PROBLEM TO BE SOLVED: To provide a conveyance device capable of feeding an object with high precision. SOLUTION: When a link member 18c is rotated to the direction C, a pulley 18b is moved from a position shown by the two-dot line to a position shown by the continuous line so that a curvature radius of a conveyor belt 17a guided between a pulley 18a and the pulley 18b changes from a curvature radius R1 to a curvature radius R2. Thereby, a radius curvature at a contact part between a pin 17b and an addition member 4 is enlarged so that it is as if a pulley diameter gets enlarged toward a discharge port of an addition member feeder 17. As a result, a feeding speed VP at the time of transferring an addition member 4 onto a base paper 1 gets nearly equal to a feeding speed VS1 in time of feeding the addition member 4 along a guide member 17f.
