Abstract

PURPOSE:To constitute a titled device so that a discharged sheet is matched satisfactorily, by forming an inclined surface part in one corner of a sheet pile up part of a sheet tray for pile up a carried sheet. CONSTITUTION:A sheet piled up in an intermediate tray 7 is loaded by placing a part of the sheet on an inclined surface part 71 formed in one corner of its intermediate tray. This inclined part 71 is a part inclined by an angle theta against a sheet loading part 72. That is to say, the loaded sheet receives force pressed by component of force of dead weight of the sheet in the direction making the opposite angle with its inclined surface part 71, and is placed in order in a state that it has run against an end face 73 and a front face 74 of the intermediate tray.

FIG. 1 is a schematic sectional view of a double-sided copying machine showing an example to which the sheet/lay device of the present invention can be applied. In the figure, sheets 2 stacked on a cassette 1 are fed from a paper feed roller 3, separated by 7η, and then passed through a timing roller 4, a toner image is transferred from a photosensitive drum 5 at a transfer section, and then a fixing roller 6 and then intermediate tray 7.
is stored and loaded. Next, the sheet is fed from this intermediate tray 7 by a feed roller 8, is conveyed to a transfer section via a timing roller 4, passes through a fixing roller 6, and is ejected to a paper ejection tray 9, where toner images are formed on both sides of the sheet. is formed.

In the figure, a single-sided copy sheet 2 is transported in the direction of arrow A by a transport roller 10 and stored in an intermediate tray 7. A portion of the sheets stored in the intermediate tray 7 is placed on a sloped portion 7+ (a portion of the intermediate tray 7 inclined at a constant angle θ with respect to the sheet stacking portion 72) formed at one corner of the intermediate tray. and then loaded.

。The sheets stacked in this state are separated one by one and sent out from the lower side of the intermediate tray 7 by a feeding roller 8. 11 and 12 are conveyance rollers and guides at that time. The sheets stacked in the intermediate tray 7 are fed after being aligned in the intermediate tray 7, so there is no need for any special alignment means. For example, in the case of double-sided copying, the front and back sides of the sheets are You can accurately align the sides.
