Pen type optical mouse device and method of controlling the same

A method of controlling a pen-type optical mouse device including a mouse main body, an illumination unit, a light guide, an imaging system, an image sensor, a control means, a transmitting means, a set button, and a contact sensing means, comprising the steps of:

• causing the illumination unit to be on standby so that the illumination unit emits minimal luminosity if there is no input from the exterior for a predetermined period of time (step S10);
• activating the illumination unit to be in a normal operating state if the contact sensing means detects contact pressure, the image sensor detects variations in an image formed thereon, or the set button is selected (steps S20 and S30);
• checking whether a predetermined standby period of time has passed (step S40);
• if the contact sensing means detects the contact pressure, confirming as to whether the detected contact pressure is higher than a predetermined reference pressure (step S50);
• and
• if the detected contact pressure is higher than the predetermined reference pressure, transmitting a writing command to the control means, calculating coordinate values in accordance with movement of the mouse device, processing information on the written letter or drawn figure, and outputting the information to the transmitting means (steps S60 to S80).
