Description

disk receiving adapter

technical field

The present invention relates to an adapter, such as an adapter adapted to fit a disc with a diameter of 8 cm to be received by a disc drive that accepts a disc with a diameter of 12 cm, and in particular to an adapter including a detection hole for determining the disc size and a device for driving the adapter Methods and Apparatus.

Background technique

Generally, optical discs are roughly divided into two types: discs with a diameter of 8 cm (hereinafter referred to as 8 cm discs) and discs with a diameter of 12 cm (hereinafter referred to as 12 cm discs). Generally, discs of different sizes are dedicated to disc drives that can accommodate their sizes. However, the adaptability of today's disk drives has become an important factor in determining market conditions. Accordingly, there has been a strong demand to make both 8cm disks and 12cm disks usable with disk drives that only accommodate 12cm disks.

In order to meet this requirement, an adapter has been developed which includes a main body as large as a 12 cm disc cartridge for receiving a 12 cm disc and a disc holder which holds and supports an 8 cm disc within the adapter main body. Thus, an 8cm disk in an adapter having the same size and configuration as a 12cm disk cartridge can be used with a 12cm disk drive when the 8cm disk is secured on the disk holder inserted into and within the adapter body.

Figure 1 shows an example of a common adapter.

Fig. 1 is a plan view of a general adapter structure. In Figure 1, element 1 is the adapter body, element 2 is the disc, element 3 is the disc holder and element 4 is the adapter cover.

As shown in FIG. 1 , an adapter main body 1 is as large in size as a 12 cm disc cartridge, and a disc holder 3 to which a disc 2 is fixed is inserted into the adapter main body 1 . The adapter 1 has the same size and structure as the 12cm disc cartridge, the only difference between this adapter and the 12cm disc cartridge is that an 8cm disc is received in the adapter.

The disc holder 3 is formed with first, second and third support sections 3a, 3b and 3c respectively for supporting the disc 2, and the first, second and third support sections 3a, 3b and 3c are formed from the sides of the disc 2, respectively. Disc 2 is supported below. When the disk holder 3 is inserted into the adapter body 1 and the adapter cover 4 is closed, the disk 2 is received in the adapter body 1 .

The disk 2 accommodated in the adapter main body 1 is to be able to rotate when the disk 2 is loaded on a turntable (not shown) of the disk drive. Accordingly, a predetermined gap should be maintained between the disc holder 3 and the disc 2 so that the disc 2 supported by the first, second and third support sections 3a, 3b and 3c can move.

Since the disk holder 3 does not constrain the movement of the disk 2, the disk 2 may leave the disk holder 3 and fall off when the disk holder 3 is inserted into or removed from the adapter body 1, As a result, the disc 2 may be cracked or damaged. Especially when the disc 2 is moved from its intended position, ie the turntable is driven with the disc 2 in the wrong position, the information on the disc 2 may be severely damaged.

In addition, since the conventional disk adapter 5 has no structure or means for determining the size or state of the disk 2 in the disk drive, the information recording and/or playback process is occasionally prolonged.

Furthermore, common disk adapters are not used to determine whether the device in the disk drive is an adapter for holding 8cm disks or a 12cm disk cartridge, but it is very necessary for information recording and/or playback to be carried out quickly according to the type of disk. function. Accordingly, the time for recording and/or reproducing information is extended.

Detailed ways

Preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, wherein like reference numerals denote like elements.

Figure 2 shows a disk receiving adapter 8 according to the invention. Referring to FIG. 2 , the disc holder 30 includes a first support part 31 , a second support part 32 and a third support part 33 with which the positioning disc 20 is supported. Accordingly, the disc 20 is positioned on the supports 31, 32 and 33 from three points. Although FIG. 2 shows that the disc 20 is supported and positioned by the three support portions 31 , 32 and 33 of the disc holder 30 , the disc 20 may also be supported by support ribs with grooves for receiving the edge of the disc 20 . In this case, support ribs are formed along the disc support portion of the disc holder 30 .

A first elastic press section 34 and a second elastic press section 35 extend from the disc holder 30 so as to elastically press the disc 20 from opposite sides of the disc 20 toward its center. The elastic pressing parts 34 and 35 are elastically displaceable and exert an elastic biasing force on the disc 20 until an external force is applied, so that once the disc 20 is positioned on the disc holder 30, the disc 20 is held by the elastic pressing parts 34. Get up with 35 fixed supports.

At the same time, if the disc holder 30 is inserted and fixed in the adapter body 10, the disc 20 must also be able to rotate. Correspondingly, there should be a release for releasing the first elastic pressing part 34 and the second elastic pressing part 35 .

The release member is composed of a first protrusion 36 and a second protrusion 37 which are integrally formed at the ends of the first elastic pressing part 34 and the second elastic pressing part 35 respectively. The release member also includes first and second interference members 11 and 12 provided in the adapter body 10, and the first protrusion 36 and the second protrusion 37 include inclined surfaces 36a, 37a with predetermined inclination angles. The first and second interference members 11 and 12 are respectively formed into a wedge shape and a cylindrical shape, and slidably contact the inclined surfaces 36a, 37a of the first protrusion 36 and the second protrusion 37 . Here, the interference members 11 and 12 may be of the same shape, or as shown in the preferred embodiment of the present invention, the interference members 11 and 12 may be of different shapes, respectively.

In this figure, reference numeral 13 denotes a grip portion with which a user pinches the disk holder 30, and reference numerals 14a and 14b denote locking projections. Symbols and characters can be embossed on the grip portion 13 to indicate one side and the other side of the disc 20 . When the disk holder 30 is fixed in the adapter body 10 , the locking protrusions 14 a and 14 b are in tight contact with both inner side walls of the adapter body 10 .

In addition, in this figure, reference numeral 40 denotes a cover of the adapter main body 10, and when the adapter cover 40 is closed, the disk holder 30 inserted into the adapter main body 10 is firmly fixed in the adapter main body 10. More specifically, when a user rotatably closes the adapter cover 40 relative to the adapter body 10 , the lock piece 41 formed at one end of the adapter cover 40 is locked into the lock hole 42 formed on the adapter body 10 .

In the figure, reference numeral 50 denotes a shutter for selectively opening/closing a main shaft opening and an extension opening (not shown) defined on the adapter main body 10, which is slidably provided on the adapter main body 10. . Therefore, when the adapter is inserted into the disk drive, the shutter 50 is automatically opened by the disk drive's shutter opening/closing means. Accordingly, some parts of the disc 20 accommodated in the adapter body 10 are exposed, so that the disc 20 can be accessed by an optical pickup.

According to the adapter 8 constituted as above, before the disk holder 30 is fixed in the adapter main body 10, the first elastic pressing portion 34 and the second elastic pressing portion 35 of the disk holder 30 keep the disk 20 toward the disk. The center of 20 is snapped in the direction of arrow "A" in FIG. Then, as shown in FIG. 3A , when the disc holder 30 is inserted into the inside of the adapter main body 10 , the leading edges of the first and second protrusions 37 contact the first and second interference members 11 , 12 . In this state, when the disk holder 30 is further inserted into the inside of the adapter main body 10, as shown in FIG. 12, and is pressed, so that the first elastic pressing portion 34 and the second elastic pressing portion 35 of the push plate 20 are separated from each other along the direction of arrow “B” shown in FIG. 3B . Thus, the disc 20 is released from the first elastic pressing portion 34 and the second elastic pressing portion 35 and can move without being hindered by adjacent elements. Conversely, when the disc holder 30 is pulled out from the adapter main body 10, the restoring force of the first elastic pressing portion 34 and the second elastic pressing portion 35 restores it, pressing the disc 20 toward its center. Accordingly, when the disc holder 30 is pulled out of the adapter body 10, the disc 20 does not move.

As described above, since the disc 20 is automatically switched to be restricted or rotatable corresponding to the insertion or withdrawal of the disc holder 30 relative to the adapter body 10, the disc 20 will not be accidentally disengaged from the disc holder 30. open.

Meanwhile, FIG. 4 is a plan view of a disk receiving adapter 9 according to another preferred embodiment of the present invention. 5A and 5B are cross-sectional views taken along line I-I of FIG. 4, showing the structure and operation of the detection hole controller, which is the main feature of this preferred embodiment of the present invention. In addition, FIGS. 6 and 7 are cross-sectional views taken along lines II-II and III-III of FIG. 4 , respectively.

As shown in these figures, the disc receiving adapter 9 according to this preferred embodiment of the present invention has the same configuration as the adapter 8 according to the first preferred embodiment of the present invention, so this preferred embodiment according to the present invention will be omitted. A detailed description of the disc receiving adapter 9 of the first preferred embodiment, but its unique features will be described below, and the same elements are given the same reference numerals as in the first preferred embodiment.

As shown in the figure, a disc receiving adapter 9 according to another preferred embodiment of the present invention includes a box-shaped adapter main body 10, a disc holder 30, a pair of elastic pressing parts 34 and 35, first and second protrusions 36 and 37 and the first and second interference members 11 and 12.

Disc 20 is released.

The disc receiving adapter 9 according to the preferred embodiment of the present invention also includes a holder lock and a holder unlock. After the disc holder 30 is inserted into the adapter main body 10, the clamper locking part locks the disc clamper 30 at a predetermined position, and the clamper unlocking part releases the lock locked by the clamper locking part. disc holder 30 .

The holder lock includes a pair of elastic locking protrusions 14a and 14b and a pair of locking grooves 15a and 15b. The pair of elastic locking protrusions 14a and 14b are formed on opposite sides of the disc holder 30 in such a manner as to be elastically biased outward. The pair of locking grooves 15a and 15b are formed on the adapter body 10 to receive the pair of elastic locking protrusions 14a and 14b, respectively. Accordingly, when the disk holder 30 is inserted into the adapter body 10, the elastic locking protrusions 14a and 14b on opposite sides of the disk holder 30 are locked to the locking grooves formed on the respective inner side walls of the adapter body 10. 15a and 15b, and the elastic locking protrusions 14a and 14b will never disengage from the locking grooves 15a and 15b without external force.

Additionally, the holder lock includes a pair of abutment members 16 and 16' formed on opposite sides of the adapter body 10. As shown in FIG. The pressing pieces 16 and 16' have protrusions 16a, respectively, which pass through the locking grooves 15a and 15b of the adapter body 10 and come into contact with the elastic locking protrusions 14a and 14b of the disc holder 30. As shown in FIG. In this way, when the pressing pieces 16 and 16' are pressed inwardly in the lateral direction of the adapter main body 10, the protrusion 16a pushes the elastic locking protrusions 14a and 14b of the pair of disc holders 30, and as a result, the elastic locking protrusions 14a and 14b are Out of the locking grooves 15a and 15b of the adapter body 10 . Meanwhile, once the user pinches and pulls the grip portion 13 of the disc holder 30 , the disc holder 30 is disengaged from the adapter main body 10 .

In addition, according to this preferred embodiment of the present invention, an opening 10a is defined at the front side of the adapter body 10 so that the grip portion 13 is located outside the adapter body 10. As a result, it is easier to insert and pull the disc holder 30 into and out of the adapter main body 10 . Also, embossed portions are formed on the grip portion 13 to indicate the faces of the disc, and upper and lower surface indicating portions 70 are formed on one side of the adapter main body 10, and the upper and lower surface indicating portions 70 have additional embossed portions 70a and 70b, are used to indicate the upper surface and the lower surface of the adapter body 10, respectively. Thus, a user can easily identify each side, insert/pull the disk or disk holder 30 with respect to the adapter body 10 without confusion.

The disk receiving adapter according to this preferred embodiment of the present invention also includes a plurality of detection holes 51, 52, 53 and 54 formed on the adapter main body 10 at predetermined positions, once the detection switch 80 provided on the disk drive selectively By being inserted into the detection holes 51, 52, 53 and 54, the state of the disc 20 can be determined.

The A1 detection hole 51 is used to determine whether the recording surface of the disc 20 should be verified, the A2 detection hole 52 is used to determine whether the disc 20 is a single-sided disc or a double-sided disc, and the A3 detection hole 53 is used to determine whether the size of the disc 20 is 8 cm. The protection hole 54 is used to determine whether the information recording protection function has been selected.

When the A1 detection hole 51 is opened, the corresponding detection switch 80 is inserted therein, thereby determining that the disk 20 has been used at least once in the disk drive, in this case, information is recorded on the disk 20, and simultaneously Verification. On the other hand, when the A1 detection hole 51 is closed, it is determined that this disk 20 has never been used in the disk drive, so that information is recorded on the disk without verification.

In the same manner, when the A2 detection hole 52 is closed, then it is determined that the disc 20 is a single-sided disc, otherwise it is determined that the disc 20 is a double-sided disc. When the A3 detection hole 53 is opened, it is determined that the device inserted into the driver is the adapter 9 that accommodates the 8cm disc, otherwise it is determined that the device inserted into the driver is a common disc that accommodates the 12cm disc or the like.

When the write-protect hole 54 is closed, it is determined that the recording procedure can be performed, otherwise, when the write-protect hole 54 is opened, it is determined that the information write-protect function has been selected.

According to the adapter 9 of this preferred embodiment, initially, the A1 detection hole 51 and the A3 detection hole 53 are in the open state, while the A2 detection hole 52 and the write protection hole 54 are in the closed state. Therefore, when the adapter 9 is inserted into the disk drive, it is determined that the 8 cm recordable disk required for verification is inserted.

In this state, even if the disc 20 accommodated in the adapter is a new disc, or if the disc 20 accommodated in the adapter is a disc that does not need to be verified, since the A1 detection hole 51 is open, it is The trouble arises that a checkout still has to be performed within the disc drive before information recording takes place. As a result, the information recording time is prolonged.

According to this preferred embodiment, in order to avoid such trouble, the user can manually open/close the A1 detection hole 51 . In this way, when the user determines that verification is not required, he/she can block the A1 detection hole 51 to directly perform the information recording process.

In addition to the A1 detection hole 51, the A2 detection hole 52 and the A3 detection hole 53 may additionally constitute detection hole opening/closing controllers.

Referring to FIG. 5A, the A3 detection hole 53 is opened. Therefore, when the adapter 9 is inserted into the disk drive, the corresponding detection switch 80 is inserted into the A3 detection hole 53, so that the disk drive determines that the adapter 9 accommodates an 8cm disk 20.

Referring to FIG. 5B , the A3 detection hole 53 is closed by the opening/closing member 62 . Therefore, it is determined that a disc cartridge such as 12 cm is inserted instead of an 8 cm disc.

In this state, if the user wants to move the opening/closing member 62, he/she presses the opening/closing member 62 with a pointing member (a pointed member) such as a ballpoint pen, through The opening/closing member 62 is moved by the moving groove 62a on the side. Thus, the position holding projection 63 of the opening/closing member 62 is separated from the first position holding groove 64a, so that the opening/closing member 62 is moved to a desired position. Then, once the position holding projection 63 of the opening/closing member 62 is inserted into the second position holding groove 64b of the adapter main body 10, the opening/closing member 62 is fixed to the position to which it moved.

Although not shown in the figure, it is easy to understand that opening/closing the A1 detection hole 51 and the write protection hole 54 is also the same as the above method.

In addition, the above-mentioned operations and functions of the disk holder 30 (such as inserting the disk 20 into the adapter body 10 or pulling out the disk 20 from the adapter body 10) are all the same as those of the disk holder according to the first preferred embodiment of the present invention. 30, in this embodiment, the elastic pressing portion of the disc holder 30 fixes the support disc 20, or releases the disc 20 through the release member for unhindered rotation.

The following describes the method of driving the adapter 9 with the above-mentioned detection holes 51 , 52 and 53 with reference to the flowchart 100 of FIG. 8 , and specifically describes the method of driving the adapter 9 with the detection hole 53 .
