Recording and/or reproducing apparatus with disc stocker and transport

A recording and/or reproducing device comprising:

• a disc stocker for holding a plurality of disc cartridges in tiers, each said disc cartridge being comprised of a recording disc housed within a cartridge main member, said disc stocker holding said disc cartridges so that each disc cartridge is partially exposed to outside;
• and
• transport means for selecting one of the disc cartridges held by said disc stocker and transporting the selected disc cartridge to a recording and/or reproducing unit, said transport means is responsive to a portion exposed to outside the disc stocker of one of the disc cartridges held by said disc stocker being thrust towards the inside of the disc stocker to initiate the operation of selecting said one of the disc cartridges and transporting the selected disc cartridge to said recording and/or reproducing unit, wherein said transport means includes:
• a movably supported movement member,
• an endless driving belt having a portion lying along a path of movement of said movement member, said endless belt being placed around a driving pulley member and fed by said driving pulley member,
• a follower pulley member arranged on said movement member and carrying the endless driving belt placed therearound,
• a profiling member movably mounted on said movement member and moved by rotation of said follower pulley member, and
• a cam member arranged along a path of movement of said movement member for limiting movement of said profiling member relative to said movement member,
• a driving force transmitted by said endless driving belt acting in dependence upon the position of said movement member relative to said cam member so that said driving force rotates said follower pulley member to cause movement of said profiling member relative to said movement member when said cam member enables movement of the profiling member relative to the movement member, said driving force moving said movement member when said cam member inhibits movement of the profiling member relative to the movement member.
