摘要： A mold for forming a magnetic tape cassette and a method for multi-color molding a magnetic tape cassette or the like. Sprue-runners connected to submarine gates used in making at least portions of the cassette are formed with notches near the submarine gates to reduce the cross-sectional area of the sprue-runners. As result, the sprue-runners can be easily cut off from the body of the cassette by breaking the notched portions.

摘要： A magnetic tape cartridge includes a cartridge casing and a single reel which is contained in the cartridge casing for rotation. The reel has a reel hub in the form of a cylindrical member which has a bottom wall and is provided with an opening and a stopper gear formed on the bottom wall. A brake member is provided with a brake gear and is movable up and down between an operative position where the brake gear is brought into engagement with the stopper gear to prevent rotation of the reel and a retracted position where the brake gear is disengaged from the stopper gear to permit rotation of the reel. The brake member is normally urged toward the operative position and moved to the retracted position by a pusher member of a tape drive system which acts on the brake member through the opening in the reel hub when the magnetic tape cartridge is loaded in the tape drive system. A continuous wall portion is erected around the opening in the reel hub, and the brake member includes a horizontal portion and a continuous skirt portion which extends downward from the horizontal portion and is in contact with the continuous wall portion of the reel hub to close the opening together with the horizontal portion. The brake member is moved between the operative position and the retracted position with the skirt portion kept in contact with the continuous wall portion of the reel hub.

摘要： Disclosed herein is a magnetic tape cartridge comprising a single reel with magnetic tape wound thereon, a cartridge case for rotatably housing the single reel, a leader pin having a tape clamp portion on which the magnetic tape is wound, and a clamp member with a C cross section that has an axial slit. The leader pin is affixed to a leading end of the magnetic tape by elastically fitting the clamp member onto the tape clamp portion of the leader pin. A sheet member for enhancing a coefficient of friction is interposed at least between the magnetic tape and the tape clamp portion.

摘要： A magnetic tape cartridge with an improved reel-rotation restraining mechanism is disclosed. The reel-rotation restraining mechanism has a reel locking member, which is movable toward and away from the reel, for restricting rotation thereof; an urging member for urging the reel locking member in a restraining direction; and an releasing member, which is rotatable integrally with the reel, for moving the reel locking member in an unlocking direction by moving according to a chucking operation of a rotation drive mechanism of a drive unit. The releasing member has three leg portions on the vertexes of a triangular plate portion insertable into through holes in the reel. The releasing member is sized so that with part of the releasing member inserted into a center opening of the reel, and two of the three leg portions positioned near the through holes, the remaining one leg portion can be dropped and inserted within the center opening.

摘要： A magnetic tape cartridge includes a cartridge case, which is formed by fastening upper and lower cases integrally and has a tape leader opening in side walls of the upper and lower cases. Within the cartridge case, a single reel with magnetic tape wound thereon is rotatably housed. A slender leader pin firmly attached to the leading end of the magnetic tape is detachably held near the tape leader opening and between the upper and lower cases. In the magnetic tape cartridge, a small-diameter pin for fastening the upper and lower cases is press-fitted near a holding portion of the cartridge case which holds the leader pin.

摘要： In a magnetic tape cassette, a top end portion of a reel urging plate spring for urging a tape reel is subjected to a surface treatment to prevent from a friction. A distance between a couple of flanges of the tape reel is selected to keep a form of the wound magnetic tape, and to prevent the tape running from being disturbed by the increase of a contact resistance of the tape edges to the flanges. Additionally, positioning portions for positioning the magnetic tape cassette relative to a magnetic tape drive device are formed of a differential resin from the resin of the remaining part of the cassette case. Additionally, at least one of both end faces of each guide roller is surface treated so that the end face is not worn through its contact with the cassette half. Further, an information presenting section for displaying variable information is provided at a location other than label areas of the tape cassette.
