The foul ball collected by the foul ball collection chute 12 also joins the guiding gutter 57 and is discharged from the outlet 58 to the plate portion 52 of the lower ball receiving tray 7.

The operation of the pachinko machine having the above configuration will be described. As shown in FIG. 5 and FIG. 9, the pachinko balls stored in the upper ball tray 6 are continuously arranged in a line by the rectifying unit 18, continuously from the ball outlet 19 of the front plate 5 through the inflow port 25 to the supply passage 26. The pachinko ball B positioned at the head thereof is received by the circular arc surface on the upper surface of the ball support portion 32 of the ball feeding member 23 placed in a state of being rotated downward, and waits. At this time, the pachinko ball B on the ball support portion 32 is supported by the inclined surface of the ball support portion 32 so as to be able to roll into the ball extraction port 27 as shown in FIG. Outflow from the ball outlet 27 is prevented. Therefore, in this state, even if an excessive ball pressure of the pachinko balls stored in the upper ball receiving tray 6 is applied to the ball removing member 38, the ball removing member 38 moves in the ball removing direction and the ball removing port 27 is closed. Without being opened, the ball extraction port 27 is reliably kept closed.

On the other hand, in this state, the player operates the operating handle 8.
When the hammer 11 is rotated to the firing preparation position as shown by the chain line in FIG.
, The plunger 35 of the solenoid 24 contracts upward against the bias of the compression coil spring 59, and rotates the ball feed member 23 upward. As a result, the pachinko ball B received by the ball support portion 32 falls and is held by the ball receiving concave portion 33 as shown by the chain line in FIG.

Next, the hammer 11 rotates from this state,
When the firing operation is started, the power supply to the solenoid 24 is cut off, and the plunger 35 of the solenoid 24 projects downward by the urging of the compression coil spring 59, and the ball feed member 23
Is rotated downward. Then, the sling of the ball receiving concave portion 33 supplies the pachinko ball B from the supply port 29 to the firing position 10 of the firing rail 9. At the same time, the succeeding pachinko ball B1 is supported by the upper surface of the arc of the ball support portion 32. Thereafter, the solenoid 24 is synchronized with the reciprocating rotation of the hitting hammer 11.
Each time the demagnetization is performed, one pachinko ball in the upper ball receiving tray 6 is reliably supplied to the firing position 10 of the firing rail 9 one by one.

In order to extract the pachinko balls of the plate portion 15 of the upper ball receiving tray 6 into the lower ball receiving tray 7, the operating member 47 is pressed as shown by a chain line in FIG. Rotate against. As a result, the ball removing member 38 moves in the direction of the arrow in the figure via the projection 44 engaging with the long hole 45 of the lever member 41, and opens the ball removing port 27 as shown in FIG.

For this reason, the first pachinko ball B received on the upper surface of the arc of the ball support portion 32 of the ball feed member 23 and waiting in the supply passage 26 loses the support by the ball punching member 38, and the ball is inclined by the inclined surface. The guide ribs roll from the extraction port 27 to the upper passage portion 51 a of the ball ejection passage 51, and the pachinko balls of the succeeding upper ball receiving tray 6 also drop onto the ball support portion 32 of the ball feed member 23 through the supply passage 26. 30, the ball is continuously rolled from the ball extraction port 27 to the upper passage portion 51a of the ball ejection passage 51 by the inclined end wall 28, and all the pachinko balls are passed through the lower passage portion 51b. Of the tray 52.

After the pachinko ball of the upper ball receiving tray 6 is extracted into the lower ball receiving tray 7 and the pressing of the operating member 47 is released, the return force of the coil spring 46 causes the link member 4 to return.
8 returns to the original position shown by the solid line in FIG. 8, and at the same time, the ball removing member 38 moves to the position shown in FIG. 9 to close the ball removing port 27.

It should be noted that the ball passage 51 is provided with a vertical passage 51.
a, 51b is not limited to the one divided into two parts, and even if it is further divided into a plurality of parts, if the diameter of the inlet of the passage part located below the outlet of the passage part located at the top is made large, Good. Also, instead of having a straight shape having a different diameter as shown in the figure, a funnel shape may be formed.

Further, in the above embodiment, the configuration has been described in which the ball is removed through the hitting ball supply device 21.
A configuration may also be adopted in which a ball hole is provided at the downstream end of the straightening portion 18 of the upper ball receiving tray 6 and the ball hole is closed by a ball hole member. Furthermore, although the ball passage has been described as a ball passage,
The present invention is not limited to the ball passage, and is applicable to any ball passage that connects the upper ball tray and the lower ball tray on the front side of the front frame.

[0029]

As described above, in the pachinko machine according to the present invention, the connecting portion of the ball passage connecting the upper ball tray and the lower ball tray on the front side of the front frame is located below the outlet of the upper passage portion. By making the inlet of the passage portion a large diameter, it is possible to eliminate ball clogging due to rattling or displacement and to reliably flow down the ball passage. In particular, the effect is remarkable for a ball passage provided on the open side.
