<p>PROBLEM TO BE SOLVED: To prevent a sheet bundle end part from forming a wedge shape to improve arrangement accuracy, by setting an angle of a paper discharge tray having two tilted surfaces between a tilted surface, near to a rising part and the rising part of the other tilted surface into larger than a right angle. SOLUTION: A paper discharge tray, fitted to the paper discharge part of a picture image forming device, has a rising part 1, for supporting a paper, discharged on a lower end side to be freely dropped, and a tilted surface 2 composed of first and second tilted surfaces 2a and 2b. In this case, the setting is made so as to satisfy the relation ofψ2 >ψ1 , whereψ1 andψ2 : the respective tilted angles of the first and second tilted surfaces 2a and 2b. Also, an angleθ1 , formed of the rising part 1 and the first tilted surface 2a, is made larger than a right angle, and an angleθ2 , formed of the rising part 1 and the second tilted surface 2b, is made a right angle. Consequently, when many sheets are stacked along the tilted surface 2, the angle, formed of a sheet bundle and the rising part 1, can be formed nearly the right angle, thereby correctly and properly arranging the sheet end surfaces instead forming a wedge shape.</p> |
