Cable card mounting apparatus and television receiver

Abstract

The present invention provides a cable card mounting apparatus capable of maintaining a temperature that conforms to operating conditions at a high environmental temperature without using a small fan or heat sink. The cable card mounting apparatus comprises a receiver housing and a card mounting section that is positioned outside the receiver housing and provided with a card slot inside the receiver housing. While a connector for a cable card is mounted in the card slot, a main body of the cable card is positioned inside the receiver housing and in parallel with a bottom surface of the receiver housing.
