PURPOSE:To prevent breakdown, by flexibly linking blocks at the end parts in a mutually chained state, forming a first protecting film on the assembly of the blocks with thermally shrinking resin,and forming a second protecting film for outer decoration on the outside of the first film. CONSTITUTION:Blocks 3,4, 5, 6 and 7 other than a conducting sheet 8 are all formed in single block units. Each element can be freely incorporated in the block. A block linking rod 9 is inserted in a block linking hole, which is provided at the end part of every block, in which each element is incorporated. Thus linking is performed. After the blocks have been linked, the conducting sheet 8, which is thermally compressed to a circuit board 16 of a circuit block 4, is arranged on the lower surface of each block. A switch part pattern, a motor output pattern and the like are suitably arranged in each block. When the elements are separated into a plurality of blocks in this way, the strengths of the various elements can be reinforced, and breakdown of the device can be prevented. |
