Abstract

One of two replaceable components is selectively detachably attached to an apparatus. A first component includes first information that includes first lifetime indicative of a lifetime of the first component and is used for managing usage of the first component. A second component includes second information for managing usage of the second component. A controller determines, based on one of the first and second lifetimes, whether the apparatus should operate. The controller drives the apparatus to operate based on the first lifetime if a read/write section successfully reads the first lifetime from one of the first and second components that has been attached to the apparatus. The controller drives the apparatus to operate based on the second lifetime if the read/write section fails to read the first lifetime from one of the first and second components that has been attached to the apparatus.

First claim

What is claimed is:

1. An electronic apparatus comprising:
a body;
a replaceable component detachably attached to the body, and including a first memory that stores information about the replaceable component;
a second memory that is disposed within the body and stores first lifetime information therein;
a reading section configured to read the information about the replaceable component from the first memory; and
a controller configured to manage a lifetime of the replace…
