PURPOSE:To keep a contact invisible from the upper side of a key operation section. CONSTITUTION:A light transmission member 21 made of soft rubber is provided with a plurality of key operation sections 22. A sheet member having contacts 28 is laid on the lower side of the member 21. When the sections 22 are pressed, the contacts 28 come in contact with the conductive patterns 35 of a circuit substrate 29. Also, a visible LED 38 illuminates the key operation sections 22 via a light introduction section 24. As a result, the upper surface of the contacts 28 on the lower side of the sections 22 is covered with the sheet member 27. According to this construction, the contacts 28 are not seen from the upper side of the sections 22 even under illumination. |
