Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile broadcasting apparatus capable of transmitting even when transmission information increases due to an increase in the number of originals or an increase in the content of originals.

As a conventional facsimile broadcasting apparatus, for example, a plurality of lines are collectively read by a reading element such as a CCD, the read signal is stored in a line memory, and then read to be MH (Modified Huffman, one-dimensional band compression). ) Method or MR (Modified Read, two-dimensional band compression) method, and encode the encoded signal by 2 to 4
There is an M-bit storage unit that stores the data in an M-bit storage unit and sequentially transmits it to a plurality of receiving stations based on the stored contents of the storage unit.

However, in the conventional facsimile broadcasting apparatus, if the transmission information increases due to an increase in the number of originals or the density of originals exceeds the storage capacity of the storage unit, a fault (FAULT) state is set and then The operation of the entire system is stopped, or only the stored contents are transmitted and the operation thereafter is stopped, so there is a limit to improvement in operability.

The present invention has been made in view of the above, and the stored original information is stored in order to improve the operability by enabling transmission even when the transmission information increases due to an increase in the number of originals or a high density of original contents. When a predetermined storage capacity level is reached, the reading of the original is interrupted, the original information is transmitted to the designated receiving station, and then the reading of the original is resumed. .

The facsimile broadcasting apparatus of the present invention will be described in detail below.

The attached drawings show an embodiment of the present invention, in which a main body 1 is provided with a document supply tray 2, a platen 3 and a discharge tray 4. The document supply tray 2 is provided with a document supply pulley 6 for sequentially supplying the stacked documents 5 from the lower layer, and the platen 3 is provided with a document transfer roll 7 and a document discharge roll 8. Below the platen 3 are original scanning lamps 9a and 9b.
And a reading unit 11 such as a CCD that receives scanning light via the condenser lens 10. A line memory 13 is provided downstream of the reading unit 11, and a data compression unit 1 for compression-encoding the stored contents of the line memory 13 based on the MH system, MR system, or the like.
4, a storage unit 15 of 2M to 4M bits for storing compression-encoded data, and a storage content of the storage unit 15 is modulated.
MODEM16 and NCU that controls the connection to the system line
(Network Control Unit) 17 is connected. The above circuits are input / output interface, ROM, RAM and CP
It is controlled by the system control unit 18 having U, and the system control unit 18 checks the memory use state of the storage unit 15 and controls the drive unit 20 of the motor 19 which drives the document supply pulley 6 based on the result. .

In the above configuration, to explain the operation, after placing the document 5 on the document supply tray 2, a plurality of receiving stations are designated (input by key operation of a console not shown),
When the start key (provided on the console) is turned on, operation signals based on these operations are sent to the control unit 18.
The control unit 18 outputs a control signal for controlling each unit. When the drive section 20 is actuated by the control signal to drive the motor 20 and the document supply pulley 6 supplies the document 5, the document transfer roll 7 (also similarly controlled by the control section 18) is moved onto the platen 3. 5 is transferred. The document 5 is illuminated by the lamps 9a and 9b while being read by the reading unit 1.
1, the document is scanned, and the contents are scanned by the line memory 13
After being stored in the MH
The data is compressed into compression encoded data based on the method or the MR method and stored in the storage unit 15. The plurality of originals 5 on the original supply tray 2 are sequentially guided to the platen 3 and the contents of the originals are stored in the storage unit 15 by repeating the above-described operation. When this operation is completed for all the originals 5, the contents stored in the storage unit 15 are modulated by the MODEM 16 and transmitted to one of the receiving stations designated by the control of the NCU 17. When a plurality of receiving stations to be transmitted are designated, this operation is repeated to transmit to each receiving station. On the other hand, before the scanning of all the originals 5 is completed, that is, when the number of originals is n, the number of originals 5 is k.
If the storage capacity of the storage unit 15 overflows during scanning of (k <n), an overflow signal is output from the storage unit 15 to the control unit 18. When the control unit 18 processes the overflow signal, the operation of the drive unit 20 is stopped and the supply of the document 5 is stopped. At the same time, under the control of the control unit 18, the stored contents of the (k-1) th original document 5 stored in the storage unit 15 are sequentially transmitted to a plurality of receiving stations based on the above-described operation. When the document transmission to each of the plurality of receiving stations is completed, the drive unit 20 is operated by the control unit 18,
The supply of the original 5 starts again. When the supply of the original 5 is restarted, the kth to nth originals are scanned, and the contents are stored in the storage unit 1.
5 is written in order from the top address to the lower address (therefore, the first half of the kth document is written at the end of the address, and the second half of the kth document is written from the top address). When the writing to the storage unit 15 is completed, it is transmitted to the plurality of receiving stations designated by the above-described operation.

As described above, according to the facsimile broadcasting apparatus of the present invention, when the stored document information reaches the predetermined storage capacity level, the reading of the document is interrupted and the document information is transmitted to the designated receiving station. Since the reading of the original is resumed after that, the operability can be improved because the transmission can be performed even when the transmission information increases due to the increase in the number of originals or the high density of the original contents.
