Sheet discharging apparatus and image forming apparatus including the same
Provided is a sheet discharging apparatus including a discharge unit configured to discharge a sheet on which a toner image has been heated and fixed, a stacking unit configured to stack the sheet discharged by the discharge unit, a suction unit configured to suck air over the stacking unit, and a cooling unit configured to blow air over the stacking unit on a downstream side of an air suction by the suction unit in a sheet discharge direction by the discharge unit.
1. A sheet discharging apparatus, comprising:
a discharge unit configured to discharge a sheet on which a toner image has been heated and fixed;
a stacking unit configured to stack the sheet discharged by the discharge unit;
a suction unit configured to suck air over the stacking unit; and
a cooling unit configured to blow air over the stacking unit on a downstream side of an air suction by the suction unit in a sheet discharge direction by the discharge unit.
2. A sheet discharging apparatus according to claim 1 ,
wherein the suction unit is configured to suck the air in a direction intersecting with the sheet discharge direction, and
wherein the cooling unit is configured to blow the air in a direction intersecting with the sheet discharge direction and away from a sucking direction by the suction unit.
3. A sheet discharging apparatus according to claim 1 ,
wherein the suction unit is provided on a downstream side of the discharge unit in the sheet discharge direction, and
wherein the cooling unit is provided on a downstream side of the suction unit in the sheet discharge direction.
4. A sheet discharging apparatus according to claim 1 , wherein the suction unit is configured to suck the air from a discharge port direction in which the sheet is discharged by the discharge unit.
5. A sheet discharging apparatus according to claim 1 , wherein the cooing unit is configured to blow the air in a direction inclined to the downstream side in the sheet discharge direction.
6. A sheet discharging apparatus according to claim 1 , wherein the cooling unit is configured to blow the air in an upward direction with respect to a sheet stacking surface of the stacking unit.
7. A sheet discharging apparatus according to claim 1 , further comprising a shielding member provided between an air inlet port of the suction unit and an air outlet port of the cooling unit.
8. A sheet discharging apparatus according to claim 1 , wherein the suction unit is configured to suck the air over the stacking unit while the discharge unit is discharging the sheet.
9. A sheet discharging apparatus according to claim 1 ,
wherein the cooling unit is configured to blow the air over the stacking unit when a number of sheets discharged by the discharge unit is equal to or larger than a predetermined number of sheets.
10. A sheet discharging apparatus according to claim 9 , wherein the cooling unit is configured to blow the air over the stacking unit before the discharge unit discharges a first sheet for a second job subsequent to a first job when a time interval between the first job and the second job implemented by an image forming unit which forms the toner image on the sheet discharged by the discharge unit is a predetermined time interval or shorter.
11. An image forming apparatus, comprising:
the sheet discharging apparatus according to claim 1 ;
an image forming unit configured to form the toner image on the sheet discharged by the discharge unit.
