ABSTRACT:
A pushbutton tuner display apparatus for an entertainment device is disclosed in which a plurality of pushbuttons are used to tune a radio apparatus in the entertainment device in one mode of operation, while in another mode of operation the entertainment device operates as a cartridge tape player in which the pushbuttons are utilized as display devices which indicate which tape track is being monitored by the cartridge tape player. Additionally, one pushbutton is utilized as a display to indicate the reception of a stereo radio signal. Each pushbutton comprises a clear plastic light pipe surrounded by an opaque plastic part having openings at the front and rear. An associated light bulb mounted inside the frame of the entertainment device is utilized to provide light to each rear portion of each light pipe, and each light pipe has a prismatic portion which transmits received light to a front portion of the light pipe where an illuminated operative state display indication is produced.
