As shown in FIG. 2 and FIG. 3A, the guide member 234 is connected to the back of the body 233, and it can move relatively to the body 233. The panel further includes a first lateral through hole 236 and a sliding button 237. The first lateral through hole 236 is formed at the body 233 in the mode of paralleling the movement direction of the guide member 234, and it is adjacent to the guide member 234. The sliding button 237 is disposed at the front end of the body 233, and the back of the sliding button 237 has a fixing member 237a. The fixing member 237a passes through the first lateral through hole 236 to be combined with the guide member 234. The lateral size of the fixing member 237a is smaller than the lateral size of the first lateral through hole 236. Then the sliding button 237 can drive the guide member 234 to laterally move.
In a preferred embodiment, the guide member 234 has a through hole corresponding to the first lateral through hole 236, and the fixing member 237a of the sliding button 237 can be fastened to the through hole. The front surface of the body 233 may have a recessed runner 2361. The recessed runner 2361 is adjacent to the edge of the first lateral through hole 236, and the lateral size of the recessed runner 2361 is larger than the lateral size of the first lateral through hole 236. In this way, the sliding button 237 can laterally slide in the recessed runner 2361.
As shown in FIG. 3A, the panel further includes two first lateral retaining walls 2331 which parallel the movement direction of the guide member 234. The first lateral retaining walls 2331 are formed at the surface of the body 233, and they are adjacent to top and bottom sides of the guide member 234, respectively.

In the embodiment, the first side edge 2334 is located at the top edge of the body 233, and the first guide channel 2341 is an oblique long channel. The first guide channel 2341 extends from the first end 2341a at the top-left to the second end 2341b at the bottom-right (seen from the back of the panel).
In FIG. 2, the first fastening member 2351 has a sheet structure and a first guide pillar 2351a protruding from the sheet structure. The first fastening member 2351 is disposed between the body 233 and the guide member 234, and the first guide pillar 2351a is inserted into the first guide channel 2341.
As shown in FIG. 3A, in the embodiment, the panel further includes two longitudinal retaining walls 2332 perpendicular to the movement direction of the guide member 234. The longitudinal retaining walls 2332 are formed at the surface of the body 233, and they are adjacent to right and left sides of the first fastening member 2351, respectively. Then, the longitudinal retaining walls 2332 can limit the position of the first fastening member 2351 in a left-right direction to limit the first fastening member 2351 to longitudinal movement.
In FIG. 3A, when the panel is in a unlocked state, the first fastening member 2351 is within the first side edge 2334 of the body 233. The first guide pillar 2351a is located at the bottom-right of the first guide channel 2341. In a preferred embodiment, the first guide pillar 2351a is located at the second end 2341b of the first guide channel 2341.
FIG. 3B is a schematic diagram showing a panel of an embodiment of the invention in a locked state.

At that moment, the guide member 234 cannot be easily moved toward the right. A user should apply certain external force to push the sliding button 237 to make the two elastic arms 2343 and 2344 deformed, and then the guide member 234 can be moved toward the right.
As shown in FIG. 3B, when the panel is in the locked state, the guide member 234 is moved to the right, and the two protrusions 2343a and 2344a are located at the right of the second lateral retaining walls 2333. At that moment, the guide member 234 cannot be easily moved toward the left. A user should apply certain external force to push the sliding button 237 to make the two elastic arms 2343 and 2344 deformed, and then the guide member 234 can be moved toward the left.
In the embodiment, the guide member 234 further has a second lateral through hole 2346. A locking member 2347 has a locking end 2347b and an expansion end 2347a. The locking end 2347b passes through the second lateral through hole 2346 to be fixedly connected to the body 233. The longitudinal size of the expansion end 2347a is larger than the longitudinal size of the second lateral through hole 2346 to limit the front-back movement of the guide member 234.
The front and back of the guide member 234 are adjacent to the back of the panel and the expansion end 2347a of the locking member 2347, respectively. In a preferred embodiment, the locking member 2347 is a screw. Furthermore, the locking end 2347b of the screw also can be used to limit the length of the lateral movement distance of the guide member 234.
In the embodiment, the first fastening member 2351 which can protrude from the first side edge 2334 of the body 233 is used to be upward fastened to the base (the third member) of the notebook computer. In another preferred embodiment, a second fastening member which can protrude from a second side edge 2336 of the body 233 may be added. The second fastening member may be downward fastened to the base (the fourth member) of the notebook computer further to allow the panel to be steadily locked. As shown in FIG. 4A and FIG. 4B, they are schematic diagrams showing the panel in an unlocked state and a locked state, respectively.
As shown in FIG. 4A, the body 233 further has a second side edge 2336. The guide member 234 further has a second guide channel 2342 having a third end 2342a and a fourth end 2342b. The third end 2342a is nearer to the second side edge 2336 than the fourth end 2342b. In a preferred embodiment, the second side edge 2336 is located at the bottom edge of the body 233, and the second guide channel 2342 is an oblique long channel. The second guide channel 2342 extends from the third end 2342a at the bottom-left to the fourth end 2342b at the top-right.
The panel further includes a second fastening member 2352 disposed between the body 233 and the guide member 234. The second fastening member 2352 also has a sheet structure and a second guide pillar 2352a protruding from the sheet structure, and the second guide pillar 2352a is inserted into the second guide channel 2342.
As shown in FIG. 4A, when the panel is in the unlocked state, the second fastening member 2352 is within the second side edge 2336 of the body 233, and the second guide pillar 2352a is located at the top-right of the second guide channel 2342. In a preferred embodiment, the second guide pillar 2352a is located at the fourth end 2342b of the second guide channel 2342.
As shown in FIG. 4B, it is a schematic diagram showing the panel of the embodiment of the invention in a locked state. When the guide member 234 is driven by the sliding button 237 to move toward the right, the second guide pillar 2352a moves from the fourth end 2342b to the third end 2342a along the second guide channel 2342. In this way, the sheet structure of the second fastening member 2352 is driven to protrude from the second side edge 2336 of the body 233 to be downward fastened to the base of the notebook computer. Therefore, when the panel is in the locked state, the second fastening member 2352 is downward fastened to the base (the fourth member) of the notebook computer to prevent the tray from sliding out.
In the embodiment, when the guide member 234 is driven by the sliding button 237 to move toward the right, the first fastening member 2351 upward protrudes from the top edge (the first side edge 2334) of the body 233, and the second fastening member 2352 also downward protrudes from the bottom edge (the second side edge 2336) of the body 233. In this way, the panel is locked further steadily, and the tray cannot easily slide out.
In the above embodiment, the movement direction of the guide member and the extension directions of the first and second guide channels can be changed according to an actual requirement. For example, if the guide member is moved toward the left to allow the panel to be locked, the first guide channel is changed to extend from the first end at the bottom-left to the second end at the top-right. When the panel needs to be locked, the guide member should be moved toward the left. At that moment, the first guide pillar moves from the first end at the bottom-left to the second end at the top-right, and then the first fastening member upward protrudes from the top edge of the body of the panel. Therefore, the above changes can be easily obtained based on the concept of the invention, and they are within the scope of the claims of the invention.
FIG. 5 is a schematic diagram showing a notebook computer of an embodiment of the invention. The notebook computer 20 at least includes a base 21 and a screen 22. The optical disk drive is disposed in the base 21 of the notebook computer 20, and it at least includes a body 231, a tray (not shown) and a panel. The panel is disposed at the front end of the tray. When the optical disk drive is not used, the sliding button 237 can be slid toward the left to allow the first fastening member 2351 to upward protrude from the top edge of the body 233 of the panel. Then, the first fastening member 2351 is fastened to the base (the third member) of the notebook computer.
To sum up, via the design of the panel mechanism of the invention, when the optical disk drive is not used, it can be locked to prevent the tray from sliding out; when the optical disk drive needs to be used, it can be unlocked to allow the tray to smoothly slide out.
Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope of the invention.
