Abstract
A controller which can be kept clean easily and has no influence on magnetism is provided. A light ray from light-emitting element 401 mounted on body 101 of a movable apparatus is detected by light-receiving element 402 mounted on body 101 via first optical fiber 431, wavelength-variable mechanism 421 of controller body 420 and second optical fiber 432. Wavelength-variable mechanism 421 changes a wavelength of the light ray in accordance with manual operation. The wavelength is detected by light-receiving element 402, and an operation of a movable mechanism is controlled. Since controller body 420 is not connected to body 101 via a wire, the controller has no influence on magnetism. Since an electronic circuit is not mounted on controller body 420, for example, controller body 420 can be disinfected with disinfectant or fumigation and also can be formed as a disposable device.
