Patent number: 8393722Abstract: A set of cartridges includes a first cartridge including a first tank, wherein a liquid level in the first tank is at a first position when an amount of liquid stored in the first tank is a predetermined amount, and a second cartridge including a second tank, wherein a liquid level in the second tank is at a second position which is below the first position when an amount of liquid stored in the second tank is the predetermined amount. The first cartridge is configured such that a light-blocking portion moves out of a detection region when the liquid level in the first tank lowers and reaches the first position, and the second cartridge is configured such that a light-blocking portion moves out of the detection region when the liquid level in the second tank lowers and reaches the second position.Type: GrantFiled: March 21, 2011Date of Patent: March 12, 2013Assignee: Brother Kogyo Kabushiki KaishaInventor: Hisaki Sakurai
