BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile, and detects and reports a facsimile when the facsimile is in use, and detects and reports the facsimile when a call is received. About.

[0002]

2. Description of the Related Art A device for detecting and informing that a facsimile is in use has been known.
There are known a method of detecting an incoming signal connected to a telephone line and a method of monitoring a loop of the telephone line. However, the conventional method detects the use of a telephone line and a facsimile because the current detection sensor unit is of the connection type as described above,
The device to be notified was used after connecting by telephone line construction.

[0003]

[Problems to be solved by the invention] As a result, the telephone line must be connected to a device for detecting and notifying the use of a facsimile and a telephone line. There was a problem that the construction had to be costly, and it was not possible to detect an incoming call from the other party's facsimile and to display the information. In this case, in view of the above-mentioned problems, the present invention does not need to connect a device for detecting and notifying the use of a facsimile to a telephone line, and can detect and notify an incoming call from the other party's facsimile. In order to detect the operating current of the facsimile, there is no need to provide any contactless facsimile in-use display device which does not require any modification to the facsimile's AC100V power cord.

[0004]

The above object can be attained by adopting the following novel characteristic constitution means of the present invention. That is, the feature of the present invention is that a non-contact type current detecting unit which detects an operating current at the time of sending and receiving of a power cord of a facsimile and generates a detection signal, and a detection method which receives a detection signal from the non-contact type current detecting unit and performs the detection. A detection signal processing unit that issues a notification command signal at the same time as holding the signal and that is connected to a reset unit, and displays the connected notification lamp when receiving the notification command signal from the detection signal processing unit, and displays a notification lamp for a predetermined time from the notification speaker. This is a non-contact type facsimile in-use display device including a notification control unit that emits sound.

[0005]

Since the present invention employs the above-described means, the contactless current detection unit detects the operating current of the AC100V power cord β of the facsimile α to notify that the facsimile α is being used, and informs the other party of the facsimile α. Incoming calls are also detected and reported. Therefore, the necessity of telephone line work is not required in use, and no change is required to the AC 100 V power cord β of the facsimile α.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is an explanatory diagram of a mounting form of a non-contact type current detecting unit sensor and a power cord of a facsimile of the present embodiment, and FIG. 2 is a system configuration diagram of the present embodiment. In the figure, 1 is a contactless facsimile in-use display device, α is a facsimile, and 2 is an AC of a facsimile α.
Non-contact type current detection unit attached to 100V power cord β without contact, 3 is detection signal processing unit, 3a is drive circuit, 4 is reset unit, 5 is notification control unit, 5a is visible notification drive circuit, 5b
Denotes an audible notification drive circuit, 5c a timing setting circuit, 6 a notification lamp, and 7 a notification speaker.

The specification of the present embodiment is such a specific embodiment, and its operation will be described. Although almost no current flows through the facsimile α that is normally waiting for reception, an operating current is generated at the time of outgoing / incoming calls, and this is sent to the sensor 8 of the contactless current detection unit 2 attached to the AC100V power cord β without contact. When the detection is performed, it is converted into an electric detection signal I and transmitted to the detection signal control unit 3, and the relay A of the drive circuit 3 a in the detection signal processing unit 3 is driven and held at the ground 9 of the reset unit 4. . Next, when the notification command signal I2 output from the detection signal processing unit 3 is input to the notification control unit 5, the notification control unit 5 drives the visible notification drive circuit 5a, and turns on or blinks the notification lamp 6. And the like, and drive the audible notification drive circuit 5b to perform audible notification by the melody of the notification speaker 7.

[0008] In this case, the auditory notification by the notification speaker 7 is automatically stopped after a lapse of the time T by an arbitrary timing setting circuit 5c of the notification control unit 5. Usually, this arbitrary set time T is several seconds. Also, notification lamp 6
Is held until the reset button 4a of the reset unit 4 is depressed. At this time, when the reset button 4a is depressed, the relay A in the detection signal processing unit 3 is restored, the entire non-contact type facsimile in-use display device 1 is restored, and the operation returns to the standby state of the operation of the original facsimile α. is there.

The reset button 4a of the reset unit 4
If the facsimile α is restarted due to an incoming call or the like before the key is pressed down, the notification lamp 6 is turned on and blinks without interrupting the notification, and the melody sound of the notification speaker 7 is again set to the arbitrary set time T. The alarm sounds during the alarm.

Now, another mode of attaching the non-contact type current detecting section and the power cord of the facsimile shown in FIG. 3 will be described. The current detecting section 2 'is directly connected to a 100V AC power supply via the power cord β1 and the facsimile is connected. The plug ε may be inserted into the outlet γ in which the power cord β of α is attached to the current detector 2 ′.

[0011]

[Effect of the Invention] Thus, according to the present invention, the operating current of the facsimile AC100V power cord is detected by the non-contact type current detection sensor, so that no change is required to the facsimile AC100V power cord, and the telephone Line construction is not required, and not only does it take time and effort to set up, but also the type of facsimile to be installed is not particularly limited, it is versatile, and it can detect and report incoming calls from the other party's facsimile. It has practicality and usefulness.
