A transfer unit configured to transfer a motion vector of a co-located macroblock corresponding to a w-th macroblock from an external memory to a buffer when a determining unit determines that the motion vector of the co-located macroblock corresponding to the w-th macroblock is necessary for calculating the motion vector for the w-th macroblock. In one embodiment, the anchor includes an anchoring portion and a receiving portion. When the ink sheet cartridge is accommodated to a facsimile device, a thermal head and a platen are positioned at the central open space. This third chamber is designed such that it is in contact with the sole of the foot.
