Description

[Detailed description of the invention] This invention relates to a safe ball receiving device that raises and lowers a pair of wing pieces to increase or decrease the chances of a batted ball becoming a safe ball. In addition to making pachinko play more interesting than ever before, by effectively utilizing the attraction force of the magnet to hold the wings when raising and lowering the ball, the ball will not become a safe ball. The aim is to make pachinko games fairer by preventing players from inadvertently falling down.

Conventional safe ball receiving devices of this type have a pair of wing pieces that are pivotally supported with the center of gravity biased outward, and are connected to a control lever, etc., so that the balls can be moved through the safe ball receiving opening in the upper center and on both sides of the lower part. A device in which a pair of winglets raise and lower at the same time or alternately each time a ball enters the opening and becomes a safe ball is generally used, but over many years of use, there is no change in the chance of a ball becoming a safe ball. The lack of newness has significantly reduced the interest in pachinko games, and the rotational interaction between the pair of wing pieces and the control lever due to their own weight, as well as the gravity of the safe ball, causes the wing pieces to rise and fall, and these are engaged and disengaged. Since the blade is held in place by a blade, it has the disadvantage that it often unintentionally tilts up and down due to impact, vibration, etc., such as when a ball hits the blade.

In order to eliminate such conventional drawbacks, this invention has a safe ball receiving port in the upper center, openings on both sides of the lower part, a safe ball outlet passage below the opening, and a safe ball receiving port. The wing pieces for opening and closing the safe ball receiving case, in which the safe ball falling passage provided at the rear of the case is communicated with the safe ball falling passage through the guide gutter, are pivoted outward so that they can be freely raised and folded. At the same time, an actuating body that integrally forms a support piece that holds the wing piece in an upright position and a ball receiving piece that is pushed down by receiving a safe ball that has entered the opening is attached to the proximal protrusion piece of the wing piece. The pivot is arranged so that it can freely rotate back and forth within a certain angle range in relation to the
Furthermore, a long hole in which the magnets are fixed facing each other vertically is drilled in the safe ball receiving case, and a suction rod fixed to the support piece of the actuating body is inserted into the long hole with its tip protruding to the rear. A suction rod is provided to attract and hold the magnet at the upper limit and lower limit positions of rotation of the support piece, and a lifting piece is provided at the tip of the lower rear part of the safe ball receiving case to separate the suction rod from the magnet and lift it up. At the rear end, a movable body facing the safe ball falling path and equipped with a push-down piece that can be pushed down in response to the safe balls flowing down the safe ball falling path is pivoted freely with the center of gravity shifted forward. This structure has made pachinko games more interesting than ever before, and has also made pachinko games fairer by ensuring smooth and reliable raising and lowering of the wings and strengthening the holding force when raising and lowering them. be.

Hereinafter, one embodiment of the safe ball receiving device for a pachinko machine according to this invention will be explained in detail based on the drawings. In the drawing, A has a safe ball receiving opening 1 in the center of the upper part and openings 2 and 2' on both sides of the lower part. A safe ball outlet passage 3, 3' is formed in the lower part of the opening part 2, 2' in communication with the opening part 2, 2', and a safe ball outlet passage 3, 3' is provided in the lower part of the opening part 2, 2', and a safe ball outlet passage 3, 3' is provided in the lower part of the opening part 2, 2'. It is a safe ball receiving case in which a falling passage 4 is communicated via a guide gutter 5, and both openings 2, 2'
The safe balls that have entered the safe ball outlet 1 are guided to the safe ball outflow passages 3, 3' directly below the safe ball outlet 1, and the safe balls that have entered the safe ball receiving opening 1 are guided to the safe ball drop passage 4 located at the rear. 6 and 6' are wing pieces that are freely pivoted up and down by pivots 17 and 17' at the openings 2 and 2' on both sides of the safe ball receiving case A, and have projecting pieces 10 and 1 at their base ends.
0 is integrally formed, and its center of gravity tends to be biased outward and always tilted in an inverted V shape. When the blades 6, 6' are tilted, the engaging portions 6a, 6
a' is engaged with the side end of the front plate 23 of the safe ball receiving case A, so that it is always held in a tilted state at a constant angle. 9 and 9' are support pieces 7 and 7' for holding the wing pieces 6 and 6' in an upright position, and wing pieces 6 and 9'.
It is an actuating body integrally equipped with ball receiving pieces 8, 8' which are pushed down by the safe balls that enter the openings 2, 2' when tilting the ball 6'. It is pivoted so that it can freely rotate back and forth,
The supporting pieces 7, 7' are connected to the proximal projecting pieces 1 of the wing pieces 6, 6'.
Opening 2, located near the rear on 0,10'
The gravity of the safe ball that has entered 2' pushes down the ball receiving pieces 8, 8' together with the proximal projecting pieces 10, 10' of the wing pieces 6, 6', and moves the actuating bodies 9, 9' in a certain direction at a certain angle. The wing piece 6, which is in a tilted state by rotating within a certain range,
6' is raised to close the openings 2, 2'. 11, 11' is safe ball receiving case A
Adsorption rods 13, 13', which are magnets fixed oppositely to each other at the upper and lower sides of elongated holes 12, 12' drilled in the holes 12, 12', fixed to the supporting pieces 7, 7' of the actuating bodies 9, 9', The suction rods 13, 13' are inserted into the holes 12, 12' and their tips protrude to the rear, and the suction rods 13, 13' are attracted and held by the magnets 11, 11' at the rotational upper limit position of the support pieces 7, 7'. , 6' are firmly held in the upright position, and the suction rods 13, 13' are held firmly by the magnets 11, 13'.
By being adsorbed and held by 11', the actuating body 9,
The reciprocating rotational position within a certain angle range of 9' is regulated. Reference numeral 16 indicates that the adsorption pieces 13, 13' are adsorbed and held by the lower magnets 11, 11', and the wing pieces 6, 6' in an upright shape are tilted by the safe ball that has entered the safe ball receiving port 1 in the center of the upper part. It is a movable body and consists of a tip lifting piece 14 and a rear end pushing piece 15, with the lifting piece 14 facing the lower part of the rear protrusion of the suction rods 13, 13', and the pushing piece 15 facing the safe ball falling path 4. It is rotatably mounted at the rear lower part of the safe ball receiving case A by a pivot 19, and is made to be heavier on the front end side and heavier on the rear end side to enable automatic return. In addition, in the figure, 20 is a safe ball guide protrusion continuously provided at the center of the bottom of the safe ball receiving port 1 and guide gutter 5 of the safe ball receiving case A, and 21, 21' are safe ball outlet channels 3, 3'. A safe ball guide protrusion is provided at the center of the bottom of the ball.These are intended to reduce the contact area of the safe ball and make it roll easily.
Further, 22 is a receiving piece for the movable body 16, 24, 2
Reference numeral 4' denotes a collision guide that guides the safe balls provided in the openings 2 and 2' downward.

In the above configuration, when both wing pieces 6, 6' are tilted to open both side openings 2, 2' (see the solid line state in Figs. 1 to 4), a ball is struck from one of them. When the safe ball enters the opening 2 diagonally from above and becomes a safe ball, the safe ball falls downward via the collision guide 24 and lands on the ball receiving piece 8 of the actuating body 9 and the proximal projection piece 10 of the wing piece 6. The ball receiving piece 8 and the proximal protruding piece 10 rest on each other.
are pushed together by the gravity of the safe ball, and the suction rod 13 is held by the upper magnet 11 at the upper limit rotation position.
is detached from the magnet 11 and the actuating body 9 is rotated counterclockwise within a certain angle range, and the blade 6 is rotationally displaced in an upright manner to close one opening 2. At this time, when the support piece 7 reaches its rotational lower limit position, the suction rod 13 is attracted and held by the lower magnet 11, so that its tip supports the inside of the proximal protrusion piece 10 of the wing piece 6 that is erected. The proximal protruding piece 10 of the wing piece 6 is held between the upper end stopper part 3a of the outer wall of the safe ball outflow path 3 and the wing piece 6 is held stably. (See the chain line in FIG. 1 and the solid line in FIG. 5). Then, the safe balls that have activated the operating body 9 and the wing pieces 6 flow through the safe immediately below them into the outflow path 3, and are led out from the safe ball outflow path 3 to the back (see arrow a in FIG. 3).
Note that when a ball hits the other opening 2' and becomes a safe ball, the wing 6' rises up to close the other opening 2' and stabilize the wing 6'. to be maintained.

Next, when the wing pieces 6, 6' are both upright and the openings 2, 2' on both sides are closed (see solid lines in Figure 5), the ball enters the safe ball receiving port 1 in the upper center. When the ball becomes a safe ball, the safe ball rolls backward through the guide gutter 5 and falls through the safe ball falling path 4 at the rear (see arrow b in FIG. 4). When the safe ball falls down the safe ball falling path 4, it hits the push-down piece 15 of the movable body 16 and the push-down piece 15 is pushed down by the gravity of the safe ball, so the movable body 16 is moved as shown in FIGS. 3 and 4. The tip lifting piece 14 rotates clockwise.
At this point, the suction rods 13, 13' are separated from the magnets 11, 11', the lifting actuating bodies 9, 9' are rotated in the opposite direction, and the proximal protrusions of the wing pieces 6, 6' are removed by the supporting pieces 7, 7'. 1
0 and 10' are released, the blades 6 and 6' rotate outward under their own weight and open the openings 2 and 2' (see solid lines in FIG. 1). At this time, the suction rods 13, 13' are at the upper limit rotation position of the support pieces 7, 7', and the upper magnets 11,
11', the actuating bodies 9, 9' do not unnecessarily rotate in the direction of raising the blades 6, 6', that is, downward, and the blades 6, 6' are stably held in a tilted state. It is.

In addition to the above-mentioned raising and lowering operation, after the ball enters one of the openings 2 or 2' and raises only one wing piece 6 or 6', the ball enters the safe ball receiving opening 1 in the upper center.
When the ball enters the ball, only one of the wing pieces 6 or 6' is tilted, so depending on the order in which the ball is supplemented, both wing pieces 6 and 6' may be tilted.
rises and falls alone. Furthermore, even if a ball enters the safe ball receiving port 1 in the upper center when both wing pieces 6, 6' are tilted, both wing pieces 6, 6' will not stand up.
This does not narrow the scope of the supplement.

As explained above, this invention not only allows the pair of wing pieces to be raised and lowered separately, but also allows them to be tilted at the same time, making pachinko games more interesting than ever before. The magnetic adsorption force holds the wing pieces firmly and securely when they fall down, eliminating the possibility of the wing pieces inadvertently lifting up due to shocks, vibrations, etc. caused by a ball hitting the wing piece, making pachinko games fairer. This has the effect of maintaining the Further, since the structure is extremely simple, it is possible to achieve proper operation and cost reduction.
