1. Assembly and Adjustment of Shutter and Film Transport Mechanism
a. SHUTTER CURTAINS
Insert the 2nd curtain pinion shaft
(05062)
and pinion shaft collar (05135), one after another, into the top
mec. plate (03001), and retain (05135) with the pinion shaft collar retainer screw (05136).
Check if the clearance between the pinion shaft collar (05135) and the top mec. plate (03001) along the shaft
direction is adequate. The pinion shaft will not rotate smoothly without an adequate clearance. Adjustment of
the clearance should be made with (W6) washers.
Ease the pinion shaft collar retainer screw (05136). Shift the pinion shaft collar (05135) downward. Apply
(L-1) lubricant between (05062) and (03001) and then fix (05135) at its original position.
Fix the bottom shaft rest assembly (05003) to the body proper (01001) with the mec. plate retainer screw
(03072) and screw (SM 1.7 x 2.5).
Insert the 1st curtain pinion shaft (05061) into the top mec. plate (03001). Insert the curtain shaft collar D
(05076) and two 1st curtain wind shafts (05066) into (05061), and fix (05066) to (05061) with two pinion
shaft retainer screws (05102).
Insert the 1st curtain roller (05067) and then the 2nd curtain wind shaft (05065), around which the 2nd shutter
curtain is glued, to (05062), and fix (05065) to (05062) with one of the pinion shaft retainer screws (05102).
Insert the curtain shaft collar C (05075) into (05061), and (05067) and (05076) into (05062), respectively.
Install the bottom ends of (05061) and (05062) into the respective holes of (05003), assemble (03001) with
(01001), and retain (03072) with screw (FM 1.7 x 3).
Check if the clearance of the 1st curtain pinion shaft (05061) along the shaft direction is adequate. Adjustment
of the clearance should be made with (W6) washers, putting them between (05003) and (05075).
Insert two 2nd curtain rollers (05068) and one curtain shaft collar A (05073) into the 1st curtain spring shaft
(05059) to which the 1st curtain is fixed. Insert the other curtain shaft collar A (05073) into the 2nd curtain
spring shaft (05060) to which the 2nd curtain is fixed.
Insert (05059) and (05060) to the respective holes of (01001), and install the curtain shaft seat (05001) in
(05059) and (05060) through the bottom of (01001), and retain (05001) with three small screws
(SM 1.7 x 3).
Screw one worm wheel (05040) to (05059) and another to (05060).
Slowly rotate (05040) counter-clockwise 2 or 3 times with a screw-driver to tension the curtain springs. Install
the worm (05041) in the hole of (05001) and gear it with (05040). Lightly screw two set screws (Set T 1.4 x 2)
in (05001).
Final adjustment of the curtain spring tension should be made when adjusting the curtain travel speed
mentioned elsewhere.
