According to this, the frame 1 constitutes the external appearance of the disc driver, and a structure for driving the disc D is provided inside the frame 1. The front plate 2 is provided at the front of the frame 1, and the front plate 2 is formed with a slot 2 'carrying the disk D.

A loading motor (not shown) for loading / unloading the disk D is installed at one side of the frame 1, and a roller 3 rotated by a driving force of the loading motor is mounted on the frame 1. It is installed horizontally inside. The roller (3) is made of a material capable of exerting a certain amount of friction while having elasticity, and rubber is generally used.

The roller 3 is supported by a roller bracket 3b. The roller bracket 3b has a spring 3s supported at one end thereof in a clockwise direction with reference to FIG. 2 around the hinge point 3h. Tends to rotate. Therefore, the roller 3 has a tendency to be in close contact with the lower surface of the disk (D).

On the other hand, when the disk D is drawn in by the roller 3 or more, a timing plate 4t operated by the disk D is provided on the mounting plate 4. In addition, a sliding rack 5 is installed at one lower side of the case 1.

5 g of driving gear parts are formed in one side of the said sliding rack 5, and the guide inclination part 5s is formed in the front-end | tip part (the roller bracket 3b side) of the sliding rack 5, and is formed. In addition, an interlocking protrusion 5t for interlocking with the timing plate 4t is formed at the rear end of the sliding rack 5. One side of the rear end of the sliding rack 5 is provided with a guide piece 6 which is bent vertically upward and has a lifting guide slot 6s.

In addition, a spindle motor 7 for rotating the disk D is installed at the inner center of the frame 1, and a turntable 7t on which the disk D is seated is disposed at the rotating shaft of the spindle motor 7. It is installed. In addition, the clamp plate 8h is provided inside the frame 1 so that the free end thereof can be lifted by a predetermined angle about the hinge pin 8h. A lifting guide protrusion 8t is formed at one side of the clamp plate 8, and the lifting guide protrusion 8t is guided by a lifting guide slot 6s formed in the guide piece 6 to clamp the plate. The lifting and lowering of (8) is made.

On the free end side of the clamp plate 8, a clamp 9 for holding a disk D seated on the turntable 7t is provided.

In the drawings, reference numeral 5p denotes a driving pin of the roller bracket, g denotes a loading gear that drives the sliding rack 5 in engagement with the driving gear portion 5g, and s denotes a detection sensor that detects insertion and withdrawal of a disk.

It will be described that the conventional disk drive device having such a configuration is operated.

In order to load the disk D, when the user inserts the disk D through the slot 2 'of the front plate 2, the detection sensor s detects the disk D and loads it. Drive the motor. When the loading motor is driven, the roller 3 rotates to move the disk D inward. At this time, the roller 3 is in close contact with the lower surface of the disk (D) by the elastic force of the spring (3s) to move the disk (D).

When the disk D is inserted to be positioned above the turntable 7t, the timing plate 4t is moved in the direction of arrow A in FIG. 1 by the insertion force of the disk D. As shown in FIG. When the timing plate 4t is moved for a predetermined period, the sliding rack 5 is moved while interlocking with the interlocking protrusion 5t of the sliding rack 5 to load the driving gear part 5g of the sliding rack 5. The gear g is engaged to move the sliding rack 5 by the driving force of the loading motor.

When the sliding rack 5 is moved, the interlocking pin 5p of the roller bracket 3b is guided along the guide inclined portion 5s and the roller bracket 3b is lowered about the hinge pin 3h. As a result, the lower surface of the disk D is no longer supported, and the disk D is seated on the turntable 7t.

At the same time, while the lifting guide projection 8t is guided to the lifting guide slot 6s of the guide piece 6 of the sliding rack 5, the clamp plate 8 is lowered about the hinge pin 8h, The clamp 9 clamps the disk D seated on the turntable 7t. The unloading operation is performed in the opposite manner to the loading operation.

However, the prior art as described above has the following problems.

First, in moving the disk D, there is a problem in that the disk D cannot be accurately moved to a desired position. This is because, when the disk D is moved by the roller 3, the disk D cannot be accurately guided. Of course, many configurations for guiding the disk D in the process of moving the disk D have been disclosed, but the exact position (the center of the disk D is the turntable 7t without acting as a load on the movement of the disk D). This is because the disk D could not be guided to a position coming to the center of the circle).

That is, when the structure for guiding the disk D acts as one load during the movement of the disk D, a lot of load is applied to the roller 3 so that the roller 3 wears out and its life decreases and wears out. Problems arise when the powdered powder is buried in the signal recording surface of the disc D, and an error occurs when reading the recorded signal or recording the signal. In addition, when the roller 3 is worn, there is a problem that the transfer of the disk D is not made accurately.

In addition, the conventional configuration as described above is large in size and does not meet the recent trend of light and thin, and there is a problem that only a disk D (for example, 12cm or 8cm) of a specific size should be used. .

It is therefore an object of the present invention to solve the problems of the prior art as described above, and to provide a disk conveying apparatus which can accurately guide a disk when the disk is moved.

Another object of the present invention is to provide a light and short disk driver.

It is still another object of the present invention to provide a disk conveying apparatus that allows a disk of different diameters to be used in one disk driver.
