ABSTRACT:
A conveyance apparatus increases the conveyance precision of a conveyance unit. The conveyance apparatus has first and second conveyance rollers. The conveyance apparatus includes a DC motor serving as a driving source for the conveyance rollers, a first encoder which outputs a first pulse signal in accordance with rotation of the first conveyance roller, a second encoder which outputs a second pulse signal in accordance with rotation of the second conveyance roller, and a control unit having a first mode in which the DC motor is controlled based on first information about the first pulse signal when executing a conveyance operation to convey a sheet by using the first and second conveyance rollers, and a second mode in which the DC motor is controlled based on second information about the second pulse signal when executing a conveyance operation to convey a sheet by using the second conveyance roller.
