  • Patent number: 4237373
    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.

  • Patent number: 4225968
    Abstract: The present invention is an electronic tuning type receiver having a band display unit and a numerical frequency display unit. The numerical frequency display unit provides a visual numerical display of the frequency selected by the receiver. The band display unit provides a visual indication of the relationship of the selected frequency with respect to the frequency band being tuned by the receiver.

  • Patent number: 4205353
    Abstract: A combination device having a magnetic recording and reproducing unit and an electronic tuning type receiver, where the channel presetting switches of the electronic tuning type receiver also can act as the operating switches of the magnetic recording and reproducing unit. The electronic tuning type receiver is of the type which is tuned by control signals provided to a tuning means by a plurality of channel selecting switches. A selection circuit is interposed between the tuning means and the plurality of channel selecting switches and provides the plurality of control signals to the tuning means when a selection switch is in a first binary state, and provides the plurality of control signals to a tape-control section when the selection switch is in a second binary state. The tape-control section, in response to the plurality of control signals, controls the mode of operation of the magnetic recording and reproducing unit, and also provides a signal indicating the mode of operation to a sensing circuit.

  • Patent number: 4196395
    Abstract: A preset state indicating unit for use in an electronic tuning type receiver generates a visual indication when both a presetting switch and one of a plurality of channel selecting switches have been properly selected. The preset state indicating unit thus insures that tuning information pertaining to a selected station is actually stored in memory during the presetting operation done by the user.
