Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a facsimile machine capable of sheet reading and book reading.

[0002]

2. Description of the Related Art In recent years, with the combination of image copying means and image transmitting means, a combined image communication apparatus such as a copying machine or a facsimile has been developed.

However, since the book reading mechanism of the copying machine and the sheet reading mechanism of the facsimile using the ADF are largely different, the reading mechanism of the combined product is larger and more expensive than the uncombined product. Many reading mechanisms use CCD elements, but the use of CCD elements requires a large optical path length, resulting in a large device. Therefore, a compact composite type image communication device using a contact image sensor (CS) has been recently developed.

[0004]

However, in a conventional facsimile apparatus having a copying function, when transmitting a book original, the original is first read and stored in a memory and then transmitted. Therefore, one of the book manuscripts
The memory for pages was required, and the manufacturing cost of the device was high. In addition, even in a facsimile apparatus having a broadcast transmission function, since all originals are read and stored in a memory before transmission, a memory for storing the originals is required, which increases the manufacturing cost of the apparatus. Was there.

[0005]

In order to solve such a problem, the invention according to claim 1 proposes a document table on which a book document is placed, a sheet document holding means for placing a sheet document, and the sheet document holding. ADF means for continuously supplying the sheet original placed on the means, a photoelectric conversion element for converting input light into an electric signal, and the book placed on the original table by moving the photoelectric conversion element. A book document reading means for reading a document and the photoelectric conversion element are fixed,
A sheet document reading unit that reads the sheet document while moving the sheet document supplied by the ADF unit, a transmission unit that transmits the read image, and a sheet document holding unit when the transmission of the book document is completed. And a communication completion means for transmitting a communication completion signal notifying that the communication is completed, regardless of whether or not the original is held.

According to a second aspect of the invention, there is provided the facsimile apparatus according to the first aspect, further comprising broadcast transmitting means for transmitting to a plurality of destinations, and transmitting to each of the plurality of destinations. The book document is read by the book document reading unit every time.

The invention according to claim 3 is the facsimile apparatus according to claim 2, wherein the broadcast transmitting means is effective when transmitting a book original, and when transmitting a sheet original. It is not effective.

[0008]

According to the present invention, when the transmission of the book document is completed, the communication is completed regardless of whether the document is held in the sheet document holding means. In particular, in the case of broadcast transmission, the book original is read by the book original reading means each time it is sent to each of a plurality of destinations. Since the broadcast transmission means is effective only when transmitting a book document and not effective when transmitting a sheet document, a page memory is not required.
