The present invention provides a scanner apparatus provided with both a flatbed-type mechanism and an ADF-type mechanism. The ADF mechanism can be set at an arbitrary position with an arbitrary orientation for use, whereby convenience for the user is improved while ensuring freedom with regard to the setting place of the apparatus. Further, the scanner apparatus is made such that reading with the ADF unit and reading with the flatbed unit can be performed simultaneously. A movable coupling mechanism is provided at a joint portion between the ADF mechanism and the flatbed mechanism. The movable coupling mechanism does not fix the position and orientation of the ADF mechanism and enables the ADF mechanism to be freely moved and rotated. With this movable coupling mechanism, the ADF mechanism can be disposed at either of the left and right ends of the paper-pressing board of the flatbed unit or at an arbitrarily position in consideration of convenience for a user and the setting place of the apparatus. Further, the orientation of the shooter of the ADF mechanism can be freely changed.

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.

The platen includes a first, black portion located under the original and a second, white portion located outside the original. The widths of the first and second portions are automatically changed. The platen is formed by an endless belt having a triangular black region and a complementary white region. The endless belt is moved so that the width of the triangular black region at the reading position corresponds to the width of the original. The platen is alternatively formed as a box-shaped member or of liquid crystal panel.

An input receiving apparatus receives an input such as an order slip transmitted from a facsimile apparatus at a user terminal. The user makes a conversation reservation before the user transmits the image data of the order slip. After the input receiving apparatus receives the image data, the input receiving apparatus switches a connection line from a facsimile receiving apparatus to a facsimile transmitting apparatus within the input receiving apparatus within the same call upon receipt of the conversation reservation signal automatically transmits a switching signal to the facsimile apparatus at the user end and performs a character recognition by extracting a character portion from the image data, thereby preparing a return image data based on the character recognition. When the facsimile apparatus at the user end is ready for receiving the return image data, the input receiving apparatus transmits the return image data. The user confirms his order by observing the return image and then issues a PB signal.
