Abstract: The present invention provides a main body with a coupling section, wherein the circuit board includes terminals for power supply and for signal, wherein the coupling section has a first positioning section and a second positioning section, and wherein the assembly is configured so that in a state where positioning has been performed by the first positioning section, positioning by the second positioning section is performed and the coupling section is coupled to another coupling section of another main body. Thus, coupling the coupling section is performed in the state where positioning has been performed, wherein connection of the terminals for power supply and for signal to power supply and signal terminal sections is performed in this state, which may enable the operability for coupling a coupling section to be improved while ensuring a mechanically and electrically correct coupled state.
