The present invention relates to a variable safe ball socket for pachinko machines configured as follows.

[Prior Art] Conventionally, a protruding piece was provided at the rear end of a ball guiding plate that controlled the upright and tilting of the movable wing pieces, and the protruding piece was pushed down by a ball passing through the back of the game board to make the movable wing stand up. A variable safe ball socket having a structure in which movable blades can be tilted is known, for example, from Japanese Utility Model Publication No. 51-28205.

In addition, there is also a variable safe ball socket in which a protruding piece provided at the rear end of the ball guiding plate is pulled upward by a power member such as a solenoid and the tilted movable blade can be erected. This has already been proposed in Publication No. -95781.

[Problems to be solved by the invention] However, these variable-safe ball receivers are limited to either tilting the upright movable blades or raising the tilted movable blades; There were restrictions on its use, and it had little practical value.

[Means for solving the problem] The present invention has an actuating piece having front and rear engaging recesses on the side surface of a guide box provided on the rear surface of the mounting board, and a protrusion that can engage with the engaging recess. The lever piece is swingably provided, one end of the actuating piece is pivotally connected to the rear end of the ball guide plate, and the lever piece is always held in an upper position by a spring so that the protrusion is disengaged from the engagement recess of the actuating piece. When the movable wing piece is upright, the protrusion is adapted to be able to press down against the engagement recess on one side of the actuating piece, and when the movable wing piece is tilted, the actuating piece is pressed down. It is constructed so that it can be pushed down to correspond to the other engagement recess.

[Operation] When the movable wing piece is upright, when the lever piece is pressed down, its protrusion engages with the engagement recess on one side of the actuating piece, pushing the rear end side of the actuating piece downward from the shaft. Push down the rear end of the guide plate to tilt the movable blade. Also, when the movable wing piece is tilted, when the lever piece is pressed down, its protrusion engages with the other engagement recess of the actuating piece, pushing the front end side of the ball guiding plate downward from the axis of the actuating piece. Pull up the rear end of the movable wing to make it stand up.

Inside the guide box 6, there is a seesaw-operating ball guiding plate 8 having a ball receiving piece 7 at the tip, and a horizontal shaft 9. The ball guiding plate 8 is held in a substantially horizontal position with its tip lowered, and its tip is held in an upright position shown by the solid line in FIG. At the same time, the tip portion is tilted upward to tilt the movable wing pieces 3, 3 in an inverted eight-shape as shown by the chain line in the figure. A ball outlet 10 is provided on one rear side of the guide box 6 through which the balls flowing backward on the upper surface of the ball guiding plate 8 flow out, and a notch 11 is provided on the other side, so that the rear end of the ball guiding plate 8 is provided with a notch 11 on the other side. An engagement pin 12 protruding outward from the notch 11 is provided on the side.

Reference numeral 13 denotes an actuating piece pivotally supported on one end of a horizontal shaft 9 protruding outward from the other side of the guide box 6 opposite to the ball outlet 10. A horizontal guide groove 14 is formed at the rear end. Engagement recesses 1 are provided on the edge at the front and back positions of the horizontal shaft 9.
5 and 16 are formed. The engagement pin 12 of the ball guide plate 8 is inserted into the guide groove 14 to pivotally connect the ball guide plate 8 and the operating piece 13 together. 17 is actuating piece 1
3 and the front end is attached to the side of the guide box 6.
The lever piece is pivotably supported by a lever 8 and has a protrusion 19 that can be engaged with the engagement recesses 15 and 16 of the actuating piece 13. Further, the lever piece 17 is rotated upwardly by a spring 20 so that the protrusion 19 is always placed in a position where it is disengaged from the engagement recesses 15 and 16 of the actuating piece 13, as shown in FIG. . The upper end of the protrusion 19 is rotatably attached to the lever piece 17 by a shaft 21, and a permanent magnet 22 is fixed near the lower end. Also, protrusion 1
As shown in FIG. 5, when the movable blades 3, 3 are upright, the movable blade 9 corresponds to the engagement recess 15 of one of the actuating pieces 13 so as to be able to be pushed down, and as shown in FIG. When the piece is tilted, it can be pressed down against the other engaging recess 16 of the actuating piece 13. 23
and 24 are stoppers that protrude upward so that the protrusions 19 come into contact at the front and back positions of the engagement recesses 15 and 16. Magnetic pieces 25 and 26 are fixed to these stoppers so that they can attract the permanent magnets 22. Therefore, the engagement between the protrusion 19 and the engagement recesses 15 and 16 is ensured and facilitated.

In the variable safe ball socket having the above configuration, when the lever piece 17 is placed in the upper position shown in FIG. The ball flows rearward on the upper surface of the guide plate 8, lowers the rear end by the weight of the ball, flips up the tip, tilts the movable blades 3, and flows out from the ball outlet 10. At this time, the actuating piece 13 also swings together with the ball guiding plate 8 as shown by the chain line in FIG.
Since it is placed in an upper position away from 5 and 16, it does not interfere with its operation. Then, when the ball B ₁ enters between the tilted movable blades 3, 3, it causes the movable blades 3, 3 to stand up and the ball receiving piece 7 of the ball guide plate 8.
The tip of the ball guide plate 8 is lowered by the weight of the ball and intervened below the shafts 4, 4 of the movable blades 3, 3 to maintain its upright position. At this time, the actuating piece 13 is also connected to the ball guide plate 8.
