4.2
Disassembly/assembly of the mechanism assembly
4.2.1 Introduction
The disassembly and assembly of the mechanism assembly should usually be performed in the ASSEMBLY mode.(Table 4-2-1)
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.
To set the ASSEMBLY mode, apply 3 V DC to the electrodes on the upper part of the loading motor as shown in Fig. 4-2-7.

4.2.2 Mechanism modes
The mechanism has 6 modes as shown in Table 4-3-1. 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. 4-2-1 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 position between the C-IN ( C ) mode and S-FF ( H ) mode. This mode can be confirmed by the
rotary encoder phase. See Fig. 4-2-7.
