録請求の範囲第１記載の画像読取装置。[Claims for Utility Model Registration] (1) A device comprising a light-emitting section that emits light toward a sheet of paper on which an image is written, and a light-receiving section that receives light reflected from the sheet, and that reads the image of the sheet set at the reading position. an image reading head for reading; a first supporting member that supports the paper from the image reading head side to create a certain gap between the image reading head and the paper; and a first supporting member that approaches and moves away from the first supporting member. a reference that is capable of contacting the paper from a side opposite to the first support member, supports the paper in cooperation with the first support member, and has a reference reflectance at a position facing the reading head; In an image reading device including a second support member having a reflective surface, when the paper is not present between the first support member and the second support member, the reading surface of the reading head and the A blocking member is provided at a position that blocks the space in which the reference reflective surface faces each other with a gap therebetween from the outside, and retreats to a position that allows the paper to pass when the paper passes between the support members. An image reading device characterized by: (2) When the first support member and the second support member do not have the paper between them, the first support member and the second support member are mutually aligned on both the upstream and downstream sides of the reading surface and the reference reflective surface in the paper feeding direction. The image reading device according to claim 1, which is in close contact with the user and functions as the blocking member.
