Note that the above-mentioned members only show those related to the paper feeding/conveying system.

In a copying machine configured in this way, the paper feed cassette 3
The copy paper P taken out from the paper passes through the paper feed path 4 and reaches the registration rollers 5, where it is sent to the transfer section 7 in synchronization with the rotation of the photoconductor tram 6, where the toner image is transferred. , and is sent to the fixing roller 9 by the conveyor belt 8. The thermally fixed copy paper P is discharged from the feed roller 10, through a guide path l2 with a guide roller l1 provided in the middle, and to a paper discharge device 2 provided at the bottom of the main body 1 through a discharge port 13. Ru.

FIG. 1 is an external view of a first embodiment of a paper discharge device according to the present invention, in which 14 is an endless paper storage belt (paper discharge receiving means), 15 is a driven roller, 16 is a drive roller, The paper storage belt 4 is stretched over both of them. 17 is a drive transmission belt, 18 is a driven pulley, 19 is a drive pulley,
20 is a motor. The drive transmission bell l-17 is spanned between both boars 18 and 19, and the drive pulley 19 is fixed to the drive shaft of the motor 20.

In the paper ejection device W2 having such a configuration, the ejection port roller 13
The ejected copy sheets P are sequentially stocked onto the stationary paper storage belt 14.

When one cycle of copying is completed, the motor 20 is rotated by a known technique (not shown). This rotation is transmitted to the drive pulley IJ19, the belt 17, and the driven pulley 18 fixed to the drive roller 1G, and as the drive roller 16 rotates, the paper storage helt 14 rotates in the direction of the arrow. The direction of rotation of this paper storage belt 14 is determined by the discharge roller 13.
This is the direction perpendicular to the direction in which copy paper P is ejected.

FIG. 2 is a side view of the copying machine, centering on the ejector unit of the {th embodiment], and 21 is the operation surface (front) of the main body 1.
