Abstract

PURPOSE:To improve the practicality of the facsimile equipment which can read both the surfaces of a document by informing an opposite receiver of a both-sided document and sending the document in the order of the top surface and reverse surface. CONSTITUTION:When it is judged that the opposite receiver can perform both- sided recording, the opposite side is informed that a next page is the top surface by using an NSS signal. The document top surface is read and encoded by a read circuit 10 and an encoding circuit 14, and sent. The document reverse surface is read through a read circuit 12 and an encoding circuit 16, and stored in a memory circuit 18. After one page is read, it is indicated that a next page is the reverse surface by using a procedure signal, and a signal level 1 is outputted to a signal line 46e to make a modulator 22 ready to input a signal from a signal line 20a. Then the information stored in the circuit 18 is encoded and sent through signal lines 46c and 46d. Consequently, the opposite receiver is informed of the both-side document and the document is sent in the order of the top surface and reverse surface to improve the practicality.

According to the present invention, in a facsimile apparatus capable of reading both-sided information of original information, a notifying means for notifying a partner receiver that it is a two-sided original, and a two-sided original for front and back sides. And a transmission means for transmitting the data in order.

Further, according to the present invention, in a facsimile apparatus capable of reading both-sided information of original information, a two-sided original is transmitted in the order of front side and back side, and a single-sided original is transmitted only to the front side, and a receiver. It is characterized in that it has a notifying means for notifying whether a single-sided original or a double-sided original is being transmitted.

When reception is selected in S62, a signal of signal level "1" is output to the signal line 46a in S108, the CML is turned on, and in S110, a counter for counting the number of double-sided pages. Set 0 to. Further, in S112, 0 is set to the counter that counts the number of one-sided pages.

Then, in S114, the pre-procedure is executed. Here, the other side transmitter is notified that double-sided recording is possible, and the side (front side or back side) of the next page from the other side is stored.

Next, in S116, it is determined whether the recording is a front surface instruction or a recording without any instruction. Then, when recording the front side instruction or no instruction, the process proceeds to S118, and when recording the back side instruction, S118 is performed.
Proceed to 134.

In S118, the signal of the signal level "1" is output to the signal line 46f, and the recording circuit 32 performs recording on the recording paper surface A (front surface).

Then, in S120, it is determined whether or not the reception of one page is completed. When the reception of one page is completed, the process proceeds to S122. If the reception of one page is not completed, the process returns to S118.

At S122, an intermediate procedure is performed. Here, the surface (front surface or back surface) of the next page is stored.
Next, in S124, it is determined whether or not the next page is transmitted, and if the next page is transmitted, the process proceeds to S130,
If the next page is not transmitted, the process proceeds to S126, and since the page is a one-sided page, the one-sided page counter is incremented by one. Next, in S128, a post-procedure is performed, and S52
Return to.

Further, in S130, it is determined whether or not the back side information is present. If there is no front side information or side direction, the process proceeds to S132, and since it is a single sided page, the single sided page counter is incremented by one. If it is the back side information, the process proceeds to S134.

In S134, the signal of the signal level "1" is output to the signal line 46e, and the recording circuit 34 performs recording on the recording paper surface B (rear surface). Next, in S136, it is determined whether or not the reception of one page is completed. When the reception of one page is completed, the process proceeds to S138, and since it is a double-sided page, the double-sided page counter is incremented by one. If reception of one page is not completed, S134
Proceed to.

In S140, the signal on the signal line 42a is input, and when the signal level is "1", that is, when the original is a double-sided original,
It is determined whether or not the stamp pressing of the double-sided original is selected. When the stamp pressing is selected, the signal line 4
A stamp pressing pulse is generated at 6i, a stamp for a double-sided original is pressed through the stamp pressing circuit 36 (S142), and the process proceeds to S144. If the stamp pressing is not selected, the process directly proceeds to S144.

At S144, an intermediate procedure is performed. here,
Memorize the side (front side or back side) of the next page. next,
In S146, it is determined whether or not there is a next page.
Then, when there is a next page, the process returns to S116, and when there is no next page, the process returns to S128.

In the first embodiment described above, when double-sided recording is performed on the receiver side, it is considered that the front side stamp is pressed at the time of selecting to record that fact. However, according to the character string information, for example, "two-sided original" may be recorded. Specifically, in S142, the command pulse is generated on the signal line 46h instead of generating the stamp pressing pulse on the signal line 46i.

As the communication result report and the communication management report on both the transmitter side and the receiver side, the total number of communication pages (the above-mentioned page counter) and its breakdown, that is, the number of pages of one-sided information (the above-mentioned one-sided page counter), both sides The number of pages of information (double-sided page counter) may be recorded.

In the first embodiment, direct communication is considered. However, it may be applied to memory transmission. In this case, in the pre-procedure, when the receiver can perform double-sided recording, one side or both sides of the previous page to be communicated may be notified prior to the transmission of the image information. At the receiver, recording is facilitated by obtaining this information before starting recording. That is, if only a single-sided original is used from the beginning, recording becomes easy and double-sided stamping becomes easy.
