Description of the Invention [Technical Field] The present invention relates to a technique for retrieving a reproducing device for a disc drive, particularly a DJ (Disc Jockey). [Prior Art] There is a reproduction device used by a music player (DiscJockey 0: hereinafter referred to as DJ) that provides music in the club. DJ and others use a regenerative device to perform a unique performance using a song that is stored on a CD (Compact Disc). A conventional technique of a regenerative device used in the case of a DJ or the like is disclosed in, for example, Japanese Laid-Open Patent Publication No. 2004-303295. Conventionally, a sound source used by a DJ or the like is a CD, and the above-described reproducing device may have a CD drive to reproduce a CD. In recent years, audio sources have not been limited to CDs, and the memory of HD (Hard Disc) drives that can store a large number of music files has become popular. Therefore, 〇 in DJ, etc. is required to use HD's regenerative device. In order to meet such market requirements, a regenerative device having both an HD drive and a CD drive has been developed and marketed. As a conventional technique including a playback device for both the HD drive and the CD drive, for example, "User's Manual (HDX)" Numark Industries LLC, [Online], [Search on January 30, 2008], and URL (URL: http: //www.numark.jp/ pdf/manuals/HDX_Manual_JP.pdf)』. This HD drive is a removable structure. 200937396 SUMMARY OF THE INVENTION The above-described regenerative device including both the CD drive and the HD drive has the following problems. First of all, there are not many DJs that use the data of both CDs and HDs at the same time, and most of them are one of them. For example, such a reproduction device is often used as a single player, and the DJ system is composed of two single players and one mixer Ο. In this case, the built-in media of each player is selected in accordance with the requirements of the DJ or the like, and the built-in HD drive, the built-in CD drive, or the external medium is selected in time to constitute the system. Therefore, in a general DJ system, it is sufficient that the reproducing apparatus has either an HD drive or a CD drive. However, although the HD device can be removed from the above-described reproducing device, since it is distributed in a state in which both drivers are provided, this portion is costly and causes a high price. Further, from the viewpoint of operability, the DJ space is required to have a certain degree of breadth, and the above-described regenerative device having various types of drivers increases the size of the device and occupies a DJ space, resulting in a deterioration in the feeling of use. In addition, DJs and the like usually carry the reproduction device to the club for performance, but the load on the 2 drive becomes heavy. In the case of using only the CD drive, the DJ can remove the HD drive, but the CD drive cannot be removed when only the HD drive is used. Moreover, when the HD drive is removed, it is necessary to temporarily remove the center shaft, the magnetic disk, the record, and the record cover from the main body. These operations are not only very troublesome, -6 - 200937396 In general, DJ, etc., is a subtle adjustment of the degree of engagement of the record cover (the degree of sliding of the record), and is therefore an uninteresting work for DJs and the like. Further, in order to perform the attachment and detachment of the center axis of the rotation center, the rotation shaft may be disengaged due to the work, which may cause a failure. The present invention has been developed to solve the above problems of the prior art, and an object of the present invention is to provide a general-purpose disc drive holder and a disc that can be mounted on different disc drivers, particularly for DJs and the like. Tablet regeneration device. In order to achieve the above object, in the present invention, the disc drive holder includes a first connector substrate having a first connector connected to the first disc drive, and a second disc drive connected to the second disc drive. The second connector and the third connector connectable to the first connector are detachably attached to the second connector substrate of the first connector substrate. In the disc drive holder of the above configuration, the disc drive holder may be such that when the first disc drive is mounted, the second connector substrate is removed from the first connector substrate. In the disc drive holder of the above-described configuration, the disc drive holder may be configured such that when the second disc drive is mounted, the third connector is connected to the first connector. The second connector substrate is mounted on the first connector substrate. In the disc drive holder of the above configuration, the second connector substrate may be provided with a circuit for converting the signal input to the second connector to be input to the first connector.

FIG. 4 shows a case where the HD drive 24 is mounted. As shown in Fig. 4, the disc drive holder 10, the flat plate 44, and the front panel 46 are screwed to the slots 42 of the body 31. Further, in the case where the CD drive 26 ® is mounted, the CD may be replaced with the flat plate 44 having the opening for reading/non-reading and the front panel 46. In order to switch the driver used by the DJ or the like, it is easy to remove the disc drive holder 10 from the main body 31 and remove the second connector substrate 20 provided in the disc drive holder 10. For example, in the case where it is desired to switch from the HD drive 24 to the CD drive 26, the DJ or the like uses a driver, removes the front panel 46 and the flat plate 44' and then removes the disc drive holder 1''. Next, the HD driver 24 is removed from the disc drive holder 10, and the second connector board 2 is mounted, and then the CD driver 26 is mounted. Then, the disc drive holder 10 is returned to the main body 31 as it is -12-200937396. In this operation, in particular, it is not necessary to remove the magnetic disk 34 or the like provided on the upper surface of the body 31. Therefore, the operation of the rotating mechanism is not required, and the absence of the attracting rotating mechanism can be substantially avoided. Further, 'the degree of fixation of the adapter 40 adjusted by the DJ or the like is maintained, and the operational feeling is maintained'. As described above, the disc drive holder 1 of the present embodiment is provided with the HD driver 24 in addition to the 0. The second connector substrate 20 is detachably connected to the CD driver 26 and is detachably attached to the first connector board 18. Therefore, the DJ or the like can use only the disc drive required by itself in the disc reproducing device 30. Moreover, the replacement of the drive is very easy, and it does not cause a malfunction of the mechanism. Moreover, by having only one disc drive, the configuration of the disc reproducing device 30 becomes more space-saving and the weight can be reduced. In this way, it is possible to ensure a wider DJ space for DJs and the like, and it is easy to carry and the like, and it is possible to improve usability. 〇 The manufacturer sells the disc drive device 30 having the disc drive holder 10, for example, in the state without the disc drive, and the DJ or the like prepares the disc drive to be used. Therefore, the disc reproducing device 30 can be made lower in cost and lower in price. The above embodiment is merely an example, and various changes and modifications can be made within the scope of the invention. For example, in the above embodiment, the case where the CD driver 26 and the HD driver 24 are mounted has been described as an example. However, in the case where the second connector board 18 and the second connector board 20 are provided with an appropriate connector and the processing power-13-200937396, and any other disc driver is mounted, the present invention can be applied. In the embodiment, the device for reproducing the sound effect signal is taken as an example, but it is also applicable to the device for reproducing the signal including the image signal.
