And Japanese Patent Application Laid-Open No. 6-254223. The variable winning device described in the former publication is provided with a ball receiving member for rolling a winning ball so as to perform a seesaw motion about a longitudinally central bearing by a solenoid, and when the solenoid is not driven, The ball receiving member is forcibly held in a posture tilted toward the normal winning opening by a resilient pressure of a compression spring mounted on a plunger of a solenoid. The variable prize winning device described in the latter gazette has a fixed guiding flow path for guiding a winning ball to a specific winning port and a normal winning port arranged adjacent to each other, and a special winning port for guiding the winning ball to a normal winning port. The structure is provided with opening / closing means for appropriately preventing the ball from entering.

[0003]

In the former variable prize winning apparatus, when a plurality of prize balls are successively loaded on a ball receiving member inclined to the normal prize port side, the weight of the balls is reduced. Since the ball receiving member is tilted to the opposite side by overcoming the elastic pressure of the spring, there is a concern that the winning ball may be guided to the specific winning opening side. Further, the ball receiving member for performing the seesaw movement becomes large and the driving mechanism portion becomes large, so that it occupies a large space for installation on the game board, which is a factor that restricts the gauge configuration of the game board. In the latter variable winning device, since the winning ball entering the big winning opening always shows a monotonous operation of moving in the guiding flow path in a certain direction, there is a possibility that the player lacks interest.

Next, the operation of the variable winning device A having such a configuration will be described in relation to other characters. During a pachinko game, when a hit ball enters any of the winning slots (not shown), a variable display section (not shown) operates to continuously display an arbitrary number or pattern. When the display portion of the variable display section is aligned with a specific series of numbers or patterns, a special game state called "big hit" is entered, and the solenoid 7 is driven to open the open / close plate 3 as shown in FIG. 2 is released. When the hit ball enters the winning opening, the solenoid 30 is driven and the exit direction of the concave groove 27 of the rotary guide 25 is switched to correspond to the specific winning opening 41 side before opening the opening / closing plate 3. Can be

The hit ball rides on the opening / closing plate 3 and enters the special winning opening 2 to become a winning ball x. The winning ball x passes through the guiding room 11 (FIG. 3) and enters the specific winning opening 41. The first winning ball x (hit ball) is detected by the first detection switch 40, and the solenoid 30 is not driven by the detection signal, so that the rotary derivative 25 rotates clockwise and the exit direction of the concave groove 27 changes. It is switched to correspond to the normal winning opening 43 side. Note that the first winning ball x does not enter the specific winning opening 41 but directly enters the normal winning opening 43, and the second and subsequent winning balls x are within a certain number (for example, 10) or for a certain time (for example, 20 seconds)
If the player enters the special winning opening 41, the special game can be continued. If no hit ball enters the specific winning opening 41 within the above conditions, the special game state ends (a so-called puncture state).

The second and subsequent winning balls x roll rightward along the exit direction of the groove 27 of the rotating guide 25 (FIG. 6),
It enters the normal winning opening 43 and is counted by the second detection switch 42. Thus, when the number of winning balls entering the normal winning opening 43 becomes nine, or the total number of winning balls entering the specific winning opening 41 and the ordinary winning opening 43 becomes ten, the solenoid 7 is not driven, and The opening / closing plate 3 is closed.

This sequence of operations is repeated up to 16 times according to current standards in the industry. If there is a revision of the current standard, the number of revisions is not limited to this. When the winning operation to the specific winning opening 41 has been completed 16 times, the open / close plate 3 is closed by the solenoid 7 and the special game state ends.

In the variable winning device of the pachinko machine, a series of mechanisms for guiding a winning ball to a specific winning opening or a normal winning opening can be simplified and reduced in size, and cost can be reduced.
