  • Publication number: 20240131848
    Abstract: A liquid ejecting apparatus includes a liquid ejection head to eject liquid, a recovery unit, a housing, a discharge unit, a casing including the discharge unit and the housing, and a liquid receptacle. The recovery unit maintains liquid ejecting performance of the liquid ejection head. The housing houses a container that accommodates liquid received by the recovery unit. The discharge unit discharges the liquid received by the recovery unit to the container. The liquid receptacle is disposed below the discharge unit in a direction of gravity in the casing and includes a first groove extending in a first direction crossing the direction of gravity and a second groove extending in a second direction crossing the direction of gravity and the first direction.

  • Publication number: 20240109330
    Abstract: A printing apparatus includes a liquid tank unit, a printing head, and a supply tube unit. The liquid tank unit includes first and second liquid tanks that store liquid and are arranged in parallel to each other. The printing head ejects liquid from the first and second tanks while moving in a main scanning direction. The supply tube unit includes a first supply tube connecting the first liquid tank to the printing head and includes a second supply tube coupled in parallel to the first supply tube and connecting the second liquid tank to the printing head. The second supply tube transitions from a connected tube state in which the second and first supply tubes are coupled in parallel to a single tube state by being separated from the first supply tube, passes across the first supply tube, and is connected to a connection port of the second liquid tank.

  • 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: 5844801
    Abstract: After outer panels have been assembled on a vehicle frame, they are coated with an aqueous lustering agent P, and then irradiated with a light beam L. Light reflected by the outer panels is processed to produce a degree and range of distortion thereof. Based on the produced degree and range of distortion, it is determined whether the outer panels suffer a surface distortion or not. The determined result is displayed on a display monitor. According to the displayed image, the outer panels are repaired and thereafter coated with a paint.
