A tape cassette that includes a housing having a front wall and a tape feed exit located on the front wall, a tape included at least partially within the housing, and a pressing portion and a first non-pressing portion on the front wall. The pressing portion and the first non-pressing portion are positioned to oppose tape type detecting switches of the label printer when the cassette is in the label printer. The pressing portion is configured to change a state of an opposing one of the tape type detecting switches, and the first non-pressing portion is configured to avoid changing a state of an opposing one of the tape type detecting switches. The first non-pressing portion is a planar area of the front wall extending in a tape width direction from a top surface of the housing to a bottom surface of the housing.

Provided is a medicine packaging device. The medicine packaging device includes: a reader-writer that reads information from an IC tag installed at a supply core of an ink ribbon roll detachably installed to an ink ribbon cassette as well as writes information to the IC tag; a motor control unit that controls a winding motor for rotating a winding core, based on a used length of the ink ribbon which is information read from the IC tag, so that the ink ribbon of the ink ribbon roll runs in a winding direction at a higher speed than a feeding speed of a continuous sheet for packaging; and a written information output unit that outputs information showing the used length of the ink ribbon which has been changed due to use of the ink ribbon, to the reader/writer as information written on the IC tag.

There is provided a tape cartridge, in which the cartridge case is provided with an outer protrusion portion received by an outer recess portion, the outer protrusion portion blocks insertion of a third core projection into a core hole of a tape core B around which a tape B, which is different in type from the tape A, is wound and which has a shape different from that of the tape core A, by contact with the tape core B when the tape roll A is mistakenly replaced with a tape roll B included in a tape cartridge B, which is configured to be mounted on a tape printing apparatus, and including the tape B and the tape core B.

A tape cassette used for a printer includes a thermal head and a cassette holder to which the tape cassette is attachable. The tape cassette includes a tape roll, a casing, a regulation guide and a pressure member. The tape roll is formed by winding a tape. The tape has a width defining a widthwise direction. The casing accommodates therein the tape roll. A tape conveying passage is defined in the casing. The regulation guide is positioned at the tape conveying passage to restrict displacement of the tape in the widthwise direction. The pressure member is positioned upstream of the regulation guide in a conveying direction of the tape and along the tape conveying passage. The pressure member is in contact with the tape in a contacting direction to apply pressing force to the tape in the contacting direction.

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.
