[Detailed Description of the Invention] <Industrial Application Field> This invention relates to an upper tray ball extraction mechanism for a Pachinko machine that moves balls accumulated in the upper tray of a Pachinko machine to a lower tray.

<Prior Art> As is well known, pachinko machines are provided with a ball extraction mechanism for transferring balls accumulated in an upper tray to a lower tray. This ball extraction mechanism was developed in the 1980s, for example.
As shown in Publication No. 138584, a sliding groove is provided at the end of the upper plate, an opening/closing plate is slidably provided in the sliding groove, and a pressing rod is rotatably pivoted above the sliding groove. The lower end of the connecting lever provided at the bottom of the pressing rod is located below the sliding groove, and the intermediate part of the operating lever is pivoted below the sliding groove, so that the operating lever is The upper end of the operating lever is connected to the pressing rod, and the lower end of the operating lever is connected to the lower end of the pressing rod, so that when the pressing rod is pressed, the opening/closing plate is slid and the ball is extracted. It is something.

<Problem to be solved by the invention> However, in the conventional ball extraction mechanism, the pressing rod must be continuously pressed when extracting the ball. Therefore, the game is often interrupted in order to remove the ball. Furthermore, in order to remove all the balls from the upper and lower trays in order to move the table or stop the game, the ball extraction mechanisms of the upper and lower trays must be operated alternately, which is troublesome.

In addition, since the conventional ball extraction mechanism has a sliding part, the structure is complicated and difficult to manufacture, and the sliding part is easily clogged with cigarette ash and dirt, making maintenance and inspection complicated. .

<Means for Solving the Problems> This invention was proposed in view of the present invention and the above, and in an upper plate of a pachinko machine having a guide tub for lining up balls in a line and guiding them to a ball feeding control device, the above-mentioned guide tub is A ball removal chamber is formed below, which communicates with the opening provided in the guide tub, and the ball removal chamber includes a first swinging member having a ball receiving portion that can close the opening, and the first swinging member. A second ball that can receive the ball acting on the moving member.
A first locking/disengaging member and a second locking/disengaging member constituting a locking/disengaging mechanism that mutually restricts the rotation of the other swinging member are housed in a swingable manner. and a first biasing means and a second biasing means for biasing both swinging members in a direction opposite to the direction of rotation by the ball, and the second swinging member has an externally operable release member. When the ball receiving portion of the first swinging member closes the opening of the guide tub, the first locking and disengaging member of the first swinging member and the second locking and disengaging member of the second swinging member are connected to each other. The first swinging member is locked to prevent rotation of the first swinging member due to the ball pressure of the guide tub, and by operating the release member, the second swinging member is once rotated to separate the first locking and disengaging member from the second swinging member.
When the locking with the locking/disengaging member is released, the first swinging member rotates due to the weight of the ball resting on the ball receiving part, releases the opening, and the ball in the guide tub enters the ball removal chamber. The fluid flows in and acts on the first swinging member to maintain the rotating state of the first swinging member, and acts on the second swinging member to maintain the rotating state of the second swinging member. If the ball is removed and the ball flowing down the guide trough is broken for longer than the time required for the second swinging member to return and rotate, both swinging members are respectively returned and rotated by the urging means. Then, the first locking/disengaging member of the first swinging member and the second locking/disengaging member of the second swinging member are locked again.

<Function> The first swinging member and the second swinging member, which are swingably housed in a ball removal chamber that communicates with the guide tub of the upper plate through an opening, are rotated by the weight of the balls, and both swinging members are moved by the weight of the balls. An engaging/disengaging member provided on the movable member can be engaged/disengaged. Therefore, when the release member facing the second swinging member is operated, the locking and disengaging mechanism is unlocked and the first swinging member facing the opening rotates due to the weight of the ball, so the opening is released. You can remove the balls from the upper plate by using the Further, when the ball is interrupted for a period longer than the time required for the second swinging member to return and rotate, both swinging members return and the locking/disengaging mechanism is locked again.

Further, an opening 23 is provided at the lower end of the bottom 18 of the guide tub 11 to communicate the ball extraction chamber 22 and the guide tub 11.

A first swinging member 24 and a second swinging member 25 are swingably housed in the ball removal chamber 22. The first swinging member 24 has a ball receiving portion 26 with a flat upper surface and a weight portion 27 in which a weight is embedded, and the ball receiving portion 26 faces the opening 23 of the guide tub 11. The first swinging member 24 is pivotally attached to the base plate 21 of the ball extracting device 20 so as to be swingable about the first swing shaft 28, and
With the swing axis as a fulcrum, it is biased counterclockwise, as shown by arrow a in FIG. 4, which is opposite to the direction of rotation by the ball. Normally, the opening 23 is closed by the ball receiving part 26 while maintaining a substantially horizontal state.

Moreover, the first swinging member 24 and the second swinging member 25
is provided with an engaging/disengaging member constituting the engaging/disengaging mechanism 29. According to the embodiment of the drawing, the first engaging/disengaging member on the first swinging member 24 side is located forward on the side surface of the tip portion of the ball receiving portion 26. This is a locking pin 30 provided so as to protrude. This locking pin 30 is connected to the base plate 2 of the ball extraction device 20.
It is loosely fitted into the arc-shaped notch groove 31 opened at 1.

On the other hand, a second swing member located below the first swing member 24
The swing member 25 is swingable about the second swing shaft 32 as a fulcrum. This second swinging member 25 has a weight part 33 in which a weight is embedded and a ball receiving arm 34, and the second swinging member 25 is moved around the second swinging part shaft 32 by the weight part 33 as indicated by the arrow b in FIG. As shown, it is biased counterclockwise and is normally in a nearly horizontal state.
Further, the second engaging/disengaging member on the second swinging member 25 side is, for example, a cam piece 35 extending upwardly from the side edge of the base end portion of the ball receiving arm 34 . The cam piece 35 has an arc-shaped cam surface 36 and a steep falling surface 37, and is positioned along the front surface of the base plate 21 through a notch 38 formed in the base plate 21 of the ball extraction device 20. A locking pin 30 of the first swinging member 24 is locked to the upper end of the cam surface 36 to prevent the first swinging member 24 from rotating downward.

Furthermore, a release member 40 that can penetrate the bottom 39 of the base plate 21 of the ball extraction device 20 and protrude upward is provided on the lower surface of the weight portion 33 of the second swinging member 25 . According to the illustrated embodiment, the release member 40 includes a push button 43 having a return spring 42 provided on the lower surface 41 of the upper tray body 6 so as to be externally operable.
Although it can be operated directly by the player, it may also be operated electrically, such as a solenoid plunger.

A ball guiding shelf 44 having a gentle downward slope is provided in the middle of the ball removing chamber 22. The upper end of this ball guiding shelf 44 is raised and positioned near the lower end of the notched groove 31, and the lower end of the ball guiding shelf 44 is made to hang down to face approximately the middle of the ball receiving arm 34 of the first swinging member 24. .
Incidentally, it is preferable to provide a cushioning material 45 such as rubber at the lower end portion of the ball guide shelf 44.

In the normal state where the locking pin 30 of the first swinging member 24 and the cam piece 35 of the second swinging member 25 are locked, the opening 23 is closed by the ball receiver 26 and the ball is not held. It can be stored in the guide tub 11. In this state, operate the release member 40 momentarily to release the second
When the swinging member 25 is rotated clockwise, the locking pin 30 constituting the locking/disengaging mechanism 29 comes off the cam surface 36 of the cam piece 35, and the ball receiving portion 2 of the first swinging member 24 comes off.
The first swing member 24 rotates clockwise about the first swing shaft 28 due to the weight of the ball placed on the ball 6 , and the locking pin 30 freely moves downward within the notch groove 31 .

Then, the ball that enters the ball extraction chamber 22 from the opening 23 with the rotation of the ball receiving part 26 falls onto the ball guide shelf 44 and further falls onto the ball receiving arm 34 of the second swinging member 25. act on the second swinging member 25 to rotate the second swinging member 25 clockwise,
The ball flows into the discharge port 46 of the ball extraction chamber 22 from the tip of the ball receiving arm 34 which rolls on the ball receiving arm 34 and tilts.
In addition, the discharge port 46 is connected to the ball extraction tub 4 which communicates with the lower tray 15.
It communicates with 6'.

Therefore, while the ball is continuously falling down the guide tub 11, the first swinging member 24 is maintained in a rotating state by the ball, and the second swinging member 25 is maintained in a rotating state. . Note that when the first swinging member 24 is in the rotating state, the locking pin 30 of the first swinging member 24 comes into contact with the falling surface 37 of the cam piece 35 of the second swinging member 25, so that the second swinging member 24 is in a rotating state. The swinging member 25 cannot be rotated back.

On the other hand, when the ball in the guide tub 11 runs out, the first swinging member 24 rotates back due to the bias of the weight part 27 to close the opening 23 and remove the last ball that entered the ball removal chamber 22. When the ball falls from the tip of the ball receiving arm 34 of the second swinging member 25, the second swinging member 25 returns and rotates due to the bias of the weight portion 33. In this case, since the locking pin 30 escapes above the notch groove 31 by the return rotation of the first swinging member 25, the locking pin 30 does not come into contact with the falling surface 37 of the cam piece 35. . Therefore, the second swinging member 25 returns and rotates until the upper surface of the ball receiving arm 34 comes into contact with the lower end of the ball guide shelf 44, and the second
The cam surface 36 of the cam piece 35 of the swinging member 25 and the locking pin 30 of the first swinging member 24 are locked.

From this point on, even if a ball is placed on the ball receiving portion 26 of the first swinging member 24, the locking/disengaging mechanism 29 is locked, so the first swinging member 24 cannot rotate and the opening is closed. 23 is maintained in the closed state to store the balls.

By the way, when the balls intermittently flow down inside the guide tub 11, the time difference T1 between the balls flowing down must be smaller than the time T2 required for the balls to travel from the opening 23 to the discharge port 46 of the ball removal chamber 22. ba(T1<T2),
Before the second swinging member 25 rotates back, the next ball falls onto the ball receiving arm 34 of the second swinging member 25. Therefore, both swinging members 24, 25 are adjusted such that T1<T2.
By setting , a so-called return delay mechanism can be constructed, and if the mark is cut within a predetermined time range, it is possible to continue removing the ball without operating the release member 40 again.

Furthermore, the present invention has a stop button 47 for when it is desired to cancel the ball extraction operation midway through. It passes through the stop button 47 and the upper tray main body 6 in the front-rear direction, and the stop pin 48 at the tip can protrude into the guide tub 11. If the above-mentioned stop button 47 is operated to stop the balls flowing down the guide tub 11, the balls will not flow into the ball removal chamber 22, so that the first swinging member 24 and the second swinging member 25
is rotated back by the urging of the respective weight portions 27 and 33, and the locking pin 30 locks on the cam surface 36 of the cam piece 35 constituting the locking/disengaging mechanism 9. In this state, even if the ball is placed on the ball receiving portion 26 of the first swinging member 24 again, the first swinging member 24 does not rotate, and the balls can be stored in the dish-shaped portion 7 again.

The guide tub 11 of the upper plate main body 6 is the front plate 5
The ball feed control device 10 is connected to the ball feed control device 10 through the inlet 19. However, with the conventional upper tray, the inlet 19 may become clogged with balls and the game must be interrupted. The cause of this ball clogging is that the balls reach the inlet 19 in a two-tiered state. Therefore, in this embodiment, a double stacking prevention device 49 is provided for preventing double stacking and discharging the upper balls to the lower tray 15.

As shown in FIGS. 8 to 10, the double stacking prevention device 49 includes a removal claw 51 that guides the balls in the upper stage to a removal port 50 formed in the front plate 5, and a removal claw 51 that guides the balls that have entered the removal port 50 into the removal port 50. It has an exclusion tub 52 that guides the tray 15. The removal port 50 is the guide tub 11
is located upstream of the inlet 19 of the ball feeding control device 10, and the lower edge of the outlet 50 opens upward from the bottom 39 of the guide tub 11 by approximately the diameter of the ball. Further, the above-mentioned removal claw 51 is spaced apart from the bottom 18 by approximately the height of one ball so that the ball can pass through the guide tub 1.
It stands out within 1.

According to the double stacking prevention device 49 as described above, when there are balls stacked in two stacks flowing down the guide tub 11, the balls in the upper stage are guided to the removal port 50 by the removal claw 51 and are removed. The liquid is discharged through the tub 52 into the lower tray 15. On the other hand, the balls in the lower stage flow down following the inclination of the guide tub 11 and are sent to the ball feeding control device 10 from the inlet 19. Therefore, the ball jam caused by double stacking is eliminated, and there is no need to interrupt the game to fix the balls.
The player can concentrate on playing the game.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-mentioned embodiments, and can be implemented as appropriate as long as the configuration described in the claims for utility model registration is not changed. For example, the locking and disengaging mechanism may be configured with locking means other than the locking pin and the cam piece, or both swinging members may be biased by a spring or the like.

<Effects of the invention> The present invention includes a first swinging member and a second swinging member that are swingably housed in a ball removal chamber, and a locking and disengaging member provided on both swinging members that is Since it is possible to engage and detach the ball from the upper plate, once the first swinging member and the second swinging member are unlocked, the rotating state of both swinging members can be changed to the ball. There is no need to hold an operating lever or the like like in conventional ball extraction devices. Therefore, according to the present invention, the operation is easy, and the player can perform the ball extraction work while playing the game, allowing the player to concentrate on the game. Moreover, if the second swinging member is interrupted within the time required for the second swinging member to return and rotate, it is possible to continuously remove the balls.

In addition, since the ball extraction mechanism of the present invention does not have a sliding part, it not only has a simple configuration and is easy to create, but also does not get clogged with cigarette ash or dirt, making maintenance and inspection easy and practical. High value.
