A safe ball P ₂ from (not shown) is rolled guided. 2
Reference numeral 5 denotes a feed wheel supported by a shaft 26 within the operating box portion 23, and has four recesses on its outer periphery for receiving the safe balls _P2 from the gutter 27 which is continuous with the safe ball passage 24. 25a is formed. The feed wheel 25 is always rotated in the direction of the arrow by a motor (not shown) when the pachinko machine is in operation, but may be rotated only when the safe ball P ₂ passes through the safe ball passage 24. 28 is a shaft 29 above the feed wheel 25.
The operating lever is swingably supported by the lever, and an engaging portion 28a is formed at the lower edge thereof. As the feed wheel 25 rotates, the safe ball P ₂ in the recess 25a engages with the engaging portion 28a and the operating lever 28 is rotated upward, thereby causing the operating lever 28 to pivot. Supported operating rod 30
moves upward to operate the prize ball ejection case 21 for ejection.

Reference numeral 31 denotes a recovery passageway connected to the lower part of the operating box section 23, which guides the safe balls _P2 that have fallen from the rear feeder wheel 25 engaged with the operating lever 28 to the safe ball recovery device.

Reference numeral 38 denotes an interlocking lever arranged between the detection member 32 and the rotating lever 34, and rotatably supported by a shaft 39 at the intermediate portion, with both ends connected to the detection member 32 via connecting links 40 and 41, respectively. is connected to the lower end of the detection member 32 and the other end of the rotating lever 34, so that rotation of the detection member 32 in the direction of the arrow is transmitted to the rotating lever 34 as rotation in the safe ball blocking direction.

Reference numeral 42 denotes a release member disposed between the interlocking lever 38 and the set arm 4, and rotatably supported by a shaft 43 at the upper end, when the detection member 32 is rotated in the direction of the arrow as shown in FIG. Engagement portion 38a formed on interlocking lever 38 when moved
It is adapted to be engaged with and rotated in the direction of the arrow. By this rotation, the release member 42 engages with the pin 4c formed on the lower protrusion 4b of the set arm 4, and releases the engagement between the set arm 4 and the operating rod 3 of the ball hitting rod 1, thereby releasing the ball. Even when the rod 1 rotates in the direction of preparing to hit a ball, it does not act on the set arm 4. Therefore, by the rotation of the release member 42, the ball delivery member 11 is rotated to the ball holding position via the set arm 4, and balls are not supplied to the ball delivery rail 2.

Now, when the pachinko machine is operated, the safe ball P ₂ passes through the safe ball passage 24 and reaches the operating box part 23.
Once inside, the safe ball _P2 is received by the recess 25a of the constantly rotating feed wheel 25, rotates upward, and engages with the engaging portion 28a of the operating lever 28. Therefore, the operating rod 30 moves upward and the prize ball discharge case 21 is operated, and a certain number of prize balls _P1 are discharged, and the prize balls _P1 pass through the main part 22a of the prize ball gutter 22 and enter the upper tray. Supplied. Note that the engaging portion 28a
The set ball P2 that has been engaged with the ball _P2 reaches the recovery device through the recovery passage 31.

When the upper tray and main portion 22a are filled with prize balls _P1 , subsequent prize balls _P1 are supplied to the lower tray through the branch portion 22b. Furthermore, as shown in FIG. 4, when the prize balls P ₁ in the lower saucer are filled and the prize balls P ₁ stay in the branching part 22a, the remaining prize balls
The detection member 32 is rotated in the direction of the arrow by P ₁ , the rotation lever 34 is also rotated in the direction of the arrow, the blocking member 37 protrudes from the through hole 36 into the safe ball passage 24, and the safe ball P ₂ is sent. Prevent it from moving to the car 25 side. Therefore, after the blocking operation of the blocking member 37, the feed wheel 2 passes past the blocking member 37 before the blocking operation.
Only the safe ball _P2 flowing to the 5th side is sent to the feeder wheel 25 and operates the prize ball ejection case 21, whereby the ejected prize ball _P1 is stored and accumulated in the remaining space of the branching part 22b. be done. In addition, when the safe balls P ₂ are fully lined up between the feed wheel 25 and the blocking member 37, the prize balls P ₁ are ejected from the prize ball ejection case 21 by all the safe balls P ₂ and the ball is ejected from the branching section 22.
b is almost full and can accommodate the prize ball _P1 to the maximum.

On the other hand, due to the rotation of the detection member 32, the set arm 4 is rotated in the direction of the arrow via the interlocking lever 38 and the release member 42, and the engagement of the ball batting rod 1 with the operating rod 3 is released. The feeding member 11 is rotated to the ball supply stop position, and the supply of pachinko balls P to the ball firing rail 2 is stopped. Therefore, even if the ball batting rod 1 performs a ball batting motion, the ball is not ejected, and the number of safe balls _P2 does not increase.

Therefore, if such a situation occurs, remove the prize ball _P1 in the lower saucer and replace the prize ball _P1 in the branch part 22b.
3, the detection member 32 returns to the position shown in FIG. 3 due to its own weight, the weight of the interlocking lever 38, etc., the blocking member 37 moves out of the safe ball passage 24, and the release member 42 also moves to the position shown in FIG. The set arm 4 returns to the position shown in FIG. 3 and engages with the operating rod 3. Therefore, the safe ball P ₂ in the safe ball passage 24 is supplied to the feeding wheel 25 and the ejection of the prize ball P ₁ is started, and the ball sending member 11 can swing in conjunction with the batting rod 1. Each time the ball batting rod 1 performs a ball hitting operation, a pachinko ball P is supplied to the ball firing rail 2 and the ball is fired.

As described above, the present invention includes a detection member in the prize ball gutter so as to detect when the prize ball gutter is filled with prize balls sent from the prize ball discharge case to the receiving tray through the prize ball gutter. movably arranged near the safe ball passage so that the safe ball guided from the safe ball passage to the actuating device for the prize ball ejection case is blocked in front of the actuating device by movement of the detection member. A blocking member is provided, and the ball sending device is stopped as the detecting member moves.
By linking the detection member and the batted ball feeding device, when a certain amount of prize balls stays in the prize ball gutter, it is possible to automatically stop the ejection of the prize balls and stop the batted balls at the same time. Since the prize ball discharging case does not eject prize balls in excess of the prize ball storage capacity of the prize ball gutter, an excellent effect is exhibited in that unexpected situations such as damage to the back mechanism can be reliably prevented.
