A print medium conveyance device 40 has a tractor 44, conveyance roller 55, and clutch mechanism 83. The tractor 44 sequentially engages engagement holes formed in a line in the medium and conveys the print medium in a specific conveyance direction X. The conveyance roller 55 is disposed downstream from the tractor 44 in the conveyance direction X, and has a friction layer 59 containing an inorganic particle dispersion formed on the surface. the clutch mechanism 83 is between the conveyance motor 72 and tractor 44, and interrupts transfer of drive power from the conveyance motor 72 to the tractor 44 at least in part under a specific condition. The print medium can therefore be conveyed with high precision while damage to the print medium by excessive tension can be prevented. |
