DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a disc cartridge container for containing and holding a matrix array of a plurality of disc cartridges each housing a disc on which information signals such as music signals are recorded or are to be recorded, and to a disc recording and/or reproducing apparatus for selecting one of the plural disc cartridges contained and held within the disc cartridge container and recording/reproducing the information signals on or from the disc contained in the selected disc cartridge, or sequentially recording/reproducing the information signals on or from the discs contained in the disc cartridges.
BACKGROUND ART
There has hitherto been employed a disc recording and/or reproducing apparatus having a disc exchange function of selecting one of disc cartridges previously stored in a disc container and of reproducing information signals, such as music signals, recorded on a disc contained in each disc cartridge, or recording information signals on the disc.
With such disc recording and/or reproducing apparatus, the disc cartridges are contained in the cartridge container so that the major surfaces of the disc contained in the disc cartridges face each other, that is, plural disc cartridges in the form of thin plates are stacked vertically.
By stacking the disc cartridges and containing them in this state in the cartridge container, plural disc cartridges may be efficiently contained in a smaller space.
However, for recording and/or replay of the information signals, it becomes necessary to provide a disc exchange mechanism for pulling out the disc cartridge from the cartridge container and transferring the disc cartridge to a disc recording and/or reproducing section for loading thereon. Besides, with a disc recording and/or reproducing apparatus, having such disc exchange function, it is necessary to provide a mechanism whereby the disc cartridge pulled out from the cartridge container may be loaded on a disc driving unit provided with a disc rotation driving mechanism and/or information signal recording and/or reproducing means. The result is the increased size and complicated mechanism of the disc recording and/or reproducing apparatus.
On the other hand, with the disc container having cartridge container sections for holding plural disc cartridges in a stacked state, it is not possible to check the indication of the recording contents of the disc contained in the disc cartridge on a label affixed on the surface of the disc cartridge.
Besides, with the cartridge container containing plural disc cartridges in a stacked state, since the cartridge inserting/detachment opening having a width corresponding to the thickness of the disc cartridge is arrayed so as to be sequentially stacked in one plane, it becomes extremely difficult to introduce or detach the disc cartridges. That is, it becomes extremely difficult to have the desired disc cartridges contained correctly in the pre-set cartridge container.
It is therefore an object of the present invention to provide a disc cartridge container in which plural disc cartridges may be arrayed so that the major surfaces of the discs contained in the cartridge main members are in one and the same plane so that the plural disc cartridges may be correctly contained without stacking vertically.
It is another object of the present invention to provide a disc cartridge container in which indication means for indicating the recorded contents or the like provided on the surface of the disc cartridge may be seen through from outside.
It is a further object of the present invention to provide a disc cartridge container in which a shutter member provided on the disc cartridge is adapted to be opened and closed after the disc cartridge is contained in a cartridge container for assuring positive protection of the disc contained in the disc cartridge.
It is a further object of the present invention to provide a disc cartridge container and a recording and/or reproducing apparatus employing such disc cartridge container, in which the shutter member
