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.

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 magnetic cassette tape record and play apparatus wherein the magnetic head thereof is fixed, comprises a push member cooperating with an operation button and which is so disposed as to abut against a pad spring received in a tape cassette. When the tape cassette is loaded or ejected in the stop mode, the push member is pressed against the pad spring to deform it against its urging force, thereby locking the cassette tape in a position untouched by the magnetic head. When the operation button is depressed for the recording or reproduction mode, then the push member is removed from the pad spring, thereby causing the pressure pad to be pressed against the magnetic head with the cassette tape disposed between the pressure pad and the magnetic head.

摘要： Within a housing of a tape cassette is mounted a reel hub serving to wind a magnetic recording tape. The reel hub is moved between a first position where one side edge of the tape wound around the reel hub is spaced from a wall of the housing and a second position where the one side edge of the tape abuts against the wall, reel hub being rotated at the first position by a reel shaft of a magnetic recordig tape running apparatus inserted through an opening of the wall of the tape cassette for engagement with the reel hub. Within the housing is also mounted a abutment member. The abutment member is movable between a third position where the abutment member is spaced from the other side edge of the tape wound around the reel hub located in the first position and a fourth position where the abutment member abuts against the other side edge of the tape wound around the reel hub located in the second position by the reel shaft inserted through the opening of the tape cassette housing for engagement with the reel hub. The abutment member is usually urged to the fourth position by a compression coil spring housed in the tape cassette housing.

摘要： A device for stably running a magnetic recording tape of a tape cassette comprises a reel shaft and a motor connected to the reel shaft. The reel shaft and the motor make a running of the magnetic recording tape providing back tension exerted on the magnetic recording tape. Within the housing of the tape cassette, a first lever having one end rotatably fixed to the housing is mounted. A guide roller for guiding the running direction of the tape is rotatably fixed to another end of the first lever. Therefore, the first lever may swing in response to a back tension exerted on the tape. An amount of the swing of the first lever is detected by a second lever which is rotably located out of the housing and selectably engaged with the first lever. The second lever is connected to the detection means which generates an electric signal in accordance with the amount of rotation of the second lever. The electric signal is sent to the electric controlling circuit means electrically connected to the motor. The electric controlling circuit means controls a value of the voltage supplied to the motor in accordance with the electric signal, and stabilize the value of the back tension exerted to the tape via the motor and the reel shaft.

摘要： A tape running direction indicator is provided with a sensor for producing a sense pulse corresponding to the rotation of a take-up reel, a ring counter clocked by the sense pulse, and a display unit which receives output pulses of the ring counter and includes decimal points arranged side by side for indication of the tape running direction. The output pulses of the ring counter are shifted corresponding to the direction of the tape running. A glint of each decimal point is successively shifted in the direction of the tape running while flashing.
