摘要： An image recording device is provided, having a recording unit configured to record an image on a sheet, and a tray disposed below the recording unit. The tray includes a sheet holding surface configured to hold the sheet. Additionally, the image recording device includes a sheet feeder disposed between the recording unit and the tray. The sheet feeder includes a roller for feeding the sheet from the tray. The roller is configured to move between a first roller position in which the roller contacts the sheet holding surface of the tray and a second roller position in which the roller is separated from the sheet holding surface. A return guide, disposed between the recording unit and the sheet feeder, defines a second conveying path to guide the sheet having an image recorded on one side thereof back to the feed guide. The return guide has a first opening configured to accommodate the roller of the sheet feeder when the roller is in the second roller position.

摘要： A cassette tape includes: a cassette case; a first tape roll and a second tape roll accommodated in the cassette case and rotatably supported thereby; and an RFID tag disposed at one of an upper wall and a lower wall of the cassette case. The first tape roll includes a first tape wound about a first winding axis extending in an axial direction. The second tape roll includes a second tape wound about an axis different from the first winding axis and extending in the axial direction. The second tape roll has a smaller diameter than the first tape roll. The RFID tag includes an antenna and a storage element for radiocommunication to read and write data. A part of the RFID tag is positioned to overlap with a part of the first tape roll in a predetermined direction parallel to the axial direction.

摘要： A cassette is detachably attachable to a printing device in a first direction, the printing device including a print head, a platen roller, a motor for generating a driving force to rotate the platen roller, and a power transmission portion for transmitting the driving force to the platen roller. The cassette includes a printing tape, a casing accommodating the printing tape, and a pressure portion. Upon attachment of the cassette to a cassette receiving portion of the printing device, the pressure portion is configured to move a specific gear of the power transmission portion in the first direction to allow the power transmission portion to mechanically switch a ratio of a rotation number of the platen roller to a rotation number of the motor in accordance with a position of the specific gear in the first direction.

摘要： A printing device includes: a housing; a print head extending in a first direction; a cassette receiving portion; and a movable cover. The cassette receiving portion is open in a second direction orthogonal to the first direction. The cassette receiving portion can selectively receive a first cassette or a second cassette whose size is greater than that of the first cassette. The movable cover is movable between a closed position and an open position for covering and exposing the cassette receiving portion in the second direction. The cassette receiving portion provides: a first cassette receiving portion for receiving the first cassette with the movable cover at the closed position; and a second cassette receiving portion for receiving the second cassette with the movable cover at the open position. A portion of the second cassette receiving portion is overlapped with the movable cover at the closed position in the first direction.

摘要： An image reading device includes a tray unit, a recording unit disposed above the tray unit, an outer guide defining a curved path extending from the tray unit to the recording unit, a sheet feeder configured to feed a sheet from the tray unit to the curved path, and a return guide disposed between the recording unit and the tray unit. The return guide pivots about a shaft and guides the sheet having an image recorded thereon back to the curved path. The tray unit includes at least one supporting portion. The return guide includes at least one supported portion. The at least one supporting portion of the tray unit engages the at least one supported portion of the return guide such that the return guide takes a guiding position in which the return guide defines a return path extending to the curved path.
