Abstract: The present invention relates to a mounting-state display apparatus for displaying the mounting-states of devices. Particularly, the present invention provides a mounting-state display apparatus enabled to automatically generate a display, indicating the mounting-states of various kinds of packages in the devices, which is not limited to a specific device, by using an NE-OPS for managing the devices. This mounting-state display apparatus comprises a device component database, for holding device components, which represents a mounting state of an arbitrary one of the devices as original picture elements of a minimum configuration required to indicate a mounting-state display and an application program portion for accessing the device component database and for generating a display indicating the mounting state of a specific one of the devices by performing operations of placing the original picture elements and changing the size thereof.
