Claims

[Scope of utility model registration request]

A casing 2 that is movably placed on a mounting surface and has an elongated opening formed in its front wall, and an X built into the casing 2 so as to be parallel to the longitudinal direction of the opening of the casing 2. shaft guides 6, 8;
X cursors 10, 12 movably attached to the X-axis guides 6, 8;
2, Y-axis guides 18, 20 fixed in a direction perpendicular to the X-axis guides 6, 8, a Y-cursor 22 movably attached to the Y-axis guides 18, 20, and the Y-cursor. an opening 2 connected to 22 and having a tip provided in the front wall of the casing 2;
a support arm 26 projecting forward from the casing 2 from 9; a pen holder 89 for holding a writing instrument provided at the tip of the support arm 26;
In the automatic drawing device equipped with a support arm drive mechanism that drives the XY cursor along the XY axis guide direction, elastic shielding sheet-like members are provided at upper and lower positions of the opening so as to shield the opening. 103 and 104 are stretched, and the support arm 26 is slidably inserted between the opposing parts of the upper and lower sheet-like members 103 and 104, and between the sheet-like members 103 and 104 and the support arm 26. A dustproof device characterized by interposing a friction reducing layer made of a layer of a material with a small coefficient of friction.
