Laser range finder is often used for an interface robot to detect people. Sometimes there is a blind spot in its scan area because it scans by infrared. The blind spot causes an error for people detection. In this study, we have considered using a linear unit and moving a laser range finder horizontally. In this paper, we confirmed that blind spot how much is reduced by calculations and experiment. If two persons are walking parallel to the linear unit, the blind spot is reduced about 80 percent by linear unit move to 300 mm. In the case of maximum blind spot, it is reduced about 54 percent. Half of a person in blind spot is found from laser range finder by using linear unit.
