Patent ID: 7804311

Claim:
An electronic machine connectable to at least one different apparatus, the machine comprising: a first resistor having a first resistance value; a connector configured to be connected to the at least one different apparatus; and a detecting section configured to detect a desired state of the electronic machine from multiple states based on a potential value of a division ratio of the first resistance value of the first resistor and a second resistance value of a second resistor, included in the at least one different apparatus, by identifying the at least one different apparatus when the at least one different apparatus is connected to the connector, and to control at least one pattern of multiple parameters in the detected desired state based on an association of the at least one pattern of multiple parameters with the multiple states of the electronic machine, wherein the association of the at least one pattern with the multiple states is based on the potential values, and the multiple parameters include an input DC current value, the DC current flowing between the electronic machine and the at least one different apparatus, and the DC current value being controllably different depending on the at least one different apparatus.
