Abstract
Abstract Camera image data transfer device 1 of the present invention allows for the assembly of its components, with one component on top of another from the bottom up in one direction: liquid crystal display device for data transfer 6 is mounted in recess 28 on the inner side of first base 2; then, circuit board 5 and second base 3 are placed on top of it in this order; next, liquid crystal monitor display device 7 is mounted on the outer side of the second base; and finally fixture 8 securely fixes the display device to the second base. The whole device is fixed by securing the ends of dowels 21-27 to second base 3 with going through the entire structure and being extended from first base 2. Thus, the structure of the present invention facilitates assembly and produces fewer defects. Since liquid crystal monitor display device 7 can be mounted from the outside of second base 3, the light blocking base 302 can be formed in one body with second base 3, which eliminates the need for a special component for blocking external light which is required by the conventional structure.
