FIGS. 7 and 8 , thestandby tray 10 has a pair oftray members tray members standby stoppers - The standby tray 10 slides and moves by the
standby tray motor 34. Between thestandby tray 10 and theprocessing tray 12 where it reaches, when dropping and feeding the sheets of paper P from thestandby tray 10 onto theprocessing tray 12,horizontal matching plates FIG. 9 for preventing the sheets of paper P from turning away in the horizontal direction perpendicular to the conveying direction and matching them horizontally are installed. Thehorizontal matching plates horizontal matching motor 48. - When the gate G is at the second position, the sheets of paper P requiring no post process are fed to second
paper feed rollers 60 and furthermore are fed to thirdpaper feed rollers 61. The secondpaper feed rollers 60 and the thirdpaper feed rollers 61 are respectively composed of upper paper feed rollers 60 a and 61 a and lower paper feed rollers 60 b and 61 b. - A
paper path 63 for leading the sheets of paper P from the entrance rollers, which are branched at the gate G, to the secondpaper feed rollers 60 is installed. Further, between the secondpaper feed rollers 60 and the thirdpaper feed rollers 61, a separate paper path may be installed. The reason is that the sheets of paper P can be conveyed surely. - Under the third
paper feed rollers 61, as mentioned above, the firstpaper ejection tray 16 is arranged. The firstpaper ejection tray 16 receives either of the sheets of paper P which are post-processed and the sheets of paper P which are not post-processed. - Next, the operation of the invention will be described. When an image is formed by the
image forming apparatus 5 and a sheet of paper P is fed from thepaper ejection rollers 6, the sheetpost-process apparatus 7, depending on a case of performing the post-process of the sheet of paper P or a case of performing no post-process, or while the preceding sheet of paper P is in execution of the post-process or the post-process is finished, performs a different operation. - When the post-process is not performed, the sharp-pointed part of the wedge shape of the gate G is at the second position almost pointing the
lower entrance roller 22 b. The sheets of paper P fed from theentrance rollers 22 are fed to the second paper feed rollers and are furthermore fed to the third paper feed rollers. The sheets of paper P fed from the third paper feed rollers are ejected to the firstpaper ejection tray 16. - In this way, on the first
paper ejection tray 16, sheets of paper are sequentially loaded. The firstpaper ejection tray 16 is arranged at a tilt angle of θ 2 and the front end of the sheet of paper is positioned higher than the rear end thereof, so that for example, even if the sheet of paper P is fed to the firstpaper ejection tray 16 in a state that it is curled convexly as shown by a dotted line inFIG. 10 , the preceding sheet of paper P loaded on the firstpaper ejection tray 16 is not pressed out by making contact with the front end of the succeeding sheet of paper P. Namely, the ejected sheet of paper P is sequentially loaded on the firstpaper ejection tray 16 unless the order is disturbed. Even if the preceding sheet of paper P is pressed by the succeeding sheet of paper P and is slightly displaced, since the tilt angle is θ 2, the sheet of paper P drops by its own weight and is loaded on the firstpaper ejection tray 16 with the rear end matched, and the ejection process of the sheet of paper is completed. - Next, a case that the stapling process which is a post-process is to be performed and no preceding sheet of paper P in execution of the stapling process exists on the
processing tray 12 will be described. At this time, thestandby tray 10 slides and moves thetray members FIG. 11 in the directions of arrows m and n and opens the dropping and feeding path of the sheet of paper P. Thehorizontal matching plates paper feed rollers 24 in the horizontal direction, are arranged so that the gap between thehorizontal matching plates paper feed rollers 24, without the conveying being obstructed by thestandby tray 10, is dropped and fed directly onto theprocessing tray 12. - At the time of dropping and feeding, the upper
vertical matching roller 38 a is shifted upward and the receivingportion 44 a of thepaddle 44 receives the rear end of the sheet of paper P. Both sides of the sheet of paper P drop in contact with thehorizontal matching plates paddle 44 rotates in the direction of an arrow o, drops the rear end of the sheet of paper P from the receivingportion 44 a, and beats down it onto theprocessing tray 12 by the beatingportion 44 b. Furthermore, thepaddle 44 feeds the sheet of paper P in the direction of an arrow q by the feedingportion 44 c, and the rear end of the sheet of paper P makes contact with thestopper 45, and the vertical matching of the sheet of paper P is completed. Further, the vertical matching of the sheet of paper P on theprocessing tray 12 may be executed by the uppervertical matching roller 38 a by moving up and down each time. - In this way, the sheet of paper P on which an image is formed is loaded directly on the
processing tray 12 from thepaper feed rollers 24 while sequentially matching it in the horizontal direction and vertically direction. When the sheets of paper P reach a predetermined number, thestapler 14 staples the sheets of paper P on theprocessing tray 12 at a desired position and bundles them to form the paper bundle T. [page 8] Hereafter, the uppervertical matching roller 38 a is moved down onto the paper bundle and the paper bundle T is held between the uppervertical matching roller 38 a rotating in the direction of the arrow r and the lowervertical matching roller 38 b rotating in the direction of the arrow s and is conveyed toward the firstpaper ejection tray 16. When the rear end of the paper bundle T passes the upper and lowervertical matching rollers feed pawl 50 a of theconveyor belt 50 rotating in the direction of the arrow t and is sent onto the firstpaper ejection tray 16. - At this time, the first
paper ejection tray 16 slides and moves from the position indicated by the dashed line inFIG. 3 to the position indicated by the solid line. The firstpaper ejection tray 16 is arranged at a tilt angle of θ 2 and the front end of the sheet of paper is positioned higher than the rear end thereof, so that the preceding sheet of paper P sent onto the firstpaper ejection tray 16 is not pressed out by making contact with the front end of the succeeding paper bundle T. Further, even if the preceding paper bundle T is slightly displaced by the succeeding sheet of paper P, since the tilt angle is θ 2, the paper bundle T drops by its own weight and is loaded on the firstpaper ejection tray 16 with the rear end matched, and the stapling process of the sheets of paper P is completed. - Next, a case that the stapling process which is a post-process is to be performed and preceding sheets of paper P in execution of the stapling process remain on the
processing tray 12 will be described. At this time, thestandby tray 10 slides and moves thetray members FIG. 11 respectively in the opposite direction of the direction of the arrow m or in the opposite direction of the direction of the arrow n, and is moved to the position indicated by the solid line shown inFIG. 11 , and can support the sheet of paper P. Thestandby tray roller 28 is shifted above the standby tray not to disturb the sheets of paper P. The sheets of paper P ejected from theimage forming apparatus 5 and fed by thepaper feed rollers 24 are loaded once on thestandby tray 10 to wait for theprocessing tray 12 to be free. - The sheets of paper P loaded on the
standby tray 10 are moved down onto thestandby tray 10, are sent toward thestandby stoppers standby tray roller 28 rotating in the opposite direction of the direction of the arrow f, and are vertically matched with the rear end of the sheets of paper P in contact with thestandby stoppers paper ejection tray 16 is arranged at a tilt angle ofθ 1 and the front end of the sheets of paper is positioned higher than the rear end thereof, so that the sheets of paper P are vertically matched by the own weight with the rear end thereof in contact with thestandby stoppers - The
standby tray 10 is arranged at a tilt angle ofθ 1, so that for example, even if the sheet of paper P is fed from thepaper feed rollers 24 in a state that it is curled convexly and is fed to thestandby tray 10, the preceding sheet of paper P loaded on thestandby tray 10 is not pressed out by making contact with the front end of the succeeding sheet of paper P. Namely, the fed sheet of paper P is sequentially loaded on thestandby tray 10 unless the order is disturbed. Further, even if the preceding sheet of paper P is pressed by the succeeding sheet of paper P and is slightly displaced, since the tilt angle isθ 1, the sheet of paper P drops by its own weight down to the position where the rear end thereof makes contact with thestandby stoppers standby tray 10 with the rear end matched. - During this period, when the preceding sheet of paper P on the
processing tray 12 is ejected on the side of thepaper ejection tray 16 and theprocessing tray 12 becomes free, thestandby tray 10 slides and moves thetray members FIG. 11 in the directions of the arrows m and n from the position indicated by the solid line inFIG. 11 via the position indicated by the alternate long and short dash line inFIG. 11 . By doing this, for example, two sheets of paper P standing by on thestandby tray 10, when thetray members FIG. 11 , are dropped and fed onto theprocessing tray 12 from between thetray members horizontal matching plates standby tray 10 are controlled on both sides by thehorizontal matching plates - The lower side sheet of paper P of the two sheets of paper P dropped onto the
processing tray 12 is sent in the direction of the arrow q by the lowervertical matching roller 38 b rotating in the opposite direction of the direction of the arrow s, and the rear end of the sheet of paper P makes contact with thestopper 45, and the vertical matching of the sheet of paper P is completed. The upper side sheet of paper P of the two sheets of paper P dropped onto theprocessing tray 12 is sent in the direction of the arrow q by the uppervertical matching roller 38 a rotating in the opposite direction of the direction of the arrow r, and the rear end of the sheet of paper P makes contact with thestopper 45, and the vertical matching of the sheet of paper P is completed, and thereafter, the uppervertical matching roller 38 a is shifted upward. - The third and subsequent sheets of paper P ejected from the
image forming apparatus 5 are directly dropped and fed onto theprocessing tray 12 from between thetray members standby tray 10. Hereafter, the third and subsequent sheets of paper P are sequentially matched on the sheets of paper P loaded earlier on theprocessing tray 12 by thepaddle 44. - When the sheets of paper P loaded on the
processing tray 12 reach a predetermined number, the sheets are stapled by thestapler 14 to form a paper bundle T. Hereafter, the paper bundle T is conveyed toward the firstpaper ejection tray 16 by the upper and lowervertical matching rollers feed pawl 50 a of theconveyor belt 50, and the paper bundle is sent to the firstpaper ejection tray 16, and the stapling process of the sheets of paper P is completed. - In this embodiment having such a constitution, a dedicated path for non-post-process sheets of paper is installed and a sheet post-process apparatus free of reduction in the productivity of the image forming apparatus can be obtained. Furthermore, the time up to paper ejection can be shortened. The paper ejection tray receives either of the sheets of paper P which are post-processed and the sheets of paper P which are not post-processed, so that compared with a case that a non-post-process dedicated paper ejection tray is installed, a great decrease in cost is realized.
- Further, the
standby tray 10 is given a tilt angle ofθ 1, thus the sheets of paper P can be matched by the own weight on thestandby tray 10. There is no fear that the sheet of paper P loaded earlier is pressed out by the succeeding sheet of paper P, and the consistency of the sheets of paper P on thestandby tray 10 can be improved, and the sheets of paper P can be prevented from jamming, and the loading order of the sheets of paper P on thestandby tray 10 can be prevented from disturbance. Similarly, the first or secondpaper ejection tray paper ejection tray paper ejection tray paper ejection tray - Further, in the present invention, as a post-process to be performed for sheets of paper loaded on the processing tray, the stapling process is described. However, the post-process is not limited to a case of stapling sheets of paper and for example, a post-process such as a hole-punching process in sheets of paper is not questionable. In this case, with respect to sheets of paper loaded on the processing tray, loading of one sheet instead of a plurality of sheets of paper provides no trouble. Needless to say, for a post-process apparatus having such a post-processing mechanism, the present invention produces an effect.
- Although exemplary embodiments of the present invention have been shown and described, it will be apparent to those having ordinary skill in the art that a number of changes, modifications, or alterations to the invention as described herein may be made, none of which depart from the spirit of the present invention. All such changes, modifications, and alterations should therefore be seen as within the scope of the present invention.
