Abstract:
A document sheet transportation device includes a feeding portion which feeds a document sheet from a document sheet placement portion toward a document sheet transportation path. The feeding portion includes a holder, a feeding member, a supporting body supported by the holder, a rotatable stopper member having a contact end portion allowed to contact a front end of a document sheet, and a biasing member which applies a biasing force to the stopper member. The stopper member is allowed to change a position among a first position in which the contact end portion contacts the front end of the document sheet, a second position which allows feeding of the document sheet by the feeding member, and a third position which is rotated in the first rotating direction from the second position. The biasing member applies the biasing force to the stopper member in a reverse second rotating direction.

Claim (Index 1):
A document sheet transportation device comprising:\n a document sheet placement portion on which a document sheet is placed; a document sheet transportation path provided to extend from the document sheet placement portion to form a transportation path of the document sheet; and a feeding portion which feeds the document sheet toward the document sheet transportation path, wherein the feeding portion includes:\n a holder; \n a feeding member rotatably supported by the holder to feed the document sheet along a predetermined first direction; \n a supporting body which has a first shaft portion and is supported, in the holder, at an upstream side of the feeding member in the first direction; \n a stopper member which has a contact end portion allowed to contact a front end of the document sheet in the first direction, the document sheet being placed on the document sheet placement portion, which is rotatably supported around the first shaft portion by the supporting body, and which regulates feeding of the document sheet by the feeding member by contact of the contact end portion with the front end of the document sheet; and \n a biasing member which applies a biasing force around the first shaft portion to the stopper member, \n the stopper member is allowed to change a position among a first position, a second position, and a third position,\n the first position being a position in which the contact end portion contacts the front end of the document sheet, \n the second position being a position in which the contact end portion is separated from the front end of the document sheet to face the first direction, thereby allowing feeding of the document sheet by the feeding member, and \n the third position being a position in which the contact end portion rotates, from the second position, in a first rotating direction around the first shaft portion to face a second direction reverse to the first direction, and \n the biasing member applies the biasing force to the stopper member in a second rotating direction reverse to the first rotating direction around the first shaft portion.
