Abstract: This display screen turning apparatus (base for a display screen) includes a platelike base member so formed as to receive the load of a display body applied to a display screen support mechanism on a partial region and to warp in a direction opposite to the direction of deflection resulting from the load of the display body with a prescribed amount of warpage when not receiving the load of the display body, and the prescribed amount of warpage is so set that the surface of the base member is substantially flattened when the base member receives the load of the display body applied to the display screen support mechanism.

Abstract: This display screen turning apparatus includes a turntable mounted with a display body and rotatable in a horizontal plane, a base, rotatably holding the turntable, provided with a drawn projecting portion and a floating prevention member so mounted on the projecting portion of the base as to prevent the turntable from upward floating. The floating prevention member has a floating prevention portion provided above a region where the upper surface of the turntable is arranged, a mounting portion for mounting the floating prevention member on the projecting portion and a leg portion provided between the floating prevention portion and the mounting portion for maintaining the base and the floating prevention member at a prescribed interval by coming into contact with the base.

Abstract: A display screen turning apparatus includes a base portion for placing a display screen portion thereon, a driving source and a transmission gear portion arranged inside the base portion, a display screen support member provided with an engaging member and supporting the display screen portion rotatably in a horizontal plane and rotatably with respect to a vertical plane and a rack plate arranged on the base portion and including a rack gear meshed with the transmission gear portion in a horizontal direction. The display screen support member is rotated in an anteroposterior direction with respect to the vertical plane by a prescribed angle with rotation of the engaging member of the display screen support member engaged with the rack plate following reciprocation of the rack plate in the horizontal plane with normal and reverse rotation of the driving source.

Abstract: A display screen turning apparatus includes a base portion for placing a display screen portion thereon, a transmission gear portion for transmitting driving force of a driving source arranged inside the base portion, a display screen support member supporting the display screen portion rotatably in a horizontal plane and a vertical plane, a rack plate arranged on the base portion and including a rack gear meshed with the transmission gear portion in a horizontal direction, and a coupling portion rotatably coupling the rack plate in the horizontal plane with respect to the display screen support member. The display screen support member is rotated in the anteroposterior direction with respect to the vertical plane by a prescribed angle through the coupling portion coupled to the rack plate following reciprocation of the rack plate in the horizontal plane with normal and reverse rotation of the driving source.

Abstract: A disc rotating apparatus includes a turntable for placing thereon a disc such as CD, DVD. The disc is clamped by the turntable and the disc holding frame. The holding frame is formed, at its main body, with an annular groove. The annular groove is circumferentially partitioned by a plurality of partition walls to thereby provide a plurality of accommodating portions. Each of the accommodating portions accommodates therein one or two or more steel balls. Due to rotation of the turntable or disc, each steel ball is displaced within the accommodating portion, thereby correcting for an unbalanced state wherein a center of gravity of the disc is deviated from an axis of a rotary shaft of turntable.
