Commentary
A tape deck with Oatley berths.
By sticking sensing foils on the tape end, it is possible to play Oatley bathe in both left and right directions.
In order to support low-noise tapes, a tape select switch is adopted. By switching the switch, both conventional tapes and low-noise tapes can be recorded with good sound quality.
The pinch roller operates using an electromagnetic solenoid system, and an auto stopper works when the tape performance is finished. The pinch roller is released as soon as the motor power is turned off.
In addition, simply pressing the Play button keeps the mechanism in the standby state, and the pinch roller works only after the power is turned on. Therefore, it is possible to record while listening using the time switch.
It uses a dual capstan system with two flywheels for right and left running. It reacts quickly to the reverse running of the tape, so it does not interfere with performance.
A belt drive and two flywheels also improve the wow and flutter.
It uses the band brake that is used in commercial and high-grade machines. It operates smoothly and reliably even in sudden stop operation and does not damage the tape.
In order to prevent sudden tension from being applied to the tape, we have adopted a friction slip type reel stand that reduces the tension when a certain amount of force is applied to the tape.
Equipped with a pause mechanism that allows the tape to stop running temporarily even during recording and playback.
A hysteresis synchronous motor is used for the motor, and smooth rotation operation and fluctuation of tape speed due to fluctuation of power supply voltage is suppressed.
