Medium feeding apparatus and image reading apparatus

Abstract

A medium feeding apparatus includes a curved path that is a medium feeding path formed between a first pair of feeding rollers and a second pair of feeding rollers. The medium is transported along the curved path while being curved downward. The medium feeding apparatus further includes an accommodating portion formed outside a curve of the curved path and configured to accommodate a deformed part of the medium at the curved path. The first pair of feeding rollers is provided at a center area in a medium width direction intersecting with a medium feeding direction. The accommodating portion has a pushing member configured to push the deformed part of the medium upstream in the medium feeding direction.

What is claimed is: 
     
         1 . A medium feeding apparatus, comprising:
 a first pair of feeding rollers configured to feed a medium downstream;   a second pair of feeding rollers provided downstream of the first pair of feeding rollers;   a curved path that is a medium feeding path formed between the first pair of feeding rollers and the second pair of feeding rollers, the medium being transported along the curved path while being curved downward; and   an accommodating portion formed outside a curve of the curved path and configured to accommodate a deformed part of the medium at the curved path; wherein   the first pair of feeding rollers is provided at a center area in a medium width direction intersecting with a medium feeding direction, and wherein   the accommodating portion has a pushing member configured to push the deformed part of the medium upstream in the medium feeding direction.   
     
     
         2 . The medium feeding apparatus according to  claim 1 , wherein
 the pushing member is an elastic member whose downstream portion in the medium feeding direction is fixed and whose upstream portion in the medium feeding direction pushes the deformed part of the medium.   
     
     
         3 . The medium feeding apparatus according to  claim 1 , wherein
 the pushing member is a pivot member that has a pivot at a downstream portion in the medium feeding direction, and an upstream portion located upstream of the pivot in the medium feeding direction pushes the deformed part of the medium.   
     
     
         4 . The medium feeding apparatus according to  claim 1 , wherein
 the pushing member is provided at a center area in the medium width direction.   
     
     
         5 . The medium feeding apparatus according to  claim 1 , further comprising:
 a controller configured to control the first pair of feeding rollers and the second pair of feeding rollers; wherein   the controller changes an amount of driving the first pair of feeding rollers depending on feeding conditions when the first pair of feeding rollers is driven, with the second pair of feeding rollers stopped.   
     
     
         6 . An image reading apparatus, comprising:
 a reader configured to read a medium; and   the medium feeding apparatus according to  claim 1  configured to feed the medium toward a reading position where the medium is read by the reader.
