なる欠点があつた。(b) Prior Art and Problems Facsimile machines (hereinafter referred to as FAX) have different communication means depending on their model. Additionally, it is equipped with a means for outputting two types of sizes (A4/B4) with one device. Therefore, the transmitting side sends a signal inquiring about the receiving side's communication method (standard/non-standard), and after receiving a response signal, the receiving side
Sends image data using a method compatible with fax.
Note that as the 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 faxes prior to sending the image data. In such a facsimile system, when a FAX without a response means is installed on the receiving side to perform one-way communication, the sending FAX only sends out a confirmation signal unilaterally. In such unidirectional communication, there is a drawback that when the document size information does not reach the receiving side, the receiving side's fax cannot receive it.

を特徴とするフアクシミリ装置である。(d) Configuration of the Invention The present invention includes a transmitting device that transmits compressed image data in line units, a line end signal, and document size information;
In a facsimile system in which means for outputting received manuscripts of at least two different manuscript sizes and a receiving device having a decoding unit are connected by a line, a determining means for determining whether or not the manuscript size information has been received;
comprising a counting means for counting decoded image signals from the decoding unit, and an output means for outputting the decoded image signal in a document size corresponding to the count value by the counting means, when the document size information has not arrived, The facsimile apparatus is characterized in that it counts the number of decoded image signals from the decoding section and outputs image information of a document size corresponding to the counted value.

合に生ずる受信不能を、防止することができる。 As described above, the present invention enables a facsimile machine (receiving side fax) that does not have a response means to process the transmitted original by counting the number of received image data (bits) even when the original size information cannot be received from the sending side. It is equipped with a means for determining the size. Therefore, it is possible to prevent the inability to receive the document size information that occurs when the document size information has not arrived.

In the drawing, sending side FAX1 and receiving side FAX2
and is connected by line 3. Sender fax
1 and the image data G in the image memory 4 are taken out for each line unit data G 1 to Gn, compressed in the transmitter 5, and become compressed data G', a line end code EOL is added to this, and the line is sent to the line. 3. Therefore, the signal S on the line is as shown in the figure.
Compressed (line by line) data G 1 ′, line termination code
Data is transmitted in the following order: EOL 1 , compressed (line unit) data G 2 ′, line end code EOL 2 . . . . Note that prior to sending out this signal S, the transmitting section 5 sends document size information Z to the receiving side FAX 2. Receiving fax
2 does not have a means to send a response signal corresponding to this document size information Z, so the sending side FAX 1
From then on, image data (signal S) will be sent out.

Information specifying B4 size) Z is stored in the reception buffer 7. The determining section 8 determines this received information Z, and sends a signal A4 to the output section 9 when the size is A4, and a signal when the size is B4. Therefore, the output section 9
From there, an A4 size original 10 or a B4 size original 11 is output. The above is a normal case, and if the document size information Z has not arrived, the reception buffer 7 immediately receives the signal S. The determining unit 12 determines the line termination code in the receiving buffer 7.
When EOL is detected, a control signal C is issued to start the counter 13. Accordingly, the number of decoded image signals (for example, G 1 ') decoded by the decoding section 14 is counted by the counter 13.

Ｇを、A4判又はB4判の原稿として出力する。 The determining unit 15 checks the count value of the counter 13, and when the value is 1728 (bit), it determines that the size is A4 and outputs a size signal A4 , and when the value is 2048 (bit), it is determined that the size is B4. It discriminates and outputs a size signal B4 . Therefore, the output section 9 outputs a signal A 4 specifying this size.
Or, depending on B4 , the restored image signal G in the buffer 16 is output as an A4 size or B4 size original.
