Abstract

A discharging device includes: a pair of medium supporting portions that are provided so as to face each other in a width direction intersecting a transporting direction in which a medium is transported and that support the medium that is transported; and a stacking portion that is provided vertically below the pair of medium supporting portions and on which the medium that drops from the pair of medium supporting portions is stacked, each of the pair of medium supporting portions is configured to move in the width direction, the pair of medium supporting portions are configured to be arranged, after the medium is dropped onto the stacking portion, at positions at which a distance in the width direction becomes a predetermined distance, and the predetermined distance varies in accordance with a width of the medium stacked on the stacking portion.

First claim

What is claimed is:

1. A discharging device comprising:
a pair of medium supporting portions that are provided so as to face each other in a width direction intersecting a transporting direction in which a medium is transported and that support the medium that is transported; and
a stacking portion that is provided vertically below the pair of medium supporting portions and on which the medium that drops from the pair of medium supporting portions is stacked, wherein
each of the pair of medium supporting portions is configured to move in the width direction,
the pair of medium supporting portions are arranged, after the medium is dropped onto the stacking portion, at positions at which a distance in the width direction becomes a predetermined distance,

the pair of medium supporting portions does not overlap with sides of the medium in a vertical direction when the pair of medium supporting portions are arranged at the positions at which the distance in the width direction becomes the predetermined distance, and
the predetermined distance varies in accordance with a width of the medium stacked on the stacking portion.

2. The discharging device according to claim 1 , wherein
when one job is executed for the medium in a stage before the medium is transported to the pair of medium supporting portions, after one set of medium, which corresponds to the one job, drops onto the stacking portion from the pair of medium supporting portions, the pair of medium supporting portions are arranged at the positions at which the distance becomes the predetermined distance.

3. The discharging device according to claim 1 , wherein
the stacking portion is configured to
be raised/lowered by a moving mechanism and
be stopped between an upper limit position and a lower limit position when being raised/lowered.

4. The discharging device according to claim 3 , wherein
the stacking portion is configured to move to a removal position that is lower than a receiving position at which the medium that drops from the pair of medium supporting portions is received.

5. The discharging device according to claim 1 , wherein
when the width of the medium stacked on the stacking portion is equal to or more than a predetermined width, the pair of medium supporting portions are arranged at positions at which a distance between portions which are farthest in the width direction becomes the predetermined distance which is less than the width of the medium stacked on the stacking portion.

6. The discharging device according to claim 1 , wherein
when the width of the medium stacked on the stacking portion is less than a predetermined width, the pair of medium supporting portions are arranged at positions at which a distance between portions which are closest in the width direction becomes the predetermined distance which is greater than the width of the medium stacked on the stacking portion.

7. A processing apparatus comprising:
a processing portion that performs processing of a medium; and
the discharging device according to claim 1 , which receives, by the medium supporting portions, the medium that passed through the processing portion.

8. A recording apparatus including
a recording portion that performs recording on a medium and
a discharging portion that discharges the medium on which the recording was performed by the recording portion; and
the processing apparatus according to claim 7 , including
a medium leading portion that leads the medium discharged from the discharging portion, wherein
the processing apparatus performs processing of the medium led from the medium leading portion by a processing portion.

9. A discharging device comprising:
a pair of medium supporting portions that are provided so as to face each other in a width direction intersecting a transporting direction in which a medium is transported and that support the medium that is transported; and
a stacking portion that is provided vertically below the pair of medium supporting portions and on which the medium that drops from the pair of medium supporting portions is stacked, wherein
each of the pair of medium supporting portions is configured to move in the width direction,
the pair of medium supporting portions are arranged, after the medium is dropped onto the stacking portion, at positions at which a distance in the width direction becomes a predetermined distance,
the predetermined distance varies in accordance with a width of the medium stacked on the stacking portion, and
when the width of the medium stacked on the stacking portion is equal to or more than a predetermined width, the pair of medium supporting portions are arranged at positions at which a distance between portions which are farthest in the width direction becomes the predetermined distance which is less than the width of the medium stacked on the stacking portion.

10. The discharging device according to claim 9 , wherein
when the width of the medium stacked on the stacking portion is less than a predetermined width, the pair of medium supporting portions are arranged at positions at which a distance between portions which are closest in the width direction becomes the predetermined distance which is greater than the width of the medium stacked on the stacking portion.

11. A processing apparatus comprising:
a processing portion that performs processing of a medium; and
the discharging device according to claim 9 , which receives, by the medium supporting portions, the medium that passed through the processing portion.

12. A recording system comprising:
a recording apparatus including
a recording portion that performs recording on a medium and
a discharging portion that discharges the medium on which the recording was performed by the recording portion; and
the processing apparatus according to claim 11 , including
a medium leading portion that leads the medium discharged from the discharging portion,
wherein the processing apparatus performs processing of the medium led from the medium leading portion by a processing portion.

13. The discharging device according to claim 9 , wherein
the pair of medium supporting portions are configured to be arranged at the positions at which the distance becomes the predetermined distance at an arbitrary timing.

14. A discharging device comprising:
a pair of medium supporting portions that are provided so as to face each other in a width direction intersecting a transporting direction in which a medium is transported and that support the medium that is transported; and
a stacking portion that is provided vertically below the pair of medium supporting portions and on which the medium that drops from the pair of medium supporting portions is stacked, wherein
each of the pair of medium supporting portions is configured to move in the width direction,
the pair of medium supporting portions are arranged, after the medium is dropped onto the stacking portion, at positions at which a distance in the width direction becomes a predetermined distance,
the predetermined distance varies in accordance with a width of the medium stacked on the stacking portion, and
when the width of the medium stacked on the stacking portion is less than a predetermined width, the pair of medium supporting portions are arranged at positions at which a distance between portions which are closest in the width direction becomes the predetermined distance which is greater than the width of the medium stacked on the stacking portion.

15. The discharging device according to claim 9 , wherein
when the width of the medium stacked on the stacking po
