ABSTRACT:
Provided in a first embodiment of the invention is a writing implement having built-in illumination which includes a tubular pen body dimensioned to contain a small battery in contact with a terminal lightbulb. The lightbulb is held in place axially in the pen body typically by a corrugated metal bulb holder and by a translucent spacer extending to the end of the pen body where a marking element is located and opposite the end disposed to contain the battery. A metal spring-clip having a sliding portion mounted externally to the pen body is attached through the pen body wall and is disposed to make electrical contact with the battery therein. The sliding portion is free to slide down the exterior of the pen body wall and to make contact with the bulb holder through a hole in the pen body wall, thereby completing the circuit between the bulb and the battery using the length of the spring-clip as a primary conductive element in the system. Provided in a second embodiment is a writing implement having a built-in illumination system which is specially adapted for mounting to a surface such as a clipboard.
