PURPOSE:To display accurately the display state and to simplify the constitution of a display device by providing the display holes on a display panel at positions opposite to the channel selection members together with the display bars which move along the surface of the display panel in response to the forward/backward movements of the channel selection member to open and close those display holes. CONSTITUTION:The display part bars 26 are moved up and down along the slide grooves 27 formed to the shaft levers 6 of channel selection members respectively on the inner surface of a display panel 23. Then the display holes 24 are formed at positions of each groove 27 and opened and closed by the up-down movements of the bars 26. Thus the bars 26 fitted into the grooves 27 are moved up and down with the pressure contact between the end part of the shaft lever 6 and a cam part 25 in a non-channel selection mode where the 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. Then the holes 24 are closed by the moving bars 26. Under such conditions, the color layers of bars 26 are displayed through holes 24. While the bars 26 drop by their empty weight to open the holes 24 in a channel selection mode where the channel selection member moves forward together with an operating member and this move- forward state is locked.
