Electronic apparatus that conserves energy

摘要

An electronic apparatus (1) suppresses consumption of power by saving power for the electronic apparatus main body (50) and a communicating module (20). In a printing apparatus, power saving mode setting processing is carried out if the printing apparatus is not used in a specified time interval. More specifically, a printing portion (41) is changed into a sleep mode and the communicating module (20) is changed to power saving mode depending on an amount of power remaining in a battery (30) and power ON passage time. Further, auto power OFF setting time is changed depending on the amount of power remaining in the battery. For example, the mode of the communicating module is changed among a plural modes classified depending on consumption of power supplied from the battery and used by the communicating module.
