Cartridge for a game machine
First Claim
1. A cartridge for a game machine, the cartridge being detachably mountable to a game machine having a connector and a grounding terminal in connection with a recess for receiving the cartridge, the cartridge comprising:
- a housing including an upper half and a lower half, the housing having an open end face at which to mount the cartridge to the connector in the game machine;
a substrate accommodated in the housing, the substrate having an external connection terminal exposed through the open end face, a circuit pattern, and a ground electrode;
a semiconductor element mounted on the substrate; and
a shielding element accommodated within the housing, the shielding element covering a substantial portion of at least one principal face of the substrate and being electrically connected to the ground electrode, wherein the housing has an opening in a principal face facing the ground electrode on the substrate and the shielding element to allow the shielding element to be partly exposed through the opening, the shielding element has a shield convex, the shield convex protruding and being exposed through the opening, and when the cartridge is mounted in the recess, the shield convex is electrically connected to the ground electrode through the opening, thereby removing unwanted radiation of electromagnetic waves occurring on the substrate.

Abstract
A cartridge, including a housing, a substrate, a semiconductor element (e.g., a memory), and a shielding element, is detachably mountable to a game machine having a connector and a grounding terminal, and a recess. The substrate within the housing has an external connection terminal exposed through the open end, a circuit pattern, and a ground electrode. The shielding element within the housing substantially covers at least one principal face of the substrate and electrically connected to the ground electrode. The housing has an opening in a principal face facing the ground electrode on the substrate and the shielding element, through which the shielding element is partly exposed. The shielding element has a protruding shield convex exposed through the opening. When the cartridge is mounted in the recess, the shield convex is electrically connected to the ground electrode through the opening to remove unwanted radiation of electromagnetic waves on the substrate.
