Embodiment Construction

[0112] Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. figure 1 is an exploded perspective view of a magnetic tape cassette of one embodiment.

[0113] In the magnetic tape cassette 1, the single reel 4 formed by the combination of the lower reel 5 and the upper reel 6 by ultrasonic welding is wound with a magnetic tape 20, and the reel 4 is accommodated in the upper cover 2 and the lower cover 3 through screws. Installed in the cassette 7 formed together, and can rotate.

[0114] The lower reel 5 is a cylindrical reel core 23 with a magnetic tape 20 wound on its outer periphery, and a flange portion 24 extending radially from the lower end of the reel core 23 is made by integral molding of synthetic resin. A reel plate 8 is installed on the outer surface of the bottom of the reel core 23 to absorb the magnetic rotary drive mechanism for rotating the reel 4 . In addition, a braking gear 23A is engraved o...

Abstract

For accommodating a single reel (4) that can rotate and be wound with a magnetic tape (20) in the magnetic tape cassette (7), the two ends of the guide clip (21) connected with the front end of the magnetic tape (20) are arranged by the sliding door ( 27) The inside of the opening (26) for opening and closing is fixed and held by a bolt (30) that can be combined and disengaged. At least two sides of the inner surface of the sliding door (27) facing the front end of the bolt (30) are provided The concave part (27a) avoids the interference of the two, and realizes stable accommodating action of the guide clip (21) and opening and closing action of the sliding door (27) through the plug part (30), and improves reliability.

Description

[0001] This application is a divisional application, the application number of its parent application: 99809509.5, the filing date: 1999.6.3, the invention name: magnetic tape cassette. technical field [0002] The present invention relates to a magnetic tape cassette, in particular to a magnetic tape cassette containing a single reel that is wound with a magnetic tape and can rotate, and a guide clip for leading out the magnetic tape is fixed at the front end of the magnetic tape, so that the guide clip is accommodated. The structure of the sliding door that opens and closes the opening of the clip and the force-reinforcing structure of the sliding door. Background technique [0003] In a conventional magnetic tape cartridge used as a recording medium of an external storage device such as a computer, a magnetic tape is wound on a single reel, and the reel is accommodated in the tape cartridge so as to be rotatable. This tape cartridge is used to store computer data and reco...
