Image forming apparatus and image forming method
First Claim
1. An image forming apparatus comprising:
- a processor configured to;
control the image forming apparatus in any one of a plurality of apparatus states including at least a normal state, which is a printable state, and a power saving state, which is an unprintable state and in which power consumption is lower than power consumption in the normal state;
determine position information of a mobile terminal which is carried by a user, based on a signal strength in wireless communication that is performed between the mobile terminal and at least one radio device which is disposed at a predetermined position; and
determine whether or not to change a control state from the power saving state to the normal state, based on the position information of the mobile terminal that is carried by the user who issues a printing instruction, in the mobile terminal,wherein the processor is configured to change the control state from the power saving state to the normal state, according to a determination result of the processor,wherein the at least one radio device includes a plurality of radio devices, andwherein the predetermined positions of the radio devices include a first position and a second position that is closer to the image forming apparatus than the first position,wherein the processor is configured to acquire position information of the mobile terminal, based on a first signal strength which is a signal strength in wireless communication that is performed between the radio device at the first position and the mobile terminal, and based on a second signal strength which is a signal strength in wireless communication that is performed between the radio device at the second position and the mobile terminal.

Abstract
An image forming apparatus includes a state control unit, a position information acquisition unit, and a power control determination unit. The state control unit controls the image forming apparatus in at least a normal state and a power saving state. The position information acquisition unit determines position information of a mobile terminal, based on a signal strength in wireless communication that is performed between the mobile terminal and a radio device disposed at a predetermined position. The power control determination unit determines whether or not to change a control state from the power saving state to the normal state, based on the position information of the mobile terminal that issues a printing instruction. The state control unit changes the control state from the power saving state to the normal state, according to a determination result of the power control determination unit.

12. An image forming method comprising:
-
acquiring position information of a mobile terminal which is carried by a user, based on a signal strength in wireless communication that is performed between the mobile terminal and at least one radio device which is disposed at a predetermined position; determining whether or not to change a control state from a power saving state to a normal state, among a plurality of apparatus states including at least the normal state which is a printable state and the power saving state, based on position information of the mobile terminal that is carried by a user who issues a printing instruction, in the mobile terminal; changing the control state of an image forming apparatus from the power saving state to the normal state according to a determination result, wherein the predetermined position where the at least one radio device is disposed is a position of the image forming apparatus or a position close to the image forming apparatus, wherein the at least one radio device includes a plurality of radio devices, and wherein the predetermined positions of the radio devices include a first position and a second position that is closer to the image forming apparatus than the first position; and acquiring the position information of the mobile terminal based on a first signal strength which is a signal strength in wireless communication that is performed between the radio device at the first position and the mobile terminal, and based on a second signal strength which is a signal strength in wireless communication that is performed between the radio device at the second position and the mobile terminal. - View Dependent Claims (13, 14, 15)
