Description
@
The belt drive player which realized the precision which was excellent as a finished-product player.

The hysteresis synchronous motor is adopted as a motor and the structure strong against a variation of a voltage or a load intensity is realized.
Moreover, the belt drive scheme by a polyurethane belt is adopted.

There was also player unit processor-unit-41A of only a mechanism without a cabinet.
