[Prior Art] Conventionally, a cam lever for operating a tilt angle of a drawing board frame of a drafting table is provided on one side portion of an elevating support column to which the drawing board frame is pivotally mounted. When the cam lever is rotated, the cam portion of the lever base presses the brake piece, and the adjusting stay of the drawing board frame held by the braking piece is pressed to fix the drawing board frame at a desired angle. Since the grip portion of the cam lever is pivotally attached to the elevating column so that the grip portion makes a constant angle with the operator, the operator facing the drawing board may reach it depending on the inclination angle of the drawing board. It may be difficult, and there is a problem in operability.

Therefore, it is possible to change the vertical angle of the cam lever, or an engaging member is interposed between the adjusting stay and the cam portion to change the angle of the adjusting stay due to the rotation of the drawing board frame. It is known that the operability is improved by interlocking the angle of the cam lever to reduce the relative angle change between the drawing board frame and the cam lever.

[Operation] The adjustment stay pivotally mounted at a position separated from the rotation axis of the drawing plate frame is engaged with and sandwiched by the bull rake plate provided on the support frame. Then, when the cam lever is rotated to release the brake, the drawing frame can be rotated, and by this rotation, the adjusting stay slides while being held by the engaged brake plate, and the inclination angle is changed. Change. At this time, the brake plate also rotates in conjunction. At the same time, a cam lever whose rotation around the brake shaft is restricted by a guide piece provided on the brake plate is also rotated by the guide piece, so that the operation cam lever is interlocked with the rotation of the drawing board frame. Therefore, the relative angle change between the drawing board frame and the cam lever due to the inclination angle of the drawing board frame is extremely small.

[Advantages of the Invention] As described in detail in the above-described one embodiment, in this invention, the relative angle between the drawing board frame and the operation cam lever is substantially constant regardless of the inclination angle of the drawing board frame. Therefore, even when a large drawing board is placed and the cam lever is hidden on the back surface of the drawing board, the operator can easily operate by extending the arm without visually checking. Further, since the positional relationship between the hand supporting the drawing frame and the hand holding the cam lever is substantially constant regardless of the inclination angle when adjusting the inclination angle, the work posture is not unreasonable and the operability is good.
