<p>PROBLEM TO BE SOLVED: To appropriately hold a reflection member which performs reflection multiple times, so as to suppress vibration of the reflection member without enlarging the reflection member when positioning and holding the reflection member.SOLUTION: In a reading unit 4 in which an illumination member 5, a plurality of reflection members 9-13, an image forming member 7 and an imaging device 6 are packaged, when positioning and holding the reflection members 10 and 11 which reflect reflection light 8 from a document 2 multiple times, with support members 41 and 42 including three abutting parts 41a, 42a and 43a abutted to one side of the reflection member and a pressing member 43 pressing the reflection member to the three abutting parts from a surface at an opposite side to a surface to which the abutting parts are abutted, at least one of the three abutting parts is disposed inside of a length direction end portion of a reflection area 8a with a maximum length in a length direction in the reflection member.</p> |
