US Patent 7641329 Conveyance control device, conveyance system and image forming system

The conveyance control device includes a detector that detects the conveyance distance of an object by a conveyance device, a section determiner that determines to which section within an object a reference point of the object belongs, and a target setter, based on a determination result of the section determiner, sets the target conveyance speed corresponding to the section to which the reference point belongs. Based on a detection result of the detector, the operation amount calculation sequentially calculates the operation amount of the conveyance device. The conveyance controller provides a control signal corresponding to the operation amount calculated by the operation amount calculator for the conveyance device and makes the conveyance device convey the object to move a reference point of the object from the conveyance start point to the conveyance destination at a speed corresponding to the target conveyance speed.
