Disk storage medium processing apparatus

A disk storage medium processing apparatus comprising:

• at least an apparatus body having a disk loading/unloading slot;
• a traverse unit which is disposed in said apparatus body to conduct at least one of recording, deletion, and reproduction of information onto or from a disk;
• and
• a disk conveying means which conveys said disk into said apparatus body when a part of said disk is inserted through said disk loading/unloading slot and which ejects a part of said disk through said disk loading/unloading slot from a state that said disk is housed in said apparatus body, wherein said disk conveying means comprises at least a pair of first and second disk conveying arms which are pivotably attached to the apparatus body and which can hold the periphery of said disk to convey said disk;
• wherein said first and second disk conveying arms are adapted to hold a periphery of said disk to convey said disk to said traverse unit when a part of said disk is inserted through said disk loading/unloading slot and are adapted to hold the periphery of said disk to convey said disk from said traverse unit to eject a part of said disk through said disk loading/unloading slot,
• wherein said first disk conveying arm is provided with a disk driving roller which can hold the periphery of said disk and rotate in directions of withdrawing said disk and of ejecting said disk, and said second disk conveying arm is provided with a disk guide portion which is made of friction material and which can hold the periphery of said disk,
• wherein said first disk conveying arm is always biased in such a direction that said disk driving roller comes closer to said disk guide portion of said second disk conveying arm and said second disk conveying arm is always biased in such a direction that said disk guide portion comes closer to said disk driving roller, and
• wherein the biasing force biasing said first disk conveying arm is set to be more than the biasing force biasing said second disk conveying arm.
