The record player which adopted the belt drive scheme.

The belt drive scheme by 4 pole synchronous motor is adopted as a drive system. Furthermore, careful finish by a mechanized precision processing machine is given to a turntable, and an axis of revolution and a bearing, and the precision is raised to them.
Moreover, it is used for the belt which tells a rotation of a motor, carrying out precision finish of the polyurethane.

S character type pipe arm which can respond to 4ch play or a light stylus-force performance is adopted as a tone arm, and it is now s.
The anti skating organization in which the ideal value which negates an inside force only by having adopted the design which made the centroid low since trances capacity is t Reddened, and also setting a tick mark according to an impression stylus force is acquired is carried.
In addition, organizations, such as oil dumping type arm elevation of a start lever and an interlock, are adopted.

In order to suppress a howling, the cabinet of the dogged structure which took weight and a large mass is adopted.

PC-110 which is man-month type cartridge is carried in the cartridge.

The checker who can perform an overhang coordination in the case of a switching of a cartridge is carried.

The low capacity (loop station connector) code in which 4ch play is possible is adopted.

The free stop hinge stopped at any angles in a hood is adopted.
