DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an example of the hardware configuration of a facsimile device F including an attached telephone according to the present invention. The facsimile device F is a device in which a facsimile communication control unit 1 for executing facsimile communication and an attached telephone D are connected to a communication line L.
The facsimile communication control unit 1 and the attached telephone D are C
It is configured to be controlled by the signal processing unit 2 including a PU or the like.

Of the above, the facsimile communication control unit 1
Is a modem 1a for transmitting / receiving image data, a relay switch 1b for connecting and disconnecting the line of the modem 1a to / from the communication line L, and a ringing signal for detecting a ringing signal (16 Hz bell signal) transmitted from a line exchange. It is provided with a detection circuit 1c, a dial circuit 1d for transmitting dial pulses for dialing, and the like.

The signal processing unit 2 includes a storage unit 3 as a system memory composed of a ROM and a RAM, an operation unit 4 including a mode setting key 4a and other general operation keys, and an original image for scanning. An image reading unit 5, a print output unit 6 for printing out predetermined image data on recording paper, a display unit 7 including a liquid crystal display, and the like are connected. Of these, the mode setting key 4a of the operation unit 4 can arbitrarily select and set the standby mode of the facsimile apparatus F. As a specific example of the standby mode, for example, a ringing signal from a circuit switch is received a predetermined number of times. When the call is sent, the facsimile communication control unit 1 makes a non-ringing incoming call, and then the calling side C
If a predetermined protocol signal such as an NG signal is transmitted, the facsimile communication procedure is started. If not, there is a telephone / facsimile mode in which the attached telephone D prompts a response. This mode corresponds to the standby mode in which a silent incoming call is requested according to the present invention. In addition to this standby mode, a telephone mode for prioritizing a response from the auxiliary telephone D, a facsimile mode for prioritizing facsimile reception, or the like can be set. In these modes, a silent ringing request is requested. Not done.

The attached telephone D is provided with a call circuit 10 for enabling a call with the handset H, a ringer circuit 11 for ringing a bell when a ringing signal transmitted from a circuit switch is received, a speaker SP and the like. I did it,
The ringer circuit 11 is always connected to the communication line L. Further, the call circuit 10 is connected to the communication line L via the hook switch HS. When the operator picks up the handset H, the hook switch HS is turned on, and the call circuit 10 is connected to the communication line L.

Further, a switching circuit 12 is provided between the ringer circuit 11 and the speaker SP.
When a predetermined control signal is input to the switching circuit 12 from the signal processing unit 2 via the photocoupler 13, the input of the sound signal from the ringer circuit 11 to the speaker SP side is blocked or dropped to the ground. Thus, the bell sound is not generated from the speaker SP. The ringer circuit 11 including the switching circuit 12 and the speaker SP correspond to the bell ringing means according to the present invention. The photocoupler 13 isolates the attached telephone D from the signal processing unit 2. This is because the auxiliary telephone D is operated by the current on the communication line L and needs to be isolated from the signal processing unit 2.

The signal processing unit 2 corresponds to the control means according to the present invention, and a standby mode in which a silent incoming call is requested such as the telephone / facsimile mode described above is set by operating the mode setting key 4a. In this case, a predetermined control signal is continuously output to the switching circuit 12 of the attached telephone D.

In the facsimile apparatus F having the above-mentioned structure, when the telephone / facsimile mode in which a silent incoming call is requested is set, a predetermined control signal is input from the signal processing unit 2 to the switching circuit 12 of the attached telephone D. Then, this state is maintained, and the generation of the bell sound from the speaker SP is blocked. Therefore, the attached telephone D is connected to the communication line L.
Even if the external communication terminal makes a call to the facsimile apparatus F and the call signal is transmitted from the circuit switch, the facsimile communication control unit 1 does not ring. It is possible to have the side make an automatic incoming call.

When another type of standby mode in which no ringing is required is set, the control signal is not input from the signal processing unit 2 to the switching circuit 12,
When a call is made to the facsimile machine F from the outside, the bell ringing can be appropriately performed by the attached telephone D, and no trouble occurs.

In the above-mentioned embodiment, the telephone / facsimile mode is given as an example of the standby mode in which a silent incoming call is requested. However, the present invention is not limited to this, and the standby mode other than this is not used. It does not matter if the ringing call is made. Whether or not to receive no ringing is a matter that the maker or the user can select as appropriate.

[0016]

As can be understood from the above description, according to the facsimile apparatus equipped with the attached telephone according to the present invention, the bell of the attached telephone can be operated with the attached telephone connected to the communication line. Since it is possible to switch between ringing incoming calls and non-ringing incoming calls, it is not necessary to use parts such as a relay switch for connecting and disconnecting the attached telephone with respect to the communication line, and its control can be facilitated. The effect is that the manufacturing cost of can be reduced.
Moreover, since it is sufficient that the attached telephone is always connected to the communication line, by making the telephone circuit of the attached telephone always connected to the communication line, it becomes possible to make effective use of the communication circuit.
