<p>PROBLEM TO BE SOLVED: To make it possible to surely store data even when the peripheral temperature of a data recorder rises in respect to a mobile object data recorder suitable as a device for recording and storing the operation data on mobile object under a prescribed condition. SOLUTION: An operation data detecting sensor 12 for detecting the operation data of a vehicle is connected to an ECU 10. The ECU 10 repeatedly overwrites the operation data of the vehicle on a memory device 30, and at the time of detecting deceleration exceeding a prescribed value, the recorded contents of the device 30 are stored. The device 30 is stored in a vacuum room 22a formed in a heat resisting case 20 by supporting pins 26 to 26. Power is contactlessly supplied by a light source supplying power source 16 and a photoelectric transducer element 32. Data are contactlessly written by a signal light source 14 and a phototransistor 34.</p> |
