  When installing a pachinko machine in a gaming hall, the outer frame and the front frame constituting the gaming machine main body are separated, and the outer frame is attached to the island, and then the front frame is attached to the outer frame via a hinge. For this reason, when installing pachinko machines, the front frame removed from the outer frame must be stood somewhere once. However, with conventional pachinko machines, the rear frame of the game ball tank is placed behind the fall of the front frame. There is a problem that the wall portion is easily damaged.

  In other words, the ball tank is made of a synthetic resin integrally provided with a peripheral wall and a bottom wall. The ball tank has a shape in which the upper side is opened to facilitate the supply of game balls, and is mounted on the upper rear side of the front frame. Therefore, when the front frame falls down to the back side, the rear wall side of the peripheral wall of the ball tank may come into contact with the floor or an obstacle on the floor side and be damaged.

  In addition, since a ball tank in which a large number of game balls flow without interruption generates static electricity, conductive resin tends to be used for the ball tank to prevent the generation of static electricity. The tank has a drawback that it has a lower impact resistance than those using an insulating resin such as a PC, and is relatively easily damaged by an impact at the time of falling.

  If the rear wall of the ball tank is damaged, if the ball tank and the tank rail are integrated, the entire ball tank including the tank rail must be replaced, which is very wasteful in terms of materials. Will occur. In addition, because there are multiple types of ball breakers that prevent game balls from overlapping on the tank rail side, replacement of damaged ball tanks is complicated and time consuming. The attached mechanism will also be discarded.

Other configurations are the same as those of the first embodiment.

  Although the rear wall 87b of the upstream part of the tank rail 52 is lower than the rear wall 57 of the ball tank 51, the rear wall 87b has a sufficient height as compared with the downstream part, so that when the front frame 4 falls to the back side, There is a risk that the upper part may be damaged by contact with an obstacle. Therefore, if the detachable wall 64 is provided so as to extend from the ball tank 51 to the rear walls 57 and 87b of the tank rail 52, it is possible to easily cope with the breakage of the rear wall 87b of the tank rail 52. Can do.

  17 and 18 illustrate a fourth embodiment of the present invention. In this embodiment, the tank rail 52 is integrally disposed on the front side of the ball tank 51, and the front wall 56 of the ball tank 51 and the front wall 87 a of the tank rail 52 are on the back surface of the back plate portion 4 a of the front frame 4. It is substantially linear in the left-right direction along. The tank body 63 is provided with an opening 62 extending from the rear wall 57 to the rear side of the left and right side walls 58 and 59 and the rear side of the bottom wall 60, and the opening 62 is closed by the detachable wall 64. ing. The detachable wall 64 has the entire rear wall 57, side wall portions 64a and 64b bent from the left and right sides to the front side, and a bottom wall portion 64c bent from the lower end side to the front side. Other configurations are substantially the same as those of the first embodiment.

  In this way, when the back plate portion 4a of the front frame 4 is flat, the tank rail 52 is disposed on the front side of the ball tank 51. In this case as well, the rear portions of the left and right side walls 58, 59 from the rear wall 57 are arranged. By providing the open part 62 that extends over and covering the open part 62 with the detachable wall 64, the same effect as in the first embodiment can be obtained. Further, by providing the side wall portions 64 a and 64 b and the bottom wall portion 64 c integrally with the detachable wall 64, it is possible to deal with damage to a wide area on the rear side of the ball tank 51. The detachable wall 64 may be provided with a ball receiving portion 54 as indicated by a two-dot chain line.

  As mentioned above, although each embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the embodiment, the tank main body 63 and the tank rail 52 of the ball tank 51 are illustrated as an integral unit, but the tank main body 63 may be detachably coupled to the tank main body 63.

  The detachable wall 64 is only required to be detachably attached to the open portion 62 side of the tank body 63, and its coupling structure is not limited to the embodiment, but the coupling portion is provided with a fitting / detaching type, other engaging means, and the like. It is desirable to fix the mounting portion at a position away from the engaging means through the ball receiving portion 54, the cover portion 55, and the like to the fixing portion of the tank main body 63 with a fixing tool. The ball receiving portion 54 and the cover portion 55 may be omitted.

  The opening 62 and the detachable wall 64 are preferably sized to extend over substantially the entire length of the rear wall 57 of the ball tank 51 in the left-right direction. If there is a portion that is difficult to break even when the front frame 4 falls due to the reason, the opening 62 and the detachable wall 64 may be provided in a range excluding the portion.

  The opening 62 and the detachable wall 64 may be provided at least on the upper side of the rear wall 57, such as provided in the upper half of the rear wall 57 of the ball tank 51. The ball receiving portion 54 protrudes from the detachable wall 64 onto the tank main body 63, but may be provided across the tank main body 63 and the upstream portion of the tank rail 52. The cover portion 55 is for preventing the game ball from spilling on the tank rail 52 side and / or the upstream side of the tank rail 52 of the ball tank 51, but the ball receiving portion 54 is on the tank body 63. Alternatively, the cover portion 55 may be disposed on the upper side of the upstream portion of the tank rail 52. The number of inclined passages of the tank rail 52 may be one, or three or more.

  In the embodiment, the tank main body 63 and the tank rail 52 are directly mounted on the back side of the front frame 4, but they may be mounted indirectly via other members. For example, a game board mounting frame 16 is provided at the upper back of the front frame 4, and after the game board 6 is fitted into the game board mounting frame 16 from the back side, the openable open / close mechanism plate is closed to fix the game board 6. In the case of such a pachinko machine, the tank body 63 and the tank rail 52 may be mounted on the upper part of the back side of the back mechanism plate.

  The tank main body 63 and the tank rail 52 are preferably made of a conductive resin, and the removable wall 64 is preferably made of an insulating resin. However, the tank main body 63, the tank rail 52, and the removable wall 64 are made of a conductive resin and an insulating resin. Any of these may be used. In the embodiment, a pachinko machine is illustrated, but the present invention can be similarly applied to various ball game machines such as an arrange ball machine and a sparrow ball machine.
