1. An original reading device comprising:
an original transport path formed from an original loading tray to an original output position by way of an original reading position;
a registration roller located upstream of the original reading position along an original feeding direction for adjusting the timing of feeding an original to the original reading position;
at least one original feed roller for transporting the original which has been fed from the original loading tray into the original transport path toward the registration roller; and
a rotary motion controller arranged to cause said at least one original feed roller to stop after a leading edge of the original has come into contact with the registration roller and causes the original feed roller closest to the registration roller to restart rotating approximately when a rear part of the original close to a trailing edge thereof passes over the original feed roller closest to the registration roller such that the trailing edge of the original and a leading edge of a subsequent sheet contact the original feed roller closest to the registration roller at the same time.
