Abstract

PURPOSE:To easily reduce a cost and to easily manage reliability by providing a light guide part which guides light from a light source to the outside of a device. CONSTITUTION:The transparent or translucent light guide part 13 is provided on the opposite side of a liquid crystal display part 3 by interposing the light source 6. In the case the light from the light source 6 enters a light guide plate 5 and irradiates the display part 3. Simultaneously, it is also guided to the outside of the device by the light guide part 13. Thus, since the light from the light source can be confirmed from the opposite side of the liquid crystal display part, it can be confirmed from the outside whether a power source is turned on or off even when a display block is closed. Since a dedicated LED or the like need not be used, the number of parts can be reduced. Besides, the cost of the parts and the cost of assembly can be reduced and the reliability is easily managed.
