| 摘要 | PURPOSE:To prolong the life of a conductor for using a hinge as a path, by allowing a flexible conductor to pass through continuous hollow joints so that two case parts can be rotated. CONSTITUTION:A calculator 1 is provided with a folding case containing two case half parts 2, 3. On the respective half parts 2, 3, a key pad 4 and 5 are placed, respectively. The pad 4 and 5 are connected electrically to a processor for showing the information on a display 6. These case half parts 2, 3 are connected with a hollow joint so that they can make roughly one rotation each other. In the inside of this hollow joint 7, the U-shaped part 19 of an elastic thin film for connecting elastic thin film keyboard aggregates 16 in the half parts 2, 3 is placed. In such way, in the part for connecting two pieces of half parts 2, 3, remarkable compression and tensile stress caused by usual bending do not exist, therefore, the life of a conductor for using a hinge as a path can be prolonged. | ||||||
