Patterned cover member and electronic device including same

An electronic device is provided. The electronic device includes: a printed circuit board; a light emitting unit and a light receiving unit disposed on the printed circuit board; a cover member having at least a partial region configured from a material having high light transmittance, the cover member being disposed to face the printed circuit board, and including a first region substantially facing the light emitting unit and a second region substantially facing the light receiving unit; and a pattern disposed in at least one of the first region and the second region of the cover member. The pattern may be arranged by repeatedly arranging blocking units having a low transmittance at predetermined intervals. In addition, various embodiments are also possible. 提供了一种电子装置。该电子装置包括：印刷电路板；发光单元和光接收单元，设置在印刷电路板上；盖构件，具有由具有高透光率的材料配置的至少部分区域，该盖构件被设置为面对印刷电路板，并包括实质上面对发光单元的第一区和实质上面对光接收单元的第二区；以及图案，设置在盖构件的第一区和第二区中的至少一个中。图案可以通过以预定间隔重复地布置具有低透射率的阻挡单元来布置。另外，各种实施例也是可能的。
