Description

More particularly, the present invention relates to an emergency eject device that forcibly ejects an optical disk in the event of a failure or power failure of the slot loading optical disk drive.

Optical disc drives are classified according to the loading and unloading format of the disc, and are generally divided into two types, a tray loading method (Tray-type) and a slot loading method (Slot-in). The tray loading type optical disk drive loads and removes the optical disk by the tray, and when the optical disk drive loses its function, the tray is ejected and the disk is ejected only by contacting the tray locking mechanism. it can. The slot loading type optical disk drive guides the insertion / removal of the optical disk by interlocking the lever, roller or toothed belt with a gear device. However, when the function is lost, the optical disk cannot be ejected from the optical disk drive. The optical disk can be taken out by removing the drive housing. However, disassembling a precise slot loading optical disc drive is very difficult for general users, especially in the case of slot loading optical disc drives for automobile audio, computers or high-end audiovisual equipment. Then, the main device is disassembled, and then the slot loading type optical disc drive is further disassembled, whereby the optical disc can be taken out. As a result, the emergency ejection of the slot loading type optical disk drive is very inconvenient.

In order to solve the problem that the emergency ejection of the slot loading type optical disk drive is not easy, as shown in FIG. 1, there is a forced slot-in ejection device of the slot loading type optical disk drive disclosed in Patent Document 1, the conventional ejection device. 1, the power supply unit includes a power supply unit for rotating the drive gear 2 installed in the front part of the eject device 1, and the control for using the rotation of the power supply unit on the eject device 1 for starting or stopping A switch 3 is provided separately. Thereafter, the drive gear 2 at the front part of the ejecting device 1 is inserted into the positioning hole 5 at the front part of the slot loading type optical disk drive 4, so that the motor gear of the optical disk drive 4 attached to the vicinity of the positioning hole 5 is fixed. By engaging with the ON gear, and further turning on the control switch 3 to rotate the drive gear 2 and interlocking with the pinion gear of the optical disc drive 4 motor, the optical disc drive 4 performs the ejection operation, making it easier to take out the optical disc. Is ejected from the optical disk drive through the slot 6.

The conventional ejecting device 1 can be forcibly ejected from the optical disk drive, but the ejecting device 1 is a special tool that rotates the structure of the front drive gear 2 by electric power, not a general-purpose tool that can be obtained anywhere, and When general consumers use an optical disk drive, they do not bother to purchase a separate eject device, and do not always carry a heavy eject device. As a result, when the optical disk drive fails or loses its function, it is impossible to find a suitable tool in real time. Therefore, the optical disk drive is also sent for repair, and the specialist is disassembled to disassemble the main device and take out the optical disk. Even a professional repair engineer cannot forcibly eject the slot loading type optical disk drive from the slot with a general tool, and can easily remove the optical disk by always including an ejecting device. Otherwise, the main device must be disassembled and the optical disc removed.

Furthermore, since the conventional slot loading type optical disk drive is loaded and unloaded by the multiple gear devices, the torque difference between the output side and the output side of the gear device is not only very large, but also the rotational speed changes Very big. Driving the gear device of the slot loading type optical disk drive by rotating the pinion gear of the motor with the ejecting device requires not only relatively large power but also ejecting by rotating the gear device of the optical disk drive for a certain period of time. Can not be ejected speedily. As a result, the conventional slot loading type optical disc drive ejecting device has a great limitation in use, and a solution has been awaited.

By inserting the thin rod 40 into the through hole 28, the emergency eject device 30 of the present invention can be contacted. FIG. 3 is a locally enlarged view of the rear surface of the transmission gear set 22 of the slot loading type optical disk drive 20. The first gear 222, the second gear 223, and the third gear 224 are composed of large and small gears, and the large and small gears are engaged with each other. The first gear 222 and the worm gear 221 on the rotation shaft of the drive motor 21 are meshed with each other, and the small gear of the third gear 224 is meshed with the gear rack of the sliding member 225. The central axes of the gear 222 and the third gear 224 are fixed to the slot loading type optical disc drive 20, respectively. The emergency eject device 30 of the present invention is provided on the back surface of the transmission gear set 22 and mainly includes a rotating plate 31, an elastic body 32, and a guide groove 33. Three holes such as a fixed hole 34, a moving hole 35, and a support hole 36 are formed at equal intervals on the rotating plate 31, and the fixed hole 34 penetrates from the central axis of the first gear 222 to form the first gear and the slot loading method. By fixing the optical disk drive 20 so that it can rotate at the same time, the rotating plate 31 can freely rotate about the fixed hole 34. The movement hole 35 is used to fix the central axis of the second gear 223. The second gear 223 moves with the movement hole 35 around the fixed hole 34 to form a movable gear. While the second gear 223 is moving, the large gear is always kept in mesh with the small gear of the first gear 222.

In addition, one end of the elastic body 32 of the emergency eject device 30 is fixed to the slot loading type optical disc drive 20 and the other end is connected to the support hole 36. By elastically supporting the elastic body 32 in the direction in which the force of the support hole 36 is applied, the second gear 223 meshes closely with the first gear 222 and the third gear 224 with the fixing hole 34 of the emergency eject device 30 as a fulcrum. Can be made. Conversely, the third gear 224 engaged with the small gear of the second gear 223 can be disengaged by resisting in the rotational direction of the elastic body 32 of the elastic body 32 of the emergency eject device 30. In addition, a contact surface 37 is provided on the side edge of the rotating plate 31, the contact surface 37 is bent at the side edge of the rotating plate 31, and the contact surface 37 is a path through which the thin rod 40 is inserted into the through hole 28.

In addition to the through-hole 28 guiding the thin rod 40 and pushing the contact surface 37, the emergency eject device 30 has a guide groove 33 extending to one end of the sliding member 225 in the path for inserting the thin rod 40 into the through-hole 28. By installing, the thin rod 40 can be guided to push the contact surface 37 and contact the contact portion 226 on the sliding member 225.

FIG. 4 shows a state where the slot ejecting optical disk drive 20 is in a state where the function is lost due to a failure or a power failure in the operation state of the emergency ejecting apparatus 30 of the present invention. Is inserted, the through hole 28 and the guide groove 33 are guided, the thin rod 40 comes into contact with the contact surface 37 and pushes the contact surface 37, and the rotating plate 31 is centered on the central axis of the first gear 222. By rotating, it resists the elastic force of the elastic body 32, forcibly disengages the small gear of the second gear 223 from the meshing of the third gear 224, and disengages the transmission force of the transmission gear set 22 back and forth, In addition to reducing the number of gears required for rotation, it is also necessary for ejection by blocking the low-speed transmission gear resistance force with relatively large torque, such as the worm gear 221, for example. Reduce the forces. Next, in a state in which the third gear 224 engaged with the second gear 223 is disengaged and maintained, the thin rod 40 is continuously inserted into the back to contact the contact portion 226 on the sliding member 225, and the thin rod 40, the abutting part 226 is moved to push the sliding member 225 forward. At this time, the sliding member 225 rotates only the third gear 224 of the transmission gear set 22 so that the resistance force can be greatly reduced. And the time required for the rotational speed of the gear ratio can be reduced, so that the sliding member 225 can directly drive the lowering of the core 25, so that the spindle motor 251 releases the optical disk, and the positioning mechanism 24 is The purpose of pushing and pushing out the optical disc to eject it quickly can be achieved.
