Abstract
A method of providing the inputting units of the scanner with a foolproof function. Initially, while a specific inputting unit is activated, such as a push button being pushed, the connection between the operation of the scanner and other inputting units is terminated. This terminated connection is not regained until the specific action, which corresponds to the specific inputting unit, finishes. Moreover, an “activation” message can be directly displayed on the scanner while this specific inputting unit is activated, and while the scanner is processing some specific action, this action can be terminated with the function of the scanner and the connection between all inputting units regained as soon as this specific inputting unit is activated again. For any scanner with the foolproof function, while a specific inputting unit is activated, not only a corresponding specific action is performed but also the connection between the performing specific action and all inputting units is controlled.
