CHAPTER 7 PICK-UP/FEEDING SYSTEM
4. Cassette Pick-U Operation
a. Rotating the Pick-Up Roller
The pick-up roller is rotated by the drive of the cassette pick-up motor (M5) transmitted by a
gear. The upper or lower cassette pick-up operation is driven by rotating the cassette pick-up motor
clockwise or counterclockwise.
b. Switching the Drive of the Pick-Up Roller
When the cassette pick-up roller rotates clockwise, the gear 1 moves up to drive the upper pick-
up roller. When the roller rotates counterclockwise, on the other hand, the gear 1 move down to
drive the lower pick-up roller. Figure 7-107 shows how the pick-up roller is controlled.
c. Pick-Up Roller Shaft Reference
When the cassette is set, the pick-up roller is moved down or the lifter is moved up with
reference to the position of the pick-up roller shaft.
