A single-unit processing apparatus 20 is provided in which a processing pitch for processing performed on a workpiece 1a continuous in a transport direction can be changed. A processing apparatus 20 that performs processing on the workpiece 1a continuous in a transport direction while transporting the workpiece 1a in the transport direction, and performs processing on the workpiece 1a at a predetermined processing pitch in a rotational direction of a rotating body 30 that rotates about an axis C30, during movement of the workpiece 1a in the rotational direction by the rotation of the rotating body 30 while the workpiece 1a is wrapped around an outer circumferential face of the rotating body 30, includes: a first processing section 50 that is disposed at a predetermined position in the rotational direction so as to oppose the outer circumferential face 30a of the rotating body 30, second processing sections 32 that are provided at each predetermined angle in the rotational direction on the outer circumferential face 30a of the rotating body 30, and that perform the processing on the workpiece in cooperation with the first processing section 50 when a second processing section 32 opposes the first processing section 50, and a support section 34 that supports the workpiece 1a between the second processing sections 32 and 32, and in which it is possible to change, depending on the processing pitch, a position R at which the support section 34 supports the workpiece 1a.
