An image sensing apparatus reliably indicates an image sensing area regardless of the size of an object. In the apparatus, illumination units 14 irradiate spot lights 36 on a base 7 to indicate an image sensing area 37 for sensing an original 6 by a camera head 9. The image sensing area indicated by the spot lights 36, irradiated from laser devices 33 of the illumination units 14, attached to the camera head 9, is corresponding to the length/width ratio of the image screen of a monitor 3. A luminance signal level, stored in a memory of a system controller 15, on image sensing the base, is compared with the level of a luminance signal from an image sensing device 25, and when the signal levels do not coincide, it is determined that an original exists on the base. Further, the system controller 15 independently changes first to fourth spot lights 110 to 113 irradiated from the first to fourth illumination units.
