Abstract

PURPOSE:To make it possible to receive picture data even if original size information is not received yet, by outputting original size information corresponding to counted decoded picture signals if original size information is not received yet in a facsimile system. CONSTITUTION:If original size information Z is not received yet, a signal S is received by a receiving buffer 7, and a discrminating part 12 generates a control signal to start a counter 13 when a line end code EOL in the receiving buffer 7 is detected. The number of decoded picture signals decoded by a decoding part 14 is counted by the counter 13. A discriminating part 15 checks the counted value of the counter 13 and discriminates A4 size when this value is 1,728 bits and discriminates B4 size when it is 2,048 bits. An output part 9 outputs decoded picture signals G in a buffer 16 as signals of an A4 or B4-size original in accordance with this discrimination signal. Thus, even if information designating the original size does not reach the reception side, normal reception of FAX is possible.

Description

Detailed Description of the Invention (a) Technical Field of the Invention The present invention relates to a facsimile machine that does not have a means for responding to information from a sender. ), the communication means differ depending on the model. Furthermore, it is equipped with a means for outputting two types of sizes (A4/B4) with one device.

Therefore, the transmitting side sends out a signal that adjusts the reverse method (standard/non-standard) on the receiving side, and after receiving a response signal to this signal, it sends out image data in a method corresponding to the receiving side FAX. 1. As a confirmation signal, document size information specifying the output paper size of the image data is also sent. In this way, confirmation signals are exchanged between the sending and receiving FAX machines prior to sending the image data. In this way, in facsimile systems, faxes that omit the response means,
When installed on the receiving side for unidirectional communication, the transmitting side F
A confirmation signal is only sent unilaterally from AX. In such unidirectional communication, there is a drawback that when the document size information does not reach the receiving side, the receiving side FAX cannot receive it.

(C) Purpose of the Invention The present invention has been made to solve the above-mentioned drawbacks.
This is a facsimile machine that allows image data to be received even if image data has not been received.

(d) Structure of the Invention The present invention includes a transmitting device that transmits compressed image data in units of bamboo, a line end signal, and document size information, and at least two
In a facsimile system in which a means for outputting a received original of a type 1 original size and a receiving device having a No. 4 part are connected by a line, a determining means for determining whether or not the original size information has been received, and a former T3 self. A counting means for dividing the decoded image signal from the number part, and an output means for outputting the previous dpi decoded image signal with the original size corresponding to the count number by the dividing means, and the previous Ma original size information is The facsimile apparatus is characterized in that when a call is not received, the number of decoded image signals from the pick-up code section is counted, and image information of a document size corresponding to the counted value is outputted.

2. The number of image data (bits) received by a facsimile machine (receiving side FAX) that does not have a response means even if document size information cannot be received from the sending side. This is an additional means for determining the size of the transmitted original by counting the number of digits. Therefore, the unreceivable situation that occurs when the original size information has not arrived,
It can be prevented.

(e) Examples of the invention The present invention will be explained below with reference to the drawings. The drawings are professional diagrams for explaining one embodiment of the present invention.
The sending side FAX1 and the receiving side f1+1FAX2 are connected by a line 3. Image data G in the image memory 4 of the sending FAXI, line middle data (G+-G
n), and is compressed in the transmitter 5 to become compressed data d. A line end code EOL is added to this, and the data is extracted every time #f! Sent to 3. Therefore, as shown in the figure, the signal S of line-hi is compressed (line unit) data 01'
, line end code EOL I + compressed (line coronation) data G2', line end code EOL2...
Send data in this order.

Note that, prior to sending out this signal S, the transmitting section 5 sends the original size 3 - size tII + T'142 f to the receiving side FAX 2. Since the receiving side IF'AXI;t has a means to send out a response signal corresponding to the original size 1 and 2, the sending side FAX 1 subsequently sends the image data ( Signal S) is sent out, often.

On the receiving side WAX 2, the document size information (information specifying the document size as A4 size or 04 size) received by the receiving unit 6 is stored in the reception buffer 7. The discriminating section 8 discriminates this received information (Z) and sends a signal -'i+A4 to the output section 9 when the size is A4, and a tzu signal when the size is 04. Therefore, the output section 9 outputs rl: A4 size original 10 and 04 size original 11. The above is a normal case, and if the document size information Z has not arrived yet, the reception buffer 7 immediately receives the message -@S.

The determining unit 12 determines whether the line terminal mark in the buffer 7 is *:
When EOT is detected, a control signal C is issued to start the counter 13. Accordingly, the number of decoded image signals (for example, G1') decoded by the decoding section 14 is counted by the counter 13.

4- Check the count value of the discriminator 15 counter 13 and check if the value is 1.
, 728 (bit), it is determined that the size is A4, and the size signal A4 is output, and the value is 2,048 (bit).
If so, it is determined that the size is 04, and a size signal B4 is output.

Therefore, the output unit 9 outputs the restored image signal G in the buffer ]6 to A4 in accordance with the signal A4 or B4 specifying the size.
Output as a size or 04 size original.

(f) Effects of the Invention As described above, the present invention has the advantage that, in a facsimile system using a cross-directional communication method, even if the information specifying the document size does not reach the receiving side, the receiving side can receive the fax normally. has.
