Abstract
A printing device includes a printing unit, a pair of transporting rollers (a pair of rollers) that is disposed right before the printing unit and that transport a medium to the printing unit, and a transportation direction changing mechanism that is disposed on an upstream side of the pair of transporting rollers and that changes a transportation direction of the medium before the medium is nipped by the pair of transporting rollers. The transportation direction changing mechanism changes a transportation direction of a following medium such that a leading end portion of the following medium overlaps a preceding medium when the printing unit performs printing in a state where the preceding medium is nipped by the pair of transporting rollers.
Claims9
A printing device comprising:
- a printing unit that performs printing on a transported medium;
- a first pair of rollers that is disposed right before the printing unit and that rotates while nipping the medium to transport the medium to the printing unit;
- a second pair of rollers that is disposed on an upstream side of the first pair of rollers and that transports the medium;
- and
- a transportation direction changing mechanism that is disposed on an upstream side of the first pair of rollers and that changes a transportation direction of the medium before the medium is nipped by the first pair of rollers,
- wherein, the transportation direction changing mechanism changes a transportation direction of a following medium such that a leading end portion of the following medium overlaps a preceding medium when the printing unit performs printing in a state where the preceding medium is nipped by the first pair of rollers,
- wherein the transportation direction changing mechanism is a flap that is disposed on a downstream side of the second pair of rollers and is disposed right after the second pair of rollers, and
- wherein the flap includes a surface that extends along a direction intersecting a tangential direction at a nip point between the second pair of rollers and the surface comes into contact with the medium which is transported being nipped by the second pair of rollers so that the transportation direction of the medium is changed.
