    Abstract: An object of the present invention is to quickly correct a temperature sensor for an ejection head by, both efficiently and in a brief time, estimating a detected temperature of the temperature sensor for the ejection head in a case where the temperature of the ejection head of liquid becomes sufficiently close to an environment temperature. The temperature of a print head 1 is detected by a diode sensor 17 and the environment temperature is detected by a thermistor 10. Based on a change in the detected temperature of the diode sensor 17 at the time of filling of ink for the print head 1, the detected temperature of the diode sensor 17 in a case where the temperature of the print head 1 becomes close to the environment temperature is estimated as an estimated detected temperature. Based on a difference between the estimated detected temperature and the environment temperature, a correction value of the detected temperature of the diode sensor 17 is set.

  • Patent number: 10671203
    Abstract: There is provided an apparatus that can prevent invoking of unintended functions in gesture operation. The apparatus displays gesture functions executable by movement of touch position, and when movement of touch position satisfies a first condition, confirms executable gesture functions to display confirmed functions. When the movement of touch position satisfies a second condition after the confirmation, the apparatus cancels the confirmation. When the touch input is released in the confirmed state, the apparatus executes the confirmed functions, and when the touch input is released in the canceled state, control does not execute gesture functions.
