| 摘要 | PURPOSE: To prolong the life of a flexible sheet by putting it in contact with a bent portion in the closed condition, equipping this portion with a guide member having an are-shaped part which gives a mild curve, and thereby securing a desired curve. CONSTITUTION: A pair of keyboards 3, 4 are supported in a single piece with possibility of opening and closing, and a flexible sheet 6 whereon conductor patterns are formed, provides electrical connections, and the bent portion of this flexible sheet 6 in closed condition is contacted, and a guide member 7 is equipped having an are-shaped part 7a which gives a mild curve. By this device the bent portion of flexible sheet 6 can be given a desired curve easily, and desired mild curve in closed condition will not be collapsed even though opening and closing are repeated. Thus the life of flexible sheet 6 can be prolonged. COPYRIGHT: (C)1989,JPO&Japio |
