DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a recording and/or reproducing apparatus using cartridges within which recording media are accommodated, and more particularly to a recording and/or reproducing apparatus provided with a loading mechanism adapted for selectively taking out one cartridge from an accommodating body within which a plurality of cartridges are accommodated to allow the cartridge thus taken out to undergo loading into a recording and/or reproduction unit provided within the apparatus.
BACKGROUND ART
Hitherto, there have been used recording and/or reproducing apparatuses adapted for accommodating in advance, within an accommodating body, plural disc cartridges within which there are respectively accommodated discs such as optical disc, etc. which are a recording medium on which information signals are recorded to selectively take out a desired disc cartridge from the accommodating body to allow it to undergo loading into the recording and/or reproduction unit to permit continuous recording and/or reproduction of information signals.
As the recording and/or reproducing apparatus of this kind, there are recording and/or reproducing apparatuses adapted for allowing an accommodating body within which plural disc cartridges are accommodated in a multi-step manner so that their principal surfaces are in parallel to each other to undergo movement operation in a direction perpendicular to the principal surface of the accommodated disc cartridges by using a movement operation mechanism to thereby allow any one of the disc cartridges accommodated within the accommodating body to be located at the position caused to correspond to the recording and/or reproduction unit to take out the disc cartridge which has been moved to the position corresponding to the recording and/or reproduction unit toward the outward of the accommodating body by using the movement operation mechanism to allow it to undergo loading into the recording and/or reproduction unit.
The disc cartridge which has been selectively taken out from the accommodating body and has been loaded into the recording and/or reproduction unit is caused to undergo recording and/or reproduction of information signals with respect to the disc accommodated therewithin, and is then accommodated into the accommodating body through the taking-out mechanism for a second time.
The recording and/or reproducing apparatuses of this kind conventionally used are provided with a movement operation mechanism in which there are provided movement operation members for allowing disc cartridges to undergo movement operation every accommodating portions within which respective disc cartridges are accommodated within the accommodating body. This movement operation mechanism allow the movement operation member to be engaged with the disc cartridge accommodated within the accommodating body to allow it to undergo movement operation extending over the inside and the outside of the accommodating body to thereby take out the disc cartridge from the accommodating body to allow it to undergo loading into the recording and/or reproduction unit, or to allow the disc cartridge loaded in the recording and/or reproduction unit to be accommodated into the accommodating portion constituted within the accommodating body for a second time.
Since the recording and/or reproducing apparatuses conventionally used are of a structure in which movement operation members are disposed every accommodating portions within which plural disc cartridges are respectively accommodated, the accommodating body is caused to be large-sized. As a result, the recording and/or reproducing apparatus itself in which the accommodating body is disposed would be also large-sized.
In addition, since the movement operation members caused to undergo movement operation extending over the inside and the outside of the accommodating body every accommodating portions are disposed, it is necessary to provide, every accommodating portions, opening portions adapted so that movement operation members are inserted there
