Abstract
Disclosed is an image recording apparatus capable of preventing maloperations when entering into sleep mode. The image recording apparatus comprises a display module, a detecting unit, a power supply unit, a first switch, a second switch and a control unit having an interrupt unit. The control unit controls the first switch in an on-state to supply power to the display module and the detecting unit and executes a corresponding operation. After an idle status of the image recording apparatus exceeds a predetermined time, the control unit disables the interrupt unit and controls the second switch in an on-state and the first switch in an off-state to supply power to the detecting unit via the second switch. After a default time, the control unit enables the interrupt unit, therefore, maloperations when entering into the sleep mode can be prevented.
