Abstract
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.
