Sheet storage device and image forming system

Abstract

The present invention provides a sheet storage device and an image forming system capable of classifying stored sheets while avoiding enlargement of the image forming device. A structure in which each time the stapled sheet bundle on the swing tray is stapled, the stapled sheet bundle is transferred to the front tray on the front side of the device, and the stack is stored on the front tray , for the sheet stack of the first volume, it is transported to the first position where its rear end reaches the position (α) before being transported to the front tray, and then the sheet stack of the first volume at the first position is stacked toward Front pallet transfer. Then, the sheet stack of the next second volume is conveyed to the second position where the rear end reaches the position (β) on the downstream side in the X direction from the position (α) before being transferred to the front tray, After that, the sheet bundle of the second volume at the second position is transferred toward the front tray.

Description

technical field [0001] The present invention relates to a sheet storage device for storing sheets discharged from an image forming apparatus, and an image forming system including the image forming apparatus and the sheet storage device. Background technique [0002] In an image forming apparatus such as a copying machine, a sheet storage unit for storing image-formed sheets discharged from the image forming unit is generally arranged. [0003] Patent Document 1 discloses a configuration in which, as the sheet storage unit, a discharge tray for storing sheets discharged from the image forming unit is provided, and the sheets stored in the discharge tray are oriented in a direction parallel to the discharge direction. Conveyor belt for delivery. [0004] In this structure, control is performed such that when all the sheets after image formation for one job are stored in the discharge tray, the direction of stacking the sheets on the discharge tray is parallel to the discharg...

AI Technical Summary

Problems solved by technology

[0008] This is because the smaller the height of the sheet storage space, the smaller the maximum number of sheets that can be stacked and stored on the discharge tray, and it is difficult for the user to insert the hand into the sheet storage space to take out the stack and store it on the discharge tray. Removal operation when stacking sheets in the paper tray

[0009] Although it is better to increase the height of the sheet storage space, it is not preferable because the dimension in the height direction of the image forming apparatus becomes large, resulting in an increase in the size of the image forming apparatus.
