Description of the Invention: [Technical Field of the Invention] The present invention relates to a optical disk reading and writing device. [Prior Art] There is a need to provide a disc reading and writing device which can improve the stability of reading and writing. a disc reading and writing device that includes a lower casing, an upper casing engageable with the lower casing, a disc cover that is disposed on the upper casing, a movement carrier, and a crucible fixed to the movement carrier The spindle motor on. The movement carrier is placed between the lower = and upper housing. The upper housing has an opening. The spindle motor is opposed by opening the ends of the cover. The spindle motor includes a body and is disposed in the body axial direction 3 = and the carrier disk. The bottom plate is fixed to the movement carrier. Carrier disk; and = card holder. A disc reading and writing device is disposed at a position opposite to the card holder, and the card includes a disc motor, a spindle motor and a cymbal of the cymbal, and a card with a card. A protrusion is provided at a position where the disc cover and the card are held in pairs. Since the disc cover is provided with a convex saucer, the disc cover is subjected to pressure and the first disc is placed on the other part of the disc cover, and the light can be made through the projection: = Easy to contact with the optical disc, to maintain the spindle motor rotation, r dual device to stabilize the reading and writing of optical disc information. [Summary of the Invention] It is necessary to have a reading and writing device. ^ For a disc that can improve the stability of reading and writing 6 200929187 . A disc reading and writing device, 1 pack of the upper casing of the lower jaw, the cover is attached to the upper casing 2 and the lower casing buckles • Bao Wei — π# The first disc of the body, the movement carrier and the solid..

The spindle motor passes through the opening and == the spindle motor includes a body and the bottom plate disposed at both ends of the body is fixed to the movement carrier. The carrier tray is provided with a holder for 2 solid discs. The handle cover is provided with a protrusion at a position opposite to the cutting seat. A gentleman's disc reading and writing device' includes a spindle motor that drives the optical disk and a disk cover that faces the spindle motor. Spindle 〃 ★ Shenma violates s and has a card holder for the card, and the position of the disc 盍 and the card holder (4) is free of protrusions. to! The cover is provided with a protrusion, and the disc reading and writing device can make the other parts of the disc cover not easily contact with the optical disc when the p-disk using the disc cover is deformed by the pressure, and the special bee motor rotates. Therefore, the optical disc reading and writing device can stably read and write the optical disc information. [Embodiment] FIG. 1 and FIG. 2 'A preferred embodiment of the optical disc read and write includes a lower casing 1 , an upper casing 20 engageable with the lower casing 10 , and a lower casing The disc cover 30 on one side, the movement carrier 4〇, and the spindle motor 5G on the movement carrier 40 and the optical pickup 6〇. The lower housing 1G and the upper housing 2G are combined to form an accommodation space for receiving the core carrier 40 therein. The movement carrier 40 is substantially rectangular in shape and is fixed to the lower casing ι and located between the upper casing 2G and the lower casing 1G. The center of the machine & mount 4 200929187 has a substantially rectangular slidably erected in the opening 42 and moves and takes 5 discs to record the information on the disc. The opening 42. The optical pickup 3 can be transported radially on a disc (not shown), and the shaft motor 5 is clamped to the movement carrier 40 for carrying and driving the rotation of the disc. The spindle motor 50 includes a substantially cylindrical body 58' and a bottom plate and carrier plate 54 disposed at axial ends of the body 58. The δ hai floor 52 is used to fix the spindle motor 5 to the movement carrier and is opposite to the lower body 1 。. The carrier 54 is used to carry a disc (not shown) and has a holder 56 for holding a disc (not shown) at its top to prevent the 5 disc from being separated from the spindle motor when rotated. The upper casing 20 is partially recessed downwardly to form a disc accommodating area 22, and an irregular opening 22Q is opened in the optical disk accommodating area U for the spindle motor to rotate and the optical pickup 60 to move. The optical disc ^30 is a square structure, and its trailing edge-side is pivotally connected to the upper casing 220 to cover the disc receiving area 22. The disc cover 3 is provided with a projection 32 at a position opposite to the opening/card holder 56. The branch 10 is provided at a position opposite to the bottom plate 52 of the spindle motor 50. The cutting member 12 can be 111 separately and can be integrally formed with the lower casing 10, and can be any shape protruding from the lower casing 1 such as a cylindrical body. a ring. * In the present embodiment, 凊 referring to FIG. 3 and FIG. 4, after assembly, the upper housing 2G of the movement carrier housing is fastened to the lower housing and placed on the lower housing 10 and the upper housing 20 Combined with the formed 8 200929187 volume space 'and set on the movement carrier 4 li Li light =: upper: body 1. The protrusion 32 on the optical disk 盍 30 above the optical disk capacity L passes through the opening 22 〇 opposite 'and the convex 32 covers the range not exceeding the holding seat; 6 is outside: the ground, the convex 32 and the holding The position of t ^ ± ^ 0 of the seat 56 is opposite. The lower casing 10 j is supported by the member 12 within the range covered by the body 58 of the bottom motor 5〇 of the spindle motor 5〇' and the branch; the position of the 相对^ is opposite to the center position of the bottom plate 52, that is, the bulge 32 coaxial optical disc reading and writing device 2 〇 () when working, "7 (^ 22 and is stuck on the spindle holder 5 of the spindle motor 56. The iris cover is placed on the optical disc accommodating area 22, the spindle motor 5 () In the cover 30 cover to drive the disc to rotate under the disc cover 30. If the disc 'set 22 inner lid 30 applies a downward pressure, the light does not, at this time on the disc a slave spindle motor 5 =: 抿 = ~ 10,000 Resist the spindle horse far $ 〇 ❹ 6 = 6 zhong zhong ' and the cutting piece on the lower casing 1Q 〗 〖 5 〇 under the spindle motor 5 〇. The king shaft motor due to the protrusion 32 on the disc cover 30 The live card is held on the 'the other part of the disc cover 3〇 is not easily in contact with the optical disc 70. : The projection 32 is against the spindle motor 5 ^. The rotation of the 'shaft produces a large resistance torque, so that the spindle motor moves 5〇, the first disk read/write device 200 can stably read and write the information of the optical disk. In addition, due to the support of the lower casing 1 - spindle motor II I: 9 200929187 Positioning against the spindle motor 5, the carrier 40 is not deformed by the spindle 焉 so that the machine wrath of the spindle motor 50 is fixed in the movement carrier.
