Description

  The present invention relates to a ball stopper device for a transfer rod of a pachinko game machine, and in particular, a transfer that can reliably stop the flow of a game ball by allowing a ball stop piece to enter a passage in the transfer rod from below the bottom wall. The present invention relates to a ball stopper.

  A prize ball tank is provided on the upper part of the mechanism plate of the pachinko machine, and the prize balls sent from the island enter this prize ball tank. The prize balls stored in the prize ball tank are sent out in alignment with a transfer rod connected to the lower part of the prize ball, and the prize balls transferred in a substantially horizontal state through the transfer rod pass through the guide rail on the downstream side. It is sent to a prize ball payout device connected below. When a game ball is won, a predetermined number of prize balls are paid out by the operation of the prize ball payout device.

  By the way, when inspecting or repairing the prize ball dispensing device, it is necessary to stop the prize balls to be transferred to the transfer basket. As a ball stop device for stopping the flow of the ball, a ball stop device for a transfer rod of a pachinko machine described in Patent Document 1 below is conventionally known.

In this conventional ball stop device, a single support shaft is attached in the transverse direction of the rail above the rail portion of the transfer rod, and a ball stop piece bent in a substantially L shape is provided on the support shaft. The stop member is pivotally supported so as to be swingable, and a spring member for biasing the ball is fitted on the support shaft. The ball stop member holds the ball stop stationary position where the ball stop piece is stably stopped outside the transfer rod at the time of non-ball stop operation. When the ball stop member is stopped at the ball stop, the spring member Due to this urging force, the ball stop member is configured to enter the ball stop piece so as to push it down from above the transfer rod to stop the flow of the prize ball.

  However, when this type of conventional ball stopper is operated to stop the ball stopper member, the ball stopper piece enters between the pachinko ball and the pachinko ball that are fed in alignment in the rail. In this case, there is no problem, but the ball stop piece touches the top of the pachinko ball at the time of ball stop operation, and the ball stop piece does not completely enter the rail. If it is sandwiched between the bottom wall of the ball, the ball stop member may stop in an incompletely pushed state. In this state, the pachinko ball held by the tip of the ball stop piece is released and discharged, or the ball stop member is pushed back to the non-ball stop position by the pressure of the prize ball sent through the rail part. There was a problem that the ball stopping operation was released.

  This invention solves the above-mentioned subject, and it aims at providing the ball stop apparatus of the transfer basket of the pachinko game machine which can stop the transfer of the game ball in a transfer basket reliably.

  The ball stop device for the transfer rod of the pachinko gaming machine of the present invention is a ball stop device for the transfer rod of the pachinko game machine that stops the transfer of the game ball sent from the prize ball tank and flowing down in the transfer ball A ball stop member is pivotally supported on the lower side, and the ball stop member is provided with a ball stop piece that enters a passage in the transfer rod through a long hole provided in the bottom wall of the transfer rod. The ball stop piece is caused to enter the passage so as to push up from the long hole in the bottom wall of the passage to stop the movement of the game ball.

  Here, in the ball stop device, a spring member is attached to the ball stop member, and the ball stop member is rotated between the ball stop position and the non-ball stop position by the spring member, and the ball stop position and the ball stop position are stopped. It can be biased to be stationary at both positions.

  In addition, a cover part for leveling the game ball can be provided on the upper surface of the transfer bowl, and the height of the cover part from the bottom wall is about 1.5 to about 2 times the diameter of the game ball. It is preferable to set in the range.

  The long hole is also used as a dust discharge hole for dropping dust provided on the bottom wall of the transfer rod, and the ball stop member is pivotally supported via a support shaft with respect to the attachment portion. It can be formed integrally with the bottom wall.

  The ball stopper device of the transfer rod having the above structure normally maintains a non-ball stop state in which the ball stop member has withdrawn the ball stop piece from the passage of the transfer rod, and from the prize ball tank to the inside of the transfer rod. The game balls sent to are flowed down in sequence in the passages in the transfer basket and sent to the prize ball payout device.

  When stopping the flow of the prize ball of the transfer rod during inspection or repair of the prize ball dispensing device, manually rotate the ball stop member and remove the ball stop piece from the slot in the bottom wall of the transfer rod. Enter the passage. At this time, even when the tip of the ball stop piece hits the game ball in the passage, the tip of the ball stop piece enters the passage from the lower side, so the game ball easily moves before or after the ball stop piece, As in the past, the game ball is not sandwiched between the tip and the bottom wall of the ball stop piece, and the ball stop piece of the ball stop member reliably enters between the game ball and the game ball, The game ball can be stopped reliably. Further, the ball stop member does not stop entering the passage of the ball stop piece in the middle, and the problem that the ball stop member is pushed back to the non-ball stop position by the pressure of the game ball flowing down is prevented.

  In addition, a spring member is mounted on the ball stop member, and the ball stop member is rotated between the ball stop position and the non-ball stop position by the spring member and is stationary at both the ball stop position and the non-ball stop position. If it is set as the structure biased in this way, ball stop operation and ball stop release operation can be performed easily.

  In addition, when a cover part for leveling the game ball is provided on the upper surface of the transfer rod, the height of the cover part from the bottom wall is in a range of about 1.5 times to about 2 times the diameter of the game ball. If set, it is possible to eliminate the problem that the game ball is sandwiched between the cover portion.

  The long hole is also used as a dust discharge hole for dropping the dust in the transfer rod, and the ball stop member is pivotally supported to the mounting portion via a support shaft, and the mounting portion is integrated with the bottom wall of the transfer rod. If formed, the structure of the ball stopper can be simplified, and the number of processing steps during manufacturing can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a rear view of the pachinko gaming machine. In FIG. 1, reference numeral 1 denotes a wooden frame of a pachinko machine. A front frame 2 is attached in front of the wooden frame 1 through a hinge so as to be opened and closed, and a glass door (not shown) is provided on the front surface of the front frame 2 so as to be opened and closed. A metal frame is attached, and the game board 3 is detachably attached to the inside of the front frame 2. Further, a mechanism plate 4 made of synthetic resin is rotatably mounted on the back side of the game board 3 via a hinge.

  A prize ball tank 5 for storing a prize ball for payout is attached to the upper part on the back side of the mechanism plate 4. On the lower side of the prize ball tank 5, a transfer rod 6 is arranged connected to the bottom of the prize ball tank 5, and the prize balls stored in the prize ball tank 5 are made to flow down to the transfer rod 6 in order. . The transfer basket 6 is attached with the upstream side connected to the prize ball tank 5 and the downstream side inclined slightly downward, and in the transfer basket 6 there are two rows of passages 7 in the longitudinal direction across the partition wall 7d. Are formed along.

  As shown in FIG. 4, a long hole 7b is formed in the longitudinal direction in the bottom wall 7a near the left end (tip) portion in the passage 7 of the transfer rod 6 for allowing the prize ball to flow freely from left to right in FIG. ing. The long hole 7b is provided as a dust hole for dropping dust that has entered the passage 7 and as an insertion hole for allowing a ball stop piece of a ball stop device 10 to be described later to enter.

  Further, as shown in FIG. 4, a groove 7 c is formed in a straight line along the flow-down direction of the passage at the center of the bottom wall 7 a of the passage 7 of the transfer rod 6, and the prize ball is a bottom wall 7 a of the passage 7. When the balls flow down in a row, the award balls flow down linearly along the grooves 7c while maintaining a slight gap between the left and right walls. The two long holes 7 b are formed in the grooves 7 c of the passages 7.

  Further, a ball stop device 10 for stopping a prize ball flowing down the transfer rod 6 is disposed below the long hole 7b of the bottom wall 7a of the transfer rod 6. This ball stop device 10 allows a ball stop piece 14 at the tip of the ball stop member 11 to enter the passage 7 by manual operation. As shown in FIGS. 2 and 3, the mounting portion 12 and its mounting portion 12 are provided. The support shaft 13 is supported by the support arm 12a, and the ball stop member 11 is pivotally supported by the shaft 13 so as to be rotatable.

  The ball stop member 11 is formed by protruding ball stop pieces 14 on both sides of the end of the plate-like main body, and the upper portion of the plate-like main body is pivotally supported with respect to the support shaft 13. The ball stop piece 14 is formed by the long hole 7b. It is formed in such a thin thickness that it can enter, and is inclined to the plate-like main body so as to be inclined in a substantially square shape. Further, a spring member 15 (coil spring) is applied between one side portion of the plate-like main body of the ball stopper member 11 and the attachment portion 12.

  The spring member 15 is attached so that the ball stop member 11 is stably stopped at both the non-ball stop position (the upper diagram in FIG. 6) and the ball stop position (the lower diagram in FIG. 6). That is, one end of the spring member 15 is hooked to the mounting portion 12, the other end of the spring member 15 is hooked to the ball stopper member 11, and the spring is rotated during rotation about the support shaft 13 of the ball stopper member 11. The member 15 is mounted so as to move before and after the axial center position of the support shaft 13. That is, as shown in FIG. 2, when the spring member 15 is positioned on the left side as shown in FIG. 2 from the axial center position of the support shaft 13, the ball stop member 11 is biased to the non-ball stop side, and the spring member 15 When it is located on the right side of the shaft center position of the support shaft 13 as shown in FIG. 3, the ball stop member 11 is biased toward the ball stop side.

  As shown in FIGS. 4 and 5, the leading end of the transfer rod 6 has two rows of passages 7 which are bent downward and open, and a ball passage 9 is provided below the open end of the passage 7 of the transfer rod 6. The prize ball payout device 8 is attached to the mechanism plate 4, and the prize ball that has flowed down the transfer rod 6 is sent from the ball passage 9 to the prize ball payout device 8.

  The mounting portion 12 of such a ball stopper is attached to the mechanism plate 4 at the lower position of the bottom wall 7a of the transfer rod 6 with its support shaft 13 facing the transverse direction of the passage 7 in the rod, and its support The support shaft 13 is held and attached between the arm 12a and the mechanism plate 4. The ball stop member 11 of the ball stop device in the attached state causes the ball stop piece 14 to enter the passage 7 from the long hole 7b when rotating counterclockwise in FIG. The ball stop piece 14 is attached so that the tip end of the ball stop piece 14 faces the upstream side in the passage 7 and the plate-like main body of the ball stop member 11 comes into contact with the bottom wall 7a and stops.

  As shown in FIG. 4, the ball stopper of the transfer rod 6 having the above structure is a non-ball in which the ball stopper member 11 has its ball stop piece 14 positioned outside the passage 7 of the transfer rod 6 as shown in FIG. 4. The stop state is held, and the state is held by the spring member 15 (the upper diagram in FIG. 6). In the non-ball-stopped state, the game balls sent from the prize ball tank 5 into the transfer basket 6 flow down in order in the passage 7 in the transfer basket 6 and are sent to the prize ball payout device 8.

  On the other hand, in order to stop the prize ball from flowing down the transfer rod 6 during inspection or repair of the prize ball dispensing device 8, the ball stop member 11 is manually rotated counterclockwise in FIG. The ball stop piece 14 is caused to enter the passage 7 through the long hole 7b formed in the bottom wall 7a of the transfer rod 6 (the middle diagram in FIG. 6). The rotation of the ball stop member 11 is urged by the spring member 15 from a position where the position of the spring member 15 exceeds the axial center position of the support shaft 13, and can be reliably rotated to the stop position.

  Then, in the vicinity of the rotation end of the ball stop member 11, two ball stop pieces 14 enter the respective passages 7 from the long holes 7b of the bottom wall 7a, and a part of the plate-like main body of the ball stop member 11 is the bottom. As shown in the lower part of FIG. 6, the ball stop piece 14 stops obliquely upward toward the upstream side as a result of being in contact with the wall 7a.

  Thus, when the ball stop piece 14 enters the passage 7, the game balls are aligned and positioned at the corresponding positions in the passage 7 as shown in the middle diagram of FIG. 6, and the tip of the ball stop piece 14 is in the passage 7. When the player hits the game ball, the game ball easily moves before or after the ball stop piece 14, so that the game ball is not pinched between the ball stop piece 14 and the other fixing portion. Then, when a part of the plate-like main body abuts against the bottom wall 7 a, the ball stop member 11 is in a state where the ball stop piece 14 is stopped obliquely upward on the upstream side, thereby being aligned in the passage 7. The played game ball hits the ball stop piece 14 and stops as shown in the lower diagram of FIG.

  On the other hand, when the movement of the game ball is resumed by setting the passage in the transfer rod 6 to the non-ball stop state, the ball stop member 11 is rotated clockwise from the state shown in the lower part of FIG. Is withdrawn from the passage 7. At this time, the rotation of the ball stop member 11 is urged clockwise by the spring member 15 from a position where the position of the spring member 15 exceeds the axial center position of the support shaft 13, and is not as shown in the upper diagram of FIG. It can be reliably rotated to the ball stop position and the state can be maintained.

  Thus, according to the present ball stop device, the ball stop piece 14 of the ball stop member 11 is made to enter the passage 7 from the lower side of the transfer rod 6, that is, through the long hole 7b provided in the bottom wall 7a. In order to enter the passage 7 from the lower side of the game balls to be aligned, the game ball is not sandwiched between the tip of the ball stop piece 14 and the other fixed portion, and the ball stop piece 14 of the ball stop member 11 Surely enters between the game balls. Therefore, in a state in which the ball stop piece 14 of the ball stop member 11 has entered the passage 7 in the middle, there is no phenomenon of being pushed back by the falling pressure of the game ball, and the game ball in the transfer basket is surely stopped. Can do.

  Also, the spring member 15 mounted between the mounting portion 12 and the ball stop member 11 causes the ball stop member 11 to rotate between the ball stop position and the non-ball stop position, and the ball stop position and the ball stop position. Since it is urged to stop at both positions, the ball stop operation and the ball stop release operation can be easily performed, and both the operation states can be reliably maintained. Further, since the long hole 7b for allowing the ball stop piece 14 to enter can also be used as a dust discharge hole for dropping the dust in the transfer rod 6, it can be manufactured at a low cost with fewer processing steps.

  FIG. 7 shows another embodiment. In this embodiment, a cover portion 16 is attached to the downstream end portion of the transfer rod 6 so as to cover the upper opening portion of the passage 7. The cover portion 16 of the passage 7 is provided for leveling a large number of game balls flowing down the passage 7 and overlapping at the tip thereof, and the upstream side is curved upward slightly. Is formed. Further, as shown in FIG. 7, the height h of the cover portion 16 from the bottom wall 7a is set in a range of about 1.5 to about 2 times the diameter of the game ball. In this way, by setting the height h of the cover portion 16 within a range of about 1.5 times to about twice the diameter of the game ball, the game ball is placed between the tip of the ball stop piece 14 and the cover portion 16. It is possible to solve the problem that is caught between the two. Further, when a large number of game balls flow down and overlap each other, the game balls can be leveled well so that the game balls are not easily sandwiched between the bottom wall 7 a and the cover portion 16.

  In the above embodiment, the attachment portion 12 is fixed to the surface of the mechanism plate 4 and one end of the support shaft 13 is pivotally supported by the support portion fixed to the surface of the mechanism plate 4. 6 can be formed integrally with the bottom wall 7a, and the support shaft of the ball stop member can be pivotally supported at both ends by the mounting portion. According to this, the structure of the ball stopper can be simplified, and the number of processing steps during manufacturing can be reduced.

  As described above, according to the ball stopping device of the transfer rod of the present invention, even when the ball stopping member is rotated during the ball stopping operation and the tip of the ball stopping piece hits the game ball in the passage, Since the tip of the stop piece enters the passage from below, the game ball easily moves before or after the stop piece. Therefore, the game ball is not sandwiched between the tip and the bottom wall of the ball stop piece, and the ball stop piece of the ball stop member surely enters between the game ball and the game ball, and the game ball in the transfer basket Can be stopped reliably. Further, the ball stop member does not stop entering the passage of the ball stop piece in the middle, and it is possible to prevent the ball stop member from being pushed back to the non-ball stop position by the pressure of the game ball flowing down.
