Abstract: A cassette tape recorder comprising a cassette eject mechanism designed so that a cassette receptacle is positively pivotally moved, by depressing an eject key, to an inclined position where a cassette can be inserted thereinto or removed therefrom, and a safety mechanism for preventing the eject key from being depressed when a playback key is depressed and for preventing the playback key from being depressed when said receptacle assumes the inclined position. The aforementioned cassette eject mechanism also includes cassette push-out means which is so designed as to be actuated by the depression of the eject key at the time when said cassette receptacle has substantially reached said position, thereby pushing said cassette partially out of said receptacle.
