 The present invention relates to an optical disk drive device, and more particularly to an optical disk drive device that can easily confirm an access position of an optical disk.

[0002]

[Prior art]

 Conventionally, a CD type optical disk (CD, CD-ROM, CDR, magneto-optical MD, etc.) has a structure in which a pickup is moved to a target track on the surface of a board for access. At this time, the position of the pickup is controlled by detecting the track number or sector number written in the track or sector accessed by the pickup. That is, in the conventional optical disk drive, the position of the pickup is determined based on the track information or sector information which the pickup is reading from the disk at that time. In addition, the position of the pickup is indirectly displayed by the elapsed time.

[0003]

[Problems to be solved by the device]

 As described above, the conventional optical disk drive device indirectly displays the position of the pickup based on the track information of the disk, and therefore the physical position of the pickup cannot be visually confirmed immediately. It was

The present invention has been made to solve the above-mentioned problems of the conventional technology, and an object of the present invention is to provide an optical disk drive device capable of easily confirming an access position of an optical disk.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the optical disc driving device of the present invention is an optical disc driving device in which a pickup is moved in a radial direction of an optical disc to access the optical disc. It is characterized in that it has a pointer that moves in the direction of movement and has at least the tip visible.

Further, in an optical disk drive in which the pickup moves in the radial direction of the optical disk to access it, a pointer for confirming the position of the pickup is provided, and the pointer is provided at a fulcrum provided at the center of the above-mentioned pointer. The pointer is rotatable, and the pointer is rotatable around the fulcrum with the movement of the pickup. The distance from the fulcrum to the tip of the pointer is larger than the distance from the pickup to the fulcrum. Further, it is characterized in that a mark is provided along with the displacement direction of the pointer. Further, the mark is embodied on a scale. Further, a light emitting body is arranged on the pointer.

[0007]

[Action]

 In the optical disk drive of the present invention, at least the tip of the pointer whose tip is visible is fixed to the pickup, so that the entire pointer moves in the pickup moving direction as the pickup moves. As a result, the movement of the tip of the pointer and the current position can be easily confirmed.

In addition, when the central portion of the pointer is rotatably supported by the fulcrum, the pointer rotates about the fulcrum as the pick-up movement, whereby the moving direction of the tip of the pointer. Can be reversed to the direction of movement of the pickup, which increases the degree of freedom of attachment to the optical disk drive housing. Further, by setting the distance from the fulcrum to the tip of the pointer to be larger than the distance from the pickup to the fulcrum, the movement amount of the tip of the pointer is enlarged more than the pickup movement amount, and a display that is easy to check is displayed. It will be possible.

Further, since the mark is provided in the displacement direction of the pointer, it becomes easier to confirm the displacement of the pointer, that is, the movement of the pick-up. Further, since the marks are embodied as scales, it becomes easier to confirm the position of the pointer, that is, the position of the pick-up. Further, when the luminous body is arranged on the pointer, the movement and the position can be more easily confirmed.

【Example】

 Hereinafter, the configuration and operation of the optical disk drive according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a top view of an embodiment of an optical disk drive device according to the present invention. As shown in FIG. 1, a CD player (optical disk drive device) 1 of the present invention is inserted into a spindle 8 for rotating an optical disk 9 such as a CD, a pick-up 2 for accessing the optical disk 9, and a pickup 2 so as to be freely inserted. The thread shaft 3, the thread motor 4 for moving the pickup 2 in the radial direction of the optical disk 9 along the thread shaft 3, the pinion gear 4A mounted on the axis of the thread motor 4, and the side surface of the pickup 2 mounted on the side surface of the pickup 2. A rack gear 2A meshed with the pinion gear 4A is provided.

Further, it is provided with an elongated pointer 6 whose root is attached to the pickup 2 by a joint portion 6A. The joint portion 6A is configured by screwing or welding. Further, the tip of the pointer 6 is visible through an opening of a casing (not shown).

When the thread motor 4 rotates, the pinion gear 4A also rotates in the optical disc driving apparatus having the above-described configuration, meshes with the rack gear 2A attached to the side surface of the pickup 2, and moves the rack gear 2A, that is, the pickup 2 to the arrow W1. To move in the direction. By the movement of the pickup 2, the target track of the optical disc 9 rotated by the spindle 8 is accessed. As the pickup 2 moves, the pointer 6 as a whole moves in the direction of the arrow W2. Therefore, the tip of the finger 6 also moves, and by visually confirming the position of the tip 6 of the pointer 6, the current physical position of the pick-up 2 is detected. The position is easily confirmed. Here, if the mark 7 provided with the mark 7A is provided in the displacement direction of the pointer 6, it becomes easier to confirm the displacement of the pointer 6, that is, the movement of the pickup 2.

FIG. 2 is a top view showing another embodiment of the optical disk drive device according to the present invention. As shown in FIG. 2, a CD-based player (optical disk drive device) 10 of the present invention includes: a spindle 8 for rotating an optical disk 9 such as a CD; a pickup 2 for accessing the optical disk 9; and a thread slidably inserted into the pickup 2. A shaft 3, a sled motor 4 for moving the pick-up 2 along the sled shaft 3, a pinion gear 4A attached to the shaft of the sled motor 4, and a rack gear 2A attached to the side surface of the pickup 2 and meshed with the pinion gear 4A.

Further, a long fitting hole 12A is provided at the base, and a fulcrum 11 is provided at the center, and the fitting hole 12A is provided on the pin 2B provided on the pickup 2 and the fulcrum 11 is provided on the housing. A pointer 12 is attached to each of the support shafts and is attached to the pickup 2 so as to be rotatable around the support shaft 11.

Since the fulcrum 11 at the center of the pointer 12 is rotatably supported by the fulcrum, the pointer 12 rotates about the fulcrum 11 as the pick-up 2 moves. The moving direction of the tip of the pointer 12 is opposite to the moving direction of the pickup 2. As a result, the degree of freedom in attaching the drive portion to the optical disk drive device housing increases.

Here, as shown in FIG. 2, the distance L2 from the fulcrum 11 to the tip of the pointer 12 is made larger than the distance L1 from the fitting hole 12A connected to the pickup 2 to the fulcrum 11. The amount of movement of the tip of the pointer 12 can be made larger than the amount of movement of the pickup 2. This configuration enables a display that is easy to confirm. Further, a scale 15 may be provided near the tip of the pointer 12 as shown in FIG. In this case, the tip position of the pointer 12 can be detected more precisely and easily. Further, FIG. 3 shows a configuration example in which a luminous body is arranged on the pointer. By disposing the LED 21 at the front end of the pointer 20, it becomes easier to confirm the movement and position of the tip of the pointer 20.
