Abstract

A liquid discharging apparatus includes a transporting belt having an endless shape stretched over a plurality of rollers and configured to rotate while supporting a medium, to transport the medium in a transport direction, a liquid discharging unit configured to discharge a liquid onto the medium, and a flat plate portion for supporting the transporting belt from a side of a contact face with the roller. the flat plate portion includes an edge extending from one end of the transporting belt to the other end of the transporting belt along an extending direction intersecting the transport direction, the edge being formed by a transporting belt support face for supporting the transporting belt and a face facing upstream in a rotation direction of the transporting belt when transporting the medium in the transport direction. the edge is disposed to abut against the transporting belt along the extending direction.

Claims (33)

1. A liquid discharging apparatus comprising:

a transporting belt having an endless shape stretched over a plurality of rollers and configured to rotate while supporting a medium, by a support face being a face on an opposite side from a contact face with the roller, to transport the medium in a transport direction;

a liquid discharging unit configured to discharge a liquid onto the medium supported by the support face; and

a flat plate portion for supporting the transporting belt from a side of the contact face, wherein

the flat plate portion includes an edge extending from one end of the transporting belt to the other end of the transporting belt along an extending direction intersecting the transport direction, the edge being formed by a transporting belt support face for supporting the transporting belt and a face facing upstream in a rotation direction of the transporting belt when transporting the medium in the transport direction,

the edge is disposed to abut against the transporting belt along the extending direction, and

the flat plate portion includes a groove provided along the extending direction, and the edge is formed by the transporting belt support face and a face, facing upstream, in the groove.

2. The liquid discharging apparatus according to claim 1 , wherein

the edge is provided at an upstream end of the flat plate portion.

3. The liquid discharging apparatus according to claim 1 , wherein

the flat plate portion is provided at a position facing the liquid discharging unit.

4. The liquid discharging apparatus according to claim 1 , wherein

the transporting belt has an adhesive applied at the support face,

the medium is transported in a state of being affixed by the adhesive to the support face at least from an affixation position at which the medium is affixed to a position where the medium passes a region facing the liquid discharging unit, and

at the affixation position, a press roller configured to press the medium against the support face and the flat plate portion provided at a position facing the press roller are formed.

5. A liquid discharging apparatus comprising:

a transporting belt having an endless shape stretched over a plurality of rollers and configured to rotate while supporting a medium, by a support face being a face on an opposite side from a contact face with the roller, to transport the medium in a transport direction;

a liquid discharging unit configured to discharge a liquid onto the medium supported by the support face; and

a flat plate portion for supporting the transporting belt from a side of the contact face, wherein

the flat plate portion includes an edge extending from one end of the transporting belt to the other end of the transporting belt along an extending direction intersecting the transport direction, the edge being formed by a transporting belt support face for supporting the transporting belt and a face facing upstream in a rotation direction of the transporting belt when transporting the medium in the transport direction,

the edge is disposed to abut against the transporting belt along the extending direction, and

the extending direction in which the edge extends is out of alignment with respect to a width direction of the transporting belt, the width direction being orthogonal to the transport direction.

6. A liquid discharging apparatus comprising:

a transporting belt having an endless shape stretched over a plurality of rollers and configured to rotate while supporting a medium, by a support face being a face on an opposite side from a contact face with the roller, to transport the medium in a transport direction;

a liquid discharging unit configured to discharge a liquid onto the medium supported by the support face; and

a flat plate portion for supporting the transporting belt from a side of the contact face, wherein

the flat plate portion includes an edge extending from one end of the transporting belt to the other end of the transporting belt along an extending direction intersecting the transport direction, the edge being formed by a transporting belt support face for supporting the transporting belt and a face facing upstream in a rotation direction of the transporting belt when transporting the medium in the transport direction,

the edge is disposed to abut against the transporting belt along the extending direction,

a foreign material receiving section for receiving a foreign material adhering to the edge is provided, and

a movement section is provided that is configured to move the foreign material adhering to the edge toward the foreign material receiving section.

7. The liquid discharging apparatus according to claim 6 , comprising

a cleaning section configured to clean the transporting belt, wherein

the cleaning section also serves as the foreign material receiving section.
