る。 Reference numerals 2 and 2a denote a pair of hollow support frames, and leg members 4 are protruded from the front portions of these frames. Reference numeral 6 denotes a drawing board placed on the support frames 2, 2a via a spacer, and the front end surface of the drawing board 6 is connected to the support frames 2, 2a.
Mounting plates 8, 8 each fixed to the front end of 2a
a with screws, and the rear end surface of the drawing board 6 is
Plate members 12, 12 fixed to sliding frames 10, 10a slidably fitted to support frames 2, 2a, respectively;
It is fixed to a with a screw. Reference numeral 14 denotes a small article storage container, which is fixed to the mounting plates 8, 8a. A hollow reinforcing frame (not shown) is installed at a suitable location between the supporting frames 2 and 2a. Reference numeral 16 denotes a hollow shaft that fits into a horizontal hole 18 formed at the rear of the support frames 2, 2a and is installed between the support frames 2, 2a. It protrudes outward by a predetermined amount. Reference numerals 20 and 20a denote a pair of triangular plate-shaped cams, and the outer peripheral surfaces of both ends of the hollow shaft 16 fit into holes made through the corners of the cams. It is configured to be rotatable. 22 is a pipe-shaped spacer that fits on the outer peripheral surface of the hollow shaft 16;
A cap 24 is fixed to both sides of the hollow shaft 16. The other end of the hollow shaft 16 also has the structure shown in FIG. The pair of cams 20, 20a
A connecting member 25 made of a hollow shaft is installed between them. Reference numeral 26 indicates a recessed portion for finger operation, and 28 and 30 indicate protrusions, which are provided in a protruding manner on the cams 20 and 20a, respectively.
