IMAGE READING DEVICE AND IMAGE FORMING APPARATUS INCLUDING THE SAME

摘要

An image reading device includes a scanner casing fixed to an upper side of a body frame of an image forming apparatus body, a document pressing member that covers an upper surface of the scanner casing, a leg part provided to be movable with respect to the scanner casing in a vertical direction, a stationary part fixed to an upper end of the leg part, a rotating part connected rotatably to the stationary part via a hinge shaft and supporting the document pressing member, a holding mechanism to hold an opening angle of the document pressing member, and cylindrical parts, passing through the scanner casing in the vertical direction, and having lower end portions fixed to the body frame. The leg part is inserted into the cylindrical part from an upper end opening of the cylindrical part and inclined to a side of the document pressing member.

主权项

1. An image reading device comprising:
a scanner casing provided on an upper surface thereof with a contact glass on which a document is placed, and fixed to an upper side of a body frame of an image forming apparatus body; an image reading unit accommodated in the scanner casing and optically reads an image of the document on the contact glass; a document pressing member that covers an upper surface of the scanner casing so as to be openable and closable; a leg part configured to be movable with respect to the scanner casing in a vertical direction; a stationary part fixed to an upper end of the leg part; a rotating part connected rotatably to the stationary part via a hinge shaft and supporting the document pressing member; a holding mechanism interposed between the rotating part and the stationary part to apply urging force to the document pressing member in an opening direction, thereby holding an opening angle of the document pressing member at an arbitrary angle; and cylindrical parts extending in the vertical direction, passing through the scanner casing in the vertical direction, and having lower end portions fixed to the body frame, wherein the leg part is configured to be inserted into the cylindrical part from an upper end opening of the cylindrical part and to be inclined to a side of the document pressing member in the cylindrical part by a self-weight of the document pressing member.
