By providing the opening 16, a wall can be formed on the front surface of the tray 12, and a cover for preventing dust and foreign matter insertion and another part of the lock mechanism are not required on the exterior panel side.

FIG. 7 is an enlarged perspective view of the rotation lock member 19a provided on the side surface of the frame main body 11 in the direction in which the disk is inserted in FIG. The bare disk or the cartridge containing the disk is transferred in the direction of arrow E by pushing the tray. At this time, the rotation lock member 19a rotates in the direction of the arrow 19a, and the bare disk or the cartridge is sandwiched between the rotation lock member 19b. When the bare disk is inserted, holding a bare disk in the first projection side surface portion 71a of the rotation lock member 19 a, when the cartridge is inserted, and the first protrusion side surface portion 71a, the The cartridge is held down by the upper surface 72a of the protrusion 1 of the first protrusion. The first protrusion side surface portion 71a and the first protrusion upper surface portion 72a are referred to as a first protrusion portion.

  When the bare disk is placed on the tray and inserted into the frame body with the tray 12 placed horizontally, the optical pickup unit 15 is inserted into the frame body by a predetermined mechanism. Operates to be close to.

  In the lower part of the rotation lock member 19a, a second protrusion 74a whose upper surface is inclined inward in FIG. 7 is provided. As described above, when the optical pickup unit 15 approaches the bare disk, the rotation lock member 19a rotates, and the second projection 74a holds the cartridge or the like. The rotation lock member 19b is also a member having a similar structure.

  The operation of this embodiment of the invention will now be described. First, a case where a bare disk is inserted with the disk drive apparatus shown in FIG. 1 placed vertically will be described. A bare disk 40 is placed in the disk mounting portion 13 of the tray 12. Then, as shown in FIG. 8, the bare disk 40 is not completely placed on the disk placing portion 13 and is held by the disk holding members 14b and 14c.

  In this state, when the front surface 23 of the tray 12 is pressed or the open / close button is pressed, the tray 12 is transferred in the direction of arrow H while holding the bare disk 40 and enters the frame body 11. At this time, the edge portion of the bare disk 40 hits the first projecting side surface portion 71b of the rotation lock member 19b, resulting in a state as shown in FIG.

  In addition, as shown in FIG. 12, in a state where the tray 12 is not completely inserted into the frame main body 11, the optical pickup lifting / lowering unit 82 is below (a position away from the surface where the bare disk is inserted). Next, as shown in FIG. 9, when the bare disk is transferred toward the frame body 11, the rotation lock member 19 b rotates as indicated by an arrow J, and the first protrusion side surface 71 b Hold the edge of the bare disk.

  At the same time, as shown in FIG. 13, the optical pickup lifting / lowering portion 82 is moved in the arrow K direction by a predetermined mechanism. By this operation, the optical pickup unit 15 placed on the optical pickup lifting / lowering unit 82 is brought close to the information recording surface of the transferred disc. The slope portion on the upper side of the second protrusion 74a of the rotation lock member 19a moves by the spring force while slidingly contacting a part of the optical pickup lifting / lowering portion 82.

  On the other hand, since the rotation lock member 19a operates in the same manner and holds the disk, the disk moves in the direction of arrow J in FIG. 9, and the disk is sandwiched between the rotation lock member 19b and the rotation lock member 19a.

  As described above, since the second projecting members 74a and 74b are provided below the rotation lock members 19a and 19b, the second pickup member 74a and 74b has the second protrusion when the optical pickup unit 15 placed on the mount chassis 14s moves. The rotation lock members 19a and 19b are rotated by the inclined surfaces of the projecting members 74a and 74. At the same time, the optical pickup unit 15 is locked so as to approach the bare disk 40. Therefore, the bare disk 40 is mounted with a slight movement in the arrow J direction.

  In this manner, when the optical pickup lifting / lowering unit 82 is raised (that is, the optical pickup unit 15 is brought close to the bare disk 40) by a predetermined mechanism, the rotation provided on the side surface of the frame main body in the transfer direction of the tray 12 is performed. By moving the movement lock member 19a and the rotation lock member 19b inward, the bare disk is held.

  Thereafter, the bare disk 40 is rotated by a motor to reproduce information. When the reproduction of information is finished, the rotation of the disk is stopped, and a button (not shown) is pressed to separate the optical pickup unit 15 from the bare disk 40 and transfer the tray from the frame body.

  Next, the operation in the case where the disk stored in the cartridge is reproduced with the disk drive device of this embodiment in a state where the tray is placed horizontally will be described.

  When the cartridge 51 having the left front groove 52 and the back right concave portion 53 as shown in FIG. 5 is placed on the tray 12, the disk holding members 14b and 14a are pushed by the placement of the cartridge as shown in FIG. And rotate in the direction indicated by arrow D. On the other hand, as shown in FIG. 2, the click leaf spring 21a and the click leaf spring 21b are fitted in the left front groove 52 and the rear right recess 53, respectively, and the cartridge 51 is set.

  In this state, the tray 12 is transferred into the frame body, and the cartridge is transferred in the E direction as shown in FIG. At this time, the rotation lock member 19a rotates inward, and the cartridge is regulated and held by the first protrusion upper surface portion 72a and the first protrusion side surface portion 71a.

Also at this time, the rotation lock member 19a is rotated by the upper inclined surface of the second protrusion 74a as shown in FIG. Rotate.

  In such a state, the disc is reproduced, and when the reproduction is finished, the tray is transferred from the frame body.

  According to this embodiment of the present invention, the function of holding and holding the bare disk or the cartridge by the inward rotation operation of the pair of rotation lock members and the rotation operation are interlocked with the movement of the pickup unit. There is an advantage that it is performed without requiring a special drive system (motor or the like).

  In the above embodiment of the present invention, three relatively small disk holding members provided on the tray and the cartridge biasing arm on the opposite side of the drive enable loading of the cartridge and vertical use of the bare disk. Compared to the conventional apparatus shown, the mechanism can be simplified and the number of parts can be reduced. Unlike the above-mentioned conventional apparatus, the three disk holding members provided on the tray are arranged outside the outer shape of the disk, and after the disk is transported to the frame body, the biasing arm is near the center of the disk in conjunction with the clamping operation. It is comprised so that it may transfer and clamp to.

  Therefore, even when used in a horizontally placed state, the disk can be mounted on the tray from directly above as in the case of a normal horizontal limited drive, and there is an effect that good operability can be maintained. Also, since the tray can be configured with a simple shape like a conventional bare disk drive, it is possible to form a disk cartridge extraction part on both sides of the tray and provide a foreign matter intrusion prevention wall at the front end. The movable lid and other locking mechanisms required for the panel are no longer necessary.

  In this embodiment, the cartridge / bare disk and horizontal / vertical correspondence can be achieved with a simple structure by three disk holding members supported on the tray so as to be rotatable and slidable and the cartridge biasing / disk transfer arm attached to the drive body. As a result, it was possible to save space, reduce the number of parts, and reduce costs.

  In addition, with the structure that three holding members on the tray are arranged at a position where the disk outer shape does not interfere and the tray loading is completed, the urging arm acts in conjunction with the clamping operation to transfer the bare disk to the vicinity of the center and clamp it, Bare disk installation operability equivalent to conventional bare disk drive is realized. When the cartridge is used, the three holders on the tray are retracted by being pressed by the cartridge housing and stored in the tray, and after the tray is conveyed into the drive body, the urging arm acts to urge the cartridge onto the tray. Is done.

  Further, in terms of the structure for holding the cartridge of the tray in the present invention, the cartridge is held on the tray by regulating the cartridge diagonal line by supporting the left front groove and the back right concave portion of the cartridge with two clip springs. The cartridge has a feature in a vertical holding method of the cartridge which is configured and simplified in structure and has a reduced number of parts and cost.

  In addition, the tray structure can be made as thick as a conventional bare disk drive instead of a two-piece structure, so an opening for taking out a disk cartridge can be provided on both sides of the tray center, and the conventional cartridge-compatible estimation vertical use There is no need to provide an opening at the front end of the tray found in the drive. Therefore, a fixed wall can be provided on the entire surface of the tray, and a structure that eliminates the need for a movable door and a lock mechanism for preventing the intrusion of dust and fingers / foreign substances required for the front panel of the drive exterior has become possible.

  The vertical / horizontal compatible drive for cartridges according to the present invention has the same operability as a drive dedicated to a bare disk or limited to a horizontal posture, and can reduce the number of parts and save space and cost by simplifying the mechanism.

In addition, it is configured to hold the cartridge on the tray by supporting two cartridges on the back right side recess of the left front groove of the cartridge with a click spring and regulating the cartridge diagonal line, simplifying the structure, reducing the number of parts and cost We were able to plan. In addition, this cartridge tray vertical holding method has also been made, and the operability of the cartridge can be improved with a simple structure, a reduced number of parts, space saving and low cost.

  The tray structure can be made as thick as a conventional bare disk drive instead of a two-piece structure, so an opening for disk cartridge removal can be provided on both sides of the tray center. The movable door for preventing dust intrusion and finger / foreign substance intrusion at the front end of the tray and its locking mechanism could be eliminated.

  In the above-described embodiment of the present invention, the case where a disk is inserted into the disk drive device has been described. In general, any disk-shaped recording medium may be used.

  In the above-described embodiment, the case where the optical pickup unit operates so as to be close to the desk when the tray is transferred to the frame main body has been described. However, the present invention is not necessarily required as long as the center of the disc to be transferred is mounted so as to coincide with the center at the time of reproducing the disc.
