The invention relates to the improved structure for an ink cup, particularly such structure having upper and lower cover bodies, a thread winding wheel, a manual turning wheel and an inverted T-shaped pressing disk. The interior of the inverted T pressing disk encloses a compression spring and is set inside the manual turning wheel by means of a hollow circular rod. The manual turning wheel cooperates with a circular hole in the upper cover body, and is urged into contact with the upper cover body by the compression spring in the pressing disk. A spiral spring in the thread winding wheel automatically rewinds the thread except when the manual turning wheel is squeezed against the cover body to stop the thread winding wheel.
