There are provided a processor device (16) for an endoscope (12), which can transmit endoscope-running data required for the analysis of the causes of an error and the like while reducing costs required for the communication of endoscope-running data, and an endoscope data collection server (22).An endoscope data transmission unit (30) transmits first endoscope-running data to an endoscope data collection server (22) through a specific network (20) at a first timing. The endoscope data transmission unit (30) transmits second endoscope-running data, of which the volume is larger than the volume of the first endoscope-running data, to the endoscope data collection server (22) at a second timing including a timing when an error is generated.
