A guide having a unique folding construction which enables the guide to have all of its components oriented in a straight line condition or enabling the end components to be oriented in perpendicular relation through a novel hinge structure at the juncture between the two end components. The hinge structure includes a triangular rigid component that is connected to the end components by a hinge structure having angularly disposed hinge axes between a triangular connecting member and two end components so that the end components can be oriented in perpendicular relation, in overlying relation or in longitudinal alignment. The foldable guide device may be used for various purposes and is preferably constructed of transparent material and provided with various indicia, guide lines and the like which enable it to be used for various purposes including assistance in accounting entries in a ledger or the like.
