Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dinucu-shaped recording medium (hereinafter referred to as a disk).
The present invention relates to an information recording and reproducing apparatus used for recording information randomly at high speed and reproducing the recorded information with high quality.

[Conventional technology]

Generally, when using an information recording/reproducing device to non-contactly record, reproduce, or erase audio or image information using a circular disk as a medium, the desired disk or a cartridge containing the disk is inserted into the loading/unloading port from the outside. It is necessary to take the information into and out of the information recording/reproducing device through.

FIG. 9 and FIG. 1O are perspective views showing the structure and function of a conventional information recording/reproducing device. The operation of attaching and detaching the Dinuk 2 using the conventional information recording and reproducing device 3 shown in FIG. After being placed, the information recording and reproducing apparatus 3 is attached to and detached from the information recording/reproducing apparatus 3 by moving the guide rail 4 in the directions S to S'. Further, a disc 2 using another conventional information recording/reproducing device 30 shown in FIG.
The attachment/detachment operation is similar to the device 3 shown in FIG.
The information recording and reproducing device 3 is attached to and detached from the information recording and reproducing device 3 by moving it in the ' direction.

[Problem that the invention seeks to solve]

However, from the table, when attaching and detaching Dinuku 2 to the two conventional devices mentioned above, the device itself is fixed in advance, and the attachment/detachment port can only be attached in one direction (for example, from S to S/ direction in the figure). However, this mounting/detaching operation may cause inconvenience to the operator. In other words, in response to today's wide variety of information, the number of disks 2 has increased, and Dinuk 2
When using a conventional device in which the mounting/detaching port 11 is fixed, the mounting/detaching operation is often complicated. Manually searching one by one for a desired disk 2 from among a large number of disks and loading it from one direction would take an enormous amount of time and effort. Further, the search and loading/unloading operations of the disk 2 are often automated by an auto-changer 20, ie, an automatic search device, shown in FIG. 7, or manualized and used accordingly. In this case, since it can only be attached and detached from one direction, the auto chain glossy 20
or vice versa, move the information recording and reproducing device to align the loading/unloading opening with the auto-changer at the predetermined position, and then set the weekly feed direction of the disk 2 of the auto-changer 20 and the information recording. Direction A or A for attaching and detaching the playback device
It is necessary to position the information recording and reproducing apparatus by accurately matching the information recording and reproducing apparatus. Therefore, there has been a demand for the development of an information recording/reproducing apparatus that can efficiently perform the loading/unloading operation of the disk 2.

[Failure to solve the problem]

The present invention was developed in view of the above-mentioned circumstances, and by making the information recording/reproducing device rotatable with a simple structure, the loading/unloading port can be positioned at a desired position, thereby allowing switching between manual and auto changer modes. This makes it possible to perform operations efficiently and to search for, load and unload disks easily and quickly.

The disk 2 and cartridge 12 placed on the disk support plate 40 are brought into close contact with a positioning member 43 so as not to be displaced in the left-right direction U-U'. In addition, the disk 2 is held in close contact with the clamp member 44 and the turntable 42 at points X and Y in the figure in order to cope with vibrations in the vertical v-v' directions. Parts of the centering member 49 have a concave structure and are closely engaged with each other to prevent deviation from the axial center E-E', and the structure is such that rotational motion is smoothly transmitted to the clamp member 44. . In this case, the disk 2 rotates at high speed around the rotation axis E-E', but since the bearing 48 is press-fitted into the crank '7' 44 as a buffer, the rotational movement is cut off and the mounting plate 45
There are many structures that are not transmitted to higher mechanisms. or,
The positioning member 43 is normally held in a lifted state by a spring 46, and when it is installed, the spring 46 contracts so that variations in the inner diameter of the disk, the thickness of the disk, and even the clamping member due to the soil can be absorbed.

FIG. 7 is a perspective view for explaining the general structure and usage example of the auto-changer 20 used in the information recording/reproducing apparatus of the present invention. The autochanger 20 has a large number of cartridges 12a=12z grouped into each stage.

In the embodiment shown in this figure, of the two mounting and dismounting directions A-A' and B-B', the A-A' direction is the mounting and dismounting direction dedicated to the auto-changer 20, and the other B-B'
The direction can be used for automatic change 20 or for manual use as appropriate.

FIG. 8 is a diagram for explaining the functions of autochanger 200. The retrieved cartridge 12 is placed on the cartridge support plate 33, and as the gear 32 rotates in the P direction, the rack 31 moves in the S direction of the feeding direction, and is stably guided by the guide member 34. The data is then easily sent to the information recording/reproducing apparatus IO through the mounting/demounting port 11.

On the other hand, in the case of attachment/detachment, recording, reproduction, or erasing processing is performed, and the cartridge 12 is moved in the 'S/ direction by the rotation of the gear 32 in the P' direction, and weekly data is received from the information recording/reproducing device IO through the attachment/detachment opening 11. , the cartridge 12 is grasped and automatically stored in a predetermined location on the cartridge rail 21.

In this embodiment, the mounting/detaching direction of the information recording/reproducing device 10 is set to A.
# Although the directions are A' and B'-B', by appropriately adjusting the rotation control angle of the motor 16 shown in FIG. It is also possible to perform attachment/detachment operations. Further, in the present embodiment, the disc mounting member 5 of the information recording/reproducing apparatus 10 is formed for use with the package 12, but it can be easily changed to use the disc 2 as shown in FIG.

〔Effect of the invention〕
