PURPOSE: To eliminate misoperations caused by erroneous setting by providing a distinguishing means which compares input data put in by an input means with set values stored in a memory means and makes the memory means store data, if data is satisfactory to molding terms, and also by providing a distinguishing means to put out an alarm, if not satisfactory.
CONSTITUTION: An input means A to put in set values of each item of molding terms and a memory means C to store set values of each item of molding terms are provided. When set values of each item of molding terms are put in by the input means A, set values of each item of molding terms concerned with the items put in are read out of the memory means C and compared with by a distinguishing means B. Provided data put in and compared with the set values of molding terms is satisfactory to the molding terms, data is put in and set in the memory means C as set values of set items. On the other hand, if data put in is not satisfactory to the molding terms, an alarm is put out of a display means D and data put in is not set as set values.
