7.5 Subscanning Unit
Driving Shaft Roller/Driven Shaft Roller
The IP conveyed to the driven shaft of the scanner unit is conveyed by the driving of FFM
(MZ1) and operation of the driven shaft roller and driving shaft roller to initiate reading.
To drive the upper driven shaft roller and upper driving shaft roller, their respective motors
are used; as the cam attached thereto is rotated, the upper driven shaft roller or upper
driving shaft roller is operated (up and down). The rotation of the cam facilitates smooth up/
down operation of the upper rollers, thereby preventing uneven IP fluctuations.
Driven Shaft Grip
For the IP conveyed to the driven shaft, in order to initiate gripping of the driven shaft roller,
MZ3 is activated to cause the driven shaft roller to move down (descend), thereby gripping
the IP. The descend position is detected as the sensor SZ3 becomes CLOSE from the
OPEN status. After gripping of the driven shaft roller is completed, the driving of FFM (MZ1)
is initiated, thereby conveying the IP to the IP leading-edge sensor (SZ1).
