PURPOSE:To make it possible to find abnormality of injection process in an early stage, by storing data on several molding cycles that has been done, and displaying the data by displaying means. CONSTITUTION:A control means (B) detects various variates by a variate detecting means (A) to write into a current value memory means (C), and when one molding cycle is completed, an update control means (D) writes various variates stored in the current value memory means (C) into a past variate value memory means (E) so that various variate values of several molding cycles before the current molding cycle may be stored in the past variate value memory means (E). Then, when a display command is issued, a display control means (F) reads out values of variates from the current memory means (C) and the past variate value memory means (E) and displays on a display (G) the various variates of the several molding cycles before the current molding cycle. Therefore, since the various variates of the several past molding cycles before the current molding cycle are stored and displayed, one can observe the display to find peculiarity or abnormality of the injection molding process quickly.
