Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a perspective view of a slot-in type optical disk drive according to an embodiment of the present invention.

As shown therein, the slot-in type optical disc drive 10 according to an embodiment of the present invention includes a main body 20, a bezel 26 on the front surface of the main body 20, and a bezel. And an optical disk insertion hole 28 provided at 26.

The main body 20 forms the appearance of the optical disk drive 10. The main body 20 forming the exterior protects each component inside from an external impact. Slot type optical disk drive 10 according to an embodiment of the present invention, the thickness of the main body 20 can be designed thinner than the tray type optical disk drive provided with components such as a tray therein. The main body 20 is formed by assembling the cover chassis 22 and the bottom chassis 24. The cover sash 22 and the bottom sash 24 may be provided by pressing a steel plate into a suitable shape, or injection molding a plastic.

The bezel 26 is provided on the front surface of the main body 20. The bezel 26 may be provided by injecting plastic separately from the main body 20, and in some cases, the bezel 26 may be integrally formed with the cover chassis 22 or the bottom chassis 24. The bezel 26 may be provided with an operation button 27 for controlling the operation of the optical disc drive 10 and an indicator light 25 indicating an operation state of the optical disc drive 10. In addition, the bezel 26 may be provided with an optical disk insertion hole 28.

The optical disk insertion hole 28 inserts the optical disk D to load the optical disk D into the main body 20, or unloads the optical disk D to which the optical disk D has been loaded. It is a passage discharged to outside. The slot-in type optical disc drive 10 according to an embodiment of the present invention is not a type in which a tray is inserted or removed. Therefore, the separate structure does not protrude out of the main body 20, the optical disk (D) can be loaded by the operation of pushing the optical disk (D) with a slight force to the optical disk insertion opening 28.

FIG. 2 is a plan view of the chassis with the cover chassis removed from the slot shown in FIG.

As shown, the optical disk drive 10 according to an embodiment of the present invention is a clamp unit 30 for generating a rotating force by chucking (loaded) the optical disk (D), and in the rotating optical disk (D) And an optical pickup unit 40 for reading or recording data, and guide arms 50 and 60 for guiding movement during the loading or unloading of the optical disc D.

The clamp unit 30 refers to an apparatus for rotating the optical disc D by the rotational force generated by the spindle motor (not shown). The clamp unit 30 is coupled to the lifting frame 32 for chucking the loaded optical disk D, the turntable 34 in contact with the clamping region D1 of the optical disk D, and the upper clamp (not shown). A clamp head 36 and an optical disk fixing portion 38 for generating a coupling force in the inner circumference of the optical disk D are included.

The lifting frame 32 is provided obliquely in a diagonal direction at the center of the optical disk drive 10 where the turntable 34 is located. When loading of the optical disc D is completed, the lifting frame 32 moves upward in the thickness direction of the optical disc drive 10. When the elevating frame 32 is moved upwards, each component of the clamp unit 30 mounted to cooperate with the elevating frame 32 may be moved upward and coupled to the upper clamp (not shown).

The turntable 34 is a portion of the clamp portion 30 that substantially contacts the clamping region D1 of the optical disk D. As shown in FIG. The clamping area D1 means the innermost side of the optical disc D, and no data is recorded in the clamping area D1. When the lifting frame 32 is raised, the tentable 34 is in contact with a corresponding region of the upper clamp (not shown), and the optical disk D is inserted therebetween. The turntable 34 may be formed of a rubber material or a soft plastic material to increase the contact force of the optical disk D.

The clamp head 36 is a convex area above the center of the turntable 34. When the lifting frame 32 is raised, the clamp head 36 is coupled to the upper clamp (not shown), so that the coupling with the upper clamp (not shown) is not released until the lifting frame 32 is lowered. In addition, the clamp head 36 is provided with an optical disk fixing portion 38 to assist the clamp head 36 and the upper clamp (not shown) and the coupling between the clamp head 36 and the optical disk (D).

The optical pickup unit 40 is a portion that reads or records data from the optical disk D that is chucked and rotated by the clamp unit 30. The optical pickup unit 40 irradiates a laser onto the surface of the optical disc D, detects the reflected laser, and reads the data, and the optical pickup 42 at a position suitable for reading or recording the data. There is provided an optical pickup transfer unit (not shown) for moving.

The guide arms 50 and 60 provide a driving force to the loaded or unloaded optical disc D, or guide the moving optical disc D to be positioned at the correct position. The guide arms 50 and 60 are provided in parallel with the optical disk insertion hole 28 and are in contact with one surface of the optical disk D to be loaded or unloaded, and have roller guides (not shown) for applying a driving force to the optical disk D. The first and second guide arms 50 and 60 guide the movement of the optical disc D on the left and right sides of the unloaded optical disc D. In the drawing of FIG. 2, the right side of the clamp unit 30 is the first guide arm 50, and the left side is the second guide arm 60.

When the optical disk D is inserted, the first guide arm 50 primarily moves along the outer circumferential surface of the loaded optical disk D in contact with the outer circumferential surface of the optical disk D. The first guide arm 50 restrains the rightward movement of the optical disc D to be inserted. This will be described in detail as follows. That is, the optical disk D is loaded into the optical disk drive 10 by the user's external force to the optical disk insertion hole (28 in FIG. 1) and the driving force by the roller guide (not shown) and the force pushing the optical disk D. . In this case, even when a force for moving the optical disc D to the right is applied, the movement is limited by the first guide arm 50. In addition, when the loading of the optical disc D proceeds for a predetermined level or more, the first guide arm 50 serves to push the optical disc D into the optical disc drive 10.

When the optical disc D is inserted, the second guide arm 60 comes into contact with the outer circumferential surface of the optical disc D second after the first guide arm 50. The second guide arm 60 guides the movement of the optical disk D in the left front side of the optical disk D to be inserted. This will be described in detail as follows. That is, when the side surface of the optical disk D inserted and loaded into the optical disk insertion hole (28 in FIG. 1) contacts the second guide arm 60 at the initial position A, the optical disk D is loaded by the moving force. The second guide arm 60 rotates in the rotational direction R about the hinge axis 62. The second guide arm 60 rotated in the rotational direction R about the hinge shaft 62 may be moved to the final position B, and the second guide arm 60 may be moved to the final position B. When the optical disk D is loaded, the loading process is finished, and the chucking process by the clamp unit 30 is performed.

The second guide arm 60 according to an embodiment of the present invention is a guide arm body 64 and a guide arm body pivoting about the hinge axis 62 from the initial position (A) to the final position (B). 64 is provided at the end of the optical disk (D) in contact with the side of the optical disk (D) and rotates in the vertical direction with respect to the roller portion 70 and the roller portion 70 to maintain the rotated state downward It includes an elastic body (80 of FIG. 3) to give, and a guide link 90 for applying a rotational force so that the roller portion 70 is rotated upward in conjunction with the position of the second guide arm (60).

The guide arm body 64 is provided with a hinge shaft 62 on one side so as to rotate in the rotational direction R in the optical disk drive 10. The rotation range of the guide arm body 64 is an area between the initial position A in which the optical disk D is unloaded and the final position B in which the optical disk D is loaded. The guide arm body 64 that rotates between the initial position A and the final position B includes a roller portion 70 provided at the opposite end of the hinge shaft 62.

The roller portion 70 is provided at the end of the guide arm body 64. The roller unit 70 contacts the side surface of the optical disc D in the process of loading or unloading the optical disc D. The optical disk drive 10 according to the embodiment of the present invention is provided such that the roller unit 70 can rotate in the vertical direction with respect to the plane of the optical disk D. That is, when the optical disk (D) is first contacted, the roller portion (70) is rotated downward. In the process of loading the optical disk (D), the roller portion (70) rotates in the opposite direction to the rotated direction and returns to its original position. do. As the roller portion 70 rotates or returns to its original position according to the progress of loading or unloading, it is possible to prevent loading and unloading errors that may occur due to the optical disc D coming off the roller portion 70. In the process of rotating the guide arm body 64, the roller part 70 may prevent an error that may occur due to interference with other structures inside the optical disk drive 10. The elastic body (80 of FIG. 3) and the guide link 90 are involved in the process of rotating the roller 70. The detailed configuration of the roller unit 70 and the operation of the roller unit 70 by the elastic body 80 of FIG. 3 and the guide link 90 will be described in more detail below.

FIG. 3 and FIG. 4 are views illustrating respective states of the type optical disc drive roller part of FIG.

In these drawings, in order to clearly explain the configuration and operation of the roller unit 70 and the elastic body 80, the specific illustration of the other components, including the guide link 90 is omitted.

FIG. 3 shows the roller part 70 in the case where the guide arm 60 is located at the initial position (A of FIG. 2). As shown in the figure, the elastic body 80 imparts elastic force to the roller portion 70 at one side of the roller portion 70. Specifically, the elastic body 80 may be a compression spring or a leaf spring that resists the compressive force, and in the drawings is shown for the case of a compression spring. The elastic body 80 applies an elastic force to the roller portion 70 upwards. When the elastic body 80 applies an elastic force upward from one side of the roller portion 70, the roller portion 70 rotates in the clockwise direction CW around the hinge portion 72. That is, the roller portion 70 is kept inclined downward by the other side by the elastic force of the elastic body 80 unless a separate external force is applied.

4 shows the state of the roller portion 70 when the guide arm 60 is located at the final position (B of FIG. 2). As shown in the drawing, the roller portion 70 may rotate in the counterclockwise direction (CCW) around the hinge portion 72 by an external force. The external force is a force that can overcome the elastic force by the elastic body (80). External force is transmitted by the guide link (90). The detailed operation of the guide link 90 will be described below. However, if a force equal to or greater than the elastic force of the elastic body 80 facing upward is applied downward by the guide link 90, the roller portion 70 is counterclockwise (CCW). It is obvious that it can be rotated by).

5 and 6 are views showing respective states of the type optical disk drive guide arm which is the slot shown in FIG.

These figures show the shapes of the guide arm 60 viewed from the side of the optical disk drive (10 in FIG. 2) in the initial position (A in FIG. 2) and the final position (B in FIG. 2), respectively. In these figures, unlike FIG. 3 and FIG. 4, the structure of the guide arm 60 and the guide link 90 was shown in more detail.

FIG. 5 shows the roller part 70 in the case where the guide arm 60 is located at the initial position (A of FIG. 2). If the self-weight of the guide link 90 itself is ignored, the external force acting by the guide link 90 at the initial position (A of FIG. 2) may be regarded as zero. The guide link 90 has a first end 92 in contact with the roller 70 and a second end selectively in contact with the convex portion 29 or the recess 23 of the guide plate 21. And a body portion 96 connecting the first end 92 and the second end 94. As shown, in the initial position (A of FIG. 2), the second end 94 is located at the recess 23 rather than the convex portion 29 of the guide plate 21. Therefore, no additional force is applied to the second end 94. The first end 92 and the second end 94 are bent in opposite directions with respect to the body portion 96, and the body portion 96 is rotatably guided by the U-shaped guide 74. ) Is combined. On the other hand, the first end 92 is coupled to the roller portion 70. Since the roller portion 70 is one side is moved upward by the elastic body 80, the first end 92 is naturally inclined upward, the second end 94 is naturally inclined downward. Therefore, the roller unit 70 maintains the inclined state in a state where no separate force is applied to the second end 94 side.

FIG. 6 shows the roller part 70 in the case where the guide arm 60 is positioned at the final position (B of FIG. 2). Referring to FIG. 2, when the guide arm 60 is in the initial position A, the second end 94 of the guide link 90 is a main portion of the guide plate 21 having a flat shape (23 in FIG. 5). ) Therefore, as described above, the second end 94 becomes a free end and does not receive a separate external force. However, when the second end 94 is out of the recess (23 in FIG. 5) in the process of moving the guide arm 60 in the rotational direction (R in FIG. 2), the convex portion 29 on the plane of the guide plate 21 is applied. You will come across. However, since the recessed part 23 and the convex part 29 are merely names according to their relative depths, the convex part 29 does not necessarily have to be convex, and it is sufficient if the concave part 23 has a higher structure than the concave part 23. That is, in the optical disk drive 10 according to the embodiment of the present invention, the recess 23 is a groove formed in the guide plate 21, and the convex portion 29 is the guide plate 21 plane itself. In the process of moving the guide arm 60 from the initial position (A in FIG. 2) to the final position (B in FIG. 2), the second end 94 comes into contact with the convex portion 29 of the guide plate 21. . When the second end 94 contacts the convex portion 29, the guide link 90 rotates in the link rotation direction L which is counterclockwise by an external force. That is, when the second end moves upward in contact with the convex portion 29, the body portion 96 rotates in the link rotation direction L that is counterclockwise, and as a result, the first end 92 moves downward. do. Thus, the roller portion 70 rotates to reach a position substantially parallel to the optical disk plane.

7 to 9 are diagrams illustrating an operation process of the type optical disk drive of FIG. 1.

As shown in FIG. 7, when the optical disc D is pushed into the optical disc drive 10 in the insertion direction I, the optical disc D is sequentially in contact with the first and second guide arms 50 and 60. . At this time, the optical disk (D) is in contact with the upper surface of the roller portion 70 of the second guide arm 60 and the loading is made naturally.

8 shows a contact process between the roller unit 70 and the optical disk D. As shown in FIG. As described above, the optical disk (D) is smoothly loaded only when the optical disk (D) is in contact with the upper surface of the roller portion 70 of the second guide arm (60). The roller unit 70 according to the exemplary embodiment of the present invention is in contact with the optical disc D while being rotated in a clockwise direction CW around the hinge portion 72. Therefore, the optical disc accommodating range capable of accommodating the optical disc D without a loading error can be significantly increased from the conventional G1 to G2 in which the roller portion 70 is fixed without rotation. That is, when the optical disk (D) is loaded to the position as shown in Figure 8, in the conventional case is out of the range of G1, the optical disk (D) can be entered under the roller portion 70. . Therefore, the normal optical disc D cannot be loaded. However, in the case of the present invention, since the roller unit 70 is rotatable downwardly and the acceptable range is increased from G1 to G2, even in such a case, the normal optical disc D can be loaded.

9 shows a state where the loading of the optical disc D is completed. As shown in the drawing, when loading of the optical disc D is completed, the first and second guide arms 50 and 60 are released from the optical disc D. FIG. On the other hand, the guide link 90 is completely out of the recess 23 of the guide plate 21. When the guide link 90 is out of the recess 23, as shown in Figure 6, the roller 70 is maintained in a parallel state as in the usual case. Therefore, it does not interfere with other components of the optical disc drive 10.

In the above-described embodiment, the case in which the elastic body is a compression spring has been mainly described, but the type of the elastic body is not limited thereto. Of course, springs and the like are possible.

As described above, the present invention is not limited to the described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
