Claims

[Scope of Claim for Utility Model Registration] (1) An upper cover that covers the document table on the top surface of the device body is rotatably provided around one end of the top surface of the device body, and a light source is provided on the top cover to illuminate the document on the document table. and a first mirror that forms an angle of 45° with respect to the document table when the upper cover is closed, the document-side optical unit is provided movably in the direction of connection between the upper cover and the main body of the apparatus, and the center of rotation of the upper cover is A second mirror is provided near the position to reflect downward the document image light parallel to the upper cover reflected by the first mirror, and the document reflected by the second mirror is provided on the apparatus main body side. A third mirror is provided to reflect the image light, and a light receiving unit is provided on the main body side of the apparatus, and includes a lens that forms an image of the document image light reflected by the third mirror, and an optical sensor disposed at the image forming position. An image input device characterized in that it is provided to move in conjunction with the original document side optical unit. (2) The document table of the apparatus main body is constructed of a transparent plate, and a light source is provided below the document table, facing the first mirror, and irradiates light onto the document on the document table from below, and 2. The image input device according to claim 1, wherein the image input device is provided so as to be interlocked with the first mirror while facing the first mirror. (3) Claim 1 characterized in that the upper surface of the upper cover is composed of a semi-transparent plate or a half mirror.
The image input device described. (4) The second mirror is provided so as to be rotatable about the rotation center of the upper cover, and
Claim 1, further comprising a mirror rotation mechanism that rotates the mirror by an angle half the rotation angle of the upper cover in conjunction with the rotation of the upper cover.
The image input device described.
