摘要

PROBLEM TO BE SOLVED: To provide an optical disc master storage device which is capable of isolating an optical disc from dusts in air and fixing it for preventing abrasions and also saves space with a nonslip part. SOLUTION: The optical disc master storage device stores at least one optical disc master and comprises an upper lid 102 which is provided with a first partitioning protruding ridge 104a, along the inner peripheral edge and a lower lid 110 which connect with the upper lid 102 to form a storage space to store at least one optical disc master. The lower lid 110 has a plurality of second partitioning protruding ridges 104b along the inner periphery and forms recessed- grooves. The first partitioning protruding ridge 104a is positioned in the recessed-groove which is formed by the plurality of the second partitioning protruding ridges 104b when the upper lid 102 and the lower lid 110 are closed. The lower lid 110 is further provided with a plurality of inner peripheral protruding portions 112 and a plurality of outer peripheral protruding portions 114 which are arranged in a circular shape at the surface of the inner side. At least one optical disc master is placed between the plurality of the inner peripheral protruded pieces 112 and the outer peripheral protruded pieces 114.
