Abstract
An apparatus for storing unused felt pens for use in an electronic input board system includes a plurality of pen loaders. In systems in which multiple color information is written on the electronic board, colored felt pens are provided and one of these color felt pens is replaceably mounted in a pen holder. In order to prevent drying out of ink, the unused felt pens are sealed with a cap which is positioned within each pen loader. When a felt pen is loaded into the pen holder to write a letter or a graphic pattern of a selected color, a switch detects which felt pen has been selected for loading in the pen holder, and the system identifies the color of the pen. The apparatus maintains the points of unused felt pens airtightly sealed within the cap to protect them against drying out of ink, while allowing a single-handed operation for loading/unloading a felt pen into/from the pen holder without staining the operator's fingers, clothes, etc. with ink.
