The cover 6 3 is opened (downward) on the outside. -A large-area second release port 7 7 is formed in the rear end portion of the inlet channel 75 (on the side of the rear plate 61), and is opened (downward) to the outside of the lower cover 63. A dust collecting filter is detachably provided on the inside of the inlet port 7 4 of the front plate 60 and the middle of the inlet passage 75. Furthermore, when the optical disc device 5 is shipped from the factory, a seal is provided inside the emergency hole 6 9 so that the sealing hole 6 9 communicates with the inside of the optical disc device 5 as shown in FIG. 16. In an emergency situation, when the disc is ejected, the computer user can easily penetrate the seal 7 9 ′ by inserting a rod-shaped member into the emergency hole 6 9, and then manually release it by turning the cam lever 3 4 A disc 2 is in the direction of the arrow e, as shown in FIG. 3. Preferably, as shown in FIGS. 15 and 20, the joint 80 between the printed board 6 4 and 65 and the cutout or hole 8 1 in the upper cover 6 2 is sealed with a seal 8 2, 8 3 . Therefore, when the optical disc device 5 is installed on the inside of the front plate 1 1 1 a of the computer body 1 1 1 of the computer device 1 10, as shown in FIG. 13, most of the inlet ports 7 4 are outside the front plate 1 1 1 a By this opening, the first and second release ports 76, 77 are opened to the inside of the computer body 1 1 1. When the disc 1 is recorded and / or reproduced by the disc device 5 (as shown in FIG. 15, the disc inlet / outlet 4 is loaded by the disc front plate 2B of the disc 2 in the disc device body 6 during the recording and / or reproduction operation.

Description of the invention (20) The inlet channel 75 and the first and second releases 璋 7, 6, 7 7 are drawn into the computer body 1 1 1 in the forward direction, as shown by the arrow in Figure 15 The β shown is a note on the back of the book, and then fill in this page) In other words, 'the majority of the inlet ports 7 4 have an opening area set to be larger than the narrowness between the inner periphery of the disk inlet / outlet 4 and the disk front plate 2 Β Gap and all the narrow gaps left in the attachment holes of the pop-up button 6 8, the headphone jack 70, the attachment holes of the volume control 71 Orofacial Zhen, as shown in FIG. In addition, the emergency holes 69 inside the holes are sealed. This arrangement uses a bleed air to be drawn in in a forward direction from most of the inlet ports 74 through the inlet channels 75 and the first and second release ports 76, __7 7 as shown by the arrows in FIG. 15. Therefore, the air pressure in the inlet passage 75 becomes higher than the air pressure in the disc loading space 84 defined in the disc device body 6 between the upper cover 62 and the printing plates 64, 65. Therefore, it can significantly prevent open air from passing through the narrow gap between the inner periphery of the disk inlet / outlet 4 and the disk front plate 2B and the attachment hole left in the eject button 68, the headphone jack 70, and the volume Control the narrow gap in the attachment hole of 71 and suck it into the disc loading space 84 in the disc device body 6 "4'-in the free department, and DT eliminates the cooperation 结果 As a result, it can be as much as possible The dust in the open air is prevented from being sucked into the dish loading space 84 of the dish device body 6 together with the open air. Therefore, the sucked dust can be prevented from sticking to the recording and / or reproducing surface of the optical disc 1, or sticking or depositing on the disc table 40 and the objective lens 4 2 of the optical pickup 41, and preventing the laser beam from being irradiated to the optical disc 1.

Achieving high-performance and high-quality optical disc devices

J In addition, by setting the opening area of the first release port 7 6 in the entrance channel 75 as large as possible, and making the position of the first release lever 76 as close to the entrance port 7 4 as possible, via the entrance port 7 The dust sucked into the inlet passage 7 5 can be quickly released to the outer boundary of the dish device body 6, and thus can prevent further entry into the inlet passage 7 5, and then enter the dish loading space 8 4 from the middle of the inlet passage 75. Furthermore, the emergency hole 6 9 closed by the sealing member 7 9 can prevent dust from being sucked into the dish loading space 8 4 through the emergency hole 6 9. Furthermore, the joint 80 between the printed board 6 4, 6 5 and the notch or hole 81 in the upper cover 6 2 closed by the sealing members 8 2, 8 3 and the air in the inlet passage 7 5 The pressure can be maintained even higher than the air pressure in the disc loading space 84. As a result, the dustproof effect of the optical disc device 5 can be further improved. Furthermore, as shown in FIG. 15, most of the electronic circuit components 6 6 are mounted on the lower surface of the printed board 6 4 * 6 5 and are between the lower surface of the printed board 6 4 and 6 5 and the lower cover 63. The gap is used as part of the inlet channel 75. This arrangement has another advantage, since most electronic circuit elements 66 are air-cooled by a sufficient amount of open air flowing through the inlet channel 75, so that an electronic circuit element such as an IC can be prevented from being caused by an excessive temperature rise 6 6 failure.

Furthermore, the L-shaped mating ears 8 8 are integrally formed on the left and right ends of the vertical rear surface 2 b of the front plate 2 B, so as to extend vertically downward first * and then bend at right angles to form the mating ears 8 9 to each other. The center of the upper part of the rear surface 2 b projects vertically downward, and is integrated with a pair of left and right mating protrusions \ 90 to form the lower part of the rear surface 2 b at positions near the left and right ends. The mating ears 85, 86, the mating recesses 87, the L-shaped mating ears 8 8, the mating ears 8 9, and the mating protrusions 90 form a mating joint between the disc body 2 A and the disc front plate 2 B. On the rear surface 2 b of the front plate 2 B, a horizontal rib 9 1 is integrated to horizontally interconnect the pair of left and right L-shaped fitting ears 8 8 and the fitting ears in the central part above the rear surface 2 b.

Description of the Invention (24) The central part of the ear 86 and the pair of left and right mating convex portions 90 are fitted respectively to fit the pair of left and right mating concave portions 87. With such a matching condition, the disk front plate 2 B can be arranged in any three-dimensional direction, that is, 'vertical, horizontal' or vertical. Regarding the above installation steps, first, the left and right ends of the disk front plate 2 B are warped by the central part in the direction of arrow a /, as shown by the dotted line in FIG. The connector is assembled to the front surface 2 a of the disk body 2 A, and is fixed to the direction of arrow a at the left and right ends, against the elasticity of the disk front plate 2 B. Thereby, in the fully assembled state, the plate body 2 A and the plate front plate 2 B are in pressure contact with each other between all four vertical ribs 92 and the pair of left and right L-shaped fitting ears 8 and 8, while on the plate front plate On the left and right ends 2 of 2 B, the elastic reaction force in the direction of arrow a # develops, and they are forced in the opposite directions of arrows a and a ~. As a result, the disc front plate 2B can be assembled to the disc body 2 A without a gap, and a disc disc 2 with high quality can be achieved. However, in the disc 2 described above, since three cutouts 94 are formed in the rear surface of the disc front plate 2 B to perform the undercut operation, as described above, the disc formed in the front plate 60 of the disc device body 6 The outlet 4 cannot be easily sealed by the disc front plate 2 B. In order to eliminate this disadvantage, in the optical disc device 5 of this embodiment, the endless annular elastic member 9 5 having a circular cross section is formed of rubber or a soft synthetic resin, and is assembled on the rear surface of the disc front plate 2 B, and The recesses defined by the peripheral ribs 9 3 form a fitting relationship. Therefore, the annular elastic member 9 5 surrounds the pair of left and right L-shaped fitting ears 8 8, the horizontal ribs 9 1, and the three notches 9 4 ′ as shown in FIGS. 15, 16 and As shown in Fig. 18, under this condition, the ring-shaped elastic member 9 5 is assembled in the state where the member 9 5 is subjected to the initial tension = Chinese paper standard (CNS) A4 specification (210X297 mm) L --- ----------.--- © ------.- IT ------ ο— (Please read the precautions on the back before filling in the JS page). -27- 409239 a? ____B7 V. Description of the invention (25) {Please read the notes on the back before filling in the form page) As shown in Figures 15 and 16, when the disc 2 is fully loaded into the disc device body 6 in the direction of the arrow az During the middle period, the annular elastic member 95 is forced into close contact with the inner peripheral surface of the disk inlet / outlet 4 to resist elasticity, and at the same time, the lower edge portion of the annular elastic member 95 is forced to three positions. Against the elastic notches 94 into three. Therefore, the disc inlet / outlet 4 and the three gaps can be reliably sealed. Since the cross-section of the ring-shaped elastic member 95 is circular * The ring-shaped elastic member 95 can be easily under friction caused by pressure contact between the outer peripheral edge of the ring-shaped elastic member 95 and the inner peripheral surface of the disk inlet / outlet 4 Around the center of the circular section. Therefore, it can be ensured that the outer peripheral edge of the annular elastic member 95 can be smoothly and reliably formed in pressure contact with the inner peripheral surface of the disk inlet / outlet 4, and therefore, the disk inlet / outlet 4 can be reliably sealed, as shown in FIG. As shown at 6 and 6, a large load is formed on the loading motor 28 for the disc 2. '' As the disc inlet / outlet 4 can be sealed with the disc 2 fully loaded in the disc device body 6, dust can be prevented from entering the disc device body 6 through the disc inlet / outlet 4, and an optical disc device can be provided 5Higher dustproof effect. Furthermore, since it is endless *, the ring-shaped member 95 can be easily attached and detached from the disc 2 by appropriately stretching the ring-shaped elastic member 95 to resist elasticity. The assembly and replacement of the ring-shaped elastic member 95 can also be easily performed. In addition, part of the cost of the ring-shaped elastic member 95 is also quite low. [Description of Disc Clamp Mechanism] The disc clamp mechanism will be described with reference to Figs. The paper formed by the circular plate is generally in accordance with China's national standard (0 ^) 8-4 specifications (2〗 0 > < 297 mm) -28-A7 ____B7_ V. Description of the invention (26) Disc clamps 5 3 for synthesis Resin is formed, and is formed as a non-magnetic member * and a flange 5 3 a integrated with the outer periphery of the disc clamp 53. The circular recess 5 3 b opened downward and the central pin protruding downward from the center of the circular recess 5 3 b are formed in a raised position in the center position of the disc clamp 53. The ring magnet 97 and the yoke 98 are inserted into the circular recess 53b by insert molding, for example, and surround the center pin 53c. The yoke 9 8 is horizontally disposed in a vertically stacked state. The yoke 9 8 is horizontally disposed on the upper surface of the magnet 97. The magnet 97 is magnetized in the vertical direction (that is, in the axial direction of the center pin 5 3 c), and therefore, the magnetic attraction of the magnet 97 acts in the vertical direction. The cover 62 formed of a metal plate is regarded as a magnetic member and is horizontally arranged on the clamp support member 5 2. The clamp support member 5 2 is formed of a metal plate and has a clamp receiver 5 2 a for moving from below. Supports the flange 5 3 a of the disc clamp 5 3. Therefore, the upper cover 62, which is regarded as a magnetic member, is arranged horizontally above the disc clamper 53. The disc table 40 and the concentrated guide 40 a provided on the central portion of the disc table 40 are formed of metal and serve as magnetic members. A central reference hole 40b is formed in the center of the concentrated guide 40a.

In the reprinted condition shown in Figure 22, since the magnetic stage 40 is lowered to the lowered position in the direction of the arrow c > The vertical magnetic attraction generated by the magnet 9 7 in 5 3 acts between the disc clamper 5 3 and the upper cover 6 2, so that the disc clamper 5 3 is upward from the clamp position shown in FIG. 2 in the direction of the arrow b. Move to the raised position. Therefore, the disc clamp 5 3 is magnetically attracted to the lower surface of the upper cover 6 2. In this structure, because the yoke 98 is horizontally disposed on the surface of the magnet 97, the Chinese paper standard (CNS) A4 specification (210X297 mm) -29- Μ 浐 部 呔 is used for the paper size of the magnet. ir ^ -AhJ · Consumption cooperation phase print ii 409239A7 ______B7____ V. Description of the invention (27) The magnetic attraction force acting upwards from the 7 7 is smaller than the magnetic attraction force acting downwards from the magnet 9 7. Furthermore, since the disc clamp 5 3 is kept adjacent to the lower surface of the upper cover 62 through the central wall above the circular recess 5 3 b, the magnet 9 7 is caused by the appearance of the central wall above the circular recess 5 3 b. The magnetic attraction force acting upward is weaker; therefore, under relatively weak magnetic attraction force, the disc clamp 5 3 is attracted to the lower surface of the upper cover 62. Move upward in the direction of the arrow b of the disc clamp 5 3 to a raised position that is adjacent to the lower surface of the upper cover 62 2, between the lower surface of the clamp support member 5 2 and the lower surface of the disc clamp 5 3. The gap L 3 is smaller than the amount of the gap L 1 shown in FIG. 7 by the amount of L 4 that the disc clamper 5 3 raised on the clamp support member 52. Therefore, the gap L 5 between the lower surface of the disc clamper 5 3 and the upper surface of the optical disc 1 carried in the horizontal condition of the disc 2 is set to a minimum to ensure that there is no interference during the release condition. In this case, the entire gap L 3 + L 5 between the lower surface of the clamp support member 5 2 and the upper surface of the optical disc 1 can also be formed smaller than the lower surface of the clamp support member 5 2 and shown in FIG. 7. The entire gap L 1 + L 2 between the upper surfaces of the optical disc 1 is determined by the rising amount L4 of the disc clamper 53. In other words, the relationship of (L3 + L5) < (L1 + L2) originates from L3 + L5 + L4 = L1 + L2. As a result, the overall thickness of the optical disc device can be reduced.
