PROBLEM TO BE SOLVED: To realize signal processing stable in terms of the potential and reduce noises, etc., by securing an earth area in a limited mounting area. SOLUTION: An outer connection connector 6, a poer supply connector 5, a large-scale integrated circuit element 9, a first storage element 3 for storing a preset program, a second storage element for controlling the execution of program, a central computing element 2, and an inner connection connector 7 are mounted on a mounting board 1 along its lengthwise direction. A first electronic part 10 and a second electronic part 11 are mounted, and the second storage element is built in the element 9, further the width of earth pattern between the connector 5 and the first electronic part 10 is set to be large. |
