Non-contact communication between device and cartridge containing consumable component
First Claim
1. A device for receiving at least one cartridge for containing a consumable component, the device comprising:
- a cartridge holder that mounts at least one said cartridge containing the consumable component; and
a transmitter/receiver for non-contact communication with the cartridge while proximate to the cartridge, wherein the cartridge has a memory circuit including an antenna for non-contact communication with the transmitter/receiver while proximate to the transmitter/receiver, a memory for storing an ID of the cartridge and data relating to the consumable component, and a controller for controlling communication with the transmitter/receiver and for controlling access to the memory, the memory circuit having an anti-collision mode in which the transmitter/receiver checks the ID of the cartridge, and an active mode permitting memory access upon reception of a memory access command from the transmitter/receiver, the memory circuit shifting from a specific state which is not in anti-collision mode to the active mode without passing through the anti-collision mode.

Abstract
The ink unit of a printer has a memory circuit (memory element) for non-contact communication. The memory circuit has a hold mode M2 in which memory access commands from the transmitter/receiver are not received, and an active mode M4 in which memory access is permitted upon receipt of a memory access command. The memory circuit shifts into active mode M4 if the ID contained in the active mode command matches its own ID when an active mode command containing the cartridge ID is received from the transmitter/receiver while in hold mode M2. The reception of an anti-collision start command from the transmitter/receiver while in hold mode M2 results in a shift to anti-collision mode M3 to check the ID.
