The invention provides a conveyance device and an image inspection device. A hanging prevention roller 16 is installed between a first suction conveyance unit 1 on an upstream side and a second suction conveyance unit 2. When an inspection object is sent from the first suction conveyance unit 1 into the second suction conveyance unit 2, a front edge of the inspection object abuts on and runs on the hanging prevention roller 16 before the front edge of the inspection object hangs down under its own weight or due to downward curling and so forth; the inspection object is sandwiched between the hanging prevention roller 16 and the second suction conveyance unit 2, and thereby stable suction conveyance is started without delay. 本发明提供输送装置和图像检查装置。在上游侧的第1吸附输送部(1)与下游侧的第2吸附输送部(2)之间设置防下垂辊(16)。在自第1吸附输送部(1)向第2吸附输送部(2)送入了被检查物时，在被检查物的前端因自重或向下方的卷曲等而下垂之前，该前端与防下垂辊(16)抵接并爬上该防下垂辊(16)，该被检查物被夹在防下垂辊(16)与第2吸附输送部(2)之间，并无延迟地开始稳定的吸附输送。
