Abstract
In a data processing device, when exchanging a plug-in package with another without breaking the power to be supplied to the data processing device, a package removing lever is equipped with a locking piece. The lever does not move and the package hence cannot be removed, until the locking piece is released. In response to the release operation of the locking piece, a switch is activated to break off the power supply for the package. After the package is mounted perfectly, the power for the package is switched on by the action of the locking piece, thus preventing any misoperation when removing the package.
