Abstract
A disk cartridge has a casing composed of upper and lower casings which are adapted to rotatably receive therein a disk-like medium a shutter attached to the casing so as to open and shut openings for driving shaft insertion holes and magnetic head insertion holes formed in the upper and lower casings a disk-like medium taking-out port formed in the casing and a cover member for opening and closing the disk-like medium taking-out port wherein the cover member is disposed in the casing at a position opposing the shutter a disk-like medium placing portion is provided by forming tongue-like projections in the cover member to support the disk-like member from its lower surface side; the cover member is so arranged as to slide between the upper and lower casings whereby the disk-like member can be taken out by simply drawing the cover member from the disk-like medium taking-out port or the disk-like medium can be placed by simply inserting it, and operability in exchanging the disk-like medium can be done extremely well. The lower casing is so constructed that a recessed face portion for receiving the tongue-like projections formed in the cover member is formed in an inner face which opposes the disk-like medium whereby the strength of the casing can be well maintained; easy taking-out and insertion of the disk-like medium are permissible, and good operability of exchanging the disk-like medium is obtainable.
