Paper inside a cassette is lifted up by the Lifting Plate.
The Lifting Plate is lifted up by rotating the Cassette Lifter Motor (M4).
The paper surface is detected by the Cassette Paper Surface Sensor (PS12).
When the Lifting Plate is rising, the Lifter Motor (M4) is controlled to keep the paper surface steady so that pickup can be performed
stably.
