Description

[Detailed description of the invention] This invention relates to a safe ball receiving device for a pachinko machine, and is a safe ball receiving device of a wing type that has a pair of wing pieces that can be opened and closed to widen the range of accepting balls as safe balls. , the safe balls that entered when the blades were closed were guided to the rear, and the safe balls that entered when the blades were opened were guided directly below, creating an unprecedented combination of interlocking of the safe balls with other safe ball receivers, etc. The purpose is to increase the chance of a hit ball rolling down the game board surface becoming a safe ball and to eliminate its malfunction by making the opening and closing operation of the wings by the safe ball smooth and reliable.

One embodiment will be explained in detail below based on the drawings. In the drawings, reference numerals 1 and 1' denote a pair of wings that can be opened and closed in a wide range for accepting hit balls as safe balls. The front case 2 is pivoted opposite to the upper part of the provided front case 2 so that it can rotate freely by means of support shafts 8 and 8', and its center of gravity is biased outward by weights 9 and 9', and this is always tilted outward. I'm trying to do that. The wing pieces 1, 1'
The range of rotation is restricted to a constant angle by fitting stoppers 2a, 2a' of the front case 2 into restriction grooves 1c, 1c' of the blades 1, 1'. Reference numeral 3 denotes a safe ball discharge port bored at the bottom of the front case 2, which guides the safe balls that enter when the wing blades are opened directly below. Reference numeral 4 denotes a control piece that controls the opening and closing of the pair of wing pieces 1 and 1', and is pivotally mounted at the rear lower part of the back case 10 provided on the back side of the mounting board 7 so that it can be freely rotated by a pivot 11. , whose center of gravity is the front end engaging portion 4
Coupled with the presence of the weight 12 provided at a, it is biased forward and is always urged to rotate counterclockwise. Both ends of the front end engaging portion 4a are adapted to engage and disengage from the base end portions 1a, 1a' of the wing pieces 1, 1', and the ball guide portion 4b at the rear end is adapted to engage and disengage from the base end portions 1a, 1a' of the wing pieces 1, 1'.
It is located in a safe ball discharge opening 13 on one side of the rear part of the ball to discharge the safe balls to the side, and an engaging part 4c is provided on one side near the front. Reference numeral 5 denotes an engagement piece 5b having an engagement step 5a that engages and disengages from the engagement part 4c of the wing opening/closing control piece 4, and a support protrusion 5c having a weight 14.
It is a dog-shaped locking piece located at the front lower part of the rear case 10, and its center of gravity is biased rearward, and it is biased to constantly rotate clockwise and pivots approximately at the center of the locking piece 15.
It is pivoted so that it can be rotated freely. 6
is an actuating piece having an actuating protrusion 6a whose tip slightly protrudes directly above the safe ball discharge port 3 when the blade is opened, and an engaging protrusion 6b that comes into contact with the supporting protrusion 5c of the locking piece 5, The center of gravity is biased forward and biased to constantly rotate in the counterclockwise direction, and approximately the center is centered on the pivot 1.
5 is pivoted so that it can be rotated freely. Therefore, since the locking piece 5 and the actuating piece 6 are biased in opposite directions, the supporting protrusion 5c of the locking piece 5 and the actuating piece 6
The engaging protrusion 6b is always in contact and interlocked. In addition, 16 shifts the center of gravity to the front and pivots the axis 11.
This is an interlocking piece that is pivoted so that it can be freely rotated.When the protruding shaft 16a on the rear end side is pushed down with an interlocking rod (not shown) with other safe ball receivers, etc., the push-up piece 16b on the lower front In order to push the engaging protrusion 6b of the actuating piece 6 forward, the actuating piece 6 rotates clockwise, and the actuating protrusion 6a lifts the front of the blade opening/closing control piece 4 to raise and close the pair of wings. The pieces 1 and 1' are tilted open.

In the above configuration, when the wing pieces 1, 1' are standing up and closed, if a ball hits between the wing pieces 1, 1' and becomes a safe ball, the safe ball hits the inner ball of the wing pieces 1, 1'. It is guided rearward by the guide surfaces 1b, 1b' and rests on the blade opening/closing control piece 4, and rolls backward on the blade opening/closing control piece 4 which is inclined downwardly to the rear. When the safe ball reaches the ball guide part 4b at the rear end of the wing opening/closing control piece 4, the weight of the safe ball pushes down the rear part of the wing opening/closing control piece 4, and the safe ball moves to the safe ball discharge opening 13 of the back case 10. is discharged from. When the rear part of the blade opening/closing control piece 4 is pushed down by the safety ball, its front end engaging part 4a is lifted, so that the base ends 1a, 1a' of the blades 1, 1' are moved by both ends of the front end engaging part 4a. When the holding is released, the blades 1 and 1' tilt outward by a certain angle due to their own weight since their centers of gravity are biased outward, and at the same time, the engagement piece 5 and the actuating piece 6 are attached by the weight 14. As the blade opening/closing control piece 4 moves together with the force, the blade opening/closing control piece 4 rotates clockwise, and the engaging step portion 5a of the engaging piece 5b of the locking piece 5 engages the engaging portion 4c of the blade opening/closing control piece 4. engages to support the blade opening/closing control piece 4 in the blade open position, and causes the tip of the operating protrusion 6a of the operating piece 6 to slightly protrude directly above the safe ball discharge port 3 (the first
3 and 4).

Next, when a hit ball enters between the wing pieces 1 and 1' in the tilted open state and becomes a safe ball, the safe ball pushes open the base ends 1a and 1a' of the wing pieces 1 and 1' and falls down and is activated. The tip of the operating protrusion 6a of the piece 6 is pushed down and the ball is discharged downward from the safe ball discharge port 3 immediately below. When the operating protrusion 6a of the actuating piece 6 is pushed down by the safe ball and the actuating piece 6 rotates counterclockwise, the engaging protrusion 6b pushes the support protruding piece 5c of the locking piece 5 backward, and the locking piece 5
The blade is rotated counterclockwise against the biasing force of the weight 14 to disengage the engagement step portion 5a of the engagement piece 5b and the engagement portion 4c of the control piece 4 for opening and closing the blade. The opening/closing control piece 4 rotates counterclockwise under its own weight, and the front end engaging portion 4a descends, so this, together with the push-opening operation by the safety balls of the blades 1, 1', causes the blades 1, 1' to open. The blades 1, 1' are held in the upright and closed state by cutting into the base end portions 1a, 1a' at a good timing. The locking piece 5 and the actuating piece 6 are such that the actuating protrusion 6a of the actuating piece 6 is connected to the front end engaging portion 4 of the wing opening/closing control piece 4.
Because they are supported by C, they stand by in their original positions, maintaining the clockwise biasing force, in preparation for the next operation (from the state shown in Figures 3 and 4 to (See condition).

As explained above, in this device, the safe ball that has entered between a pair of wing pieces is guided backwards when the wing pieces are closed, and directly below when the wing pieces are opened, so that other safe balls are guided by the safe ball. Since the interlocking of the receptacle etc. can be performed in a different way than before, the chance of a hit ball becoming a safe ball increases significantly, making pachinko games more interesting. Since it can be performed smoothly and reliably, malfunctions are eliminated and pachinko games can be made fairer.
