    • PROBLEM TO BE SOLVED: To provide a method of manufacturing an electronic device capable of suppressing deformation of a circuit board and a decrease in packaging reliability of electronic components and capable of improving design properties at low costs, and to provide an electronic device. SOLUTION: The circuit board, where the electronic components are packaged only on the front, is held in a mold cavity such that the back is adhered to an inner surface, and a decorative sheet, where a decorative layer is disposed on one surface of a transparent base material made of a thermoplastic resin, is interposed between the front of the circuit board and an inner surface of the mold that opposes the front such that the decorative layer is located at the side of the circuit board. Then, in this holding state, the thermoplastic resin is filled into the cavity and hardened, a casing for sealing the front of the circuit board including the electronic components is formed such that the back of the circuit board forms one portion of an outer surface, and the decorative sheet is integrated with the casing to form one portion of the outer surface, thus obtaining an electronic key.

    • 要解决的问题:提供一种制造能够抑制电路板的变形并且降低电子部件的封装可靠性并且能够以低成本改进设计特性的电子设备的方法,并且提供一种电子设备 。

      解决方案:电子部件仅在前面封装的电路板被保持在模腔中,使得背面粘附到内表面,并且装饰片在其上设置有装饰层 由热塑性树脂制成的透明基材的表面插入在电路板的前部和与前面相对的模具的内表面之间,使得装饰层位于电路板的侧面。 然后,在该保持状态下,将热塑性树脂填充到空腔中并硬化,形成用于密封包括电子部件的电路板的前部的壳体,使得电路板的背面形成外表面的一部分, 并且装饰片与壳体一体形成外表面的一部分,从而获得电子钥匙。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To enable an operator easily and surely decide the state of a synchronous sensor and the incident state of a light beam without using a particular equipment, to enable the operator easily adjust and repair the synchronous sensor and the incident state of the light beam, and to improve workability.
      SOLUTION: A circuit substrate 23 is formed of a translucent member, and printed parts 28 and 29 as display parts are provided on the side opposite to the mounting face of the synchronous sensor 15 on the circuit substrate 23. Thus, the position at which a laser beam passes through the synchronous sensors 15 and the position of the synchronous sensors 15 are easily recognized from the back side of the circuit substrate 23 opposite to the mounting side of the synchronous sensors 15 or the scanning side of the laser beam, and a defect position is simply specified even in such an optical write-in unit having a plurality of synchronous sensors 15 as a color machine.
