1. A transport device for an instant film comprising:
a transport roller pair that includes a capstan roller and a pinch roller facing the capstan roller, and transports any one of a first instant film or a second instant film having a smaller dimension in a width direction than the first instant film in a transport direction orthogonal to the width direction by rotation of the capstan roller and the pinch roller,
wherein the capstan roller includes:
a rotational shaft;
a pair of spike roller members that are provided at both ends of the rotational shaft and have a plurality of convex portions on a circumferential surface, the pair of spike roller members being arranged at intervals from each other so as to correspond to the dimension of the first instant film in the width direction; and
a sub roller member that is provided at the rotational shaft, and is positioned between the pair of spike roller members, the sub roller member being disposed at an interval with respect to one of the pair of spike roller members so as to correspond to the dimension of the second instant film in the width direction,
the pair of spike roller members and the pinch roller transport the first instant film in a state of pinching both side edge portions of the first instant film, and
one of the pair of spike roller members and the pinch roller transport the second instant film in a state where one of the pair of spike roller members and the pinch roller pinch one of side edge portions of the second instant film and the sub roller member is slidably in contact with the other of the side edge portions of the second instant film.
