<p>PROBLEM TO BE SOLVED: To automatically clear away the dust attached to a roller part and also to easily take the dust out of a mouse main body by preparing a blush part which clears away the dust attached to the roller part and a dust receiving part which is removably attached to the bottom surface of the mouse main body and receives the cleared-away dust. SOLUTION: The blush parts 4a to 4c are prepared near the roller parts 2a to 2c to clear away the dust attached to the parts 2a to 2c. Meanwhile, a hole 6 is formed at the center of the bottom part of a mouse main body 1 and a ball 7 is put into the hole 6. Then a disk-shaped dust receiving part 9 having a hole 8 formed at its center part is removably attached to the bottom part of the main body 1. Thus, the dust attached to the parts 2a to 2c are cleared away by the parts 4a to 4c via the evolutions of the parts 2a to 2c. Then the dust drops down and stored in a groove 10 of the part 9. The dust stored in the groove 10 is taken out of the main body 1 when the part 9 is taken out of the bottom part of the main body 1.</p> |
