Abstract:
A reporting system capable of reporting the end of a scanning session to a user through existing computer peripheral devices is proposed. By reporting at the end of a scanning session, the user can proceed with subsequent scanning operations with no delay. Hence, idle time of the scanner is greatly reduced.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an end-of-scan reporting system. More particularly, the present invention relates to a system that reports the completion of a scanning session to a user through computer peripheral components. 
     2. Description of the Related Art 
     Due to progress in multi-media technologies, advanced image processing techniques have lead to the development of many peripheral image processors. A scanner is one of the imagining processors that have recently become an indispensable piece of equipment. Developed from earlier versions of the black-and-white palm top scanner, full color high-resolution scanners capable of producing fine real images are widespread nowadays. 
     Currently, most scanners in the market have a user interface capable of reporting to the user as soon as a scanning session is complete so that the user can plan the next task. In general, when a picture or document is being scanned, a user must watch for the end of the scanning session. As soon as a scanning session is complete, a scan completion icon appears on a computer screen through the user interface. Next, the user has to replace the page with a new one and then watch the computer screen again to find out when the scanning session ends. This type of operation is likely to prevent the user from performing other tasks. Alteratively, if the user spends time doing other tasks, the user may miss the end of session notice displayed on the computer screen and leave the scanner in an idle state. Hence, the current method of operating the scanner is quite inconvenient. 
     Some higher-grade scanners now include an automatic document feeder (ADF) so that the user can put a number of pages into a tray and extend each scanning session. At the end of the multi-pager scanning session, an end-of-scanning icon is similarly displayed on the computer screen through the user interface so that the user is notified. However, if the user is occupied with some other tasks at that time, the end-of-scan notice may be missed. Hence, the scanner will still be left in an idle state for quite some time. 
     SUMMARY OF THE INVENTION 
     The invention provides a method of reporting the end of a scanning session to a user. The method includes determining the types of peripheral devices needed to report to the user at the end of a scanning session. When the current scanning task is complete, the selected peripheral devices automatically informs the user of the end of the scanning session. 
     This invention also provides a method of reporting the end of a scanning session to a user. The method includes using a computer to detect all the available peripheral devices for reporting the end of a scanning session. The most suitable peripheral device or devices for reporting end of scanning session to the user are then chosen. After the current scanning session is complete, the end of session notice is signaled to the user via the selected peripheral devices. Next, the computer decides if there is any further scanning task to perform. If there is any other scanning task to perform, the most suitable peripheral device or devices for reporting the end of a scanning session to the user is again chosen. If no more tasks are pending, the reporting system halts. 
     Accordingly, the present invention is to provide a reporting system capable of notifying a user of the end of a scanning session through computer peripheral devices. In addition, the invention is to provide a method of reporting the end of a scanning session to a user in real time so that subsequent scanning operations can proceed immediately with no delays. Hence, idle item of the scanner is greatly reduced. 
     It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWING 
       The accompanying drawing is included to provide a further understanding of the invention, and is incorporated in and constitutes a part of this specification. The drawing illustrates embodiments of the invention and, together with the description, serves to explain the principles of the invention. In the drawing, 
         FIG. 1  is a flow chart showing the steps carried out in an end-of-scanning reporting system according to this invention. 
     
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawing. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. 
     The end-of-scan reporting system in this invention is achieved by appending application programs to the user interface program of a scanner. When the user interface picks up an end-of-scan signal from the scanner, an end-of-scan icon will be displayed on the computer screen as before. However, the system is also capable of reporting the end of scanning session to a user through a user-defined peripheral device or devices so that the user can continue or terminate the scanning task immediately. Hence, machine idle time is reduced. 
     The peripheral devices for reporting the end of a scanning session to a user can be a sound card capable of emitting a sound, the loudspeaker inside a computer system, a network card inside a computer system capable of sending electronic mail to a user&#39;s mailbox, or a data recorder capable of dialing a user&#39;s telephone number, pager number or mobile telephone number. 
       FIG. 1  is a flow chart showing the steps carried out in an end-of-scanning reporting system according to this invention. In step  10 , before a user begins some scanning task, the computer makes a quick search for all the peripheral devices available for reporting end-of-scan to the user. The purpose of making such a search is to ensure that the desired reporting device or devices are present. In step  20 , a suitable peripheral device or devices for reporting the end of scanning session are selected. In general, the most convenient method of reporting is chosen. For example, sound may be broadcast from a sound card or from the on-board computer loudspeaker. Alternatively, the end of scanning notice may be e-mailed to a pre-specified user mailbox. In some cases, a digital data recorder may be used to dial a telephone number, a mobile telephone number or a pager number to notify the user. The scanning task is conducted in step  30 . The scanning task includes scanning a single page or a number of pages using an automatic paper feeder. After the scanning operation, the pre-selected peripheral device or devices are activated to report the end of a scanning session in step  40 . After reporting the end of a scanning session, the system must make a conditioned return. In step  50 , the system detects whether there is a scanning task waiting. If there is a scanning task pending, the system jumps back to step  20  where the available peripheral devices are again detected. Otherwise, if no scanning task is waiting, the system terminates. 
     In summary, one major advantage of this invention is the utilization of existing peripheral device to report the end of a scanning session to a user. Through the notification made by the peripheral devices, the user is able to activate the next scanning task quickly so that idle time of the scanner is greatly reduced. 
     It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
