Description
 
The full-auto player which carries a large-sized insulator, an anti skate organization, etc.

If record size is specified, the full-auto organization in which a performance starts automatically only in an operation of an operation lever is carried.

The capacitor phase shift 16 pole synchronous motor is adopted as an actuator. Since it drives at the about 10X rotational frequency of the rotational frequency of a turntable, there is also little oscillation of a motor and the high SN ratio has been gained.
Moreover, the independent gear motor was adopted as full-auto organizations, and it has prevented an auto organization having an ill effect on a constant-speed rotation.

The anti skate organization of the dial control scheme was carried in the tone arm, sliding of the arm was prevented, and the good trances capacity of a balance has been acquired.
Moreover, a S character type low centroid tone arm is adopted as an arm, and man-month type cartridge is carried.

The precision Direct-reading type of a 0.2g unit of measure is adopted as a balance wait.

Low capacity output code and the same cartridge main unit as the cartridge for compact-disk-4 are adopted, and compact-disk-4 is supported by exchanging the needle point.

The insulator of the special design which used the air suspension together is adopted for the prevention from a howling.

The oil dumping type arm lifter which damages neither the needle point nor the record board is adopted.

The book jacket with an auto hinge which can be detached and attached is adopted.
