FIG. 1 is a block diagram of a conventional memory board device. In the drawing, 1 is a memory board, 2 is a memory, and 3 is a backup battery. Both the memory 2 and the bank-up battery 3 are attached to the memory board 1. Power is supplied to the memory 2 from the battery 3, and the main power is supplied through the connector part 4. The internal wiring is designed so that power is supplied from the battery 3 (t' in the figure), and even if the memory board 1 is disconnected from the main power supply, power can be supplied from the battery 3 to the memory 2 to prevent the memory contents from being destroyed. (made non-luminescent).

いう方法を採らざるを得なか′２．た。However, when the battery reaches the end of its lifespan and is replaced, the memory contents are destroyed. Therefore, the conventional method is to transfer the memory contents to another spare memory board device, replace the battery, and then transfer the memory contents again from the spare memory board device to the memory board device whose battery has been replaced. I have no choice but to take it'2. Ta.
本発明は、このような欠点を解消し、メモリ内容を破壊
せｒｌしかも容易に電池交換できるメモリボード装置の
提供を目的とする。SUMMARY OF THE INVENTION It is an object of the present invention to provide a memory board device that eliminates these drawbacks, allows memory contents to be destroyed, and allows easy battery replacement.
第２図は本発明によるメモリボード装置の構成図である
。図中１〜４は第１図と同じ部分を示す。FIG. 2 is a block diagram of a memory board device according to the present invention. In the figure, 1 to 4 indicate the same parts as in FIG.
５はメモリボードに付けたコネクタ、６はリード線７に
取付けたコネクタで５を６に、又６を５に挿入するよう
にして電気的に接続するもの、フは電池３とコネクタ６
とを接続するリード線である。5 is a connector attached to the memory board, 6 is a connector attached to lead wire 7, which is electrically connected by inserting 5 into 6 and 6 into 5; F is the connector between battery 3 and connector 6.
This is the lead wire that connects the

め、容易にできるという効果が得られる。That is, when it becomes necessary to replace the battery 3 due to the end of its life, etc., insert the four parts of the memory board l into the main power supply, disconnect the connectors 6 and 5 while receiving power from the main power supply, and replace the connector of the new battery 3. 6 is inserted into 5 so that power is supplied to the memory 2 from the battery 3, the memory board 1 is disconnected from the main power supply, and a new battery 3 is replaced with the old battery 3 and the memory board l. Therefore, even when replacing the battery, power is always supplied to the memory 2 from either the main power supply or the battery, so the memory contents are not destroyed, and the battery replacement can be done without the memory board 1 being the main power source. Since this can be done while unplugged from the power source, it has the advantage of being easy to do.
