PROBLEM TO BE SOLVED: To provide a simple waveform monitoring device which abolishes an appearance test to be performed after molding a molded object and prevents a defective molded object from slipping out of the line by determining it by marks attached to waveforms of actual measurements for distinguishing the defective molded object prior to the molding of the molded object and upgrade the productivity by detecting the faults of a molding machine, equipment and molding conditions during molding. SOLUTION: The simple waveform monitoring device 10 is built in an injection molding machine 20 and monitors the waveform set based on a pressure of a hydraulic cylinder 23 of the machine 20. In addition, the device 10 is equipped with a sensor 12 which generates pressure data of the hydraulic cylinder 23 and a distinguishing device 11 which sets a reference pressure waveform based on the pressure data loaded from the sensor 12 and sets the waveform of actual measurements and displays the waveform of actual measurements with a marker when the pressure data exceeds a specified range to the reference pressure waveform.
