PURPOSE:To easily change control contents by controlling a course so as to follow the movement of a light beam irradiating a light receiving element. CONSTITUTION:When the light receiving element of a panel unit 6 is irradiated with the light, servo motors 11, 12 are driven and controlled into the state of forward and reverse running or stoppage, and the specified position of the light receiving element is irradiated with the light. Accordingly, according as an irradiated position by a light irradiation device 1 changes, driving wheels 7, 8 are driven, and continue to be driven until the light irradiates the specified position of the light receiving element, and as the result, a truck is moved along the locus of the irradiation of the light by the irradiation device. Thus, the truck can be surely operated through simple configuration, and the control contents can be easily changed. |
