摘要： The original documents of A4 or A3 format are selectively read by a scanning apparatus (2) which is integrated into a system for producing and transmitting images. The originals of A4 format are normally positioned on a fixed exposure surface (5) and the originals of A3 format are introduced into a separate device (7) for transporting documents, which is adjacent to the fixed exposure surface (5). A carriage (22) with lamps (36) is slidable below the exposure surface (5) to illuminate the A4 original while to illuminate the A3 original the carriage (22) is moved into a fixed position (23) corresponding to the separate reading device (7) where the original A3 is slid with respect to the carriage past an exposure zone (E). The reflected images of the originals are passed by means of mirrors (40,42,44) mounted on the carriage (22) to a lens (45) which reflects them on to a photodetector device which converts the light rays into digital electrical signals. To adjust the focal lengths of the lens (45) to the various dimensions of the A3 and A4 formats and to compensate for the different distances (difference D) of the two types of originals from the lens, two of the mirrors (42,44) are mounted on an auxiliary frame which is movable on the carriage. The auxiliary frame is displaced by its own motor (76) and a lead-screw (70) to different positions in relation to the type of original which is to be read.

摘要： The device comprises a colour indicator (47) for recording a signal (44) in association with a reading signal for a predetermined colour (G). The colour indicator signal is derived from a table of zones of colours which is recorded in a ROM and can be addressed by the reading signals of the various colours, input from corresponding reading elements via compensation circuits (14G,14R,14B). The colour signal is capable of controlling second selective scanning of document for recording the reading signals for all the primary colours of the image. The ROM is also capable of providing an indication of the mixture of colours of each pixel, which is compared (51) to a predetermined mask (M) for the purposes of suppressing a particular mixture of colours from the recording.

摘要翻译： A4或A3格式的原始文件由集成到用于产生和发送图像的系统的扫描装置（2）选择性地读取。 A4格式的原稿通常位于固定的曝光表面（5）上，A3格式的原稿被引入到与固定曝光表面（5）相邻的用于传送文件的单独的装置（7）中。 具有灯（36）的托架（22）可在曝光表面（5）的下方滑动以照亮A4原稿，同时照亮A3原稿，托架（22）移动到对应于单独读取装置的固定位置（23） （7）其中原始A3相对于滑架经过曝光区（E）滑动。 原稿的反射图像通过安装在滑架（22）上的反射镜（40,42,44）传递到透镜（45），该透镜将它们反射到将光线转换成数字电信号的光电检测器装置。 为了将镜头（45）的焦距调整为A3和A4格式的各种尺寸，并补偿两种类型的原稿与镜头的不同距离（差值D），其中两个镜子（42,44 ）安装在可在托架上移动的辅助框架上。 辅助框架通过其自身的电动机（76）和导螺杆（70）相对于要读取的原稿的类型而移动到不同的位置。
