  • Publication number: 20240109332
    Abstract: A recording apparatus includes a conveyance unit that conveys a recording medium in a first direction toward a recording head for ejecting a liquid, a tank including a containing chamber containing the liquid to be supplied to the recording head, and an injection port through which the liquid is injected into the containing chamber, the tank being disposed downstream of the conveyance unit in the first direction, a rotatable lever that holds a tank cap for closing the injection port, and a cover that rotates about a rotation shaft between an open position for exposing the lever and a closed position for covering the lever, the rotation shaft being disposed upstream of the conveyance unit in the first direction. The cover includes a sliding portion that is provided on a surface facing the lever and comes into contact with the lever while the cover is rotating toward the closed position.

  • Patent number: 11674515
    Abstract: A scroll compressor includes a casing, a scroll compression mechanism, a motor, a crankshaft, a bearing, a frame fixed to the casing; and an oil separation member fixed to the frame. The motor includes a stator and a rotor rotatable in a rotational direction. The bearing rotatably supports the crankshaft. The oil separation member suppresses mixing of a refrigerant and a lubricating oil. The frame supports the bearing and has first and second fixed legs fixed to the casing. The oil separation member has a first horizontal and inclined surfaces. The first inclined surface has a first inclined surface upstream portion and a first inclined surface downstream portion. The first inclined surface downstream portion is disposed higher than the first inclined surface upstream portion. The first horizontal surface, the first inclined surface, and the first fixed leg are disposed in order from upstream to downstream in the rotational direction.
