<p>PURPOSE: A multiple input processing device is provided to perform various inputs by one time touch action and prevent a password from being exposed even tough a number input action is exposed, thereby improving security. CONSTITUTION: A user contact unit(100) comprises a plurality of contact areas. If the contact pressure of a user about a contact area reaches the first critical amount, a contact detector(200) outputs the first output value. If the contact pressure of the user about the contact area reaches the second critical amount, the contact detector outputs the second output value. A signal processing unit(300) processes a predefined signal using the first and second output values. The first critical amount shows the contact of a finger. The second critical amount shows the press by the finger.</p> |
