PROBLEM TO BE SOLVED: To smoothly execute the carrying in and out of a base while smoothly holding a base without deflecting a central part downward, by forming the dent parts recessed downward from a peripheral edge supporting part, on the loading shelves laterally installed at intervals throughout a number of stages and providing a central supporting part in the center of the dent parts. SOLUTION: Plural stages of loading shelves 2 are laterally installed inside of a cassette body 1. The dent part 4 is formed on a center of the loading shelf 2, in connection with a peripheral edge supporting part 3 formed on a side face peripheral edge of the loading shelf 2. The dent part 4 is provided with a center supporting part 5 positioned on the center of the loading shelf 2, and projecting upward so that the height of the same becomes equal to the peripheral edge supporting part 3. A base 6 is loaded on the loading shelf 2, a peripheral edge of the base 6 is supported by the peripheral edge supporting part 3 of the loading shelf 2, and a central part of the same is supported by the center supporting part 5. The base 6 and the loading shelf 2 form a gap 7 at the part of the dent part 4 formed on the loading shelf 2. |
