Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual polling control system for a facsimile, and more particularly to a manual polling control system capable of reducing the number of mode setting switches by providing means for determining a mode according to various conditions. is there.

[0002]

2. Description of the Related Art Conventionally, a facsimile apparatus having a polling function has been known, and many inventions relating to polling have been proposed. However, the technology proposed up to now includes, for example, Japanese Patent Laid-Open No. 60-28372, but the polling side and the poled side (polling side).
It is an invention in the case where is clear, and there is nothing related to the case where the polling side and the polled side are not decided, that is, the case where the polling operation is manually performed.

Conventionally, when manually performing a polling operation, a button switch for selecting a plurality of operation modes is prepared, and an operator recognizes whether the operation is a polling operation or a poled operation, and selects a corresponding switch. Had to operate.

FIG. 6A is a time chart showing the operation of the manual polling control system in the conventional facsimile apparatus. In this example, after the facsimile terminals A and B have made a voice call with the attached telephones, the document is transmitted from the terminal B to the terminal A by the polling operation.

An operator sets a transmission original in the terminal B in advance, and then a polling switch is set in the terminal A and a reception mode is set in the terminal B, and the original is transmitted by being polled by the terminal A. The switch is pressed. In the terminal B, since the receiving switch is pushed down, the receiving mode is set, and the CED signal sent in the normal automatic receiving mode is omitted, and the DIS
The signal is sent out.

On the other hand, since the terminal A has been set to the polling mode, it waits for the DIS signal to be received, and when the DIS signal is received, it indicates that polling is used instead of the DCS signal in the normal transmission mode. Send a DTC signal. By receiving the DTC signal at the terminal B, it is possible to know that the other party is in the polling mode and to send a facsimile message from the terminal B side.
First, the DCS signal is transmitted.

After that, the transmission procedure is the same as the normal facsimile communication when the terminal B is the calling side and the terminal A is the called side, and the facsimile message is transmitted from the terminal B to the terminal A. For these procedures, see CC
ITT Recommendation T. It is standardized in 30 grade.

[0008]

In the conventional facsimile apparatus as described above, in order to perform the manual polling operation, a polling and receiving switch is prepared, and whether the operator performs the polling operation or the polled operation. Therefore, there is a problem that the operation is troublesome and the manufacturing cost is high because it is necessary to recognize whether or not it is.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to obtain a manual polling control system capable of easily setting a mode with a smaller number of switches in a facsimile machine.

[0010]

The modem 10 has a low speed mode (for example, V21) for commands and a high speed mode (V21) for image data.
27 ter, V29, V33, V17, etc.) and modulates the command and image data from the communication control device 9 according to the modulation method defined by each standard, or demodulates the received signal. Network control device 11
Under the control of the communication control unit 9, for example, automatic call originating / receiving operations such as calling, dialing and disconnecting to a public network such as a telephone line are executed. The system bus 12 connects each device in the facsimile device.

FIG. 2 is a functional block diagram showing the relationship between the functional elements in the embodiment. The outline of the operation will be described based on this figure. The operator instruction detecting means 20 is means for detecting the instruction of the manual polling process by the operator by checking the state of a predetermined switch. The transmission document presence / absence detecting unit 21 checks whether a document is set in the reading device 4 or whether document data to be transmitted is stored in the image storage device 7,
It is a means for detecting the presence or absence of a transmitted document.

The signal detecting means 22 is means for checking whether a DIS signal is received from the line or whether a CNG signal is detected. When the DIS signal is sent from the other party, the other party is in the reception mode and CNG
When the signal is sent, it is known that the other party is in the transmission mode. The timer means 23 is started based on the output from the operator instruction detecting means 20 and measures the time, and is provided with means for controlling the measuring time according to the output from the transmission document presence / absence detecting means 21. Good.

The mode selection means 24 is an operator instruction detection means 20, a transmission document presence / absence detection means 21, a signal detection means 2.
2. Based on the output of the timer means 23, either the polling mode or the receiving mode is selected. According to the mode type output from the mode selection unit 24, the command transmission unit 25 receives the DIS signal in the reception mode and the DIS signal from the other party in the polling mode, and therefore indicates the polling. Send the DTC signal. These means are mainly realized by a program stored in the ROM 8 or a program in the communication control device 9.

Next, details of the operation of the embodiment will be described. FIG. 3 is a flowchart showing a mode determination process when a predetermined switch is pressed in the embodiment. In the facsimile apparatus, when a predetermined switch is pressed during a voice call, first, in step S10, a timer of, for example, 4 seconds is started.

At step S11, the DI from the line
It is checked whether the S signal is received, and if so, the polling mode is selected. This is D
The fact that the IS signal has been transmitted means that the other party is in the reception mode, and it is necessary to perform polling from here.

When the DIS signal is not received in step S11, the process proceeds to step S12 and CN
It is checked whether or not the G signal is received, and when the CNG signal is received, the other party is in the transmission mode.
Set the device on this side to receive mode. When the CNG signal is not received in step S12, the process proceeds to step S13.

In step S13, it is checked whether or not the original document to be transmitted is set or the original document data to be transmitted is stored in the image storage device 7. If there is information of the original document to be transmitted, Move to receive mode. However, if not, the process proceeds to step S14.

In step S14, it is checked whether or not the operator has instructed to set the reception mode. If there is an instruction to set the reception mode, the mode is shifted to the reception mode, and there is no setting instruction to the reception mode. If so, the process proceeds to step S15. The instruction to set the reception mode by the operator is given, for example, by pressing a predetermined switch twice or more within a predetermined period.
Separately from this, an instruction to set the polling mode by the operator may be identified and the polling mode may be entered.

In step S15, step S1
It is checked whether or not the timer started at 0 has timed out. If the timer has timed up, the mode is shifted to the reception mode. If not, step S11.
And the condition determination process is repeated. Since the processing in the polling mode and the reception mode is well known as described above with reference to FIG. 6A, detailed description thereof will be omitted. Further, the condition determination process from step S12 to step S14 is not essential, and any or all of the determination processes may be omitted.

FIG. 4 is a flow chart showing a modification of the mode determining process in FIG. 3 when a predetermined switch is pressed. In the facsimile apparatus, when a predetermined switch is pressed during a voice call, first, in step S20, it is determined whether the transmission original is set or the original data to be transmitted is stored in the image storage device 7. Is checked, and if there is information on the original to be transmitted, the mode shifts to the reception mode, and if there is no information, the procedure shifts to step S21.

Subsequent steps S21 to S
The processing up to 25 is the same as the processing from step S10 to step S15 in FIG. However, in the modification of FIG. 4, the process of step S13 of FIG. 3 is omitted. (It need not be omitted.) FIG. 5 is a modification of the embodiment of FIG. In FIG. 5, when a predetermined switch is pressed during a voice call in the facsimile apparatus, first, in step S30, the transmission original is set or the original data to be transmitted is stored in the image storage device 7. If there is information on the original to be transmitted, the process proceeds to step S32. If not, the process proceeds to step S31.

In step S31, step S3
The timer is started by setting a time longer than 2, for example, 8 seconds. On the other hand, in step S32, step S3
A timer shorter than 1 is set, for example, 4 seconds, and the timer is started. Although not shown thereafter, the process proceeds to step S22 in FIG. 4 and the same processing as in FIG. 4 is performed.

FIG. 6B is a time chart showing the operation of the manual polling control system of the above-described embodiment shown in FIGS. In this example, as in the case of FIG. 6A, a case where a facsimile communication is performed from the terminal B to the terminal A by a polling operation after the facsimile terminals A and B make a voice call using the attached telephones is shown.

An operator sets a transmission document in advance in the terminal B, and then in the terminals A and B, a predetermined switch is pressed. In the terminal B, since the transmission original is set, the transmission mode is set (or the timer is timed up) to set the reception mode, the CED signal transmitted in the normal automatic reception mode is omitted, and the DIS signal is transmitted.

On the other hand, the terminal A monitors the reception of the DIS signal until the timer times out. When the DIS signal is received, the terminal A is set to the polling mode, instead of the DCS signal in the normal transmission mode. , Send a DTC signal to indicate polling. By receiving the DTC signal, the terminal B knows that the other party is in the polling mode, and the terminal B first sends a DCS signal in order to send a facsimile message.

After that, the transmission procedure is the same as the normal facsimile communication when the terminal B is the calling side and the terminal A is the called side, and the facsimile message is transmitted from the terminal B to the terminal A. As described above, in the case of the embodiment of the present invention, the same switch is pressed on both the transmitting side and the receiving side,
Each mode is set automatically.
