Patent attributes
A digital multifunctional device 1 comprises a control panel 20 with a LCD panel 20 for manipulating various settings, an auxiliary memory 7b for temporarily storing the image data to be processed, an image data destruction means for destructing the image data stored in the auxiliary memory 7b, and an operation restriction means for restricting the image data processing operation. When the digital multifunctional device 1 is to be replaced or discarded, the image data destruction means destructs the image data stored in the auxiliary memory 7b. When the stored image data is destructed by the image data destruction means, the operation restriction means restricts the subsequent image data processing operation and notifies the completion of destruction to a specified administrator.
