Description

The present invention relates to a facsimile system.

(B) Conventional technology In recent facsimile machines, a plurality of telephone numbers of communication destinations are stored in correspondence with one-touch keys, and upon transmission, the original telephone number is stored after setting a document. By simply operating the selected one-touch key, a dial is automatically transmitted, a response from the other party's facsimile apparatus is detected, and transmission is automatically started (for example, see Japanese Patent Application Laid-Open No. 60-96951). .

(C) Problems to be Solved by the Invention Since transmission is performed automatically with one touch as described above, if a wrong one-touch key is operated by mistake, it will be transmitted to another facsimile machine, and the user must be careful. It was necessary to operate the one-touch key while paying. In addition, even if the user confirms the destination displayed on the display during transmission and notices that the message is being sent erroneously and performs a stop operation, especially for the contents that have already been sent, the other party's facsimile machine records the reception and outputs it. However, there is a problem that the transmission contents are read by a third party.

(D) Means for Solving the Problems The present invention has been made to solve the above-mentioned problems.
The transmitting facsimile apparatus has means for reading and transmitting a transmission original, and means for instructing reception recording. On the other hand, the receiving facsimile apparatus has a memory means for storing received contents, and a memory means for receiving a reception recording instruction signal. The recording means is configured to control the recording of the data stored therein.

(E) Operation Since the present invention is configured as described above, the contents of transmission are stored in the memory on the receiving side, and the receiving record is recorded only when the transmitting side confirms that there is no error in the transmission destination and instructs the receiving record. If you notice an erroneous transmission in the middle of the transmission, if you do not give an instruction to record the reception, the receiving side will not record the reception at all, so even in the case of an erroneous transmission, the contents of the transmission can be read by a third party Nothing.

A control circuit (3) which receives a key signal performs control in accordance with a control program according to the key signal. A display (10) displays data input from the keyboard (9), data processed by the control circuit (3), and the like, and is constituted by a liquid crystal display. A modem circuit (11) modulates a signal transmitted to the telephone line (L) and demodulates a signal from the telephone line (L), and is connected to the line switching circuit (12). (1
A dial signal generating circuit 3) generates a pulse or tone dial signal based on the telephone number data supplied from the control circuit 3, and is connected to the line switching circuit 12. The line switching circuit (12) is composed of a model circuit (11), a dial signal generation circuit (13), and a relay circuit for switching and connecting the telephone (14), and is controlled by a control circuit (3). Also, this line switching circuit (12)
An incoming call detection circuit that generates an incoming call detection signal by detecting an incoming call bell signal is incorporated.

 Next, the operation of the present invention having such a configuration will be described.

First, in the dial memory (8), telephone number data of a communication partner to be frequently communicated is input by a predetermined key operation of the keyboard (9), and each telephone number corresponds to a one-touch key of the keyboard (9). The stored telephone number data is read out by operating the one-touch key.

 Next, the transmitting operation will be described.

The original to be transmitted is set on the reading section (4), and the step (S20
When the one-touch key indicating the transmission destination of the keyboard (9) is operated in 1), the control circuit (3) that detects the key signal outputs
After the line switching circuit (12) is controlled to close the line in step (S202), the telephone number data corresponding to the operated one-touch key is read out from the dial memory (8) and supplied to the dial signal generation circuit (13). I do. The dial signal generation circuit (13) which has received the telephone number data generates a preset pulse or tone dial signal in step (S203), and transmits the telephone line (L) via the line switching circuit (12). Make a call to. The fact that the receiving-side facsimile machine (2) has responded to the dial transmission in step (S204).
The control circuit (3) detected in (1) proceeds to step (S206) to perform communication of a predetermined control signal with the receiving side, and then proceeds to step (S207) to control the reading unit (4) to read the transmission original. After performing predetermined signal processing such as encoding, the signal is transmitted to the telephone line (L) via the modem circuit (11) and the line switching circuit (12). During the period from the first operation of the one-touch key to the end of transmission, the operator checks the transmission destination displayed on the display (10), and if there is no error, presses the recording instruction key of the keyboard (9). Operate. The control circuit (3), which has detected that the recording instruction key has been operated at any time, sets a storage instruction flag in the control circuit (3).

Therefore, the control circuit (3) that has detected the end of transmission in step (S208) proceeds to step (S209) to determine whether or not the recording instruction flag is set, and if so, proceeds to step (S210). A recording instruction signal is transmitted, and then the process proceeds to step (S211) where the line switching circuit (1
2) is controlled to disconnect the line and return to the standby state. However, if the flag is not set, the process proceeds from step (S209) to step (S211). Therefore, if the recording instruction key is not operated, as in the case where an erroneous transmission is noticed during transmission, the recording instruction flag is not set, and the process proceeds from step (S209) to step (S211).

On the other hand, the control circuit (3 ') of the receiving-side facsimile apparatus (2) which has detected the incoming call in step (S301) by dial transmission from the transmitting-side facsimile apparatus (1) proceeds to step (S30).
Proceed to 2) to control the line switching circuit (12 ') to connect the telephone line (L) to the modem circuit (11') to connect the line. Then, the process proceeds to step (S303) to generate a response signal and transmit it to the transmitting facsimile machine (1). After proceeding to step (S304) to exchange control signals, in step (S305) image data from the transmitting facsimile machine (1) is received, and the data is written and stored in the receiving memory (7 '). If it is detected in step (S306) that the reception of all data has been completed, the process proceeds to step (S307) to detect whether or not a recording instruction signal has been transmitted, and if a signal has been detected, recording has been performed in step (S308). Set the flag,
Proceeding to step (S309), the line switching circuit (12 ') is controlled to disconnect the telephone line (L). However, if no signal is detected, the process proceeds from step (S307) to step (S309) to disconnect the line. After the line is disconnected, the control circuit (3 ') proceeds to step (S310) to determine whether or not the recording flag is set. If the recording flag is set, the control circuit (3') returns from the reception memory (7 ') in step (S311). After reading the data and performing signal processing such as decoding, the data is supplied to the recording unit (5 ') to perform reception recording. When all data has been recorded,
It returns to the standby state from step (S312). However, if the setting of the recording flag cannot be detected in step (S310), the process proceeds to step (S313) to clear the data in the reception memory (7 ') and return to the standby state. Thus, in the case of an erroneous transmission, the data in the reception memory (7 ') is not recorded in the recording section (5'), so that the received data is not read by a third party.

4 and 5 show another embodiment, in which a keyboard (9) is provided with a recording instruction key and an erasure instruction key.
If the recording instruction key is operated in the case of correct transmission, reception recording is performed on the receiving side. If the recording instruction key is not operated, the received data is stored in the receiving memory (7 ') and becomes confidential communication. In this case, when the delete instruction key is operated, the data on the receiving memory (7 ') is deleted on the receiving side.

That is, on the transmitting side, after detecting the end of transmission in step (S402), it is determined in step (S403) whether or not the recording instruction flag is set. If it is set, the recording instruction is determined in step (S404). A signal is transmitted, and then the line is disconnected in step (S405) to return to the standby state. However, if the flag set is not detected in step (S403), the process proceeds to step (S406) to determine whether or not the erase flag is set. If the flag is set, the erase instruction signal is transmitted in step (S407). Proceed to step (S405), and if not set, step (S4
06) to step (S405). Therefore, in the case of performing reception recording by normal transmission, the steps (S403) and (S40) are performed.
4) Proceed to (S405), and if confidential transmission is to be performed with normal transmission, proceed to steps (S403) (S406) (S405), and if there is an error, steps (S403) (S406) (S4)
Go to 07).

On the other hand, if the receiving end is detected in step (S502), the reception of the recording instruction signal is detected in step (S503). If the signal is detected, the process proceeds to step (S504), and the recording flag is set. ) To disconnect the line. However, if the recording instruction signal cannot be detected in step (S503), the process proceeds to step (S505) to detect the erasure instruction signal. Then, when the erase instruction signal is detected,
Proceeding to step (S506), the erasure flag is set, and then proceeding to step (S507). If no erasure instruction signal is detected, the process proceeds from step (S505) to step (S507). Next, after disconnecting the line in step (S507), the control circuit (3 ') proceeds to step (S508) to determine whether or not the recording flag is set, and if it is set, in step (S509). The data stored in the reception memory (7 ') is read and reception recording is performed. However, if the flag is not set in the determination in step (S508), the flow proceeds to step (S511) to determine whether or not the erase flag is set. If the flag is set, the flow proceeds to step (S512) to receive the data. The data in the memory (7 ') is cleared and the state returns to the standby state. But step (S51
If the flag setting cannot be detected in the determination of 1), the process proceeds to step (S513), a display indicating that confidential reception is present is performed on the display (10 '), and the process returns to the standby state. Thus, when there is a recording output instruction from the transmission side, in step (S509), the reception data stored in the reception memory (7 ') is read and reception recording is performed, and the recording output instruction is issued. If not, the received data is held in the receiving memory (7 '). Therefore, when a predetermined key operation is performed on the keyboard (9'), the data in the receiving memory (7 ') is read and recorded. Therefore, the received data is not read by an unspecified person. If the transmitting side notices an erroneous transmission during the transmission and gives an instruction for erasure, step (S512)
In this case, the data in the reception memory (7 ') is erased, so that the reception data is not read by a third party even in the case of an erroneous transmission.

In the above-described embodiment, the transmission original set in the reading unit (4) is transmitted while being read. However, it is configured that the read original data is temporarily stored in the data memory (6) and then transmitted. Is also possible.

(G) Effects of the Invention As described above, the facsimile system of the present invention is configured such that image data transmitted from the transmission side is stored in the memory on the reception side, and reception recording is performed when there is a recording instruction from the transmission side. Therefore, in the case of an erroneous transmission, the reception side does not record the reception, and the transmission contents are not read by a third party, which is a very practical effect.
