Abstract
Abstract A portable case for audio-visual apparatus has a first case portion including a bottom portion and three side walls connected to the bottom to form a substantial portion of a generally rectangular box. There is a second case portion having a front cover and a top cover, and the second case portion covers the remaining space. There is a partition piece formed in the interior or the case which divides the case into two sections. One section contains a TV monitor and the other contains an audio means for developing the signal displayed on the TV monitor. A power source means is mounted in the case near the audio developing means to receive power from an external source, convert the AC power to DC power, and supply DC power to both the TV monitor and audio developing means.
