Abstract

PURPOSE:To minaturize a copy transmitter, by detecting the receiving/recording state of a receiving device and then delivering this receiving/recording state in the form of a communication history. CONSTITUTION:The picture information is transmitted to a terminal R from a terminal Q for the polling given from a private exchange PABX 1. In such a case, an instruction packet of transmission request is sent to the PABX 1 from the terminal Q. Receiving this instruction packet, the PABX 1 switches a rotary switch of the exchange 4 to select the terminal R and transmits a signal ACK to the terminal Q to inform that the terminal R is detected. Then the terminal Q detects the transmitting conditions including the size, the number of sheets, etc. of originals as well as the recording state of the terminal R. Then a communication history is produced and sent to the terminal Q when the terminal R is busy.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying and transmitting apparatus, and more particularly, to a copying and transmitting apparatus that detects a reception recording state on a receiving side and outputs the reception recording state as a communication history.

A typical example of a conventional image transmission device is a facsimile that uses a public telephone line. Additionally, similar systems are being set up privately as part of the rationalization of office work. for example.

- Within a company, each department is provided with a terminal device that can send and receive image information, and these terminal devices are connected via a unique line to send and receive image information between each department.

When trying to send image information from one terminal to a desired terminal using such a communication system, the receiving terminal may fail and the two terminals cannot be connected.1 The line may be blocked or a jam may occur. If you type
That is, if the receiving terminal is not in a state where it can receive data, it may be possible to display a warning to that effect on the transmitting terminal. However, the time it takes for the receiving terminal to return to a receiving state is uncertain depending on the cause, and simply issuing a warning does not allow the operator to constantly monitor the terminal for recovery and perform the same operation again. Need to repeat. In addition, when transmitting the same document to multiple terminals, if a terminal is not receiving the data normally, it is necessary to notify the sending side, so a warning is required for each terminal, and the display device etc. There is a fear that it will become a big deal.

FIG. 2 shows an example of signal exchange between the PABX/ and each terminal, for example, terminals Q and R. Here, terminal Q is the third
The reader JA and printer 3A shown in the figure are assumed to be reader JA, and the terminal R is assumed to be reader B and printer 3B. First, PABX
/ sends polling to terminal Q, and when there is no information to be sent from terminal Q, a command packet indicating no request is sent to PABX/. Next, PABX
/ sends polling to terminal R. When there is no information to be sent, a command packet without a request is similarly sent to the PABX/.

Now, it is assumed that M3 manuscript is read on terminal Q, that terminal R has the completed paper of A, and that terminal R's line is free and everything is normal. Figure 7
The present invention will be explained with reference to the 0-chart and the procedure of transmitting and receiving signals in FIG.

Note that the case where only one image is transmitted will be explained first.

When image information is to be transmitted from terminal Q to terminal R in response to polling from PABX/ (procedure P/), that is, in procedure Q/ in terminal Q, the start key for the transmission mode is pressed. In this case, a command packet of a transmission request indicating that there is information to be transmitted from terminal Q to terminal R is sent from terminal Q to PABX/5 (procedure Q). In response to this, PABX/ performs security to select terminal R in one step. That is, the rotary switch R8Wj of the exchanger≠ is switched to the f contact. The selected terminal R checks the printer 3C in step R/, and displays A indicating the result of the check and the fact that it has been selected.
OK (acknowledge) signal to PABX/
It is sent to terminal Q via .

Check the contents in step P3, and for terminal Q#,
A request is made to detect transmission conditions such as the size and number of originals to be transmitted. Next, in procedure P$, terminal R
determine whether it is normal or not. For example, if terminal R is occupied by another transmission request, that is, if it is busy, a negative determination is made in step p4A, and step P! At this point, a communication history called an error list shown in FIG. 73 is created.

On the other hand, based on the request in step P3, the terminal Q detects the size of the document to be transmitted and the number of copies.

Here, the document size can be set by the operator using the document size entry key (
(not shown) or by optical detection. In step P6 of PABX/, the transmission conditions are checked and the transmission information is sent to terminal R.
Send to. In step R of terminal R, the paper size loaded in the printer 3B of terminal R is detected and the detected information is sent to the PABX/ as a mu OK signal.

In step P7 of PABX/, the document size and the recording paper size are compared and determined, and it is determined by hand@PI whether or not it is necessary to scale the image information transmitted from the terminal Q. Now, since the A3 version manuscript is to be recorded on AJ version recording paper, an affirmative judgment is made that the scaling is changed, and the process proceeds to step P. In step P, a mis read request is sent to terminal Q using an AOK signal. In step Q4t, the terminal Q reads the original image in response to the request and inputs the image information into the page memory j of the PABX/ (
Step P10').

Determine whether or not it is necessary to change the magnification in step P//.

In step P/co, the image information in page memory j is multiplied from the 3rd edition to the ginseng edition. In step P/J, it is determined that terminal R is normal, and in step P/4C, the scaled image data is transmitted to terminal R. At the terminal R, in step R3, it is determined whether the terminal R is normal or not, and therefore, in step R, the variable-magnification image information is received and recorded. Next, in Step 5 Rj, the printer 3B is checked, and in Step R6, it is determined whether the printer is normal. Since this is normal, it is determined in step R7 whether a predetermined number of sheets have been received and recorded. Since only one sheet is recorded, an affirmative determination is made and the process ends in step Rr. When recording a plurality of sheets of the same original, a negative determination is made in step R7, and the variable-magnification image data is received again from the disk 6 of the PABX/ in step R4I. Also, the detection information of procedure Rj is transmitted to PABX/.

Since terminal R is detected as normal by hand JI Pat,
Step P/A to Step P/? The process proceeds to step Pit, where the end of the series of operations of terminal Q and terminal R is detected in steps Qj and Rr, respectively, and step P/? This completes the series of transmission operations.

Next, read the M3 version manuscript and send it to terminal R, which is the destination.
The case where the third edition recording paper is loaded and the line of terminal R is busy will be described with reference to FIG. 1O.

The steps up to step P≠ are executed in the same manner as described above, and a negative judgment is made in step 1, and step P! In this step, an error list shown in FIG. 73 is created. Further, a negative determination is made in one step PI, and a further negative determination is made in step Pr. In step P, a request is made to the terminal Q to read the picture book, and in step P10, the image information read in step Q4I is once input into the page memo IJj. Next, a negative determination is made in step P//, and the process proceeds to step P, where the image information is stored on the disk basis.

In step P-, a request is made to terminal R to detect whether or not the line is free. At terminal R, procedure R has already been performed.
3, an abnormality in the terminal is detected, and therefore, in step R, the printer is checked in response to the request. now,
When the line becomes free, a notification to that effect is transmitted to the PABX/. However, an affirmative judgment is made in step 1 RL7, and step P2
1! Then, the image information on the disk 6 is transmitted to the terminal R, and the image information is received and recorded in step R10. The following steps are the same as those described above.

A case will be described in which a third edition document with missing numbers is read, AJ edition recording paper is loaded in terminal R, and one line is not busy but normal. In this case, the process proceeds from step Pt to step P through step P〃, and requests the terminal Q to read 5 images. Next, in step P2A, the transmitted image information is transmitted to the terminal R in real time, and the reception of the terminal R is recorded in step R ζ. In this case, PA
The state of signal exchange between BX/ and terminals R and 9 is shown in Figure 1.

Next, a case will be described in which three sheets of the same original are to be transmitted, and an abnormality occurs in the line of Gosaiko terminal R, which has received and recorded normally up to the second sheet. In this example, every time terminal R receives and records one sheet, the printer is checked in step R1, and the printer becomes ready to receive in step 1flR1 after receiving and recording the λth sheet. It is determined that there is no terminal, and the process proceeds from step R4 to step RIr, where the series of operations of terminal R ends. On the other hand, in PABX/, a negative determination is made in step P/4, and an error list is created in one step P core. For example, it can be recorded as shown in the second line of FIG.

Give an example. In the figure, "filem" indicates the registration number on disk 6, and by specifying this number, the quest keyta shown in FIG. 1 is recorded. By operating , you can output the list shown in this figure. "Size" indicates the size of the iijigl information saved on disk 4, "Size" indicates the specified number of copies to be sent, and "Size" indicates the receiving recording status, indicating whether the data has been received normally. Indicates the number of images recorded. Please note that each item, title, frame and broken line have been prepared in advance by PA.
It is assumed that it is stored in the memory of BX/. Therefore,
When a request is received from each terminal, the communication history shown in this figure is created in the page memo IJj and sent to each terminal as image data.

As explained above, according to the present invention, the reception record state of the receiving device can be detected and the reception record state can be output as a communication history, so a warning is sent to the transmitter side to inform the transmitter of an abnormality in the transmission record for each terminal. Output □ Device 1 For example, there is no need to install a warning light, and the display device etc. can be downsized, contributing to cost reduction of the device. Furthermore, by outputting the specified number of transmitted sheets and the number of sheets actually transmitted and recorded as a communication history, it is possible to easily know the number of sheets that could not be transmitted and recorded due to an abnormality in the receiving device during recording.
