PROBLEM TO BE SOLVED: To provide a sheet housing device capable of sorting sheets that are housed while avoiding increase in size of an image formation device.SOLUTION: Each time a sheet bundle Sb on a swing tray 22 is bound with a staple, the sheet bundle Sb, after being bound with the staple, is transferred to a front surface tray 51 on a device front surface side so that it is loaded and housed on the front surface tray 51. For the sheet bundle sb of a first copy, before being transferred to the front surface tray 51, it is transported to a first position where its rear end Se reaches a position α, and then, the sheet bundle Sb of the first copy existing at the first position is transferred to the front surface tray 51. Then, for the sheet bundle Sb of a second copy, before being transferred to the front surface tray 51, it is transported to a second position where its rear end Se reaches a position &bgr; on a lower stream side in X direction than the position α, and then, the sheet bundle Sb of the second copy existing at the second position is transferred to the front surface tray 51. |
