As described above, only the 8 cm DVD cartridge 6 has a different recording / reproducing height, and the 8 cm DVD shutter opener 57 is used for recording / reproducing the 12 cm DVD cartridge 1, 12 cm disk 3 and 8 cm disk 4.
Is provided with a mechanism for retracting the disc cartridges to outside the outer diameters than the 12 cm discs 2 and 3, thereby making it possible to cope with two types of disc cartridges 1 and 6. When recording and reproducing the 8 cm DVD cartridge 6, a selective operation that does not cause the shutter opener 67 for 8 cm DVD to retract is enabled by a simple mechanism. 8cm DVD shutter opener 57, 1
The 2 cm DVD shutter opener 51 has a function of holding the shutters of the disk cartridges 1 and 6 in an open state during recording and reproduction.
2 cannot be kept open. Therefore, when recording and reproducing the 8 cm DVD cartridge 6 as described above,
A mechanism for preventing the 8 cm DVD shutter opener 57 from retreating (not separating from the cartridge) enables a smooth recording / reproducing operation.

A description will be given in relation to the third aspect of the present invention.
As described above, the mounting height of the 8 cm DVD cartridge 6 on the disk tray 11 is lower than the mounting height of the 12 cm disk 3. As a result, the 8 cm DVD shutter opener 57 can be installed at a position lower than the 12 cm disk 3 placed on the disk tray 11. In a plan view, the four corners of the 8 cm DVD cartridge 6 are located outside the outer diameter of the 12 cm disk 3, but the shutter 12 is located inside the 12 cm disk 3. The 8 cm DVD shutter opener 57 overlaps the 12 cm disc 3 in a planar manner. The shutter opener 57 for 8 cm DVD is installed at substantially the same height as the 12 cm disk 3, and in the transport operation when the 12 cm disk 3 is placed, the 8 cm DVD is opened at the end face of the 12 cm disk 3.
It is conceivable that the shutter opener 57 is pushed in and retracted.
An accident in which the DVD shutter opener 57 is pushed out from the 12 cm disk mounting portion 18 of the disk tray 11 by the spring force urged easily occurs. To prevent such a problem from occurring, the height of the 8 cm DVD cartridge 6 placed on the disc tray 11 is set lower than the height of the 12 cm disc 3, and then the 8 cm DVD shutter opener 57 is placed on the disc tray 11. 12 in the state
By placing the disc tray 11 at a position lower than the cm disc 3, a mechanism in which the 8 cm DVD shutter opener 57 does not interfere with the 12 cm disc 3 in the transport operation of the disc tray 11 was achieved. Therefore, 8 cmD during the transfer operation
The VD shutter opener 57 does not damage the 12 cm disc 3 and the light 12 cm disc 3
There is no pushing out of the 2 cm disk mounting portion 18.

The 8 cm DVD cartridge mounting section 2
Another effect of lowering 1 is that the 8 cm DVD cartridge 6
The positioning pins 43 and 44 can be set on the 8 cm DVD cartridge mounting portion 21 without interfering with the 12 cm disk 3. The tip height of the positioning pins 43 and 44 is 12 cm placed on the 12 cm disc loading portion 18.
It is lower than the lower surface of the disk 3 and does not interfere. By setting the positioning pins 43 and 44, when the user sets the 8 cm DVD cartridge 6 on the 8 cm DVD cartridge mounting portion 21, it can be set only in the direction matching the positioning pins 43 and 44, and the 8 cm DVD cartridge 6 is set. There is no mistake of direction, front and back and front and back.

A description will be given in connection with the fourth aspect of the present invention.
Positioning hole 1 for 12 cm DVD cartridge 1 in 12 cm DVD cartridge mounting portion 20 of disc tray 11
Positioning pins 41 and 42 to be fitted to 4 and 15 are provided. Similarly, the 8 cm DVD cartridge
Positioning pins 43 and 44 that fit into the positioning holes 16 and 17 of the cmDVD cartridge 6 are provided. As described above in connection with the third aspect of the present invention, the user can use the 12 cm DVD cartridges 1, 8
When setting either of the cmDVD cartridges 6, the direction is not mistaken. In addition, both mounting portions 20,
Since the positioning pins 41, 42, 43, and 43 are provided on both of the disc cartridges 21, the same setting procedure can be performed for both of the two types of disc cartridges 1 and 6, which also contributes to improved operability for the user. Also, 12 cm DVD cartridges 1, 8
Since both of the cm DVD cartridges 6 are accurately positioned with respect to the disk recording / reproducing device,
The DVD shutter opener 51 and the 8 cm DVD shutter opener 57 can accurately access the shutters 10 and 12 of both disk cartridges 1 and 6, thereby improving the operation reliability.

A description will be given in connection with the fifth aspect of the present invention.
As described above, when playing the 8 cm DVD cartridge 6, the position of the recording / reproducing mechanism unit 25 is different from that of other media,
cm DVD cartridge 1, 12cm disc 3 alone,
Unlike the position where the 8cm disc 4 alone is played, it is low.
With this configuration, the 8 cm DVD cartridge 6 can be played while being placed on the disc tray 11, enabling a simple mechanism and simple operation, improving operation reliability, and reducing mechanism cost. Recording / playback mechanism 2
In order to adopt a configuration in which the recording / reproducing position of No. 5 is common, after loading the 8 cm DVD cartridge into the case, 1
It is necessary to raise the playing height of the 2 cm DVD cartridge to adjust the height. Actually, the periphery of the positioning pin for holding and placing the 8 cm DVD cartridge is separated from the structure of the above-described embodiment, which is integrated with the disk tray, and is constituted by a separate part, so that it can be moved up and down. If such a configuration is adopted, the number of components must be increased due to separate components, and the complexity and the number of components need to be increased by separately adding a positioning pin elevating mechanism, and the disk recording / reproducing apparatus becomes complicated and the cost increases. Also, a complicated configuration is not desirable in terms of aesthetics of the disc tray. In addition, when the positioning pin rises, a 12cm disk or 12c
8c to avoid interference with the mDVD cartridge
Since it is necessary to selectively lift the 8 cm DVD cartridge by detecting the mounting of the mDVD cartridge, it is necessary to add a detection mechanism of the mounted state of the 8 cm DVD cartridge and a selective positioning pin raising operation mechanism,
When the selective operation is required, it is difficult to configure the mechanism by the continuous operation using one drive motor as described above, and it is necessary to separately increase the motor for driving the selective positioning pin raising operation mechanism. . Therefore, the cost increases due to an increase in the number of motors. Also, when playing, 8cmD
Since the shutter opener for VD needs to be engaged with the shutter of the 8 cm DVD cartridge to maintain the open state of the shutter, the shutter opener for 8 cm DVD is 8c.
The necessity of raising the mDVD cartridge while engaging and following the raising of the mDVD cartridge also complicates the mechanism as compared with the configuration of the above-described embodiment.

On the other hand, according to the present invention, 8 cmD
Recording / reproducing mechanism section 25 when playing VD cartridge 6
Is changed to a position for recording and reproducing other media, a 12 cm DVD cartridge 1, a 12 cm disc 3 alone, and an 8 cm disc 4 alone, and the disc tray 11 is lowered.
In this configuration, the recording and reproduction are performed while being held in the state of being placed on the medium, so that a mechanism of continuous operation by one drive motor 34 can cope with four types of media, and a simple operation with high reliability and cost. It is possible to realize a simple mechanism.

A description will be given in connection with the sixth aspect of the present invention.
As described above, the basic operation of the disc recording / reproducing apparatus is the same in any of the four types of media, the 8 cm DVD cartridge 6, the 12 cm DVD cartridge 1, the 12 cm disc 3 alone, and the 8 cm disc 4 alone. First, “loading operation”, “7 mm raising operation of recording / reproducing mechanism unit 25 (second recording / reproducing position) and lowering operation of clamper holder 86”, and then “raising of recording / reproducing mechanism unit 25 to the first recording / reproducing position”. Operation and Upward Operation of Clamper Holder 86 by Predetermined Amount "in this order. In the case of the 8 cm DVD cartridge 6, the “loading operation” and the “7 mm
The two states of the ascending operation (second recording / reproducing position) and the lowering operation of the clamper holder 86 make the recording / reproducing mechanism possible, but the basic operation order does not change. In the case of other media, "the ascending operation of the recording / reproducing mechanism unit 25 to the first recording / reproducing position and the ascending operation of the clamper holder 86 by a predetermined amount" are continuously performed, and a recording / reproducing mechanism state is established. As described above, since the basic mechanism operation order is configured in common, the continuous operation mechanism by the single drive motor 34, the “load operation”, and the “recording / reproducing mechanism 25 7 mm raising operation (second recording / reproducing position) and lowering operation of the clamper holder 86 ", and" the raising operation of the recording / reproducing mechanism unit 25 to the first recording / reproducing position and the raising operation of the clamper holder 86 by a predetermined amount "in this order. This makes it possible to provide a mechanism for performing the above-described reverse operation by rotating counterclockwise.
Regardless of a device capable of playing a total of four types, that is, two types of cartridges and two types of single disks having different shapes, the drive motors of the media transport mechanism are integrated into a single drive motor 34, and the operation is simple, highly reliable, and cost effective. It has become brainy to make it a strange mechanism.

A description will be given in connection with the seventh aspect of the present invention.
As described above, the clamper holder 86 on which the disk clamper 30 is mounted moves the recording / reproducing mechanism 25 to a position corresponding to the second recording / reproducing position in which the recording / reproducing mechanism 25 is raised to a position corresponding to the 8 cm DVD cartridge 6. 12c
The first recording / reproducing position raised to a position corresponding to the mDVD cartridge 1 and the uppermost position retracted so as not to interfere in the carrying-in operation are movable. With this configuration, the 12 cm disc 2 in the 12 cm DVD cartridge 1 can be held at the first recording / reproducing position so as to be recordable / reproducible, and the 8 cm disc 7 in the 8 cm DVD cartridge 6 can be held at the second position so as to be recordable / reproducible. The common disk clamper 30 enables recording and reproduction of two types of cartridges and two types of single disks. With this mechanism configuration, 8cmD
It is possible to set the recording / reproducing height position of the VD cartridge 6 and the 12 cm DVD cartridge 1 at a height position corresponding to the height of each of the mounting portions 20 and 21 of the disc tray 11, respectively, thereby enabling recording / reproducing of two types of cartridges. Can be realized by a single disk recording / reproducing apparatus, and the mechanism can be operated with high operation reliability and at low cost by using a simple mechanism as described above.

A description will be given in connection with the eighth aspect of the present invention.
As described in connection with the invention of claim 7,
Clamper holder 86 equipped with disc clamper 30
Means that the recording / reproducing mechanism unit 25 is
, The position corresponding to the second recording / reproducing position raised to the position corresponding to, the first recording / reproducing position where the recording / reproducing mechanism 25 is raised to the position corresponding to the 12 cm DVD cartridge 1, and no interference in the loading operation. It is configured to be able to move at three positions of the uppermost position retreated. Convex portions 91, 92, 93, 94 of clamper holder 86
Is a portion for pressing the upper surface of the 12 cm DVD cartridge 1, and the convex portions 106, 107, 108, and 109 are 8c
A portion for pressing the upper surface of the mDVD cartridge 6. The clamper holder 86 includes first and second arm members 87 and 88.
12c with the pressing force specified by the spring 95 between
The upper surface of the mDVD cartridge 1 or the upper surface of the 8 cm DVD cartridge 6 is pressed and held to prevent a situation in which the rotation of the disk inside the disk cartridge is hindered by unnecessary movement of the cartridge during recording and reproduction. With this configuration, the 12 cm DVD cartridge 1 can be held at the first recording / reproducing position, and the 8 cm DVD cartridge 6 can be held at the second position. With the common clamper holder 86, 2
Can hold various kinds of disk cartridges 1 and 6. By providing this mechanism configuration, the 8 cm DVD cartridge 6
And the 12 cm DVD cartridge 1 can be set to the height position corresponding to the height of each of the mounting portions 20 and 21 of the disk tray 11, respectively, and the recording of the two types of disk cartridges 1 and 6 can be performed. While a single disk recording / reproducing apparatus can perform reproduction, a simple mechanism as described above can provide a mechanism with high operation reliability and low cost.

A description will be given in connection with the ninth aspect of the present invention.
As described above, in the loading operation in which the 12 cm DVD cartridge 1 is placed, first, the recording / reproducing mechanism 25
When the recording / reproducing position is raised, the clamper holder 86 descends and presses the upper surface of the 12 cm DVD cartridge 1. At this time, the first and second arm members 87 and 88
Since it is lowered to the position corresponding to the cm DVD cartridge 6, the 12 cm DVD cartridge 1
And the upper surface of the 8 cm DVD cartridge 6 are absorbed by the extension of the spring 95. Since the clamper holder 86 is configured to be operable in this manner, the basic operation of the mechanism “loading operation” and the “movement of the recording / reproducing mechanism unit 25 by 7 mm (second operation) as in the description related to the seventh aspect of the invention. And the lowering operation of the clamper holder 86 "and" the raising operation of the recording / reproducing mechanism 25 to the first recording / reproducing position and the raising operation of the clamper holder 86 by a predetermined amount "are common to the two types of cartridges. And can be executed sequentially. Since the basic mechanism operation sequence is configured in common, a single drive motor 34 can form a continuous operation mechanism, and drives the drive motor of the media transport mechanism regardless of the device capable of recording and reproducing a total of four types of media. A simple, high-reliability, and low-cost mechanism integrated into one motor 34 was achieved.

Further, the recording / reproducing mechanism 25 rises and the second

The mechanism for absorbing the positional difference of the clamper holder 86 by the spring 95 is a mechanism for detecting which of the 12 cm DVD cartridge 1 and the 8 cm DVD cartridge 6 is placed on the disk tray 11 (a detection switch). This is often easier than installing a mechanism (having a dedicated driving force) for selectively changing the descent position of the clamper holder 86 according to the detection information, and the number of parts is small and the cost is low.

A description will be given in connection with the tenth aspect of the present invention. As described above, when the 12 cm DVD cartridge 1 is placed, it is held by the clamper holder 86 at the first recording / reproducing position. The pressing load at this time is defined by the spring 95. Similarly, when the 8 cm DVD cartridge 6 is placed, it is held by the clamper holder 86 at the second recording / reproducing position. The pressing load at this time is also defined by the spring 95. When the clamper holder 86 is at the uppermost retracted position, the tips 119 of the first and second arm members 87 and 88 are connected to the lower end 1 of the clamper holder 86.

Thereby, the pressing force can be made substantially constant, and the recording / reproducing operation is hindered by the lifting of the disk cartridges 1 and 6 due to insufficient pressing force, and the recording / reproducing operation is hindered due to deformation of the disk cartridges 1 and 6 due to excessive pressing force. It is possible to prevent a situation in which the mechanism cannot be operated due to insufficient motor power due to excessive pressing force. After the spring 95 has a function of regulating the pressing force, as described above, the position of the clamper holder 86 at the second recording / reproducing position is different, and the position of the 12 cm DVD cartridge 1 when placed on the disc tray 11 is changed. By providing a function to absorb the difference in distance between pressing the upper part and the upper surface of the 8 cm DVD cartridge 6 by stretching, the number of parts can be reduced without installing a spring for each function. Cost can be reduced.

A description will be given in relation to the eleventh aspect of the present invention. When the user attaches and detaches the 12 cm DVD cartridge 1 to and from the disc tray 11, the disc tray 11 has both sides from the upper surface of the placed 12 cm DVD cartridge 1 in order to facilitate holding the side edge of the 12 cm DVD cartridge 1. A release portion 132 which is low and is opened to expose a part of the side edge of the 12 cm DVD cartridge 1 is formed. Thereby, 12 cmD
