PURPOSE:To avoid loss of reference information relating to communication by storing the information in a memory storing the information referenced in the case of communication with a communication destination party into a nonvolatile storage device and reading the stored information from the memory with a prescribed command. CONSTITUTION:An opposite telephone number or the like inputted is stored in a registration area 3a of a RAM 3 while being related to an abbreviation number (as a table). When a 'registration data save key' on an operating panel 4 is depressed, the data registered in the registration area 3a of the RAM 3 is written to a predetermined directory (or in file name) of a hard disk 11. Thus, an unexpected event takes place and the data registered so far in the registration area 3a is lost, the data is preserved in the hard disk 11 without loss and the secure saving is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data communication device, and more particularly, to a data communication device typified by a facsimile device that transmits and receives images.

[Prior Art] In many modern facsimile machines, the telephone numbers and the like of the facsimile machines with which they communicate frequently are often registered in the back-up memory of the facsimile machines themselves.

This allows you to - without having to enter the phone number.
With just a few keystrokes, you can call the other party and transfer the call.

[Problems to be Solved by the Invention] By the way, when storing various data such as the telephone number of the other party in the backup memory, it is normal to provide some kind of protection circuit for the data stored inside. . Normally, this has been dealt with by providing a circuit for the backup memory that prohibits the output of memory write signals except for processing such as registration.

However, if a failure occurs in the circuit itself that includes the backup memory, there is a problem in that the contents of the backup memory will be erased when some parts are replaced or the battery is removed for a circuit check.

The present invention has been made in view of this problem, and it is an object of the present invention to provide a data communication device that makes it possible to solidify the maintenance of various information related to communication.

[Means for Solving the Problem] A data communication device of the present invention that solves this problem has the configuration shown below. That is, there is a memory for storing information to be referred to when communicating with a communication partner, a storage means for storing the information in the memory in a non-volatile storage device, and a storage means for storing the information stored in the storage means according to a predetermined instruction. and reading means for reading data into the memory based on the memory.

[Operation] In the configuration of the present invention, the storage means stores information to be referred to when communicating with a communication partner from the memory to the nonvolatile memory. Then, when a predetermined instruction is given, the saved information is read out to the memory.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows Noah in this embodiment. A block diagram of the Kushimiri device is shown.

In the figure, 1 is a CPU that controls the entire device. Reference numeral 2 denotes a ROM which stores programs relating to the flowchart of FIG. 2, which will be described later, in addition to communication-related processing processed by the CPUI. 3 is a RAM, which is used as a work area for the CPUI, and also stores the telephone number of the other party, the abbreviation of the other party, the abbreviation of the machine, the telephone number of the machine, and memory switches for selecting functions of this device. It is provided with a registration area 3a for storing information. Reference numeral 4 denotes an operation panel equipped with a group of keys for performing various operations, and has a display section 5 (made of liquid crystal or the like) for displaying various messages and the like. Reference numeral 6 denotes a communication control unit that controls the connection between the device and the line, and data is transmitted and received through this unit. Reference numeral 7 indicates a printer section for reading the original image, and reference numeral 8 indicates a printer section for visually recording the received image and the like. Reference numeral 9 denotes an encoding/decoding section that encodes image data read from the league section 7 and decodes data received via the communication control section 6. 10 is an image memory for storing received data, read data from the reader 7, etc.; 11 is a hard disk device having a larger capacity than the image memory 10;

An overview of the main operations of this device with the above configuration will be explained below.

As described above, the registration area 3a can store a plurality of telephone numbers of other parties as long as the memory capacity allows.

Now, when registering a new destination phone number, etc., by operating the keys on the operation panel 4, input the destination phone number and its abbreviation, as well as the abbreviated number assigned to it. etc. (The input contents are displayed on the display unit 5 so that they can be confirmed). The destination phone number, etc. entered in this way is associated with that abbreviated number (
(as a table) is stored in the registration area 3a of the RAM 3.

However, in this state, if an unexpected device failure or power outage occurs, the data registered in the registration area 3a of the RAM 3 will be lost. Therefore, in this embodiment, a "registered data save key (not shown)" is provided in the operation panel 4. When this "registered data save key" is pressed, the registered data is saved in the registration area 3a in RAMa. The data is written to a predetermined location on the hard disk 11 (or with a file name).

By doing this, even if an unexpected situation occurs and the data registered in the registration area 3a disappears, it will remain stored in the hard disk drive 11, making it safe. It can be done.

In addition, when reading out the registration data saved in the hard disk device 11 to the registration area 3a again, the operation panel 4
This can be achieved by pressing the "registered data load key (not shown)" provided in the .

According to the above processing outline, the operation contents of CPU I are shown in the flowchart shown in FIG.

First, in step S1, a key input from the operation panel 4 is waited for. When key human power is detected, proceed to step S2,
It is determined whether the input key is a registered data save key. If the registered data save key has been pressed, the process proceeds to step S3, where all data registered in the registration area 3a of the RAM 3 is saved in the hard disk device 11, and the process returns to step Sl.

If it is determined that the input key is other than the registered data save key, the process proceeds to step S4, and it is determined whether the input key is the registered data load key. In the case of a registered data load key, the process goes to step S5.
Then, the registration data stored in the hard disk device 11 is loaded into the registration area 3a of the RAM 3.

On the other hand, if it is determined that a key other than the registered data load key has been pressed, the process proceeds to step S6, and the process (for example, data transmission) corresponding to the input key is executed.

If there is an incoming call during the above-mentioned processing, the data will be received and printed out using interrupt processing.

As explained above, according to this embodiment, registration data such as the telephone number of the other party can be stored in the hard disk device 11 and loaded into the RAM as necessary, so that the data will not be lost. In other words, when a road failure occurs in the device, it is possible to eliminate the work of re-registering data after repairing the fault, and in some cases, it is possible to shorten the work time.

In the embodiment, it has been explained that when saving data in the registration area of the RAM 3 to the hard disk device 11 or conversely loading the data, a dedicated key is pressed. However, a dedicated key to execute these is not necessarily required. This is because when key operations are performed in accordance with the message displayed on the display unit 5, other keys can be used instead. In particular, when registering a new telephone number of the other party, if the registered data is automatically additionally saved on the hard disk drive 11 just by performing the normal registration operation, the registered data can be saved specifically on the hard disk device 11. It is convenient because the storage process can be executed without having to be conscious of doing so.

Further, although the embodiment has been described using a facsimile machine as an example, the present invention is not limited to this, as it may be any device that communicates with a destination terminal via a line.

[Effects of the Invention] As explained above, according to the present invention, reference information related to communication will not disappear.
