Abstract
The present invention relates to a recording and reproducing device including a DVD unit, an HDD unit and a VCR unit and an MPEG board which processes both video/audio signals of the DVD unit and the HDD unit and provides a recording and reproducing device capable of efficiently radiating heat of an MPEG IC mounted on the MPEG board. A plane 20a of an MPEG IC 20 mounted on an MPEG board 12 is contacted with a contacting surface 4b of a bottom face 4a of a chassis 4 and heat generated in the MPEG IC 20 is directly radiated over the bottom face 4a of the chassis 4. Furthermore, a cooling fan 7 is placed at the back of a recording and reproducing device 1 and heat radiated over the bottom face 4a of the chassis 4 is cooled with a cooling wind.
Claims16
A recording and reproducing device comprising:
- a main board provided with a DVD unit and an HDD unit, which controls overall operation of the recording and reproducing device which constitutes the DVD unit and HDD unit and processes analog video/audio signals;
- and
- an MPEG board which processes digital video/audio signals of the DVD unit and the HDD unit,
- wherein a plane of an MPEG IC mounted on the MPEG board is contacted with a bottom face of a chassis of the recording and reproducing device so as to radiate heat generated in the MPEG IC over the bottom face of the chassis.
