<p>PROBLEM TO BE SOLVED: To arrange many pieces of sheet in order with precision by constituting a discharge tray member by an energizing means which supports a sheet loading member side in such a manner that it can travel freely in the vertical direction and energizes a bottom plate part upward and a regulation means which regulates energization in the upward direction of the energizing means at a fixed position. SOLUTION: A sheet 41 introduced through an introduction port 42 of a sheet post-treatment device main body 40 is conveyed on a sheet loading member 45 through guide members 43, 44 and a conveying roller 46. The sheet 41 is loaded in a condition in which a tip fringe thereof is in contact with a reference fence 47 and is loaded in a condition in which a rear end part thereof rides over a discharge tray 59. This discharge tray 59 consists of a bottom plate part 100 in which the sheet loading member 45 side is supported in such a manner that it can travel freely in the vertical direction, a spring 104 which energizes the bottom plate part 100 upward, and a set clamp 106 which regulates the energization in the upward direction of the spring 104 at a fixed position. Consequently, a top face of the sheet 41 is set to a fixed position at all times.</p> |
