Description
 
Belt drive pre Ya announced as a twin arm specification machine of highest-class model PL-41D of those days

8 pole hysteresis synchronous motor is adopted as a motor, eight poles are used from four poles, a rotational frequency is dropped on one half, a speed ratio is made small, and rotation unevenness is decreased. The diameter of the motorized pulley also became twice as many thickness as this, and ±0.3% or less of the rotational frequency precision is realized.
The special suspension of the dual structure by synthetic rubber and a spring is adopted as a join of a motor and a board.

The thing made from polyurethane is adopted as the rubber belt used by a belt drive scheme.
By peculiar manipulation, this belt presses down thickness unevenness to 5/1000mm or less, and is aiming at the modification of a property.

The turntable has adopted the thing of the diameter of 31cm of aluminum alloys which thickened the perimeter.
The honing manipulation of the bearing is carried out, the axis carried out precision polish of the material excellent in wear resistance, and outstanding inertia efficiency is realized.

The S character type pipe arm is adopted as a tone arm, and the stylus-force coordination of a lateral balancer, a magnetic-repulsion type anti skating organization, and a Direct-reading scheme, the arm height adjusting device, etc. are carried.
Moreover, the arm of two flat knots has adopted the panel switching system in order to make all arms a mounting possible. This panel fraction serves as a fixed scheme with four screws.

The plug-in type MC transformer storage part is carried, and MC type cartridge can be easily used by inserting optional MC transformers (PP-402 etc.) in the exclusive space of an on-board.

The indicator combination EP adapter by which the belt protective device and the proper overhang of a new-installation meter are obtained is attached, only by uniting with the numerical character which had the needle point minced on a center shaft, a proper overhang is obtained and the minimum value of a tracking error can be chosen easily.

The free stop hinge is carried in the book jacket.

PC-20 which is man-month type cartridge is carried in the cartridge.

The cartridge table lamp which can be installed to three, and the accessories storage part are prepared.
