ELECTRONIC CIRCUIT DEVICE

PROBLEM TO BE SOLVED: To increase number of connecting terminals between a unit and a printed circuit board, by disposing many electric connection terminals on upper, lower, right and left walls and rear walls of a box-shape electronic equipment connected to one or a plurality of printed circuit boards. SOLUTION: In the box-shape electronic equipment 1, a structure of a rectangular hexahedron is adopted, many electric connection terminals 2 extended in a surface direction and made of conductive materials are disposed on five walls 3 of six walls. The residual one wall 4 becomes a protective plate against the equipment 1, the wall 4 is machined so as to observe a lever 5 for handling the equipment 1 and a light emitting element 6 for externally displaying an inner state. Thus, the two or more equipments are adjacently disposed, the terminals are brought into contact with each other, and hence the equipments can be electrically connected.
