A liquid ejection apparatus includes: a liquid ejection head configured to eject liquid; a liquid storage container including a storage portion configured to store liquid to be supplied to the liquid ejection head, an opening configured to supply liquid from a liquid refill container to the storage portion, and a cover member configured to be in a first state to cover the opening and a second state to expose the opening; and a regulation unit configured to regulate transition from the first state to the second state of the cover member. Regulating by the regulation unit is released when a first portion, of the liquid refill container, configured to prevent misfilling the storage portion with an incorrect liquid, is fitted into a second portion of the liquid ejection apparatus.

Included are a rolled-paper accommodation unit configured to accommodate rolled paper; a thermal head that performs printing on recording paper pulled out from the rolled paper; a control unit configured to control the thermal head; an apparatus case in which the rolled-paper accommodation unit and the control unit are provided, the apparatus case having a first edge forming a discharge opening through which the recording paper on which the thermal head performed printing is discharged; and an opening/closing cover opening or closing the rolled-paper accommodation unit and having a second edge that faces the first edge to form the discharge opening when the opening/closing cover closes the rolled-paper accommodation unit. The rolled-paper accommodation unit is provided between the first edge of the apparatus case and the control unit.

The rolled-paper accommodation unit is provided between the first edge of the apparatus case and the control unit.

A printing apparatus includes a tank configured to contain liquid to be supplied to a print head performing a printing operation by ejecting the liquid, a flow channel configured to supply the liquid from the tank to the print head, a power supply unit configured to receive electric power and supply the electric power to the printing apparatus, and a closing mechanism configured to close the flow channel in response to stoppage of electric power supply to the power supply unit.

A printing apparatus includes a support member having a bearing portion, and includes a locking member including a shaft portion fitted to the bearing portion and a biasing member arranged to bias the support member and the locking member in a first direction. The support member supports a printing member that prints on a printing medium. The locking member is pivotally mounted to the support member. The shaft portion is a pivot center. The locking member fixedly holds the printing member relative to the support member. The first direction forms an angle from 0 degree to smaller than 45 degrees relative to an upper surface of the printing member in a first state in which the printing member is fixedly held relative to the support member by the locking member. Movement of the shaft portion fitted to the bearing portion in the first direction is restricted by the biasing member.

A top cover moves between a first position where the top cover is opened with respect to a lower cover and a second position where the top cover is closed with respect to the lower cover. A label peel-off unit moves between a third position where the label peel-off unit is opened with respect to the lower cover and a fourth position where the label peel-off unit is closed with respect to the lower cover. A lock portion engages with an operable engagement claw provided on the top cover and an engagement claw housed in the lower cover to prevent the top cover from moving from the second position. A protruding portion is a part of an exterior member of the label peel-off unit, protrudes upstream in a label conveying direction, abuts against the engagement claw, and causes the label peel-off unit to move from the fourth position to the third position by the engagement claw.

A method for filling a reservoir of a printing device that includes conducting an unattended refill process of an internal reservoir in response to a detection of a fluid supply unit. In an example, the supply dock fluidically, electrically, and mechanically couples to the fluid supply unit to the printing device.

The printing apparatus of the present invention includes: a print head; and a liquid storage container in which a liquid storage chamber that stores a liquid to be supplied to the print head, an atmosphere communication chamber that communicates with the atmosphere, and a communication flow path that causes the liquid storage chamber and the atmosphere communication chamber to communicate are formed integrally. The liquid storage container can take a first posture in which the atmosphere communication chamber is located under the liquid storage chamber in the direction of gravity and a second posture in which the atmosphere communication chamber and the liquid storage chamber are located side by side in the horizontal direction. In the case where the liquid storage container is in the second posture, the liquid injection portion and the communication flow path are located on the upper side of the liquid storage container.

Provided is a printer, which serves as an information processing device and which includes: a housing; a cover including a first surface, in which an opening is formed, the cover being configured to pivot about an axis of a first rotating shaft parallel to the first surface; and a touch panel, which is to be located in the opening when the cover is in a closed state in which the cover covers the housing. The cover includes a frame between an edge of the first surface and the opening.
