Claims

[Scope of utility model registration request]

(1) In a document reading device that transports a document and optically reads and scans the surface to be read of the document at a predetermined position on the document transfer path using a reading section, the device is disposed immediately before the document reading position in the document transfer path. a guide provided therein to restrict deviation of the original toward the reading section; and a rear surface arranged to face the guide with a minimum facing interval defined and rotated in synchronization with the transport operation of the original. A variable interval is provided on at least one of the roller, the guide and the back roller and shifts the position of the guide or the back roller in the direction of the thickness of the document depending on the thickness of the document being transferred to vary the mutual facing distance. A document reading device characterized by comprising a mechanism.

(2) The variable interval mechanism is provided on the back roller and shifts the position of the back roller in the thickness direction of the document depending on the thickness of the document.Claim (1) of the Utility Model Registration Claim: The manuscript reading device described.

(3) The document according to claim 1, wherein the variable interval mechanism is provided in the guide and deviates the position of the guide in the thickness direction of the document according to the thickness of the document. reading device.
