A leader member that is attached to a free end of a recording tape wound around a single reel accommodated in a case and that is pulled out from an opening formed in the case by an pull out member of a drive device is manufactured by die casting with one of a zinc alloy, an aluminum alloy, a magnesium alloy, or a copper alloy.

Abstract: A recording tape cartridge includes a reel, a case where the reel is accommodated, an engagement gear that is provided in the reel, and a brake gear which is provided in the case side brake member and in which a mesh state with the engagement gear or a mesh release state with the engagement gear is switched by relative displacement of an axis line direction of the brake member with respect to the reel. In a piece taper tooth of the engagement gear, a mesh surface that is oriented in a winding rotation direction is approximately parallel to a reel axis line direction and an opposite mesh surface is inclined with respect to the reel axis line. A piece taper tooth of the brake gear is a taper tooth that is opposite to the piece taper tooth of the engagement gear.

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.

Abstract: A tape reel including: a substantially circular cylinder shaped hub; flanges provided as separate bodies from the hub at both end portions of the hub; a connecting member connecting together the flanges at the inside of the hub, in a non-contact state with the inner peripheral face of the hub. The recording tape is wound on the hub in such a manner that the side of the recording tape with the smaller radius of tape edge curvature is on the smaller diameter side of the hub. Also disclosed are: a recording tape cartridge housing such a tape reel; a take-up reel provided in a drive device; a drawing-out member, housed in the hub of a take-up reel and on which recording tape drawn-out from a recording tape cartridge is wound; and a drive device with take-up reel and drawing-out member.

Abstract: In a tape reel that includes a hub around which recording tape is wound and flanges disposed on both end portions of the hub, the elastic modulus in a radial direction of the hub is equal to or greater than 16.0 GPa, and the hub includes different radii on one end side thereof and another end side thereof. The recording tape is wound around the hub such that the side where the radius of curvature of the curvature of a tape edge of the recording tape is small corresponds to the small radius side of the hub. When the recording tape is wound around the hub, fluctuation of the recording tape in an axial direction of the hub is controlled, and one-layer protrusion and disorderly winding of the recording tape that has been wound around the hub are controlled.

Abstract: A paper magazine to be loaded in an image recording device contains a roll of recording paper, and is provided with a transport mechanism to feed the recording paper out of the paper magazine with holding a leading end of the recording paper. The transport mechanism includes a drive roller and a belt mechanism. The belt mechanism is composed of a pair of pulleys, separated by a particular interval, and a flat belt to encircle the pulleys. The drive roller contacts with the flat belt in the center, pressing it to bend. Making surface contact with the recording paper between the flat belt, the drive roller transports the recording paper without slipping.

Abstract: The invention proposes a tape drive apparatus, tape extraction apparatus and tape cartridge that enable a reliable chucking and chucking release, and a stable carrying of a tape being extracted from a cartridge.

Abstract: A recording material roll is constituted by winding thermosensitive recording material of paper.
