คำแปลของ "mechanical pencil" เป็น ไทย

(US) A device, roughly the shape of a pen, into which long thin piece of pencil lead can be placed. A button can then be used to adjust how much of the pencil lead extends beyond the tip of the mechanical pencil, so one can adjust it as the pencil lead wears off through usage. Mechanical pencils usually also have a small eraser at the end opposite the tip. [..]
