Description of the Related Art Conventionally, a front mechanism device of a ball game machine such as a pachinko machine, an arrangement ball machine, etc. has a front plate attached to a front side of a game machine main body and below a game board, and a ball is paid out to the front plate. A mouth, a ball feed port, and a ball ejection port are formed, and a hit ball supply tray made of synthetic resin is attached to the front side of the front plate, and a game ball discharged from the ball payout port is a storage section of the hit ball supply tray. The ball is supplied to the ball feeding means from the ball feed port while aligning the game balls in the storage section in a line at the alignment section, and the ball is fed onto the firing rail of the firing means by the ball feeding means. They are sent individually. Further, a speaker is provided in the vicinity of the lower side of the hit ball supply tray, and a sound effect or the like is output from the speaker as the game progresses.

[0003] In recent pachinko machines and the like, when a special right status occurs during a game, a large amount of game balls are paid out from a ball payout means to a hit ball supply tray through a ball payout port. When a large amount of game balls are paid out, the storage amount of the game balls stored in the storage portion of the hit ball supply tray also increases remarkably, and the load of the hit ball supply tray itself due to the load of the game balls increases. Become. Therefore, conventionally, as disclosed in Japanese Utility Model Publication No. 63-5746, a band-shaped outer cover is attached with a space in front of the hit ball supply tray, and the hit ball supply tray and the outer cover are integrally connected.
