  • Patent number: 7841554
    Abstract: A recording tape cartridge can prevent release of rotation locking of a reel with respect to a case accompanying dropping of the recording tape cartridge. The tape recording cartridge is configured to rotatably accommodate within a case a reel that has magnetic tape wound on a reel hub. Within the reel hub, external teeth of a brake gear, of a brake member that is supported so as to be non-rotatable with respect to the case, mesh with an engaged gear having internal teeth, preventing rotation of the reel with respect to the case. Lock portions of lock members are inserted between the reel positioned biased to a bottom panel side by a compression coil spring, and a top panel, thereby preventing movement of the reel with respect to the case in the reel axial direction.

  • Patent number: 7832674
    Abstract: A tape cartridge has a tape housing, first and second reel member cooperate with each other to constitute a reel around which a tape is wound, a connecting and biasing member connecting between the first and second, and first and second engaging means. The first engaging means is provided on an inner surface of the lower wall. The second engaging means is provided on a lower surface of the second reel member. This arrangement allows that the second engaging means can engage with the first engaging means due to a biasing force caused by the connecting and biasing member to prevent a rotation of the second reel member and can disengage from the first engaging means when the drive shaft accesses the second reel member through the opening and forces the second reel member toward the first reel member against the biasing force of the connecting and biasing member.

  • Publication number: 20100065671
    Abstract: A recording tape cartridge is equipped with a reel around which is wound recording tape and an upper case and a lower case that house the reel. Ribs whose rib height gradually becomes lower from a center side of the reel toward an outer peripheral side of the reel are formed on an inner surface of the upper case. Edge portions that slant linearly from the center side of the reel toward the outer peripheral side of the reel are formed on the reel side of the ribs. The distance of the space inside the case in the thickness direction of the recording tape cartridge is wider on the outer peripheral side of the reel in comparison to the center side of the reel, so it is difficult for the recording tape inside the case to sustain damage even if the recording tape cartridge receives an impact.
