A ball outlet 8 is formed on one side wall 7a of the box frame 7, and a ball outlet 8 is formed inside the box frame, and the box frame 7 is located slightly below the shafts 4, 4. A horizontal shaft 9 is provided, a weight 10 is installed in front of the horizontal shaft 9, and an operating member 12 whose front end is weighted by vertically disposing a ball receiving piece 11 is pivotally attached. When the movable pieces 3, 3 are in the upright position, the actuating member 12 intervenes with its heavy front end below the shafts 4, 4 to maintain the upright position as shown in FIG. It flips up to release the engagement with the movable pieces 3, 3, and performs a reciprocating motion in which it is tilted in an inverted figure-eight shape. Further, the actuating member 12 is provided with a holding means for holding the actuating member 12 in a position where the front end thereof is flipped up. This holding means is constituted by a magnet body 13 provided on the lower surface near the rear end of the actuating member 12 and a magnetic rod 14 installed below the box frame 7. and actuating member 1
The magnet body 13 is attracted to the magnetic rod 14 at the position where the front end of the magnetic rod 2 has sprung up, and is held in that position.

A batted ball winning device having the above-mentioned configuration is known as seen in Japanese Utility Model Publication No. 3020/1983 by the present applicant. In this batted ball winning device, when a batted ball enters between the upright movable pieces 3, 3, the ball flows backward from the ball inlet 2 on the upper surface of the actuating member 12, and the weight of the ball lowers the rear end as shown in FIG. A flip-up action is performed, and by this action, the movable pieces 3, 3 are released from engagement by the front end of the actuating member 12, and are tilted outward by the acting force of the weights 5, 5. When a ball hits between the tilted movable pieces 3, 3, the weight of the ball causes the movable pieces 3, 3 to stand up while the actuating member 1
The actuating member 12 is returned to the horizontal position shown in FIG. 3 by riding on the ball receiving piece 11 of No. 2, and the movable pieces 3, 3 are held in an upright state again by its front end.

As shown in FIGS. 3 to 5, according to the present invention, a rising wall 1 on the upper surface of one side edge of the operating member 12 is provided.
A permanent magnet 16 is embedded in the upper part of the actuating member 12 so that winning balls flowing backward on the upper surface of the actuating member 12 will not be attracted by the permanent magnet 16, which is located at the front end of the horizontal axis 9. The present invention is characterized in that a reed switch 18 is installed on one side wall 7b of the box frame 7 facing the wall 15 and operates in close proximity to and opposite to the permanent magnet 16. According to a preferred embodiment of the invention, the reed switch 18 is connected to the actuating member 1 of FIG.
The permanent magnets 16 are mounted in such a position that the permanent magnets 16 are close to each other and face each other at the position where the front end of the magnet 2 is flipped up. Although not shown, the reed switch 18 is connected via a lead wire to, for example, a solenoid or a motor for opening and operating another batted ball winning device provided on the game board surface, thereby forming a predetermined electric circuit. .

Therefore, according to this embodiment, the movable pieces 3, 3
When the actuating member 12 is in the horizontal position as shown in FIG. 3, the reed switch 18 is separated from the permanent magnet 16 and is not subjected to magnetic action, opening the electric circuit. From this state, when the operating member 12 tilts as shown in FIG. 4 under the weight of the ball, the permanent magnet 16 approaches and opposes the reed switch 18, so the reed switch 18 receives the magnetic action of the permanent magnet 16 and conducts electricity. Close the electrical circuit. At this time, the magnet body 13 of the actuating member 12 is attracted to the magnetic rod 14 to securely hold the rear end thereof. Therefore, there is no risk of the actuating member 12 moving blindly and causing a miss pulse such as hitting the reed switch 18 twice. And the actuating member 12 is the third
By returning to the horizontal position shown in the figure, the permanent magnet 16 separates from the reed switch 18 and opens the electric circuit again.As the actuating member 12 reciprocates, the permanent magnet 16 approaches and opposes the reed switch 18 and separates again. This operation is repeated to open and close a predetermined electrical circuit.

By having the above-described structure and operation, the present invention can reliably open and close a predetermined electric circuit in conjunction with the reciprocating movement of the actuating member 12 that can open and close the movable pieces 3, 3. According to the present invention, a reed switch 18, which is operated by the permanent magnets 16 provided on the actuating member 12 coming close to each other, is provided on one side wall 7b of the box frame 7 at a predetermined distance from the actuating member 12. Therefore, reed switch 1
8 mounting positions can be freely set over a wide range,
Therefore, in addition to the embodiment described above, for example, when the front end of the actuating member 12 is lowered and the movable pieces 3, 3 are in an upright state, the reed switch 18 is operated to close the electric circuit, or the reed switch 18 is configured to close the electric circuit. Part 1
It is also possible to easily operate the reed switch 18 instantaneously during the reciprocating movement of the reed switch 2. By making the mounting position of the reed switch 18 freely movable in this way, it goes without saying that the desired effect can be exerted accurately.
It becomes possible to use the pachinko machine in accordance with various conditions, and especially when used in combination with a plurality of other hit ball winning devices, it is possible to easily provide a pachinko machine with interesting game content.

Moreover, since the reed switch 18 is attached to the side wall of the box frame 7, the impact caused by the reciprocating motion of the actuating member 12 is not directly applied to the winning ball flowing on the upper surface of the actuating member 12. Since there is no possibility of collision, it can be used for a long period of time without fear of damage.

As described above, according to the present invention, there is no risk of miss pulses occurring, and by changing the mounting position of the reed switch, it can be used over a wide range of conditions to meet various conditions. There are various effects such as no damage to the switch, high durability and practicality.
