Description

  The present invention relates to a gaming machine such as a slot machine, a fraud detection method in a gaming machine, and a program.

  A gaming machine such as a slot machine allows a player to enjoy a game by inserting a predetermined number of medals into the gaming machine. The medals necessary for the game can be borrowed with a medal lending machine provided in the game hall, and the game can be started by inserting it into the medal slot of a desired gaming machine. The gaming machine includes a medal selector for counting the number of inserted medals, and a hopper device for paying out medals in accordance with winnings.

A general hopper device has a hopper tank, a plurality of medal holes into which medals dropped from the hopper tank fit, a rotating disk that guides the medals to the medal outlet, and a game by rotating the rotating disk. Hopper motor for paying out medals to a person, a counter roller for counting the number of medals paid out, and a sensor attached thereto (for example, a photo interrupter: a light emitting element and a light receiving element in a case having a detection groove) Are arranged so as to face each other and detect a passing object between detection grooves in a non-contact manner). The medal fitted in the hole provided in the rotating disk moves along with the rotation and is guided toward the medal passage at the medal payout port. At this time, the counter roller that comes into contact with the medal guided to the passage rotates, and the protrusion provided on the counter roller enters the detection groove of the sensor, blocks the light of the light source, and the light receiving element detects this. When one medal is paid out, the medal comes into contact with the counter roller and pushes it once, so that the number of paid-out medals can be counted based on the number of detections of the sensor provided on the medal.

FIG. 3 is a functional block diagram of the slot machine according to the embodiment of the invention.
In FIG. 3, reference numerals 200 and 201 denote a main board and a sub board, each incorporating a CPU, ROM, and RAM. The main board (control unit) 200 performs management of the number of inserted medals, payout, reel rotation and stop control, winning process, and the like. The sub-board 201 performs processing such as effect display based on the winning process. An operation unit 202 includes switches such as a start switch 134, a stop switch 140, and a bet switch. A reel unit 203 includes three rotating reels. An effect display unit 204 includes a game display unit 131, internal illumination of a reel, a liquid crystal display device, a speaker, and the like. The effect display unit 204 notifies the winning combination and the pressing order obtained by the winning process. A power supply unit 205 supplies power to each unit.

  Reference numeral 2 denotes a hopper device for paying out medals. The structure of the hopper device will be described in detail later. The hopper device 2 includes a medal payout sensor 43 for counting the number of payout medals, and a hopper motor 34 for rotating a rotating disk to pay out medals. The hopper motor 34 is controlled by a medal payout command (control signal) from the main board 200 (that is, outside the hopper device 2).

  The main board 200 performs a lottery at a predetermined timing, and a lottery means 200a for sending the lottery result to the medal payout signal generator 200b, and a drive signal for the hopper motor 34 for rotating the rotating disk to pay out the medal. A medal payout control signal which generates a medal payout control signal and temporarily turns off the medal payout control signal so as to temporarily stop the rotating disk based on the lottery result from the lottery means 200b; A medal payout sensor monitoring unit 200c that monitors the sensor 43 and determines that the medal payout sensor 43 detects a payout of a medal when the rotating disk is stopped. The reason why the rotating disk is temporarily stopped based on the lottery result in the embodiment of the present invention is to make the payout of medals irregular. The lottery means 200a, the medal payout signal generating unit 200b, and the medal payout sensor monitoring unit 200c are realized by hardware such as an IC or software by a program stored in the CPU and ROM. Since the main board 200 has lottery means (known) for games, the lottery means 200b may also be used.

  4 is a front view (FIG. 4A), a right side view (FIG. 4B), and a top view (FIG. 4C) of the hopper device. FIG. 5 is an exploded perspective view of the hopper device on the hopper tank side, and FIG. 6 is an exploded perspective view of the hopper device side of the hopper device. FIG. 7 is a detailed top view of the rotary disk 3 for explaining the medal payout operation. In FIG. 7, M indicates a medal discharging route.

  The illustrated hopper apparatus is roughly divided into a hopper tank 1 for storing medals M and a main body (hopper apparatus 2) for discharging medals M stored in the hopper tank 1 one by one.

  The hopper device 2 can be broadly divided into a hopper chassis 2a and a plurality of, in this case, five medal pits, that are rotatably supported by the hopper chassis 2a and in which the medals M dropped from the hopper tank 1 fit one by one from above. A rotating disk 3 having 3a and a hopper motor 34 for rotating the rotating disk 3 are provided. When the rotary disk 3 is rotated by the driving force of the hopper motor 34, the medal M dropped into the medal drop hole 3a is discharged from the medal discharge port X to the outside.

  A base plate 5 is obliquely attached to the upper part of the hopper chassis 2a. A hopper motor 34 is fixed to the base plate 5. The output shaft 34a of the hopper motor 34 passes through the base plate 5 and protrudes substantially at the center of the upper surface thereof. Since the base plate 5 is inclined, the output shaft of the hopper motor intersects the vertical direction. For this reason, the rotating disk 3 is high on the medal discharge port side and low on the opposite side.

  A housing support 4 is located on the base plate 5. A protruding protrusion is formed around the housing support 4. The part of the medal discharge port X of the projecting edge is notched, and the medal is discharged through this part.

  When the medal M that has fallen into the medal drop hole 3a of the rotating disk 3 is positioned at the medal discharge port X along with the rotation of the rotating disk 3, the medal M is prevented from moving by the guide pin 36, and the medal discharge port X from the medal drop hole 3a. It is pushed out and discharged to the outside. In this way, the medals M are discharged in order as the rotating disk 3 rotates.

  Both the hopper tank 1 and the hopper chassis 2a are made of resin.

  In the hopper device according to the embodiment of the present invention, the counter roller 7 (provided on the counter arm 8) for counting the paid-out medals rotates around the separator 6. The medal inserted into the hole provided in the rotating disk 3 moves as the rotating disk 3 rotates, and is pushed out by the guide pin 36 at the medal discharge port X and guided toward the medal path. At this time, the medal contacts the roller 7 provided on the counter arm 8 and rotates it in the direction of arrow A in FIG. As a result, the protrusion provided on the counter arm 8 causes the game medal payout sensor 43 (for example, a photo interrupter: a light emitting element and a light receiving element to be opposed to each other in a case having a detection groove, and a passing object between the detection grooves is not contacted. Between the detection grooves), the light from the light source is blocked, and the light receiving element detects this. In this way, when one medal is paid out, the medal touches the roller 7 and presses it once, so that the number of paid-out medals can be counted based on the number of detections of the sensor 43.

  The two guide pins 36 are provided in the vicinity of the medal discharge port X of the housing support 4. The two guide pins 36 are attached to the guide pin presser 10 via guide pin springs 37, respectively. The guide pin 36 is pressed upward by a guide pin spring 37 and protrudes from the surface of the housing support 4 by about 1 mm. Due to the elasticity of the guide pin spring 37, when the guide pin 36 is pushed from above, the guide pin 36 retracts into the housing support 4, and the head of the guide pin 36 coincides with the surface of the housing support 4.

  The medal payout operation will be described with reference to FIG. When the medal M that has fallen into the medal drop hole 3a of the rotating disk 3 is positioned at the medal discharge port X as the rotating disk 3 rotates, the medal M hits the guide pin 36, and the medal M is pushed outward as the rotating disk 3 rotates. It is. The counter roller 7 provided on the counter arm 8 is expanded in the direction of the arrow A by the medals M pushed out at that time, and passes between the game medal guide 12, the separator 6 and the counter roller 7, and the medal M is a medal. It is discharged outside through the passage portions 23 and 24. When the medal M is discharged and the contact is released, the counter roller 7 returns to the original position by the elasticity of the counter pulling spring 9 (see FIG. 6). The game medal guide 12 regulates the movement of the medals and moves the medals smoothly along the medal path. When guiding medals to the medal passage portions 23 and 24, the two guide pins 36 play different roles. When the rotary disk 3 rotates in the clockwise direction, the guide pin 36a first contacts the medal and pushes the medal outward. The guide pin 36b further moves the medals moving toward the outer edge in the direction of the medal passage portions 23 and 24 while restricting the medals from moving in the rotation direction of the rotary disk 3.

  Next, the principle of the apparatus / method according to the embodiment of the present invention will be described with reference to the flowchart of FIG. 8 and the timing chart of FIG. FIG. 8 is a flowchart showing a payout process according to the embodiment of the invention. FIG. 9A shows an example of a medal payout control signal (hopper drive signal) and a payout sensor output signal according to the embodiment of the invention, and FIG. 9B shows a conventional medal payout control signal (hopper drive signal). An example of a payout sensor output signal is shown. FIGS. 9A and 9B show examples in which five medals are paid out.

  The payout sensor 43 was able to obtain a medal illegally as described above, i.e., by inserting a wire, a metal plate or the like from the medal passage portions 23, 24 to obstruct the movement of the counter roller. This is because a simple counting process was performed based on the output. Therefore, if the output waveform of the payout sensor 43 is examined to distinguish between an actual payout signal and an illegal act, the aforementioned illegal act becomes difficult. The output waveform of the payout sensor 43 is a pulse train having a substantially constant width and a constant interval as shown in FIG. 9B. However, when the movement of the counter roller is inhibited, such a pulse train is not obtained. In the case of a non-regular pulse train, for example, a DC signal that keeps on (payout sensor = detection) for a long time is clearly abnormal. No longer give.

  However, it can be considered that it is actually difficult to determine whether or not the fraudulent act is by examining the output waveform of the payout sensor 43. In order to accurately measure the pulse waveform, a device for that purpose is required, and if it is realized on the main board 200, a considerable amount of CPU power is used. In reality, it is difficult to impose such processing newly because the CPU capacity of the main board 200 has no margin. Further, since the mechanical operation of paying out medals is accompanied by some temporal fluctuation, it is not limited to the well-formed waveform as shown in FIG. If accurate determination is made including such a case, more CPU capacity is used.

  Therefore, in the embodiment of the present invention, as shown in FIG. 8, a lottery process is performed (S1), and when the winning is made (YES in S2), the rotation of the rotating disk 3 is irregular (simply, the rotation). A medal payout control signal (hopper drive signal) is generated so as to temporarily stop the disk 3 (S3) and the medal payout sensor 43 is monitored (S4), and the medal detection of the payout sensor is synchronized with the rotation of the rotating disk 3. It is determined whether or not it is done (S5), and if it is not suitable (simply detected when the rotating disk 3 is stopped) (NO in S5), it is determined that the act is illegal and error processing is performed (S6). ).

  When the process of S3 in FIG. 8 is performed, for example, a timing chart as shown in FIG. If there is a detection in any of the periods (T1, T2) in which the rotating disk 3 is stopped (if the payout sensor output signal in the figure is at the H level), it can be immediately determined as an illegal act. This is because medals cannot be paid out even when the rotary disk 3 is stopped (the medal may be detected even after the medal payout control signal is turned off due to a delay in mechanical operation or inertia). Therefore, it is preferable that a medal is not detected in a certain period (ΔT) after the control signal is turned off, so that it is not determined to be fraudulent. Actually, the maximum value of the delay is measured by measuring with a hopper device. Period (ΔT) may also be used).

  The flowchart of FIG. 8 has the following advantages. First, because of the lottery process of S1 and S2 in the figure, the fraudster cannot predict when the fraud detection will be made and cannot deal with it. This means that cheating becomes very difficult. Next, the process of temporarily turning off the medal payout control signal does not place much load on the CPU, and the process of monitoring the payout sensor output signal during the off period also places much load on the CPU. is not. Therefore, the process of FIG. 8 can be executed by the main board 200. Although the above processing is simple and its effect is great, in particular, since the capacity of the main board used in the gaming machine is limited, the processing is simple and requires a small capacity, and can be executed even with the main board. It can be said that the effect of the present invention is very large.

  As a method of rotating the rotating disk 3 irregularly, it is the simplest to turn off the medal payout control signal irregularly and temporarily, and further detailed description will be added along with this example. Is not limited to this, but includes other irregular rotational forms. These will be described later.

  10 and 11 show a flowchart of a main routine of processing for turning off the medal payout control signal irregularly and temporarily, and FIG. 12 shows a flowchart of the timer interruption processing. FIG. 13 is a timing chart for explaining the operation.

  10 to 12, the weight lottery flag is a flag for determining whether or not to execute the program wait process, and the hopper operation flag is a flag for determining whether the hopper motor drive is on or off, and a hopper stop waiting timer Is a timer for waiting for the hopper to completely stop after the hopper operation flag is turned off, and the wait timer is a timer for controlling a period during which the hopper is stopped. As these flags and timers, those with a built-in CPU can be used.

  First, FIGS. 10 and 11 will be described. When paying out, the payout process shown in the figure is performed. First, the payout number related to the winning is acquired (S11), and when the payout number is 0 (exactly when the specified number of medals are paid out, the remaining amount of the payout number becomes 0), The payout process is terminated (YES in S12). Otherwise, it is determined whether the weight lottery flag is ON (S13). The weight lottery flag will be described later. If it is ON, the process after S14 is executed (YES in S13), and if it is not ON, the process of S27 is executed (NO in S13). Whether or not a lottery for rotating the rotating disk 3 irregularly is set by a weight lottery flag. If the flag is OFF, the rotating disk 3 rotates at a constant speed as in the prior art.

  In order to make the rotation of the rotating disk 3 irregular, a random number is acquired (S14), and a payout weight lottery is performed (S15). Based on the lottery result, it is determined whether payout weight is performed, that is, whether the rotating disk 3 is rotated irregularly (S16). For example, when the acquired random number is a value within a predetermined range, a payout weight is performed. When the rotating disk 3 is rotated irregularly (YES in S16), the processes after S18 are executed. If not (NO in S16), the hopper operation flag is set to ON (S17), and the process returns to S12.

  After S18, the medal payout control signal (hopper drive signal) is turned off for a certain period. First, the hopper operation flag is set to OFF (S18). Thus, the medal payout control signal (hopper driving signal) is turned off. A hopper stop waiting timer is acquired (S19), the hopper stop waiting timer is subtracted (S20), and these are continued until the hopper stop waiting timer ends (S21).

  A wait timer is acquired (S22). This is to determine the stop period of the hopper. Note that the wait timer may be set at random. It is checked whether the payout sensor is ON (S23). If it is ON, error processing is performed (S24). For example, an alarm sound is emitted from a speaker, lighting is blinked, or an error signal is sent to a hall computer. At the same time, the operation of the gaming machine may be stopped, and the game or medal payout operation may be stopped until the hall clerk resets. If the payout sensor is not ON, the wait timer is subtracted (S25), and the processing from S23 to S25 is continued until the end of the wait timer (S26). When the wait timer ends, the hopper operation flag is set to ON (S27), and the process returns to S12.

  Next, FIG. 12 will be described. As a hopper control process, first, a hopper operation flag is confirmed (S30). If the hopper operation flag is not ON (NO in S31), the driving of the hopper motor is stopped (S36). If it is ON, driving of the hopper motor is started (S32). As a result, when the disc rotates and the medal is pushed out to the payout slot, the payout sensor detects the medal (YES in S33). In this case, the number of payouts is subtracted by the number of detections (usually one) (S34), and the weight lottery flag is set to ON (S35). When the payout sensor does not detect a medal (NO in S33), the process in FIG. 12 ends.

  FIG. 13 shows an outline of the relationship between the medal payout control signal and the output signal of the payout sensor by the processing of FIGS. According to FIG. 13, every time a single medal is paid out, the rotating disk stops for a random period, and as a result, the rotation (operation) of the hopper becomes irregular. Since whether or not to wait is also random, the weight may be irregularly entered between the payout of two medals or may not be entered at all.

  As described above, the apparatus / method according to the embodiment of the invention stops the hopper when winning the lottery and performs the weight process in the program, so that the medal payout timing can be made random. it can. During the wait process, the payout sensor is monitored. If the payout sensor continues to be on for a certain time regardless of the hopper stop state, the process proceeds to error processing as a payout abnormality. By randomizing the payout timing, when an attempt is made to obtain more than a prescribed number of game medals with a wire or the like at the time of payout, the possibility of being detected as an error is greatly increased.

Note that another method for causing the hopper device to operate irregularly will be briefly described.
As a method of making the operation irregular, the rotational speed of the disk itself is made irregular. For example, some modulation is added to the medal payout control signal. For example, pulse modulation that alternately turns on and off is performed, or analog modulation is performed on an analog signal applied to the motor.
When the disc rotation speed itself is irregular, the payout sensor is monitored by comparing the disc rotation speed with the payout sensor output signal. For example, the correlation between the two is obtained. The rotation speed is calculated from the medal payout control signal or directly measured by providing a rotation detector such as a rotary encoder on the rotating disk.

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