Fastening the PLATE
1 The DUPLEX CAM moves from position 1 directly to position 3. See “DUPLEX CAM
AY.”
2 When the CAM rotates, the SLED CAM and the HOOK CAM execute the following
actions. The first degrees of the CAM rotation move the HOOKS up. The remaining part
of the rotation releases the LATCHES of the CASSETTE and fastens the PLATE to the
EXTRACTION BAR.
• SLED CAM actions:
– SLED PLATE moves 1.5240 cm (0.600 in.) forward
– PIVOTING PLUSH rotates to make a light-tight environment around the
CASSETTE
• HOOK CAM actions:
– HOOK CAM moves against the HOOK YOKE FOLLOWER, which starts the
mechanical sequence to extend the HOOKS on the EXTRACTION BAR into the
LATCH AY. See “Plate Handling.”
– With the HOOKS in position inside the CASSETTE, the forward motion of the
SLED causes the SPRING-LOADED LATCH inside the PLATE to release and
fastens the PLATE to the EXTRACTION BAR.
3 The MSC BOARD A1 sends a signal to the MCPU BOARD that the CASSETTE is
loaded.
