Description

  The present invention relates to a pachinko machine that uses a game ball to play a game, and more particularly to a pachinko machine in which a receiving tray for receiving a game ball is provided on a front door.

  In general, a pachinko machine has a vertical rectangular machine frame installed in an island facility of a game arcade, a main body frame that is pivotally supported by a hinge mechanism with respect to this machine frame, and a main body frame. It has a game board housed inside and a front door pivotally supported on the front of the main body frame via another hinge mechanism, and the game board can be visually observed in the opening formed in the front door. Possible transparent plates are attached. On the back side of the main body frame, there are a storage tank for storing game balls supplied from the island facility, a game ball payout device for paying out game balls stored in the storage tank, and various controls for games. The control board is provided. Moreover, the saucer which opened the upper surface is provided in the front side of the front door, and this saucer protrudes ahead in the position below a transparent plate. The receiving tray is formed with an intake port for receiving the game balls paid out from the game ball payout device, and a supply port for supplying the game balls in the tray toward the launching device. A game ball is launched into the game area.

  In such a pachinko machine, the number of game balls that can be obtained at the time of a big hit has been increasing in recent years, and accordingly, there is a demand for an increase in the capacity of the tray. Therefore, conventionally, a pachinko machine has been proposed in which the back plate of the saucer is partially recessed toward the back side to form an extended portion, and the storage space for the game ball is expanded by the addition of this extended portion ( For example, see Patent Document 1). In such a conventional pachinko machine, the front door is composed of an upper door and a lower door divided into upper and lower parts, and these upper door and lower door can be opened and closed to the main body frame via separate hinge mechanisms, respectively. It is pivotally supported. A transparent plate made of laminated glass or the like is supported on the upper door, and the tray is provided so as to protrude forward from the base member of the lower door. And by extending the extension part of the saucer on the lower surface of the upper door in the closed state of the lower door, it is possible to realize a large capacity while suppressing the forward projection amount of the saucer.

And the intake port 27 is provided in the back surface 26e of the expansion part 26a, and the bottom surface which slides the game ball discharged | emitted from the intake port 27 becomes the inclination part 26b which inclines toward diagonally forward, This inclination The portion 25b is smoothly continuous with the bottom surface 25b of the dish body 25.

  As shown in FIG. 5, a part of the base member 24 is formed in a substantially U-shaped cross section like the cross-sectional shape of the extended portion 26 a so as to overlap with the rear side of the back plate 26. The U-shaped portion can be placed in a state of being opposed to the lower surface 4c of the outer peripheral holding frame 4b (transparent plate 4) from the lower surface of the rising surface 24e overlapping the rear side of the upper back plate surface 26c of the back plate 26. The mounting portion 24a that is bent so as to be in a horizontal plane, and the transparent plate 4 is bent so as to be vertical from the rear end of the surface of the mounting portion 24a so as to face the rear side of the back surface 26e of the expansion portion 26a. A vertical plane hanging part 24b extending downward substantially in the same plane as the rear surface of the (rear plate 4g), and bent so as to protrude forward from the lower end of the surface of the hanging part 24b, facing the lower side of the inclined part 26b. And an inclined surface-like projecting portion 24c.

  The back surface 24b ′ of the drooping portion 24b is located in front of the above-described game ball launching trajectory M, and obliquely upward between the outer guide rail 8b and the inner guide rail 8c, as shown in FIGS. It is positioned so as to be the back surface 24b ′ of the hanging portion 24b along the left side surface of the game ball Z to be launched. In addition, an intake port 27 is provided on the back surface 24 b ′ of the hanging part 24 b, and the intake port 27 communicates with the intake port 27 provided on the back surface 26 e of the back plate 26.

In addition, a vertical plane-like launch side surface 2b ′ along the right side surface of the game ball Z that is launched obliquely upward in the installation portion 2b is provided so as to face the back surface 24b ′ at a predetermined interval, and thereby the launch trajectory M A front and rear space is formed. Further, the protruding width Y protruding rearward from the surface portion of the base member back surface 24 f shown in FIG. 2 is substantially the same as the protruding width related to the installation of the rectifier 17. Further, the protruding portion 24 c of the base member 24 is located so as to cover the upper surface of the protruding rectifier 17. Then, as shown by a two-dot chain line in FIG. 5, the game ball Z is discharged from the outlet 17 a of the rectifier 17 toward the standby position T.

  Further, as shown in FIG. 2, the mounting portion 24a has a thin plate-like extension that enables a mounting state facing the lower surface 4c from the middle position in the left-right direction toward the left side surface of the outer peripheral holding frame 4b. A protrusion 24g is provided. Thus, the base member 24 of the front door 3 has a portion in which the mounting portion 24a, the hanging portion 24b, and the protruding portion 24c are continued in a U-shape, and this portion is the launch trajectory M of the game ball described above. The upper surface 26f, the mounting portion 24a, and the rear surface 26e of the extended portion 26a of the substantially U-shaped cross section of the rear plate 26 are projected to the rear position from the upper back plate surface 26c (rising surface 24e) to a position that does not hinder the movement. And the drooping portion 24b, the inclined portion (bottom surface) 26b, and the protruding portion 24c are overlapped, so that the load of the heavy transparent plate 4 is bent into the U-shape of the extended portion 26a of the back plate 26 and the base member 24. It is received by the surface part. Therefore, the strength of the receiving portion in attaching the transparent plate 4 to the front door 3 can be ensured after increasing the capacity of the upper tray 13 by the extended portion 26 a of the back plate 26.

  Further, at least a metal plate (iron plate) 29 that covers the entire area of the back surface 26e of the extended portion 26a of the back plate 26 and the hanging portion 24b of the base member 24 so as to be substantially the same shape as the surface shape. This metal plate 29 prevents an illegal act called “drilling goto”. That is, in the present embodiment example, since the back plate 26 and the base member 24 are both molded products made of synthetic resin, the metal plate 29 is interposed between the back surface 26e of the extended portion 26a and the hanging portion 24b. Otherwise, it is possible to make holes relatively easily from the front of the pachinko machine P to the back surface 26e and the hanging part 24b of the extension part 26a. It is possible to prevent fraudulent acts such as inserting the like and releasing the locking of the front door 3 in advance.

  As described above, the pachinko machine P according to the present embodiment is an upper stage from the base member 24 that constitutes a lower part than at least the opening 3a of the integrated door type front door 3 that is pivotally supported with respect to the main body frame 2. The tray 13 (the plate body 25, the back plate 26) is provided so as to protrude, and the back plate 26 of the upper tray 13 is partially within the same plane as the back of the rear plate 4g, partly from the upper back plate surface 26c. Therefore, the space for storing game balls in the upper tray 13 can be expanded. The base member 24 of the front door 3 bends from the rising surface 24e and is placed above the upper tray 13 and held on the back side of the opening 3a. 26a is bent from the mounting portion 24a so as to face the back surface 26e, and extends downward in substantially the same plane as the back surface of the transparent plate 4 (rear plate 4g), and forward from the lower end of the drooping portion 24b. Since it has a protruding portion 24c that protrudes by bending and faces the inclined portion 26b on the bottom surface of the extended portion 26a, the mounting portion 24a, the hanging portion 24b, and the protruding portion 24c are transparent by a continuous U-shape. The loading side surface 2 is formed so that the load of the plate 4 is received and protrudes rearward to a position that does not obstruct the above-mentioned game ball launch trajectory M from the rising surface 24e to form the game ball launch trajectory M. 'And thereby so as to face, it is possible to increase the capacity of the upper pan 13 while ensuring the strength of the receiving portion in the mounting of the front door 3 of the transparent plate 4.

  In the above-described embodiment, the bottom surface of the upper tray 13 is configured by connecting the bottom surface 25b of the plate body 25 and the inclined portion 25b of the back plate 26. However, the bottom surface 25b of the plate body 25 is extended to the extended portion 26a. It is also possible to extend so as to overlap with the bottom surface 26e of the base plate to form a seamless inclined portion.

  In the above embodiment, the metal plate 29 is interposed between the extended portion 26 a of the back plate 26 and the hanging portion 24 b of the base member 24. It can also be provided on the side (so as to cover the entire area of the back surface 24b '). Further, when the back surface 24b ′ or the metal plate 29 of the hanging portion 24 is located in front of the game ball launch trajectory M, the back surface 24b ′ or the metal plate 29 may come into contact with the launched game ball Z. The back surface 24b ′ or the metal plate 29 may be covered with a cover member or the like for protection. Alternatively, as another embodiment, a metal plate having a substantially U-shaped cross section between the upper surface 26f and the mounting portion 24a, the back surface 26e and the hanging portion 24b, and the inclined portion (bottom surface) 26b and the protruding portion 24c ( It is preferable to provide the (steel plate) 29 because the strength of the receiving portion described above can be further increased and fraud can be more difficult to be performed.

  In the above embodiment, the pachinko machine P provided with the upper tray 13 and the lower tray 14 on the front surface of the front door 3 is described as an example. However, the tray targeted by the present invention is the upper tray 13, and the lower tray The tray 14 can be omitted as necessary.
