Abstract

PURPOSE:To make possible facsimile reception by accepting a remote signal only for a certain time from a ring signal stops and making a judgement if an attached telephone set is in the on-hook state. CONSTITUTION:When ring signal detection stops before the ring signal is inputted as many times as specified, a control means 17 detects whether or not the attached telephone set 5 is in the off-hook state by a detecting means 9. When the telephone set is not placed in the off-hook state, it is considered that a directly connected telephone set 2 is placed in the off-hook state, a timer 16 clocks the time to detect the remote signal only for a certain time, and when the remote signal is present, it is detected by a detecting means 12 through a monitor means 8 and outputted to the means 17. When the remote signal is detected, a telephone line 1 is closed and a facsimile reception state is entered. When the off-hook state of the telephone set 5 is detected, the remote signal is detected until the telephone set 5 is placed in the on-hook state and the line 1 is closed in response to the presence of the remote signal, so that the equipment enters the facsimile reception state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having a remote receiving function.

[0002]

2. Description of the Related Art Conventionally, a facsimile apparatus has been used as an apparatus for transmitting and receiving an image signal via a telephone line. Since such a device has been downsized and the price has been reduced, it has been popularized in general households. In general household use, since a facsimile machine and a telephone are usually connected to one telephone line, the facsimile machine is provided with a function for connecting the telephone.

One of them is a remote receiving function as shown in Japanese Patent Application Laid-Open Nos. 5-75770 and 5-153322. This function is a function to start fax reception without directly operating the facsimile device when a simple remote signal (for example, dial "*, 9") is sent from the telephone attached or the telephone directly connected to the telephone line. .

[0004]

However, as shown in FIG. 3, when the same facsimile is used, the remote code number set at the time of shipment remains the same and the remote telephone is directly connected to the telephone set or the telephone line directly connected to the telephone line. Even if a signal is transmitted to receive a fax, the partner facsimile machine that tried to send the fax also receives the fax.

The present invention solves the above-mentioned conventional problems, and provides a facsimile apparatus which can appropriately judge a remote signal from a telephone attached to a telephone or a telephone directly connected to a telephone line to receive a fax. Is intended.

[0006]

In order to achieve this object, a facsimile apparatus of the present invention uses a ring signal detecting means for detecting a ring signal input from a telephone line and a ring signal detecting by the ring signal detecting means. An interface means for responding to close the telephone line, a facsimile signal sending means and a facsimile signal receiving means, an off-hook detecting means for detecting an off-hook of the attached telephone, and an ID.
A storage unit that stores a code, a monitoring unit that monitors a signal transmitted from a telephone set side by side or a telephone that is directly connected to the telephone line even when the interface unit opens the telephone line, and a remote signal is detected. After the ring signal is detected by the remote signal detecting means, the remote signal detecting means detects the remote signal transmitted from the side telephone or the telephone directly connected to the telephone line and controls the facsimile signal to be received.

[0007]

According to the present invention, in the above configuration, when the remote reception code is detected, if the ring signal is detected before the remote signal is detected, it is detected whether the attached telephone is in the off-hook state, and the off-hook state is detected. If it is, the fax signal is received, and if the attached telephone is on-hook, the remote signal is received and the fax signal is received only for a certain period of time after the ring signal is stopped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a block diagram showing the configuration of a facsimile apparatus of the present invention, and FIG. 2 is a flow chart showing its operation.

In FIG. 1, 1 is a telephone line, 2 is a telephone directly connected to the telephone line 1, 3 is a jack for connecting a facsimile machine, 4 is a jack for connecting an attached telephone, 5 is an attached telephone, 6 is a ring signal detecting means for detecting a ring signal input from the telephone line 1, 7 is an interface means for closing the telephone line 1 when receiving a fax, and 8 is an attached telephone 5 or a directly connected telephone 2. Is a monitor means for detecting a remote signal of the above, 9 is an off-hook detecting means of the side-by-side telephone 5, 10 is a facsimile signal sending means, and 11 is a facsimile signal receiving means.

Reference numeral 12 is a remote signal detecting means for detecting a remote signal input from the interface means 7 or a remote signal input from the monitor means 8 after the interface means 7 has closed the telephone line 1, and 13 is an image reading means. Reference numeral 14 is a printing means. 15 is an operating means, 1
Reference numeral 6 is a timer, 17 is a control means for controlling each part according to each signal, a predetermined procedure (shown in FIG. 2), a command inputted by the user, and the like, and 18 is a storage means. The remote code is stored in this storage means 18. The control means 17 causes the facsimile signal reception means 11 to perform facsimile reception when the remote signal detected by the remote signal detection means 12 matches the remote code stored in the storage means 18.

The operation of the facsimile apparatus configured as described above will be described in detail below with reference to the flowchart of FIG.

First, the ring signal input from the telephone line 1 is detected by the ring signal detection means 6 and output to the control means 17 (step 1). When the ring signal detection is input a predetermined number of times (step 2), the control means 17 automatically closes the telephone line (step 3) and enters a facsimile signal receiving state (step 4).

If the ring signal detection is stopped without being input a predetermined number of times, the control means 17 detects whether the off-hook telephone 5 is off-hook by the off-hook detecting means 9 of the on-off telephone (step 5). When the attached telephone 5 is not off-hook, the directly connected telephone 2 is considered to be off-hook, and the remote signal is detected only for a certain period of time counted by the timer 16 (step 6). When the remote signal is sent from 2, the remote signal detection means 12 detects it through the monitor means 8 and outputs it to the control means 17. When the remote signal is detected, the facsimile device closes the telephone line 1 (step 3) and enters the facsimile receiving state (step 4).

When it is detected in step 5 that the attached telephone 5 is off-hook, the remote signal is detected until the attached telephone 5 is hooked on (steps 7 and 8). When a remote signal is sent from the telephone 5 attached to the remote station, the remote signal detecting means 12 is passed through the monitor means 8.
And is output to the control means 17. When the remote signal is detected, the facsimile device closes the telephone line 1 (step 3) and enters the facsimile receiving state (step 4). The remote signal is the dial button on the phone.
It may be a DTMF signal generated by pressing "1".

[0015]

As is apparent from the above description, according to the present invention, if the remote signal detecting means detects the remote signal through the telephone line and the remote signal detecting means detects the ring signal before detecting the remote signal. Whether the remote signal is from a telephone directly connected to the telephone or the telephone line by providing a storage means for storing the telephone number and an off-hook detection means for the telephone which is connected to the telephone to detect whether the telephone is off-hook. You can judge whether it is a signal from the other party.

As a result, when an attempt is made to operate the remote receiving function of the facsimile apparatus, it is possible to prevent a product having the same function, which is intended to be fax-transmitted by the remote signal sent to the line, from having the function of fax-receiving. Only a facsimile machine for the purpose of receiving can receive a fax.
