PURPOSE:To display accurately the channel selection state and to simplify the constitution of a display device by providing the display holes to a display panel at the positions opposite to the channel selection members together with a light source and the display panel and a light guide line to which the introduction of the light sent from the light source is controlled by the forward/ backward movements of the channel selection members respectively. CONSTITUTION:The end part of a shaft lever 6 moves into a counter surface between a light guide line 25 and a light distribution line 27 in a non-channel selection state where a channel selection member is pressed to a rear plate 12'' of a device frame by a reset spring 14 as shown by the virtual lines. Thus the light sent from the line 27 is cut of by the channel selection member and does not reach the line 25. While the lever 6 is removed from the counter surface between both lines 25 and 27 in a channel selection state where the channel selection member moves forward together with an operating member 1 and this move-forward state is locked by a lock plate 16 as shown by the solid line. Thus the light is led to the line 25 from the line 27 and an end face 25' of the line 25 emits the light.
