Classification: CPC B | IPC B

Claim 11:
12. A printing device, comprising:
a position determination component configured to determine a printing position of printing information that is printed using thermochromic ink on an object to be printed conveyed by a conveyance machine;
an erasing component including a heat source, configured to erase the printing information that is printed using the thermochromic ink on the printing position by emitting heat from the heat source, a height position of which is adjusted according to the printing position, from a direction perpendicular to a conveyance direction of the object to be printed by the conveyance machine, according to a timing at which the printing position, determined based on the printing position, passes;
a printing component using the thermochromic ink, disposed behind the heat source of the erasing component along the conveyance direction, configured to print information on the object to be printed from the direction perpendicular to the conveyance direction, a height position of which is adjusted according to the printing position, according to the timing at which the printing position, determined based on the printing position, passes, wherein the position determination component includes
a size measurement sensor configured to measure a height and width of the object to be printed being conveyed by the conveyance machine, and
a calculation component configured to calculate the printing position based on the height and width of the object to be printed.
