Abstract

A sheet discharging device includes: a pair of medium supporting portions that have support surfaces that support the medium, and support the transported medium by the support surfaces; a stacking portion which is provided vertically below the pair of medium supporting portions and on which the medium dropped from the pair of medium supporting portions is stacked; and a standing wall that aligns the medium by contacting a rear end of the medium in the transport direction supported by the pair of medium supporting portions, and the standing wall includes: a center contacting wall that is provided at a center in the width direction and contacts the rear end of the medium; and recess portions that are provided on both sides of the center contacting wall in the width direction and are recessed in a direction away from the support surfaces.

First claim

What is claimed is:

1. A sheet discharging device comprising:
a pair of medium supporting portions that are provided to face each other in a width direction intersecting a transport direction in which a medium is transported, have support surfaces that support the medium, and support the transported medium by the support surfaces;
a stacking portion which is provided vertically below the pair of medium supporting portions and on which the medium dropped from the pair of medium supporting portions is stacked; and
a standing wall that aligns the medium by contacting a rear end of the medium, in the transport direction, supported by the pair of medium supporting portions, wherein
the support surfaces are inclined upward toward a downstream in the transport direction, and
the standing wall includes:
a center contacting wall that is provided at a center in the width direction and contacts the rear end of the medium; and
recess portions that are provided on both sides of the center contacting wall in the width direction and are recessed in a direction away from the support surfaces.

2. The sheet discharging device according to claim 1 , wherein
the pair of medium supporting portions are movable in the width direction, and
the center contacting wall guides the medium to the stacking portion when the pair of medium supporting portions move in directions away from each other and the medium is dropped.

3. The sheet discharging device according to claim 1 , wherein
the standing wall further includes a stacking standing wall that aligns the medium by contacting the rear end of the medium supported by a stacking surface of the stacking portion, and
the center contacting wall and the stacking standing wall have contact surfaces that contact the rear end of the medium in a same plane.

4. The sheet discharging device according to claim 1 , further comprising:
a plurality of receiving portions that are movable between a protrusion position where the receiving portions protrude into the recess portions on both sides of the center contacting wall and a retraction position where the receiving portions are retracted from the recess portions, wherein
the plurality of receiving portions align the rear end of the medium supported by the support surfaces together with the center contacting wall in the protrusion position.

5. The sheet discharging device according to claim 4 , wherein
when the pair of medium supporting portions drop the medium onto the stacking portion, the plurality of receiving portions move to the retraction position.

6. The sheet discharging device according to claim 1 , wherein
the recess portions are configured so that at least a part of the rear end of the medium stacked on the stacking portion enters.

7. The sheet discharging device according to claim 1 , wherein
the stacking portion has a stacking surface inclined upward toward the downstream in the transport direction, and
the recess portions have aligning surfaces orthogonal to the stacking surface.

8. A processing device comprising:
a processing section that performs processing on a medium;
a pair of medium supporting portions that are provided to face each other in a width direction intersecting a transport direction in which the medium is transported from the processing section, have support surfaces that support the medium, and support the transported medium by the support surfaces;
a stacking portion which is provided vertically below the pair of medium supporting portions and on which the medium dropped from the pair of medium supporting portions is stacked; and
a standing wall that aligns the medium by contacting a rear end of the medium in the transport direction supported by the pair of medium supporting portions, wherein
the support surfaces are inclined upward toward a downstream in the transport direction, and
the standing wall includes:
a center contacting wall that is provided in a center in the width direction and contacts the medium, and
recess portions that are provided on both sides of the center contacting wall in the width direction and are recessed in a direction away from the support surfaces.

9. A recording system comprising:
a recording device including
a recording section that performs recording on a medium, and
a discharge section that discharges the medium on which the recording is performed by the recording section; and

a processing device including
a medium introducing portion that introduces the medium discharged from the discharge section,
a processing section that performs processing on the medium introduced from the medium introducing portion,
a pair of medium supporting portions that are provided to face each other in a width direction intersecting a transport direction in which the medium is transported from the processing section, have support surfaces that support the medium, and support the transported medium by the support surfaces,
a stacking portion which is provided vertically below the pair of medium supporting portions and on which the medium dropped from the pair of medium supporting portions is stacked, and
a standing wall that aligns the medium by contacting a rear end of the medium in the transport direction supported by the pair of medium supporting portions, wherein
the support surfaces are inclined upward toward a downstream in the transport direction, and
the standing wall includes:
a center contacting wall that is provided in a center in the width direction and contacts the medium, and
recess portions that are provided on both sides of the center contacting wall in the width direction and are recessed in a direction away from the support surfaces.
