<p>PROBLEM TO BE SOLVED: To prevent a malfunction due to defective connection in a contact part by incorporating the rolling and drawing mechanism of a cable and providing a switch controlling the rolling/drawing of the cable and a cable connector. SOLUTION: A mouse mainbody 1 is connected to an information processor with the cable 5. The cable connector 4 at the tip of the cable 5 is provided with a non-contact point/non-contact interface by light, an electric field and a magnetic field, etc. Therefore, a signal from the mouse mainbody 1 is converted by the cable connector 4 from an electric signal into a light signal and transmitted to the information processor. A cable rolling device 2 for rolling and drawing the cable is provided inside the mouse mainbody 1. Moreover, an operation button 3 for giving an instruction for rolling or drawing the cable is provided at an external side of the mouse mainbody 1. Therefore, the cable is rolled at the time of non-usage and the length of the cable is adjusted to be convenient at the time of usage.</p> |
