    • A coordinate input apparatus of the present invention in which operation is switchable from an image pickup mode for displaying on a display apparatus an image of an object for image-taking to a coordinate input mode for inputting coordinates at a location indicated by a point indicator and vice versa, so that when the coordinate input mode is set, the duration of scanning by an image pickup element is controlled shorter than that in the case of the image pickup mode being set, whereby the duration required for image pickup during coordinate input mode operation can be reduced and speedy processing can be achieved for coordinate inputting, and which is provided with an image processing circuit for optimum image processing with respect to image signals for images taken, so that images taken in short image pickup duration during coordinate input mode can be prevented from deterioration.
    • 本发明的坐标输入装置,其特征在于,从图像拾取模式切换操作,在显示装置上显示用于拍摄对象的图像到用于在由点指示器指示的位置处输入坐标的坐标输入模式, 反之亦然,使得当设置坐标输入模式时,由图像拾取元件进行的扫描的持续时间被控制得比设置图像拾取模式的情况更短,从而在坐标输入模式操作期间所需的图像拾取所需的持续时间 可以减少并且可以快速地进行坐标输入处理,并且其具有用于对于所拍摄的图像的图像信号进行最佳图像处理的图像处理电路,使得在坐标输入模式期间以短图像拾取持续时间拍摄的图像可以是 防止恶化。

    • In an image pickup apparatus according to the present invention, a rotary scanning mirror (2) is rotated to sense the image of an original (10) by a linear image sensor (4), which in turn outputs picture signals to be stored in a frame memory (5), so that the image of the original (10) is displayed on a display unit (6) on the basis of the stored picture signals. A light pen (9) specifies a scanned range of the image displayed on the display unit (6) and a controller (8) indicates rotation angles of the rotary scanning mirror (2) on the basis of position signals from the light pen (9) to specify the scanned range while varying the step size of the rotary scanning mirror (2) thereby to vary resolution. Thus, a noted region in the original (10) can be easily image-sensed in high resolution.
    • 在根据本发明的图像拾取装置中,旋转扫描镜(2)被旋转以通过线性图像传感器(4)感测原稿(10)的图像,该线性图像传感器又输出要存储在其中的图像信号 帧存储器(5),使得原始(10)的图像基于存储的图像信号显示在显示单元(6)上。 光笔(9)指定在显示单元(6)上显示的图像的扫描范围,并且控制器(8)基于来自光笔(9)的位置信号来指示旋转扫描镜(2)的旋转角度 )来指定扫描范围,同时改变旋转扫描镜(2)的步长,从而改变分辨率。 因此,原始(10)中的注意区域可以以高分辨率容易地图像感测。

    • An image-transfer-type electrostatic recording apparatus in which an endless-belt-shaped latent-electrostatic-image-bearing recording medium is trained over a drive roller and a driven roller so as to be rotatable therearound. The rollers are supported by a frame member. The latent electrostatic images are developed to visible images during the rotation of the latent-electrostatic-image-bearing recording medium, and the developed visible images are then transferred to a recording sheet. A device corrects the skewing of the endless-belt-shaped recording medium by moving upwards or downwards one end portion of the driven roller. A recording sheet guide member guides the recording sheet to a predetermined image transfer section on the surface of the developed visible image bearing recording medium. The recording sheet guide member is substantially integral with the frame member and/or the driven roller, thereby guaranteeing appropriate contact of the recording sheet with the recording medium regardless of the movement of the driven roller for correcting the skewing of the endless-belt-shaped recording medium.
    • 一种图像转印型静电记录装置,其中环形带状潜影静电图像承载记录介质被训练在驱动辊和从动辊上,以便可绕其旋转。 辊由框架构件支撑。 在静电潜像记录介质旋转期间,将静电潜像显影成可视图像,然后将显影的可见图像转印到记录纸上。 装置通过向上或向下移动从动辊的一个端部来校正环形带状记录介质的倾斜。 记录纸引导构件将记录纸引导到显影的可见图像承载记录介质的表面上的预定图像转印部。 记录纸引导构件与框架构件和/或从动辊基本上是一体的,由此保证记录纸与记录介质的适当接触,而不管用于校正无级带状的歪斜的从动辊的移动 记录介质。
