PROBLEM TO BE SOLVED: To prevent a resource from being left in a system without being released when a task disappears in an information processor to be driven by multitask. SOLUTION: When resource security is requested, a resource relating part 31 registers correspondence information between a task and a resource in task control information 11 and a resource management information 12. When task disappearance is requested, a task control part 21 releases a resource registered correspondingly to a task allowed to disappear by using a resource release part 23. When a security request for an already secured resource is generated, a re-security control part 33a releases the specified resource by using the resource release part 23 and a resource security part 22 when the priority of the current security request is higher than that of a previous security request and the resource can be released, and secures the released resource in a specified task.
