A remote-operated unit of a user terminal apparatus remote-operated through network from a remote terminal apparatus of a support staff sends image information of a changed portion to the remote terminal apparatus to display a business screen in an interlocked manner when a change is detected in the business screen displayed by a business processing unit with an image-information transmission unit. When an operation-information reception unit receives remote operation information of a mouse or keyboard from the remote terminal apparatus, a remote-operation prohibited region management unit refers to a remote-operation prohibited region table and prohibits remote operation if the remote operation information is within the operation prohibited region.
