Description

[0001]
[Industrial application fields]
The present invention relates to a winning device for a pachinko machine that uses a rotating body to win winning balls at predetermined time intervals.
[0002]
[Prior art]
Conventionally, a winning device for a pachinko machine that uses a rotating body to win a winning ball at predetermined time intervals is known. As shown in FIG. 7, this winning apparatus has a rotating body 101 that is always rotated by a motor 100 and an annular guide frame 102 that surrounds the peripheral surface of the rotating body 101. A ball standby unit 103 is provided.
[0003]
When the ball holding portion 104 provided on the peripheral surface of the rotating body 101 coincides with the standby portion 103 of the guide frame 102, the game ball waiting on the standby portion 103 is taken into the ball holding portion 104 and a winning prize is received below. It is carried to the hole 105.
[0004]
On the other hand, this type of winning device is arranged on the game board in association with a starting winning port, a variable display, a large winning port called an attacker, etc., and when a game ball wins the starting winning port, When the display state changes and the display result of the stopped variable display is a win, a right is generated as a big win. When a game ball wins a winning device at the time of the occurrence of the right, the big win is fixed and the win is won. It is often used for a so-called right-type pachinko machine that opens a grand prize opening every time.
[0005]
[Problems to be solved by the invention]
By the way, the right type pachinko machine of the above-mentioned type is such that when the big hit right is generated, the big hit right is determined on the condition of winning the winning device, and the open / close cycle of the big prize opening is updated. If the gap between the nail of the obstacle nail arranged above the standby unit is widened so that the game ball can not easily enter the standby unit, even if the right to win a big break occurs, the right can be confirmed or a big prize If a player uses a large number of game balls to update the mouth opening / closing cycle, the game becomes less interesting, which may cause dissatisfaction with the player and cause separation of customers.
[0006]
On the other hand, if the nail interval of the obstacle nail is widened as described above to make it easier for the game ball to enter the standby section, the winning rate of the winning device increases, and the payout amount of the prize ball increases significantly even when rights are not generated. It was very difficult to adjust the distance between the nails, as the management of a pachinko parlor would not be possible.
[0007]
