Description

[Detailed description of the invention] [Field of industrial application] The present invention is a hard disk, especially a double-sided hard disk, housed in a case.
It is related to cartridges.

[Conventional technology]

Generally, a compact disc (CD) or video disc (LD) as an information recording carrier is taken out of its packaging case and set in a recording/playback device such as a disc player for use.

[Problem that the invention attempts to solve]

Conventional disks of this type tend to collect dirt and dust when handled, are particularly susceptible to damage, and are also affected by temperature changes, so it is necessary to protect the disks from this, and for this reason, a tray system or cartridge system has been adopted. However, if a double-sided hard disk is stored in the disk storage area of the tray or case, the disk will come into contact with the case and the above requirement cannot be met. During transportation, the recording surface of the disk could become dirty or damaged by contact with the inner wall of the case, and the recording surface could be easily affected by temperature, as well as being complicated to handle. .

The present invention aims to eliminate these conventional drawbacks.The purpose of this invention is to keep the disc suspended in the case except when driving the disc, so that the recording surface of the disc does not come into direct contact with the case. The aim is to provide a disk cartridge that can be safely stored inside a case.

The present invention has a case A consisting of a disk 3 and an upper case 1 and a lower case 2 for rotatably housing the disk 3, and a window 4 formed in the case A for inserting a recording/playback head can be opened and closed. A disk case A equipped with a shutter 5, an operating member 6 for locking or releasing the shutter 5, and a disk receiving member 7 connected to the operating member 6 and receiving the upper and lower surfaces and the outer peripheral end surface of the disk 3. In the cartridge, the actuating member 6 is provided with a lock portion 6 ₁ of the shutter 5 and a guide groove 6 ₃ , and the guide pin 10 of the disk receiving member 7 pivotally connected to the support shaft 11 is loosely fitted into the guide groove 6 ₃ . The disk receiving member 7 is made to move toward and away from the disk 3 by the sliding movement of the operating member 6, and when the shutter 5 is closed, the disk 3 is held at approximately the center in the thickness direction of the case while being biased toward the rear side of the case. The disk cartridge is also characterized in that a lock portion ₆₁ is arranged to engage with the shutter 5.

〔Example〕

The present invention has a case A consisting of a disk 3 and an upper case 1 and a lower case 2 for rotatably housing the disk 3, and a window 4 formed in the case A for inserting a recording/playback head can be opened and closed. The case A is equipped with a shutter 5, an operating member 6 for locking or releasing the shutter 5, and a disk receiving member 7 connected to the operating member 6 and receiving the upper and lower surfaces and the outer peripheral end surface of the disk 3. The actuating member 6 is made slidable in the cartridge insertion direction, and the sliding movement of the actuating member 6 allows the disk receiving member 7 to move toward and away from the disk 3, so that when the shutter 5 is closed, the disk 3 is moved approximately to the center of the case in the thickness direction. The disc 3 is supported in a suspended state within the case A by being biased toward the rear side of the case while being held in the same position, and the disc receiving member 7 is separated from the disc 3 when the shutter 5 is opened. It is arranged to do so.

The shutter 5 consists of a clamping plate with a U-shaped cross section that is slidably fitted along both surfaces of the upper and lower cases 2 of the case A, and has a hook-shaped member for locking the operating member 6. The lock part 61 is connected to the lock part ₆₁ .

The operating member 6 is an operating lever for operating each operating section, and has a hook-shaped lock portion ₆₁ at one end that locks the shutter 5, as shown in FIG. 3 and FIGS. 7 to 9. The side surface of the actuating member is provided with an operating piece 6 ₂ that protrudes from the operating piece sliding notch 12 formed on the side wall of the case A, and the operating piece sliding notch 12 is connected to the side wall of the case A. A guide groove ₆₃ is provided which extends integrally with the covering closing wall part ₆₄ and into which the guide pin 10 which serves as the connection part of the disk receiving member 7 is loosely fitted. A pair of spring members 8 are provided facing each other near both sides of the front side, and each is slidably fitted into a groove or gap in the case, and is engaged with the spring receiving part 14 and the spring supporting part 13. is biased toward the front insertion side of the cartridge.

Further, as the disk receiving member 7, the fourth to fifth disk receiving members 7 are
As shown in the figure, it also serves as a lifter for lifting the disk 3, and has a U-shaped cross section with a recess ₇₁ along the outer periphery of the disk 3.It is rotatable on a support shaft 11 and allows for slight vertical movement. A pair of elastic members 9 are provided inside the case to face each other on the case insertion side, and are provided with elastic members 9 on surfaces that contact the outer circumference of the disk, for example, on the inner surface of the recess ₇₁ , or on the upper and lower surfaces as necessary. This elastic member 9 is made of rubber or polyethylene.
It is preferable to use a material made of a soft plastic material such as polypropylene or vinyl chloride, which is useful for preventing rattling of the disk 3 and preventing damage to the outer periphery of the disk.

The approximately U-shaped tip formed at one end of the disk receiving member 7 has a concave portion ₇₁ whose inner upper and lower surfaces are formed into a tapered inclined surface ₇₂ or a rounded curved surface so that the disk 3 can be used as a tapered tongue. The guide pin 10 is protruded from the other end of the guide groove 6 of the actuating member 6 so that it can be easily inserted into the recess 7 ₁ .
Although the guide groove ₆₃ and _the guide pin 10 are provided in a relative relationship, they may be provided in the opposite manner.

Further, as the spring member 8, a coil spring may be tensioned in the sliding direction of the operating member 6, a coil spring may be tensioned between the interlocking disc support member 7 and the case fixing part, or a coil spring may be tensioned between the interlocking disc support member 7 and the case fixing portion, or a coil spring may be tensioned between the interlocking disc support member 7 and the case fixing portion. It is also possible to wrap a coil spring around 11 to provide a restoring force, and in any case, the actuating member 6 is biased toward the front insertion side.

Further, in this embodiment, as shown in FIG. 6, on the rear surface side opposite to the front surface on the insertion side of the cartridge, at least a part of the inner side of the case against which the stored disk is abutted is placed on the inner bottom surface of each case 1, 2. 1
Slanted surface portions 1 ₂ , 2 ₂ are provided from ₁ , 2 ₁ toward approximately the center in the thickness direction of the case so that the disk 3 is guided to the center, and is shown as a solid line when stored, and as a chain line during operation. Become.

These inclined surfaces 1 ₂ , 2 ₂ have slippery disk holding members 1 ₃ , 2 ₃ made of ultra-high molecular weight polyethylene, ultra-high molecular weight polyethylene foam, or graphite Teflon polyester (PET).
Alternatively, select a sheet of metal such as stainless steel to attach the inner bottom surface 1 ₁ of the upper case 1 and the tongue case 2,
2 _{and 1} may be attached and fixed facing each other.

In the figure, 1 ₄ and 2 ₄ are concave surfaces formed on the inner bottom surface of the case and are formed in the movement range of the disk receiving member 7.

Reference numeral ₆₄ denotes a closing wall portion, which is provided on the operating member 6 and is used as a dustproof cover piece for blocking dust from entering the case A through the operation piece sliding notch 12.

₁₁₁ is a pedestal that supports the disk support member 7.
15 is a screw, 16 is a groove, 17 is a slippery adhesive sheet, and 18 is a rib.

When the disc/cartridge is inserted and set into the disc player, the operation pieces ₆₂ protruding from both sides of the cartridge engage with the protrusions of the insertion opening, and the operation pieces ₆₂ slide toward the rear side of the cartridge. By this sliding of the operating member 6, the shutter 5 is released from the hook-shaped lock portion ₆₁ of the operating member 6, and the shutter 5 is moved in the window opening direction by an opening/closing mechanism (not shown) within the device to the open position. At the same time, the disk receiving member 7 rotates around the support shaft 11 to release the disk held away from the disk 3 in the case A, and the disk is moved to the sliding surface at the inner bottom of the disk storage area. It is safely supported on the adhesive sheet 17 and then held in engagement with a drive member (not shown) within the device. On the other hand, when taking out the cartridge from the disk player, the disk 3 is disengaged from the drive member within the case and supported on the slippery adhesive sheet 17, and then the shutter 5 is moved in the closing direction to open the window 4. In addition to being in a closed state,
The actuating member 6 slides toward the front insertion side by the spring member 8, interlocks the disk receiving member 7, and inserts the disk 3 into the recess ₇₁ , so that the disk 3 is raised to approximately the center in the thickness direction of the case. While holding the disk 3, the disk 3 is supported by being biased toward the rear side opposite to the case insertion side, and at the same time, the shutter 5 is held closed by the lock portion ₆₁ . Therefore, the recording surface of the disk 3 is not rubbed and scratches are prevented from occurring, allowing safe use, and even during handling, the disk 3 is guided to the center position within the case and can be kept floating in the air.

[Effect of idea]

In the present invention, the actuating member 6 is provided with a lock portion 6 ₁ of the shutter 5 and a guide groove 6 ₃ , and a guide pin 10 of the disk receiving member 7 pivotally connected to the support shaft 11 is loosely fitted into the guide groove 6 ₃ . The disk receiving member 7 is made to move toward and away from the disk 3 by the sliding movement of the operating member 6, and when the shutter 5 is closed, the disk 3 is held at approximately the center in the thickness direction of the case, and the shutter 5 is provided with a locking portion _61. By sliding the operation piece of the actuating member located on the side wall of the case, the locking part of the actuating member moves, the shutter is unlocked, and the shutter can be opened. As the disk receiving member rotates around the support shaft in conjunction with the sliding movement of the operating member,
In conjunction with this, the tip of the disk receiving member rotates, and the disk is released from the disk receiving member and can be inserted into the drive shaft of the device, making it possible to record and play back on the device. Since only the non-recording surface part is held in the case in a floating state by the disk support member, it can be used safely without affecting the recording surface part, and it also prevents play in the circumferential direction of the disk and in the case thickness (top and bottom) directions. In addition to making it possible to accurately prevent problems, it is also possible to reduce the number of parts and reduce costs.
