With this configuration, the number of drive sources can be reduced, and the overall configuration can be simplified.
[0012]
Further, in the film transport unit according to the present invention, a frame body having the holding means for holding the winding section is detachably provided on the transport section, and the winding section is connected to the transport section via the frame body. A configuration provided detachably can be adopted. According to the film transport unit having such a configuration, whether to remove the frame itself from the transport unit or to remove the winding unit from the frame body can be selected according to the application.
[0013]
Further, the film transport unit according to the present invention is provided with a pair of support frames that rotatably support both ends of the winding drum, and the holding unit has a configuration including a restriction claw that restricts movement of the support frame. Can be adopted. According to the film transport unit having such a configuration, it is possible to prevent the winding section from being inadvertently detached from the transport section by the regulating claw, and when the regulating claw has flexibility, it resists its elastic force. As a result, the winding section can be more easily attached and detached.
