DOZE DETECTING DEVICE

PROBLEM TO BE SOLVED: To accurately detect a doze without being influenced by a posture, an air temperature and an individual difference by providing an awakening degree judging means to output a signal corresponding to an awakening degree to an external part, a skin temperature detecting means and a detection control means to control an action of the awakening degree judging means. SOLUTION: An air temperature detecting means 15 is composed of an air temperature sensor 3, and detects an air temperature by receiving a trigger signal from a detection control means 11, and outputs it to a temperature data holding means 4 of a data holding means 16. A temperature processing means 5 reads nasal bone upper skin temperature data, masticatory muscle upper skin temperature data and air temperature data from the temperature data holding means 4, and performs, for example, moving average processing for past 300 seconds on the temperature data, and outputs its operation result to an operation result holding means 6. An awakening degree judging means 7 detects a skin temperature change generated according to reduction in an awakening degree from a moving average temperature registered in the operation result holding means 6, and outputs a symptom of a doze and a signal corresponding to the doze to an external part on the basis of the skin temperature change.
