Paper feed cassette

Abstract

A paper feed cassette includes a second press member for pressing the center in a width direction of an upper surface of a paper. The second press member integrally includes a flat portion mounted on the lower surface of the lid member, an inclined portion integrally bonded with the flat portion on a region other than an end in a lower surface of the flat portion, extending in an oblique direction toward an inner bottom surface of the cassette body, and having at least an elastically deformable bonding portion between the inclined portion and the flat portion and a press portion provided on a forward end of the inclined portion, and the press portion is brought into contact with the inner bottom surface of the cassette body when the lid member is arranged on the upper portion of the cassette body.

1 . A paper feed cassette comprising:
 a cassette body mounted on an image generating apparatus including a paper feed roller and storing a paper;   a first press member provided on at least a first side surface inside said cassette body and pressing a side surface of said paper when said paper is stored;   a lid member arranged on an upper portion of said cassette body; and   a second press member provided independently of said lid member, mounted on a lower surface of said lid member, and pressing the vicinity of the center in a width direction of an upper surface of said paper stored in said cassette body, wherein   said second press member integrally includes:   a flat portion mounted on said lower surface of said lid member,   an inclined portion integrally bonded with said flat portion on a region other than an end in a lower surface of said flat portion, extending in an oblique direction toward an inner bottom surface of said cassette body, and having at least an elastically deformable bonding portion between said inclined portion and said flat portion, and   a press portion provided on a forward end of said inclined portion, and   said press portion is brought into contact with said inner bottom surface of said cassette body when said lid member is arranged on said upper portion of said cassette body.   
   
   
       2 . The paper feed cassette according to  claim 1 , wherein
 said press portion is so formed as to have a substantially L-shaped section and linearly press said paper with a corner of said L-shape.   
   
   
       3 . The paper feed cassette according to  claim 1 , wherein
 said flat portion of said second press member is mounted on said lower surface of said lid member with an adhesive layer.   
   
   
       4 . The paper feed cassette according to  claim 1 , wherein
 said inclined portion is bonded at the substantial center of said flat portion.   
   
   
       5 . The paper feed cassette according to  claim 1 , wherein
 said flat portion of said second press member includes a first flat portion on the right and a second flat portion on the left, between which a bonding line between said flat portion and said inclined portion is a boundary line, and   said second flat portion is formed by providing a U-shaped cutout portion in a prescribed region of a bonding portion between said first flat portion and said inclined portion and folding back an inner region of said U-shaped cutout portion of said first flat portion along said bonding line of said bonding portion.   
   
   
       6 . The paper feed cassette according to  claim 8 , wherein
 said second press member includes a support portion integrally coupled with said first flat portion on an end of said first flat portion, extending in an oblique direction toward said inclined portion, and supporting said inclined portion.   
   
   
       7 . The paper feed cassette according to  claim 1 , wherein
 said bonding portion between said inclined portion and said flat portion of said second press member is so formed as to have a thickness larger than those of said inclined portion and said flat portion.   
   
   
       8 . The paper feed cassette according to  claim 1 , wherein
 said second press member is mounted on said lower surface of said lid member such that said inclined portion of said second press member is inclined from said bonding portion between said inclined portion and said flat portion toward a direction opposite to a paper feed direction of said paper.   
   
   
       9 . The paper feed cassette according to  claim 5 , wherein
 an engaging portion engaging with said flat portion of said second press member is integrally provided on said lower surface of said lid member.   
   
   
       10 . The paper feed cassette according to  claim 1 , wherein
 said press portion of said second press member is so formed as to be arranged substantially on a line of action of pressing force in pressing said paper with said first press member in plan view.   
   
   
       11 . A paper feed cassette comprising:
 a cassette body mounted on an image generating apparatus including a paper feed roller and storing a paper;   a lid member arranged on an upper portion of said cassette body;   a first press member provided on at least a first side surface inside said cassette body and pressing a side surface of said paper when said paper is stored; and   a second press member provided independently of said lid member, mounted on a lower surface of said lid member, and pressing the vicinity of the center in a width direction of an upper surface of said paper stored in said cassette body, wherein   said second press member integrally includes:   a flat portion mounted on said lower surface of said lid member,   an inclined portion integrally bonded with said flat portion on a region other than an end in a lower surface of said flat portion, extending in an oblique direction toward an inner bottom surface of said cassette body, and having at least an elastically deformable bonding portion between said inclined portion and said flat portion, and   a press portion provided on a forward end of said inclined portion,   said press portion is brought into contact with said inner bottom surface of said cassette body when said lid member is arranged on said upper portion of said cassette body,   said press portion is so formed as to have a substantially L-shaped section and linearly press said paper with a corner of said L-shape,   said flat portion of said second press member is mounted on said lower surface of said lid member with an adhesive layer, and   said inclined portion is bonded at the substantial center of said flat portion.   
   
   
       12 . The paper feed cassette according to  claim 11 , wherein
 said bonding portion between said inclined portion and said flat portion of said second press member is so formed as to have a thickness larger than those of said inclined portion and said flat portion.   
   
   
       13 . The paper feed cassette according to  claim 11 , wherein
 said second press member is mounted on said lower surface of said lid member such that said inclined portion of said second press member is inclined from said bonding portion between said inclined portion and said flat portion toward a direction opposite to a paper feed direction of said paper.   
   
   
       14 . The paper feed cassette according to  claim 11 , wherein
 an engaging portion engaging with said flat portion of said second press member is integrally provided on said lower surface of said lid member.
