Recording device capable of accurately detecting temperature of recording head

Abstract

To stop recording operation at a maximum temperature regardless of unevenness in temperature characteristics of voltage drop in the forward direction of a first sensor 603. A driving circuit 602 is for driving a recording head 601. Temperature of the driving circuit 602 is detected by the first sensor 603 by utilizing the temperature characteristics of voltage drop in the forward direction of the first sensor 603. At the time of when a recording device 1 is turned ON, a room temperature and an output voltage of the first sensor 603 are stored in a memory 24. Also, a calculation unit 25 performs calculation to obtain a voltage value that the first sensor 603 will output at a predetermined maximum temperature, based on the room temperature and the output voltage stored in the memory 24. When an output from the first sensor 603 reaches the output value calculated by the calculation unit 25, then the control circuit 22 stops recording operation.
