A device for changing a light bulb comprising an outer tube and an inner tube positioned inside the outer tube, wherein the tubes are adjustable along a longitudinal axis. A spacer film exhibiting a tensile stress characteristic is deposited over the gate electrode. An adhesion increasing film is formed between the insulating layer, and at least one of the semiconductor constructing body and the base member around the semiconductor constructing body, for preventing peeling between the insulating layer and the at least one of the semiconductor constructing body and base member. The surface illuminator provides a tape surface located by the tape guide in a manner that allows the imager to capture images for characterization by the image processor.
