7.3.2 MECHANISM DESCRIPTIONS
- Loading Operation (when a 12 cm disc is used)
1. Insert a 12 cm disc (the sensor turns on the motor
revolution).
2. The disc pushes the Lock Lever in, thereby resetting
the lock currently applied to the Centering Arms.
3. The disc further pushes the Centering Arms in.
4. The right side and left side arms are engaged to per-
form centering of the disc.
5. The disc pushes the Disc Detection Arm in, thereby
pushing the Disc Detection Lever forward.
6. Clamping action retracts the Disc Detection Lever
toward forward side, thereby rotating the Relief Arm.
7. The Relief Arm further pushes the Centering Arm in,
thus detaching it from the disc.
- Loading Operation (when a 8 cm disc is used)
1. Insert an 8 cm disc (the sensor turns on the motor
revolution).
2. The disc does not contact against the Lock Lever,
thus centering of the disc is performed by the
Centering Arm being locked.
3. When the right side slot is used, the lock currently
applied to the Centering Arm remains turned on
even if the disc may touch the Lock Lever because
the disc leaves the lever before it reaches the
Centering Arm.
4. Succeeding procedures are the same as that for 12
cm discs.
- Clamping Operation
1. Insert a disc.
2. The Detection Arm pushed forward by the Detection
Lever turns on rotation of the Jump In Rack.
3. The Jump In Rack then engages with the Two Step
Gear and moves toward right.
4. At the same time, the Mode Selector Lever connect-
ed to the Jump In Rack starts moving toward right,
thereby rotating the Lock Arm and resetting the
mechanical lock. The Clamp Up Arm too is rotated
by the above action and, thus, the Clamp Up Arm
now being lifted by shape of the cam of the Clamp
Arm is lowered.
And, the Guide Arm is also moved down because of
shape of the cam of the Mode Selector Lever.
5. By use of the cam shape, the Jump In Rack being
moved toward right retracts the Disc Detection Lever
in forward direction, thereby turning on rotation of
the Relief Arm.
