Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a disk autoloading device and is suitable for optical reading devices and the like.

(B) Conventional technology In recent years, optical disks have been used as disks for high-density recording and playback.In order to protect the surface from scratches, dust, etc., optical disks are stored in cartridges, and used for recording and playback. It is desirable to be able to load the device automatically.

By the way, in such an automatic disk loading device, the disk is first held in a holder higher than the turntable, and after the holder is inserted into the device, the holder is lowered and the disk is placed on the turntable. must be installed. Therefore, two motors are required to drive the holder horizontally and vertically, and the operation timing of both motors must be precisely controlled, resulting in an increase in the number of parts and the complexity of controlling the operation timing. .

Therefore, as seen in Japanese Patent Application Laid-Open No. 59-110069, a first mechanism part that slides a holder frame housing a disk holder, and a second mechanism part that moves a frame body provided above the holder frame up and down. The structure includes a mechanism section and a single drive mechanism section that sequentially operates the first and second mechanism sections, thereby reducing the number of parts.

(c) Problems to be solved by the invention Even in the above-described configuration, the single drive mechanism section must slide and move the first and second mechanism sections up and down in a well-timed manner. Timing control is complicated.

(d) Means for Solving the Problems The disk autoloading device according to the present invention includes a first holder that holds a disk cartridge, a second holder that slidably holds the first holder, and one end of the disk autoloading device. a holder arm rotatably supported by the frame and pivotally holding the second holder at the other end, and a clamp arm rotatably supported by the frame, which are linearly movable; Along with this movement, a first slide rack that engages with and rotates the clamp arm and rotates the holder arm is linearly movable and engages with the first holder. the second slide rack, and the first slide rack.
and a drive unit for moving a second slide rack, and when the second slide rack is moved, the first holder moves horizontally within the second holder together with the disk cartridge, As the first slide rack is moved, the holder arm rotates, and the second holder rotates, lowering the first holder and the disk cartridge;
The present invention is characterized in that the clamp arm is configured to be rotated onto the disk cartridge.

(E) Effect According to the present invention, the disk cartridge can be moved horizontally and vertically by a single drive unit;
Rotation of the clamp arm (ie, clamp arm movement) can be performed.

(F) Embodiment FIGS. 1 and 2 are a perspective view and a front sectional view showing an embodiment of the present invention.

1 is a box-shaped disk cartridge made of resin or the like and stores a disk (not shown) therein; 2 is a frame-shaped first holder for holding the disk cartridge; It has a first slide pin 3 at. Reference numeral 4 denotes a frame-shaped second holder longer than the first holder 2, which slidably holds the first holder 2 with first slide pins 3 engaged with elongated holes 5 bored on both sides. Reference numeral 6 denotes a holder arm having a U-shaped cross section and arranged to cover the front upper part of the second holder 4, and swingably holds both sides of the second holder 4 at approximately the center with support shafts 7 on both sides of the rear end. do. Reference numeral 8 denotes support legs that are provided hanging down from both sides of the rear end of the holder arm 6, and a rotating roller 9 is provided at the tip. Reference numeral 10 denotes a shaft that rotatably supports both sides of the tip of the holder arm 6 on the frame 11.

12 has its upper surface in contact with the rotating roller 9, and the first
A long plate-shaped first slide rack arranged parallel to the holder 2, which has a downwardly inclined portion 12 on the front upper surface.
It has a. Furthermore, a second slide pin 13 and a hook pin 14 are provided at the center of the side surface and at the rear end of the first slide rack 12. 15 is the first
A first gear rack 16 provided on the lower surface of the slide rack 12 is a drive section consisting of a drive gear 17, a driven gear 18, and a drive motor 19 that mesh with the gear rack. Reference numeral 20 denotes a second slide rack in the shape of a rectangular plate, which has an elongated hole 21 in the vertical direction that engages with the first slide pin 3 and an elongated hole 22 in the horizontal direction that engages with the second slide pin 13. A second gear rack 23 is provided on the lower surface of the second slide rack 20 and meshes with the drive gear 17. Thus, when the drive motor 19 rotates, the first and second
Slide racks 12, 20 move linearly.
The second slide rack 20 is slidably held on both sides by holding members (not shown).

24, the hanging parts 25 on both sides of the rear end are frame 1
1 is rotatably supported by a shaft 27, and the tip of the hanging portion 25 has an engaging arm 26 that abuts and engages with the hook pin 14. 28 is a spring that urges the clamp arm 24 to rotate clockwise about the shaft 27, and 29 is a clamper provided on the lower surface of the tip of the clamp arm 24.

Further, reference numeral 30 denotes a support stand disposed to face the entire lower surface of the disk cartridge 1 at the scheduled set position, and reference numeral 31 denotes a rotation shaft 32 located approximately in the center of the support stand.
A motor 33 is disposed on the upper surface of the support base 30 and is arranged so as to protrude upward from the disk cartridge 1.
It is a holding leg that holds.

The disk cartridge 1 has a circular opening (not shown) in the center of both its upper and lower surfaces.

The autoloading operation of the disk cartridge in such a configuration will now be explained.

First, the disk cartridge 1 is inserted into the first holder 2 from its front opening to its rear end. When the drive motor 19 is driven in such a state and the drive gear 17 is rotated clockwise, the first and second
Both slide racks 12 and 20 move linearly to the right. As the second slide rack 20 moves, the first holder 2, which has the first slide pin 3 that engages with the elongated hole 21 in the vertical direction, moves rightward within the second holder 4 along the elongated hole 5. . This movement continues until the second gear rack 23 and drive gear 17 are disengaged. That is, the amount of movement of the first holder 2 is regulated by the movement of the second slide rack 12. Further, as the first slide rack 12 moves, the contact position of the rotating roller 9 changes from the horizontal part of the upper surface of the first slide rack 12 to the inclined part 12a.
Displaced to. Then, the rotating roller 9
As you go down the axis 1, the holder arm 6
Rotate clockwise around 0. By this,
The first holder 2 is lowered together with the second holder 4 by the slide pin 3 being guided into the elongated hole 21, so that the disk cartridge 1 is moved by the motor 31 to the center of the internal disk through its central opening. The rotary shaft 32 of is now inserted.

Furthermore, the first slide rack 12 is guided by the elongated hole 22 and moves, and the hook pin 14 provided at one end of the first slide rack 12 comes into contact with the engaging arm 26.
The clamp arm 24 is rotated counterclockwise about the shaft 27, and the clamper 29 is lowered onto the disk cartridge 1. As a result, the disk cartridge 1, which has been lowered together with the first and second holders 2 and 4, is set in a predetermined position, and the disks inside are clamped. At this time, the holding legs 33 restrict the descent of the disk cartridge 1.

By the way, when the disk cartridge 1 is to be taken out, the drive motor 19 is driven counterclockwise to perform the operation completely opposite to the above-mentioned operation, and the disk cartridge 1 can be taken out easily.

(g) Effects of the invention As is clear from the above explanation, the invention has two
By regulating the movement direction of each holder to either the horizontal or vertical direction, the disk cartridge can be moved horizontally and vertically using only a linear drive from a single drive unit. The timing of these movements can be easily controlled.
