Abstract

PURPOSE:To improve the dustproof effect of a disk when a cartridge is used by providing the opening/closing mechanisms which are independent of each other to the upper and lower shutters which open and close an access hole on a disk surface. CONSTITUTION:A hole 4 for recording/reproducing, a shutter opening/closing detecting hole 5, etc. for access to the surface of a disk 8 are provided to the upper and lower covers 1 and 2, respectively. These holes 4 and 5 are opened and closed by shutters 7, and the opening/closing of these shutters is controlled by shutter opening/closing band-shaped members 10 which are independent of each other. The shutter 7 at the surface side of a disk 8 which is not used when a cartridge is inserted to a recording/reproducing device is not opened. Thus the dustproof effect of a disk is improved when a cartridge is used.

This hole needs to be relatively large, and it is desirable to have a structure that can be closed with a shutter to prevent dust from entering through the hole when removed from the recording/reproducing device. When both sides of the disc are information recording surfaces, the shutters mentioned above are attached to both the top and bottom of the cartridge, but these shutters do not allow the cartridge to be used as a recording/playback device. It is desirable that the cartridge can be opened and closed with light force when it is attached to and detached from the cartridge, and that the cartridge has a structure that is easy to assemble.

FIG. 1 shows an exploded perspective view of a cartridge for an optical disk, which is an embodiment of the present invention. A hole 5 for rotating the disk 5, a hole 4 for recording and reproducing to make the optical head face the disk 8, a hole 5 for detecting the opening and closing of the shutter 7, and a guide 6 for defining the moving path of the shutter opening member 9 are provided. A ring-shaped projection 13 is formed on the inner surface of the disk rotation hole 3, and the chassis turf is rotatably supported here. The shutter 7 has an ear flap 1 at the tip.
2, and this lug moves in conjunction with the movement of the shutter 7,
The opening/closing detection hole 5 is opened/closed. Reference numeral 9 denotes a belt-shaped member for opening and closing the shutter 7, one end of which engages with the shutter 7, and the other end of which extends to the outside of the car and is connected to the shutter release key 10. This band-shaped member 9 is normally given a force in the direction in which the shutter closes the recording/reproducing hole 4 by a return spring 11 that is fixed to the inner surface of the cover. The cartridge of this embodiment consisting of these elements has the shutter 7, the strip member 9, the shutter release key 1o, and the return spring 11 p attached to each cover 1.2 to form a single assembly, and can be used for earthworks with the same structure. The disk 8 is inserted into the assembly and assembled together by screwing or gluing.

2(B) are diagrams for explaining the movement of the cover when inserting the disk cartridge 16 shown in FIG. 1 into a recording/reproducing apparatus, and are sectional views showing half of the cartridge. When the force cartridge 16 is inserted along the cartridge receiving part 15 provided on the recording/reproducing device side,
A protruding member 114 provided on one side of the cartridge receiving portion 15 engages with the shutter release key 10 facing the protruding member 114, and one of the strip members 9 is pulled out along the guide 6 in conjunction with the cartridge insertion operation. . As a result, the chassis turf on the side facing the optical head rotates, and the recording/reproducing hole 4 and the open detection hole 5 are closed. At this time, since there is no protruding member for opening the shutter on the other side of the cartridge, the shutter on the side opposite to the optical head is opened. ○When the cartridge is inserted in this way.

On the recording/reproducing device side, it can be confirmed by a transmission type sensor or the like that the open detection hole 5 is open and there is a ball. Therefore, by proceeding to the next operation with this confirmation signal as a condition, it is possible to prevent damage caused by collision between the recording/reproducing head and the shutter 7 when the disk 8 is fixed to the hub.

As is clear from the above description, according to the present invention, by moving the shutter along the guide on the inner surface of the cartridge, it is possible to prevent the rotation of the disk and the disk when the cartridge is installed in a recording/reproducing device. It is possible to record and play back information on the disk, and protect the disk from dust and damage when not installed. However, when installed in a recording/reproducing device, only one of the front and back shutters facing the optical head is open, and the other shutter is closed.
This prevents dust from entering and damaging the disk surface on the non-access side. Furthermore, according to the present invention, the cover and accessory parts can be used as a cart.
