Description
- This application is a continuation of application Ser. No. 10/707,584, filed Dec. 22, 2003.
- 1. Field of the Invention
- The present invention relates to an optical disc drive, and more specifically, to an optical disc drive which fixes the tray module within its housing.
- 2. Description of the Prior Art
- In general, the tray-in and tray-out modules of the tray module in a thin optical disc drive are operated by a dc motor or suction solenoid. Usually, the method used by the dc motor collocates the gear module with either the light sensor or the limitation switch. The dc motor mechanism is quite complete, so the cost cannot be reduced.
- In the method used by a suction solenoid, the volume of the suction solenoid mechanism is quite large. A consequence of the large size is that a suction solenoid mechanism may not be employed in an optical disc drive due to limited space in the optical disc drive unless drastic changes are made to the appearance of the product. Additionally, when the suction solenoid is not supplied with the power, the elasticity of the spring on the solenoid does not easily hold the tray-in module in a stable position. The following describes an optical disc drive that uses a suction solenoid.

optical disc drive 10 comprises ahousing 12, atray module 14 comprising atray 16, a tray-outmodule 15 set on thetray 16 for pushing thetray module 14 out of thehousing 12 with respect to the bottom of thehousing 12, and a tray-inmodule set 21 on thetray 16 for locking thetray module 14 within the housing. The tray-outmodule 15 comprises apusher 18 movably set on thetray 16, anextension spring 20 with one end fixed on thetray 16 and the other end fixed on thepusher 18. The tray-inmodule 21 comprises asolenoid 22 fixed on thetray 16, ashaft 24 fixed on the front end of thesolenoid 22, asolenoid spring 26 set on theshaft 24, ahook 28 set on the front end via theshaft 24, and apositioning point 29 set on thetray 16. - Please refer to
FIG. 3 andFIG. 4 . When thetray module 14 of theoptical disc drive 10 is in the tray-in location, theextension spring 20 is compressed according to how fartray 16 is within thehousing 12. During that time, the extension spring is capable of pushing thetray module 14 out of thehousing 12. When thesolenoid 22 is not supplied with power, thesolenoid spring 26 pushes thehook 28 to lock onto thepositioning point 29 thereby preventing thepusher 18 from pushing thetray module 14 out of thehousing 12. - Please refer to
FIG. 1 ,FIG. 3 , andFIG. 5 . The tray-out process is operated via thekey 27 on the panel of theoptical disc drive 10. When thekey 27 is pressed, theoptical disc drive 10 sends a control signal to a CPU to notify the CPU; then the CPU sends another control signal to supply thesolenoid 22 with power. When the solenoid is supplied with power, thesolenoid 22 generates a difference in magnetic force to attract theshaft 24. The magnetic force ofsolenoid 22 is larger than the thrust of thesolenoid spring 26, so thehook 28 will depart from thepositioning point 29. When thehook 28 departs from thepositioning point 29, thepusher 18 pushes thetray module 14 out of thehousing 12 15-25 mm. - However, when the suction solenoid as shown in
FIG. 1 is not supplied with power, the pushing force from thesolenoid spring 26 is not enough to hold the tray-in module. Thehook 28 and thepositioning point 29 may be separated by an external force, causing thetray module 14 to come out of thehousing 12. - It is therefore a primary objective of the claimed invention to provide an optical disc drive that is stably capable of fixing tray module within the housing.
- According to the claimed invention, an optical disc drive comprises a housing having at least one track, a positioning part fixed on the housing, and a tray module. The tray module comprises a tray installed within the housing in with the ability to slide along the track, a solenoid fixed on the tray for providing a magnetic force, a latch installed beside the solenoid for moving according to changes in the magnetic force, a push rod fixed on the tray and able to rotate with respect to a pivot with one end of the push rod connected to the latch and the other end forming a space, a hook fixed on the tray with one end for engaging the positioning part and another end connected to the push rod, a first elastic body fixed on the pivot of the push rod, and a second elastic body installed on the tray and having one end fixed in the space of the push rod.
- These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

FIG. 9 andFIG. 11 , thetray module 38 further comprises asolenoid 46 fixed on thetray 44 for providing magnetic force and alatch 48 installed beside thesolenoid 46 moving in response to changes in the magnetic force. Thesolenoid 46 comprises acoil 60 and amagnet 62. When thecoil 60 of thesolenoid 46 is supplied with power, thecoil 60 generates a magnetic force to counteract the magnetic force of themagnet 62. Countering the force from themagnet 62 frees thelatch 48 allowing it to move in response to an external force. When thesolenoid 46 is not supplied with power, thecoil 60 does not generate a magnetic force to counteract the force from themagnet 62 meaning that themagnet 62 is capable of attracting thelatch 48. - Please refer to

The tray-out operation of thetray module 38 is operated via pressing the key 39 on the panel of theoptical disc drive 30. When the key 39 is pressed, theoptical disc drive 30 sends a control signal to notify the CPU to send another control signal to supply thesolenoid 46 with power. When thecoil 60 of thesolenoid 46 is supplied with power, thecoil 60 generates a magnetic force to counteract the magnetic force of themagnet 62. As a result, thesolenoid 46 does not attract thelatch 48 allowing thecompression spring 58 to push thepush rod 52, which in turn makes the protrudingshaft 61 push thehook 54. In response to the push, the first end of thehook 54 rotates away from thepositioning shaft 50. At that moment, thecompression spring 58 starts to push thetray 44 out of thehousing 32. - Please refer to
FIG. 16 andFIG. 17 .FIG. 16 is a reverse schematic diagram of some components when atray module 38 of theoptical disc drive 30 inFIG. 6 is in the complete tray-out location.FIG. 17 is a front schematic diagram of some components when atray module 38 of theoptical disc drive 30 inFIG. 6 is in the complete tray-out location. The charging-time period of thesolenoid 46 is can be determined by the design demand of theoptical disc drive 30. In the preferred embodiment, the time-period of supplying power is very short. When thesolenoid 46 is supplied with power, thesolenoid 46 generates a magnetic force to counteract the magnetic force of themagnet 62. As a result, thesolenoid 46 does not attract thelatch 48 allowing thecompression spring 58 to push thepush rod 52, which in turn makes the push rod rotate with respect to thepivot 51 by a small angle. At that moment, the protrudingshaft 61 is links to thehook 54 causing thehook 54 to rotate by a small angle. As a result, the first end of thehook 54 departs from thepositioning shaft 50, and the compressingspring 58 pushes thetray module 38 out of thehousing 32. When thetray module 38 is pushed out of the housing 32 a little distance and thesolenoid 46 is not supplied with power, thesolenoid 46 attracts thelatch 48 to fix thepush rod 52. During this time, the protrudingshaft 61 does not move the push thehook 54. Thehook 54 is pushed by thesecond end 57 of thetorsion spring 56 to the location shown inFIG. 15 . - Please refer to
FIG. 16 andFIG. 17 again. The moment thetray module 38 is out of thehousing 32, thecompression spring 58 pushes thetray module 38 until thetray module 38 is completely out of thehousing 32, and then thecompression spring 58 gradually returns to the original length. When thetray module 38 is in complete tray-out location, thecompression spring 58 returns to the original length. - Please refer to
FIG. 16 -FIG. 19 .FIG. 18 is a reverse schematic diagram of some components when thetray module 38 of theoptical disc drive 30 inFIG. 6 is pushed within thehousing 32.FIG. 19 is a front schematic diagram of theoptical disc drive 30 inFIG. 6 when thetray module 38 is pushed within thehousing 32. When thetray module 38 is pushed within thehousing 32 from the complete tray-out location and thesolenoid 46 is not supplied with power, thesolenoid 46 can attract thelatch 48 to fix thepush rod 50. When thetray module 38 is pushed into the housing 32 a little distance, the edge of the first end of thehook 54 is edging makes contact with the positioning shaft 50 (as shown inFIG. 18 andFIG. 19 ). When thetray module 38 is pushed within thehousing 32, thehook 54 is pushed to rotate by a small angle until the first end of thehook 54 exceeds thepositioning shaft 50 thereby locking thehook 54 onto thepositioning shaft 50. The compressingspring 58 is compressed continuously until thetray module 38 is completely pushed within thehousing 32. At this time, the compression spring has maximum elongation and continuously pushes thetray module 38. - Please refer to
FIG. 20 andFIG. 21 .FIG. 20 is reverse schematic diagram of some components of thetray module 38 of theoptical disc drive 30 inFIG. 6 when thetray module 38 of theoptical disc drive 30 is in manual tray-out mode.FIG. 21 is a front diagram of some components when thetray module 38 of theoptical disc drive 30 inFIG. 6 is in the manual tray-out mode. The manual tray-out operation of the tray module is operated via a hole 31 (as displayed inFIG. 6 ). At the time thesolenoid 46 is not supplied with power, thesolenoid 46 attracts thelatch 48 to fix thepush rod 50. When a needle-shaped object moves thehook 54 via thehole 31, thehook 54 rotates by a small angle. The first end of thehook 54 departs from thepositioning shaft 50, so thecompression spring 58 pushes thetray module 38 out of thehousing 32 15-25 mm. - Compared to the prior art, the character of the solenoid in the
optical disc drive 30 in the invention along with a push rod, hook, and tray-out module is used to stably fix thetray module 38 of theoptical disc drive 30 in the tray-in location and to solve the problem in the prior art of thetray module 14 not being stably fixed within thehousing 12. Because the components in the invention are not highly dependent, the precisions of the components are not necessarily high. As a result, the assembling inaccuracy can be reduced so that the quality and the cost can be improved. The final result is the optical disc drive in the invention is a simple-mechanism with stable-operation and artistic-design. - Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
