2.2 DISASSEMBLY/ASSEMBLY OF MECHANISM
ASSEMBLY
2.2.1 General statement
The mechanism should generally be disassembled/assem-
bled in the EJECT mode (ASSEMBLY mode). (Refer to Fig.
2-2-1.)
However, when the mechanism is removed from the main
body, it is set in the STOP mode. Therefore, it is required to

2.2.2 Explanation of mechanism mode
The mechanism mode of this model is classified into six
modes as shown in Table 2-2-1. Each mechanism mode can
be distinguished from others by the relative position of “
䢇
”
mark on the sub cam gear to the inner or outer protrusion
on the main deck.

shift the mechanism mode from the STOP mode to the EJECT
mode after the mechanism is removed from the main body.
In such the case, supply 3 V DC to the electrode on the top
of the loading motor to enter the mechanism mode into the
EJECT mode.
Refer to Fig. 2-2-2 to 2-2-7 below.
The EJECT mode, C IN mode and SHORT FF mode should
be recognized by the relative position of the “
䢇
” mark to the
inner protrusion, while the STOP mode, REV mode and PLAY
mode should be recognized by that to the outer protrusion.
