Abstract
Abstract A writing board for use as an accessory to a brief or attache case has a main housing and four telescopically received auxiliary panels. The auxiliary panels may be telescoped outward to form together with the main housing a large surface on which to rest papers and files or telescoped into the housing in overlapping relationship to form a compact unit readily stored within a brief or attache case. The housing is formed of three parallel plates spaced apart to form two passages in each of which a pair of auxiliary panels is received. Strips of panel material, metal channels or special clips may be used to hold the plates of the housing in proper spaced relation. The two lateral auxiliary panels include pockets to secure papers and the edges of one auxiliary panel and the housing include lips to limit slippage of papers or writing tools into a seated user's lap.
