SEIKO EPSON Σ 2000
¥1,400,000 (1990 level first half time)

The record prayer which the temple fence person of the temple fence laboratory developed with the cooperation development with the SEIKO Epson. Σ 2000 was announced, it was announced in 1994 as the moderate price type Σ 5000 47 units were sold.
The fact that the close prayer is built up only the complete transmitter without with the goal of, development is advanced with the viewpoint of clarification of the fulcrum, even quite the accurate prayer which the "surface roughness meter" can be said is actualized.

Bearing structure 1.5 MARU, is designed to be the kind of structure which the principal axis which tilts leans to 2 disks, in order for clearance of the bearing to become with 0 always, it operates. Because of this, even the abnormal play due to the thickness of the oil film it has prevented.
The principal axis administers hard chromium plating to the SKS steel, high accuracy is ground, as for contact width of the disk below 1mm, the touch area is decreased to the utmost. Furthermore, by the fact that hardness of the disk barely is dropped, the machined surface of the extent principal axis which is used copies and Signal-noise ratio has improved.
Lower part of the principal axis is designed to be the point structure by the super hard ball, friction being smallest, in order to be transmitted without at the same time wave motion of the turntable being modulated it is designed.

As for the turntable the extrusive material of the brass sufficient annealing processing after doing, is finished by the high accuracy lathe, considers the sound quality and processing of plating and coating etc. is not done. The surface tilts and 1.5 MARU we have become pickpocket bowl form, in order to cancel the inclination of the principal axis completely at the position where the tip of the needle traces it is considered.
In addition, the set where by the fact that the stabilizer is used, you can push to the turntable the record, stabilize is actualized.
Section of the turntable has become uniqueness appropriating where the standing wave is difficult to happen.
As for the principal axis and the turntable, it is not the mere fit and we have unified firmly with the flange connection by 4 these screws, weight has become approximately 8kg.

We adopt static balance system to the tone arm, as for weight of the head are above 300g, make the standard position of the cartridge stabilize. When this structure is used with general static balance system, balance weight above 2kg becomes necessary and inertia of horizontal direction becomes too large and smooth operation is not possible, but with Σ 2000 it utilizes 2 levers, in order to balance at light weight, with the difference of lever ratio, it is devised.
We are designed to be the structure where always contact pressure is imposed unidirectionally in each fulcrum of the arm, smooth operation is actualized.
The stick of the high strength steel is installed in the arm beam, rigidity is raised by the fact that strong compressed stress is applied.

The individual system which uses the core less brush less motor of new development is adopted to drive of the turntable.
The idler turns, while eating into the turntable, due to the fact that the motor turns, turns at the place where most it stabilizes automatically and transmits torque at high efficiency.
