TRANSFER APPARATUS, LIQUID EJECTION APPARATUS, READING APPARATUS, IMAGE FORMING APPARATUS, CONTROL METHOD OF THE TRANSFER APPARATUS

A transfer apparatus includes a head unit (210C, 210K) to process an object (W) transferred in a transfer direction, a first support member disposed upstream in the transfer direction with respect toa process position to support the object, a second support member disposed downstream in the transfer direction of the process position to support the object, a surface detector between the first andsecond support members to detect first surface information of the object, an upstream surface detector disposed upstream in the transfer direction with respect to the surface detector to detect secondsurface information of the object, an edge detector disposed closer to the upstream surface detector than the surface detector in the transfer direction to detect an edge of the object, and a controller to move the head unit based on detection results of the surface detector and the upstream surface detector and a detection result of the edge detector. 一种传送设备包括头单元(210C，210K)，用于处理在传送方向上被传送的物体(W)；第一支撑构件，其布置在相对于处理位置在传送方向上的上游，
