A full-auto player with an optical display that pursues comfortable operability.

It uses an electronically controlled full-auto mechanism that allows all tone arm operations to be controlled simply by pressing the operation buttons.
The circuit uses a single-chip LSI to realize quick and accurate responses.

It uses an automatic record size detection mechanism by applying an optical system.
In this system, the reflector emits light from obliquely above and guides the light from the turntable seat reflector to the sensor. This light is emitted or blocked depending on the size of the record and changes the output of the sensor. This output is sent to a logic circuit that automatically detects the record size.
Based on the detected record size, the needle down position and rotation speed are automatically determined.

Equipped with a quick response function, it operates while always detecting the condition of the arm lifter and arm. Therefore, it is possible to perform auto operation from any position. Thus, even when the arm is ascending or descending in auto operation, if you indicate the next new operation with the button, it will move immediately to that operation.

For button operation, feather touch type using micro switch is adopted.

Equipped with a muting mechanism to cut noise.

In order to suppress the resonance of the tone arm, a weight case and a butyl rubber damper are added to the structure of the needle pressure knob and main weight, and an anti-resonance filter is adopted. In addition, by expanding the span of the pivot, looseness of the pipe part is eliminated, and high sensitivity is achieved in both vertical and horizontal directions.

The tone arm is driven by a dedicated motor that is independent in both horizontal and vertical directions.

The tone arm is made of stainless steel.

The turntable is driven by a quartz PLL system that controls the number of revolutions of the motor according to the reference signal of the crystal oscillator.
A high-torque DC servo motor with a precisely finished bearing mechanism is used as the drive motor.

Equipped with an optical display that displays the number of revolutions and repeat operation.

The newly developed MM type cartridge is used.

Wooden cabinet is used for the cabinet.
