    • PROBLEM TO BE SOLVED: To obtain a highly-reliable transmission device for physical data on temperature, etc., and the temperature data transmission device for a hot roller as to the sequential transmission of a plurality of pieces of physical data on temperature, etc., detected on a rotation side to a fixed side.
      SOLUTION: The temperature data transmission device for the hot roller which has temperature detecting elements 14 and 15 arranged on the hot roller 12 and sends temperature data detected by the temperature detecting elements 14 and 15 to a fixed-side reception part 26 by a rotation-side transmission part 25 rotating together with the hot roller 12. The rotation-side transmission part 25 and fixed-side reception part 26 are provided with a rotary transformer 200 and the rotation-side transmission part 25 is provided with a clock generating circuit 41 which generates a clock signal for switching from the waveform of the secondary-side AC power source of the rotary transformer 20.
