Abstract
In a combined, small-sized, portable video/still camera system, it is intended to improve the reliability against a rise in internal temperature of the system and improved reliability against vibration, while keeping small the external size of the system. Such compact system includes a PCMCIA hard disk drive capable of being loaded to, and removed from, the image recording/reproducing system. According to the present invention, as set forth hereinabove, a plate or medium formed of a thermally conductive rubber or copper (higher in thermal conductivity than air) is mounted on an encoder LSI package attached to a side of a circuit board opposite to the hard disk mounted side, and such medium is arranged to conduct heat to the system housing formed of aluminum or other material high in thermal conductivity. As a result, the housing is efficiently used as a heat sink. The hard disk is disposed centrally in the interior of the system, and thus an impact or vibration exerted on the exterior of the system is transmitted to the hard disk only through the mounting frame, so that the impact or vibration is relatively diminished. As an additional advantageous arrangement, the LSI package surf…
