A tape cartridge has a right and left pair of reels 3 around which a tape 2 is wound, within a casing 1 equipped with a front cover 7. A reel lock mechanism 19 is provided within the casing 1 for preventing the reels 3, 3 from rotating. A release member 30 is disposed on the inner, upper face of the bottom wall of the casing 1 so as to be movable back and forth. A slider 9 for opening and closing the lower face of the pocket 6 for tape loading is fitted to the outer, lower face of the bottom wall of the casing 1 so as to be movable back and forth. When the slider 9 moves backward, the release member 30 is moved backward nearly at the terminating end of the backward travel stroke of the slider 9. With the backward movement of the release member 30, the reel lock mechanism 19 is moved, thereby releasing the reels 3, 3 from locking for rotation. Thus, while the front cover 7 is kept from any excessive upward opening force, the reels 3, 3 can be locked and released for rotation by the movement of the slider 9.

A tape guide mechanism for a VTR includes a pair of first guides (5,6) disposed respectively at a tape entrance side and a tape exit side of a cylinder and positioned immediately adjacent to the cylinder, a pair of second guides (7,8) disposed adjacent to the pair of first guides, respectively, and a third guide (14) provided in a path of travel of a tape extending between the first guides and the second guides, so as to prevent opposed surfaces of the tape, disposed respectively at the tape entrance side and the tape exit side, from being contacted with each other. The third guide may be of a rotary type and be disposed remoter from the cylinder than the first guides.

A first tape guiding plate positioned close to a cylinder on a tape entrance side and a second tape guiding plate positioned closer to a supplying reel than the first tape guiding plate, are connected to a loading ring, and a connecting part of the second tape guiding plate to the loading ring is movable along the loading ring. The distance along the loading ring between the connecting parts of the second and first tape guiding plates to the loading ring is variable. The distance between the first and second tape guiding plates can be set sufficiently long during loading and sufficiently short during unloading.

Signal-recording/reproducing apparatus for use with a tape cassette includes a cylinder having mounted thereon heads for recording and reproducing a signal on and from a magnetic tape within the tape cassette, respectively. A pair of tape guides are movable between an unloading position remote from the cylinder and a loading position adjacent thereto. The tape is withdrawn out of the tape cassette by the tape guides when they are moved from the unloading position to the loading position. When the tape guides are in the loading position, an angular extent over which the tape is in contact with a non-rotatable guide element of one of the tape guides located at a leaving side where the tape leaves the cylinder is less than that over which the tape is in contact with a non-rotatable guide element of the other tape guide located at an approaching side where the tape approaches the cylinder.

A signal recording/reproducing apparatus for use with a tape cassette comprises a cylinder assembly having an outer peripheral surface. The cylinder assembly has mounted thereon heads for recording and reproducing a signal on and from a magnetic tape in the tape cassette, respectively, and a lead formed on the outer peripheral surface of the cylinder assembly so as to helically extend, to define a running path of the magnetic tape on the outer peripheral surface of the cylinder assembly. A pair guides guide the tape so that the tape is helically wound over a predetermined angular extent along the lead upon the recording/reproducing of the signal. The pair of tape guides are located and oriented in their predetermined positions such that the tape guides impart a force to the tape to press the tape onto the lead during recording and reproduction thereby to permit the tape to move along the lead.

A magnetic tape cassette having tape reels on which a magnetic tape is wound, includes magnetic tape regulating members one end portions of which are securely fixed on the magnetic tape cassette, other portions thereof being in contact with edge portions of the magnetic tape so as to regulate side edge alignment of the magnetic tape in the magnetic tape cassette. Thus, it is possible to prevent tape damages such as tape edge folding caused by side edge misalignment of the tape in the cassette.
