Description

The present invention relates to a facsimile apparatus. (B) Conventional technology In general, in a facsimile machine, communication is performed based on a control procedure established by CCITT. When a final document is transmitted, as shown in FIG.
When the OP signal is transmitted and the MCF signal from the receiving side is detected, D
The CN signal has been transmitted, the line has been disconnected, and the process has been completed. (See, for example, JP-A-62-59456). Therefore, when transmitting both sides of a document, conventionally, the front side is first transmitted, then the call is made again and the back side is transmitted, or one side of the document is copied in advance and transmitted. There was a way to be done. However, in the former method, it is necessary to make a call again, transmission operation is required a plurality of times, and it takes time until the transmission is completed, and in the latter method, there is a problem that it is necessary to make a copy in advance and an extra cost is required. (C) Problems to be solved by the invention The present invention has been made to solve the above problems.
An object of the present invention is to provide a facsimile apparatus capable of transmitting both sides of a document by a simple operation. (D) Means for Solving the Problems The present invention provides means for instructing double-sided transmission of a document, and when the two-sided transmission is instructed by the means, discharges the document at the end of one-sided transmission of the document and outputs the document on the receiving side. And a control means for transmitting a signal for instructing double-sided transmission to maintain the line in a connected state. (E) Function Since the present invention is configured as described above, when transmitting both sides of a document, if the two-sided transmission is instructed by the instruction means, the line will be in a connected state even if the transmission of one side of the document is completed. Since the document is maintained, the discharged document can be set again to transmit both sides of the document. (F) Example Hereinafter, an example of the present invention will be described with reference to the drawings. (1) is a control circuit for controlling the entire facsimile apparatus, which is constituted by a microprocessor, and controls each section according to a program in a program memory (2) in which a processing program is stored. The control circuit (1) also performs signal processing of the read transmission original data and processing of the received signal. (3) a reading unit that optically reads a transmission original, converts the read black and white data into an electric signal, and supplies the electric signal to the control circuit (1);
It is composed of a lens mechanism, a lighting mechanism, an image sensor and the like. A recording unit (4) drives a recording head such as a thermal head under the control of the control circuit (1) based on the received signal to perform printing, and is composed of a recording paper and a recording paper transport mechanism and a recording head. A data memory (5) stores original data read by the reading unit (3), data subjected to signal processing, and the like. Data writing and reading are controlled by the control circuit (1). (6) is a keyboard composed of a transmission key, a reception key, a mode key, a numeric keypad, a double-sided transmission key, and the like. The control circuit (1) which has received a key signal receives a program memory (2) according to the key signal.
Control according to the program. (7) is a display for displaying data and the like input from the keyboard (6). Reference numeral (8) denotes a line switching circuit for switching and connecting the telephone (9) and the control circuit (1) of the facsimile apparatus to the telephone line (L), which is constituted by a relay circuit and controlled by the control circuit (1). When the two-sided transmission key is operated on the keyboard (6), the control circuit (1) that detects the key signal
Is set to store a flag indicating that the mode is the duplex transmission mode. Next, the operation of the present invention having the above configuration will be described with reference to the flowchart of FIG. First, the operation of transmitting a single-sided original will be described. After setting the transmission original in the reading unit (3) for transmission,
The telephone (9) dials the telephone number of the receiving facsimile machine, and a response tone (CE
When the transmission key of the keyboard (6) is operated after confirming the (D signal) with the receiver, the control circuit (1) that detects the transmission key signal in step (S3) uses the facsimile criterion in step (S4). After a predetermined control signal is exchanged, the transmission mode is set. The control circuit (1) that has completed the predetermined communication processing in this way controls the reading unit (3), encodes the read document data, and performs a training operation in step (S5). In step (S6), the original data is sent to the telephone line (L) for transmission. When the transmission of the original data is completed, an RTC signal is transmitted in step (S8), and it is determined in step (S9) whether or not the duplex transmission flag is set. Since is not set, the process proceeds to step (S10) to transmit an EOP signal. When the EOP signal is transmitted, the MCF signal sent from the receiving side is detected in step (S11), and when the MCF signal is detected, the process proceeds to step (S12), and after the DCN signal is transmitted, the telephone line is disconnected in step (S13). Is performed, and finally, the document is discharged in step (S14), and the transmission is completed. Next, the case of transmitting both sides of a document will be described. In this case, prior to transmission, the two-sided transmission key of the keyboard (6) is operated to set the two-sided transmission flag. Then, the front side of the document is set on the reading section (3), and the document data is transmitted by the processes of steps (S1) to (S8) in the same manner as described above. When the transmission of the front side is completed, the control circuit (1) determines the double-sided transmission flag in step (S9). Since the double-sided transmission mode is now set and the flag is set, the process proceeds from step (S9) to step (S15). Transmits the EOM signal and returns itself to phase B. Subsequently, the document is discharged in step (S16). Next, at step (S17), the MCF signal from the receiving side is detected, and upon detection, the double-sided transmission flag is reset at step (S18). As a result, the receiving side stands by in a mode for transmitting and receiving a so-called phase B communication signal by receiving the ECM signal. Then, when the operator on the transmitting side sets the back side of the discharged original in the reading unit (3), the control circuit (1) which has detected the setting of the original in step (S19) proceeds to step (S4) and performs the same operation as described above. Through the processing in steps (S4) to (S8), the back side of the document is transmitted. When the transmission on the back side is completed, the control circuit (1) determines the flag in step (S9), but since the flag has already been reset in step (S18), the control circuit (1) proceeds to step (S10) and executes the same as described above. Step (S14) of sequentially performing processing up to step (S13)
To discharge the original and end the transmission. Step (S11)
(S17) If no detection is performed in (S19), after a predetermined time has elapsed, processing such as disconnecting the telephone line and terminating the operation is performed. Thus, both sides of one document can be transmitted at a time. In the above-described embodiment, both sides of one document are transmitted. However, when transmitting both sides of a plurality of documents, the two-sided transmission key of the keyboard (6) is pressed during transmission of the back side of the document. By operating and setting the double-sided transmission flag, it is possible to transmit both sides of a plurality of documents. Further, in the embodiment, the EOM signal is used as the signal for instructing the transmission on the back side, but the MPS signal may be used. However, in this case, the EOM signal is preferable because the control circuit (1) performs a process of disconnecting the line according to the standard of the facsimile unless the original is set in the reading unit (3) within 10 seconds from the transmission of the MPS signal. . That is, when the EOM signal is used, the document may be set on the reading section (3) within 35 seconds ± 5 seconds according to the CCITT standard. It is also possible to use specific signals which are not in the facsimile standard. (G) Advantages of the Invention As described above, the facsimile apparatus of the present invention maintains the line connection state even after the transmission of the front side of the original is completed, by simply operating the two-sided transmission key of the original, and ejects the original. By setting the original again, the transmission of the back side can be performed continuously and the transmission of both sides of the original can be performed.
The function of the facsimile apparatus is improved, and the practical effect is extremely large. Further, in the present invention, since the two-sided transmission instruction by the two-sided instruction means is canceled at the end of one-sided transmission of the original when the two-sided transmission is instructed, the two-sided transmission can be designated for each transmitted original.
