The utility model discloses
code writing and reading equipment, and belongs to the technical field of printing. The
code writing and reading device comprises a device body and a
code writing and reading
assembly, the device body is provided with a fixing groove, and the fixing groove is used for at least part of the printing supplies to be inserted. The code writing and reading
assembly is arranged on the equipment body, under the condition that at least part of the printing supplies are inserted into the fixing groove, the groove wall of the fixing groove is matched with the printing supplies in a limiting mode in the first direction, chips of the printing supplies are electrically connected with the code writing and reading
assembly, and the first direction is perpendicular to the
insertion direction of the printing supplies and the width direction of the printing supplies. According to the scheme, the code writing and reading assembly can be in good contact with the
chip of the printing
consumables so as to guarantee the stability of
data transmission, meanwhile, the two hands of an operator can be liberated, the code writing and reading assembly of the code writing and reading equipment is not prone to being interfered by external factors and disconnected from the
chip, then the stability and integrity of
data transmission can be guaranteed, and the
data transmission efficiency is improved. Therefore, the success rate of data upgrading and updating is improved.
