A tape loading gear is in facing relation to the cut-out in the first drive gear until the tape cassette moves to its loading position.

Abstract: In a signal recording-reproduction apparatus having a reel chassis slidably mounted on a main chassis, a reel support drive device transmits the rotation of a capstan motor serving as a power source to one of two reel supports through a swing idler mechanism on the main chassis and through a gear mechanism on the reel chassis. The gear mechanism includes at least two gears rotatable in the same direction and arranged along the sliding direction of the reel chassis. As the reel chassis slides along away from the head cylinder of the apparatus, an idle gear comes into meshing engagement with each of the two gears one after another to continue the rotation of the above reel support, whereby the magnetic tape pulled out around the head cylinder is wound up inside the tape cassette during the sliding movement of the reel chassis.

Abstract: A magnetic tape is withdrawn from a tape cassette, wound partly around a rotatable drum with transducer heads through a predetermined wrap angle, and fed along for recording signals on and reproducing signals from the tape with the transducer heads. A pair of skew blocks is fixedly disposed laterally of and near the rotatable drum. A pair of vertical guide rollers is movable from a first position in which they are positioned within an opening defined in the tape cassette and behind the tape in the opening to a second position near the skew blocks. When the vertical guide rollers are moved from the first position to the second position, the vertical guide rollers withdraw the magnetic tape from the tape cassette and hold the magnetic tape against the rotatable drum and the skew blocks. The magnetic tape extending between the skew blocks is skewed by the skew blocks to allow the transducer heads to scan the magnetic tape at a prescribed skew angle.

This upper limit can be varied, depending on various operating modes. When an abnormality is detected, the brake of the reels is driven and the rotation of the drum is stopped. After the tape has been stopped, the tape is unloaded while rotating the supply side reel and the take-up side reel, the drum remaining not rotated.

Abstract: Tape guides of a magnetic tape transport machine are controlled during movement by sensing the position of the member as it moves along a defined path in varying velocity corresponding to the position. The member is initially accelerated at a selected rate to a maximum velocity which is then maintained until a distance close to the end position is reached. Velocity is then reduced at a selected rate until another position closer to the end position is reached. At this position a final velocity is maintained until the end is reached. A determination is made of how closely the second distance from the end coincided with reaching the final velocity. The length of the first distance from the end position is adjusted to reduce the difference between the coincidence of reaching the second distance and the final velocity. Further, the sensed final position of the member is retained as the target final position for the subsequent operation.

Abstract: To provide for controlled tape tension during pull-out of tape (11) from a cassette into a preliminary pulled-out position, placement of the tape in a transducing path (11a) and subsequent operation of the tape in the transducing path, two tape loading elements (21,22) are movably located on a support (65a) to engage behind the tape (11) in the cassette (12) and move the tape out of the cassette and towards the transducing path.
