PURPOSE:To prevent a storage element of which stored contents are not desired to be known by other persons from easy fetching or readout by applying specific working to the mounting system of the memory element. CONSTITUTION:Positionally corresponding conductors on both the ends of a base plate are not connected and scrambled so as to be connected to other conductors not corresponding each other. Therefore, the position of each conductor terminal in the right end part 8 corresponds to each terminal 6 of a storage element 3, but the position of each conductor terminal in the left end part 9 does not correspond to each terminal 6 of the element 3. A conductor patterns 11 in the side of a print base board 2 are connected to through holes 12 arranged in two rows, and if numbers corresponding to the terminal numbers of the storage element are applied to these conductor patterns, the same relation as the conductor terminals in the left end is found. Since the storage element 3 is fixed on the position in a case 1 which can not be observed easily by sealing with resin 13 or a metallic case 14, it is difficult to remove the element 3. |
