    • An image reading apparatus has line sensors for optically reading an image carried on an image placed on a subject table and producing an image signal. The line sensors are displaceable by a piezoelectric device which is mounted on a support base by an attachment unit. The attachment unit has an attachment member including a bottom wall having two threaded holes defined therein that are spaced from each other by a given distance Ld. The attachment unit also has an adjustment member which has a screw insertion hole defined therein and extending from rear to front surfaces thereof for insertion therethrough of a screw for horizontally holding the piezoelectric device, and two positioning oblong holes defined vertically therein for passage therein of bolts threaded respectively in the threaded holes in the bottom wall of the attachment member. The attachment unit allows the piezoelectric device to have its projection length adjustable with ease, and also to be replaced independently with a new one, for thereby dispensing with repeated optical positional adjustments, increasing the quality of reproduced images, and reducing the cost of the image reading apparatus.
    • 图像读取装置具有线传感器,用于光学地读取放置在被摄体台上的图像上承载的图像并产生图像信号。 线传感器可由通过附接单元安装在支撑基座上的压电装置移动。 附接单元具有附接构件,该附接构件包括具有限定在其中的两个螺纹孔的底壁,彼此间隔开给定的距离Ld。 安装单元还具有调节构件,该调节构件具有限定在其中的螺钉插入孔并且从后表面延伸到前表面以插入用于水平保持压电装置的螺钉,以及两个垂直定位的定位长孔,用于在其中通过螺栓 螺纹分别在连接构件的底壁中的螺纹孔中。 附接单元允许压电装置的突出长度可以容易地调节,并且还可以独立地用新的替换,从而分配重复的光学位置调整,增加再现图像的质量,并降低图像的成本 阅读设备

    • A discrimination device which is disposed on a conveyance path of conveyed items, such as planographic printing plates, slip sheets and the like. The discrimination device is structured with a first sensor, which detects presence or absence of the conveyed items, and second and third sensors, which identify types of the conveyed items. The first sensor can judge presence or absence of a conveyed item from whether or not irradiated light is reflected by a conveyed item. The second and third sensors discriminate between the types—the planographic printing plates and the slip sheets—by the intensity of reflected light, on the basis of a difference in surface reflectivities of the conveyed items. With these three optical sensors, it is possible to reliably identify four conveyance configurations of the conveyed items.
    • 一种辨别装置,其设置在诸如平版印刷版,滑片等的输送物品的输送路径上。 识别装置由检测输送物品的存在或不存在的第一传感器以及识别被传送物品的类型的第二和第三传感器构成。 第一传感器可以判断被传送物品的存在与否是否被照射的光是否被被传送物体反射。 第二和第三传感器基于所输送物品的表面反射率的差异,区分平版印刷版和滑动片的类型 - 反射光的强度。 利用这三个光学传感器,可以可靠地识别输送物品的四个输送构造。
