Problems to be Solved by the Invention As described above, in the conventional device, the loading method is large in the recording disk that is handled as it is such as a CD and the recording disk that is handled while being stored in the cartridge like the magneto-optical disk 39. Unlike this, it was difficult to handle all of them with one device. On the other hand, there is a possibility that the recording / reproducing means itself can be sufficiently used, and it has been a great challenge to realize a device that can also be used as these recording disks.

In view of the above problems, it is an object of the present invention to provide a recording / reproducing apparatus which has a simple structure and is capable of using both a recording disc that is handled as it is and a recording disc that is handled while being stored in a cartridge.

Means for Solving the Problems To achieve this object, the present invention is used in a state where a first recording disk (for example, a magneto-optical disk 39) that is used as it is in a cartridge and is not housed in a cartridge. At least two types of recording discs of a second recording disc (for example, CD, CD-ROM) are used, and a motor for engaging these recording discs to rotate them and a cartridge for the first recording disc are used. Holding means for holding and moving substantially parallel to the rotation axis of the motor, and holding means for holding the second recording disk supported by the holding means so as to slide in a direction substantially perpendicular to the rotation axis of the motor. And a transfer table.

According to the present invention, when the first recording disk is used, the holding means holds the recording disk to load the recording disk into the apparatus when the first recording disk is used, and when the second recording disk is used, it is mounted on the transfer table. It is designed to be mounted and loaded into the device.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 1 is a holding means, 2 is a transfer table, 3 is a holding part formed on the transfer table, and a through hole formed in the transfer table,
Reference numeral 5 is a lever attached to the transfer table, which is a pin for engaging with the notch 38 of the cartridge, and 7 is a roller which is rotated by a drive motor 10, and is connected to a roller 8 and a shaft 9. The motor 10 is fixed to the chassis 11 by stays 16. 18 is a rubber roller, as shown in FIG. 5, is a metal fitting 17 so that the rotation of the roller 7 or 8 can be transmitted.
Installed in 11. The holding means 1 is provided with a guide portion 1a for guiding the transfer table 2.

Similar to the conventional example, the slider 14 has a cam groove 15 and is configured to engage with the pins 12 and 13 to transfer the holding means 1 in the Z1Z2 direction. That is, when the slider 14 moves in the X2 direction, the holding means 1 moves down in the Z2 direction. The chassis 11 has a motor 19, a head 42 and the like as in the conventional example.

First, the case of using the first recording disk 39 will be described. 2 to 5 are diagrams for explaining the operation.
Here, 21 is a rotation fulcrum of the lever 5, 22 is a pin 23 attached to the lever 5, a spring urging the lever 5 in the direction of arrow A, and 5a is a slope formed on the lever 5. As shown in FIG. 2, when the user places the cartridge 35 on the transfer table 2, the cartridge 35 and the pin 22 come into contact with each other. Then the user X1
When the cartridge 35 is pushed in the direction, the state shown in FIG. 3 is obtained. That is, when the pin 22 is pushed, the lever 5 is rotated and the pin 6 is inserted into the notch 38. Further cartridge
When 35 is pushed in the X1 direction, the state shown in Fig. 4 is obtained. That is, the slope 5a is restricted by the inner surface of the holding member 1, and the lever 5 is kept in the state shown in the figure. At this time, the reflective photosensor 20 detects the transfer table 2 and controls the drive motor 10 to rotate. This control is performed by a general microcomputer or control circuit. Then, in the initial state, the transfer table 2 is in the position raised in the Z1 direction as shown in FIG. 5A, so that the rotation of the drive motor 10 is transmitted by the roller 8 and the rubber roller 18 and transferred in the Z1 direction. When the center hole 40 of the recording disk comes directly above the motor 19, the slider 14 is moved to X2 by the urging force of the spring (the spring is not shown. This operation is a so-called latching mechanism, but the explanation is omitted.). The holding means 1 descends in the Z2 direction by sliding in the direction, and the restriction holes 36, 37 engage with the engaging pin 41 shown in FIG. 8 through the through hole 4 to hold the cartridge 35. The cartridge 35 is sandwiched between the transfer table 2 and the holding means 1. (Fifth
At this time, the memory disk 39 and the motor 19 are engaged with each other to complete the loading. In this state, the rubber roller 18 and the transfer table 2 are separated from each other as shown in FIG. That is, rubber roller
18 contacts the transfer table 2 only when it is necessary to transfer the transfer table 2 in the X1X2 direction.

Next, loading of the second recording disk 27 will be described. The transfer table 2 is provided with a holding portion 3 which is slightly larger than the recording disk and is recessed in a circular shape. The center of the holding part 3 is the center of the recording disk 39 when the cartridge 35 is placed on the transfer table and the state shown in FIG. Almost matches. Therefore, the user can load the recording disk 27 in the same manner only by placing the recording disk 27 on the holding portion 3 and then causing the apparatus to perform the same operation as when the recording disk 39 is loaded.

As described above, according to the present invention, the motor that engages with the recording disk to rotate the recording disk, the holding unit that holds the cartridge of the first recording disk and moves substantially parallel to the rotation axis of the motor,
The first recording disk housed in a cartridge is used, which has a transfer table that is supported by the holding means so as to slide in a direction substantially perpendicular to the rotation axis of the motor and has a holding portion that holds the second recording disk. Sometimes the recording disk is held and loaded so as to be sandwiched between the holding means and the transfer table, and when the second recording disk which is handled as it is is used, the recording disk is placed on the holding section of the transfer table and loaded. The usage is almost the same as the conventional dedicated device for each recording disk, there is no discomfort, no dedicated adapter is used, and the configuration is relatively simple. There is something.
