Sheet storage device and sheet processing apparatus using such device

摘要

A sheet storage device includes a sheet tray, two guide plates and a width adjusting mechanism. The sheet tray supports a sheet. The two guide plates, disposed on the sheet tray, guides transportation of the sheet placed on the sheet tray. The width adjusting mechanism, disposed on the sheet tray and connected to the two guide plates, adjusts a distance between the two guide plates. The width adjusting mechanism includes a pinion, a resilient member, a toothed portion and two connectors. The pinion is rotatably disposed. The resilient member is disposed coaxially with and rotated with the pinion. The toothed portion is disposed around the resilient member and in contact with the resilient member. The toothed portion provides a resisting force upon rotation of the pinion. Each connector connects the pinion to one of the guide plates.
