Abstract: A first cover moves between a first closed position and a first open position. The first cover is located at another end of a housing when the first cover is located at the first closed position. A second cover moves between a second closed position and a second open position. The second cover is located closer to one end than the first cover is at the first closed position and at the second closed position. A first portion of a first conveyance path is formed between the first cover and the second cover at the first closed position and at the second closed position. A second portion of a second conveyance path is formed at a side of the second cover facing the one end at the second closed position. When the first cover opens the first portion, the second cover is located at the second closed position.

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.
