Abstract: A metal plate of a recording tape cartridge is provided with a tapered portion at an outer circumference thereof. In a state in which the metal plate is attached at a fixed-side mold plate of a metal mold for molding a reel hub and a lower flange, a gap is formed between the tapered portion and the fixed-side mold plate. During molding, molding material flows into the gap. Because of this gap, an annular pawl portion is formed at the reel hub, which annular pawl portion integrally joins the metal plate with the reel hub by sandwiching the metal plate via the tapered portion.

Abstract: 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.

Abstract: A cassette 5 with longitudinal and transverse dimensions similar to each other is housed in a cassette storing case which can prevent housing of a cassette into the housing case in an incorrect direction and identify a dedicated cassette storing case corresponding to a cassette, while assuring the function of preventing positional shift during stacking. The cassette storing case 1 includes an indicating portion 15 provided on the top surface 1a of the housing case. The indicating portion 15 has a protrusion-and-recess pattern, similar to a design on the cassette, which indicates a housing direction. The cassette storing case 1 further includes a stopper portion 17, provided on the bottom surface 1b of the housing case, for engaging with part 16 of the indicating portion 15 to regulate positional shift when housing cases are stacked with each other.

Abstract: 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.

Abstract: 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.

Abstract: A magnetic tape cartridge includes a cartridge casing formed by upper and lower casing halves and a single reel around which a magnetic tape is wound and which is contained in the cartridge casing for rotation. A slide door for opening and closing a tape outlet opening is mounted on the cartridge casing to be linearly slidable along a door passage between a closing position where it closes the tape outlet opening and an opening position where it opens the tape outlet opening. A door spring for urging the slide door toward the closing position and holding the same in the closing position is disposed on the door passage.

Abstract: Disclosed herein is a magnetic tape cartridge including a cartridge case. In the cartridge case, a single reel with magnetic tape wound thereon is rotatably housed, and a leader pin coupled with a leading end of the magnetic tape is caught by a pin catching member of a recording-reproducing unit and is inserted into a tape leader opening formed in the cartridge case. The magnetic tape cartridge also includes a pin retaining spring member which elastically engages the leader pin so that the leader pin is detachably retained at a predetermined position within the cartridge case. Furthermore, a wall surface is provided in the cartridge case so that when the leader pin is inserted into the cartridge case, displacement of the pin retaining member due to the engagement of the pin retaining member with the leader pin is regulated within a predetermined range.
