If there is a detection signal related to , the system switches to the second mode in response, stores the information in the storage means, reads it after storage, and records the information on the recording material, so even if the recording material no longer exists, ↑ ? It is possible to send signals smoothly.

[Industrial application field]

The present invention relates to an information receiving system, and more particularly, to an information receiving system for obtaining a hard copy based on a received information signal using, for example, a facsimile machine.

[Conventional technology]

For example, in a known facsimile machine that uses an information receiving system, when receiving recording paper, there are cases where the recording paper runs out even when reception is in progress.

In such a case, an end mark without paper is detected. Therefore, the receiving facsimile machine sends an RTP (a control signal indicating that the message was received correctly but training is required) to the sending facsimile machine, and the receiving side disconnects the line and sends a message to the sending facsimile machine. ”. Also, on the transmitting side, NSS (command in response to NSF) and TCP signals are repeated. CFR (receiving preparation signal indicating that it is okay to start sending a message)
The line was disconnected due to a timeout while waiting for the message to be returned.

After that, the receiving side waits for recording paper to be replenished, and both facsimile machines are turned on for communication, and the unreceived information is retransmitted.

[Problem that the invention seeks to solve]

However, in a facsimile machine using such a conventional information receiving method, each time the receiving side runs out of recording paper (state of no recording paper S), the transmission and reception of information must be temporarily interrupted and then retransmitted. However, there have been problems in that the facsimile machine is troublesome to operate and is inefficient in transmitting and receiving information.

The present invention was created in view of these points, and eliminates the need to temporarily interrupt and retransmit information every time the receiving side runs out of recording paper (no recording paper left). It is an object of the present invention to provide an information receiving method that has good operability and can efficiently transmit and receive information.

[Means for solving problems]

FIG. 1 is a principle block diagram of the information receiving system of the present invention.

In the figure, the reception method selection means 119 selects the information signal 11
1 is received and directed as a received record information signal 115 and a stored information signal 117 in response to a selection signal 113.

The storage means 121 receives the storage information signal 117 and stores the information.

The recording control means 129 receives a readout signal 123 . of the information stored in the storage means 121 . Any one of the received recording information signals 115 is transmitted to the recording information signal 12 in response to the recording control signal 125.
Set it to 7.

The recording means 133 records the information on the recording material 131 in accordance with the recording information signal 127.

The detection means 137 acquires information related to the presence or absence of the recording material 131 and outputs a detection signal 135 in accordance with the information.

In the first mode, the control means 139 outputs a selection signal 1.

1 as the storage information signal 117 and controls the storage means 121 to store the information. Furthermore, even during operation in the first mode, it is possible to switch to the second mode in response to the detection signal 135.

Therefore, as a whole, in the first mode, the recording material 13
1 no longer exists, the mode is switched to the second mode, the information is stored in the storage means 121, and after being stored, it is read out and recorded.

[For production]

In the first mode, the information signal 1 is controlled by the selection signal 113 and the recording control signal 125 from the control means 139.
11 becomes the received recording information signal 115, and the recording information signal 1
27, information is recorded on the recording material 131.

In the second mode, the information signal 111 is stored in the stored 1n information signal 117 in accordance with the selection signal 113 from the control means 139.
The information is then directed to the storage means 121 and the information is stored in the storage means 121.

If the recording material 131 no longer exists in the first mode, the mode is switched to the second mode and the information is stored in the storage means 121,
Read and record after storing.

In the present invention, even in the first mode of operation, when the recording material 131 is no longer present, the mode is switched to the second mode in response to the detection signal 135, and the information signal 11 is stored in the storage means 121.

Even during reception and recording of 1, information can be smoothly received by storing subsequent information once and recording it later.

[Embodiments of the invention]

Next, embodiments of the present invention will be described in detail based on the drawings.

FIG. 2 is a configuration block diagram showing an information receiving system according to an embodiment of the present invention.

■, and 1゛... - Here, the correspondence between the main elements in FIG. 1 and the main components in FIG. 2 will be explained.

The information signal 111 in FIG. 1 is connected to the public telephone line 21 in FIG.
This corresponds to the received information transmitted via 1.

Further, the reception method selection means 119. recording control means 129;
The control means 139 includes a line control unit 213゜modem zts,
It corresponds to the i reduction/restoration section 217 and the main control section 219.

Furthermore, the storage means 121 is connected to the file storage section 221, the recording means 133 is connected to the recording section 223, the detection means 137 is connected to the recording paper state detection section 225, and the control means 139 is connected to the main control section 219.
In addition, the recording materials 131 correspond to recording sheets (not shown) included in the recording section 223, respectively.

Regarding signals, the detection signal 135 is the recording paper detection signal 227.
, the recording information signal 127 becomes the recording signal 229, the storage information signal 117 becomes the file accumulation signal 231, and the read signal 12
3 corresponds to the file read signal 233, respectively. Selection signal 113, which is another signal. Reception record information signal 11
5 and the recording control signal 125 are both sent to the main control section 219.
This corresponds to the control signal within.

Examples of the present invention will be described below assuming that such a correspondence exists between ■, , and Φ.

The configuration shown in FIG. 2 is assumed to be a facsimile machine,
This facsimile device serves as a receiving end and is connected to another facsimile device via a public telephone line 211 so that information can be sent and received.

When the facsimile machine is in a receiving state, information signals transmitted via public telephone line 211 are received by line control section 213 controlled by line control signal 235 supplied by main control section 219. The received signal 237 is converted by the modem 215, and the converted signal 239 is data restored by a data restoration circuit of the compression/decompression section 217. The restored data signal 241 is output by the main control unit 219 as a recording signal 229 in the recording mode and as a file accumulation signal 231 in the file mode.

If the present facsimile apparatus is in the recording mode and recording paper is present, the information represented by the recording signal 229 is recorded by the recording section 223 on the recording paper. However, if there is no recording paper even during operation in the recording mode, the recording paper type B detection section 225 supplies a recording paper detection signal 227 to the main control section 219.

Further, in the file mode, if the file capacity of the file storage section 221 in which information is to be stored is sufficient, the information of the restored data signal 241 is stored in the file storage section 221.

During the operation of receiving and recording information in the recording mode, if the recording paper ends and the recording paper detection signal 227 is generated,
The main control unit 219 stores the restored data signal 241 in a file, reads out the information as a readout signal 233 after receiving all the information, and records the information again after the readout signal 233 is replenished with recording paper.

The above is the overall operation of this embodiment. Next, the operation will be explained with reference to the control procedure.

Figure 3 is a flowchart showing the operation order of the recording mode and file mode in the embodiment of the present invention.

In FIGS. 2 and 3, the configuration shown in FIG. 2 is used as a receiving side facsimile machine, and a not-shown facsimile machine connected by a public telephone line 211 is used as a transmitting side. All facsimile machines are G3 (high speed) 81 types.

The transmitting side listens to the CED (called station identification signal) from the receiving side and switches to facsimile, and the receiving side sends back a signal (DIS) indicating its function and enters the reception start state (step 311).

In the facsimile machine on the receiving side, a lamp indicating that it is in a receiving state is lit (steer knob 312).

Under the control of the main control unit 219 of the facsimile machine on the receiving side, it is determined whether the receiving mode of the facsimile machine is the file mode (step 313).

Assume that you are now in recording mode. Step 3
A negative determination is made in step 13, and it is then determined whether or not there is recording paper in the recording section 223 (step 314). This determination is made depending on whether an end mark with no recording paper is detected. If there is recording paper (affirmative determination), the main control unit 219 moves to the data recording operation from step 315 onwards.

First, the message data sent from the sender via the public telephone line 211 is compressed/decompressed by the compression/decompression unit 217.
The data is restored by the data restoration circuit (step 315).

Restored data signal 2 obtained by compression/decompression section 217
41 is outputted by the main control unit 219 as a recording signal 229,
Step 316: The recording unit 223 records information on recording paper.
), determine whether one page of the sent document is completed (
step, 317).

If the process has not ended (negative determination), the process returns to step 315.

The above loop operation is repeated, and when an affirmative determination is made in step 317, the loop is removed and one page is recorded.

After one page has been recorded, the presence or absence of recording paper is determined again (step 318). This determination is made in the same manner as step 314.

If recording paper exists (affirmative determination), then it is determined whether there is still a document to be sent (received) (step 3).
19) This determination is made based on whether or not an EOP (a control signal indicating the end of one page and indicating that there is no continuous transmission) has been received from the transmitting side. If EOP is not received, there is a next page (affirmative determination), so step 31
Return to step 5 and repeat the above operations. On the other hand, E
○If P is received, there is no next page (negative judgment)
, ends the recording mode operation.

■, φ in file mode Next, let's see how it works in file mode.

If the facsimile machine has been designated as file mode from the beginning, an affirmative determination will be made in step 313.
The process moves to the file mode operation from step 320 onwards.

Further, if there is no recording paper even during operation in the recording mode, the recording paper state detection unit 225 outputs a recording paper detection signal 227 indicating that there is no recording paper. Therefore, in response to the recording paper detection signal 227, the main control unit 219 performs execution control to similarly shift to the file mode operation in steps 314 and 318.

In step 320, in response to the main control unit 219, the file capacity detection unit 243 determines whether the file capacity in the information storage means included in the facsimile machine is sufficient.

If the file capacity is sufficient (tt definite determination), the data is restored by the compression/restoration unit 217 (step 321).
) The main control unit 219 returns the restored data signal 241 to the data compression circuit of the compression/restoration unit 217 and compresses the data again (step 322 ), and the compressed data is output as the file storage signal 231 .
The compressed data is stored at (step 323). Next, it is determined whether one page of information to be stored has been completed (step 324). If not completed (negative judgment),
Returning to step 321, the above-described data storage operation is repeated.

When the storage for one page is completed, it is determined whether there is any more information to be stored (step 325). This determination is also made in the same manner depending on whether the EOP is not received or received. If there is a next page (affirmative determination), the process returns to step 320 and continues the data storage operation. If all pages are completed (negative determination), the file mode operation ends.

The above is the operation of recording the transmitted information from the sending facsimile machine on recording paper or filing it in the receiving facsimile machine.

(2) File output mode Next, recording of data filed by the facsimile machine will be explained.

This file output mode is an information recording mode similar to the recording mode, and is not recording of received data but recording of file data.

FIG. 4 is a flowchart showing the operation sequence in the file output mode in which data stored in the file storage section 221 is recorded. Reference will now be made to FIGS. 2 and 4.

The main control unit 219 controls the facsimile machine to perform operations in the file output mode.

In this file output mode, first, the recording paper state detection section 225 determines whether or not there is recording paper in the recording section 223 (step 411).

If there is no recording paper (negative determination), the file output operation waits until recording paper is replenished.

If recording paper exists (affirmative determination in step 411),
Next, the main control unit 219 extracts the data stored in the file storage unit 221 (step 412), and reads the read signal 2.
33 is supplied to the data restoration circuit of the compression/decompression section 217. The compression/decompression unit 2'' 7 restores the compressed and stored data and sends it to the main control unit 2 as a restored data signal 241.
19 (step 413).

The main control unit 219 outputs data as a recording signal 229 in the same manner as the recording operation in the recording mode. Similarly, the recording unit 223 also records information on recording paper (step 41
4).

Thereafter, it is determined whether recording of information for one page has been completed (step 415), and if it has not been completed (negative determination).
, the process returns to step 412 to record data for one page.

When data recording for one page is completed (step 415)
(affirmative determination in step 416), it is determined whether there are any more pages to be recorded (step 416). If there is a next page to be recorded (affirmative determination), it is determined whether there is still recording paper in the recording section 223 (step 417). If there is recording paper (affirmative determination), the process returns to step 412. Information about all pages - records.

■, Note 2 in #2 mode Φ In this way, when recording data on the receiving facsimile machine, even if the recording paper runs out, you can switch from recording mode to file mode and record the received data as is. Since the information is stored and data is recorded in the file output mode after the recording paper is replenished, there is no inconvenience in receiving information due to the end of the recording paper.

In the above-described embodiment, data was compressed and restored in the file mode and file output mode in order to increase data storage efficiency in the file storage section 221, and the restored data signal The data of 241 may be filed as is and stored in the file storage section 221, and the data of the read signal 233 may be recorded as is in the recording section 223.

Furthermore, although the configuration of the embodiment has been described in relation to FIG. 1 in "■. Correspondence between the embodiment and FIG. 1", it goes without saying that there are various variations B.

〔Effect of the invention〕

As described above, according to the present invention, even if there is no recording material during reception recording, the communication status between facsimile machines is not interrupted (recording can be obtained). It is extremely useful in practical terms.
