Device including replaceable component

A device including a replaceable component, wherein

• the component is:
• a component not electrically connected to the device;
• and
• includes:
• a component-side storage which stores specific identification information of the component and a consumption degree of the component;
• a component-side transmitter/receiver which conducts transmission and reception of electromagnetic waves with the device;
• a component-side hardware processor which controls rewriting of the information in the component-side storage;
• and
• a component-side power generator which generates power for driving the component-side hardware processor, the component-side transmitter/receiver and the component-side storage on the basis of energy generated when the component is attached to/detached from a joint of the device;
• the device includes:
• a main-body side storage which stores specific identification information of the component and the consumption degree of the component;
• a counter which counts up the consumption degree of the component stored in the main-body storage in accordance with use of the component;
• a main-body side transmitter/receiver which conducts transmission and reception of the electromagnetic waves with the component;
• a main-body side hardware processor which controls the transmission/reception of the information with the component;
• a main-body side power generator which generates power for driving the main-body side hardware processor, the main-body side transmitter/receiver, and the main-body side storage on the basis of energy generated when the component is attached to/detached from the joint;
• and
• a detector which detects attachment and detachment of the component to/from the joint;
• and
• the main-body side hardware processor causes the main-body side transmitter/receiver to transmit the specific identification information of the component and the consumption degree of the component stored in the main-body side storage when detachment of the component from the joint is detected;
• and
• the component-side hardware processor rewrites the information in the component-side storage on the basis of the specific identification information of the component and the information of the consumption degree of the component transmitted by the main-body side transmitter/receiver received by the component-side transmitter/receiver.
