    • An image forming apparatus, applicable to copying machines, facsimile apparatuses and printers, controls pixel positions with high precision. An image of color material is formed on the surface of an image holding drum. The surface of the image holding drum divides into a number of pixel areas, and each pixel area has an adhesive-force change portion smaller than the pixel area, where adhesive force to color material changes by a predetermined stimulus. An image-signal input unit forms an image by distribution of adhesive force to the color material on the surface of the image holding drum by inputting a stimulus corresponding to an image signal into the image holding drum. A color material supply unit supplies color material particles to the surface of the image holding drum. A transfer unit transfers an image of the color material particles formed on the surface of the image holding drum, directly or via a predetermined intermediate transfer medium, onto an image print sheet on which the image is finally printed.
    • 适用于复印机,传真机和打印机的图像形成装置以高精度控制像素位置。 在图像保持鼓的表面上形成彩色材料的图像。 图像保持鼓的表面划分为多个像素区域,并且每个像素区域具有小于像素区域的粘附力变化部分,其中着色材料的粘合力改变预定的刺激。 图像信号输入单元通过将与图像信号相对应的刺激输入到图像保持鼓中,通过向图像保持滚筒的表面上的着色材料分配粘合力来形成图像。 彩色材料供应单元将彩色材料颗粒提供到图像保持鼓的表面。 转印单元将形成在图像保持鼓表面上的着色材料颗粒的图像直接或经由预定的中间转印介质转印到最终印刷图像的图像打印纸上。

    • A communication apparatus, such as a facsimile machine, for transmitting and receiving data to and from a device, includes a transmitter for receiving a first signal from the device and transmitting, in response to the first signal, a second signal for a predetermined time period. The transmitter receives a third signal from the device in response to the second signal, and transmits a fourth signal when the third signal is not received within the predetermined time period and transmits a fifth signal when the third signal is received within the predetermined time period. The transmitter receives a sixth signal from the device in response to the fourth signal. A detector, connected to the transmitter, detects which of the third signal and the sixth signal is received from the device. A controller, connected to the transmitter and the detector, controls a protocol of transmission and receipt of the data.

    • A facsimile machine which is provided with functions for executing communication of image data according to ITU-T V.34 mode comprises a communication section, a sequence timer and a control section. The communication section executes a communication sequence for transmitting the image data or receiving the image data. The sequence timer counts a time concerning suspension of the communication sequence according the V.34 mode. The control section changes the communication section into a state for executing communication of image data according to ITU-T V.17 mode, V.29 mode or V.27ter mode, in the case where the sequence timer counted to a predetermined period. Therefore, when the communication sequence according to the V.34 mode stopped for some reasons, the facsimile machine does not wait for recovery of the communication sequence keeping its status until a timeout-period elapses, but monitors the communication sequence until the sequence timer counts to the predetermined period and thereafter changes into the communication sequence according to the V.17 mode, the V.29 mode or the V.27ter mode, thereby communication of fax data can be completed normally even when the sequence according to the V.34 mode stopped, and the sender does not have to be charged with connection charge twice.
    • 具有执行根据ITU-T V.34模式的图像数据通信功能的传真机包括通信部分,序列定时器和控制部分。 通信部分执行用于发送图像数据或接收图像数据的通信序列。 顺序定时器根据V.34模式计算关于通信序列暂停的时间。 在顺序定时器计数到预定时间段的情况下,控制部分将通信部分改变为根据ITU-T V.17模式,V.29模式或V.27ter模式执行图像数据通信的状态。 因此,当根据V.34模式的通信顺序由于某些原因而停止时,传真机不等待保持其状态的通信序列的恢复,直到超时时间过去,而是监视通信序列,直到序列定时器计数 到预定时间段,然后根据V.17模式,V.29模式或V.27ter模式改变为通信序列,从而可以正常地完成传真数据的通信,即使当根据V.34 模式停止,发送方不必对连接费用收取两次费用。
