Abstract

Provided is an electric apparatus including a reception unit (for example, hardware key) for receiving an instruction relating to functions of the electric apparatus and having operation states of a power conserving state in which power required for performing the functions thereof is limited and a normal state in which the power is not limited, wherein the reception unit may receive an instruction indicating a return to the normal state in the power conserving state and receive an instruction which is to be originally received in the normal state. When the reception unit receives the instruction, signals at different levels are output depending on the operation state and based on the signal to be output, a return signal relating to the return to the normal state or an execution signal relating to the execution of a function corresponding to the instruction received by the receiving signal is output.

Claims

1. An electric equipment including a reception unit configured to receive an instruction relating to functions of the electric equipment by an operation of a user and having operation states of a power conserving state in which power required for performing the functions thereof is limited and a normal state in which the power is not limited, the electric equipment comprising:

a signal output unit configured to output signals of different levels depending on the operation state when the reception unit receives the instruction from the user; and

a control signal unit configured to selectively output a return signal relating to a return to the normal state or an execution signal relating to an execution of a function corresponding to the instruction received by the reception unit, based on the signal output from the signal output unit.

2. The electric equipment according to claim 1, wherein the signal output unit has two terminals configured to output signals to the control signal unit, and

the control signal unit outputs the return signal or the execution signal, based on a signal level relating to any one of the two terminals which are defined by the operation state.

3. The electric equipment according to claim 1, wherein the control signal unit includes:

a return signal unit which has two input terminals corresponding to the terminals of the signal output unit, and is configured to output the return signal; and

an execution signal unit configured to output the execution signal,

wherein the return signal unit outputs the return signal based on the signal level of one input terminal of the two input terminals, and the execution signal unit outputs the execution signal based on the signal level of the other input terminal.
