Description of the invention (/) The present invention relates to a cassette opening mechanism, and in particular to a utilization device on a tray body The swing arm and the torsion spring can easily open the cassette opening mechanism of the protective cover of the disc cassette. Among the DVD-RAM specifications released by the DVD Alliance at the end of 1997, there is a disc with a disc cartridge. This disc has a larger capacity than previous CDs, and its readable and writable functions are the future trend of the disc player market. With the considerations accepted by the entire market, it is best that future DVD-RAM drives can also read discs that have not used a disc cartridge in the past. If the optical disc drive is to be able to read and write discs with disc cartridges in the DVD-RAM specification, in the mechanism design of the optical disc drive, a cassette opening mechanism capable of opening the disc cartridge protective cover (shutter) must be added. In 1998, Hitachi (HATICHI drive model: GF-1055) and Panasonic (PANASONIC) respectively introduced DVD-RAM drives that can read disc cartridges. Please refer to FIG. 1, which shows a disc D with a disc cartridge. The disc cartridge 10 is built into the disc to protect the disc from damage by external factors. In order to be able to read the disc, Data, there is a protective cover 20 on the disc cartridge that can move and expose the disc, and there is a protrusion 30 on the protective cover 20 'When a disc with a disc cartridge is placed in the optical drive, the cartridge The opening mechanism must touch the edge of the protrusion 30 and push the protective cover 30 to expose the disc. Please refer to FIG. 2 'which shows a schematic diagram of a conventional cassette opening mechanism. In order to open the protective cover, a conventional method is to install the cassette opening mechanism 60 on a chucking plate 40. The chucking plate 40 is fixed in the optical disc drive and is located above the tray body (not shown) and does not follow. The paper size of the tray is applicable to the Chinese national standard < CMS) A < 1 蚬 (210 x 297 public love) ----------- \ ^ i ------ 丨 order --- I- ---- Line I (Please read the notes on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 46314 7 5298twf.d〇c / 〇〇6 A7 ______B7___ 5. Description of the invention (i) There is a disc laminating device and its mechanism 50 on the holding plate 40, and a cassette opening mechanism 60. The cassette opening mechanism 60 is slotted 62 'on the holding plate and one end of the swing arm 64 is fixed at On the other side of the holding plate 40, there is a swing arm restriction mechanism 66 on the other side of the holding plate 40 to restrict the swing arm 64 from making an arc-shaped movement in the groove 62, and the swing arm 64 is then combined with a telescopic spring 68 to Pull the swing arm 64 back to the original position. When the tray body is inserted into a disc with a disc cartridge, and the tray body is pushed back into the optical disc drive, the swing arm 64 will contact the edge of the protrusion on the disc cartridge protection cover, and the protection cover will be moved and exposed. The disc completes the action of opening the cassette. When the tray body is pushed out of the optical disc drive, the swing arm 64 will return to its original position due to the action of the telescopic spring. There are many defects in the design of the two cassette opening mechanisms that can open the optical disc cartridge. For example, these cassette opening mechanisms are all mounted on a chucking plate. In order to install the cassette opening, The mechanism must be slotted on the holding plate to be able to open the cassette opening mechanism. When the optical disc drive reads and writes the optical disc with the optical disc cassette, there will not be a big problem. 'When there is no disc cassette After the disc is inserted, due to the grooves in the holding plate, when the disc (bare chip) starts to rotate, 'air will form vortexes in these grooves, causing sources of vibration and noise'. This is not only the case, it may even affect the operation of the disc Speed, reducing the rotation speed of the spindle motor, thereby reducing the data transmission rate, or even causing incorrect reading and writing of data. Furthermore: Since the cassette opening mechanism has too many parts and is quite complicated, it is relatively difficult and costly in terms of time and money to slot the holding plate and install the cassette opening mechanism in the device. Therefore, the production efficiency is improved. 4 ----- I ---- ^-\ ^ -------- Order --------- line Please read the notes on the back before filling this page > Use China Shattered ticket standard (CNS) A4 specification (210 x 297 cm)-A7 B7 46314 7 52 9 8 twf doc / 0 0 6 V. Description of the invention (>). Therefore, the present invention provides a tray with a cassette opening mechanism, which can be easily completed using only a swing arm and a torsion spring, which has a simpler structure than the conventional one. The invention provides a tray with a cassette opening mechanism, which can easily open the protective cover of a disc cassette inserted into the tray body by using a swing arm, and the disc cassette is removed due to the action of a torsion spring when the disc cassette is removed. The swing arm was able to return to its original position. The invention provides a tray with a cassette opening mechanism. Since the cassette opening mechanism is mounted on the tray body, the holding plate does not need to be slotted separately for the opening mechanism, so that the conventional optical disc drive can be solved when the disc rotates. The resulting loss and wasted costs. The present invention proposes a tray with a cassette opening mechanism, which is briefly described as follows: A tray body, one side of the tray body is an inlet for placing a disc cartridge, and the other side near the corresponding side has a First shaft section. Swing arm, one end of the swing arm is a second shaft portion, which is used to be sleeved with the first shaft portion and can rotate the swing arm. When the disc cartridge is placed in the tray body, the other end of the swing arm contacts in an unopened position Go to the edge of the convex on the protective cover, push the swing arm by the disc cartridge, and finally open the protective cover when the other end of the swing arm moves to the open position. An elastic mechanism, one end of the elastic mechanism is fixed to the tray body, and the other end of the elastic mechanism is fixed to the swing arm, and the elastic mechanism exerts force to return the swing arm to the unopened position. In order to make the above objects, features, and advantages of the present invention more obvious and easy 5 ("Please read the precautions on the back before filling this page)
