It is the full [ with an optical display ] auto player which investigated comfortable operativity.
The electronic-control full
auto mechanism is adopted. Thereby, it is controllable only by pushing a manual
operation button in operation of all the tone arms.
One chip LSI is adopted
as a circuit and the quick exact reaction is realized.
The record size automatic detection mechanism by application of an optical system is adopted.
By this system, light is glared from the slanting upper part with a
reflector, and it has the structure of leading light to a sensor from the
reflector for turntable sheets. According to the size of a record,
irradiation/interception of this light are done, and it changes the output of a
sensor. This output is sent to a logic circuit and record size is detected
Based on this detected record size, a needle descent position
and a rotating speed are determined automatically.
Since it is operating
carrying the quick response function and always detecting the state of an arm
lifter or an arm, it is possible to carry out auto operation from every
position. Thereby, in auto operation, during a rise, also in /descent, if an arm
directs the following new operation with a button, it will shift to the
The feather touch type which uses a microswitch
is adopted as button operation.
The muting mechanism which cuts a noise
In order to suppress a vibration of a tone arm, the weight
case and the anti Resonance filter which added the butyl rubber damper are adopted as the structure by a needle pressure knob and main weight. Moreover, by
extending the span of a pivot, ガタ of the pipe part was lost and perpendicularity
and a horizontal direction have realized high sensitivity.
motor which became independent in the two horizontal/vertical directions is
adopted as the drive of a tone arm.
Stainless steel is adopted as the
quality of the material of a tone arm.
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, the high torque
DC servo motor of the bearing mechanism finished precisely is adopted as a drive
The optical display which displays operation of number of
rotations or a repeat is carried.
Newly developed MM type cartridge is
adopted as a cartridge.
Wooden cabinets are adopted as a cabinet.
