A structure of electronic pen calculator is constructed by forming two rectangular windows in upper face of a pen body for accommodating a printed circuit board and exposing a keyboard and a LCD over those two windows, wherein an inverse T-groove with a wide body and a narrow head is formed on back of the rectangular windows; top end of the pen body is sleeve-jointed with a pen cap which is coupled to a clamping rod laterally; a protruded dot is formed on inner face at tail end of the clamping rod, and a stopping rib is disposed on opposite inner face of the pen cap; when the pen cap is sleeve-jointed onto the pen body, the stopping rib is embedded in the inverse T-groove, and the pen cap can slide to the right, left, up, or down within a regulated scope, so that the protruded dot can be positioned above any desired keys and pressed for data input; the calculated answer will be shown on the LCD; a slipping- resist sleeve is jointed to a lower end of the pen body to prevent hand from slipping when writing.
