Abstract
A first lower layer control unit controls a conveyance unit, that conveys the medium in a first conveyance section of a conveyance path. A second lower layer control unit controls a conveyance unit, that conveys the medium in a second conveyance section located downstream of the first conveyance section. An upper layer control unit determines whether the medium is at a position where both the first lower layer control unit and the second lower layer control unit engage with conveyance control of the medium, instructs the first lower layer control unit and the second lower layer control unit to operate in synchronization with each other when the medium is at the position, and instructs the second lower layer control unit to operate asynchronously to the first lower layer control unit when the medium is not at the position.
