Kind Code:
A
Abstract:
To provide a keyboard device capable of suppressing an interference between a light source wiring pattern on a membrane sheet and a matrix wiring pattern of a key switch with a simple configuration and also maintaining wiring strength, and to provide an electronic apparatus.SOLUTION: A keyboard device has a four-layer membrane sheet 31 configured by sequentially laminating a lower sheet 4, a spacer sheet 3, an upper sheet 2, and a light source mounting sheet 1 from bottom to top. On an upper surface of the lower sheet 4, a matrix wiring pattern L4 that connects a fixed contact S4 is formed. On the lower surface of the upper sheet 2, a matrix wiring pattern L2 that connects a movable contact S2 is formed. The spacer sheet 3 forms an air gap part 3a of a through-hole that enables the fixed contact S4 and the movable contact S2 to be in contact with each other. On the upper surface of the light source mounting sheet 1, an LED light source 40 and a light source wiring pattern L40 that connects the LED light source are formed.SELECTED DRAWING: Figure 4
