DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile machine having an automatic switching function between manual reception and automatic reception.

BACKGROUND OF THE INVENTION At present, facsimile devices are sometimes installed on dedicated facsimile lines that are independent of telephone lines, but in many cases they are also installed on telephone lines.

FIG. 2 is a block diagram showing an example of a facsimile device used in this manner.

In the figure, 1 is a central office line, and this central office line 1 is connected to a telephone line outside the device. 2 is a relay that switches the telephone line between the telephone 3 and the facsimile machine body 6; 4 is a bell ringing signal detection circuit; this detection circuit 4 is connected to the office line 1 and the telephone 3; 06 is a line transformer; This line transformer 6 is connected to the relay 2 and the facsimile machine main body 6.

7 is a signal line that guides the detection signal from the bell ringing signal detection circuit 4 to the facsimile machine main body 6, and 8 is a bell signal detection circuit 4 that conducts manual reception and automatic reception of the facsimile machine main body 6.
This is a signal line that guides signals that control the entire operation of this detection circuit 4. 9 is a transmission/reception switch provided on the main body 6 of the facsimile machine.

When the facsimile machine having the above configuration is in the manual reception state, the fact that the main body 6 is in the manual reception state is outputted to the bell ringing signal detection circuit 4 via the signal line 8, and this detection circuit 4 receives a signal of 16 Hz. The device is set not to detect incoming bell ringing signals. In this case, 16
When the Hz bevel motion signal is received, the bell of the telephone 3 rings via the central office line 1. When the telephone 3 is hooked off, the telephone line is connected to the telephone 3. When the facsimile signal (tone signal) from the calling side is confirmed, the called side turns on the transmit/receive switch 9. When the transmit/receive switch 9 is turned on, a signal is sent from the axis device main body 6 to the line transformer 6.

The signal sent from the device main body 6 is sent to the line transformer 6'f.
, and is input to relay 2, which switches the telephone line to the facsimile machine side.

Following the above steps, facsimile communication was carried out.

Problems to be Solved by the Invention However, in such a configuration, priority is given to the telephone function during manual reception, so there is a problem that communication becomes impossible unless the telephone is hooked off in the manual reception state when the receiver is absent. friend.

The above problem arises for the following reasons. In other words, firstly, switching between the telephone and factor during manual reception and the telephone line of the SIJ device can only be done using the reception switch, and the telephone must be hooked off. If the calling party is in manual reception mode, the bell ringing signal detection circuit will not operate.

The present invention has been made in order to solve the above-mentioned problems, and the facsimile machine automatically switches from manual reception to automatic reception without becoming unable to communicate even if the telephone is not hooked off. Instead, it is an object of the present invention to provide a facsimile device capable of performing facsimile communication.

Means for Solving the Problems In order to achieve the above object, the present invention inputs a next bell ringing signal transmitted from a telephone line, compares this signal with a preset reference value, and calculates the result of this comparison. and measuring means for controlling switching means between manual reception and automatic reception based on the above information.

Examples of the measuring means include a timer that directly measures the detection time of the bell ringing signal, or a counter that measures the ringing time by counting the number of times the bell ringing signal is detected.

Operation After the bell ringing signal arrives, the bell ringing detection circuit detects the incoming call and activates the measuring means. When the measuring means exceeds a preset reference value, it outputs a pulse signal to the facsimile machine body, and the facsimile machine body receives this and sends it to the manual reception/automatic reception switching means (hereinafter referred to as a relay). By outputting a signal, the relay switches the telephone line from the telephone side to the facsimile machine side, allowing facsimile communication without hooking off the telephone.

Embodiment FIG. 1 is a schematic configuration diagram showing a facsimile machine according to an embodiment of the present invention.

In the figure, 21 is a central office line, and this central office line 21 is connected to a telephone line outside the device.O22 is a relay that is manual reception automatic reception switching means, and this relay 22 connects the telephone line to the telephone 23 side and the facsimile machine. Switch to the main body 26 side.

24 is a bell ringing signal detection circuit for detecting a 1e Hz bell ringing signal, 26 is a line transformer, and 3o is a counter serving as a bell ringing time measuring means for counting the arrival of the bell ringing signal a certain number of times. 27 is a signal line for sending a pulse signal outputted by the overflow of the counter 30 to the main body 26 of the facsimile machine, and 29 is a transmitting/receiving switch provided in the main body 26.

When the above device receives a 1e Hz bell ringing signal during manual reception, the bell ringing signal detection circuit 2
4, this incoming call is detected and the bell of the telephone 23 is rung. When the bell ringing signal detection circuit 24 detects the arrival of a bell ringing signal, a pulse signal is sent to the counter 3 every time it is detected.
The counter 3o counts the number of incoming bell ringing signals. The counter 30 has a reference count number set in advance, and if the telephone 23 continues to receive the bell ringing signal without being hooked off, the counter 30 continues counting and when it reaches the reference count number, the signal line 2
7, a pulse signal is output to the facsimile machine body 26.
is input. The facsimile machine body 26 outputs a pulse signal to the line transformer 26 in response to the input of this pulse signal, and the pulse signal transformed by the line transformer 25 operates the relay 22 to connect the telephone line from the telephone 23 side to the facsimile machine body 26 side. Switch to

In this embodiment, the counter 30 is used as the measuring means, but a timer may also be used as the measuring means. If the measuring means is a timer, the timer operates when the bell ringing signal detection circuit 24 detects the arrival of the first bell ringing signal, and if the telephone 23 is not hooked off by a preset reference time, it is assumed that the time has elapsed. A pulse signal is output from the timer to the signal line 27. The following operations are the same as when using a counter.

In addition, a facsimile-equipped telephone with the above-mentioned device configuration and function usually operates in manual reception mode when the called party is present, but when the recipient is absent, it switches to automatic reception mode and can be used as an answering machine. Even if the caller is in manual reception mode when the caller is absent, the telephone M-Facsimile side is switched, and even if it is impossible to make a call, the calling party can send a message to the called party via facsimile communication. .

Effects of the Invention According to the present invention, there is provided a facsimile machine having means for switching between manual reception and automatic reception, which includes a measuring means associated with a bell ringing signal detection circuit, and this measuring means detects the bell ringing signal according to a preset standard. Since manual reception and automatic reception switching means are controlled based on the value, even if the called side is not hooked off during manual reception, the telephone line can be automatically switched from the telephone side to the facsimile device side and facsimile communication can be performed.
