Description

  The present invention relates to a gaming machine that uses a game ball as a game medium and pays out the game ball to a ball storage tray disposed on a front frame door.

  In a gaming machine such as a pachinko machine, a front frame door with a ball storage tray on the front side is pivotally mounted on the gaming machine main body so that it can be opened in a single direction.If a predetermined condition is satisfied during a game, a predetermined number of game balls are It pays out to the ball storage tray of the front frame door. In a general gaming machine, a payout device that performs an operation of paying out a game ball is provided in the game machine main body, and the game ball paid out from the ball delivery opening that opens on the front side of the game machine main body is discharged. Further, the front frame door is provided with a ball payout outlet penetrating the front frame door in the front-rear direction, and the ball payout opening communicates with the ball discharge outlet in the closed state of the front frame door. The game ball that has flowed out flows into the ball storage tray.

  In such a gaming machine, when a ball clogging or the like occurs during a game, the front frame door is opened and the restoration work is performed. However, when the front frame door is open, the ball feeding outlet and the front of the gaming machine main body are opened. Since the ball payout outlet of the frame door is separated, if the game ball flows out from the ball delivery outlet as in the closed state, the game ball falls down to the front side of the gaming machine main body. In the conventional gaming machine, in order to prevent this, an inlet of the payout ball discharge path leading to the surplus ball storage tray at the lower part of the gaming machine main body is opened at a position immediately upstream of the ball outlet, and the front frame door A saucer-shaped sphere lead-out receiving portion projects rearwardly at the ball payout opening opening portion, and when the front frame door is closed, the ball lead-out receiving portion is fitted into the ball feed outlet to close the payout ball discharge path. Thus, the game balls paid out from the payout device are led out to the ball storage tray through the ball payout exit. In other words, in such a configuration, when the front frame door is opened, the ball lead-out receiving part is withdrawn from the ball delivery outlet, the inlet of the payout ball discharge path is opened, and game balls paid out from the payout device are exclusively discharged as payout balls. It flows into the road and is discharged to the surplus sphere storage tray.

  Moreover, in the above-described configuration, there is one provided with a shutter plate that closes the ball outlet when the front frame door is opened (for example, Patent Document 1). This shutter plate is a plate piece that is pivotally supported on the lower edge of the ball delivery outlet. When the front frame door is open, the shutter plate is erected by the urging force of the urging spring to close the ball delivery outlet. The game ball x flowing down from the apparatus is prevented from jumping out of the ball delivery outlet excessively. On the other hand, in the closed state of the front frame door, the shutter plate is pressed against the rear edge of the ball lead-out receiving portion and tilts rearward and downward, and the ball delivery port is opened.

Japanese Utility Model Publication No. 55-56684

  By the way, the shutter plate has a point to be improved. FIG. 11 is a longitudinal sectional view of a main part of a conventional gaming machine provided with a shutter plate. As shown in FIG. 11, in the conventional gaming machine, when the front frame door c is opened, the shutter plate a is gradually raised while being elastically contacted with the ball lead-out receiving portion d where the shutter plate a is retracted forward by the biasing spring. The ball delivery port b is closed. Here, since the conventional shutter plate a has a flat plate shape, as shown in FIG. 11B, the shutter plate a does not stand up smoothly when the ball lead-out receiving portion d starts to retreat forward, and the ball is drawn out. A protrusion w having a large protrusion width is formed behind the rear edge of the receiving part d. For this reason, as shown by a two-dot chain line in the figure, the front frame door c is placed in a state where the ball storage tray e is full and the game ball x stays in the ball flow passage f on the upstream side of the ball delivery outlet b. When it is opened, the game ball x staying in the ball flow passage f is placed on the protruding portion w of the shutter plate a (see FIG. 11B), and it gets on as the shutter plate a stands. The loaded game ball x spills forward from the ball outlet b (see FIG. 11C).

  The present invention has been made in view of the present situation, and an object of the present invention is to provide a gaming machine in which game balls are unlikely to spill from the ball outlet when the front frame door is opened.

  The present invention has a gaming machine main body provided with a payout device for paying out game balls, a ball delivery port through which the game balls paid out by the payout device can flow forward, and a ball storage tray disposed on the front surface. A front frame door pivotally supported on the front side of the gaming machine main body so as to be able to open one side, and projecting rearward from the front frame door, and being fitted into the ball outlet in a closed state of the front frame door, A ball lead-out receiving portion that receives the game balls paid out by the payout device and leads them to the ball storage tray, and is pivotally supported by a lower edge portion of the ball delivery outlet, and is urged by the urging spring to support the front frame. When the door is open, it is urged and held in an upright position that closes the ball delivery port. When the front frame door is closed, the ball is in elastic contact with the rear edge of the ball lead-out receiving part fitted into the ball delivery port. In a gaming machine provided with a shutter plate held in a tilted position that opens a delivery port, the surface of the shutter plate, A concave elastic contact concave surface portion is provided at the rear edge of the ball lead-out receiving portion to follow it while being elastically contacted by an urging spring when the ball lead-out receiving portion retracts forward with the opening operation of the front frame door. It is a gaming machine characterized by this.

  According to this configuration, the shutter plate can be largely raised with respect to the ball lead-out receiving portion that retracts forward by the opening operation of the front frame door. That is, in the conventional flat shutter plate, as shown in FIG. 11, the upper end portion of the shutter plate is positioned on substantially the same plane as the elastic contact portion of the shutter plate and the ball lead-out receiving portion and the support shaft of the shutter plate. However, the shutter plate according to the present invention is configured so that the concave elastic contact surface portion is brought into elastic contact with the rear edge of the ball lead-out receiving portion when the front frame door is opened. Therefore, the rising angle of the shutter plate can be made larger than that of the flat shutter plate. In the present invention, the “upper end portion of the shutter plate” refers to the most distal portion of the shutter plate farthest from the support shaft, and the “standing angle of the shutter plate” refers to the upper end portion of the shutter plate and the support shaft. The angle between the virtual plane and the horizontal plane.

  Thus, in the present invention, since the standing angle of the shutter plate in the opening operation of the front frame door is larger than that of the conventional configuration, the upper end portion of the shutter plate is positioned closer to the front than the conventional configuration. The protrusion width from which the shutter plate protrudes rearward of the ball lead-out receiving portion is reduced. Therefore, in the present invention, the game ball upstream of the ball delivery port is difficult to get on the shutter plate during the opening operation of the front frame door, and the game ball is difficult to fall off from the ball delivery port.

  Further, in the above configuration, the elastic contact concave surface portion is the first to follow the shutter plate when the shutter plate changes from the tilted position to the standing position as the ball lead-out receiving portion is retracted forward. It is desirable to improve speed. Here, the “following initial speed of the upper end portion of the shutter plate” means the upper end portion of the shutter plate that follows the rear edge of the ball lead-out receiving portion when the ball lead-out receiving portion starts to retract forward from the closed state of the front frame door. The relative speed in the forward direction. “Improving the initial follow-up speed” refers to improving the follow-up initial speed as compared to a flat shutter plate.

  That is, according to such a configuration, when the ball lead-out receiving unit starts to retreat forward from the position in the closed state of the front frame door, the upper end portion of the shutter plate immediately starts to turn forward, and the ball lead-out receiving unit It follows the trailing edge. As described above, as shown in FIG. 11B, the shutter plate having the conventional configuration greatly protrudes behind the ball lead-out receiving portion when the front frame door is opened, as shown in FIG. 11B. This is because the forward movement of the upper end of the shutter plate a is slow. Therefore, as in this configuration, when the elastic contact concave surface portion is arranged so that the initial follow-up speed of the upper end portion of the shutter plate is increased, the protruding width of the shutter plate can be reduced, and the upper surface of the shutter plate can be reduced. It is possible to appropriately prevent the game ball from being mounted on. In addition, even when the game ball is not staying upstream of the ball lead-out receiving unit and the game ball is vigorously paid out from the ball flow passage when the front frame door is opened, the game ball Can be reliably stopped on the back side of the shutter plate to prevent the outflow.

  As the initial follow-up speed of the shutter plate, when the shutter plate changes from the tilted position to the standing position as the ball lead-out receiving part moves forward, the rearward protruding width of the shutter plate is always equal to or less than the radius of the game ball. It is desirable that This is because game balls are hardly mounted if the protruding width of the shutter plate is within the range.

  As described above, as a specific configuration for improving the initial follow-up speed of the shutter plate, the shutter plate is moved forward by rotating the sphere lead-out receiving portion substantially horizontally from the closed position of the front frame door. Along with retraction, the elastic contact concave portion is rotated forward and upward while elastically contacting the rear edge of the ball lead-out receiving portion and converted to the standing position. With the rear edge of the ball lead-out receiving part retracted slightly forward from the position in the closed state of the front frame door, the rear lower side of a virtual plane connecting the support shaft of the shutter plate and the upper end portion of the shutter plate A configuration is proposed in which the shutter plate is provided on the surface of the shutter plate so as to be in elastic contact with the rear edge of the ball lead-out receiving portion.

  In such a configuration, immediately after the shutter plate starts to stand up, the elastic contact surface portion comes into elastic contact with the ball lead-out receiving portion, so that the rising angle of the shutter plate is increased by the amount corresponding to the recess of the elastic contact surface portion, and the rising angle is large. The follow-up initial speed can be improved as compared with the flat shutter plate. Usually, immediately after the shutter plate starts standing up, the rear edge of the ball lead-out receiving portion and the portion near the upper end portion of the shutter plate are in elastic contact, so the elastic contact concave portion in the present invention is formed at least in the portion near the upper end portion. It is desirable that Moreover, it is desirable that the dent condition of the elastic contact concave surface portion in the portion near the upper end portion is large. This is because the rising angle of the shutter plate is increased, and the initial follow-up speed of the shutter plate can be further improved.

  As described above, according to the present invention, the shutter plate can be quickly raised during the opening operation of the front frame door, and the protrusion width of the shutter plate protruding rearward of the ball lead-out receiving portion can be reduced. . For this reason, in the gaming machine of the present invention, even when the front frame door is opened in a state where the game ball stays in the upstream side of the ball outlet, the game ball is unlikely to spill from the ball outlet, Restoration work can be performed smoothly.

  As shown in FIG. 6, the shutter plate 40 is obtained by processing a metal plate piece into a sheet metal, and mainly includes a curved plate-shaped shielding portion 62 that closes the ball outlet 34. As shown in FIG. 4, the shielding part 62 has a shape that is slightly smaller in front view than the ball outlet 34, and stands from the lower edge of the ball outlet 34. The game ball is blocked so that it cannot flow out. The upper right part of the shielding part 62 is notched so as to match the shape of the escape part 36 of the ball outlet 34. Further, as shown in FIGS. 5 and 6, the shielding part 62 is curved so that its longitudinal section forms an arc shape, and a concave surface 64 is formed on the entire front surface of the shielding part 62. As will be described later, the concave surface 64 elastically contacts the rear edge of the ball lead-out receiving portion 64 in accordance with the opening operation of the front frame door 6, that is, constitutes the elastic contact concave surface portion 64 in the present invention. It is.

  As shown in FIG. 6, tubular shaft hole portions 63, 63 are disposed on both sides of the lower edge of the shielding portion 62. By inserting the support shaft 41 through the shaft hole portions 63, 63, The shutter plate 40 is rotatably held. Further, as shown in FIG. 5B, the front surface 65 of each shaft hole 63 abuts against the main body frame 5 when the shutter plate 40 is located at the upright position β, so that the shutter plate 40 is in the upright position β. It works to restrict it from turning forward.

  As shown in FIG. 6, the urging spring 42 is a torsion coil spring. The urging spring 42 is externally fitted to the support shaft 41, one end abuts against the back surface of the shutter plate 40, and the other end is the back surface of the mounting bracket 43. , The shutter plate 40 is urged to rotate to the upright position β.

  Below, the conversion aspect of the shutter board | plate 40 accompanying the opening operation | movement of the front frame door 6 is demonstrated.

  FIG. 7A shows a closed state of the front frame door 6. In such a state, the ball lead-out receiving part 50 is fitted into the ball delivery port 34 and closes the inlet of the payout ball discharge path 35. Further, the shutter plate 40 is pushed down by the rear edge 51 of the ball lead-out receiving portion 50 and is held at the tilt position α in a state where the upper end portion 67 is in elastic contact with the rear edge 51 of the ball lead-out receiving portion 50. In such a state, the game ball x paid out from the payout device 31 flows down the ball flow passage 32a, rolls onto the ball lead-out receiving unit 50, and flows out from the ball delivery outlet 34 to the firing ball storage dish 10. Become. Further, when the game balls x are paid out in large quantities and the launch ball storage tray 10 becomes full, and the ball lead-out receiving unit 50 is also filled with the game balls x, as shown in FIG. The game ball x stays at 32a.

  FIGS. 7B to 8E show conversion modes of the shutter plate 40 accompanying the opening operation of the front frame door 6. As shown in FIG. 7B, when the front frame door 6 is slightly opened and the ball lead-out receiving portion 50 advances slightly (about 5 mm), the shutter plate 40 leads the ball toward the upper end side of the elastic contact concave portion 64. The upper end portion 67 of the shutter plate 40 is rotated forward and upward so as to follow the rear edge 51 of the ball lead-out receiving portion 50 while being elastically contacted with the rear edge 51 of the receiving portion 50. . In addition, the diameter of the game ball x in the figure is about 11 mm.

  When the ball lead-out receiving portion 50 further advances from the state of FIG. 7B and retreats forward about 1 cm from the closed state of the front frame door 6, the shutter plate 40 is elastically contacted as shown in FIG. 7C. The concave surface portion 64 is rotated in the standing position β direction while gradually shifting the position where the concave surface portion 64 elastically contacts the rear edge 51 of the ball lead-out receiving portion 50 toward the support shaft 41 side. Then, the upper end portion 67 of the shutter plate 40 rotates forward and upward and protrudes directly above the ball lead-out receiving portion 50. As shown in FIG. 7C, in this state, the game ball x staying in the ball flow passage 32 a is locked on the back side of the upper end portion 67 of the shutter plate 40.

  Then, when the ball lead-out receiving part 50 further advances from the state of FIG. 7C, the shutter plate 40 further rotates in the standing position β direction as shown in FIG. It pivots forward and upward and protrudes directly above the ball lead-out receiving portion 50. Thereby, the inlet 37 of the payout ball discharge path 35 is opened, and the game ball x staying in the ball flow path 32 a flows into the payout ball discharge path 35 and flows out to the surplus ball storage dish 11.

  Furthermore, when the front frame door 6 is opened and the ball lead-out receiving part 50 is completely withdrawn from the ball outlet 34, the shutter plate 40 is rotated to the standing position β as shown in FIG. The ball outlet 43 is closed by the shutter plate 40.

  Thus, when the ball lead-out receiving portion 50 is retracted forward by the opening operation of the front frame door 6, the shutter plate 40 is rotated from the tilted position α to the standing position β and the ball delivery port 43 is blocked. To do.

  Here, in this embodiment, as shown in FIGS. 7 and 8, the standing angle of the shutter plate 40 in the opening operation of the front frame door 6 (the virtual plane connecting the upper end 67 and the support shaft 41 is the horizontal plane. The angle) is larger than that of the flat shutter plate a having the conventional configuration. This is because the elastic contact surface portion 64 is elastically contacted with the rear edge 51 of the ball lead-out receiving portion 50, and therefore the virtual portion connecting the upper end portion 67 of the shutter plate 40 and the support shaft 41 by the amount of the recess of the elastic contact surface portion 64. This is because the plane rotates forward and upward.

  Further, in this embodiment, the elastic contact concave surface portion 64 is formed at least near the upper end portion of the shutter plate 40, and the sphere is derived from the position of the front frame door 6 in the closed state as shown in FIG. When the receiving portion 50 is slightly retracted forward, the elastic contact concave surface portion 64 comes into elastic contact with the rear edge 51 of the ball lead-out receiving portion 50 so that the rising angle of the shutter plate 40 is increased.

  According to such a configuration, the initial follow-up speed of the upper end portion 67 of the shutter plate 40 becomes larger than that in the conventional configuration, and the shutter plate 40 is converted from the tilt position α to the standing position β as shown in FIGS. Until the ball lead-out receiving part 50 is hardly projected.

  Thus, in the pachinko machine 1 according to the present embodiment, when the front frame door 6 is opened, the shutter plate 40 does not protrude into the ball lead-out receiving portion 50, so that the game ball x staying in the ball flow passage 32a is released from the shutter. The game ball x does not fall on the ball outlet 34 without being placed on the plate 40.
