(57) [Summary] [Purpose] The purpose is to automatically set the necessary telephone line type when a facsimile is installed. [Configuration] After the installation of the facsimile is completed, the power is turned on and at the same time a call is started to a specific station, and it is judged whether or not the call is connected to determine the type of telephone line to which the facsimile is connected. A fax machine that has a program that identifies it and makes appropriate settings. [Effect] When a facsimile is installed, the necessary settings can be made accurately without bothering the user.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a facsimile machine.

[0002]

[Prior Art]

 FIG. 3 is an overall block diagram of a general facsimile apparatus. In the figure, 1 is a facsimile machine, 2 is a DLO / extreme detection circuit, 3 is a dial pulse / DTMF generation circuit, 4 is a CI detection circuit, 5 is a CML relay, 6 is a modem, 7 is a control CPU, and 8 is a control unit. ROM, 9 is a transmitter, 10 is a receiver, 11 is a telephone line, 12 is a telephone, and 13 is a telephone line selector switch.

Next, setting of the telephone line type of the facsimile apparatus 1 will be described. There are three types of telephone lines 11 to which the fax machine 1 is connected: a touch-tone telephone line, a dial line (dial speed 10pps), and a dial line (dial speed 20pps). When the facsimile device 1 is installed, the user must first identify the type of the telephone line and set the telephone line changeover switch 13 to the proper position. As a result, the dial pulse and DTMF generating circuit 3 cannot be set up correctly according to the type of the telephone line 11 to which the facsimile device 1 is connected until the facsimile device 1 can make an accurate call.

[0004]

[Problems to be solved by the device]

 Since the conventional facsimile machine is configured as described above, when it is installed, the user can identify the type of telephone line to which the facsimile is connected, and if the telephone line selector switch is not set properly, the facsimile machine will function normally. There was a problem that it did not work.

The present invention has been made to solve the above problems, and when the fax machine is installed, the type of the connected telephone line is identified and an appropriate setting is automatically performed. The purpose of the present invention is to obtain a facsimile device having a function capable of performing.

[0006]

[Means for Solving the Problems]

 The facsimile apparatus according to the present invention discriminates the type of telephone line by turning on the power after completion of installation and at the same time starting a call to a specific station and determining whether or not the call is connected. It has a series of programs that automatically make appropriate settings.

[0007]

[Action]

 The facsimile according to the present invention automatically sets appropriate settings by a series of programs that internally have the necessary telephone line type settings when installed.

[0008]

【Example】

 Example 1. An embodiment of this invention will be described below with reference to FIG. In the figure, 1 is a facsimile device, 2 is a DLO that detects a polarity reversal of the line that occurs when the line is closed, a polar reversal detection circuit, 3 is a dial pulse / DTMF generation circuit, 4 is a CI detection circuit, and 5 is A CML relay, 6 is a modem, 7 is a control CPU, 8 is a ROM, 9 is a transmitter, 10 is a receiver, 11 is a telephone line, and 12 is a telephone. FIG. 2 is a flow chart of a program for automatic telephone line identification programmed in the ROM 8 of FIG.

When the power is turned on after the installation of the facsimile apparatus 1 is completed, the telephone line automatic identification program programmed in the ROM 8 of FIG. 1 is activated. The flow chart of the program is shown in FIG. A description will be given below with reference to FIG. When the power of the facsimile machine 1 is turned on, first, the dial line / DTMF generating circuit 3 of FIG. 1 is set to the dial line (10 pps). Then, the call is started to a specific station, for example, 117 (time signal). Then, the DLO / resonance detection circuit of FIG. 1 detects whether or not the call is connected. If the call is not connected here, it is judged that the telephone line 11 in FIG. 1 is a push-phone line, the telephone line setting of the dial pulse / DTMF generation circuit 3 in FIG. Put device 1 in standby. On the other hand, if the call is connected here, the line is disconnected once, the telephone line setting of the dial pulse / DTMF generating circuit 3 in FIG. 1 is changed to the dial line (20 pps), and the call is started again at 117. . Then, again, the DLO / resonance detection circuit 3 of FIG. 1 detects whether or not the call is connected. If the call is not connected here, it is determined that the telephone line 11 in FIG. 1 is a dial line (10 pps), the telephone line setting is changed to dial line (10 pps), the program is terminated, and the facsimile machine 1 is in the standby state. To On the other hand, if the call is connected here, it is judged that the telephone line 11 in FIG. 1 is a dial line (20 pps) and the program is ended as it is, and the facsimile apparatus 1 is set to the standby state.

Example 2. In the above embodiment, the activation timing of the program for automatically identifying the telephone line type shown in FIG. 2 was described as when the power of the facsimile device 1 in FIG. 1 was turned on. However, the program is separately provided in the facsimile device 1 in FIG. By providing the start-up switch, the start-up timing may be set, and the same effect as that of the above-described embodiment can be obtained.

[0011]

[Effect of the device]

 As described above, according to the present invention, when a facsimile is installed, it is possible to automatically set the telephone line type, which conventionally had to be set by the user himself, so that the user is not bothered. It also has the effect that it can be set accurately.
