Abstract:
1. A transported medium transporting apparatus, comprising: a transported medium transporting device that transports a transported medium in a predetermined transportation direction; and at least one pressing driven roller that is driven so that the pressing driven roller contacts one surface of the transported medium, which is transported by the transported medium transporting device; and a pressing driven roller holder, wherein the pressing driven roller includes a rotary body and a shaft portion, both of which are made of elastic synthetic resin and formed integrally with each other, wherein a plurality of protrusions are formed on the rotary body at regular intervals in a circumferential direction of the rotary body, wherein the shaft portion rotatably supports the rotary body so that the rotary body can be driven, and wherein the pressing driven roller has a shape such that the rotary body contacts the transported medium with a predetermined pressing force owing to an elastic force of the shaft portion, wherein the pressing driven roller holder includes an engaging portion which rotatably supports the shaft portion of the pressing driven roller while maintaining a clearance between the shaft portion and the pressing driven roller holder, and wherein the pressing driven roller contacts the transported medium with a predetermined pressing force without a corresponding drive roller being formed opposite to the pressing driven roller.
