DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine, and more particularly, to a special game state in which a special condition is satisfied and a special device is shifted from a first state disadvantageous to the player to a second state advantageous to the player. It relates to a pachinko machine that can be converted into a pachinko machine. As such a pachinko machine, for example, when a specific condition is established such that a hit ball wins a specific winning opening and the right state is established, the hit ball flows into the starting opening, and the game is played from the first state disadvantageous to the player. There is a so-called type 3 pachinko machine that can convert a special device that can be converted into the second state, which is advantageous to the user, into the second state.

[0002]

2. Description of the Related Art As is well known, many pachinko machines of this kind have been developed. For example, JP-A-2-172482
In the publication, a right generating device for creating a right state is configured with a prize device capable of expanding and reducing a prize area, and the prize device has a general prize port and a special prize port for generating a right. Have been.

[0003]

However, in the conventional pachinko machine, there is a margin of time from when the ball is entered into the prize-winning device to when the prize is entered into the general winning opening or the special winning opening. In some cases, the preceding ball may win the special winning opening, and the succeeding ball may also win the special winning opening depending on the timing. Therefore, even if the right is generated by the preceding ball, the right may be immediately extinguished by the subsequent ball. Therefore, the player fires aiming at the prize device which is a right generation device, and when the hit ball hits the prize device, activates the pause button until the ball is determined to stop firing the hit ball. The flight distance is adjusted so that the hit ball does not enter the winning prize tool by operating the steering wheel. For this reason, a useless ball is easily generated, and the willingness to play the game does not increase. In addition, since the operation of pachinko machines is temporarily suspended for pachinko parlors, the operation rate is reduced. On the other hand, according to the above-described pachinko machine, a player who is lucky or is good at game technology can acquire a large amount of prize balls. However, in a game store, if the game can be continued using the obtained prize balls, the sales will not increase. Therefore, depending on the game store, for example, when the above right is extinguished, the prize ball acquired during the right is exchanged for a prize, and when continuing the game further, it is requested to receive a new ball lending and obtained. Playing with prize balls is prohibited. However, if the game with prize balls is uniformly prohibited, players will be dissatisfied, so some players who have cleared the predetermined conditions will be offered a service that allows them to play with the prize balls are doing.
