Description

  The present invention relates to a lottery device used in a medal game machine, for example.

  Some so-called arcade-type medal game machines installed in game centers or the like cause a game to be played by inserting medals into a predetermined medal game field. In such a medal game machine, not only a simple game is advanced using medals but also a lottery game using a ball is performed according to the progress of the medal game, thereby complicating the game, There is one that enhances its interest (see, for example, Patent Document 1).

  The medal game machine disclosed in Patent Literature 1 is provided with a lottery device (center lottery device 2000) that executes a lottery game when a predetermined condition is satisfied. As shown in FIG. 1 and FIG. 2 of Patent Document 1, the lottery apparatus includes an annular member (rotating member 2120) that constitutes a plurality of winning holes (holding spaces F). It rotates at a constant speed around a predetermined axis while maintaining an inclined posture. On the outer periphery of the annular member, a groove-shaped inclined surface (conveyance slope 2600) for moving a ball (large lottery ball 2400) as a lottery medium is provided. When a lottery game is performed, a ball is thrown from a predetermined position with respect to the inclined surface. The ball rolls on the inclined surface by its own weight and performs a pendulum motion around the lowest point of the inclined surface. When the moving speed of the ball gradually decreases and the swing width of the ball decreases until it reaches the vicinity of the lowest point of the slope, the ball enters one of the plurality of winning holes. Then, the player is awarded a prize according to the winning opening in which the ball has entered.

  However, in the above-described conventional configuration, the ball moves only in a pendulum motion during the lottery game, and thus the movement of the ball is monotonous. For this reason, the player can predict the timing when the ball enters the winning opening as the lottery game is repeatedly experienced. Therefore, there is a tendency that the degree of expectation and the degree of excitement in the ball movement process tend to decrease, and the player may get bored.

For this reason, when the lottery medium on the inclined surface in the inclined field moves to the lower side toward the opening, the lottery medium repelling mechanism may be repelled toward the higher position of the inclined surface, causing irregular movement. do. Then, the residence time of the lottery medium in the inclined field changes without being constant, and the timing at which the lottery medium passes through the opening also varies. Thus, for example, whether or not the lottery game is won in a configuration in which the winning of the lottery game (for example, the state of entering the winning hole) and the non-winning state (for example, the state of not entering the winning hole) are switched depending on the timing of passing through the opening. It is difficult for the player to predict. In addition, when the winning opening is periodically moved with respect to the opening, the player cannot easily predict whether or not the lottery medium is inserted into the focused winning opening. Therefore, according to the above configuration, the player can enjoy the lottery game by moving the lottery medium while maintaining the degree of expectation and excitement, and the interest as a lottery device can be enhanced. Furthermore, the mode in which the lottery medium moves irregularly on the inclined surface can be enjoyed visually, and the interest as a lottery apparatus is enhanced from this viewpoint.

If the lottery medium repelling member is formed of an elastic member, the lottery medium can be efficiently repelled with an appropriate resilient force. Further, even if the lottery medium is repeatedly repelled by the rotating body, it is possible to prevent a problem that the lottery medium is damaged.

  In a preferred embodiment, the lottery medium repelling members of the pair of rotating bodies are provided so that the size of the gap when closest to each other is smaller than that of the lottery medium.

  According to such a configuration, the lottery medium is easily played by the lottery medium repelling member, and moves more irregularly. In addition, since the lottery medium repelling member is made of an elastically deformable elastic member, even if the size of the gap when the lottery medium repelling members are closest to each other is smaller than the lottery medium, the lottery medium By bending the repelling member, it is possible to prevent the inconvenience that the lottery medium is sandwiched between the lottery medium repelling members.

  In a preferred embodiment, there is provided a loading mechanism for loading the lottery medium at a high position on the inclined surface.

  In a preferred embodiment, the restricting portion includes an elastic body that can play the lottery medium.

  According to such a configuration, the lottery medium is irregularly moved by being played by the restricting unit.

  In a preferred embodiment, it is configured to perform two or more types of lottery in which the content of the prize at the winning opening is changed, and according to the change in the contents of the prize at the winning opening, At least one of the rotation speeds can be changed.

  According to such a configuration, it is possible to effectively produce a plurality of lottery games while using a common lottery device.

  In the present embodiment, the blades 75b of the left and right rotating bodies 75L and 75R have a gap size g2 when they are closest to each other smaller than the diameter d1 of the ball b3.

  In the present embodiment, the pair of left and right rotating bodies 75L and 75R have different rotational directions and rotational speeds. Regarding the rotation direction of the rotating bodies 75L and 75R, the left rotating body 75L rotates counterclockwise, and the right rotating body 75R rotates clockwise. As a result, the ball b3 can be appropriately replayed toward the upper side of the inclined field 73. Regarding the rotational speeds of the rotating bodies 75L and 75R, for example, the left rotating body 75L is 60 rpm, while the right rotating body 75R is 70 rpm.

  At the time of the lottery game in the center lottery device 7, the central housing 70 controls the motor (not shown) of the microcomputer 9 so that the tilt direction of the tilt field 73 and the winning table 74 faces the front direction of the player who performs the SJP lottery. Is appropriately rotated. The winning table 74 is appropriately rotated by the microcomputer 9 controlling the motor 703. Here, the rotational speed of the winning table 74 is, for example, about 13 seconds / rotation (about 5 rpm).

  Then, the ball b3 at the standby position is released to the rolling field 71. Here, the rotating bodies 75L and 75R start the rotating operation by the microcomputer 9 controlling the motor 75c simultaneously with the releasing operation of the ball b3. The ball b3 rolls on the rolling field 71, the rail 72, and the inclined field 73, passes through the opening 73d, and enters one of the pockets 74a. Here, the sensor detects which pocket 74a the ball b3 has entered, and an award corresponding to the pocket 74a is given to the player. The rotating bodies 75L and 75R stop rotating after the sensor detects the ball b3. Next, for example, the winning table 74 is rotated about half a round, and the pocket 74a containing the ball b3 is disposed in the upper back, whereby the ball b3 is dropped and collected in the central housing 70. The collected ball b3 is returned to the standby position again by the lift mechanism 76 shown in FIG. 8, for example.

  The medal payout mechanism is for paying out the medal m on the medal game field MF of the corresponding player after the lottery game (SJP lottery) in the center lottery device 7 is completed. Although not shown in detail in the drawings, the medal payout mechanism is stored on the back side of the main display 8 at normal times, for example, and is extended downward to be directly below the medal game field MF when paying out medals. It is configured to form. At the time of paying out medals, medals m are supplied onto the medal transport path from bowls (not shown) provided at both upper ends of the main display 8.

  In the center lottery apparatus 7 of the present embodiment, a ball rebound mechanism 75 (rotating bodies 75L and 75R) is provided in the vicinity of the opening 73d of the inclined field 73. For this reason, at the time of the lottery game, when the ball b3 that has fallen to the high level (back) on the inclined surface 73a through the rail 72 rolls toward the lower side toward the opening 73d, the rotating bodies 75L and 75R move toward the high level of the inclined surface 73a. It is rebounded and makes an irregular movement on the tilt field 73. Then, the residence time of the ball b3 in the inclined field 73 is not constant, and the timing at which the ball b3 passes through the opening 73d also varies. Accordingly, the player cannot easily predict whether or not the ball b3 enters the focused pocket 74a (for example, the SJP winning pocket 74a) for the plurality of pockets 74a that move relative to the opening 73d. Therefore, according to such a configuration, the player can enjoy the lottery game by moving the ball b3 while maintaining the degree of expectation and excitement, and can enhance the interest as a lottery device. In some cases, the ball b3 dropped on the inclined surface 73a through the rail 72 may pass through the opening 73d without being rebounded by the rotating bodies 75L and 75R.

  In the present embodiment, as described above, the rotational speeds of the left and right rotating bodies 75L and 75R are different from each other. As a result, the ball b3 repelled by the rotating bodies 75L and 75R moves more irregularly in the inclined field 73 than when the rotating bodies 75L and 75R are rotated at the same speed. Therefore, according to such a configuration, the degree of expectation and excitement of the player can be further increased, and the interest as a lottery apparatus can be further increased.

  When the rotating bodies 75L and 75R are rotated at the above rotational speed, the residence time of the ball b3 in the inclined field 73 is measured several hundred times. The residence time is distributed in the range of about 4 seconds to about 120 seconds. It was. That is, the ball b3 falling on the inclined surface 73a may pass through the opening 73d quickly without being rebounded by the rotating bodies 75L and 75R, or may be rebounded many times by the rotating bodies 75L and 75R. In some cases, it does not pass through 73d. On the other hand, the rotation speed of the winning table 74 is, for example, about 13 seconds / rotation. For this reason, even if the SJP winning pocket 74a passes just below the opening 73d when the ball b3 is in the inclined field 73, the winning table 74 is opened once more or two more times and the SJP winning pocket is opened 73d. There is a possibility that the ball b <b> 3 stays in the inclined field 73 until it passes just below the angle. Therefore, according to the present embodiment, there is a possibility that SJP winning chances will be repeated, and from this point of view, the player's expectation level and excitement level are further increased.

  In the inclined field 73, the bounce portion 73c that regulates the movement area of the ball b3 includes a rubber ring that can play the ball b3. For this reason, the ball b <b> 3 that rolls in the inclined field 73 also moves irregularly when it is bounced by the bound portion 73 c. Such a configuration is suitable for producing an irregular movement of the ball b3 that is difficult to predict.

  Each of the rotating bodies 75L and 75R includes an elastically deformable upright blade plate 75b that protrudes outward in the radial direction of the rotation shaft s2 from the support member 75a. As a result, the ball b3 hits the blade 75b and is bounced, and the ball b3 can be rebounded efficiently with an appropriate elasticity. Further, even when the ball b3 is repeatedly bounced by the rotating body 75 (blade plate 75b), it is possible to prevent the disadvantage that the ball b3 is damaged.

  Further, since the blade plate 75b can be elastically deformed, the gap size g2 when the blade plates 75b are closest to each other is determined from the diameter d1 of the ball b3 so that the ball b3 can be easily repelled by the rotating bodies 75L and 75R. However, the problem that the ball b3 is sandwiched between the blades 75b and cannot be rotated is prevented.

  Although the embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above-described embodiment. Various changes can be made to the specific configuration of each part of the lottery apparatus according to the present invention without departing from the spirit of the invention.

  The rotating body for repelling the lottery medium (ball b3) may be configured such that the rotation speed can be changed. In this case, if two inverter motors are used as motors for rotationally driving the pair of left and right rotating bodies, the rotational speeds of the pair of rotating bodies can be independently changed. In this case, the rotational speed of the rotating body can be determined by screen lottery performed using the image display device 2, for example. Moreover, it is good also as a structure which can change a rotational speed only to one side of a pair of rotary body. In that case, two inverter motors may be used as motors for rotationally driving the pair of left and right rotating bodies, or only one of them may be an inverter motor. Furthermore, at least one of the pair of rotating bodies may be in a stopped state (rotational speed is 0).

  If the rotation speed of the rotating body is changed, the frequency with which the lottery medium is rebounded by the rotating body can be changed. That is, when the rotating body is rotated at a high speed, the lottery medium is easily rebounded, and the residence time of the lottery medium in the inclined field tends to be relatively long. On the other hand, when the rotating body is rotated at a low speed, the lottery medium is hardly rebounded, and the residence time of the lottery medium in the inclined field tends to be relatively short. Therefore, when the rotational speed of the rotating body is variable, the timing at which the lottery medium passes through the opening can be roughly changed.

  The lottery apparatus according to the present invention may be configured to perform two or more types of lottery in which the content of the prize in the winning opening (pocket 74a) is changed. For example, in the center lottery apparatus 7 of the above embodiment, when the SJP lottery is performed, if the SJP winning or the predetermined number of medal payouts is won, the process proceeds to a so-called double-up lottery game for doubling the medal payout number. You may comprise so that it can do. In this case, at the time of double-up lottery, the contents of the prize are internally changed so that only 10 pockets 74a other than the missed arrangements are simply “win (× 2)”. FIG. 11 shows an arrangement of award winning prizes in a double-up lottery, where “winning (× 2)” and “out of place” winning prize openings are alternately arranged. At the time of a double-up lottery, an alternative lottery that determines either “win (× 2)” or “out of place” is performed. If the winning holes of “winning” and “off” are alternately arranged, the winning is made with an average probability of about ½ regardless of the length of the dwelling medium residence time in the inclined field. If the result of the double-up lottery is “out of place”, the number of medals paid out in the SJP lottery is confiscated (0 times).

  When the double up lottery is additionally employed, the rotational speed of the rotating body may be changed. For example, the rotational speed of the rotating body is relatively high during the SJP lottery, and the rotational speed of the rotating body is relatively low during the double-up lottery. In this case, at the time of SJP lottery, the residence time of the lottery medium in the inclined field can be relatively long, so there is a possibility that the chances of winning SJP will come repeatedly. On the other hand, in the double-up lottery, since the residence time of the lottery medium in the inclined field can be relatively short, the two-choice ("winning", "out of") lottery can be performed so that the player does not get bored Finish relatively quickly. Therefore, according to such a configuration, compared to the SJP lottery, it is possible to advance the game with a high tempo in the lottery in which it is not necessary to lengthen the residence time of the lottery medium in the inclined field. It is possible to effectively produce lottery games with different numbers.

  In addition, when configured to perform two or more types of lottery in which the contents of the prize at the winning opening are changed, for example, in the center lottery device 7 of the above embodiment, instead of the above-described double-up lottery, Alternatively, a lottery that is not dependent on the SJP lottery (hereinafter referred to as a normal lottery in order to be distinguished from the SJP lottery) may be performed. As the winning lot in the normal lottery, a configuration in which “winning” and “off” winning slots are alternately arranged can be adopted as in the case of the double-up lottery described above with reference to FIG. The normal lottery is executed, for example, when a predetermined result is obtained in an electronic game (screen lottery) executed on an image display device or the like. Configured. In this case, for example, if the rotation speed of the rotating bodies 75L and 75R in the normal lottery is set lower than that of the rotating bodies 75L and 75R in the SJP lottery, the residence time of the lottery medium in the inclined field is relatively short. Can be. Therefore, the alternative lottery can be completed relatively quickly so that the player does not get bored, as in the case of the double-up lottery.

  In the above-described embodiment, an example is shown in which one winning slot is assigned to 20 winning slots (pocket 74a) as an SJP lottery in the SJP lottery. However, the total number of winning slots is not limited to twenty. In addition, a plurality of winning mouths may be assigned for SJP winning. Furthermore, the lottery game performed using the lottery device may be a lottery game that can obtain a special winning result, and is not limited to the SJP lottery.

  In the above-described embodiment, the configuration example including the two motors 75c that respectively rotate the rotating bodies 75L and 75R has been described. However, for example, the two rotating bodies 75L and 75R are interposed by one motor with a gear mechanism and a belt mechanism interposed therebetween. It is good also as a structure which rotates. In this case, if an inverter motor is used, the two rotating bodies can be tuned to be variable in speed.

  The pair of rotating bodies 75L and 75R may have the same speed. Further, at that time, it is desirable to shift the rotation phases of the rotating bodies from each other to give a long residence time.

  In the rotors 75L and 75R of the above embodiment, the blade plates 75b (lottery medium repelling members) are arranged in parallel, but instead, for example, the blade plates may be crossed in a cross shape. Good. Further, the shape of the lottery medium repelling member is not limited to a flat plate shape, and may be, for example, a sphere, an ellipse, or a polyhedron. The lottery medium repelling member may be made of a rigid plastic member. Further, instead of the rotating body, a rocking body that rocks within a predetermined rotation angle range may be provided, and the lottery medium may be rebounded by the rocking body.

  Furthermore, the number of rotating bodies is not limited to two, and may be one or three or more. Moreover, the rotary body should just be arrange | positioned so that the lottery medium which moves toward an opening can be repelled.

  The inclined surface 73a may be a shape that allows the lottery medium (ball b3) to move toward the opening, may be a curved surface, and has irregularities that cause the lottery medium (ball b3) to move more irregularly. There may be obstacles such as.

  The elastic body of the bound portion 73c is not limited to a rubber ring, and may be a coil spring, a leaf spring, or the like. Further, the rear wall 73b may be made of an elastic body, like the bound portion 73c. However, the bounce part 73c and the back wall 73b do not necessarily need to be elastic bodies, and may be any configuration that restricts the movement of the lottery medium (ball b3) (for example, a hard plastic member such as metal).

  In the above-described embodiment, it is configured to have a plurality of winning ports (pockets 74a), but may be configured to have only one winning port. Further, as a configuration in which the winning opening is periodically moved relative to the opening, for example, instead of a configuration that moves along the circumference as in the above-described embodiment, for example, the winning opening is periodically moved to the left and right along a straight line or a curve. It is good also as a structure which reciprocates. Furthermore, the winning opening is not limited to one that periodically moves with respect to the opening, and one winning opening may be a winning opening that electronically (internally) switches between winning and non-winning states. The open / close device provided at the mouth may be used to switch between a winning and a non-winning state (for example, if the ball falls while the winning opening is closed, the ball is collected without entering the winning opening and is “disconnected”. Becomes).

  The lottery medium is not limited to a spherical ball, but may be a rolling element having another shape that can move by rolling on an inclined field such as a polygon. Further, it may be one that slides on an inclined field such as medals and coins.

  The lottery device according to the present invention is not limited to a medal game machine, and can be installed in various other game machines. Furthermore, a game machine may be configured by a lottery device alone.
