Abstract

PURPOSE:To connect a FAX to a slave machine after transmission and reception at the slave machine, and simultaneously, to perform the transmission directly from the FAX by connecting facsimile equipment to the slave machine, and simultaneously, storing a network control circuit in the same as well. CONSTITUTION:When it is decided that line wire incoming arrives and the facsimile equipment 2 is set previously at an automatic incoming mode, an F-relay 18 is controlled, and simultaneously, an LED 19 is lighted. As the result, since contacts 18a, 18b are switched to positions opposite to the positions shown in a figure, the equipment 2 is connected to a special line wire 4 through a current detection circuit 22, and a current is detected, and detection result is supplied to a CPU 15. Thus, in the CPU 15, a status is turned into a FAX receiving mode, and simultaneously, the LED 19 is flickered to enable the slave machine 1 to discriminate that a FAX image is being received. When the reception of the PAX image is finished, it is decided that the current is not detected, and system is restored to a state before the line wire incoming.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button telephone device to which a facsimile machine (sometimes abbreviated as FAX) is connected.

[Prior Art] A conventional method for connecting a two-wire terminal device such as a facsimile machine to the extension side of a key telephone device is disclosed in Japanese Patent Application Laid-open No. 63-23.
As disclosed in Japanese Patent No. 2671, it has been proposed that an additional control unit is connected between the main device and the slave device, and a standard facsimile device is connected to this control unit.

When using a facsimile device with this device, the line between the key telephone device and the main device is operated by a control section provided on the facsimile device side, and the line is switched to the facsimile device.

[Problems to be Solved by the Invention] However, although these conventional devices can be connected to a standard facsimile machine, when the handset is making or receiving a call, the call line is connected to the facsimile machine by operating the handset. There was an issue that it was not possible to transfer the data.

[Means for Solving the Problems] In order to solve such problems, the present invention provides a network control system (not shown) provided in the slave unit 1 by connecting the facsimile machine 2 to the slave unit 1, as shown in FIG. Depending on the circuit, slave unit 1
The facsimile machine 2 is directly connected to a specified outside line 4 by operating the handset 1 during an outgoing or incoming call.

[Function] An incoming call from a specific outside line 4 is answered by a handset 1 connected to the main device 5, and then transferred to the facsimile machine 2, and when automatic incoming calls are set, the facsimile machine 2 answers directly. After the call is made by the handset, it is connected to facsimile device 2, or it is connected to facsimile device 2
This is done by a standard wire telephone 3.

18a and 18b are contacts of the F relay 18, and 23 is a capacitor.

FIG. '3 is a flowchart showing the operation of the apparatus constructed as described above. In step 100, when there is an incoming external call, 't' JI is determined, and if the facsimile machine 2 is set to be in the automatic incoming fig mode, the Stellar 7
"101 is determined to be r Y E', S J, and the F relay 18 is controlled as shown in Step 1102, and the LED I 9 is controlled to light up as shown in Step 103. As a result, the contacts 18a and 18b is switched to a position opposite to that shown in the figure, and the facsimile machine 2 is connected to the specific outside line 4 via the current detection circuit 22. Current detection is performed in step 104, and the detection result is supplied to the CPU 15. By this, cp
ul 5 changes the status to F as shown in step 105.
While setting the AX reception mode, the LED 19 is made to blink as shown in step 106, so that the handset 1 can identify that it is receiving a fax. When the FAX reception is completed, it is determined "NO" in step 104, that is, current detection is no longer performed, and the state is restored to the state before the reception of the outside line.

If it is determined in step 1O1 that the call is not an automatic incoming call, and there is a response from handset 1 as shown in step 107, then as shown in step 108, whether the FAX transfer button (not shown) provided on the keypad 16 of handset 1 has been operated or not. It will be determined whether If it is determined that it is rYESJ, step 109 begins with 1. I! : I) IQ is controlled to light up, and as shown in step 110, L611z
The process of sending the calling signal to the facsimile machine 2 and the process of operating the relay 18 as shown in the Stella 71
detects the current from the station line 4 as shown in step 112, so step l! Change the status to 1 as shown in 3.
