    • An image input output apparatus includes an image reading portion arranged to be freely opened and closed for reading an image and an image forming portion for forming a print image, so that the image input output apparatus capable of reading and printing the image. The image input output apparatus further includes a power supply portion for supplying power to each of the image reading portion and the image forming portion independently, and a detection portion for detecting whether the image reading portion is opened or closed. The power supply portion is arranged to become a first power save mode, in which the power supply portion reduces power supplied to the image reading portion when the detection portion detects that the image reading portion is opened.
    • 图像输入输出装置包括被布置为自由地打开和关闭以读取图像的图像读取部分和用于形成打印图像的图像形成部分,使得能够读取和打印图像的图像输入输出装置。 图像输入输出装置还包括用于独立地向每个图像读取部分和图像形成部分供电的电源部分和用于检测图像读取部分是打开还是关闭的检测部分。 供电部被配置为成为第一省电模式,其中当检测部分检测到图像读取部分被打开时,电源部分减小供应给图像读取部分的电力。

    • An image forming apparatus comprising: a sound-level meter that measures operating noise of a rotating portion; a sound data generator that generates a noise control sound data object with the same amplitude but with the inverted phase to the operating noise; a speaker that emits sound based on the noise control sound data object; a memory that stores in advance a noise control sound data object generated to cancel out operating noise measured while the rotation frequency of the rotating portion is changed from a first rate to a second rate; and a controller that measures operating noise of the rotating portion and generates a noise control sound data object to cancel out the operating noise, then emits sound based on the noise control sound data object, while the rotating portion runs in steady state, meanwhile reads out from the memory, a suitable noise control sound data object from the memory and emit sound based on the noise control sound data object, during the transition of the rotation frequency of the rotating portion.
    • 一种图像形成装置,包括:声级计,其测量旋转部分的操作噪声; 声音数据发生器,产生具有相同振幅但具有反相的噪声控制声音数据对象与操作噪声; 基于噪声控制声音数据对象发出声音的扬声器; 存储器,其预先存储产生的噪声控制声音数据对象,以消除在旋转部分的旋转频率从第一速率变为第二速率时测量的操作噪声; 以及控制器,其测量旋转部分的操作噪声并产生噪声控制声音数据对象以抵消操作噪声,然后在旋转部分稳定运行的同时基于噪声控制声音数据对象发出声音,同时读出 从存储器中,在旋转部分的旋转频率的转变期间,来自存储器的合适的噪声控制声音数据对象基于噪声控制声音数据对象发出声音。
