Abstract
Abstract An endless tape recording and reproducing apparatus is provided having a pair of remote dictating units and a pair of remote transcribe units adapted to actuate an integrated dual endless tape unit. Each endless tape has a separate bin along with its own dictate and transcribe controls but each is driven by the same motors driving forward and reverse shafts for each side, and each dictate station and each transcribe station can operate either of the endless tapes. The apparatus utilizes a combination erase magnet adapted to operate a reed switch to provide two functions for the erase magnet and utilizes photo cells to indicate conditions of the endless tape. A new system for adjusting solenoid actuated pinch rollers is also provided along with a new layout path for each endless tape.
