Sheet discharging apparatus, sheet finishing apparatus, and image forming apparatus

Abstract

A sheet discharging apparatus including: a sheet discharging section that discharges sheets at a position lower than a height H 0 of 381 mm from a floor surface; and a sheet stacking section, which stacks the sheets discharged from the sheet discharging section, including a sheet raising section which raises the sheets discharged from the sheet discharging section so that a position of a top part of each of the sheets is higher than the height H 0.

1 . A sheet discharging apparatus comprising:
 a sheet discharging section that discharges sheets at a position lower than a height H 0  of 381 mm from a floor surface; and   a sheet stacking section, which stacks the sheets discharged from the sheet discharging section, including a sheet raising section which raises the sheets discharged from the sheet discharging section so that at least a position of a top part of each of the sheets is higher than the height H 0 .   
     
     
         2 . The sheet discharging apparatus according to  claim 1 , wherein the sheet raising section comprises a conveying belt which is inclined so as to convey obliquely upwards the sheets discharged from the sheet discharging section and raise the sheet. 
     
     
         3 . The sheet discharging apparatus according to  claim 2 , further comprising a supporting member which receives the sheets having been raised and supports the sheets in a condition in which the position of the top part of each of the sheets is higher than the height H 0 . 
     
     
         4 . The sheet discharging apparatus according to  claim 3 , wherein the supporting member has a sheet supporting surface which is inclined so that a position of the sheet supporting surface in a downstream side of the conveying direction is higher than a position of the sheet supporting surface in an upper stream side of the conveying direction, wherein the conveying belt and the supporting member are configured to satisfy a condition: θ 1 <θ 2 , where an angle of inclination of the conveying belt to a horizontal surface is θ 1  and an angle of inclination of the sheet supporting surface of the supporting member to the horizontal surface is θ 2 , and the conveying belt conveys the sheets and accumulates the sheets in an inclined condition on the supporting member. 
     
     
         5 . The sheet discharging apparatus according to  claim 2 , further comprising a control section which controls an actuation of the conveying belt so as to actuate the conveying belt on a job end and move the sheets to the supporting member. 
     
     
         6 . A finishing apparatus comprising the sheet discharging apparatus according to  claim 1  and a finishing section which processes the sheets to be conveyed to the sheet discharging apparatus. 
     
     
         7 . The finishing apparatus according to  claim 6  comprising a rising and falling sheet discharge tray which is disposed above the sheet stacking section and is capable of rising and falling. 
     
     
         8 . An image forming apparatus comprising the sheet discharging apparatus according to  claim 1  and an image forming section which forms an image on the sheets to be conveyed to the sheet discharging apparatus.
