  • Patent number: 10744758
    Abstract: There is provided a liquid discharge apparatus including: a liquid discharge head having a nozzle surface; a carriage; a carriage mover; a conveyor conveying a medium in a conveyance direction; a velocity sensor; a distance sensor; and a controller. The controller makes a determination regarding the velocity of the carriage based on output of the velocity sensor, and makes a determination regarding the distance between the medium and the nozzle surface based on output of the distance sensor. In a case that that the controller determines that the velocity is less than a predetermined velocity and that the distance is less than a predetermined distance, the controller interrupts recording performed by the liquid discharge head.

  • Patent number: 10682851
    Abstract: A controller is configured to receive an output signal outputted from a light reception element. The controller is configured to perform: an existence detection of controlling a light emission element to emit light and detecting whether an ejection target exists at a facing position based on the output signal; and a distance detection of controlling the light emission element to emit light toward a surface of the ejection target and detecting a distance between the surface of the ejection target and a nozzle surface based on the output signal outputted from the light reception element upon receiving light reflected off the surface of the ejection target. An amount of change of the output signal with respect to change of the distance in the distance detection is larger than an amount of change of the output signal with respect to change of the distance in the existence detection.
