Conveyance apparatus

Abstract

A conveyance apparatus includes: a pair of rollers configured to convey a medium while nipping the medium; a nip guide configured to hold one roller between the pair of rollers and guide the medium toward the pair of rollers; and an elastic body configured to bias the nip guide and the one roller such that the one roller is pressed against the other roller between the pair of rollers, wherein the nip guide includes a guide plate that spreads in a width direction of the medium and a conveyance direction of the medium and guides the medium toward the pair of rollers.

What is claimed is: 
     
         1 . A conveyance apparatus comprising:
 a pair of rollers configured to convey a medium while nipping the medium;   a nip guide configured to hold one roller between the pair of rollers and guide the medium toward the pair of rollers; and   an elastic body configured to bias the nip guide and the one roller such that the one roller is pressed against the other roller between the pair of rollers,   wherein the nip guide includes a guide plate that spreads in a width direction of the medium and a conveyance direction of the medium and guides the medium toward the pair of rollers.   
     
     
         2 . The conveyance apparatus according to  claim 1 ,
 wherein the guide plate enters a space between the pair of rollers.   
     
     
         3 . The conveyance apparatus according to  claim 2 ,
 wherein the guide plate spreads in the conveyance direction in the space between the pair of rollers by a length equal to or longer than a half of a length in the conveyance direction in the space to a nip area where the pair of rollers nips the medium.   
     
     
         4 . The conveyance apparatus according to  claim 1 ,
 wherein the guide plate spreads over an entire region of the one roller in the width direction.   
     
     
         5 . The conveyance apparatus according to  claim 1 ,
 wherein the one roller is a driven roller,   the conveyance apparatus further comprises a roller shaft that supports the driven roller, and   the nip guide includes a pair of support portions in which both ends of the roller shaft in the width direction are inserted in a direction opposite to the conveyance direction and which support the both ends.
