Document 2 and Patent Document 3).
[0003]
Hereinafter, a conventional video and audio reproduction apparatus will be briefly described with
reference to the drawings.
[0004]
FIG. 9 is a perspective view showing the configuration of a conventional video and audio
reproduction apparatus.
The apparatus main body 101 has a disc cover 102, and a reproducing means 103 for mounting
the disc and reproducing the image information from the disc by operation of a switch after
closing the disc.
Reference numeral 104 denotes a monitor unit for visualizing image information from the disc,
which is rotatably held by the hinge unit 105 of the apparatus main body 101, can be folded and
stored, and has excellent portability.
The electrical connection between the apparatus main body 101 and the monitor unit 104 is
performed by a flexible printed circuit (hereinafter referred to as FPC), a flexible flat cable
(hereinafter referred to as FFC), and the like (not shown). .
[0005]
Reference numeral 106 denotes a speaker provided at the lower part of the monitor unit 104,
which acoustically outputs audio information reproduced from the disc. In addition, a battery
(not shown) can be attached to the back surface, and power can also be supplied from there. A
