Description
 
The direct-drive player developed making full use of the motor technology of a Lo-D.

The 8 pole 24 slot non-commutator DC servo motor which adopted the direct-drive scheme is adopted as an actuator.
Moreover, DC servo mechanism which also controls slight rotation deflection and maintains an exact rotational frequency is carried.

The electronic control scheme is adopted as a velocity change and a rotational frequency fine tune. Moreover, ±3% of rotational frequency fine tune is each rotational frequency independency, and can be carried out with the stroboscope and neon glow lamp which were formed in the perimeter of the turntable.
Moreover, the power switch and the rotational frequency change serve as a one lever scheme.

The arm attachment which adopted the newly developed large-sized insulator and the rubber vibration insulator as the large cabinet of a howling margin as a measure against a howling is suppressing the vibration.

The low centroid S character type stylus-force Direct-reading type static blance type excellent in trances capacity is adopted as a tone arm.
Moreover, to sliding of an arm, the dial type anti skate organization which enables the stable trances is carried.

The same cartridge main unit as the output code of low capacity and the cartridge for compact-disk-4 is adopted, and compact-disk-4 performance is possible only at a switching of the needle point.

Since the fingerplate is made to serve a double purpose, a neon glow lamp case can be supported by applying a little finger, when bringing the needle point to the record board.

The oil dumping type arm lifter is adopted.

The auto hinge which can be detached and attached is adopted as a book jacket.
