Claim:
A sheet discharging device, comprising: a housing including a first wall; a discharge section configured to discharge a sheet to an outside of the housing through a slit defined in the first wall, the discharge section discharging the sheet after one surface of the sheet is heated, the sheet being a first sheet or a second sheet with a width different from that of the first sheet; first and second pressing portions attached to the housing so that the pressing portions press an upper surface of the sheet discharged through the slit outside the slit, the pressing portions being movable between a first pressing position for pressing a lateral edge of the first sheet and a second pressing position for pressing a lateral edge of the second sheet; a moving unit configured to be mounted on the housing, to support the pressing portions rotatably thereon and to move the pressing portions along the slit, the moving unit including a first rack connected to the first pressing portion so that the first rack extends along the slit, a second rack connected to the second pressing portion so that the second rack extends along the slit, and a rotor including a pinion engaged with the first and the second racks; a driving source configured to rotate the rotor in forward and reverse directions; and a transmitting portion configured to transmit a driving force of the driving source from the discharge section to the rotor, wherein: the discharge section includes a roller shaft to be rotated by the driving source and a roller integrally rotated with the roller shaft and configured to discharge the sheet through the slit; the transmitting portion includes a tubular gear mounted on the roller shaft so that the tubular gear rotates together with the roller shaft; and the rotor includes rack teeth engageable with the tubular gear.
