DETERMINATION DEVICE, MULTI-AXIS PHOTOELECTRIC SENSOR, METHOD OF CONTROLLING DETERMINATION DEVICE, INFORMATION PROCESSING PROGRAM, AND RECORDING MEDIUM

摘要

To allow for determining causes of output anomalies of photosensitive elements in a multi-axis photoelectric sensor.SOLUTION: A multi-axis photoelectric sensor (1) determines the presence of electric noise when output anomalies are observed in two adjacent light receivable periods (Ts) in one photoreception cycle (Tc).SELECTED DRAWING: Figure 1
