Claims

[Scope of Claim for Utility Model Registration] (1) A first manuscript table arranged to fixedly place a first manuscript, and a second manuscript table arranged to be horizontally movable on which a second manuscript is placed. a second document table; and a first reflecting mirror arranged to reflect light from a first document placed on the first document table into a first optical path parallel to the surface of the first document. Then, the light traveling in the first optical path described above is reflected as light traveling in a second optical path parallel to this first optical path and in the opposite direction to the traveling direction of the light emitted from the first reflecting mirror. a second reflecting mirror and a third reflecting mirror having magnetic members arranged to
an exclusion means arranged to exclude the second reflecting mirror from the first optical path by horizontally moving the reflecting mirror;
The image forming lens is arranged to form an image on the image sensor, and the image of the first document placed on the first document table is transmitted through the first, second, and third reflecting mirrors. When an image is formed on the line image sensor by the imaging lens, the second reflecting mirror is held by a magnetic member having the second reflecting mirror and a magnetic member fixed on the other side. An image reading device characterized in that: (2) A first and second document table on which a document is placed and arranged so as to be movable in the horizontal direction, and a light beam from the document placed on the first document table is parallel to the surface of the document. a first reflecting mirror disposed to reflect the light traveling in the first optical path; A second reflecting mirror and a third reflecting mirror each having a magnetic member arranged to reflect light traveling in a second optical path in a direction opposite to that of comprising an excluding means disposed to exclude the reflecting mirror from the first optical path, and an imaging lens disposed so as to image the light traveling in the second optical path on the line image sensor; The image of the document placed on the first document table is transferred to the first, second and third document table.
When forming an image on the line image sensor by the imaging lens through the reflecting mirror, the second reflecting mirror is a magnetic member having the second reflecting mirror, and a magnetic material fixed on the other side. An image reading device characterized in that the image reading device is held by a member.
