ABSTRACT:
An end predictor is provided for use with a tape cassette of the type which contains a measured length of tape corresponding to a given number of turns on one of the tape hubs mounted therein when the tape is entirely wound on one of the hubs, exclusive of its leader portion extending to the other hub. A tape cassette of this type is indicated by an indication aperture formed in the cassette. When such cassettte is mounted in a tape recorder, the end predictor operates to count the number of revolutions of either take-up shaft or rewind shaft on which the respective tape hubs are mounted, thereby providing an alarm when a predetermined count is reached. Thus a prediction is provided of a terminal end of the cassette tape at a given time interval before the terminal end is actually reached. The detection of the indication aperture is effective to reset a counter arrangement which is associated with a record/playback operation of the recorder.
