Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a disc-shaped recording medium (hereinafter referred to as a disc).
The present invention relates to an information recording and reproducing apparatus that records information on a surface and reproduces the recorded information.

[Conventional technology]

With the development of today's electronics, information recording and reproducing devices that can randomly record, reproduce, or erase audio or picture information with high performance using source beams such as Raded light have been commercialized. . For example, in an optical video disc device, an optical head detects the protrusion (pit) on the surface of an F4 disk-shaped recording medium made of transparent acrylic resin, etc., and converts it photoelectrically. After properly adjusting the gain and converting the signal into a predetermined analog value via a reproducing circuit such as a DA converter, the signal is output to an output device such as a speaker or a CRT. In this way, the desired sound or color image can be obtained instantaneously and with high performance.

Although the information recording/reproducing apparatus exemplified above has high performance and high quality, its operability is behind the above-mentioned performance. In other words, conventional disk loading/unloading operations are generally classified into two types: a method using a single disk (disc method) and a method using a cartridge containing a disc (cartridge method). The attachment/detachment mechanism also had a different structure to match these types. However, in one device, only one of the disk method and the cartridge method can be selectively used, and in reality, two information recording and reproducing devices are installed to be compatible with both the disk method and the cartridge method. It takes a lot of effort to sort the disks or cartridges and then load and unload them into the respective devices. This required a huge amount of time and effort, and it was not possible to respond appropriately and efficiently to the increasing number of recording media disks or cartridges that accompany today's increasing amount of information in terms of operability for searching and loading/unloading. .

[Problem that the invention seeks to solve]

As described above, when using the cartridge and disk system, two different types of equipment are required, which requires a great deal of cost and causes inconvenience to the operator when searching, loading and unloading operations. Therefore, by providing one or more loading/unloading ports in one information recording/reproducing device, it is possible to install/unload in more than one direction while keeping the device fixed.
There has been a demand for the development of a compatible information recording and reproducing device that can be used for both IJ and disc systems.

[Means for solving problems]

The present invention provides means for mounting and removing both a disc-shaped recording medium and a cartridge in which the disc-shaped recording medium is installed. Furthermore, one or more mounting/demounting ports are provided.

〔Example〕

Hereinafter, specific embodiments of the information recording/reproducing apparatus of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the structure of an embodiment of the present invention.

The information recording/reproducing device 1o that processes optical information on a disc-shaped disk 2 at high speed has a memory that is made into a small module using an optical head that detects optical information and converts it into an electrical signal, an IC, etc.
Conversion and reproduction circuits, etc. and circuits for controlling various servo actuators are built into the disc, and optical information on the disc surface can be randomly recorded, reproduced, or erased.

There is also a loading/unloading port 11 (one in this embodiment, but the number may be increased to multiple if necessary) for installing a disk or cartridge from the outside at a predetermined optical information detection position 111 of the information recording/reproducing device 10. ) is provided. In addition, one-touch cartridge type S is installed on the outside.
Mode switch 1 that can select 1 or disk method S
6 is attached and connected to a cartridge type or disk type operating mechanism via a selection circuit, so that the desired type can be selected immediately.

On the other hand, what is the mounting table 101 for stably mounting the illustrated disc 2 and the cartridge 12 that houses the disc 2 and protects it? 4. The disc groove 15 and the cartridge support plate 40 are formed in a shape and depth that are adapted to the external dimensions of the disc 2 and the cartridge 12.

This allows the cartridge 12 to be placed at the four points A, B, C, and
The disc 2 is properly fixed at a predetermined position of D, and the disc 2 is also appropriately fitted into the disc groove 15.

Furthermore, the loading platform 10m has 2 disks or 12 cartridges.
In order to accurately send and return the optical information to a predetermined optical information detection position 111 of the device 10 through the attachment/detachment port 11, a guide member 57 and a loading member 13 are formed, and the entire body is made of lightweight material such as synthetic resin. It has become a structured trap.

In a configuration like Oki, when using the disk method, after the desired disk 2 is fixed in the disk-shaped '7'' 4-screw groove 15 of the mounting table 10m, the -7-4 ringing member 13 is inserted into the U to U in the figure. By press-fitting or pushing out in the υ' direction, it is properly guided by the guide member 57 and can be smoothly installed and removed.Also, in the case of the cartridge method, the desired cartridge is placed on the square of the 10m mounting table. Cartridge support plate 40
After the loader member 13 is fixed to U-U' in the figure
By press-fitting or pushing out in the direction, it can be smoothly attached and detached. Even when the shapes of the disks 2 and cartridges 12 are different, a large number of mounting tables 10m each consisting of disk grooves 15 and cartridge support plates 40 of corresponding sizes are prepared. 12 is always adaptable. Furthermore, since it has an integrated structure, it can be easily cleaned and even fine dust can be removed.

FIG. 2 is a perspective view showing the detailed structure and mounting function of the cartridge support plate (or 7" 4-screw groove) feeding mechanism of the information recording and reproducing apparatus of the present invention. A motor 61 is connected to a gear (pinion) 62. The gear 62 and the rack 63 fixed to the guide member 57 are configured to mesh with each other.The guide member 57 also has a structure in which the guide member 57 has an attachment direction U and an attachment direction U' depending on the length of the hole. A guide elongated hole 58 and a cartridge support plate 40 whose respective linear sliding amounts are determined.
It has a structure consisting of a fixing pin 159 for fixing the cartridge support plate 40 by a predetermined sliding amount, and a fixing pin 66 for fixing the cartridge support plate 40 by a predetermined sliding movement in the vertical directions v to v'. The cartridge support plate 40 has a light IJl structure and has an S-shaped elongated 68 (not shown in the figure, but 4 It has a structure with holes (there are several). The cartridge support plate 40 and the guide member 57 are configured to slide together in the U%U' direction. Further, a slide member 64 is provided so that the cartridge support plate 40 is accurately fixed at a predetermined optical information detection position of the information recording/reproducing apparatus when it is lowered in the V' direction. are engaged with each other and brought into close contact with each other. In the above components, the same number of each element (for example, four in the case of the fixing pin 66) are provided at symmetrical positions in the sliding direction U-U'. 40
is designed to operate smoothly.

The mounting function of these configurations will be explained.The mounting direction is the U direction.Currently, a desired cartridge or disk is mounted on the cartridge support plate 40 or the F4 disk groove 15, and the desired cartridge or disk is placed in the predetermined position of the information recording/reproducing apparatus. It is about to be sent to the optical information detection position. In this condition, motor 6
1 in the W1 direction, the gear 62 and the rack 63 rotate and move, and the guide member 57 is linearly guided by the fixed pin 59 in the mounting direction U and slid to a predetermined position. In this case, the movement of the cartridge support plate 40 is prevented by the pivoted mounting pin 69 in FIG.
The cartridge support plate 40 is adapted to be stopped. On the other hand, the slide member 57 is slid to the position of the fixing pin 59 by the rotation of the motor 61, and in conjunction with this, the cartridge support plate 40 is smoothly moved downward V' along the S-shaped elongate 68. As shown in FIG. 3, the end face 1 plate and the end face al of the fixed 1242 member 40 are brought into close contact and fixed, and the mounting operation is completed.

3 and 4 are a perspective view and a front view for explaining the attachment/detachment function of the cartridge support plate (or disk groove) feeding mechanism of the information recording/reproducing apparatus of the present invention. The attachment/detachment direction is U.
' direction, the cartridge support plate 40 or disk groove 15 is currently loaded with an IJ or disk for which information has been detected, and is being moved outside the information recording/reproducing apparatus to detect the next information. I am about to receive a weekly salary. In this state, as shown in FIG.
The cartridge support plate 40, which had been fixed in a predetermined position with the mounting bolts 69 shown in FIG. 1 and FIG.
3 is rotated and moved, and the guide member 57 is moved in the attachment/detachment direction U'.
It is guided by a fixed pin 59 and slid linearly by a predetermined amount.

Accordingly, the fixing pin 66 is moved downward as shown in FIG.
It is moved along the letter-shaped elongated hole 68. On the other hand, since the cartridge support plate 40 is prevented from moving in the U' direction by the slide member 64, the movement height H of the fixing pin 66 is
Only end face a! It is moved smoothly upward along ■ U
It can be slid freely in / direction. Thereafter, the cartridge support plate 40 and the guide member 57 are integrated. Then, as the motor 62 rotates, it is accurately guided by the fixed pin 59 and slides linearly in the attachment/detachment direction U' along the guide elongated hole 58, thereby completing the attachment/detachment operation.

The attachment/detachment mechanism and operation of the above-mentioned embodiment are carried out easily by the same information recording and reproducing apparatus in the case of the cartridge type using a cartridge, but also in the case of the disk type using a disk directly.

That is, after a desired disk is placed in the disk groove, the above-mentioned loading/unloading operation is performed by selecting the disk mode with the mode switch. In this case, the only difference between the cartridge method and the disk method is the moving height H shown in FIG. 4, so a control mechanism is selected that appropriately changes the rotation speed of the motor in both to appropriately adjust the amount of movement of the fixed pin 59. It is provided via a circuit.

FIG. 5 is a perspective view showing the detailed structure and function of the mounting plate vertical feeding mechanism. In order to accurately fix the disk 2 or cartridge 12 in a predetermined position, it is necessary to press the cartridge or disk on the cartridge support plate or disk groove from above.

For this reason, a clamp member 44 having an inner diameter that can be brought into close contact with the circular hole 2as of the disk 2 is attached to the bearing 4 shown in FIG.
It is connected to the mounting plate 45 via 8. Also, mounting plate 4
5 has a structure including a drive motor 70m and 70b%, a gear (pinion) 71, and a rack 72 so as to be slid in the vertical direction V to 1/2 as shown in the figure. The functions of the above configuration will be explained below. When setting the disc 2, the circular hole 2am of the disc 2 is fixed to the clamp member 44, and the motor 70&.

By simultaneously rotating the gears 70b in the W direction, the gear 71
rotates, the rack moves in the V' direction, and is clamped and set at the center of a centering member 49, which will be described later, via a bearing 48.

In the case of ejection, conversely to the above, motor 701゜70b
It can be easily ejected by rotating it in the W' direction.

Figure 6 is a sectional view showing the structure of the mounting mechanism.

The IJ (disc or car) is fed to the information recording/reproducing apparatus of the present invention through the loading/unloading port, and is accurately set at the optical information detection position by the feeding mechanism shown in FIGS. 2 to 5. Indicates a state in which The center of the disc-shaped disk 2 is the center E of the rotation shaft 47 of the drive motor 41 such as a spindle motor.
-E' is set accurately, and the structure is such that rotational deviation does not occur. The disk 2 and car IJ edge 12 placed on the disk support plate 40 are closely connected to the positioning member 43 so as not to shift in the left-right U-U' direction.

Further, the disc 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' direction, and furthermore, at two points in the figure, the clamp member 44 and the turntable 42 are used. 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 clamp 44 as a shock absorber, the rotational movement is cut into the clamp 44, and the rotational movement is The structure is such that it is not transmitted to the mechanism. Further, the positioning member 43 is normally held in a raised state by a spring 46, and when it is installed, the contraction of the spring 46 allows it to absorb the looseness of the inner diameter of the disk and various parts.

As described above, the information recording and reproducing apparatus of the present invention can be used for both the disk type and the cartridge type.

Note that by using an automatic cartridge or disk search device in this embodiment, the search and loading/unloading operations are automated, and more efficient information processing becomes possible. Furthermore, it is also easy to provide a plurality of loading/unloading ports for loading and unloading cartridges or disks for faster information processing.

〔Effect of the invention〕

As described above, according to the present invention, with a simple and inexpensive structure,
It is possible to provide an information recording and reproducing device that has many advantages, such as being able to quickly and reliably record, reproduce, and erase a large amount of today's information by being able to attach and detach both a disk and a cartridge at any time. .
