Description of the invention: [Technical field of the invention] [0001] The present invention relates to an optical disk reading and writing device. [Prior Art] [0002] In view of this, it is necessary to provide a writable device. [〇 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The spindle motor on the carrier. The movement carrier is placed between the lower housing and the upper housing. The upper housing has an "opening." The spindle is over-opened and the disc is covered. The spindle motor includes a body and a wire and a carrier disk disposed in the axial direction of the body (4). The bottom plate is fixed to the movement carrier. The carrier tray is provided with a card holder for securing the optical disc. The brilliance is provided with a projection at a position opposite to the holder. [0004] A disc reading and writing device comprising a spindle motor for driving an optical disc and a disc cover opposite to the spindle motor. The β spindle motor is provided with a card holder for holding the optical disc. The disc cover is convex at a position opposite to the holder. Start. Since the disc cover is provided with a protrusion, the disc reading and writing device is in use: 'When the disc cover is deformed by pressure, the protrusion can make the other part of the disc not easily contact with the disc, and the spindle motor is rotated. 'This allows the disc reader to read and write the disc information. SUMMARY OF THE INVENTION [0006] There is a reference; +, this, it is necessary to provide an optical writing device that can improve read and write stability. 096151159 Form No. ΑΟίοι Page 3 of 15 1003269365-0 [0007] [0007] [0009] [0009] [0010] 096151159 On July 25, iOO, a disc read and write split, including a lower case, An upper casing that is fastened to the lower casing, a disc cover that is disposed on the upper casing, a movement carrier, and a spindle motor that is fixed to the movement of the movement. The remaining capacity of the machine is placed between the lower casing and the upper casing. The upper housing has an "open σ". The spindle motor is opposed to the disc cover through the opening. The spindle motor includes a body and a bottom plate and a rhyme disposed at both ends of the body. The bottom plate is fixed to the movement carrier. The carrier plate has a holder for the card. The disc cover is provided with a projection at a position opposite to the holder. The projection covers the inside of the holder. A disc reading and writing device 'includes a spindle motor that drives the optical disc and a disc cover that opposes the main shaft motor. The spindle motor is provided with a retaining seat for the optical disc. The disc cover is provided with a projection at a position opposite to the retaining seat. The raised cover is in the holder. Since the disc cover is provided with a protrusion, when the disc cover is deformed by the pressure during use, the other part of the disc cover is not easily contacted with the handle by the protrusion, and the spindle motor is rotated. Therefore, the optical disc reading and writing device can stably read and write the optical disc information. [Embodiment] Referring to FIG. 1 and FIG. 2 simultaneously, a preferred embodiment of the optical disk read/write device 200 includes a lower casing 10, an upper casing 2 可 engageable with the lower casing 1 〇, and pivoted thereon. The disc cover 30 on the side of the casing 20, the movement carrier 40, and the spindle motor 5'' disposed on the movement carrier 4'' are aligned with the optical pickup 6'. The lower body 10 is combined with the upper casing 2 to form an accommodation space for accommodating the movement carrier 40 therein. The machine carrier 40 is substantially rectangular in shape and is fixed to the lower casing 1 and located between the upper casing 20 and the lower casing 10. The center of the movement carrier 40 is open 1003269365-0 [0011] 1353596 i u is provided with a substantially rectangular closed opening 42. The optical pickup 30 is slidably mounted in the opening 42 to move radially in the pupil (not shown) and to read/record the disc information. [0012] The spindle motor 50 is fixed on the movement degree of the movement 'for carrying and driving light. The spindle motor 50 includes a substantially cylindrical body 58 ' [0014] [0015] [0016] 096151159 Rotate. The warrior plucks the eight main BJ mad body 58, and the bottom plate 52 and the carrier 54 disposed at the axial ends of the body 58. The bottom plate 52 is for fixing the spindle motor 50 to the movement carrier 4 and is opposite to the lower casing (four). The carrying tray 54 is configured to carry a compact disc (not shown), and a latching seat 56 for holding the optical disc, and the first disc is rotated and the spindle motor 50 is prevented from rotating. Separation. The upper casing 20 portion is opened downwardly from the recessed portion 22 to form a disc accommodating portion 22, and the optical disc accommodates the optical pickup head 〇 〇 〇 〇 〇 以 以 主轴 主轴 主轴 主轴 主轴 主轴 主轴 主轴 主轴 主轴 主轴 主轴 主轴 主轴For a square broadcast, and covering the optical disc accommodating zone 22, the rim-side is pivotally connected to the upper housing 2 〇 on the opposite position of the holder 56. The optical disc cover 30 has a protrusion 32 through the opening 220 and the inch. . The lower casing 10 and the spindle motor 5 are 12 pieces. The support 2 can be provided with a separate member that can also be attached to the lower casing 1 () body & on the lower casing 1G, any shape, such as a center*, which can be from the lower casing The raised support member 12 on the 10 is a ring. , the subject is the only one. In this embodiment, please refer to FIG. 3 and FIG. 4, on the group 10, the upper shell f5>n4 ", the movement carrier 40 is mounted on the lower housing body 20 and is fastened to the lower 4 (4) 1G and 'From the accommodating space formed by the combination of the squeezing core carrier 20, the form number A0101, page 5/15 pages 1353596 [100^07^, and the spindle motor 5〇 and optical reading provided on the movement carrier 40 The 60-bit upper opening 220 of the optical disk housing area 22 on the upper housing 20 is taken. The disc cover 30 is pivotally connected to the top of the optical disc accommodating area 22, and the protrusion 32 on the disc cover 30 is opposite to the retaining seat 56 through the opening 220, and the range covered by the protrusion 32 is not Exceeding the card holder 56. Preferably, the projection 32 is opposite the center position of the retaining seat 56. The support 12 of the lower casing 1 is supported on the bottom plate 52 of the spindle motor 50 and within the range covered by the body 58 of the spindle motor 5, and the center of the support 12 is positioned at the center of the bottom plate 52. The position is opposite 'that is, coaxial with the projection 32. [0017] When the optical disk reading and writing device 200 is in operation, the optical disk 70 is placed in the optical disk accommodating area 22 and fastened to the holding base 56 of the spindle motor 50. The disc cover 3 is covered on the disc valley portion 22, and the spindle motor 5 is driven to rotate the disc under the disc cover 30 in the disc housing area 22. As shown in Fig. 5, 'the downward pressure is applied to the disc cover (10), the disc cover 30 is deformed, and the projection 32 on the disc cover 3 is pressed against the spindle motor 5G from the upper side of the spindle motor 5G. The heart position, and the field member 12 on the lower casing 1G, withstands the spindle motor 50 from below the spindle motor 5(). [0018] Since the projection 32 on the disc cover 30 abuts against the center position of the holder 56, the other portion of the disc cover 30 is not easily brought into contact with the disc 7〇. Moreover, the protrusion 32 is pressed against the center of the spindle motor 5〇, and does not generate a large resistance torque to the rotation of the spindle, so that the spindle motor 5〇 does not stop rotating, so that the optical disk reading and writing device 2 can be stabilized. Read and write CD information. In addition, since the cutting member 12 on the lower cam 10 is held against the spindle motor 5G from the corresponding position below the spindle motor 5, the movement carrier 40 of the spindle motor 5Q is not deformed by the compression of the spindle motor 50. Therefore, the ergonomic reading head 60 on the core carrier 40 is tilted and is prevented from being erected on the machine 096151159 Form No. A0101 Page 6/15 pages 1003269365-0 1353596 i.
