  • Publication number: 20220097395
    Abstract: A liquid supplying apparatus having a tank with a hole, a reservoir chamber to store a portion of liquid in the tank, and a flow path to store another portion of the liquid in the tank, is provided. The flow path connects the reservoir chamber and the hole. The flow path has a first funnel section to reduce a cross-sectional area of a part of the flow path. The first funnel section is located at a position equal to or higher than a surface of a predetermined maximum amount of the liquid storable in the tank in a usable posture. The first funnel section creates a meniscus with the liquid stored in the tank in an X1-rotated posture, in which the tank is rotated about a first axis by a first angle from the usable posture.

  • Publication number: 20220097406
    Abstract: A liquid discharging apparatus, having a head, reservoir section, a liquid flow path, a lid, a valve, a switching assembly, and a controller, is provided. The reservoir section has a liquid reservoir chamber, an injection port, and an atmosphere communication path. The liquid flow path connects the head and the liquid reservoir chamber. The lid opens and closes the injection port. The switching assembly switches states of the valve between an opening state, in which the valve opens the atmosphere communication path, and a closing state, in which the valve closes the atmosphere communication path. The controller is configured to control the valve through the switching assembly to close the atmosphere communication path, control the head to discharge the liquid after closing the atmosphere communication path, and control the valve through the switching assembly to open the atmosphere communication path before the liquid is injected through the injection port.

  • Publication number: 20220097386
    Abstract: A liquid discharging apparatus, having a head, a reservoir section including a liquid reservoir chamber and an atmosphere communication path, a liquid flow path, a switching assembly, and a controller to control the switching assembly in a disconnecting process and the head in a discharging process after the disconnecting process, is provided. A volume of an air portion in the reservoir section is controlled to satisfy formulas: Vb=(Po+?P)*?V/?P and ?P?Pm. Po represents one atmosphere. AV represents a change in the volume of the air portion due to a change in a volume of the liquid caused by discharging a predetermined amount of liquid in the discharging process. AP represents a change in pressure of the air portion according to the change in the volume of the liquid in the discharging process. Pm represents a pressure resistance of menisci formed with the liquid in the nozzles.

  • Publication number: 20220097407
    Abstract: A liquid discharging apparatus, having a head, a reservoir section, a valve, a switching assembly, and a controller, is provided. The reservoir section has a liquid reservoir chamber, an air chamber, an injection port, and an atmosphere communication path. The switching assembly switches states of the valve between an opening state, in which the valve opens the atmosphere communication path, and a closing state, in which the valve closes the atmosphere communication path. The controller is configured to control the valve through the switching assembly to close the atmosphere communication path, control the head to discharge the liquid after closing the atmosphere communication path, and control the valve through the switching assembly to close the atmosphere communication path before the liquid is injected through the injection port.

  • Publication number: 20220097401
    Abstract: A liquid supplying apparatus, having a reservoir section including a reservoir chamber, and a communication section connecting the reservoir chamber and a hole, is provided. The communication section has a first wall and a second wall, a first buffer space, and a second buffer space. The first buffer space and the second buffer space store the liquid flowing on the first wall and the second wall, respectively, in the liquid supplying apparatus being in the first rotated posture. The hole is located at an upper position with respect to a surface of a predetermined maximum amount of the liquid storable in the reservoir chamber in the liquid supplying apparatus being in a usable posture. The hole is open neither to the first buffer space nor the second buffer space. The hole is located in neither the first wall nor the second wall.
