A record player comprises a player cabinet and a slide base supporting a turntable and movably mounted in the player cabinet for movement into and out of the latter. The record player also includes a front door movably supported by the player cabinet for movement between a vertical position in which the front door closes an open front face of the player cabinet and a horizontal position within the player cabinet. When the front door is opened, it is withdrawn back into the player cabinet so that the front door will not interfere with operator's activities to manipulate the record player. The front door may be pivotably supported by swing levers so that the front door can easily be opened and closed without striking a top plate of the player cabinet. The front door may be actuated by a mechanism operatively connected to a substantially central portion of the front door laterally thereof for smoothly actuating the front door without distorting the front door while it is being opened or closed. The slide base may support thereon a slide base drive mechanism for selectively actuating the front door and the slide base in a timed relationship to each other.
