2.5 DISASSEMBLY/ASSEMBLY OF THE MECHANISM
ASSEMBLY
2.5.1 Introduction
The disassembly and assembly of the mechanism assem-
bly should usually be performed in the ASSEMBLY mode.
(Table 2-5-1)
Note that the mechanism is in the cassette in (C-IN) mode
when the mechanism assembly is taken out of the set and
that the C-IN mode should be switched to the ASSEMBLY
mode in this case.
2.5.2 Mechanism Modes
The mechanism has 6 modes as shown in Table 2-6-1. The
current mode can be confirmed by the positioning of the “ ”
marking on the sub-cam gear and the “ ” marking on the
mechanism.
See the following figures (Figs. 2-5-1 to -6) for details.
Note:
•
This mechanism assembly has another ASSEMBLY
mode. However, this mode cannot be identified from the
markings because it corresponds to an intermediate po-
sition between the C-IN (
C
) mode and S-FF (
H
) mode.
This mode can be confirmed by the rotary encoder
phase. See Fig. 2-5-7.
