Data processing device and power saving control method
First Claim
1. A data processing device which can communicate with a computer terminal, comprising:
- a reception unit adapted to receive data transmitted from the computer terminal;
a shift unit adapted to shift a state of said data processing device to a power saving state after elapse of a predetermined time under a state that no data is received by said reception unit; and
a release unit adapted to release the power saving state in a case where specific data transmitted from the computer terminal is received by said reception unit,wherein, after the power saving state is released by said release unit,in a case where the specific data received by said reception unit is a first kind of the specific data and the power saving state is released by said release unit, said shift unit shifts the state of said data processing device to the power saving state after elapse of a first predetermined time, andin a case where the specific data received by said reception unit is a second kind of the specific data different from the first kind of the specific data and the power saving state is released by said release unit, said shift unit shifts the state of said data processing device to the power saving state after elapse of a second predetermined time different from the first predetermined time.

Abstract
A data processing device which can communicate with a computer terminal, comprises: a receiver to receive data transmitted from the computer terminal; a shifter to shift a state of the data processing device to a power saving state, after elapse of a predetermined time; and a releaser to release the power saving state according to specific data transmitted from the computer terminal, wherein, after the power saving state was released by the releaser, when the received data is first kind of data, the shifter shifts the data processing device to the power saving state after elapse of a first predetermined time, and, when the data received by the receiver is second kind of data different from the first kind of data, the shifter shifts the data processing device to the power saving state after elapse of a second predetermined time different from the first predetermined time.

7. A power saving control method for a data processing device which can communicate with a computer terminal, said method comprising:
-
a reception step of receiving data transmitted from the computer terminal; a shift step of shifting a state of the data processing device to a power saving state after elapse of a predetermined time under a state that no data is received in said reception step; and a release step of releasing the power saving state in a case where specific data transmitted from the computer terminal is received by said reception unit, wherein, in said shift step, after the power saving state is released in said release step, in a case where the specific data received in said reception step is a first kind of the specific data and the power saving state is released in said release step, the state of the data processing device is shifted to the power saving state after elapse of a first predetermined time in said shift step, and in a case where the specific data received in said reception step is a second kind of the specific data different from the first kind of the specific data and the power saving state is released in said release step, the state of the data processing device is shifted to the power saving state after elapse of a second predetermined time different from the first predetermined time in said shift step. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
