ABSTRACT:
A carriage (recording head portion) which an ink cartridge including a non-volatile memory is to be mounted has a memory access controlling portion for controlling accesses to a non-volatile memory, thereby reducing the number of connection lines between the carriage (recording head portion) and a printer main body controlling portion.The apparatus main body controlling portion and the memory access controlling portion transmit and receive data therebetween by means of serial data communication. The memory access controlling portion reads out various information (the amount of remaining ink, use start year and month, and the like) stored in each non-volatile memory and then stores the readout information in a RAM in the memory access controlling portion. The apparatus main body controlling portion issues an access request command for the RAM to read information out from the RAM and update the readout information. When a printer is powered off, the apparatus main body controlling portion issues a write back command. The memory access controlling portion writes the information in the RAM back to the non-volatile memory.
