Claims

[Claims for Utility Model Registration] 1. A bar-shaped light source lamp and a gutter-shaped reflecting mirror surrounding it form a belt-shaped illumination area on the surface on which the original is placed, and is held by a bottom plate and a pair of side plates. In a document illuminating device that uses a self-occurring lens array to project light from the illumination area onto a photoreceptor, the side plate is formed with an opening for holding the self-occurring lens array, with the bottom plate serving as a reference surface on the device side;
A mounting portion of a self-occurring lens array having reference surfaces formed on the lower surfaces of the mounting portions at both ends is inserted into the opening, and a substantially U-shaped spring is interposed in the gap between the upper edge of the opening and the mounting portion. A document illuminating device characterized in that the self-occurring lens array is fixed by pressing the reference surface of the self-occurring lens array against a bottom plate, which is an apparatus-side reference surface, by the elastic force of the spring. 2. A bar-shaped light source lamp and a gutter-shaped reflector surrounding it form a belt-shaped illumination area on the surface on which the document is placed, and the illumination area is illuminated by a self-occurring lens array held by a pair of side plates. In the document illumination device for projecting light from a photoreceptor onto a photoreceptor, an opening is formed in the side plate, the lower edge of which is a reference edge on the device side, and reference surfaces are formed on the lower surfaces of attachments at both ends of the self-occurring lens array. , the mounting part is inserted into the opening, and a substantially U-shaped spring is interposed in the gap between the upper edge of the opening and the mounting part,
A document illuminating device characterized in that a self-occurring lens array is fixed by pressing the reference edge and the reference surface into contact with each other by the elastic force of the spring. 3. The document illumination device according to item 1 or 2, wherein the spring has a slip-off prevention mechanism that engages with the side plate.
