Abstract

PURPOSE:To establish convenient display unit, by the light emitting display in response to the tape running speed and direction, in interlocking with the operation button of tape recorder. CONSTITUTION:In response to the revolution of the reel shaft 2 running the tape, the pulse by the magnet 6 on the disc 4 is produced with the reed switch 8, it is counted at the counter 10, and the numeral indicating the running position of tape in response to the count value of pulse is displayed on the display section 16 via the decoder 14 with light emission, and the running speed signal produced in interlocking with the operation button 18 of tape recorder is fed to one input terminal of the AND gates 22, 24 via the frequency divider 12 and the decoder 20. Further, the signal from the operation button 18 enters another input terminal of the AND gates 22, 24 directly through the inverter 26, and the arrow toward right and left is displayed on the display section 16. The arrow flickers in response to the running speed of tape.
