The first head has a first part and a second part. The second part is coupled to the first part in a first direction. The second part has a width in a first direction that is shorter than a width of the first part in a second direction. A third part coupled to the first part has a width shorter than the width of the first part in the second direction and is at a position different from the second part in the second direction. The second head includes fourth, fifth, and sixth parts that are arranged similarly to the first, second, and third parts. Parts of the first, second, third, and fourth heads are positioned, respectfully, in the second part, the third part, the fifth part, and the sixth part. ## Claims ### Claim 1 A liquid discharging
