    • The subject invention provides an image forming device including a main control section and a signal detection circuit for detecting presence or absence of an external signal supplied to the main control section, and further provided with an interface section for controlling external communication; a main power supply circuit; a power supply control circuit. The signal detection circuit includes a low power mode prohibition circuit for outputting a low power mode prohibition signal for voiding the request for low power consumption with respect to the power supply control circuit or the main power supply circuit while the external signal is supplied to the signal detection circuit. With this arrangement, the present invention provides an image forming device capable of appropriate transition into the low power consumption operation by hardware without use of software.
    • 本发明提供了一种图像形成装置,包括主控部分和信号检测电路,用于检测提供给主控部分的外部信号的存在或不存在,并且还设置有用于控制外部通信的接口部分; 主电源电路; 电源控制电路。 信号检测电路包括低功率模式禁止电路,用于在将外部信号提供给信号的同时,输出低功率模式禁止信号,以排除与电源控制电路或主电源电路相关的低功耗请求 检测电路。 利用这种布置,本发明提供了一种能够在不使用软件的情况下通过硬件适当地转换到低功耗操作的图像形成装置。
