Sheet storage apparatus and image formation system using the apparatus

摘要

To provide a sheet storage apparatus for enabling sheets that are carried out of an image formation apparatus or the like on the upstream side to be loaded and stored in a predetermined position with a correct posture neatly at high speed, a sheet discharge roller and a reverse roller spaced a distance are disposed in a sheet discharge outlet and a tray, a kick member is provided to be swingable in a vertical direction passing a sheet discharge path of a sheet discharged from the sheet discharge outlet, and a posture of the kick member is controlled by shift means. The shift means controls the kick member among a waiting posture retracted upward from the sheet discharge path, an engagement posture for imposing a load on the sheet to engage, and an actuation posture dropping onto the tray together with the sheet.

主权项

1. A sheet storage apparatus, comprising:
a sheet discharge outlet for carrying out a sheet sequentially; a placement tray disposed in a level difference formed on a downstream side of the sheet discharge outlet to place the sheet dropped from the sheet discharge outlet; a sheet discharge rotating body disposed in the sheet discharge outlet; a reverse rotating body capable of moving up and down between an actuation position for engaging the sheet on the placement tray and a retracted position retracted upward to switch a transport direction of the sheet; an alignment rotating body that aligns the sheet dropped from the sheet discharge outlet to a predetermined position on the placement tray; and a kick member disposed between the sheet discharge rotating body and the reverse rotating body to forcibly drop a sheet rear end carried out of the sheet discharge outlet toward the alignment rotating body positioned downward, wherein the kick member is configured to swing among a waiting posture retracted upward from the sheet carried from the sheet discharge outlet to the reverse rotating body, an engagement posture for imposing a load on the sheet nipped by each of the sheet discharge rotating body and the reverse rotating body, and an actuation posture for forcibly dropping the sheet rear end released from the sheet discharge rotating body by a weight of the kick member freely falling, the kick member is coupled to a shift member for changing from the waiting posture to the engagement posture, and the shift member is provided with an engagement portion for holding the kick member in the waiting posture, while changing from the actuation posture to the waiting posture.
