A cartridge unit for a printer including a cartridge and a circuit assembly. The circuit assembly includes a base member and a circuit substrate having a memory module and a plurality of second electrical contacts. In a cartridge attached state, the circuit assembly is configured to be in a circuit assembly attached state where the circuit assembly is arranged between the plurality of first electrical contacts of the printer and the particular cartridge side wall, the plurality of first electrical contacts electrically contacting the plurality of second electrical contacts, respectively. In a circuit assembly unattached state, the circuit assembly is not arranged between the plurality of first electrical contacts and the particular cartridge side wall. A thickness of the circuit assembly is larger than a distance between the plurality of first electrical contacts and the particular cartridge side wall in the cartridge attached and the circuit assembly unattached state.

A tape cartridge includes a casing, a tape roll, and a ribbon roll. The casing has a tape outlet. The tape roll is formed by winding a fabric tape. The ribbon roll is formed by winding an ink ribbon. The tape outlet is formed at a most downstream end of a tape conveying path of the fabric tape paid out from the tape roll. The fabric tape is discharged through the tape outlet outside. The fabric tape includes a heat cutter processed parts, and a printing part. The heat cutter processed parts are positioned at each end portion in a widthwise direction of the fabric tape. The printing part is positioned between the heat cutter processed parts. The fabric tape is in contact with an outer circumferential part of the ribbon roll on a way of conveying the fabric tape along the tape conveying path to the tape outlet.
