。 A point light source having a long lamp sealing body, an optical system member that collimates the diffused irradiation light from this point light source, and a condenser that focuses the light passing through this optical system member in a slit shape on the document surface. In the document illuminating device, the point light source is disposed vertically, and the document illumination device is configured to sequentially illuminate the document surface in a slit shape by relatively moving the document surface or the condensing member. A first mirror that reflects light from the light emitting section in the vertical direction is disposed at a position corresponding to the light emitting section of the shaped light source, and a second mirror is disposed at a position opposite to the first mirror. A document illuminating device characterized in that the optical axis of the irradiated light from the point light source is appropriately deviated in the vertical direction.
