Abstract
Abstract A pen holder is adapted to be attached to a spring of a clip-board. The spring has a U-shaped portion. The pen holder has a recess for holding a pen. A notch and a pair of grooves are formed in the base portion for receiving the pivot axle and the legs of the U-shaped portion of the spring. The width of the base portion is arranged such that the pen holder can be retained in position by the engagements between the notch and the pivot axle and between the grooves and the legs of the U-shaped portion.
