じ用捩りコイルばね。 A torsion coil spring provided in a corner storage space of the disk cartridge urges a shutter for opening and closing a hole in the disk cartridge toward its closed position.The torsion coil spring is wound with an elastic wire. It consists of a coiled part and two arms extending left and right from this coil part, and one arm extends from the coil part to a first extension part extending almost along the circular periphery of the disk, and from this first extension part to the disk car. and a second extension part bent toward the front end wall in the direction of insertion into the recording/reproducing apparatus, the tip of the second extension part engages with the shutter, and the other arm extends from the coil part to the front end wall. The third one extends toward the front end wall.
It consists of an extension part and a fourth extension part that bends and extends from the third extension part in the direction of the side end wall of the disk cartridge, and the tip of the fourth extension part engages with the side end wall of the disk cartridge. , the radius of curvature of the bending part between the third extension part and the fourth extension part is 1.
A torsion coil spring for closing the shutter of a disc cartridge, characterized in that the spring is set within the range of 8 mm to 3 mm.
