The present invention provides a cartridge carrying system for performing carriage control so as to enable carriage of a cartridge even when a gap is made between arms and the cartridge. In particular, the cartridge carrying system includes: a cartridge holding mechanism having two arms, the cartridge holding mechanism grabbing a cartridge stored in a first predetermined position at one end of each of the two arms by turning the two arms around respective supporting points in directions opposed to each other; an arm turning mechanisms; a carrying mechanism for carrying the cartridge in such a manner that the cartridge is drawn into or from a space between the two arms; a carriage driving mechanism for driving the carrying mechanism; and a carriage completion monitoring mechanism for monitoring if the cartridge is carried to a second predetermined position, and the cartridge carrying system controlling so that the operation for carrying the cartridge to the second predetermined position is continued, when it is detected that the cartridge is not carried to the second predetermined position within a given time.
