44 of the circuit board 40 the other distal portion 32 b of the elastic contact armatures 32 are situated sequentially to the base 31 the two elastic contact armatures 32 are bilateral symmetry the elastic contact armatures 32 of the connecting member 30 are inserted into a hole 24 of the case 20 and project the designated height h2 from the bake surface of the bottom wall 29 before the circuit board 40 is fixed to the case 20 see fig4 the designated height h2 is slightly taller than the designated height h1 and slightly shorter than the designated height h3 when the circuit board 40 is fixed with the elastic locking armature 23 to the liquid crystal display 10 and the connecting member 30 the distal portion 32 a of the elastic contact armatures 32 of the connecting member 30 is pressed and the elastic locking armature 23 is bent at the other distal portion 32 b the circuit board 40 is formed of glass reinforced plastics with copper tracks in the place of wires the connector 41 is mounted on the back of the circuit board 40 so that the other distal portion of a flexible electric wiring member 14 can be connected the flexible print wiring member 14 is inserted into the hole 28 of the case 20 and the distal part is connected to the liquid crystal display 10 and the other distal part is connected to the circuit board through the connector 41 the circuit board 40 includes a round shape hole 42 corresponds to the positioning member 22 and a rectangular shape hole 43 corresponds.
