<p>PURPOSE:To secure sufficient space between bins and to prevent the generation of frictional sound by providing the side portion of a bin with a link mechanism for supplementarily expanding a space between the bin and the lower bin with the upward movement of the sheet introducing side of the bin. CONSTITUTION:A plurality of bins 2 can be sequentially moved up and down by bin up-and-down moving means 3. The first connecting member 41 is projected on the side portion of each bin 2 except the lowermost bin, and the second connecting member 42 is projected on each bin 2 except the uppermost bin 2. Longitudinal and lateral slots 41a, 42a are respectively formed on both connecting members 41, 42, and the upper connecting member 41 and the lower connecting member 42 are engaged with each other in such a manner as to freely move up and down by pins of connecting arms 43 in the slots. Accordingly, when the introducing sides of the upper and lower bins 2 are expanded by the bin up-and-down moving means 3, the space between the bin 2 and the lower bin 2 is supplementarily expanded by action of a link mechanism comprising links 41, 42, 43 to avoid sliding between bins and prevent the generation of frictional sound.</p> |
