Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile machine, and more particularly, to a facsimile machine that identifies a special party and performs reception processing.

(Prior Art) In recent years, facsimile machines have become widespread, and their functions are rapidly improving.

For example, facsimile machines have an automatic reception function that automatically receives and records it on recording paper without requiring the operator to press a button each time a reception is received, and a facsimile machine has an automatic reception function that automatically receives a document and outputs it to recording paper without the operator having to press a button for each reception. It has a broadcast transmission function that automatically sends data.

However, as facsimile machines become more widespread and their functions become more sophisticated, while they are convenient, facsimile machines also receive documents that are unnecessary for the recipient of direct mail, etc., and record them on recording paper. As a result, recording paper is wasted and is uneconomical.

Therefore, as described in Japanese Patent Application Laid-Open No. 64-74868, when in reception mode, the telephone number sent from the other party is compared with the telephone number registered in advance in the own memory, and if they match, We will only receive manuscripts from
A facsimile machine has been proposed that refuses reception if the numbers do not match.

Conventionally, there is also a facsimile machine which compares an ID code sent from the other party with an ID code registered in its own memory when receiving a document, and receives the document only if the facsimile machine fails. Conventionally, such a closed area function prevents wasteful use of recording paper by rejecting reception from anyone other than a specific party.

(Problem H to be solved by the invention) However, in such conventional facsimile machines, it is determined whether or not to receive a document based on the recipient's phone number and ID code registered in advance.
The number of parties that can be communicated with is limited to a small number of parties, such as those whose telephone numbers are registered in advance and those whose ID codes are known, making it difficult to effectively utilize the facsimile machine and reducing its usability.

(Purpose of the Invention) Therefore, the present invention performs normal reception processing for incoming calls from a specific party, and receives calls from other parties other than the specific party.
By performing memory reception processing that stores received image data in the image memory, it is possible to prevent waste of recording paper due to unnecessary documents such as gray left mail, and also to receive documents from other parties other than a specific recipient. The purpose of the present invention is to improve the economic efficiency of using a facsimile machine by making it possible to check the contents, and to improve the usability of the facsimile machine.

(Structure of the Invention) In order to achieve the above object, the present invention includes an image memory that stores received image data, a recording section that records the received image data on recording paper, and a system that identifies only transmissions from a specific party. A facsimile machine is equipped with a function to identify a destination to receive a call from, and when a call is received from the specific destination, it performs normal reception processing of recording the received image data on recording paper, and then identifies the destination. For calls from other parties,
It is characterized by performing memory reception in which received image data is stored in an image memory.

Hereinafter, the present invention will be specifically explained based on examples.

FIG. 1.2 is a diagram showing an embodiment of the present invention.

FIG. 1 is a block diagram of a facsimile machine 1, which includes a scanner 2, a block 3, an operation section 4,
A/D conversion section 5, buffer memory 6, compression/reproduction section 7,
It includes a modem 8, a network control section 9, a memory IO, a system control section 11, and the like.

As the scanner 2, for example, COD (Charge
A line scanner using a coupled device is used, and the scanner 2 reads the document line by line and outputs it as image data.

The plotter 3 uses, for example, thermal recording transmission using a thermal element, and the block 3 records directly on thermal recording paper or indirectly on ordinary recording paper via an ink sheet.

The operation unit 4 is equipped with various keys such as a start key, a numeric keypad stop key, and a display unit.The operator inputs commands by operating various keys, and the display unit allows input commands and the operator to input commands from the facsimile machine 1. Display various messages to be transmitted.

The A/D converter 5 converts analog image data output from the Skikina 2 into digital data.

The buffer memory 6 stores the image data digitally converted by the A/D conversion section 5 for a predetermined line and transfers it to the compression/reproduction section 7, and also stores the image data sent from the compression/reproduction section 7 for a predetermined line. It is stored and transferred to the plotter 3.

The compression/reproduction unit 7 encodes (compresses) image data using a predetermined encoding method, and also decodes (reproduces) the encoded data.

Modem 8 modulates the transmitted signal and demodulates the received signal.

An external line (for example, a public telephone line) L and a telephone set 12 are connected to the network control unit 9, and the network control unit 9
It performs switching control to switch between the main body of the facsimile machine 1 and the telephone set 12, and performs automatic light and call processing.

The memory 10 has a predetermined capacity.

Numbers etc. are memorized. This destination ID code and the like are input by key operations on the operation unit 4 and are registered in the memory 10 in advance.

The system control unit 11 is a CPU (Central P
processing unit), ROM (Read
0nly Mea+ory) and RAM (Ran
dom Access Memory), etc., and RO
A basic program for the facsimile machine 1, a reception processing program of the present invention, etc. are stored in M. The system control section 11 controls each section of the facsimile apparatus 1 according to a program in the ROM to execute the sequence of the facsimile apparatus 1, and also executes the reception process of the present invention. Further, during facsimile communication, the system control unit 11 generates a facsimile control signal to be transmitted and analyzes a received facsimile control signal.

During facsimile communication, the facsimile device 1 modulates the facsimile control signal generated by the system control section 11 using the modem 8 and sends it to an external line via the network control section 9, and controls the facsimile control signal received via the network control section 9. After the signal is demodulated by the modem 8, it is analyzed by the system control unit 11 and a facsimile control procedure is executed. A facsimile device 1 reads a document with a scanner 2, and immediately transmits image data of the read document to an A/D converter 5 and a buffer memory 6.
The data is sent to the compression/reproduction unit 7 via the compression/reproduction unit 7, where it is encoded and then transmitted. In addition, in memory transmission, the image data encoded by the compression/reproduction unit 7 is temporarily stored in the memory 10, and read out from the memory 10 at a predetermined transmission time or immediately and encoded as is or re-encoded using a predetermined encoding method. Send.

On the other hand, when facsimile apparatus 1 receives data, in the normal reception mode, the received image data is decoded by compression/reproduction unit 7, sent to plotter 3 via buffer memory 6, and recorded on recording paper in block 3.

In addition, in memory reception, the received image data is
Or it is re-encoded by the compression/reproduction unit 7 and stored in the memory 10.
Once stored, the data is read out from the memory 10 at a predetermined time or when a predetermined output operation is performed on the operation unit 4, decoded by the compression/reproduction unit 7, and then sent to the block 3 via the buffer memory 6.

The plotter 3 records on recording paper.

Next, the effect will be explained.

The present invention is characterized in that reception is performed by switching the reception method between a normal reception mode and a memory reception mode depending on the destination. This reception process will be explained below based on the flowchart of FIG. 2.

When the facsimile machine 1 receives an incoming call, the system control unit 11 instructs the network control unit 9 to off-hook the line.
F (S), NSF (C3I)), called terminal identification signal (C3I), digital identification signal (DIS), etc. are sent at predetermined intervals, and the ID code or transmitting terminal identification signal is received from the other party within a predetermined time. (TSI signal), digital command signal (DO3), non-standard function setting signal (NSS
(S), N5S (TSI)), etc. is received (steps 83 to 36).

When transmitting an ID code, the recipient's facsimile machine either transmits a predetermined ID code as a DTMF signal by the operator using the numeric keypad of the facsimile machine, or sends it as a DTMF signal using an ID pre-registered in the memory.
The code is converted into a DTMF signal and transmitted under the control of the system control unit.

Furthermore, when using a C3I signal or an RTI signal to select a specific communication partner, the destination facsimile device sends the C8I signal with a telephone number or password, or the RTI signal with the name of the own station or a code. and send.

On the other hand, when the facsimile machine 1 on the receiving side receives the ID code, the system control unit 11 stores the memory 1 in advance.
Step S to check if it matches the ID code registered in 0? ), when the ID codes match, it is determined that the destination is a specific party for which reception is permitted, and normal reception processing is performed, that is, reception processing in which the received image data is immediately sent to the plotter 3 and recorded on recording paper. Therefore, it is possible to promptly respond to urgent documents from a specific recipient, and the usability of the facsimile machine 1 is improved.

On the other hand, step S? If the ID code does not match,
It is determined that the destination is not a specific destination, and memory reception processing, that is, reception processing for storing received image data in the memory 10, is performed. Therefore, it is possible to prevent the recording paper in block 3 from being wasted due to reception from parties other than a specific recipient such as direct mail, and to take into account the need for documents even if the recipient is not a specific recipient. The received image data can be stored in the memory 10.

Also, if the ID code is sent within the specified time, the TS
Upon receiving a facsimile control signal such as an I signal or an NSS signal, the system control unit 11 performs a C
Analyze the 3I signal or RTI signal and check whether the telephone number, PIN number, name of your station, code, etc. match the contents registered in advance in the memory 10 (step Sa). If they match, normal reception is performed. processing,
If they do not match, memory reception processing is performed.

Further, when neither the ID code nor the facsimile control signal is received within a predetermined period of time (steps 83 to S), the line is turned on-hook (the line is determined) (step S9), and the process returns to the standby state.

Note that the image data received through memory reception is read out from the memory 10 by the operator operating a predetermined key from the operation unit 4, decoded by the compression/reproduction unit 7, and then
The data can be recorded on recording paper by the plotter 3 via the pub sofa memory 6.

At this time, the operator checks the content recorded on the recording paper and if the document is necessary, allows all pages to be recorded as is.
It is possible to record and output the required original on recording paper even if it is not a specific recipient. Furthermore, if the recorded content is determined to be unnecessary, recording can be stopped by pressing a predetermined key on the operation unit 4, such as pressing the stop key, thereby preventing wasted use of recording paper. can do.

Furthermore, the image data in the memory 10 can be erased for each communication or the like by operating a predetermined key on the operation unit 4, so that the usability of the memory 10 can be improved.

Also, when memory reception is received when the destination is not a specific destination,
If you read out the telephone number and name of the other party from the C3I signal or RTI signal of the other party and display it on the display section of the operation unit 4, or record the telephone number and name of the other party in the reception report, it will be printed on the recording paper. It is possible to easily determine whether the document is necessary or not based on the reception report without recording the contents of the document, and recording paper can be further saved.

Furthermore, in the above embodiment, the ID code, C3I signal, and RTI
Although both signals are checked, the other party may be determined based on only one of them.

(Effects) According to the present invention, it is possible to carry out the normal reception process of recording and outputting a document from a specific party on recording paper, and also to receive in memory a document from a party other than the specific party, such as a guilef mail, and its contents. This makes it possible to prevent wasteful use of recording paper due to unnecessary original documents, thereby improving the economic efficiency of using the facsimile machine and improving the usability of the facsimile machine.
