Claims

[Scope of utility model registration request]

A reading means for reading a document at a reading position, a guide means for guiding the document to the reading position, and a pair of rollers provided in the middle of a document conveyance path formed by the guide means for conveying the document. The pair of rollers are arranged so that the tangent at the engagement point of both rollers is in a direction different from the conveying direction of the document sent from upstream, and furthermore, at least one of the pair of rollers A document reading device characterized by comprising an elastic ring that normally protrudes from the outer surface of the roller, but can be deformed to be flush with the outer surface of the roller by compression.
