2.3 DISASSEMBLY/ASSEMBLY OF MECHANISM
ASSEMBLY

2.3.1 General statement

The mechanism should generally be disassembled/assem-
bled in the EJECT mode (ASSEMBLY mode). (Refer to Fig.
2-3-1.)
However, when the mechanism is removed from the main
body, it is set in the STOP mode. Therefore, after the
mechanism is removed from the main body, supply 3 V DC
to the electrode on the top of the loading motor to enter
the mechanism mode into the EJECT mode compulsory.

2.3.2 Explanation of mechanism mode

The mechanism mode of this model is classified into six
modes as shown in Table 2-3-1. Each mechanism mode
can be distinguished from others by the relative position
of " " mark on the sub cam gear to the inner or outer pro-
trusion on the main deck.
Refer to Fig. 2-3-2 to 2-3-8 below.
The EJECT mode, C IN mode and SHORT FF mode should
be recognized by the relative position of the " " mark to
the inner protrusion, while the STOP mode, REV mode and
PLAY mode should be recognized by that to the outer pro-
trusion.
