5.1.1 Tape Feed Lever Forward/Backward Stroke
The tape feed advance and retract stroke sends the tape forward.
The feeder moves the component to the pick-up position with the
forward stroke.
Square-motion type feeders however, advance the tape with the up
and down movement of the tape positioning claw, along with the
forward and backward motion of the tape feed lever.
• Drive Mechanism
The cam starts the tape feed cycle by advancing the lever on the
feeder. The stroke (fixed) depends on the cam curvature.

Note : This jig is also necessary for the tape-positioning claw
adjustment (Section 5.1.2), push-up pin adjustment (Section
5.1.3), and for the tape-end detection adjustments (Section
5.1.4).
1) Set the adjustment jig at D1 on the device table.
• Ensure that there are no obstructions on the base of the jig.
• Confirm that the jig will not interfere with station 1.
Note: It is possible to make the adjustments with the jig set at
