Patent ID: 8668200

Claim:
A carrying apparatus comprising: a carry path which is defined to guide a first carried object and a second carried object which is larger in thickness than the first carried object; a first pulley which is configured to be rotated by a drive force generated in a drive source; a first roller which is provided on one side of opposite sides of the carry path; a second pulley which is provided coaxially with the first roller and is configured to be rotated integrally with the first roller; a first belt which is wound on the first pulley and the second pulley and is configured to be moved circumferentially between the first pulley and the second pulley; a first tensioner which is fixed at a position where the first tensioner applies a predetermined tension to the first belt; a first moving mechanism which is configured to move the first roller between (i) a first position at which the first roller carries the first carried object and (ii) a second position which is farther from the carry path than the first position and at which the first roller carries the second carried object; a third roller which is provided on the other side of the carry path so as to be opposed to the first roller located at the first position and which is configured to carry the first carried object, while nipping the first carried object with the first roller; and a fourth roller which is provided on the other side of the carry path so as to be opposed to the first roller located at the second position and which is configured to carry the second carried object, while nipping the second carried object with the first roller, wherein the second position is a position at which a tension by the first tensioner to the first belt is substantially equal to the predetermined tension applied by the first tensioner to the first belt where the first roller is positioned at the first position.
