Abstract
A manipulation device has a board and a manipulation panel to cover the board. The board has a printed circuit, a light emitting element mounted on the board for emitting light, a light guide having a incidence part to guide the light incident from the incidence part to a predetermined direction along a surface of the board, and a retention cover to retain the light guide. The retention cover is positioned such that the incidence part of the light guide faces the light emitting element. The retention cover covers a surface of the light guide opposite to the surface of the board. The manipulation panel has a light transmission part formed at a position corresponding to an emission part of the light guide to discharge the light emitted from the light guide to an outside through the light transmission part.
