Abstract
A tape recorder apparatus comprising a tape drive circuit, an audio circuit, a record-reproduction changeover switch, a fast forward-rewind changeover switch, and a scan converter. The scan converter receives a forward-run signal or a backward-run signal when the record-reproduction change-over switch or the fast forward-rewind changeover switch is operated. Upon receipt of such a signal the scan converter generates a forward scan signal or a backward scan signal. The tape recorder apparatus is further provided with a display device which displays in response to a scan signal from the scan converter a numeral, e.g. 0, shifted sequentially from the lowest digit position to the highest digit position or vice versa. The direction in which 0 is shiftingly displayed is the very direction in which the tape is running.
