A conveyance control device includes a drive mechanism to drive a reciprocating body, an origin sensor, a drive amount detection unit for detecting the drive amount of the drive mechanism, and a movement detection unit for optically detecting the reciprocating body's shifting from a resting state to a moving state. After the reciprocating body is moved in one direction until the origin sensor turns from a first output state to a second output state, the reciprocating body is moved in the opposite direction until the origin sensor turns back to the first output state. A first drive amount from when the origin sensor turns to the second output state to when the reciprocating body shifts from the resting state to the moving state, and a second drive amount from when the reciprocating body shifts to the moving state to when the origin sensor turns to the first output state are acquired.
