Abstract: An air conditioning structure for an electrical appliance, which is capable of air-cooling at least one heat-generating electrical component part in a housing of the electrical appliance while suppressing leakage of operation noise from an air intake fan to the outside, and also capable of achieving a muffling effect and even enhancing the rigidity of the front part of the housing by the front part being constructed of a double structure. The housing accommodates at least one electrical component part group. In the housing, a double plate assembly has a double structure and is comprised of a front plate and a rear plate. The housing has a rear plate provided with two windows and two exhaust fans, which form an exhaust section. The front plate is formed therein with two outer air intake openings, while the rear plate is formed therein with an inner air intake opening.

Abstract: To provide a disk supporting apparatus, a disk holding apparatus and a disk apparatus whose planar dimension is minimized, and which can be manufactured simply and inexpensively. A plurality of supporting portions 44 inclines with respect to a top portion 46 as a vertex. A tray 26 is formed into a substantially triangular pyramid (three-dimensional) configuration, and a planar dimension of the tray 26 can be smaller than that of a conventional turntable. Accordingly, a plurality of disks can be mounted on the tray 26. The supporting portion 44 of the tray 26 can be placed in parallel to a door leaf without a slide mechanism that has conventionally been used for sliding a tray. Accordingly, a desired disk can be attached/detached merely by rotating and driving the tray 26, and a mechanism disposed at a stereo apparatus is made compact and manufactured inexpensively.
