ABSTRACT:
The optical recording medium protection cassette of the present invention comprises a housing, a clasping member and at least one switch member. A first opening for retaining an optical recording medium is formed on a first lateral side of the housing and a groove is formed on the inside of a second lateral side which is perpendicular to the first lateral side. The clasping member is in engagement with the first opening of the housing to restrict the optical recording medium to be located within the housing. The clasping member is provided with at least a first buckling portion and at least a V-shaped portion having a first side and a second side. Each switch member has a first end as a second buckling portion fastened to the first buckling portion of the clasping member, which makes the switch member rotate relative to the first buckling portion, and a second end which is a positioning portion substantially stops at either the first side or the second side of the V-shaped portion.Furthermore, a clip member is formed at the clasping member, which has a protruding portion to fasten the groove disposed at the inside of the second lateral side of the housing so as to secure the clasping member within the housing, and an annular portion, the protruding portion of the clip member being disengaged from the groove such that the clasping member can be withdrawn from the housing by switching the annular portion.
