Tape recorder control system for automatically reversing tape

Claim 1

For a tape recorder capable of producing a tape-stop signal indicating that tape feed has stopped, a control system, comprising: a motor for driving reels; a plurality of switches including a recording switch to actuate a recording function for producing recording input signals, a reproducing switch to actuate a reproducing function for producing reproducing input signals, a stop switch to actuate a stopping function for producing stopping input signals, a fast forward switch to actuate a fast forward tape feed function for producing fast forward input signals, and a rewind switch to actuate a rewind function for producing rewind input signals; an LSI circuit having a plurality of input terminals each connected to one of said switches for receiving the respective input signals and having an input terminal for receiving tape-stop signals; said LSI circuit being responsive to the signals at the input terminals for producing recording and reproducing output signals, motor forward and reverse output signals, and tape-stop output signals in response to the tape-stop signals, said LSI circuit having a plurality of output terminals at which respective ones of said output signals appear; recording and reproducing means responsive to the recording and reproducing output signals for recording and reproducing data; power switch means coupled to the output terminals and responsive to said motor forward and reverse output signals for supplying power to the motor in response to the motor forward and reverse output signals; and feedback means outside the LSI circuit and external to the terminals thereof and responsive to the stop-tape output signals and coupled to the input terminal connected to the rewind switch.
