PROBLEM TO BE SOLVED: To provide a device which extends the function by coupling other unit.SOLUTION: A device has a housing including a first end wall in contact with other unit and a second end wall forming a corner with the first end wall, and a coupling member arranged at a corner and rotating about a first axis parallel with the first end wall. The coupling member includes a semicylindrical link part partially projecting from the first end wall when rotating for coupling, and an operation part exposed to the second end wall and being operated externally. The housing includes a semicylindrical storage slit extending along the first axis so as to store the link part. |
