PURPOSE: To make a device small-sized and simple and shorten the carrying time by arranging a cartridge storage part and an information recording and reproducing part on the outside of the range, where a cartridge carrying mechanism part is rotated around a spline shaft, radially in parallel with the spline shaft.

CONSTITUTION: Cartridge storage parts 4 where cartridges 1 are stored and an information recording and reproducing part 5 where the cartridge 1 is set to read or write information are arranged radially apart from one another on the outside of the range, where a cartridge carrying mechanism part 6 is rotated around a ball spline shaft 7, in parallel with the spline shaft 7. The cartridge carrying mechanism is guided uniaxially and cartridge storage parts and the information recording and reproducing part are arranged radially around the cartridge carrying mechanism, thereby simplifying the structure and shortening the time required for carrying.
