The light is converted to pass through the vertical passage formed between the partition walls 68 and 71 and the throat formed by the side wall portions 52 and 53 of the second optical sensor 50, and flows downward.

Further, the ball on the inclined portion 43 on the other side, that is, the general winning ball, passes through the opening 65 as shown in the arrow C in FIG.
It enters the space portion, passes through the downward passage formed by the partition wall 69, and the throat formed by the side wall portions 52, 53 of the third optical sensor 50, and flows downward.

Each optical sensor 50 generates a winning ball detection signal each time the winning ball passes through the throat formed by the side walls 52 and 53.

When a prize is entered into the introduction port 36 as a continuous winning opening in the center, it is detected as a specific winning ball and the continuation display portion (not shown) is lit, and the continuation condition of the special prize mode is satisfied, for example, at the present time. It is visually displayed to the player that the opening / closing door 33 is opened again for a predetermined time even after the continuing opening operation for about 30 seconds.

When a predetermined 30 seconds elapses or when the total number of winning balls detected and counted by each optical sensor 50 reaches a specified number, the electromagnetic solenoid 77 is deenergized and the opening / closing door 33 is closed.

After that, this operation is repeated, and the opening / closing door 33 is opened 10 times in total, and the operation is finished.

The variable winning apparatus shown in FIGS. 13 to 16 is a first winning space portion which is a winning area where a hit ball easily wins an opening by the opening / closing door when the opening / closing door is opened forward in front of a mounting board. And a second space portion provided with a distribution mechanism that divides a hit ball that has won a prize from the opening on the back surface side of the mounting substrate into a specific winning ball and a general winning ball, and a specific winning ball that is divided in the second space portion. An optical sensor according to the present invention is removably engaged with each ball passage of the third space part through which the general and special prize balls pass, the third space part being configured to be able to flow down. When the opening / closing door is opened and the first prize space portion appears, even if a large number of hit balls are won in a short time, the distribution mechanism separates the specific prize ball from the general prize ball. Can be divided surely, and the winning hit ball can be quickly processed in the second space part and is blocked. Not only can the ball stopper be lost, but even if the U-shaped optical sensor breaks down, it can be replaced very easily and quickly at a game shop.

Therefore, not only does the player have to change the pachinko machine or keep it for a long time during the repair, but also the unusable machine due to the failure of the optical sensor can be eliminated, and the management efficiency is improved. Can be measured.

(Effects of the Invention) As described above, the present invention performs the processing for accepting a winning hit ball in three steps.
Since the mechanism that allows the flow-down process to be performed stepwise by the overlapping space portion, when the variable winning device is opened and the changing member is converted into the first state advantageous to the player, and the first winning space portion appears, Even if a large number of winning balls are won in a short time, the winning balls can be sequentially rectified and guided in one row in the second space portion, so that one winning ball can be surely detected sequentially.

In addition, the large number of winning hit balls generated in the second space portion can be quickly processed, and there is no possibility of being blocked or stopping the ball in the second space portion.

Furthermore, this optical sensor is integrally molded in a U-shape, and its base can be detachably inserted into an appropriate engagement so that it can be mounted. It can be attached and removed relatively easily even by an amateur, without the trouble of.

In particular, even if the U-shaped optical sensor breaks down, it can be replaced very easily and quickly at the game store, so the player has to change the pachinko machine or wait a long time during repair. Not only can it not be used, but it can also eliminate the unusable stand due to the failure of the optical sensor,
You can measure the efficiency of management.
