    摘要: An attachment structure for a tape body which supports, on reel hubs, a tape body such as a leader tape, etc. to which a magnetic tape is connected. This attachment structure comprises a tape reel provided with a reel hub which takes cylindrical shape provided at the central portion thereof and a clamp member attached to the reel hub, and a tape body connected to the reel hub in the state where the end portion is supported by the clamp member and wound on the outer circumferential surface of the reel hub. The tape body supported by the reel hub is such that the base end portion side serving as root portion of the drawing side from the reel hub is deformed in the winding direction onto the reel hub following the outer circumferential surface of the reel hub. Deformation of the tape body is carried out by thermal deformation or pressure deformation, or thermal deformation and pressure deformation. The root portion serving as the supporting portion side onto the reel hub of the tape body is deformed following the outer circumferential surface of the reel hub, whereby the tape body is wound in the state closely in contact with the outer circumferential surface of the reel hub.

    摘要: A tape cartridge includes a front lid rotatably mounted to a casing for closing a tape loading space thereof, a back lid rotatably mounted to the front lid and including a hood for closing a back-lid opening of the casing and a leg for protecting the back of a magnetic tape positioned in the tape lading space of the casing, an inclined face arranged on the upper side of the hood of the back lid to be adjacent to the casing, and a device for controlling a posture of the back lid. In the state of closing the back-lid opening of the casing, the inclined face gradually increases in level difference with respect to the upper side of the casing toward the casing.

    摘要: An acylated cellulose film having a high optical isotropy and uniformity is produced by dissolving an acylated cellulose in a solvent substantially free from water and including, as a principal component, 1,3-dioxolane in a ratio in weight of the acylated cellulose to the solvent of 10/250 to 10/15; spreading the acylated cellulose solution on a film-forming surface of a support; and drying, for example, initially drying the spread solution layer on film-forming surface so as to reduce the content of the residual solvent in the resultant film to 5 to 30% by weight; removing the resultant residual solvent-containing film from the film-forming surface; and finally drying the removed film, while allowing the film to shrink in the transversal direction thereof, at a drying temperature controlled continuously or intermittently to a level satisfying the relationship (I): (Tg'-50.degree. C.).ltoreq.T.ltoreq.(Tg'+20.degree. C.) (I), wherein T is the drying temperature (.degree.C.) and Tg' is a glass transition temperature (.degree.C.) of the solvent-containing film, the temperature Tg' varying in response to the solvent content in the film.
