<p>A controller device easily kept clean and not affected by magnetism. A light beam from a light emitting element (401) mounted on the device body (101) of a movable device is detected by a light receiving element (402) mounted on the device body (101) through a first optical fiber (431), the wavelength variable mechanism (421) of a controller body (420), and a second optical fiber (432). The wavelength variable mechanism (421) varies the wavelength of the light beam according to manual operation, the wavelength is detected by the light receiving element (402), and a movable mechanism is controllably operated. Since the controller body (420) is not connected to the device body (101) through a conductor, the device is not affected by magnetism, and since an electronic circuit is not mounted on the controller body (420), for example, the controller body (420) can be sterilized with a disinfectant or by fumigation and also can be formed disposable.</p> |
