Electronic accessory for game machine

Abstract

An electronic accessory for a game machine, adapted to be externally loaded to the game machine into a corresponding connector formed in the game machine body, that includes a housing having slits in a wall thereof for dissipating heat generated by the electronic components of the accessory. To facilitate dissipation of heat within the housing and to the exterior through the slits, a heat radiation frame or assembly is disposed within the housing and includes at least a first heat radiation part disposed between the electronic components and the housing wall. The heat radiation framework of the preferred embodiment is made from a metal material and is generally L-shaped or T-shaped, including a second heat radiation section or part extending generally perpendicular to the first heat radiation part. Heat energy generated by the electronic components of the accessory is transmitted from the electronic components through a thermal sheet to the first heat radiation part from where some heat can be dissipated through the slits in the housing. Additional heat is conducted via the first heat radiation section to the second heat radiation section for dissipation through holes in a protective shield coupled thereto.
