It is the full auto player which adopted the linear tracking system.
The arm has adopted the linear tracking system which
carries out straight line movement of the record board top.
By a linear
tracking system, since the tangential adjusting of a sound track is traced
correctly, a tracking error and higher-harmonic-wave distortion can be
decreased. Moreover, since there is no generating of an inside force,
symmetrical contact of the needle point is attained and, on the whole,
improvement in tracking capability can be aimed at.
The stainless steel
wire is adopted as the drive of the move base which fixes a tone arm. This wire
united a thin line 0.05mm in diameter from 49, is performing nylon coating and
has realized the outstanding durability and pliability.
potential difference of two photo-diode outputs of arm back has detected the
The record size automatic detection mechanism in which
the optical system was applied is adopted as detection of record size.
this system, light is glared from the slanting upper part with a reflector,
light is led to a sensor from the reflector for turntable sheets, and the output
of a sensor is changed by glaring / covering light according to the size of a
record. This output is sent to a logic circuit and record size is detected
automatically. Based on the size of the record detected here, a needle descent
position and a rotating speed are determined automatically.
response mechanism is carried, and if an arm directs the next operation with a
button also in /descent during a rise by auto operation, it will shift to the
The feather touch type which uses a microswitch
is adopted as a manual operation button.
EC (electronic control) circuit
is adopted as a full auto mechanism. In order to control complicated operation
correctly, LSI of one chip is adopted as this circuit.
The needle point
protection function is carried, and when there is no record in a turntable, a
tone arm does not descend.
The muting mechanism which cuts a noise is
The instability of the pipe part was abolished by extending the span of the pivot of a tone arm part, and perpendicularity and a horizontal direction have realized high sensitivity.
Stainless steel is adopted as the quality of the material of a tone arm.
OFCu (non-oxygen conducting wire) which gave special covering is used for the
conducting wire in an arm, and head shell conducting wire, and the total
direct-current resistance from head shell to a pin plug is suppressed.
The direct-drive system by the Quartz PLL system which controls the
number of rotations of a motor by the standard signal of a crystal oscillator is
adopted as the drive of a turntable. Moreover, stable rotation is realized by
adopting the high torque DC servo motor of the bearing mechanism finished
Wooden cabinets are adopted as a cabinet.
