When the control board 40 is replaced, the information specific to the equipment stored in the board 40 before the replacement is maintained and registered simply again after the replacement of the board.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is useful for preserving information unique to an image communication device such as a facsimile when the control board in the device is replaced for repair or the like. related to information security equipment.

Conventional technology For example, in an image communication device such as a facsimile, R is used to store device-specific information that differs for each user, such as destination information, communication management information, setting parameters, etc.
It has AM (Random Access Memory).

On the other hand, in the above-mentioned device, in order to facilitate maintenance etc.
The above RAM along with the CPU (Central Processing Unit)
Mounting is performed on a board that is replaceably mounted within the device. Thereby, if a failure or the like occurs in the control function section, it can be dealt with simply by replacing the board.

Problems to be Solved by the Invention However, with this configuration, there is a problem in that when the control board is replaced for repair or the like, information specific to the device is lost and re-registration becomes extremely troublesome. Ta.

The above problem arises for the following reasons.

In other words, the control board before replacement stores device-specific information that differs for each user, such as destination information, communication management information, setting parameters, etc., using the RAM mounted on the board. However, the new control board after replacement does not store the above-mentioned device-specific information.

Therefore, after replacing the control board, it becomes necessary to perform the troublesome work of re-registering destination information and the like. Unfortunately, the communication management information cannot be re-registered and is lost when the board is replaced. As described above, it is very troublesome and difficult to re-register the device-specific information held before the board was replaced after the board is replaced.

The present invention has been made in view of the above-mentioned problems, and when a control board in a device is replaced for repair or the like, the device-specific information stored in the board before replacement is preserved, and the board is replaced. It is an object of the present invention to provide an information security device that allows easy re-registration later.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a storage means for storing stored information in a control board replaceably mounted in the device outside the device, The device is configured to be connected to an address bus, a data bus, and a control bus in the control board via detachable connection means.

Effects The present invention has the above-described configuration to extract device-specific information stored in a control board inside the device and store it in storage means outside the device, and to store information held in the storage means outside the device in the device. When replacing the control board inside the device for repairs, etc., the information unique to the device stored on the board before replacement can be preserved and the board replaced. You can easily re-register later.

The operation of the information security device configured as described above will be explained below.

1. When replacing the control board 40 for equipment repair, etc., the ROM 36 in the control board 40 before replacement is
Remove it from C socket 11.

Next, the IC socket adapter 10 of the information security device is inserted into the IC socket 11 from which the ROM 36 has been removed.

In this state, if the operator sets the switch on the memory board side to the information download state, commands based on this setting (
SW) is connected to the bus (A-) on the memory board side by Pi024.
bus + D-bus) and is transmitted to the CPU 35 in the control board 40 via the IC socket adapter 10 and the IC socket 11.

Having received the command, the CPU 35 in the control board 40 reads out the information stored in the RAM 37 of the control board 40 from the ROM 21 in the storage board, and reads out the information stored in the RAM 37 of the control board 40.
The first transfer program to be written to is sucked up. This downloaded first transfer program is then executed.

As a result, the unique information stored in the RAM 37 of the control board 40 before replacement is transferred to the RAM 2 of the storage board via the IC socket 11 and the IC socket adapter 10.
Transferred to 2. In other words, the information stored in the control board 4° is taken up to the RAM 22 in the storage board and maintained.

When the transfer by the first transfer program is completed, the operator removes the IC socket adapter 10 and replaces the control board 40 with a new one. Then, the ROM 36 of the replaced new control board 40 is removed from the IC socket M1, and as in the previous case, after being removed, the IC socket adapter 10 of the information security device is inserted.

In this state, when the operator sets the switch on the memory board side to the information rewriting state, the command (Sw) based on this setting is sent by the Pi024 to the bus (A- bus, D-bus) and is transmitted to the CPU 35 in the control board 40 via the IC socket adapter 10 and the IC socket H1.

Having received the command, the CPU 35 in the control board 4o reads the stored information in the RAM 22 of the storage board from the ROM 21 in the storage board 9, and sucks up the second transfer program to be written in the RAM 37 of the control board 40. Then, this second transfer program that has been downloaded is executed.

As a result, the unique information stored in the RAM 22 of the storage board is transferred to the IC socket adapter 10 button and the I
The data is transferred to the RAM 37 of the control board 4o via the C socket 11. Finally, the unique information stored in the RAM 22 in the storage board 9 is transferred to the RAM 3 in the control board 40.
7 will be re-registered.

Thereafter, by removing the IC socket adapter 10 from the IC socket 11 of the replaced control board 40 and inserting the ROM 36, the replacement of the control board 40 and the re-registration of the unique information are completed.

In the above embodiment, the IC socket 11 of the ROM allows
A-bus, D-bus, C-b of control board 40
Although the configuration is such that the IC socket 11 is connected to the
Anywhere is fine as long as it can be connected to C-bus.

As described above, the device-specific information stored in the control board 40 inside the device is sucked up and held in the RAMZ2 outside the device, and the information held in the RAMn outside the device is transferred to the control board 40 inside the device. The information is then returned to the original location and stored again. As a result, when the control board 40 in the device is replaced for repair or the like, it is possible to preserve the device-specific information stored on the board before replacement and easily re-register it after the board is replaced. .

In the above-described embodiment, the ROM 21 for storing the transfer program, the switch for setting commands, etc. were mounted on the storage board side, but these were mounted on the control board 40 side of the device. You may also do so.

Instead of RAM, EEP-ROM (electrically erasable and writable RO) is used as storage means on the storage board side of the housing.
M) can also eliminate the need for backup batteries.

Effects of the Invention As is clear from the above description, the present invention includes a storage means for storing information stored in a control board replaceably installed in the device outside the device, and this storage means is removably attached. By connecting to the address bus, data bus, button and control bus in the control board through a suitable connection means,
The device-specific information stored in the control board inside the device is sucked up and stored in storage means outside the device, and the information held in the storage means outside the device is returned to the control board inside the device and stored again. Therefore, when replacing the control board in the device for repair or the like, the device-specific information stored on the board before replacement can be preserved and easily re-registered after the board is replaced. This has the effect of
