PROBLEM TO BE SOLVED: To search for an analogue waveform wanted to be referred to from the extensive quantity of past analogue waveforms collected in a molding machine for a short time. SOLUTION: A waveform result value holding part 13 temporarily preserves the detection signals from a plurality of sensors as analogue waveform data at every one shot. A logging and history data holding part 14 temporarily preserves result values for monitoring based on the detection signal from a plurality of the sensors as logging data at every one shot and further temporarily preserves the content at the time of generation of abnormality as abnormality history data. Further, a setting device 15 for inputting characteristic quantity and a searching part 16 for performing the searching based on the characteristic quantity with respect to the respective data preserved in the logging and history data holding part to take out the analogue waveform data preserved in the waveform result value holding part corresponding to the data obtained by searching in relation to shot number data or time data are provided and the analogue waveform taken out by the searching part is displayed on a display 17.
