Claim Text:
1. A sheet ejecting device configured to eject a sheet conveyed thereto, comprising: a sheet conveyance path along which the sheet is conveyed; an exit port which is located at a downstream end of the sheet conveyance path in a sheet conveyance direction and from which the sheet is ejected; at least one ejection roller pair configured to eject the sheet, the at least one ejection roller pair being disposed at the exit port and including a drive roller and a driven roller providing a nip therebetween; and a sheet detection portion configured to detect the sheet being ejected, the sheet detection portion being disposed along the sheet conveyance path and located upstream of the at least one ejection roller pair in the sheet conveyance direction, wherein the sheet detection portion includes: the actuator moves between a detectable position where the actuator is detectable by the sensor and an undetectable position where the actuator is not detectable by the sensor, the actuator has a sheet guide portion extending along the sheet conveyance direction, the sheet guide portion is configured to move, in a direction transverse to the sheet conveyance direction such that the actuator moves to the detectable position, by contact with the sheet passing along the sheet conveyance path and guide the sheet in the sheet conveyance direction, the at least one ejection roller pair is a plurality of ejection roller pairs, the drive rollers of the plurality of ejection roller pairs are disposed around a drive roller shaft with a space therebetween, the driven rollers of the plurality of ejection roller pairs are disposed around a driven roller shaft such that each of the driven rollers is located opposite to the corresponding drive roller and provides the nip therebetween, the actuator is disposed between two of the nips that are adjacent to one another in a direction parallel to the drive roller shaft and the driven roller shaft, the actuator further has a pressing face at a downstream end thereof in the sheet conveyance direction, the pressing face being configured to press a top surface of the sheet being conveyed by the ejection roller pairs and ejected from the ejection roller pairs to curve the sheet, and the pressing face is located lower than the nips as viewed in the direction parallel to the drive roller shaft and the driven roller shaft when the actuator is at the undetectable position.
