Description

  The present invention relates to a pachinko machine in which a grounding member for removing static electricity from a game ball is provided in a ball tank that stores a game ball supplied from an island facility of a game hall and discharges it toward a payout device. .

  Pachinko machines are designed to pay out game balls as prize balls when a game ball launched by a player turning a launch lever wins a prize device provided in the game area. Need to refill the ball.

  Accordingly, the supply of game balls to the pachinko machines is generally performed by dropping the game balls from an island facility where the pachinko machines are installed in a ball tank provided on the upper back side of the pachinko machine.

  By the way, the game ball supplied from the island facility to the ball tank is charged by friction in the process of flowing through the flow path in the island facility, and falls to the ball tank in a static state. If such static electricity is discharged near the electronic component of the pachinko machine, the electronic component may malfunction or the electronic component may be broken.

  Therefore, conventionally, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2001-300068) and the like, a pachinko machine provided with a ground sheet metal to which a game ball supplied from an island facility to a ball tank comes into contact has been proposed. ing.

  However, in the pachinko machine described in Patent Document 1 and the like, when a charged game ball falls to the bottom of the ball recess of the ball tank, the game is in a conductive state until it comes into contact with the ground metal plate. The game ball remains charged until it touches the ball. Therefore, the static electricity stored in the game ball may be discharged.

  In order to cope with such a problem, it is conceivable to form the entire bottom of the ball tank with a ground metal plate. However, there is a problem that the manufacturing cost becomes high.

  It is also conceivable to provide a ground metal plate at the falling position of the game ball. However, since the falling position of the game ball differs depending on the island facility, it is not realistic to provide a ground sheet metal at a specific position.

JP 2001-300068 A

  Here, the present invention has been made in the background as described above, and the problem to be solved is that it is possible to quickly remove the static electricity charged with the game ball supplied from the island facility. It is to provide a pachinko machine having a novel structure.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  In the present invention, the bottom surface of the ball recess formed by opening upward receives the game ball supplied from the island equipment of the game hall, stores the game ball in the ball recess, and the bottom surface is inclined. It is equipped with a ball tank that discharges the game balls stored in the ball recess toward the payout device on the downstream side, and the static electricity charged in the game ball is removed in the ball recess of the ball tank. In a pachinko machine provided with a ground member, the ground member has a ball contact portion disposed on the bottom surface of the ball recess, and a guide projection is provided on one of the ground member and the ball tank, A guide groove is provided on the other of the member and the ball tank, and the guide protrusion engages with the guide groove to be guided to slide the ground member along the bottom surface of the ball receiving recess. It is possible to change the position of the ball contact part. To.

  In such a pachinko machine structured according to the present invention, the ball contact portion of the ground member can be positioned at the fall position of the game ball supplied from the island facility. Thereby, it becomes possible to receive the game ball supplied from the island facility to the ball tank at the ball contact portion of the ground member. As a result, it is possible to quickly remove static electricity from the game ball supplied from the island facility.

  In the present invention, the tank rail for guiding the game ball to the payout device is separately connected to the ball tank so that the game ball stored in the ball tank is supplied to the payout device through the tank rail. It may be. Alternatively, the game balls stored in the ball tank may be directly supplied to the payout device. In other words, the ball tank itself may have a function of aligning game balls to be discharged to the payout device.

  In this case, when the game balls stored in the ball tank are directly supplied to the payout device, a tank region having a bottom surface configured to include a first inclined surface descending from one side to the other in the width direction of the pachinko machine, and the tank A rail region having a bottom surface that includes a second inclined surface that is adjacent to the region on the back side of the pachinko machine and falls in a direction opposite to the first inclined surface; a downstream end of the tank region; and a rail region A connection area that connects the upstream end of the ball tank is formed in the ball recess of the ball tank, and a game ball that has fallen to the bottom surface of the tank area reaches the rail area from the tank area via the connection area. It is desirable to discharge from the downstream end of the region toward the dispensing device.

  In this case, the ball contact portion of the ground member is superimposed on the bottom surface of the tank area, but since the rail area is formed on the back side of the pachinko machine with respect to the tank area, the depth of the pachinko machine in the tank area is The dimension in the direction becomes shorter than the dimension in the depth direction of the pachinko machine in the ball recess. Thereby, it becomes possible to shorten the dimension in the depth direction of the pachinko machine in the ball contact portion of the earth member. As a result, the overall size of the ground member can be reduced.

  In the present invention, the shape of the guide groove is not particularly limited as long as it has a function of guiding the guide protrusion in a specific direction. For example, there is no bottom like a hole. An aspect may be sufficient.

  Furthermore, in the present invention, it is desirable that the ground member has a vertical plate portion that is superposed on a side surface extending in the width direction of the pachinko machine at the ball recess of the ball tank. This eliminates the need to secure a space for forming the guide groove and the guide projection at the ball contact portion of the ground member. As a result, even when the ball contact portion is small, it is possible to secure a large area for receiving the game ball supplied from the island facility in the ball contact portion.

  Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a pachinko machine 10 as an embodiment of the present invention. In the pachinko machine 10, an inner frame 14 as a pachinko machine body is assembled in an openable and detachable manner on the front side of the opening of the outer frame 12 that forms the outline of the machine body. In addition, a game board (not shown) in which a game area (not shown) is formed is detachably assembled to the middle frame 14, and the game area is assembled to the middle frame 14 so that it can be opened and closed. The player can visually recognize through the transparent plate 18 held by the frame 16. Then, when the player rotates the operation lever 22 that is rotatably attached to the operation handle 20 provided in the middle frame 14, the player stores it in the firing ball storage tray 24 provided in the middle frame 14. The game ball is sent to a launching device (not shown) via a ball feed mechanism (not shown) and then launched toward the game area.

  Further, as shown in FIG. 2, a tank unit 26 as a ball tank is provided at the upper rear side of the pachinko machine 10. The game balls stored in the tank unit 26 are paid out by a payout device 28 that is driven by the winning of a game ball to a winning device (not shown) provided in the gaming area. The game balls paid out by the payout device 28 are stored in the launch ball storage tray 24. In FIG. 2, illustration of the game board and the board case disposed on the back side of the game board is omitted.

  The tank unit 26 is made of a hard synthetic resin material such as ABS or PC, and includes a ball recess 30 that opens upward as shown in FIGS. 3 and 4. Yes.

  In addition, a tank region 32 is formed in the ball recess 30 of the present embodiment, and the bottom surface of the tank region 32 is a first inclined surface 34 that descends from one to the other in the width direction of the pachinko machine 10. ing. Thereby, the flow direction of the game ball in the tank region 32 is a direction from one side to the other side in the width direction of the pachinko machine 10.

  Further, an intermediate region 36 as a connection region is formed in the ball recess 30 of the present embodiment on the other side in the width direction of the pachinko machine 10 from the downstream end of the tank region 32. The bottom surface 38 of 36 is an inclined surface that descends in a direction away from the middle frame 14 in the depth direction of the pachinko machine 10. Thereby, the flow-down direction of the game ball in the intermediate region 36 is the direction away from the middle frame 14 in the depth direction of the pachinko machine 10.

  In the present embodiment, the upstream end of the bottom surface 38 of the intermediate region 36 is positioned lower in the vertical direction of the pachinko machine 10 than the downstream end of the bottom surface (first inclined surface 34) of the tank region 32. That is, a step 40 is formed between the tank region 32 and the intermediate region 36. As a result, after the game ball flowing down the tank region 32 enters the intermediate region 36, the side surface 42 of the intermediate region 36, that is, the side surface located on the other side in the width direction of the pachinko machine 10 in the ball recess 30. It is possible to advantageously avoid the collision and bouncing back and returning to the tank region 32.

  Furthermore, the rail area | region 44 is formed in the spherical recess 30 of this embodiment. The rail region 44 is formed so as to extend from the other side in the width direction of the pachinko machine 10 to the one side on the back side of the pachinko machine 10 with respect to the intermediate region 36. Here, since the end on the back side of the pachinko machine 10 in the intermediate area 36 and the end on the back side of the pachinko machine 10 in the tank area 32 are at the same position in the depth direction of the pachinko machine 10, the rail area 44 is in the tank. The area 32 is positioned adjacent to the back side of the pachinko machine 10.

  Further, the bottom surface of the rail region 44 is a second inclined surface 46 that descends from the other side in the width direction of the middle frame 14 to one side. Thereby, the flow direction of the game ball in the rail region 44 is set to a direction from the other side in the width direction of the pachinko machine 10 to one side, that is, a direction opposite to the flow direction of the game ball in the tank region 32. .

  Incidentally, the downstream end of the rail region 44 does not have to be at the same position in the width direction of the pachinko machine 10 as the upstream end of the tank region 32, but the downstream end of the rail region 44 is pachinko to the upstream end of the tank region 32. It is desirable to be located on one side in the width direction rather than on the other side in the width direction of the machine 10. As a result, it is possible to ensure a large length of the game ball in the flow direction in the rail region 44. Incidentally, in the present embodiment, the downstream end of the rail region 44 is positioned on one side in the width direction of the pachinko machine 10 with respect to the upstream end of the tank region 32, and the flow distance of the game ball in the rail region 44 becomes longer. ing.

  In the present embodiment, the upstream end of the bottom surface (second inclined surface 46) of the rail region 44 is positioned below the downstream end of the bottom surface 38 of the intermediate region 36 in the vertical direction of the pachinko machine 10. That is, a step 48 is formed between the intermediate region 36 and the rail region 44. As a result, the game ball that has flowed into the rail region 44 from the intermediate region 36 collides with the side surface 47 of the rail region 44, that is, the side surface 47 on the back side of the pachinko machine 10 in the ball recess 30, and rebounds. It is possible to advantageously avoid returning to step (b).

  Further, the bottom surface of the tank region 32 is a first inclined surface 34 that goes down from one side in the width direction of the pachinko machine 10, and the second slope that the bottom surface of the rail region 44 goes down from the other side in the width direction of the pachinko machine 10. Because of the surface 46, a step 49 is formed at the boundary between the tank region 32 and the rail region 44. Thereby, the game balls flowing down the rail area 44 are prevented from flowing into the tank area 32.

  Furthermore, a dispensing device 28 is connected to the downstream end of the rail region 44. Thereby, the game ball supplied from the island facility of the game hall falls to the bottom surface of the tank area 32 and then reaches the rail area 44 via the intermediate area 36 from the tank area 32, and reaches the downstream end of the rail area 44. Is discharged to the dispensing device 28. Since the payout device 28 has a conventionally known structure including a prize ball payout motor, a detailed description thereof will be omitted.

  In addition, the rail region 44 is bent again in order to extend in the width direction of the pachinko machine 10 after being bent toward the back side of the pachinko machine 10 on the near side of the upstream end of the tank region 32 in the flow direction of the game ball. As a result, in the vicinity of the upstream end of the tank area 32, the rail area 44 is positioned away from the tank area 32 to the back side of the pachinko machine 10. As a result, a fixed wall portion 50 erected from the bottom surface of the ball receiving recess 30 is positioned near the upstream end of the tank region 32 in a state sandwiched between the rail region 44 and the tank region 32. That is, the fixed wall portion 50 extends from the upstream end in the tank region 32 to the downstream side at the boundary portion between the tank region 32 and the rail region 44. The fixed wall portion 50 partitions the tank region 32 and the rail region 44 in the vicinity of the upstream end of the tank region 32.

  Further, a separation wall 52 for dividing the game balls flowing down the rail region 44 into two rows from the near side to the downstream end of the rail region 44 before the first bend in the flow direction of the game balls in the rail region 44. Is erected on the bottom surface of the rail region 44. Thereby, supply of the game ball to the payout device 28 is performed smoothly.

  Still further, in the area where the separation wall 52 is erected in the rail area 44 (hereinafter referred to as a game ball separation area), ball leveling members 54 and 56 are disposed. The ball leveling members 54 and 56 are respectively arranged in a suspended state with respect to a support shaft extending in the depth direction of the pachinko machine 10 and are swingable with respect to the support shaft. Here, the ball leveling member 54 is disposed in an intermediate portion in the flow-down direction of the game ball in one of the two flow paths formed in the game ball separation region, and the ball leveling member 56 is separated from the game ball separation. It is arrange | positioned at the other downstream end of the two flow paths formed in the area. That is, the game balls flowing down the rail region 44 are subjected to the ball leveling action by the ball leveling members 54 and 56 in the game ball separation region formed in the middle portion of the game ball in the flow direction in the rail region 44. It has become. As a result, the game balls stacked in the rail region 44 are leveled by the ball leveling members 54 and 56.

  The tank region 32 is provided with a ground member 58. The ground member 58 is formed of a metal material and includes a bottom plate portion 60 as a spherical contact portion that is superimposed on the bottom surface (first inclined surface 34) of the tank region 32.

  Therefore, in this embodiment, the dimension in the depth direction of the pachinko machine 10 in the bottom plate portion 60 is substantially the same as the dimension in the depth direction of the pachinko machine 10 on the bottom surface (first inclined surface 34) of the tank region 32. ing. Thus, the position where the ground member 58 is disposed on the bottom surface (first inclined surface 34) of the tank region 32 is covered with the bottom plate portion 60 over the entire depth direction of the pachinko machine 10.

  Moreover, in this embodiment, the thickness dimension of the bottom plate part 60 is made sufficiently smaller than the radius of the game ball. As a result, the game ball located on the upstream side of the ground member 58 can easily get over the bottom plate portion 60 in a state where the game balls are stored in the full ball recess 30. As a result, it is possible to ensure a large volume of the ball recess 30.

  Furthermore, the ground member 58 of the present embodiment is integrally formed with a vertical plate portion 62 that protrudes in one thickness direction of the bottom plate portion 60 at the end of the bottom plate portion 60 on the inner frame 14 side. As a result, the ground member 58 is configured such that the vertical plate 62 is the side surface 64 on the side of the middle frame 14 in the tank region 32 in a state where the bottom plate portion 60 is superimposed on the bottom surface (first inclined surface 34) of the tank region 32. That is, the pachinko machine 10 is superposed on the side surface 64 extending in the width direction.

  In the present embodiment, a guide hole 66 as a guide groove is formed in the vertical plate portion 62. As described above, the guide protrusion 68 provided on the side surface 64 on the inner frame 14 side of the tank region 32 in a state where the vertical plate portion 62 is superimposed on the side surface 64 on the inner frame 14 side of the tank region 32, It can be positioned in a guide hole 66 formed in the vertical plate portion 62. As a result, the ground member 58 is slidable in the width direction of the pachinko machine 10 along the bottom surface (first inclined surface 34) of the tank region 32 by the engaging action of the guide protrusion 68 and the guide hole 66. As is clear from this, in this embodiment, the guide protrusion 68 and the guide hole 66 constitute a guide mechanism for the ground member 58.

  In the present embodiment, the sliding displacement of the ground member 58 in the width direction of the pachinko machine 10 is regulated by the guide protrusion 68 coming into contact with the inner peripheral surface of the guide hole 66.

  Further, in the present embodiment, the partition plate portion 72 is provided so as to protrude in the thickness direction of the bottom plate portion 60 at the end of the bottom plate portion 60 on the back side of the pachinko machine 10. The partition plate portion 72 is overlapped with the side surface of the fixed wall portion 50 from the side of the middle frame 14 in a state where the bottom plate portion 60 is overlapped with the bottom surface (first inclined surface 34) of the tank region 32. When the ground member 58 is slid and displaced, the partition plate portion 72 is slid along the fixed wall portion 50.

  The tank unit 26 having such a structure is fixed to the middle frame 14 via the mechanism board 74 by being screwed and fixed to the mechanism board 74 provided on the back side of the middle frame 14. It has become.

  When the pachinko machine 10 having the tank unit 26 as described above is installed in the island facility of the game hall, a hose-like member (not shown) for supplying game balls from the island facility is replaced by the tank unit 26. The tank area 26 can be inserted into the tank unit 26 from above, and a game ball supplied through a hose-like member is received by the bottom surface (first inclined surface 34) of the tank area 32, and a ball recess is received. 30 is stored.

  Here, the ground member 58 disposed in the tank region 32 is slidably displaceable in the width direction of the pachinko machine 10, so that it is superimposed on the bottom surface (first inclined surface 34) of the tank region 32. The bottom plate portion 60 can be moved to the fall position of the game ball supplied from the island facility. As a result, the game ball supplied from the island facility can be brought into contact with the bottom plate portion 60 of the ground member 58 and then flowed down to the intermediate region 36.

  Therefore, in the pachinko machine 10 having the above-described structure, it is possible to quickly remove static electricity from the game ball supplied from the island facility, and malfunction of electronic components due to discharge of static electricity. Such a problem can be advantageously avoided.

  Therefore, in the present embodiment, the game balls stored in the ball recess 30 of the tank unit 26 are directly supplied from the tank unit 26 to the payout device 28, in other words, the ball recess of the tank unit 26. 30 so that the game ball dropped on the bottom surface (first inclined surface 34) of the tank region 32 in 30 reaches the rail region 44 via the intermediate region 36 and is supplied to the dispensing device 28 from the downstream end of the rail region 44. Therefore, the dimension in the depth direction of the pachinko machine 10 in the tank region 32 in which the ground member 58 is disposed can be shortened. Thereby, it becomes possible to shorten the dimension in the depth direction of the pachinko machine 10 in the bottom plate part 60 of the ground member 58. As a result, the overall size of the ground member 58 can be reduced.

  Further, in the present embodiment, since the guide hole 66 is formed in the vertical plate portion 62 of the ground member 58, it is possible to ensure a large contact area with the game ball in the bottom plate portion 60. As a result, even if the bottom plate portion 60 is small, static electricity can be advantageously removed.

  In the present embodiment, since the tank unit 26 is directly fixed to the mechanism panel 74, the bottom of the tank unit 26 can be positioned upward in the vertical direction of the pachinko machine 10. It becomes. That is, it becomes possible to secure a larger space below the tank unit 26. This advantageously realizes an increase in the size of the liquid crystal display device provided in the game area, and makes it difficult to limit the position where the accessory is disposed.

  In particular, in the tank unit 26, the bottom on the tank region 32 side close to the game board can be positioned further upward in the vertical direction of the pachinko machine 10 than the bottom on the rail region 44 side. An arrangement space for the liquid crystal display device and the driving source of the accessory is more advantageously secured.

  As mentioned above, although one Embodiment of this invention was explained in full detail, this is an illustration to the last, Comprising: This invention is not limited at all by the specific description in this Embodiment.

  For example, in the above-described embodiment, guide grooves may be formed on the side surfaces 64 of the tank region 32, while guide protrusions may be formed on the vertical plate portion 62.

  In addition, the present invention is naturally applicable to a spherical tank having a structure in which a tank rail is connected to the bottom of the spherical recess described in Patent Document 1 and the like.

  In addition, although not listed one by one, the present invention can be carried out in a mode to which various changes, modifications, improvements and the like are added based on the knowledge of those skilled in the art. It goes without saying that all are included in the scope of the present invention without departing from the spirit of the present invention.
