The mainstream is to operate the variable display device so that the display is stopped after the operation.

  The variable display device has an opening for allowing a pachinko ball (game ball) to flow in. The game ball that has flowed into the variable display device from this opening falls downward through a stage formed in the lower portion of the variable display device. Let A start winning opening is formed below the variable display device, and when the game ball enters the start winning opening and wins, the symbol display device operates. When the winning prize opening is won, the symbol display device performs variable display of symbols in a plurality of display areas for sequentially displaying a plurality of types of symbols. Whether or not to shift to the jackpot mode is determined by a jackpot determination lottery performed in response to winning at the start winning opening.

  When “hit” is won in this jackpot determination lottery, a combination of symbols constituted by specific symbols is displayed in each display area, and at least the right to shift to the jackpot mode is obtained. A big prize opening is provided in the back of the attacker provided in the game area. When the jackpot mode is entered, the attacker operates repeatedly up to a certain number of times on condition that the continuation condition is satisfied, with one round from the opening to closing of the winning prize opening. In one round, the attacker closes the big prize opening after, for example, 30 seconds elapses or ten game balls are won after opening the big prize opening. When shifting to such a jackpot mode, the player can win a larger number of game balls than usual at the big prize opening, and can acquire a large number of prize balls.

The provided ball passage detector 20g and the vibration sensor VS are provided later.

  FIG. 5 is a schematic front view of the variable display device 30a of the gaming machine according to the embodiment of the invention. Reference numeral 30a in FIG. 5 denotes a variable display device called a so-called bladed object (in the following description, the variable display device 30a may be referred to as an accessory of a bladed object, or simply a bladed object or an accessory). In the variable display device 30a, when a game ball enters the start winning opening 30d, the variable winning portion 142 is temporarily opened.

  The variable display device 30a includes a surrounding wall member 141 formed so as to isolate a gaming area and a winning space around the winning space in order to form a winning space therein. Furthermore, a variable winning portion (electric component) 142 provided respectively on the left and right side surfaces of the upper portion of the peripheral wall member 141, a specific region (V winning region) 143 formed in the winning space, and a general region 144 Have.

  The variable winning portion 142 includes movable pieces 146 and 146 on the left and right, respectively. These movable pieces 146 and 146 are opened and closed by a solenoid coil (not shown). The solenoid coil is controlled by the control unit 40.

  In FIG. 5, dotted lines indicate the movable pieces 146 and 146 in the open state. In the open state, the variable winning portion 142 is opened, and a winning opening that communicates from the game area around the winning space to the winning space of the variable display device 30a appears. That is, the left and right movable pieces 146, 146 are almost upright and closed so that the game ball cannot be won in the winning space of the variable display device 30a, and the left and right movable pieces are opened diagonally to the left and right, respectively. Can be in any open state that allows winning (inflow).

  In addition, a winning opening (opening) of the variable winning portion 142 in the open state of the movable pieces 146, 146 is provided with a sensor (reference numeral 20f in FIG. 6) of a blade object (not shown). It is detected that a game ball has won (inflowed) and outputs a detection signal to the control unit 40.

  When the sensor 20d of the start chucker 30d detects the winning of the game ball and outputs the detection signal to the control unit 40, the control unit 40 performs a process of paying out the game ball (prize ball) for the winning and the movable piece 146. , 146 to output a control signal to release the closed variable display device 30a (variable winning portion 142) for a predetermined time (1 second) (general gaming machine) Then, control is performed to perform once or twice).

  Next, an internal configuration below the variable winning units 142 and 142 of the variable display device 30a will be described. General regions (OUT regions) 144 and 144 are provided on the left and right sides of the inner space of the variable display device 30a below the variable prize winning portions 142 and 142, and the center between these general regions 144 and 144 is provided. A specific area (V winning area) 143 is provided in the section.

  The specific area 143 is provided with a V winning ball detection sensor (not shown) that detects that a game ball has flowed into (passed through) the specific area 143. A V winning ball detection sensor (not shown) is connected to the control unit 40. When receiving a detection signal from a V winning ball detection sensor (not shown), the control unit 40 performs a process of generating a hit state.

  The general areas 144 and 144 are each provided with an OUT ball detection sensor (not shown) that detects that a game ball has flowed into (passed through) the areas.

  The V winning ball detection sensor and the OUT ball detection sensor are collectively referred to as a blade outlet sensor (reference numeral 20g in FIG. 6).

  Further, a rolling portion is provided between the variable winning portion 142 in the internal space of the variable display device 30a, the specific region 143, and the general regions 144 and 144. In the example of FIG. 5, the rolling portion includes two triangular roof-like structures having a high central portion and low left and right side portions, and these are arranged symmetrically. The triangular roof-like structure includes a roof portion 181 that is inclined toward the outside of the variable display device 30a, and a linear shape that has one end in contact with the lower end of the roof portion 181 and the other end extending downward. An outer side surface 182 and a linear inner side surface 183 having one end in contact with the upper end of the roof portion 181 and the other end extending downward are provided.

  The game ball entered from the winning opening of the variable winning portion 142 first contacts the roof portion 181 and jumps or rolls on the roof portion 181. The behavior of the game sphere there is different for each game sphere and moves in a complicated manner. Some game balls climb the roof portion 181 and fall down the passage between the inner side surfaces 183 and 183, and enter a specific area 143 provided below them (the symbols Q1 and Q2 in FIG. Shows the path of the game ball.) Many game balls descend the roof portion 181, fall down a passage between the inner side and the outer side surface 182 of the surrounding wall member 141, and are received by the curved portion 186, and then enter the general region 144 from the end to be lost ( The symbols P1 and P2 in FIG. 5 indicate the path of the game ball at that time).

  Since the behavior of the game ball on the roof portion 181 separates the win from the win, it is of interest to the player. Some players try to move a game ball and hit it by hitting a gaming machine.

  FIG. 6 is a block diagram of fraud determination processing according to the embodiment of the present invention.

  In the figure, 20f is a sensor at the entrance of the blade, 20g is a sensor at the exit of the blade, and VS is a vibration sensor provided in the gaming machine.

  The sensor 20f at the blade entrance is a sensor provided at the winning opening of the variable winning section 142 as described above. The sensor is equivalent to the other sensors 20a to 20e. The sensor 20f at the blade entrance detects that the game ball has entered the winning area of the variable display device 30a.

  The blade outlet sensor 20g is a sensor provided in the specific area 143 and the general areas 144 and 144 as described above (if it can be detected that the exit from the winning area of the variable display device 30a is another place) It may be provided at the place). The sensor is equivalent to the other sensors 20a to 20e. The feather exit sensor 20g detects that the game ball has exited the winning area of the variable display device 30a.

  The vibration sensor VS is a known sensor, and a sensor that uses a piezoelectric element and electrically detects the vibration by converting the vibration applied from the outside into a voltage by the piezoelectric effect is known. There are other capacitance type and eddy current type. The vibration sensor VS itself is well known and will not be described in detail. The vibration sensor VS in FIG. 6 detects vibration generated by the player hitting the gaming machine housing, particularly the opening frame door 52 thereof.

  As shown in FIG. 7, the vibration sensor VS is provided, for example, on the back surface of the opening frame door 52 and the panel surface 11 inside the variable display device 30a (in the figure, three vibration sensors are shown, but any one of them is provided). Good). When a vibration above a certain level is detected by the vibration sensor VS, it may be considered that the gaming machine has been hit by the player. FIG. 7 shows a cross-sectional view when the gaming machine is installed in a hall or the like and cut along a vertical plane that passes through the center of the gaming machine and is orthogonal to the board surface.

  Reference numeral 40c in FIG. 6 denotes an illegal act determination unit that determines an illegal act based on the outputs of the sensors 20f, 20g, and VS, specifically, an act of hitting a gaming machine. The cheating determination unit 40c is realized by a CPU mounted on the control unit 40 executing a predetermined program. Therefore, a CPU (not shown) of the control unit 40 executes the following processing.

  FIG. 8 is a flowchart of the fraud determination process according to the embodiment of the invention. In accordance with the same figure, the cheating determination process of the gaming machine according to the embodiment of the present invention will be described.

S20: The output of the blade inlet sensor 20f is monitored.

S21: It is determined whether or not the game ball has entered the winged object.
When the sensor 20f detects the game ball, it is determined that the game ball has entered the winged object (inside the variable display device 30a), and the processing from S22 onward is executed. Detection of the sensor 20f serves as a trigger for executing fraud determination.

S22: The number of detections is set to 0 (the number of detections is initialized).

S23: The detection of the vibration sensor VS is started.
Until S23 is executed, the vibration sensor VS is disabled, and even if the output is sent to the fraud determination unit 40c, it is ignored.

S24: It is determined whether or not the game ball has come out of the winged object.
The output of the sensor 20g at the exit of the blade is monitored, and when it detects a game ball, it is determined that the game ball has come out of the accessory of the blade. When the sensor 20g fails to detect, a timer (not shown) is activated when YES is obtained in S21, and when the timer passes a certain time (for example, 30 seconds), the game ball is shuffled as a time-out. You may make it consider that it came out of the inside of a thing's role. Note that the output of the sensor 20g and the timer may be used together, and it may be determined that the game ball has come out of the winged object when one of the above conditions is satisfied.

  When the game ball comes out of the feature of the feather (YES in S24), the execution of the fraud determination is stopped. That is, the period from YES in S21 to YES in S24 is a period in which vibration is detected for fraud determination. After executing the fraud determination, a determination is made based on the number of detections (S24-).

S25: It is determined whether or not the vibration sensor has detected.
When it is not determined that the game ball has come out of the winged object (NO in S24), when vibration is detected by the vibration sensor VS (YES in S25), 1 is added to the number of detections.

  Specifically, when the output of the vibration sensor VS exceeds a predetermined threshold TH, it is assumed that there is one detection, and 1 is added to the number of detections. The threshold TH may be determined according to, for example, vibration (background noise) that is normally generated. For example, when the output of the vibration sensor VS is monitored in a hall in operation and the average value is A, the threshold value TH is M × A. Here, M is a margin, for example, M = 1.5 or M = 2.

  When there are many pulse-like vibrations with a short duration as the background noise, the duration may be viewed together. A threshold value THT (for example, 100 mS) relating to the duration time is determined. Then, when the output of the vibration sensor VS exceeds the threshold value TH and the time when the output exceeds the threshold value TH exceeds the threshold value THT, 1 is added to the number of detections. In this way, even if the margin M is reduced to be close to 1, it is difficult for the number of detections to increase due to noise.

  By the processing of S22 to S26, the number of times that the vibration sensor VS has detected from when the game ball enters the accessory (variable display device 30a) until it exits can be obtained.

S27: The detection of the vibration sensor is terminated.

S28: It is determined whether or not it is an illegal act according to the number of times the vibration sensor VS is detected.
Two threshold values (threshold value 1 and threshold value 2) are prepared in advance. It is assumed that threshold 1 <threshold 2.
Only when the threshold value 1 ≦ the number of detections ≦ the threshold value 2 is determined to be an illegal act (S29c). Other than this, the detected vibration is determined to be noise and is not determined to be fraudulent (S29a, S29b).

  When it is determined that the act is illegal, the fact is transmitted to the hall computer, and an error is notified in the gaming machine, or the gaming machine cannot be played.

  The determination as in S28 to S29c is based on the following reason.

The player hits the gaming machine, for example, when the game ball enters the inside of the accessory and rolls on the roof 181. By hitting the game ball from the outside, the player can hit the game ball with reference numerals Q1 and Q2 in FIG. This is to allow the route to pass through. Therefore, it is preferable to detect the vibration during a period from when the game ball enters the inside of the accessory until it exits.

-It takes a certain amount of time for the game ball to fall down after being placed on the roof 181. It is considered that the player hits the gaming machine at the time, but continuously hits until the game ball follows a desired route. It is hard to think of hitting it once (it is a snake foot, but it is not impossible to hit it only once. This is not to induce a game ball, but to hit a gaming machine in a way that you can not play as you think The embodiments of the present invention are not intended to detect such actions). Therefore, the number of times that the player is expected to hit in the above case (for example, 2 to 3 times) is set as the threshold 1, and the number of detections is more than this.

-The time from when the game ball is placed on the roof 181 until it falls down is relatively short, and there is a limit to the number of times the player can hit it. Therefore, the number of times (for example, 4 to 5 times) that the player can hit in the above case is set as the threshold 2 and the number of detections is less than this. When the threshold value 2 is exceeded, it is considered that it is not caused by the player's action but by disturbance (noise) such as machine vibration.

  According to the embodiment of the invention, (1) the number of times of detection of the vibration sensor is measured from when the game ball enters the inside of the accessory until it exits, and (2) the number of times of detection is two thresholds 1 and Only when two conditions of being between the threshold values 2 are satisfied, it is determined to be an illegal act. Therefore, determination with high accuracy is possible. Even if a highly sensitive vibration sensor is used, noise is not erroneously determined as an unauthorized act, and the use of the highly sensitive vibration sensor can increase the probability of detecting an unauthorized act. In short, the erroneous determination rate can be lowered while increasing the detection probability.

  According to the embodiment of the invention, even if the player tries to hit the gaming machine and put the game ball into the winning opening, such an attempt is made by detecting the action and performing error notification or stopping the game. Can be failed. The player can realize that an illegal act is useless, and can thereby deter the act of hitting a gaming machine.

  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.
