball 199 entering the accessory port 137 to the sorting device. In the figure, the path of the game ball 199 in the game ball passage 138 is indicated by an arrow.

  The accessory 136 is a device that complicates and randomizes the falling path of the game ball 199 by rotating an obstacle that prevents the game ball 199 from falling. In the accessory 136 shown in the figure, a disk having a plurality of protrusions that are obstacles is arranged in an inclined manner and rotated around the center of the disk, so that the accessory port 137 and the game ball passage 138 are rotated. After that, the falling of the game balls 199 distributed to the role side by the distribution means 201 is inhibited.

  The specific winning opening 132 is a pocket-shaped member called a V zone whose upper surface is always open. When the game ball 199 wins the specific winning opening 132, it becomes a big hit. Therefore, it is of great concern for the player whether or not to win the specific prize opening 132, and when the game ball 199 is positioned in the vicinity of the specific prize opening 132, the player may hit the glass window 126. Many.

  The distribution means 201 is a member that distributes the game balls 199 to the left and right by receiving the game balls 199 falling through the game ball passages 138 and swinging the inclination of the distribution means 201 itself and changing the tilt state. The allocating means 201 is a member that determines whether or not the game ball 199 is directed toward the specific prize opening 132 side. When the game sphere 199 gets on the distribution means 201, the glass window 126 may be hit. Many.

  The big prize opening 134 is a horizontally long rectangular hole provided in the plate body 131 and includes a switch (not shown) that detects that the game ball 199 has won, and the number of game balls 199 that won the big prize opening 134. A voltage for executing the payout of the prize ball according to the is generated. Similarly to the role opening 137, the special winning opening 134 is normally closed, and the special winning opening 134 is set at regular intervals based on a predetermined voltage (the winning of a game ball to the specific winning opening 132). Is provided with a door 142 that opens a predetermined number of times.

  FIG. 3 is a block diagram showing a device configuration and a functional configuration related to vibration detection of the pachinko machine.

  As shown in the figure, the pachinko machine 100 includes a vibration detection device 301, a determination unit 361, a time measurement unit 362, an initialization unit 363, a notification unit 313, and a CPU (central processing unit) having an input port 341. 304 and a storage device 306. The CPU 304 and the storage device 306 are provided on the main control board 123. In addition, the storage device 306 holds a determination unit 361, a timer unit 362, an initialization unit 363, and a notification unit 313. In the present embodiment, the determination unit 361, the timing unit 362, the initialization unit 363, and the notification unit 313 are programs that are appropriately executed by the CPU 304 so that their functions are used as means. It is realized.

  The vibration detection device 301 is a sensor that outputs a pulsed detection voltage in response to a vibration greater than a predetermined value generated in the pachinko machine 100. Specifically, a sensor that outputs a pulse signal when the displacement of the weight due to vibration, the speed of the weight, or the acceleration of the weight exceeds a predetermined displacement, speed, or acceleration can be exemplified. As a sensor that outputs a pulsed detection voltage, for example, when a weight is displaced more than a predetermined displacement, a mechanical threshold is set so that the switch is maintained in an ON state while the displacement continues. May be determined. The vibration sensing part of the vibration detection device 301 converts vibration directly into a voltage or the like and outputs a so-called raw waveform. The raw waveform may be converted into a pulsed detection voltage by a comparator or the like.

  Here, the detection voltage is a voltage output from the vibration detection device 301. As shown in FIG. 4, the detection voltage output from the vibration detection device 301 is a digital signal, a pulse signal that suddenly rises from the low state to the hi state, maintains the hi state, and suddenly falls to the low state. It is. The figure shows a simplified signal for explanation. Note that “edge” means a signal state of a rising portion or a signal state of a falling portion.

  The input port 341 is an interface provided in the CPU 304, and is an input terminal for the CPU 304 to acquire an external signal. In the case of the present embodiment, since the change in the detection voltage from the vibration detection device 301 is more gradual than the timing at which the CPU 304 acquires a signal, a normal input port (the CPU 304 acquires the voltage state at a predetermined interval timing ( Not interrupt).

  This description does not deny the use of interrupt terminals.

  The storage device 306 is a device that stores a program and can provide the stored program to the CPU 304 as appropriate. Specifically, it is a ROM, a RAM, a hard disk, or the like.

  The CPU 304 is an element that acquires a program from the storage device 306 and performs various calculations based on the acquired program, and is a central processing unit. Therefore, for example, while the CPU 304 acquires and processes the determination unit 361 that is a program, the CPU 304 functions as a determination unit. Further, the CPU 304 can perform parallel processing (including pseudo) and can function as N−1 determination means.

  Note that the CPU 304 functions as a timing unit by reading the timing unit 362 and can also function as a plurality of timing units. The same applies to the initialization unit 363 and the notification unit 313.

  The determination unit 361 is a processing unit that can count pulses, and is a processing unit that counts pulses from the initial state until acquisition of later-described timing end information from the timing unit 362. In addition, when the determination unit 361 counts N pulses until the timing end information is acquired, the determination unit 361 outputs notification information indicating that.

  Here, N is a natural number of 2 or more, and is a numerical value set in advance. For example, if N is set to 3, the notification information is output if the determination unit 361 counts three pulses before obtaining the timing end information.

  Further, the determination unit 361 includes a self-initialization unit (not shown) that counts N pulses before acquiring the timing end information or initializes itself when the timing end information is acquired.

  Note that the determination unit 361 also initializes when initialization information (described later) output from the initialization unit 363 is acquired.

  Further, N-1 determination units 361 can function at the same time. That is, when N is set to 3, two determination units 361 function at the same time. As shown in FIG. 4, when the first determination unit 361 starts counting pulses from the pulse <1>, the second determination unit 361 starts counting from the pulse <2>. . That is, the second determination unit sequentially detects the detection voltage pulses sequentially output after the first determination unit. When there are three or more determination units 361, pulse counting is started in forward order. Each determination unit 361 holds a counted value. In addition, each determination unit 361 independently outputs notification information and has a self-initialization unit.

  The timing unit 362 is a processing unit that starts timing after detecting the pulse of the detection voltage and outputs timing completion information when a predetermined time has elapsed, and functions as many as the number of the determination units 361. It has become something that can be. The determination unit 361 that starts counting pulses based on the same pulse and the time measuring unit 362 that starts measuring time are linked to form a detection unit 370. In the detection unit 370, the corresponding determination unit 361 can recognize the timing end information output from the time measuring unit 362. In addition, the time measuring unit 362 initializes itself in the same manner when the attached determination unit 361 initializes itself.

  Note that the timer unit 362 also initializes when initialization information (described later) output from the initialization unit 363 is acquired.

  Further, the detection unit 370 configured by the time measuring unit 362 and the determination unit 361 may not be able to detect all the pulses with respect to the pulsed detection voltage sequentially output from the vibration detection device 301. It is only necessary to sequentially detect the pulses that can be detected, and such processing is also included in the present invention. That is, in the present invention, the term “one by one” means one by one for those that can be detected.

  When the initialization unit 363 acquires the notification information output by counting N pulses before any of the N-1 determination units 361 acquires the timing end information, It is a processing unit that outputs initialization information to the determination unit 361 and all the time measuring units 362.

  The notification unit 313 is a processing unit that transmits warning information to various devices when the notification information output from any one of the N-1 determination units 361 is acquired, and is realized by a program. It is what is done.

  In addition, although the determination part 361, the time measuring part 362, the initialization part 363, etc. were demonstrated as a program which functions by CPU304, this invention is not necessarily limited to this. For example, the determination unit 361 may be realized as a determination unit that is an independent device. Further, the time measuring unit 362 may be a time measuring means as a device that functions outside the CPU 304.

  Next, the flow of unauthorized vibration detection in the pachinko machine 100 will be described. In the following description, it is assumed that unauthorized vibration has occurred when a pulse is detected three times at a predetermined time.

  First, the CPU 304 obtains a detection voltage pulse <1> (see FIG. 4) from the vibration detection device 301. When the pulse <1> is acquired, the first determination unit 361 starts counting pulses by setting the pulse <1> to 1 (starting pulse). In addition, the first time measuring unit 362 starts measuring time.

  Next, when the next pulse <2> is acquired within a predetermined time, the first determination unit 361 increases the count by one. On the other hand, the second determination unit 361 starts counting pulses by setting pulse <2> to 1 (starting pulse). In addition, the second timing unit 362 starts timing.

  Next, when the first time measuring unit 362 measures a predetermined time and outputs time measurement end information, the first determination unit 361 associated with the first time measuring unit 362 initializes itself.

  Thereafter, when the pulse <3> is acquired, the second determination unit 361 increases the count by one. On the other hand, the initialized first determination unit 361 sets the pulse <3> to 1 (starting pulse) and starts counting pulses again. In addition, the first time measuring unit 362 starts measuring time.

  Thereafter, when the pulse <4> is acquired, the second timing unit 362 does not output the timing end information, so the second determination unit 361 increments the count by one.

  Here, since the second determination unit 361 detects three pulses within a predetermined period of time (that is, before acquiring the timing end information), the second determination unit 361 outputs notification information.

  The initialization unit 363 that has acquired the notification information outputs the initialization information to the first determination unit 361 and the first time measurement unit 362. On the other hand, the second determination unit 361 initializes itself. Therefore, after the second determination unit 361 detects three pulses, the first determination unit 361, the second determination unit 361, the first timing unit 362, and the second timing unit 362 are all in the initial state. Become. (The broken line in FIG. 4 indicates the time that would have been timed if not initialized.)

  Next, when the pulse <5> is acquired, the first determination unit 361 starts counting with the pulse <5> set to 1 (starting pulse), and the first time measuring unit 362 starts counting. Subsequently, when the pulse <6> is acquired, the second determination unit 361 starts counting by setting the pulse <6> to 1 (starting pulse), and the second timing unit 362 starts counting. The first determination unit 361 increases the count by one.

  Subsequently, since the first timing unit 362 has not yet output the timing end information when the pulse <7> is acquired, the first determination unit 361 sets the count to 3, that is, three pulses. When it is detected, the notification information is output. Accordingly, the second determination unit 361 and the second timing unit 362 are initialized by the initialization unit 363, and the first determination unit 361 and the first timing unit 362 are initialized based on the self-initialization unit.

  As described above, if three pulses are generated within a predetermined time, it is possible to detect the three pulses and output the notification information regardless of the generation pattern. Therefore, the notification unit 313 that acquires the notification information can reliably transmit the warning information to various devices, and can perform various processes even if unauthorized vibration occurs.

  In the above description, N is assumed to be 3. However, by setting N and the time until the timing end information is output in various combinations, it is possible to distinguish illegal vibrations from legitimate vibrations from various vibrations. It becomes possible to process.

(Embodiment 2)
Next, another embodiment relating to acquisition of the detection voltage will be described. Note that this embodiment also detects vibration of the pachinko machine 100.

  FIG. 5 is a block diagram showing a device configuration and a functional configuration related to vibration detection of the pachinko machine.

  As shown in the figure, the pachinko machine 100 includes a CPU (central processing unit) having a vibration detection device 301, a determination unit 361, a timing unit 362, an initialization unit 363, a detection unit 364, and an interrupt terminal 342. ) 304 and a storage device 306. The CPU 304 and the storage device 306 are provided on the main control board 123. In addition, the storage device 306 holds a determination unit 361, a time measurement unit 362, a detection unit 364, and a notification unit 313 as programs. In the present embodiment, the determination unit 361, the timing unit 362, the initialization unit 363, the detection unit 364, and the notification unit 313 are programs that are executed by the CPU 304 as appropriate. The function is realized.

  Since the vibration detection device 301 is the same as described above, the description thereof is omitted.

  The interrupt terminal 342 is an interface provided in the CPU 304, and is an input terminal described as an INT terminal or an IRQ terminal. When a digital signal is input to the interrupt terminal 342, the process being executed by the CPU 304 is temporarily interrupted and another predetermined process is executed. For example, if the CPU 304 determines that a digital signal has been input when the voltage applied to the interrupt terminal 342 changes from a low state to a hi state, that is, when it rises, the CPU 304 acquires the rising edge of the pulse and the interrupt is generated. Will be executed. Therefore, vibration can be detected at any time regardless of the processing cycle normally performed by the CPU 304.

  Depending on the type of the CPU 304, an interrupt may occur when the voltage applied to the interrupt terminal 342 changes from the hi state to the low state. Further, according to the type of the vibration detection device 301, there are various types such as those that are in a hi state when vibration is detected and those that are in a low state. Therefore, in order to match the CPU 304 and the vibration detection device 301, the interrupt terminal 342 and the vibration detection device 301 may be connected via an inverter.

  The storage device 306 and the CPU 304 are the same as described above.

  The detection unit 364 is a processing unit that outputs detection information as an occurrence of vibration when an interruption occurs in the CPU 304 due to a change in the voltage applied to the interrupt terminal 342.

  The timing unit 362 is a processing unit that measures the time from when the detection information output by the detection unit 364 is acquired until the next detection information is acquired, and outputs the timing information as a timing result each time.

  The determination unit 361 is a processing unit that outputs notification information indicating that when the timing information is equal to or less than a predetermined value. Note that the determination unit 361 may output notification information indicating that when the timing information is in a range between the first predetermined value and the second predetermined value.

  Note that the determination unit 361 may output the notification information when timekeeping information equal to or less than the predetermined value is continuously acquired a predetermined number of times.

  The notification unit 313 is the same as described above.

  According to the above configuration, even if vibration with a very high frequency occurs in the pachinko machine 100, the CPU 304 detects the pulse from the vibration detection device 301 regardless of the timing when the CPU 304 obtains information from the port. It is possible to determine whether or not the vibration is illegal based on the occurrence state. Therefore, it is possible to detect unauthorized vibration with high accuracy.

(Embodiment 3)
Next, another embodiment relating to acquisition of the detection voltage will be described. Note that this embodiment also detects vibration of the pachinko machine 100.

  FIG. 6 is a block diagram illustrating a device configuration and a functional configuration related to vibration detection of the pachinko machine.

  As shown in the figure, the pachinko machine 100 includes a vibration detection device 301, a determination unit 361, a timing unit 362, a detection unit 364, a first accumulation unit 365, a second accumulation unit 366, and a notification unit 313. A central processing unit (CPU) 304 having an interrupt terminal 342 and a storage device 306. The CPU 304 and the storage device 306 are provided on the main control board 123. In addition, the storage device 306 holds a determination unit 361, a timing unit 362, a detection unit 364, a first accumulation unit 365, a second accumulation unit 366, and a notification unit 313. In the present embodiment, the determination unit 361, the timing unit 362, the detection unit 364, the first accumulation unit 365, the second accumulation unit 366, and the notification unit 313 are programs, and the CPU 304 appropriately. These functions are realized by being executed in step (b).

  Since the vibration detection device 301 is the same as described above, the description thereof is omitted.

  The interrupt terminal 342 is an interface provided in the CPU 304, and is an input terminal described as an INT terminal or an IRQ terminal. In the case of this embodiment, the interrupt terminal 342 to which the detection voltage (digital signal) from the vibration detection device 301 is input generates an interrupt when the rising signal is input, and the falling signal is This pin also generates an interrupt when it is input. Further, the CPU 304 can distinguish and recognize whether an interrupt is generated by a rising signal or an interrupt is generated by a falling signal. Specifically, the interrupt terminal 342 can exemplify a terminal called an input capture terminal.

  The storage device 306 and the CPU 304 are the same as described above.

  When a rise occurs in the voltage applied to the interrupt terminal 342 and an interrupt occurs, the detection unit 364 outputs edge information including information indicating that the interrupt is caused by the rise, and the interrupt terminal When a fall occurs in the voltage applied to 342 and an interrupt occurs, the processing unit outputs edge information including information indicating that the interrupt is caused by the fall. The processing unit outputs detection information, which is information indicating that an interrupt has occurred, along with the edge information.

  The time measuring unit 362 is a processing unit that calculates the time from when the detection information output by the detection unit 364 is output until the next detection information is acquired from the value of the counter (program timer counter). It is a processing unit that outputs information each time.

  The first accumulating unit 365 is based on the time information sequentially output from the time measuring unit 362 and the edge information output from the detecting unit 364, and the time from when the detection signal rises to when it falls (hereinafter referred to as “H pulse width”). It is a processing unit that extracts only the time information indicating () and accumulates the H pulse width.

  Note that the minimum value adopted as the H pulse width may be set as a threshold, the threshold and the H pulse width may be compared one by one, and only the H pulse width equal to or greater than the threshold may be accumulated. As a result, it is possible to remove minute vibrations and improve the accuracy of detecting illegal vibrations. Furthermore, the maximum value may be set as the threshold value. Also, the range to be adopted may be set.

  The second accumulating unit 366 is based on the time information sequentially output from the time measuring unit 362 and the edge information output from the detecting unit 364, and is the time from the detection signal falling to the rising time (hereinafter referred to as “L pulse width”). It is a processing unit that extracts only the timing information indicating "." And accumulates the L pulse width.

  The maximum value that can be adopted as the L pulse width is set as a threshold, and when the L pulse width exceeding the threshold is acquired, the initial value for initializing the accumulation of the H pulse width and the accumulation of the L pulse width It is desirable to output conversion information. Furthermore, the minimum value may be set as a threshold value, and accumulated time information and non-accumulated time information may be selected based on the threshold value. As a result, it is possible to improve the accuracy of detecting unauthorized vibration.

  The determination unit 361 is a processing unit that outputs notification information when the ratio of the accumulated H pulse width value to the accumulated L pulse width value is equal to or greater than a predetermined value, that is, when pulses frequently occur. . The determination unit 361 determines that the ratio of the accumulated H pulse width value to the accumulated L pulse width value is equal to or larger than the first predetermined value and the ratio is equal to or smaller than the second predetermined value. Notification information indicating that may be output.

  The notification unit 313 is the same as described above.

  According to the above configuration, vibration generated in the pachinko machine 100 can be analyzed in more detail, and it can be determined whether or not the vibration is illegal. Therefore, vibration determination accuracy is improved, and it is possible to suppress erroneous determination, misrecognition, informing the player of an unpleasant feeling, oversight of incorrect vibration, and loss to the hall. It becomes.

  In the above embodiment, the H pulse width and the L pulse width are obtained by recognizing and distinguishing the rising edge and the falling edge of the detection voltage. However, the present invention is not limited to this.

  For example, rising and falling always occur alternately, and in a steady state where no special vibration has occurred (such as a state immediately before the pachinko hall is opened), a sufficiently long pulse width must be an L pulse width. The H pulse width and the L pulse width may be accumulated based on such assumptions as above. In this case, it is not necessary to distinguish between the rising edge and the falling edge of the detection voltage.

FIG. 7 is a block diagram showing a device configuration and a functional configuration related to vibration detection of the pachinko machine.

  As shown in the figure, the pachinko machine 100 includes a vibration detection device 301, a frequency conversion device 307, a voltage conversion device 308, a CPU (central processing unit) 304 having a parallel port 305, and a storage device 306. ing. Further, the frequency conversion device 307, the voltage conversion device 308, the CPU 304, and the storage device 306 are provided on the main control board 123. In addition, the storage device 306 holds a determination unit 361 and a notification unit 313. In the present embodiment, the determination unit 361 and the notification unit 313 are programs, and their functions are realized by being executed by the CPU 304 as appropriate.

  The vibration detection device 301 associates the intensity (intensity) of vibration generated in the pachinko machine 100 with a voltage, and can output a change in the intensity of the vibration as a detection voltage over time, a so-called raw waveform of vibration. It is a sensor that can output. Specifically, a sensor that detects displacement, velocity, and acceleration due to vibration as vibration intensity can be exemplified. Further, a sensor that detects vibration as a change in capacitance, a sensor that detects using eddy current, a sensor that detects using the behavior of a sphere rolling inside a curved surface, and the like can be exemplified.

  Note that the vibration detection device 301 may output a pulse signal as described in the above embodiment as a detection voltage.

  The frequency conversion device 307 is a device that changes the frequency of the detection voltage output from the vibration detection device 301 to a voltage. For example, the frequency conversion device 307 is a device called an F / V converter that outputs a voltage proportional to (or inversely proportional to) an input frequency.

  The voltage converter 308 is a device that outputs digital numerical information corresponding to an input voltage, and can be exemplified by a device called an A / D converter.

  The parallel port 305 is an interface provided in the CPU 304 and is an input / output unit that receives digital numerical information transmitted from the voltage converter 308.

  The storage device 306 is a device that stores a program and can provide the stored program to the CPU 304 as appropriate. Specifically, it is a ROM, a RAM, a hard disk, or the like.

  The CPU 304 is an element that acquires a program from the storage device 306 and performs various calculations based on the acquired program, and is a so-called central processing unit. Therefore, while the CPU 304 acquires and processes the determination unit 361 that is a program, the CPU 304 functions as a determination unit. The notification unit 313 is the same.

  The determination unit 361 is a processing unit that outputs notification information that is a result of comparing numerical information acquired via the parallel port 305 with a predetermined threshold value. For example, the notification information is output when the numerical information exceeds a threshold value. In this case, if larger numerical information is input as the frequency of the detection voltage is higher, the notification information is output when vibration having a frequency higher than a predetermined frequency occurs. These relationships vary depending on the performance and specifications of the frequency converter 307 and the voltage converter 308.

  The notification unit 313 is a processing unit that transmits warning information to various devices when the notification information from the determination unit 361 is acquired, and is realized by a program.

  In addition, although the determination part 361 and the alerting | reporting part 313 were demonstrated as a program which functions by CPU304, this invention is not necessarily limited to this. For example, the determination unit 361 may be realized as a determination unit that is an independent device. Further, the notification unit 313 may be realized as a notification unit.

  As described above, in order to determine the state of vibration using data corresponding to the frequency of the detection voltage output from the vibration detection device 301, the vibration generated without imposing a burden on the CPU 304 is detected and used as a determination material. be able to. Therefore, unauthorized vibration can be detected with high accuracy without imposing a burden on the CPU 304.

  In Embodiments 1 to 4 described above, the CPU and the like are described as being included in the main control board, but the present invention is not limited to the type of board. For example, the present invention may be applied to any board provided in the pachinko machine 100 such as a sub control board and a production control board. Further, as long as the pachinko machine 100 includes a CPU on one substrate and a storage device on another substrate, the CPU may extend over a plurality of substrates.

Means for outputting the detection information, timing means for measuring the time from when the detection information is acquired until the next detection information is acquired, and when the measured time is less than or equal to a predetermined time, this is indicated It may be provided with determination means for outputting notification information.

  According to this, since the edge of the pulse signal is detected by interruption, it is not necessary to set the timing for acquiring the signal from the sensor, and the edge of the pulse signal can be detected in more detail. Therefore, even if minute vibrations are generated, the vibrations can be separated and detected with high accuracy, and it can be accurately determined whether the vibrations are illegal.

  In addition, the gaming machine is a gaming machine having a control board that performs control related to gaming, and includes a vibration detection device that outputs a pulsed detection voltage corresponding to a vibration greater than a predetermined value generated in the gaming machine, the control The board outputs detection information when an interrupt occurs due to a rising edge of the detection voltage input to the CPU (Central Processing Unit) having the interrupt terminal to which the detection voltage is input and the interrupt terminal. Detection means that outputs detection information even when an interrupt occurs due to a fall, and measures the time from when the detection information is acquired until the next detection information is acquired, and sequentially outputs time information about the measured time Time counting means, first accumulating means for acquiring and accumulating the sequentially output timing information one by one, and timing information different from the timing information acquired by the first accumulating means, and accumulating And a determination unit that outputs notification information indicating that when the ratio between the first cumulative time and the second cumulative time within a predetermined time is equal to or greater than a predetermined value.

  According to this, it is determined whether or not the generated vibration is illegal based on the pulse width and the interval at which the pulse is generated. That is, since it is possible to determine whether or not it is illegal with many elements, it is possible to determine the type of vibration more accurately.

  Further, the gaming machine is a gaming machine having a control board that performs control related to gaming, and a vibration detection device that detects a vibration state of the gaming machine and outputs a voltage corresponding to the strength of the vibration as a detection voltage.

Therefore, high-frequency vibrations and, conversely, low-frequency vibrations can be used for the determination without imposing a burden on the CPU. It becomes possible.
