  The game area 20 is provided with a game nail and a windmill (both not shown) that change the direction in which the game ball falls downward. Further, in the game area 20, various bonuses related to winning and lottery are arranged at predetermined positions. In FIG. 1, as an example of various prizes related to winning and lottery, a first starting port 25a, a second starting port 25b, a gate 27, a big winning port 28, and a normal winning port 29 are arranged on the game board 2. It is installed. Further, the game area 20 is provided with a discharge port 24 for discharging out of the game area 20 a game ball that has not been won in the winning area among the game balls launched into the game area 20.

  The first start opening 25a and the second start opening 25b each receive a prize when a game ball enters, and a special symbol lottery (a jackpot lottery) is started. The first starting port 25a is a winning port for winning a game ball, which activates a predetermined special electric accessory (large winning port 28) and / or a predetermined special symbol display. The second starting port 25b is a winning port related to winning a game ball that activates the special electric accessory (large winning port 28) and / or a predetermined special symbol display. When the game ball passes through the gate 27, a normal symbol lottery (open / close lottery) is started.

  The 2nd starting opening 25b is provided in the lower part of the 1st starting opening 25a, and is provided with the electric tulip 26 near the entrance of a game ball as an example of a normal electric accessory. The electric tulip 26 has a pair of wings imitating tulip flowers, and the pair of wings opens and closes left and right by driving an electric tulip opening / closing unit 112 (for example, an electric solenoid), which will be described later. Lights up or blinks together. When the pair of blade portions are closed, the electric tulip 26 is in a state in which the game ball does not enter the second starting port 25b because the opening width guided to the inlet of the second starting port 25b is extremely narrow. On the other hand, the electric tulip 26 is configured such that when the pair of blade portions are opened to the left and right, the opening width guided to the inlet of the second starting port 25b increases, so that the game ball can easily enter the second starting port 25b. Has been. When the electric tulip 26 wins the normal symbol lottery by passing a game ball through the gate 27, the pair of blades open for a specified time (for example, 0.15 seconds or 1.80 seconds) while lighting or flashing. Open and close a specified number of times (for example, once or three times).

  The special winning opening 28 is located below the second start opening 25b and opens according to the result of the special symbol lottery. The special winning opening 28 is normally in a closed state so that no game balls can enter, but depending on the result of the special symbol lottery, it protrudes from the main surface of the game board 2 and is in an open state. The game ball is easy to enter. For example, the grand prize winning opening 28 is a predetermined number of rounds (for example, 29.5 seconds elapses or until 10 game balls have been won or the accumulated cumulative time is within 1.8 seconds). , 15 times or once). Further, the lottery does not start at the normal winning opening 29 even if a game ball wins.

  In addition, a display 3 is provided at a predetermined position (for example, lower right) of the game board 2 to display the result of the above-described special symbol lottery or normal symbol lottery and the number of holds.

  The gaming machine 1 shown in FIG. 1 has two first start openings 25a and second start openings 25b in the game area 20, but when a game ball enters, a special symbol lottery is started. Only one starting port may be provided.

For example, the gaming machine 1 has a state in which the jackpot probability is relatively low (low probability state; for example, the jackpot probability is 1/300) to a state in which the jackpot probability is relatively high (high probability state; for example, the jackpot probability is 30 May fluctuate to 1). In addition, the gaming machine 1 can reduce the special symbol fluctuation time at the time of the special symbol lottery under a predetermined condition, increase the probability of winning at the time of the normal symbol lottery, or reduce the normal symbol fluctuation time at the time of the normal symbol lottery. In some cases, the opening time of the blade portion of the electric tulip 26 is extended, or the number of times the blade portion of the electric tulip 26 is opened and closed increases (electric chew support).

  Here, the payout of prize balls will be described. When a game ball enters the first start port 25a, the second start port 25b, the big winning port 28, and the normal winning port 29 (winning), a predetermined number per game ball is determined according to the place where the game ball has won. Prize balls are paid out. For example, when a game ball wins the first start port 25a and the second start port 25b, four prize balls are awarded, and when a game ball wins the big prize port 28, thirteen prize balls are awarded, and the game ball wins the normal prize opening 29. Then, 10 prize balls are each paid out. Even if it is detected that the game ball has passed through the gate 27, there is no payout of the prize ball in conjunction with it.

  The frame member 5 on the front surface of the gaming machine 1 includes a handle 51, a lever 52, a stop button 53, a take-out button 54, a speaker 55, a frame lamp 56, an effect button 57, an effect key 58, a dish 59, a lock part 43, and the like. Is provided.

Electric fire the ball. The tray 59 is provided so as to protrude in front of the gaming machine 1 and temporarily stores game balls to be supplied to the launching device. In addition, the above-described prize ball is paid out to the plate 59. Then, the game balls stored in the tray 59 are supplied to the launching device one by one by a supply device (not shown) at a timing interlocked with the operation by the player's lever 52. In addition, the plate 59 may be configured by integrating the upper and lower plates, or may be configured by separating the upper plate and the lower plate. The handle 51 may emit light under predetermined conditions.

  The stop button 53 is provided on the lower side surface of the handle 51, and even when the player touches the handle 51 and rotates the lever 52 in the clockwise direction, the game ball is released by being pressed by the player. Is temporarily stopped. The take-out button 54 is provided on the front surface in the vicinity of the position where the tray 59 is provided. When the player presses the game ball, the game ball stored on the tray 59 is dropped into a box (not shown).

  The speaker 55 and the frame lamp 56 respectively notify the gaming state and situation of the gaming machine 1 and perform various effects. The speaker 55 performs various effects using music, voice, and sound effects. Further, the frame lamp 56 performs various effects by light depending on a pattern by lighting / flashing, a difference in emission color, or the like. Note that the frame lamp 56 may change the light irradiation direction and produce an effect by changing the irradiation direction.

  Next, with reference to FIG. 2, the movement of the illegal game ball launched by the launching device will be described. FIG. 2 is a schematic diagram for explaining an example of the movement of an unauthorized gaming ball launched by the launching device of the gaming machine 1. In FIG. 2, only the gaming area 20, the first starting port 25 a, the inner rail 61, the outer rail 62, and the launching ball passage 63 among the constituent members constituting the gaming machine 1 are shown for simplicity of explanation. Show.

  In FIG. 2, when a player supplies an unauthorized gaming ball to which a thin line is bonded to the gaming machine 1 and performs a launch operation with the launching device, the unauthorized gaming ball is launched in the game ball firing direction. The illegal gaming ball launched by the launching device moves upward along the front surface of the game board 2 through the launching ball passage 63 formed between the inner rail 61 and the outer rail 62 in the direction A in the figure. Move like a rogue gaming ball. Then, the illegal game ball launched into the launch ball passage 63 is released from the launch ball passage 63 above the game area 20. Then, the game ball released to the upper side of the game area 20 moves freely falling along the front surface of the game board in the game area 20 like an illegal game ball moving in the direction B in the figure.

  Unauthorized game balls launched into the game area 20 may naturally enter an accessory (for example, the first start opening 25a) from which prize balls are paid out. It is also possible for a player who operates the other end of the thin line with one end attached to the unauthorized gaming ball to illegally guide the unauthorized gaming ball to enter the accessory by operating the thin line. . Then, the illegal game ball that has entered the game object to which the prize ball is paid out is detected by a sensor that detects that the game ball has entered the game object when the player inserts or removes the thin line into the game machine 1. It is operated so as to reciprocate from the inside to the outside of the detection region and from the outside of the detection region to the inside of the detection region (for example, reciprocation within the path after entering the first start port 25a shown in the direction C in the figure). The control unit of the gaming machine 1 that acquires the detection result because the sensor that detects that the game ball has entered the accessory due to the unauthorized operation outputs the same detection result as when a plurality of game balls are won. Pays out a prize ball according to the detection result. Moreover, when the said accessory is a starting port for starting a special symbol lottery (a jackpot lottery), the control unit of the gaming machine 1 that acquires the detection result starts the special symbol lottery according to the detection result. .

  Next, with reference to FIGS. 3 to 5, a fraud prevention mechanism provided in the gaming machine 1 will be described. FIG. 3 is a longitudinal sectional view showing an example of the overall configuration of the fraud prevention mechanism provided in the gaming machine 1. FIG. 4 is a diagram illustrating an example of the path 70 and the protrusion 71 viewed from the direction D in FIG. FIG. 4 is a diagram illustrating an example of the path 70 and the protrusion 71 viewed from the direction E in FIG.

  In FIG. 3, the anti-fraud mechanism provided in the gaming machine 1 may be an accessory (for example, a first start opening 25a, a normal winning opening 29, a second starting opening 25b, a big winning opening 28, etc.) from which prize balls are paid out. However, typically, the game balls that have entered the first start opening 25a and the normal winning opening 29) are provided on the path 70 through which they pass. The fraud prevention mechanism includes a protrusion 71 and a detector 72. The protrusion 71 is provided in a path 70 through which the game ball that has entered the above-mentioned accessory passes. And the protrusion part 71 protrudes from the direction which cross | intersects the path | route 70, and as shown by the white arrow in the figure, the track | orbit (path | route 70) of the game ball | bowl which passes through the path | route 70 is bent in the said protrusion direction. The game ball that has entered the above-mentioned accessory is passed.

  The detection unit 72 detects a game ball passing through the path 70 bent by the protrusion 71 in the path 70. As an example, the detection unit 72 forms the detection area DA of the detection unit 72 in the path 70 formed along the lower surface of the protrusion 71. In this case, the detection unit 72 detects a game ball passing through the path 70 along the lower surface of the projection 71 from the distal end 71t of the projection toward the base end 71b. For example, the detection unit 72 includes a proximity sensor (proximity switch) that can detect a game ball passing through the detection area DA, a photo sensor, an optical sensor, and the like, and detects a game ball passing through the detection area DA. Then, a signal indicating the detection is output to the control unit of the gaming machine 1. And the said control part can know that the game ball won the said accessory by acquiring the signal which shows having detected the game ball from the detection part 72. FIG.

  The detailed structural example of the protrusion part 71 is demonstrated using FIG. 4 and FIG. The protrusion 71 is convex in the direction from the base end 71b to the tip 71t, and is formed in a comb-teeth shape with a gap narrower than the diameter of the game ball. Between the protrusions formed in a comb-like shape, it is formed from the tip 71t toward the base end 71b along the direction in which the game ball passes through the bent path 70, and the inside of the protrusion 71 is vertically (for example, A plurality of grooves (gap) penetrating in the D direction shown in FIG. 3 are formed. Specifically, the opening width of the groove is set to be narrower than the diameter of the game ball passing through the path 70 and wider than the diameter of the wire assumed to be attached to the unauthorized game ball.

  Next, with reference to FIGS. 3 to 5, an example of a mechanism in which fraud using a fraudulent game ball attached with a thin line is prevented by the fraud prevention mechanism will be described.

  As shown in FIG. 3, when the illegal game ball with the thin line attached enters the above-mentioned accessory, the illegal game ball passes through the path 70 and reaches the vicinity of the protrusion 71. Thereafter, the illegal game ball reaches the detection area DA of the detection unit 72 through the path 70 bent by the protrusion 71, that is, along the path of the white arrow shown in FIG. At this time, in order for a player (illegal person) who operates the thin line of the illegal game ball to repeat the winning of the above-mentioned bonus item using the illegal game ball, the illegal game ball is detected from the detection area DA to the detection area DA. It is necessary to operate so as to reciprocate from outside and outside the detection area DA into the detection area DA. Here, as shown in FIGS. 3 to 5, when an illegal game ball is made to enter the vicinity of the detection area DA through a path 70 bent by the protrusion 71, the illegal game ball is placed on the lower surface of the protrusion 71. Therefore, the thin line attached to the illegal game ball enters into any of the grooves formed in the protrusion 71. Therefore, the unauthorized person performs an operation of repeatedly winning the bonus item in a state where the thin line enters the inside of the groove formed in the protruding portion 71. However, even if an operation of pulling up the thin line in a state where the thin line enters the inside of the groove formed in the protruding portion 71, the illegal game ball is not attached to the lower surface of the protruding portion 71 as shown in FIGS. Since it is lifted upward in the contact state, the illegal game ball cannot be lifted and moved so as to be retracted in the path 70. In other words, an unauthorized person cannot manipulate the illegal game ball so as to reciprocate from the detection area DA to the outside of the detection area DA and from the outside of the detection area DA to the detection area DA. Will be prevented.

  As described above, according to the gaming machine of the present invention, when a fraud using an illegal game ball with a wire rod attached is performed, the protrusion 71 can prevent the fraud.

  In the example of the fraud prevention mechanism shown in FIG. 3, the lower surface of the projecting portion 71 is used in the direction in which the game ball travels. However, the lower surface may be formed in other shapes. Absent.

  As a first example, as shown in FIG. 6, the lower surface of the projecting portion 71 is leveled or raised in the direction of travel of the game ball (that is, tilted in the horizontal or depression direction with reference to the position of the bottom surface at the base end 71b). ). In any case, when the illegal gaming ball once enters the path 70 formed along the lower surface of the protruding portion 71 and then pulls up the thin line, the illegal gaming ball becomes the tip 71t of the protruding portion 71. Since it becomes more difficult to move to the side, the above-described unauthorized operation can be reliably prevented.

  As a second example, as shown in FIG. 7, a recess 71 c may be formed on a part of the lower surface of the protrusion 71. Accordingly, when the illegal game ball once enters the path 70 formed along the lower surface of the protruding portion 71 and then the fine line is pulled up, the illegal game ball is formed in the concave portion 71c formed on the lower surface of the protruding portion 71. Since it gets stuck and it becomes difficult to move further to the tip 71t side, the above-mentioned unauthorized operation can be surely prevented.

  In the example of the fraud prevention mechanism shown using FIG. 3, the detection unit 72 is arranged at a position where the detection area DA is formed in the path 70 formed along the lower surface of the projection 71. As long as the game ball passing through the path 70 bent by the unit 71 can be detected, the detection unit 72 may be arranged at another position. As an example, the detection unit 72 is arranged at a position where the detection area DA is formed in the path 70 formed along the tip 71t of the protrusion 71 in the path 70 bent by the protrusion 71. Even if the detection unit 72 is disposed at this position, the illegal game ball enters the path 70 formed along the tip 71t of the protrusion 71 or the path 70 formed along the lower surface of the protrusion 71. In such a case, since it can be expected to enter the inside of any of the grooves formed in the protruding portion 71, it is possible to expect the effect of preventing the above-described unauthorized operation.

  As another example, the detection unit 72 is arranged at a position where the detection area DA is formed in the path 70 formed along the upper surface of the protrusion 71 in the path 70 bent by the protrusion 71. Even if the detection unit 72 is arranged at this position, depending on the unauthorized person's fine line operation, the illegal game ball is formed in the path 70 formed along the tip 71t of the projection 71 or along the lower surface of the projection 71. In such a case, it can be expected to enter the inside of one of the grooves formed in the protruding portion 71, thus preventing the above-described unauthorized operation. The effect can be expected.

  Further, in the example of the fraud prevention mechanism shown using FIGS. 3, 6, and 7, the exit path (path 70) that exits from the path 70 bent by the protrusion 71 is the bent path 70. Although it is provided at a position immediately below the approach route (route 70) to enter, the exit route may be provided at another position with respect to the approach route. As an example, the exit path that exits from the path 70 bent by the protrusion 71 may be provided at a position that exits downward from the middle of the path 70 formed along the lower surface of the protrusion 71.

  Moreover, in the example mentioned above, although the several groove | channel is formed in the protrusion part 71, what is necessary is just to form the said groove | channel at least. For example, even when a single groove is formed in the protruding portion 71, it can be expected that a thin line attached to the unauthorized gaming ball enters the groove, and thus the effect of preventing unauthorized operation as in the above-described example. Can be expected.

  Moreover, you may form the corner | angular part of the opening part 71t side opening part of the groove | channel formed in the protrusion part 71 in a taper shape or a circular arc shape. Thus, by making the opening angle part of a groove into a taper shape or a circular arc shape, since the thin line attached to the unauthorized game ball easily enters the groove, the effect of preventing the above-described unauthorized operation can be enhanced.

  In addition, the shape, number, installation position, and the like of each component provided in the gaming machine 1 described above are merely examples, and the present invention can be realized even with other shapes, numbers, and installation positions. Needless to say.

  Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit the scope thereof. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. It is understood that the scope of the present invention should be construed only by the claims. Moreover, it is understood that those skilled in the art can implement an equivalent range from the description of the specific embodiments of the present invention based on the description of the present invention and the common general technical knowledge. In addition, it is to be understood that the terms used in the present specification are used in the meaning normally used in the art unless otherwise specified. Thus, unless defined otherwise, all technical and technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In case of conflict, the present specification, including definitions, will control.

  Hereinafter, the function and effect of the embodiment will be described. In interpreting the description of the scope of claims, it is understood that the scope should be interpreted only by the description of the scope of claims. In case of conflict, the claims will prevail. In addition, the description in parentheses in this operational effect indicates a correspondence relationship with the above-described embodiment in order to help understanding of the present invention, and does not limit the scope of the present invention.

  In the said embodiment, the path | route (path | route 70) of a game ball, the protrusion part (protrusion part 71), and the detection part (detection part 72) are provided. The projecting portion is provided so as to project from the direction intersecting the route in the route, and bends the trajectory of the game ball passing through the route. A detection part detects the game ball which passes the track | orbit bent by the protrusion part in the said track | orbit. The protrusion is formed from the tip (tip 71t) to the base (tip 71b) of the protrusion along the direction in which the game ball passes through the track, and the protrusion is formed with a gap narrower than the diameter of the game ball. At least one groove penetrating in the vertical direction is formed.

  According to the above, when a fraud using an illegal game ball with a wire rod attached is made, the fraudulent game ball cannot be lifted when the wire rod enters the groove, so that the fraud can be prevented.

  The protrusion may be formed in a comb-like shape in which a direction from the base end to the tip is convex by forming a plurality of grooves.

  According to the above, since it becomes easy for the wire rod attached to the unauthorized gaming ball to enter the groove of the protruding portion formed in a comb-teeth shape, the unauthorized operation can be reliably prevented.

  The lower surface of the protrusion may be formed to be inclined in the horizontal or depression direction with reference to the position of the lower surface at the proximal end.

  According to the above, since the illegal game ball that has entered the path formed below the projecting portion is more difficult to move to the tip side of the projecting portion, the cheating can be reliably prevented.

  At least one recess (recess 71c) may be formed on the lower surface of the protrusion.

  According to the above, since the illegal game ball that has entered the path formed below the projecting portion gets stuck in the recess and is less likely to move to the tip side, it is possible to reliably prevent the illegal act.

  As a first example, the detection unit may detect a game ball passing through a track formed below the protrusion, among the tracks bent by the protrusion. As a second example, the detection unit may detect a game ball that passes through a track formed along the tip of the protrusion, among the tracks bent by the protrusion. As a third example, the detecting unit may detect a game ball passing through a track formed above the protruding portion among the tracks bent by the protruding portion.

  According to the above, the unauthorized person cannot operate the unauthorized gaming ball so as to reciprocate from the detection area where the detection unit detects the gaming ball to the outside of the detection area and from the detection area to the detection area.
