Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reads an area designation sheet before starting reading of an original sheet, stores the content in a memory, and stores the original sheet based on the area stored in the memory. The present invention relates to a document reading device in a copying machine that performs image processing.

2. Description of the Related Art Conventionally, in the copying machine as described above, when the area designation sheet is read, the area designation sheet is read after the switch for putting the memory into the storage state is turned on, and then the original sheet is read. Is designed to feed the original sheet by turning on the switch that puts the memory in the original reading state. The different switches are turned on and off twice to read the area designation sheet and the original sheet. Was there.

Problems to be Solved by the Invention As described above, in the conventional copying machine, the operator has to turn on and off different switches for reading the area designation sheet and the document sheet. There was a problem that it was miscellaneous.

Therefore, an object of the present invention is to provide a document reading apparatus which solves the problems of the document reading apparatus in the conventional copying machine as described above and can read the area designation sheet and the document sheet with one operation. There is.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention designates an odd-numbered sheet area designation in which a predetermined area is designated before starting the reading of a document in a conventional copying machine. In a copying machine that scans a document sheet and stores the area designation data in the memory, and the original data read from the even-numbered original sheet is processed separately for each area based on the area stored in the memory. A sending means and a system control section are provided, and the sheet automatic sending means is provided with a sheet pedestal. The area specifying sheet and the original sheet are set in this sheet pedestal in this order, and the sheet automatic sending is performed. By the operation of the means, an odd numbered area designation sheet is sent from the sheet receiving table, and the area designation data of this area designation sheet is transferred to the system control unit. The original data stored in the memory is then sent out from the sheet pedestal, and the even-numbered original sheet is sent out, and the original data read from this original sheet is processed separately for each area of the area designation data stored in the memory. It is characterized by being performed.

Embodiment An embodiment of the present invention shown in the drawings will be described.

In the copying machine shown in FIG. 1, as shown in the flow chart of FIG. 3, a plurality of sheets A are fed by the feed roller 1 rotating in the arrow direction. With the exception of the one abutting on 1, its advance is blocked. The sheet A thus fed onto the sheet pedestal 4 is fed by the two pairs of feeding rollers 3 arranged on both sides of the sheet pedestal 4, and these rollers 1 and 3 are used by the system. It is driven by a drive source (not shown) according to a command from the control unit 13.

In this case, when using the area designation sheet a as shown in FIG. 2, the operator superimposes the sheet a on the original sheet b, and the boundary line c for discriminating the area is set by using an arbitrary writing instrument. Fill out. Next, the sheets a and b thus superposed are inverted and placed on the sheet receiving table 4 so that the writing surface faces down, the sheet a faces down, and the sheet b faces up.

When the operator presses the start button of the operation unit (not shown), the area designation sheet a is first sent out, and the light from the light source 5 is applied to the sheet a on the sheet pedestal 4.
The reflected light is input to the image sensor 8 through the mirror 6 and the lens 7. The image sensor 8 is a line sensor composed of a solid-state image sensor such as a CCD type, which photoelectrically converts an input optical signal and outputs an electric signal corresponding to the optical signal.

The output of the image sensor 8 is input to the A / D converter 9, where the analog signal is converted into a digital signal and stored in the area storage memory 10. The storage memory 10 has a capacity capable of storing image data corresponding to one page of the area designation sheet a, and is a system so that it can be stored only when the first sheet, that is, the area designation sheet a is sent. It is controlled by the control unit 13.

When the area designation sheet a is thus fed and the designated area is stored in the memory 10, the original sheet b is then fed. When the reading of the image on the original sheet b starts, the area data stored in the area storage memory 10 is read synchronously and input to the image signal processing unit 11.

In the image signal processing unit 11, based on the area storage data,
The inside / outside of the area is determined and the image signal is output to the recording device 12. The recording device 12 has a recording member such as a thermal head, and forms an image on a recording sheet (not shown) according to an input image signal.

In this embodiment, the description has been made on the assumption that only one set in which the area designation sheet a and the original sheet b are combined one by one is sent, but even if such a combination is placed on the several set sheet pedestal 4. Alternatively, unlike this, they may be sequentially placed one by one, and in any case, the odd numbered feed sheets are handled as the area designation sheets and stored in the area storage memory 10.

The present invention is as described above, and in the conventional copying machine, a sheet automatic feeding means and a system control section are provided, and the sheet automatic feeding means is provided with a sheet receiving table. The area specifying sheet and the original sheet are set together in this order, and an odd numbered area specifying sheet is sent from the sheet receiving table by the operation of the sheet automatic sending means, and the area specifying sheet area is set. The system controller causes the system control unit to store the designated data in the memory, then sends out an even-numbered original sheet from the sheet tray, and the original data read from the original sheet is used as the area designation data stored in the memory. Since different processing is performed for each area, the sheet automatic feeding means is activated by operating the document reading device, and first, for area designation. Storage of area designation data in the memory by the system control unit after the sheet is sent out, and area-specific processing of original data in the area designation data stored in the memory is automatically performed successively in succession, The entire work time is short, the work can be performed with high efficiency, and the area designation sheet and the original sheet are set as a set on the sheet pedestal. There is no difference in the orientation between the original sheet and the original sheet, the consistency is maintained well, and the malfunction does not occur.
