    • PROBLEM TO BE SOLVED: To provide a key sheet capable of firmly fixing members such as key tops to a base sheet.
      SOLUTION: Rear surfaces of key tops 4 are firmly fixed to a film sheet 9 without any gaps by an adhesive layer 11 laminated on all the surfaces of the key tops 4. With this, it gets hard for a claw to enter between the key tops 4 and the film sheet 9, and the key tops 4 can be prevented from being peeled off from the film sheet 9. Moreover, since the key sheet 8 integrates such a film sheet 9 with a base sheet 10, the key tops 4 can be firmly fixed to the base sheet 10 though the film sheet 9 to prevent the key tops 4 from falling off by the claw or the like at the time of press operation.

    • 要解决的问题:提供一种能够将诸如键顶的构件牢固地固定到基片上的按键板。 解决方案:键顶4的后表面通过层压在键顶4的所有表面上的粘合剂层11牢固地固定到膜片9而没有任何间隙。由此,爪难以进入 键顶4和薄膜片9以及键顶4可以防止从薄膜片9剥离。另外,由于按键板8将这种薄膜片9与基片10整合,所以键顶 4可以通过膜片9牢固地固定到基片10上,以防止按键操作时键爪4由爪等脱落。 版权所有(C)2008,JPO&INPIT
