Abstract: A liquid discharging apparatus includes: a head having a nozzle which discharges liquid therefrom; a storing part, at least a part of the storing part being positioned above an opening of the nozzle, the liquid being stored in the storing part while forming a liquid surface; and an atmosphere communicating channel which communicates a gas layer of the storing part with outside of the storing part; and a valve unit which is switched between a communication state in which the valve unit communicates the gas layer of the storing part with the outside and a non-communication state in which the valve unit does not communicate the gas layer of the storing part with the outside. The valve unit is switched from the non-communication state to the communication state in a case that a power source is changed from a turned-on state to a turned-off state.

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.

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.

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.
