Abstract

PURPOSE:To omit an expensive magnetic card reader by comparing an identification number stored in a nonvolatile memory device with an identification number inputted by a ten-key and making a facsimile equipment into the operationable state only when they are coincident. CONSTITUTION:A set key 20 is provided in the function keys of a conventional keyboard 9. A regular user uses the ten-key of the keyboard 9 to input its own identification number and depresses the key 20 finally. A main control section 1 reads the identification number through the depression of the key 20 to check whether or not the identification number is coincident with the identification number stored in a ROM 12. If coincident, it is recognized the user is a prescribed user, the facsimile equipment is brought into the operationable state, and when dissident, the operation of the facsimile equipment is not allowed. Thus, the expensive magnetic card reader is omitted.

Description

[Detailed Description of the Invention] [Summary] A set key is provided on the keyboard of a facsimile machine, and the user presses the set key after inputting an identification number using the numeric keys on the keyboard before using the machine. By doing this, a comparison with a designated identification number built into the facsimile device is automatically performed, and the facsimile device is enabled to operate only when there is a match, thereby performing individual management of the facsimile device.

[Industrial application field]

The present invention relates to a facsimile device with a security function.

[Conventional technology]

For example, when multiple facsimile machines are installed and operated within a single office, it has been common practice to manage them individually.

The individual management referred to here means that the users within the business office are divided into multiple groups.For example, group A uses facsimile machine A, group B uses facsimile machine A, etc. This is a management method that involves checking the frequency of use for each facsimile machine and recording usage costs. For this purpose, it has conventionally been common to use magnetic cards.

FIG. 3 is a diagram showing an example of individual management using a conventional magnetic card.

In the figure, 1 is a main control unit, 2 is a transmission document, 3 is a transmission document reading unit, 4 is a compression/decompression unit, 5 is a modem, 6 is a line control unit,
7 is a file, 8 is a recording unit, 9 is a keyboard, 10 is a magnetic card, 11 is a magnetic card reader, and 12 is a ROM. The same symbols represent the same objects throughout all the figures below.

FIG. 3 shows an example of the equipment configuration of a facsimile machine having a so-called storage device (file 7).

That is, in the case of transmission, the content of the transmission document 2 is read by the transmission document reading section 3 under the control of the main control section 1 to create so-called image data, and this image data is sent to the compression/decompression section 4.
send to Here, the signal is converted and compressed into a predetermined code in order to increase transmission efficiency, and further converted into a signal format suitable for transmission in the modem 5, and then sent to the line side via the line control section 6.

In the case of reception, when the line control unit 6 under the control of the main control unit 1 finds that its own device is being called, the modem 5 converts the received message to the original signal format, and then stores the received message in the file 7. Store. When printing out, the received message is read out from the file 7, restored to the original image data in the compression/decompression section 4, and the recording section 8 is driven to print it on recording paper.

The above is an overview of the operation of a facsimile machine having a storage device.

When individually managing facsimile machines of this type, the conventional method is to give each facsimile machine user a magnetic card 10 (ID card) with an identification number written in advance. put.

The facsimile machine is also provided with a magnetic card reader 11 to read the contents of the magnetic card 10, and is further provided with a non-volatile storage device such as a ROM 12 in which the identification numbers of all users are stored.

When a user uses a facsimile machine, he or she first inserts his or her magnetic card 10 into a reader 11. Through this operation, the reading device 11 reads the identification number written on the magnetic card 10.

The main control unit 1 checks whether the read identification number matches the identification number stored in the ROM 12.

If they match, the main control unit 1 recognizes that the user is the specified user, and puts the facsimile machine into an operable state. If there is a mismatch, the facsimile machine will not become operational.

Conventionally, facsimile machines have been individually managed using the magnetic card 10 as described above.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional method, it is necessary to equip each facsimile machine with a magnetic card reading device, and this reading device is expensive, so the cost is also high. had the disadvantage of not being able to use facsimile machines.

c. Means for Solving Problems] FIG. 1 is a diagram showing the principle of the present invention. In the same figure, the above-mentioned problem arises in a facsimile machine having an individual management function that holds a non-volatile storage device 12 in which a user's identification number is stored and a keyboard 9. As shown in FIG. A set key 20 is provided on the keyboard 9, and after the user presses the numeric keys on the keyboard 9 and inputs the identification number, by pressing the set key 20, the identification number and numeric key stored in the non-volatile storage device 12 are set.・This problem is solved by comparing the identification numbers entered using the keys and enabling the facsimile machine to operate only when they match.

[Effect]

According to the present invention, there is no need to input an identification number using a magnetic card;
Since the identification number is checked by pressing the set key 20 after inputting the identification number by pressing the numeric keys on the keyboard 9, there is no need for a magnetic card or an expensive magnetic card reading device, and it is reliable. This has the effect of allowing individual management to be carried out.

〔Example〕

FIG. 2 is a diagram showing an embodiment of a facsimile apparatus with a security function according to the present invention.

In the figure, 20 is a set key.

In the present invention, a set key 20 is provided in the funxidine key of the conventional keyboard 9.

It is assumed that the identification number of the user of the facsimile machine is already stored in the ROM 12 as described in the section of the prior art.

In the present invention, the authorized user uses the numeric keys of the keyboard 9 to input his or her identification number, for example, a four-digit number or symbol, and finally presses the set key 20.

When the set key 20 is pressed, the main control unit 1 reads the four-digit identification number and checks whether it matches the identification number stored in the ROM 12.

If they match, it is recognized that the user is the predetermined user and the facsimile machine is made operational; if they do not match, the facsimile machine is not made operable. By doing this, an expensive magnetic card reader can be omitted.

〔Effect of the invention〕

As explained in detail above, according to the present invention, there is no need to equip each facsimile machine with an expensive magnetic card reader, and even if the facsimile machine does not have a magnetic card, it is possible to input its own identification number from the keyboard. This has the great effect of allowing facsimile machines to be used freely without causing any problems in terms of individual management.
