  2 and 3, the lottery device 7 includes a lottery board 70 having one recovery hole 70A for collecting the ball B as the ball B rolls, and the lottery board 70 includes the ball B A ball throwing means comprising a spring 71A and a guide rail 71B for throwing the ball, a rotating plate that rotates around the vertical axis on the lottery board 70 and has a plurality of recesses 72A that can receive and hold the ball B from the side. 72, a collection box 73 for holding the collected ball B, a plurality of light emitters (winning hole notifying means) 74 for notifying the concave portion to be a winning hole by light, and a microcomputer for controlling the lottery game It has the control part 75 which consists of these.

  In the lottery board 70, the surface of the ball B on which the ball B rolls is formed in a transparent and concave shape, and the inserted ball B gradually rolls toward the center. The recovery hole 70A is formed between the center portion and the outer peripheral portion of the lottery board 70.

  The ball throwing means compresses the spring 71A provided below the lottery board 70 with the first and second rotating pins 71C and 71D, and then pushes up the push rod 71E by releasing the compressed state, thereby guiding the guide rail. The ball B is thrown on 71B. The guide rail 71 </ b> B extends from the lower side to the upper side of the lottery board 70 and is provided so as to make one round of the outer periphery of the lottery board 70. The ball B moves while rolling on the guide rail 71 </ b> B, and finally falls into the lottery board 70.

  The rotating plate 72 is maintained at the middle height of the ball B on the lottery board 70, and is rotated by the rotating motor 72B. As well shown in FIG. 4, the recesses 72 </ b> A of the rotating plate 72 are provided at equal intervals with marks 1 to 6 as an example, and the balls B heading toward the center of the lottery board 70. Fits into one of the recesses 72A. The recovery hole 70 </ b> A is provided on a circular path C in which the concave portions 72 </ b> A move as the rotating plate 72 rotates. The ball B held in the recess 72A falls into the recovery hole 70A when the recess 72A is at the same location as the recovery hole 70A.

  As well shown in FIGS. 4 and 5, the first rotor 76 </ b> A, the second rotor 76 </ b> A, and the second rotor 76 </ b> A are provided on the shaft of the rotating plate 72 and the periphery thereof as rotational position detecting means for detecting the rotational position of each recess 72 </ b> A. A rotor 77A, a first sensor 76B, and a second sensor 77B are provided. The first rotor 76 </ b> A has a plurality of protrusions as detection portions corresponding to the respective recesses 72 </ b> A at intervals of approximately 60 degrees, and rotates integrally with the shaft of the rotating plate 72. The second rotor 77A has one protrusion as a detection portion corresponding only to the reference recess 72A, for example, which is a reference, and the shaft of the rotary plate 72 at a height position different from that of the first rotor 76A. And rotate together. The first and second sensors 76B and 77B are made of, for example, a photo interrupter, and are installed so as to detect the protruding portions of the first and second rotors 76A and 77A, respectively. Further, on both lower sides of the recovery hole 70A, a ball drop detection sensor 78 made of, for example, a photo interrupter and detecting that the ball B has dropped is provided.

  For example, as shown in FIG. 4, in a state in which the number 1 recess 72A coincides with the recovery hole 70A, the protruding portion of the first rotor 76A is detected by the first sensor 76B and the second rotor 77A. Is detected by the second sensor 77B. That is, the control unit 75 recognizes that the concave portion 72A of number 1 coincides with the recovery hole 70A based on the detection signals from the first and second sensors 76B and 77B. Thereafter, each time the rotating plate 72 rotates approximately 60 degrees clockwise, the protruding portion of the first rotor 76A is detected by the first sensor 76B. Thereby, the control part 75 recognizes that the recessed part 72A of the numbers 2-6 is in the state which corresponded in order with the collection | recovery hole 70A. When the rotating plate 72 is further rotated and the protruding portion of the second rotor 77A is detected again by the second sensor 77B, the concave portion 72A of No. 1 coincides with the recovery hole 70A. In this manner, the control unit 75 grasps the rotational positions of all the recesses 72A and can specify the recesses 72A located at the same location as the recovery holes 70A. When the control unit 75 receives a signal indicating that the ball B has dropped into the recovery hole 70A from the ball drop detection sensor 78, the control unit 75 stops the rotation of the rotating plate 72. At this time, if the control part 75 specifies, for example, the concave part 72A of number 1 as the concave part at the same position as the recovery hole 70A, it is determined that the ball B is held in the concave part 72A of number 1.

  As shown in FIG. 2, the plurality of light emitters 74 are made of color LEDs, for example, and are arranged on the back side of the lottery board 70. These light emitters 74 are fixed at positions corresponding to the respective recesses 72A when the rotating plate 72 is stopped from rotating, and light is emitted from which of these recesses 72A is a winning hole. Inform the player.

  The control unit 75 starts the lottery game when the three numbers displayed on the display unit 8 are aligned, and determines which of the plurality of recesses 72A is to be a winning hole based on a predetermined program. The number of winning holes varies depending on the size of the numbers that are aligned, and may be only one or may be two or more. That is, the probability of winning varies, and the winning hole can be any of the recesses 72A numbered 1-6. For example, if the recesses 72A of No. 1 and No. 3 are determined as winning holes, the control unit 75 causes the light emitters 74 at positions corresponding to the recesses 72A of No. 1 and No. 3 in a state where the rotation plate 72 is stopped. Lights up.

  Next, the operation of the lottery device 7 will be described.

  For example, when the lottery game is started with the number 72 concave portion 72A as a winning hole, one ball B is inserted into the lottery board 70, and after a while, the ball B is placed in any one of the concave portions 72A in the rotating rotating plate 72. Retained. Note that two or more balls may be thrown into the lottery board 70. In such a case, the probability of winning can be increased.

  The rotating plate 72 is rotated while holding the ball B in the recess 72A. When the recess 72A holding the ball B comes to the position of the recovery hole 70A, the recovery hole 70A where the ball B is directly below the recess 72A. Fall into. When the fall of the ball B is detected by the ball fall detection sensor 78, the rotating plate 72 stops rotating.

At this time, the control unit 75 specifies the number of the recess 72A at the same position as the recovery hole 70A based on the detection signals from the first and second sensors 76B and 77B. For example, when the concave portion 72A located at the same position as the recovery hole 70A is identified as number 1, since the concave portion 72A is a winning hole and the ball B has entered, the control unit 75 determines that the winning state has been won. When winning, the control unit 75 tilts the bucket 9 in which a large number of prizes are placed. As a result, the prize placed in the bucket 9 falls to the prize drop port 5 and the pusher table 61, and a large number of prizes are paid out. On the other hand, when the recesses 72A located at the same position as the recovery hole 70A are numbers 2 to 6 that become the breakout holes, the control unit 75 determines that they are in a slipping state and ends the lottery game. In such a lottery game, the probability that the ball B enters in any of the recesses 72A is equal, and the probability of winning increases as the number of winning holes increases, so the player is expected to increase the possibility of winning. However, you can enjoy the lottery game.

  Therefore, according to the lottery device 7 of the present embodiment, when it is detected that the ball B has fallen into the recovery hole 70A, the concave portion 72A located at the same position as the recovery hole 70A is recognized as a place where the ball B enters. Therefore, it is possible to specify the concave portion 72A containing the ball B with a simple mechanism for all the concave portions 72A, and easily change the probability of winning by changing the number of winning holes. be able to.

  In addition, this invention is not limited to said embodiment. For example, the lottery device can be used not only for a prize acquisition game machine but also for a medal game machine, and various design changes can be made without departing from the spirit of the present application.
