    • PROBLEM TO BE SOLVED: To provide a technique for speedily switching a display screen from a standby screen to a function selection screen, in an information processor which displays a screen on a display unit on the basis of screen data obtained from a server device.SOLUTION: While displaying on a display unit a standby screen based on screen data obtained from a server device (web server) (S404) in a standby state, an information processor (MFP) obtains, from the web server, screen data on a function selection screen (initial screen) (S406). Thereafter, during displaying the standby screen, when instructed to close the standby screen (S408), the MFP switches the display on the display unit from the standby screen to the function selection screen based on the obtained screen data (S409).

    • PROBLEM TO BE SOLVED: To provide control technique for effectively reducing power consumption in an image formation device.SOLUTION: A first sub-CPU 107 performs an automatic response in a network when a power supply to a main CPU 103 is interrupted and also an image formation device 100 is connected to a network. A second sub-CPU 110 is configured to determine whether or not an operation mode is changed from a standby mode into a power saving mode, to control the interruption of power supply to a main CPU circuit 104 in accordance with the determination result, to determine via the first sub CPU 107, a state concerning the connection of the image formation device 100 to the network when changing the operation mode from the standby mode into the power saving mode, to monitor a recovery factor when changing the operation mode from the standby mode into the power saving mode, and to change the operation mode from the power saving mode into another operation mode in accordance with the detected recovery factor when the recovery factor is detected.
    • 要解决的问题:提供用于有效降低图像形成装置中的功率消耗的控制技术。 解决方案:当对主CPU 103的电源被中断并且图像形成装置100连接到网络时,第一子CPU 107执行网络中的自动响应。 第二子CPU 110被配置为确定操作模式是否从待机模式改变为省电模式,以根据确定结果控制对主CPU电路104的电力供应中断,以确定 通过第一副CPU 107,将从待机模式变更为省电模式时的图像形成装置100与网络的连接状态,监视从待机模式变更操作模式时的恢复率 进入省电模式,并且当检测到恢复因子时,根据检测到的恢复因子将操作模式从省电模式改变为另一操作模式。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To prevent overvoltage applied to a signal buffer circuit due to excessively large or small output and a disturbed signal from load of CCD and the like.SOLUTION: A signal buffer circuit comprises a resistor (R) 12 connected between an input part and an output part of a buffer 11 which is resistance means of high resistance and an impedance variable element (VZ) 13 connected to the output part in series which is impedance variable means with impedance being varied. The impedance variable element 13 is in a low impedance state when the buffer 11 is turned on (the buffer operates), and in a high impedance state when the buffer 11 is turned off (the buffer does not operate: reverse bias is applied between the input and output parts).
