  • Publication number: 20240123737
    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 connecting the head with the liquid reservoir chamber, a switching assembly to switch states of the atmosphere communication path between a connecting state and a disconnecting state, and a controller, is provided. The controller is configured to control the switching assembly to switch the states of the atmosphere communication path from the connecting state to the disconnecting state; after switching the states of the atmosphere communication path, control the head to discharge the liquid; and after switching the states of the atmosphere communication path, and in response to a predetermined connection condition being satisfied, control the switching assembly to switch the states of the atmosphere communication path from the disconnecting state to the connecting state.

  • Publication number: 20240100844
    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: 20240066882
    Abstract: There is provided an inkjet recording device including a head, a support member, a storage portion, a valve, an actuator, and a controller. The head includes a nozzle and is configured to eject ink from the nozzle. The support member supports the head. The storage portion storing therein ink. The storage portion has a part positioned above the nozzle. The storage portion has an air communication opening allowing an interior of the storage portion to be communicated with an outside of the storage portion. The valve is movable between an opening position in which the valve opens the air communication opening and a closing position in which the valve closes the air communication opening. The actuator is configured to move the valve. The controller configured to control, while the head is ejecting ink from the nozzle toward a recording medium, the actuator to maintain the valve at the closing position.
