Abstract
A medium transport device includes a drive source, a transport path through which a medium is transported in a transport direction between a first path surface and a second path surface located away from the first path surface, a plurality of projecting portions that projects from the first path surface and is arranged in a width direction intersecting the transport direction, and a moving portion that changes a projecting amount of the projecting portions with respect to the first path surface by power of the drive source between the first path surface and the second path surface.
Claims15
A medium transport device comprising:
- a drive source;
- a transport path through which a medium is transported in a transport direction between a first path surface and a second path surface located away from the first path surface;
- a plurality of projecting portions that projects from the first path surface and is arranged in a width direction intersecting the transport direction;
- and
- a moving portion that receives power transmitted from the drive source and that changes a projecting amount of the projecting portions with respect to the first path surface between the first path surface and the second path surface, wherein
- the moving portion includes an abutting portion configured to abut against the projecting portions,
- the projecting portions include a plurality of projections provided in a width direction intersecting the transport direction, a supporting portion that supports the projections, and an abutted portion against which the abutting portion abuts, and
- at least part of the moving portion overlaps the drive source when viewed in the transport direction.
A medium transport device comprising:
- a drive source;
- a transport path through which a medium is transported in a transport direction between a first path surface and a second path surface located away from the first path surface;
- a plurality of projecting portions that projects from the first path surface and is arranged in a width direction intersecting the transport direction;
- a moving portion that receives power transmitted from the drive source and that changes a projecting amount of the projecting portions with respect to the first path surface between the first path surface and the second path surface;
- a first path through which the medium is transported in the transport direction without being curved and reversed;
- a second path through which the medium is curved and reversed, and transported in the transport direction;
- and
- a switching unit that switches between the first path and the second path, wherein
- the projecting portions are fixed at least at two positions in a projecting direction,
- when the respective projecting portions are at a position of transporting a first medium, the switching unit is in a position where the first medium is configured to be transported through the second path, and
- when the respective projecting portions are at a position of transporting a second medium thicker than the first medium, the switching unit is in a position where the second medium is configured to be transported through the first path.
