<P>PROBLEM TO BE SOLVED: To provide a carrying vehicle for a roll body at a low price which can detect that an insertion part interferes with an edge of the roll body. <P>SOLUTION: A freely traveling truck body includes: a movement handling means for handling to move a pair of bases which mount and support both edges of a shaft part to the body of a truck; an imaging means for imaging the insertion part of a roll body holding device and the shaft part of the body of a roll; and a control means for controlling operation of the movement handling means based on imaging information of the imaging means. The control means is configured to execute positioning treatment in a state in which the truck body is stopped at a setting stop position, and discriminate as a failure when it is detected that the shaft part moves to the truck body based on the imaging information of the imaging means in a state in which the operation of the movement handling means is paused. <P>COPYRIGHT: (C)2012,JPO&INPIT |
