A record player with a turntable mounted for rotation in a substantially fixed horizontal plane on a chassis and a tone arm for reproducing signals recorded on the surface of a record disc which faces upwardly when the disc is rotatably supported on the turntable, is provided with a record turn-over mechanism comprised of a support structure, for example, in the form of lever assemblies, mounted on the chassis for swinging between raised and lowered positions about an axis which extends parallel to a diameter of the turntable and is disposed to one side of the latter, a pair of spaced apart gripping devices directed inwardly towards each other from end portions, respectively, of the support structure and being axially movable between gripping positions at which the gripping devices are engageable with diametrically opposed locations on the periphery of a record disc and released positions, the gripping devices also being turnable relative to the support structure about a common axis parallel with the axis of swinging movement of the support structure, and cams for effecting the swinging movements of the support structure and the axial and turnable movements of the gripping devices through an operating cycle in which the gripping devices are made to engage a record disc on the turntable with the support structure in its lowered position and then the support structure is moved to its raised position for lifting the engaged disc from the turntable, whereupon the gripping devices are turned through 180 DEG for inverting the lifted record disc and the support structure is then returned to its lowered position and the gripping devices are released for freeing the inverted record disc on the turntable.
