<p>PURPOSE: To prevent a bin tray from deflection due to weight applied on bin rollers positioned on a lead cam. CONSTITUTION: Projecting parts 44a1 are provided on bin rollers 44a at their upper sides provided at the basic end parts of a bin B at the opposing sides. Recessed parts 44a2 are provided on lower sides. When the bin B is stacked, the recessed and projecting parts 44a1, 44a2 of the bin rollers 44a are locked with one another. Thus, weight applied on the bin rollers 44a at opposing bin ends positioned on a lead cam 51 is reduced owing to pushing-up force, using locking with the recessed and projecting parts 44a1, 44a2, resulting in preventing the bin B from deflection and enhancing sheet loading.</p> |
