A magnetic tape transport apparatus including a rotary drum having a plurality of magnetic heads and spaced-apart tape entry and tape exit points; a tape path forming device including two combinations each having one guide roller and one inclined pole disposed respectively at the tape entry and tape exit points of the drum, from which points the magnetic tape begins to contact with and to leave from the drum, respectively, thereby causing the magnetic tape to partially wrap around the cylindrical surface of the drum through a predetermined angular range and to form a magnetic tape transportation path nearby the drum; and an impedance roller disposed at a position between the guide roller and the inclined pole of at least one of the combinations in contact with the magnetic tape; the impedance roller together with one combination of guide roller and inclined pole being disposed close to one of the tape entry and tape exit points of the drum when the magnetic tape is wrapped around the drum and is transported along the magnetic tape transportation path by a tape moving device.

Magnetic tape transport mechanism which absorbs magnetic tape

A guide drum has recording or reproducing heads and a loading device has vertical poles and inclined poles for pulling out a tape from a tape cassette mounted on the recording/reproducing apparatus and for wrapping the tape around the guide drum. The loading device includes a pole driving mechanism for driving the poles and a toggle mechanism for causing a pinch roller to come into contact with a capstan so that the tape is interposed therebetween after the tape is wrapped around the guide drum. The toggle mechanism comprises a pinch roller cam driven in accordance with the movement of the pole driving mechanism, a pinch roller arm having the pinch roller and rotatably supported at one end portion and a link member coupled between the pinch roller cam and the pinch roller arm. With this arrangement, the pinch roller is directed to the capstan in response to the movement of the link member due to the movement of the pole driving mechanism.

Drive mechanism for cassette-enclosed magnetic tape

Disclosed is a magnetic recording/reproducing apparatus including a guide drum having at least one recording/reproducing head and a loading mechanism for pulling out a tape from a tape cassette mounted on the recording/reproducing apparatus and for wrapping the tape around the guide drum. The loading mechanism includes first and second loading devices each having a vertical rotatable pole and an inclined pole and the first and second loading devices are engaged with first and second guide grooves and are moved along the first and second guide grooves. At least one of the first and second guide grooves is branched in the vicinity of the loading termination position into two branch grooves so that the inclined pole of the corresponding loading device is substantially and angularly displaced with respect to the vertical rotatable pole by a predetermined angle in the vicinity of the loading termination position as said vertical rotatable pole reaches said loading termination position so as to form a predetermined tape path.
