The present invention provides an automotive alternator enabling a brush replacement operation to be improved by making a cap covering an opening portion for brush replacement formed in a case insertable to simplify removal and replacement of the cap.A brush holder through which a brush insertion aperture is disposed and into a head portion of which a cover is fitted is disposed inside a case such that an aperture direction of the brush insertion aperture is perpendicular to an axial direction of a shaft, and a brush is disposed so as to be held inside the brush insertion aperture and slide in contact with a slip ring fixed to the shaft. An opening portion for brush replacement is formed in a portion of the case facing the cover, and a cap is insertably mounted to this opening portion.

An auto changer is comprised of holders, a movable stocker, a player, a tray, transfer gears, disc detection system, and other parts. A disc is placed on each of the holders, and is loaded into and removed from stocker using the tray together with the holder. The tray is movable while the player is playing back, so that other discs can be loaded and removed. The holder has two holding levers, which hold a disc onto the holder in order to prevent the disc from moving out of position or falling into the unit. When two discs are accidentally placed on the tray and are being loaded into the stocker, the disc detection system detects the two discs and stops the tray in order to prevent damage to the discs or the unit.
