Abstract
In a sheet storage apparatus having a plurality of bin trays for stacking sheets fed sequentially from an image forming device into sheaves of sheets, sheet accommodating spaces formed on the respective bin trays for receiving the sheets fed from the image forming device are made wide at a sheet intake position so as to successfully introduce the sheets thereinto and narrow at the positions above and below the sheet intake position so as to effectively store the sheets. When the sheets introduced into the sheet accommodating space at the sheet intake position comes to a prescribed number or height, the bin trays are moved upward or downward to narrow the sheet accommodating spaces, thus to compress a bulky stack of sheets. When taking out the finished sheaves of sheets from the apparatus, the sheet accommodating spaces formed between the bin trays are made relatively wide.
