Abstract

PURPOSE:To simplify the setting of ID number and its confirmation, by starting transmission after discrimination of the ID number included in a dial tone from an opposing facsimile with a means discriminating the dial tone. CONSTITUTION:At the caller side A, a user at the caller side makes a call with dialing. The called party receives a call signal with an automatic response function and transmits a CED signal, an NSF signal and a DIS signal. At the caller side B, the telephone number of itself is again dialed after the confirmation of the automatic reception mode. The ID number inputted from an input circuit 20 for the ID number setting is stored in a memory circuit 22. The dial tone transmitted from the caller side is received at a reception circuit 26, the received ID number is stored in a buffer memory 28 and compared with the number in the memory 22 at a comparison circuit 24.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile machine, and particularly to a facsimile machine in which a calling facsimile machine starts automatic transmission of a document after a calling facsimile machine sets up a call (hereinafter referred to as polling transmission).

Conventionally, polling transmission in facsimile machines is often performed in accordance with CCITT Recommendation T/Recommendation order.

FIG. 1 shows the procedure. In the figure, it is assumed that the facsimile machine on the called side is set to automatic response, and the facsimile machine on the calling side is set to manual. The called side first transmits a CED (called station identification) signal, an NSF (non-standard equipment) signal, and a DIS signal (a digital identification signal indicating that the called station equipment has a CCITT function) at 3-second intervals. In response, the calling party presses the receive button at point A, then transmits the NSF signal and DIS signal at 55-second intervals and repeats this process.Then, at point B in Figure 1, the called party receives the NSF signal. - When the calling party receives the DIS signal, it responds to the NSC (non-standard equipment command) signal and the DTC.
Send a signal (digital transmission command). On the other hand, the called party
When a DTC signal is received at the time of , the identification number (hereinafter referred to as ID number) included in the NSC signal is compared with its own ID number to confirm the other party's facsimile machine. If the person is determined to be a person to whom you can send the manuscript after confirmation, then
After sending out the SS signal (non-standard device setting color number) and DO3 signal (digital command signal), the sending operation is executed. - If the ID numbers on the other party's side and the ID numbers on the own side do not match, polling transmission will not be executed.

FIG. 2 shows an ID determination circuit of a facsimile machine having such a conventional polling function. In the figure, 10 is a switch circuit for setting an ID number, and the ID number input from this switch circuit is is memory circuit 1
Also, the ID number in the NSC signal sent from the calling side is detected by the detection circuit 16. This detection circuit is composed of a V21 modem recommended by CCITr, and The detected ID number is stored in the buffer memory 18. The ID numbers stored in the memory 12 and the buffer memory 18 are compared by the comparison circuit 14, and the comparison result is outputted to the output 14-a.

The ID number verification as described above is performed to prevent important confidential documents from being sent to an unspecified person. The ID number can be set individually by the user using a switch or numeric keypad, and there are devices that always have only one ID number and devices that store a plurality of ID numbers.

In the former case, users who perform polling communication will have the same ID number, but this requires resetting the ID every time it is necessary to perform polling communication with a user in another group. is troublesome. Listen again
As the number of groups with ID increases, it becomes necessary to change the ID and sort out some tin materials within the group.

In the latter case, the telephone number to which the facsimile IJ is connected can be used as the ID number. In this case, as mentioned above, it is necessary to change the stored ID depending on the document within the group, and if the phone number to which the facsimile is connected changes, it is necessary to reset the ID number. be.

As explained above, ID number management for conventional polling communication is an additional operation to the familiar sequence of making a call and pressing a communication button.
There are many inconvenient parts.

The present invention has been made in view of the above points, and an object of the present invention is to provide a facsimile device with good operability that can handle ID numbers in polling communication in a manner similar to the normal telephone dialing operation (3). There is.

According to the present invention (-), in order to achieve this object, a means for identifying the dial tone of the telephone set is provided, and the dial tone (1
A configuration was adopted in which automatic transmission of the manuscript is started after identifying the ID number included.

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 4 illustrates the principle of the present invention, and the difference in FIG. 4 from FIG. 1 is that the ID number is transmitted by a dial tone. At A, the calling user dials and makes a call. The called party is activated by the automatic answering function upon receiving the calling signal, and receives the CED signal, NS
Sends F signal and DIS signal. Next, the calling party confirms at B that the other party's machine is in automatic reception mode, and then dials his or her telephone number again. in this case,
This dial tone sends out an ID number.

(4) This ID number transmission is configured as shown in Fig. 5, where the "#" tone is a signal indicating the start of sending a dial tone, while the "r*") tone is a dial tone. A numerical ID number is inserted between these two tones.

In this way, at point C, when dialing a series of telephone numbers is completed, the receive button is pressed. Thereafter, polling communication is performed using the same procedure as in FIG. In this case, the called side confirms the ID number sent by the calling side using a dial tone at point D, and then enters polling communication.

FIG. 4 shows an ID determination circuit used in the present invention. In the figure, 20 is an input circuit for setting an ID number consisting of a numeric keypad type input circuit. The ID number is stored in memory circuit 22. On the other hand, the dial tone sent from the valve calling side is, for example, a commercially available IC, MK5102 (MO5TE).
The signal is received by a receiving circuit 26 made up of a company such as Company K). This received ID number is stored in the buffer memory 28 and then compared with the ID number in the memory 22 by the comparison circuit 24 (secondary) and the comparison result is outputted to the output 24-a. When setting a document to be sent by polling, the ID number of the other party, for example, a telephone number, is input using the input circuit 20.

In the above-described embodiment, the telephone number can be used as the ID number, but the ID number can also be a mutually agreed-upon dark part, and the input circuit 20 can be replaced with a numeric keypad-type input circuit by using an input circuit similar to the button layout of a Butschhorn telephone. It can also be a circuit.

Furthermore, in the present invention, the key point is to compare the ID numbers by transmitting and receiving a dial tone again after the call is set up.
There is no problem even if the procedure from C onwards after sending the dial tone in the figure is changed and a direct N5C-DTC signal is sent from the calling side.

As described above, according to the present invention, means for detecting a dial tone is provided, and polling communication is performed by detecting the ID signal included in this dial tone.
The number setting and confirmation operations can be replaced with the laborious operations of (7) dialing a telephone, and an inexpensive and easy-to-use facsimile device can be provided. Particularly if a Bushhorn telephone is used, the operations described in (-) can be completed in a short time. Further, with a regular subscriber telephone line, there is an advantage that the dial tone can be reliably delivered to the other party as a voice signal even after the call is set up.
