Cartridge accommodation case

Abstract

A cartridge accommodation case includes a generally rectangular cartridge accommodation top case formed with partitioned rooms for holding plural cartridges and a generally rectangular cartridge accommodation bottom case having partitioned rooms which have substantially the same shape as and opposed to the partitioned rooms of the top case. The top case and the bottom case have the same structure and are provided with projections and recesses which can engage each other. The cartridge accommodation case is given, inside, partitioned rooms which are two times larger in space than the partitioned rooms of the top case and the bottom case when the top case and the bottom case are placed one on the other and the projections and the recesses are engaged with each other. The top case and the bottom case are provided with ribs which are fitted into/with each other when cartridge accommodation cases are stacked.
