ABSTRACT:
A reading apparatus serving as an input means for simultaneously reading printed image information from both the front and back of a document, converting the read information into digital data, and storing the digital data on a data recording medium, such as an optical disk, comprises document carrier mechanisms, a front reading sensor, a back reading sensor, a front size determining sensor, a back size determining sensor, a document size comparator, and a reading control circuit. These components are incorporated in the reading apparatus. The document carrier mechanisms carry documents inserted through a slot through the apparatus and eject them through an outlet. The front data reading sensor and back data reading sensor read printed images from the front and back of a document. The front size determining sensor and back size determining sensor are located upstream of the front data reader in the document carrier path, and detect the sizes of the front and back of a document. The document size comparator compares between the sizes determined by the front size determining sensor and back size determining sensor, and outputs a larger one of determined sizes as the document size. The reading control circuit controls reading of image data from the front and back of a document according to the document size provided by the document size comparator.
