INFORMATION LOSS PREVENTION DEVICE OF ELECTRONIC EQUIPMENT

To provide an information loss prevention device of electronic equipment that allows miniaturization with a relatively simplified structure and is also more low-cost than a conventional device.SOLUTION: An information loss prevention device 10 of electronic equipment for replacement of a battery 32 in the electronic equipment or a device where the electronic equipment is installed, and a vehicle 30 where the electronic equipment is installed has a back-up power source 12 and a connection means 14 to an electrical load part 34 in the electronic equipment or the device, and the vehicle 30. It comprises a reverse current prevention means 16 that is located between the back-up power source 12 and the connection means 14 and lets current pass from the side of the back-up power source 12 to the side of the connection means 14, and a back-up current application check means 18 that is activated due to current flowing downstream of the reverse current prevention means 16.SELECTED DRAWING: Figure 1 【課題】比較的簡易な構成とすることで小型化を可能とし、かつ従来品に比べて安価な電子機器の情報喪失防止装置を提供する。【解決手段】電子機器または、前記電子機器を搭載した装置、および前記電子機器を搭載した車両３０におけるバッテリ３２の交換時における電子機器の情報喪失置防止装置１０であって、バックアップ用電源１２と、前記電子機器または前記装置、および車両３０における電気的負荷部３４への接続手段１４と、を有し、バックアップ用電源１２と接続手段１４との間に、バックアップ用電源１２側から接続手段１４側への電流を通過させる逆電流防止手段１６と、逆電流防止手段１６の下流側に流れる電流に起因して起動するバックアップ電流通電確認手段１８と、を備えることを特徴とする。【選択図】図１
