Description

  The present invention relates to an improvement of a document reading apparatus including an automatic document feeder and a flat bed.

Recently, document readers as shown in Patent Document 1 below are widely used in offices and the like. This is equipped with both an automatic document feeder and a flat bed, and when a copy is instructed and the document is placed on both the flat bed and the automatic document feeder, the original on the flat bed is Only the reading by the automatic document feeder is executed assuming that it has been left behind.
JP-A-10-65842

  By the way, in such an apparatus, when an operation for performing reading on the flat bed is performed following the automatic document feeder by a predetermined operation before copying, following the reading of the automatic document feeder. Although the flatbed is read, such an instruction cannot be given during reading by the automatic document feeder because the reading speed of the automatic document feeder is high. For this reason, if no instruction is given in advance before copying, even if the user notices that there is a flatbed document during reading by the automatic document feeder, the flatbed document cannot be read. After reading, the only way to start reading a flatbed document is inconvenient.

  In any case, since the automatic document feeder is preferentially scanned, the user will always notice that the document is placed on the flat bed unless the setting to continue scanning on the flat bed is made. There was also a problem that it was left as it was.

  The present invention has been proposed in view of the above circumstances, and when a document is placed on both the flatbed and the automatic document feeder, a copy is to be made from which the user desires. It is an object of the present invention to provide a document reading device that can set the priority of the document and accurately copy both of the documents placed on both sides to prevent the document from being left on the flat bed. Yes.

  In order to achieve the above object, according to a first aspect of the present invention, there is provided a sensor for detecting document placement on an automatic document feeder, a sensor for detecting document placement on a flood bed, an automatic document reading mode, and a flood. A selection means for selecting which of the bed reading modes is to be prioritized, and when both of these sensors detect document placement, the mode selected by this selection means is prioritized, and then the other Control means for performing the mode.

  According to a second aspect of the present invention, there is further provided display means for displaying whether the automatic document reading mode or the flood bed reading mode is being performed.

  According to a third aspect of the present invention, the selection means includes display means for displaying a mode to be preferentially performed.

According to the first aspect of the present invention, when the sensors of both the automatic document feeder and the flat bed detect document placement, one of the modes selected by the selection unit is preferentially performed, and then the other mode is performed. Therefore, the user can preferentially copy from the necessary side, and the other side also starts when the preferential mode ends, and can copy any original, such as forgetting to place one of the originals or forgetting to copy Can be prevented.

  According to the second aspect of the present invention, display means for displaying either the automatic document reading mode or the flood bed reading mode is further provided, so that it is possible to easily confirm which mode the apparatus is performing.

  According to the third aspect of the present invention, since the selection unit includes a display unit that displays a mode to be preferentially performed, the mode selected to be preferentially performed can be easily confirmed.

  Embodiments of the present invention will be described below. FIG. 1 is a diagram illustrating an example of a configuration of a main part of a document reading apparatus according to the present invention. Here, the configuration of the facsimile apparatus F is shown as an example of the document reading apparatus, but any apparatus having a copying mechanism including an automatic document reading apparatus and a flat bed may be used.

The facsimile apparatus F constitutes control means, and includes a CPU 1 that controls the facsimile apparatus F, an NCU 2 that controls connection to the telephone line L, a modem 3 that modulates and demodulates various signals necessary for facsimile communication, The facsimile apparatus F includes a RAM 4 for registering speed dials and the like, a ROM 5 for storing programs necessary for operation, and a scanner 6 having an FBS sensor S1 and an ADF sensor S2. The scanner 6 includes an automatic document reader and a flat bed. The FBS sensor S1 detects document placement on the flat bed, and the ADF sensor S2 detects document placement on the automatic document feeder.
The facsimile apparatus F includes a display unit 7 that constitutes a display unit, an operation unit 8 that constitutes a selection unit, and a printer 9.

  The scanner 6 will be further described. FIG. 2 is a diagram illustrating an example of a schematic configuration of the scanner 6. As described above, the scanner 6 includes the automatic document feeder 6A and the flat bed 6B. The scanner 6 has an FBS sensor S1 directly below the flat bed 6B, and an ADF sensor S2 at an appropriate position of the automatic document feeder 6A. .

  The document placed on the automatic document feeder 6A passes through the flat bed 6B and the document image is read. The document placed on the automatic document feeder 6A is detected by the ADF sensor S2, and a detection signal is output to the CPU 1.

  On the other hand, the original image placed on the flat bed 6B is read by a reading mechanism located immediately below the original. The document placed on the flat bed 6B is detected by the FBS sensor S1, and a detection signal is output to the CPU 1.

  A copy process when a document is placed on both the automatic document feeder 6A and the flat bed 6B in such a configuration will be described. This will be described with reference to FIG.

  That is, when a document is placed on both sides, both the FBS sensor S1 and the ADF sensor S2 detect the placement of the document, and upon receiving this, the CPU 1 displays a confirmation message (100, 101).

  As an example of such a confirmation message, there is a message as shown in FIG. 4A, which sets whether to give priority to the automatic document feeder (automatic document reading mode) or to give priority to the flatbed (flatbed reading mode). A screen for performing the operation is displayed. The user refers to this screen to set the priority. If the automatic document feeder 6A is prioritized (102), the automatic document feeder 6A starts copying by reading the document (103). Note that if the priority is set, the screen of the display unit 7 may be switched to display the selected priority mode.

  After the start, an indication that reading is being performed by the automatic document feeder 6A is displayed (104). When copying by the automatic document feeder 6A is completed, the document is read by the flat bed 6B. (105). At this time, an indication that the original is being read by the flat bed 6B is displayed (106).

  On the other hand, if the priority is given to the flat bed 6B in the confirmation message (101), reading in the flood bed 6B is started (107) and a message to that effect is displayed (108). When all the originals have been read on the flat bed 6B (a predetermined end operation is performed), reading by the automatic document feeder 6A is started and a message to that effect is displayed (110, 111). Note that a message as shown in FIG. 4B is displayed every time one document reading on the flat bed 6B is completed, and “read” is selected when reading continuously, and “end” when finished. Select.
