PROBLEM TO BE SOLVED: To provide a circuit board transportation mechanism and a component mounting apparatus capable of easily performing product class changing operation for handling plural kinds of circuit boards different from each other in length.SOLUTION: A circuit board transportation mechanism 2 has an operation unit 14B in which the area length is changeable according to the length dimension of an operation area 13B where circuit board 3A of a length dimension La and a circuit board 3B of a length dimension Lb are handled. Pulleys for adjusting conveyor belt 14b comprise: a pulley 27b as a first pulley which is commonly used for any of the circuit boards 3A and 3B; and pulleys 26c and 27a as second pulleys which are selectively used for handing either one of the circuit boards 3A and 3B. The belt adjusting mode of the conveyor belt 14b of an identical belt length which is adjusted by the first pulley, the second pulley and plural pulleys of a second belt drive mechanism 15B is changed to change the distance between the first pulley and the second pulley according to the area length.
