    摘要： The present invention purports to provide a tape recording/reproducing apparatus capable of causing a plurality of tapes having different width respectively to travel smoothly and its cassette. The cassette positioning spring 1 gives an appropriate pressing force even in the case that the cassettes have different thicknesses, and the cassettes are respectively fixed at predetermined positions so that the lower edges of the magnetic tape 3a, 3b are positioned at the same height. The flange 9 of the guide post 12 is shifted in an up-and-down direction in response to a magnetic tape width signal detected through the cassette detecting switch 13 or the beginning edge detector 14a, or the ending edge detector 14b, so that even narrow magnetic tape 3a can travel at the predetermined height. Furthermore, by changing the inclined angle and/or the inclined direction of the movable post 10, a downward torsion force is applied to the narrow magnetic tape 3a. In this fashion, magnetic heads to be used are selected in accordance with the magnetic tape width detected by the cassette detecting switch 13 or the beginning edge and the ending edge detectors 14a, 14b.

    摘要： A pneumatic monitoring system for a magnetic tape drive includes a single sensor which includes a differential pressure transducer. Points in the tape drive to which vacuum is applied are coupled to one side of the sensor and points in the tape drive to which pressure is applied are coupled to the other side of the detector. The sensor produces an analog voltage representing the state of the pneumatic system. It is digitized and applied to a microprocessor which compares the sensor voltage to present ranges for calibrated conditions of the tape drive. If the sensed voltage is outside of these ranges, error conditions are indicated.

    摘要： A tape end warning apparatus comprises an alarm switch which is closed in response to the detection of a terminal end of a running tape being reached during a record or playback operation of a tape recorder, and an oscillator circuit which is activated by the closure of the switch. The oscillator circuit produces an alarm signal which is fed to an amplifier inherently contained in a tape recorder so as to give off an audible alarm through a loudspeaker which is connected with the amplifier.
