The record player which adopted the belt drive
scheme by 8 pole hysteresis synchronous motor.
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
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.
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.
combination EP adapter by which the belt protective device and the proper
overhang of a new-installation meter are obtained is carried.
jacket carries the free stop hinge.
PC-20 which is man-month type
cartridge is carried in the cartridge.
There was also PL-41DC of
cartridge a non-carrying model.
