Description
@
The record player developed as a player system which demonstrates the performance of the cartridge of its company.

The gyroscope poise turntable is adopted as a turntable.
By the gyroscope poise scheme, the turntable is floated by adopting the magnetic suspension using a magnetic repulsion, and the bearing and the spring are eliminated.

The fixed magnet which constitutes the gyroscope poise is hung by the spring from the chassis. The tone arm is attached to the end of the T type metals bar supporting this magnet, and the oscillation from the outside is suppressed by adopting the scheme which a two-step structure hangs.

The uni-poise tone arm is adopted as a tone arm part.
This arm has adopted theoretically the one-point supporting which is a low friction most. Moreover, the whole perimeter of a bearing part has solved torsion of the longitudinal balance made into the difficulty of this scheme by becoming the balancer calculated beforehand.

XUV/4500Q is adopted as a cartridge FA145J, and XV-15/1200E is adopted as FA112J.
The matching of an arm and a cartridge is calculated in the design cycle, and also one all are adjusted at a time at the workshop.

Controls are only three kinds, 2 speed change, ON/OFF of a motor, and a queue control.
Moreover, a stylus-force coordination can be performed by the slide wait on a linear-line arm, and an anti skate can be adjusted with the tick mark of a bearing basement.

In order to ease the burden placed on an axis, the structure of adsorbing lightly with a magnet while the arm rest locked ahead of an arm was eliminated and had been made balancing is adopted.

A book jacket can be removed.
