ABSTRACT:
The technique of the invention relieves the requirement of repeated positioning to a wireless communicable range in the process of data transmission to and from each of multiple cartridges by wireless communication.A carriage210with multiple ink cartridges111through116mounted thereon is stopped at a position P1,which is away a distance D0from an antenna233and is conveyed from the position P1at a preset velocity V. With the movement of the carriage210,detection storage modules121through126mounted on the ink cartridges111through116sequentially approach to the antenna233and establish communication with a control circuit222of a printer via the antenna233of a receiver transmitter unit230.This arrangement enables data transmission between the control circuit222and each of the detection storage modules121through126without repeatedly stopping the carriage210.
