Information processing apparatus with resume function and information processing system
View Patent ↗An information processing apparatus having a resume function which can maintain the security even when a plurality of users commonly use the apparatus. A work state at a power-off time of the apparatus is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for resume function on a main memory for each user. When a power source is again turned on, data in the preservation area corresponding to the user's ID is used to reproduce the work state of the user at the power-off time. The work preservation areas can be provided on a file server apparatus in a network not needing battery back-up. When the information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each user.
1. An information processing apparatus comprising:
a memory unit;
a display unit; and
a processing unit being adapted to execute a process in accordance with a program stored in the memory unit,
wherein the memory unit having a plurality of work state holding areas for storing information regarding work of the information processing apparatus as a set of states of said processing unit and said display unit, and
wherein said information processing apparatus is adapted to store said information regarding work of the information processing apparatus into one of said a plurality of work state holding areas, and a read information from an arbitrary one of said work state holding areas to reproduce the work state.
2. An information processing apparatus according to claim 1 , wherein said memory unit comprising:
a first memory unit where data stored therein is lost after the power is switched off, and a second memory where data stored therein is hold after the power is switched off, said plurality of work state holding areas are provided in said memory unit,
wherein said processing unit is adapted to execute a process for reproducing the work state regarding the stored information if the power is switched on.
3. An information processing apparatus according to claim 2 , wherein said second memory unit comprising:
a storage-medium without the need of battery backup.
4. An information processing apparatus according to claim 1 , wherein each of said plurality of work state holding areas stores an identifier therein for distinguishing own work state holding area from the other work state holding areas, the identifier is used by a user for designating the work state holding area.
5. A processing apparatus according to claim 4 , wherein the identifier is uniquely associated with a user.
