Abstract:
1. A paper discharge device comprising: a holding unit mounted rotatably to a frame by means of a turning shaft, the holding unit comprising: a recording medium receiving inlet configured to receive a recording medium; a recording medium feeding path through which the recording medium received from the recording medium receiving inlet is conveyed; and a cylindrical housing configured to hold the recording medium received from the recording medium inlet, the turning shaft being positioned along a rotational axis through the center of the cylindrical housing; a driven pinch roller and a driving pinch roller disposed at the recording medium receiving inlet; and a first sensor disposed at the recording medium receiving inlet and a second sensor disposed at the recording medium receiving inlet with the driving pinch roller interposed between the first sensor and the second sensor, wherein the holding unit rotates about the turning shaft to reach a holding position where the recording medium is received from an image forming unit, and the driven pinch roller and the driving pinch roller are rotated until the first sensor detects a first rear end of the recording medium to cause the recording medium to be held within the cylindrical housing, wherein the holding unit rotates about the turning shaft to reach a discharge position where the recording medium is discharged, and the driven pinch roller and the driving pinch roller are rotated until the second sensor detects a second rear end of the recording medium to cause the recording medium to be discharged, wherein if the recording medium is not taken at the discharge position within a predetermined period of time, the driven pinch roller and the driving pinch roller are rotated to cause the recording medium to be held within the cylindrical housing, the holding unit rotates to reach a collecting position where the recording medium is collected in a collecting box, and the driven pinch roller and the driving pinch roller are rotated to cause the recording medium to be discharged into the collecting box.
