Main Lever Latching Action - Polaroid Miniportrait 455 Repair Manual

5. No exposure of the film occurs during this shutter charging process, since the ears on
the light interception blade (g) cover the exposure holes in the shutter blade (h), and
both blades turn together in this shutter charging process.
6. The main lever (f), shown in a top view in Figure 2-2 continues to rotate and turns the
magnet set lever (i) clockwise. Hook (j) linked to the magnet set lever is attracted to
the magnet.
7. Main lever (f) now reverses its direction (U-shaped arrow, Figure 2-2), because of the
action of cam (b) (Figure 2-1). The tooth at the end of the main lever latches to the
hook (j). Shutter blade (h) is now charged (cocked); the cocking lever (e) and light
interception blade (g) return to their original positions.
