Patent ID: 7242974

Claim:
An automatically and manually folded portable wireless terminal having at least a main body and a sub-body installed on the main body so as to be opened and closed, comprising: a first sensor for sensing a complete opening of the sub-body from the main body; a second sensor for sensing a complete closing of the sub-body onto the main body; an opening/closing device for opening/closing the sub-body in accordance with a control of opening/closing of the sub-body and having a motor housed inside of the terminal; a motor overcurrent monitoring section having a current sensing resistor located between a first node and a second node determining an overload condition of the motor based on a difference between a first voltage applied to the first node and a second voltage applied to the second node for monitoring current flow to the motor to determine an overload condition of the motor; and a control device for controlling operation of the motor in accordance with the overload condition as determined by the motor overcurrent monitoring section when complete opening/closing of the sub-body is sensed by the first and the second sensors when the opening/closing device automatically opens/closes the sub-body, and after at least one additional cycle of the motor after an overload condition is determined.
