Claims

[Scope of utility model registration request]

A horizontal scale 4 is attached to the bottom of the case 2, a long hole 22 is formed along the longitudinal direction in the side wall 2a of the case 2 on the side where the horizontal scale 4 is attached, and the pen support arm 20 is externally inserted through the long hole 22. A support that protrudes and restricts movement of the pen support arm 20 in the X direction along the elongated hole 22, the Y direction along the longitudinal direction of the support arm 20, and the Z direction perpendicular to the bottom wall of the case 2. In an automatic drawing device in which an arm drive mechanism is disposed inside the case 2, a pair of upper and lower brushes 112 and 114 are installed on the side wall 2a at a position that blocks the elongated hole 22.
The pen support arm 20 is inserted between the open ends of the pair of upper and lower brushes 112.114, and the pen support arm 20 is inserted between the open ends of the upper and lower brushes 112. ' A dustproof device characterized in that a mechanism is provided to reduce resistance from the pen support arm 20 applied to the fixed end of the pen support arm 114.
