Sheet storage cassette and image forming apparatus

Abstract

A sheet storage cassette can include a sheet supporting board and a restriction guide. The sheet supporting board can support at least one sheet thereon. The restriction guide can be arranged on the sheet supporting board and include a sheet holding surface that is substantially perpendicular to the sheet support board. The restriction guide can further include a mark indicated part at an upper side thereof, where the mark indicated part can extend at least partly along a plane that intersects a plane of the holding surface and can indicate a maximum storage capacity level of the sheet storage cassette.

1 . A sheet storage cassette, comprising:
 a sheet supporting board configured to support at least one sheet thereon; and   a restriction guide arranged on the sheet supporting board and including a sheet holding surface substantially perpendicular to the sheet supporting board;   wherein the restriction guide includes a mark indicated part at an upper side thereof, the mark indicated part extending at least partly along a plane that intersects a plane of the sheet holding surface, and indicating a maximum storage capacity level of the sheet storage cassette.   
     
     
         2 . The sheet storage cassette of  claim 1 , wherein the mark indicated part includes a plane. 
     
     
         3 . The sheet storage cassette of  claim 1 , wherein the mark indicated part includes an inclined surface that inclines toward the sheet holding surface. 
     
     
         4 . The sheet storage cassette of  claim 3 , wherein an angle between the mark indicated part and an upper surface of the sheet supporting board is an obtuse angle. 
     
     
         5 . The sheet storage cassette of  claim 4 , wherein the angle is between 110° and 150°, inclusive of 110° and 150°. 
     
     
         6 . The sheet storage cassette of  claim 1 , wherein the mark indicated part is arranged at a level of a maximum storage capacity of the sheet storage cassette. 
     
     
         7 . The sheet storage cassette of  claim 1 , wherein the sheet storage cassette includes a plurality of the restriction guides. 
     
     
         8 . The sheet storage cassette of  claim 1 , wherein the sheet storage cassette includes a pair of restriction guides that face toward each other. 
     
     
         9 . An image forming apparatus, comprising:
 a sheet storage cassette according to  claim 1 .
