1. A recording apparatus for recording on a recording medium by using a recording head, said recording apparatus comprising:

  • a temperature sensor provided within the recording head;

    acquiring means for acquiring information relating to an estimated temperature of an outer wall of the recording head by estimation based on an output of said temperature sensor, the estimated temperature of the outer wall of the recording head being correlated to the output of the temperature sensor;

    control means for suspending a recording operation of said recording apparatus when it is determined that the estimated temperature of the outer wall of the recording head is above a first predetermined temperature, based on the information acquired by said acquiring means, and resuming the recording operation after execution of a predetermined suspension operation; and

    an exchanging mechanism for exchanging the recording head, wherein said control means controls movement of the recording head to a predetermined waiting position where it is difficult for a user to touch the outer wall of the recording head during the predetermined suspension operation, wherein when the estimated temperature of the outer wall of the recording head is above the first predetermined temperature, said control means suspends the recording operation of said recording apparatus until the estimated temperature of the outer wall falls below a second predetermined temperature lower than the first predetermined temperature and resumes the recording operation after the estimated temperature of the outer wall falls below the second predetermined temperature, and wherein said control means inhibits the operation of said exchanging mechanism when the recording operation is suspended.
