ABSTRACT:
The present invention is a magnetic tape running state and tape run amount display device which displays visually the running direction and speed or the run amount and direction of the magnetic tape. An up-down counter is provided with a clock input signal having a pulse generated in correspondence with the run of the tape and is also provided with a count control signal. The count control signal has an UP signal generated when the tape is being transported in a first or forward direction, and has a DOWN signal generated when the tape is being transported in a second or reverse direction. The up-down counter provides a binary output count signal to a display circuit in correspondence with the clock input signal and the count control signal. The up-down counter can also be provided with a reset input responsive to a reset signal which acts to reset the count back to logic 0. The display circuit provides a visual representation of the binary output signal, and may include a first binary-to-digital decoder and a second binary-to-digital decoder, each being responsive to a preselected portion of the binary bits provided by the up-down counter. A plurality of light emitting diodes are connected between decimal output lines of the first and second binary-to-digital decoders for providing a visual indication of the tape running state and run amount. In one arrangement, the diodes are arranged to define a line. The display circuit also can be responsive to the binary tuning signal provided by an electronic tuning type receiver.
