ABSTRACT:
A tape recorder in which a counter indicates the tape length traversed in the recorder. The counter may be returned to an initial position by a manually operated element. A switching unit for shutting off the drive for the tape, is coupled to the counter so that the drive for the tape is shut off when the counter has returned to its initial position. The counter, furthermore, may be set to a pre-initial position ahead of the first-mentioned initial position by an amount of tape length which corresponds at least to the length of a dead portion of the tape, on which no recording or playback is possible. The recorder is also provided for resetting the speed of the tape from normal speed for recording or playback, to fast speed in the forward and rewind directions. The shutting off of the drive may be operated so that it becomes ready to function only when the fast forward setting is made. The counter may have numbered dials mounted on a common axis and bearing the indicated numbers on their circumference.
