As shown in Japanese Utility Model Application Publication No. 57-27396, the flexible parallel ruler is designed so that a pair of cursors supporting the ruler move in synchronization with each other along rails arranged on both sides of the drawing board. The pair of cursors is
They are connected via transmission shafts placed across both sides of the drawing board. The above-mentioned transmission shaft was arranged outside the drawing board along the vicinity of the upper edge of the drawing board. I couldn't install the lighting equipment because it got in the way. Note that since rails are fixed on both sides of the drawing board, the rails get in the way and make it impossible to attach lighting equipment. Therefore, as shown in FIG.
A groove 4 is formed along the longitudinal direction of the drawing plate 2, a transmission shaft 6 is arranged in the groove 4, and the transmission shaft 6 is housed inside the drawing board 2, thereby illuminating the upper edge of the drawing board 2. The vise-type attachment part of the instrument can be fixed.

However, since the groove 4 is open to the outside over its entire length in the longitudinal direction, outside air constantly enters through this opening, causing the inside of the groove 4 to repeatedly dry and wet. The adhesive that adheres the flat plate 10 to the lower surface of the body 8 and the adhesive that adheres the back sheet material 12 to the flat plate 10 deteriorate, causing the flat plate 10 to deteriorate.
Also, there was a defect that the back sheet material 12 was easily peeled off.

In order to achieve the above object, the present invention surrounds a quadrilateral with a frame 16, and inside the frame 16, a transmission is opened at the lower surface of the frame 16a, which is perpendicular to the frame on the rail attachment side. A shaft insertion groove 30 is formed in the frame 1.
6a over the entire length in the longitudinal direction, and the frame 1
Flat plates 18 and 20 are fixed to the upper and lower surfaces of 6a, the opening along the longitudinal direction of the groove 30 is covered by the flat plates 20, and a reinforcing material 28 is installed between the flat plates 18 and 20.
It is filled with

In the above configuration, the flat plate 20 covers the opening of the transmission shaft arrangement groove 30 formed in the frame 16a constituting the upper edge of the drawing board over the entire length thereof in the longitudinal direction. Therefore, the flow of air into the groove 30 is extremely restricted, and there is almost no change in humidity or humidity within the groove 30.
