ABSTRACT:
A holder member for resting on a user's thigh comprises a plate-like thigh part bent at an obtuse angle for resting on a user's thigh and a plate-like support part extending from an edge of the thigh part at right angles therewith. A desk member for use by the user as a desk comprises a plate-like planar rest part and a plate-like mounting part extending from an edge of the rest part at right angles therewith. A fastening device adjustably movably affixes the desk member to the holder member for rotation of the mounting part of the desk member coplanar with the support part of the holder member about an axis perpendicular to the mounting part and support part and for movement of the rest part of the desk member relative to the thigh part of the holder member to vary the distance therebetween.
