タ機構に改良を加えたものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a disk cartridge in which a disk as a recording medium is rotatably housed in a cartridge case having a head insertion window, and a shutter mechanism for opening and closing the head insertion window. This is an improvement on the .

からごみや塵埃がケース内に侵入してディスク２に付着
したり。Conventionally, as this type of disk cartridge, there is one equipped with a shunter as shown in FIG. In this case, a disk 2 is rotatably housed in a cartridge case 1, and a head insertion window 4 is opened in the cartridge case L. If the head insertion window 4 is left open when not in use, dirt and dust will come out from there. may enter the case and adhere to disc 2.

開かれるようになっている。In addition, problems such as fingerprints from touching the disc 2 may occur. Therefore, a shutter 5 having a U-shaped cross section is mounted on the head insertion window 4 of the cartridge case 1 so as to be slidable in the opening and closing directions. Under normal conditions, a spring member (not shown) applied between the shutter 5 and the cartridge case 1 always biases the shutter 5 in the closing direction, so that when the cartridge is pushed into the drive and loaded, the shutter 5 is opened by the shutter opening operation member on the drive side. It has become.

入や指紋付着の問題が生じる。In this conventional type, since the shutter 5 is always biased by the spring in the closing direction, the shutter 5 is automatically closed at the same time as the opening operation by the shutter opening operation member on the drive side is released. The following difficulties arise. First, when loading a disk cartridge into a drive, the opening operation member on the drive side may not operate smoothly due to, for example, the spring force that biases the shutter 5 to close, or some other reason. The head approaches the head insertion window before the shutter 5 is completely opened, and at this time the head closes the shutter 5.
There is a risk of damage due to contact interference. Second, as mentioned above, the disk cartridge is pushed into the drive side and loaded, but the shutter 5 does not open completely until it reaches the end position of the push. The distance between the head and the pad must be set to a sufficient distance to avoid contact interference between the head and the shutter, which increases the head stroke, especially when the track density is increased. It is difficult to respond (it is very difficult to deal with it).
In order to shorten the head stroke, it is better not to have a shutter, but this causes the problems of dust intrusion and fingerprints as described above.
この発明はかかる事実に着目して、ヘッド損傷防止、並

うにしたものである。That is, assuming that the shutter 5 for opening and closing the head insertion window 4 of the cartridge case 1 is externally mounted on the cartridge case 1 so as to be slidable in the opening and closing direction, the shutter 5 is installed between the cartridge case 1 and the shutter 5. The shutter 5 is provided with means for always biasing a spring in the opening direction, and a locking means that can be switched between a locked state in which the shutter 5 is locked in the closed position and an unlocked state in which the shutter 5 is released. 5 is designed to open.

ヘッドタッチを良好にする。According to the present invention as described above, since the shutter 5 is always biased by the spring in the opening direction, if the shutter 5 is released from the locked state by the locking means due to an artificial source or loading operation to the drive. At the same time, the shutter 5 is automatically opened quickly and reliably. Therefore, shutter 5
In addition, the head insertion window must be closed before the disk cartridge reaches the position between the upper and lower heads or between the head and the pad in the drive. 4
Since the gap between the upper and lower heads can be reduced to the case thickness without a shutter, the head stroke can be reduced by the amount minus the thickness of the shutter, allowing for high-density tracks. To improve head touch even in
