Description

[Detailed description of the invention] Industrial applications The present invention relates to a facsimile device.

2. Description of the Related Art Conventionally, in order to make effective use of telephone lines, a telephone for making calls and a facsimile communication means for transmitting and receiving image data have been integrally integrated into one telephone line. There is a facsimile device in which the telephone set and facsimile communication means are connected.

When such a facsimile device with a telephone receives a call signal via the telephone line, it closes the telephone line and
Based on the CNG signal transmitted from the calling station, it is determined whether the communication is a call request or a facsimile communication.

When a CNG signal is being transmitted, it is facsimile communication, and in this case, the facsimile device connects the facsimile communication means to the telephone line and outputs a predetermined signal tone to notify the operator that the facsimile has been received. . Thereafter, the image data transmitted by the calling station is received, and the received image data is recorded on recording paper or stored in a memory built into the facsimile machine.

When the CNG signal is not transmitted, it is a call request,
In this case, the facsimile machine connects the telephone to the telephone line and rings the telephone's ringing bell.

Problems to be Solved by the Invention In the conventional facsimile machine as described above, all received image data is recorded on recording paper or stored in memory, so unnecessary image data, such as direct mail by facsimile, is lost. Even if it is, it will be recorded on recording paper and stored in memory. This wastes recording paper and memory, and since recording paper is a burden for the operator of the called facsimile machine, unnecessary image data also costs money, and memory has a limited storage capacity. This may cause a capacity shortage and make it impossible to store necessary image data.

Furthermore, although the penetration rate of facsimile devices is increasing year by year, it is much lower than the penetration rate of telephones. Therefore, the present invention often involves transmitting and receiving image data to and from a specific party. An object of the present invention is to provide a facsimile device that can receive only necessary image data, that is, image data transmitted from a predetermined calling station.

Means for Solving the Problems The present invention provides a facsimile machine that transmits and receives communication conditions including at least a calling party's telephone number to and from a communication partner station prior to transmitting/receiving image data. A telephone number storage means for storing the telephone number of the calling party; a telephone number detecting means for detecting the telephone number of the calling party transmitted from the calling station prior to the image data; and a number determining means for comparing the calling party's telephone number from the number detecting means and determining whether or not the numbers match.

A facsimile apparatus is characterized in that the facsimile apparatus includes receiving means for receiving image data when the numbers match in response to the output of the number determining means.

Function: The facsimile device according to the present invention exchanges the calling party's telephone number,
Communication conditions such as image data transmission speed and recording paper size are exchanged. The telephone number detection means detects a calling party's telephone number from among the communication conditions transmitted from the calling station prior to receiving the image data. Further, the telephone number storage means stores a predetermined calling party telephone number.

The number determining means compares the calling party's telephone number in the telephone number storage means with the calling party's telephone number detected by the telephone number detecting means and determines whether the telephone numbers match.

The receiving means responds to the output of the number 1 discrimination means and receives image data from the calling station when the telephone numbers match.

Therefore, only the image data from the calling facsimile device whose phone number is pre-stored in the facsimile device will be received, thereby preventing the reception of unnecessary image data such as direct mail by facsimile. can.

This eliminates the need to record unnecessary image data on recording paper or store it in memory, eliminating wasteful use of recording paper and reducing the frequency of memory capacity shortages. .
