PROBLEM TO BE SOLVED: To reduce the housing production cost, the time and labor required for the management of parts and a storage space of parts respectively by adding the fall and rise active bit codes which engage with each other only between a pair of electronic equipment units and a unit base and permits the connection of them. SOLUTION: The guide projecting parts 101 and 102 are formed in a single body at both sides of a housing to guide the sliding direction when the housing is mounted. Then a fall active bit code BC1 is added on a tip face 103 and a scheduled pin setting position is set on a circuit board 215. A rise active bit code BC2 is formed at the scheduled pin setting position. Then the parts 101 and 102 are fit into a guide groove in a free sliding way. Under such conditions, the codes BC1 and BC2 engage with each other to approach to each other and can be connected together only when the accurate coincidence is confirmed between both codes.
