  As is well known, pachinko machine games are directed to the game area by the player turning the launch lever that is pivotally attached to the operation handle protruding from the pachinko machine. This is done by launching a game ball. In this way, the game balls launched toward the game area flow down the game area while hitting a large number of game nails and various structures driven into the game area. As a result, the game ball flowing down the game area changes its flow direction every time it hits a game nail or various structures, and as a result, it is difficult for the player to predict the flow direction of the game ball. It has become. Then, by making it difficult to predict the flow direction of the game ball in this way, the player is relieved about the behavior of the game ball. Therefore, making it difficult to predict the flow direction of the game ball is one factor for entertaining the player.

  By the way, a pachinko machine is generally provided with a center accessory that characterizes the pachinko machine itself in the approximate center of the game area. Specifically, for example, a center ornament arranged around the display screen of the liquid crystal display in the first type pachinko machine is the same.

  A stage for rolling the game ball is formed in such a center character, and the game ball guided on the stage through a guide passage formed in the center character is on the stage. Can be rolled.

Therefore, the stage formed on the center role is positioned above the position where the start winning device is arranged in the stage in order to facilitate the winning of the game ball that can roll on the stage to the start winning device. In many cases, an inclined surface is formed in the portion to be formed. Therefore, the player is very interested in the whereabouts (rolling direction) of the game ball that can be rolled on the stage formed in the center role.

  Further, in recent pachinko machines, for example, in the case of the first type pachinko machine, due to the tendency to adopt a large liquid crystal display, the center accessory itself becomes larger, The ratio of the center role in the game area is increasing, and as a result, the game area is becoming narrower. Therefore, the existence of the stage formed in the center role has become very important, and it is no exaggeration to say that such a stage constitutes a part of the game area.

  In view of this, a pachinko machine has been proposed in which a stage having an inclined surface is formed in the center accessory and a plurality of obstacle protrusions are provided on the stage (see Patent Document 1).

  However, in the pachinko machine as described above, the rolling direction of the game ball that is allowed to roll on the stage can be changed due to contact with the obstacle projection of the game ball. The principle of changing the rolling direction of the rolling game ball and the principle of changing the flowing direction of the gaming ball flowing down the game area are the same, and even if the rolling direction of the folding game ball is changed, it is interesting There is a problem of lacking.

  In order to cope with such a problem, Patent Document 2 discloses that when a rotating drum is disposed on a stage formed in a center accessory so as to be rotatable about one axis, and the rotating drum is rotated. Further, there is disclosed a pachinko machine in which a game ball is attracted to a magnet assembled in a rotary drum and the game ball may be induced by rotation of the rotary drum. The movement itself becomes monotonous, and the player may get bored with the movement.

The angular velocities of the rear-side rotating drum 80b are different. In particular, in the present embodiment, the gear ratio of the right front drive gear 110b and the right rear drive gear 112b is 3: 5, and thereby the angular velocity of the right front rotation drum 76b is set. This is faster than the angular velocity of the right-side rear rotating drum 80b. In the present embodiment, the left front drive gear 110a and the left rear drive gear 112b have different gear ratios, whereby the angular velocity of the left front rotation drum 76a and the left The angular velocities of the back-side rotating drum 80a are different. In particular, in the present embodiment, the gear ratio between the left front drive gear 110a and the left back drive gear 112a is 3: 5, and thus the angular velocity of the left front rotation drum 76a is set. This is faster than the angular velocity of the left-side inner rotary drum 80a. As is clear from this, in this embodiment, the angular velocities of the two front rotating drums 76a and 76b are the same, and the angular velocities of the two rear rotating drums 80a and 80b are also the same. Yes.

  The right front side and back side drive gears 110b, 112b for rotating the right front side and back side rotating drums 76b, 80b in this way, and the right front side and back side drive gears 110b, The right relay gear 114b meshed with both 112b is housed in a housing space (not shown) formed in the right wall 96 of the right housing hole 70b and driven.
