Driving Shaft Grip
For the IP conveyed from the driven shaft roller, the IP leading edge is detected, and then
image reading is initiated.
After the IP leading edge is detected (by SZ1), MZ2 is activated when the IP is conveyed by
a predetermined amount, so that the driving shaft roller slowly descends to grip the IP.
The descend position is detected as the sensor SZ2 becomes OPEN from the CLOSE
status.
FFM (MZ1) Driving
The driving shaft driven by FFM (MZ1) transfers its drive to the driven shaft through the steel
belt. By use of the steel belt, belt elongation and so forth is prevented, while transferring the
reading speed from FFM (MZ1) accurately.
Furthermore, by gripping the IP conveyed, the IP can be read accurately while maintaining
the reading speed constant.
