1.6 HOW TO REMOVE THE MAJOR PARTS <VHS section>
1.6.1 Disassembly flow chart
This flowchart shows the disassembly procedure for the ex-
terior parts and electrical parts.
Basically, reverse this procedure when assembling them.
However, it is required to remove the common section parts
as far as 1 “Top cover Bracket” and 2 “Front panel assem-
bly” in advance. (See section 1.5.)

<Note 1>
When attaching or removing the FPC, take care not to dis-
connect any of the wires.
<Note 2>
When attaching the FPC, be sure to connect it in the cor-
rect orientation.
<Note 3>
When attaching wires, connect them in the correct orien-
tation.
<Note 4>
• When it is required to remove the screws (S3) retaining the
Mechanism assembly, please refer to the “Procedures for
Lowering the Cassette holder assembly”(See on page 1-5).
• When removing the Mechanism assembly only, unhook the
two spacers connecting it with the Main board assembly with
pliers from the back side of the Main board assembly first,
and then remove the Mechanism assembly.
• When reattaching the Mechanism assembly to the Main
board assembly, take care not to damage the sensors on
the Main board assembly (D3001: LED, Q3002: Start sen-
sor, Q3003: End sensor, S3002: S cassette switch).

Procedures for Lowering the Cassette holder assembly
As the mechanism of this unit is integrated with the Housing
assembly, the holder must be lowered and the two screws un-
screwed when removing the Mechanism assembly.
Procedures for Lowering the Cassette holder assembly
Turn the loading motor pulley in the direction as indicated by
Fig.2. As both A and B levers are lodged twice, push the
levers in the direction as indicated by Fig.3 to release them.
When pushing the levers, do it in the order of A , B , B , A .
When the holder has been lowered, turn the pulley until the
cassette holder is securely in place without allowing any up/
down movement.
