PROBLEM TO BE SOLVED: To correctly convey a medium by preventing the occurrence of skew.SOLUTION: First conveyance guides formed with convex curved guides curved in a convex shape are arranged between a first driving conveyance roller and a first driven conveyance roller and a second driving conveyance roller and a second driven conveyance roller, a second conveyance guide formed with a concave curved guide surface curved in a concave shape is supported by one of a shaft of the first driving conveyance roller and a shaft of the second driving conveyance roller and is engaged with the other, a curved conveyance path is formed between the concave curved guide surface and the convex curved guide surface, thereby the guide width direction of the concave curved guide surface is made substantially parallel with respect to the longitudinal direction of each of a first roller pressing part and a second roller pressing part, conveyance locus lengths at the time of conveying a medium are made substantially equal in any portion in the medium lateral width direction, and the medium can be correctly conveyed while the occurrence of skew is prevented.SELECTED DRAWING: Figure 3 |
