摘要： In a magnetic tape-automatic tracking method, at least one of the positions of the upper and lower edges of a magnetic tape is detected by an assembly of a tape edge position sensor and light-emitting diode. Any displacement of the running magnetic tape from its standard vertical position is determined from detected data. A generally vertical tape edge position-compensating post which applies a tensile force to the magnetic tape in contact therewith is rotated in a vertical plane by a reversible motor in accordance with the detected extent of the displacement of the running magnetic tape from its standard vertical position. The magnitude of a tensile force applied by the tape edge position-compensating post to the magnetic tape is varied, by the extent of the rotation of the reversible motor. As a result, the magnetic tape is vertically moved in the desired direction to regain its standard vertical position.

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.

摘要： A display apparatus for tape running positions is provided with a first pulse generator (36) for generating m first pulses for each revolution of a supply reel (12) in a tape transport, a second pulse generator (38) for generating n second pulses for each revolution of a take-up reel (14), and a counter (44 to 48) for counting the number of the first pulses during one period of the second pulse. The ratio of count value change in the counter for a time period from the start to the end of the tape running is expanded to the square of the change ratio of rotational speed of the reel from the beginning to the end of the tape winding. A counting range of the counter at this time is proportional to m/n.

摘要： This invention is for a tape cassette having window for insertion of a magnetic head and a pinch roller formed extending from a peripheral wall of the housing of the tape cassette to one of the holding plates which holds a pair of reel hubs in place. The device according to this invention has a shutter member, and a resilient metal wire housed in the housing. The shutter member has projections which are to be engaged with an engaging member provided on a tape cassette holder member of the magnetic tape transport apparatus. The metal wire urges the shutter member to close a portion of the window formed in the holding plate. When the cassette is loaded into the loading member, the projections engage with the engaging member and the shutter member releases the closing state of the holding plate forming portion of the window against an urging force of the wire. When the cassette is removed from the loading member, the shutter member closes the holding plate forming portion to prevent the tape from being damaged by an external force.
