PROBLEM TO BE SOLVED: To eliminate the mutual interference of optical communication means and the limitation in layout of communication means to miniaturize the control device of a sanitary apparatus by performing at least one or more optical communications in time division. SOLUTION: This device comprises optical communication means such as photoelectric sensors 2, 3 for detecting the access or sitting of a human body or an optical communication device to another apparatus interlocking with a sanitary apparatus and a microcomputer 1. The microcomputer 1 outputs drive signals to the photoelectric sensor A1 through an output port 4 and to a photoelectric sensor B3 through an output port 5, respectively. The respective receipt signals of the photoelectric sensors 2, 3 are inputted to the input ports 6, 7 of the microcomputer 1. The programs concerning the output port A4 and output port B5 of the microcomputer 1 are formed so that the respective timings of ON are not overlapped. According to this, since one or more optical communication means are communicated in time division, the problem of mutual interference is not caused, nor an excessive space is required. |
