When the lift-up cam is unfixed, the lift-up arm lifts up the lifter gear one tooth by the rota-
tion of the lift-up cam. The paper lifting plate is lifted up by repeating the operation. (See
Figure 2-5-10)
When the paper on the paper lifting plate touches the pick-up roller, the pick-up roller shaft
is lifted up. Then, the fixing arm is released, and the lift-up release arm lifts up the pick-up
roller shaft to the waiting position by force of the spring. At the same time, the pick-up roller
shaft fixing arm and the lift up release arm are driven to fix the lift up cam. As a result, the
lift up arm is stopped and lift up operation is competed. (See Figure 2-5-11)
