Abstract
An electronic apparatus and a power supply device used with the electronic apparatus is capable of automatically shutting off power from a power supply to the electronic apparatus when an access cover is opened. The electronic apparatus includes a casing that houses a power control unit therein, and having one end open, an access cover disposed at the casing to open and close the open side of the casing, and a power supply device that connects an external power source to the power control unit. The power supply device shuts the power control unit off from the external power source when the open side is open. Accordingly, when the access cover is opened for the operations such as additional installation of the optional item or replacement of inner parts with new ones, the external power supply is automatically shut off. Therefore, accidents such as electrocution or burns, can be prevented, and damage to the electronic apparatus caused by the electrical shock can also be prevented.
