That is, the handle 5 is attached to the third support 63 to be rotatable about a third rotation axis Z extending through the third supports 63.
  • the first rotation axis X and the third rotation axis Z are parallel to each other.
  • the third supports 63 are provided at an opposite end of the operation housing 2 from the first support 61, that is, at an end provided with the end surface 26 to protrude beyond side surfaces of the operation housing 2 (side surfaces facing each other in a direction along the third rotation axis Z).
  • the handle 5 In a state where the function housing 3 is in the closed position, the handle 5 is rotatable on an opposite side from the battery pack 4. That is, also when the function housing 3 and the operation housing 2 are located to overlap each other in the thickness direction of the function housing 3, the handle 5 is rotatable on a side where the function housing 3 and the operation housing 2 are provided. That is, as illustrated in FIG. 1 , when the handle 5 is rotated to move upward with the function housing 3 being in the closed position, the handle 5 rotates such that the hanging part 52 of the handle 5 passes through a side where the function housing 3 is provided (e.g., above the function housing 3). Then, in a state where the function housing 3 is in the closed position as shown in FIG. 8 , the handle 5 protrudes in the prescribed direction S.
  • the function module 1 can change the state of the handle 5 from a state where the handle 5 protrudes in the prescribed direction S to a state where the handle 5 protrudes on an opposite side from the prescribed direction S and vice versa with the function housing 3 being in the closed position, that is, in a compact form.
  • the function module 1 according to the present embodiment is convenient to use.
  • the first embodiment is one of the various embodiments of the present disclosure. Various modifications may be made to the first embodiment depending on design or the like as long as the object of the present disclosure is achieved.
