| 摘要 | PURPOSE:To secure a high resistance to the noise with no abrasion area in a compact and light-weight structure and with no maintenance required by performing the signal transfer with non-contact and with use of the photoelectric conversion coupling at the slip ring part. CONSTITUTION:The control information is transmitted by the cable drum slip ring provided between the control unit fixed on the land and the controlled mobile object. Here, plural units of LED10 are incorporated to the primary side and plural units of photoelectric conversion element 11 are incorporated to the secondary side on the surface opposing to the ring with every circuit. Thus, the photoelectric coupling is formed, and the signal transfer is carried out between the mobile substance and the fixed side control unit with no contact. Thus, the abrasion area is eliminated with a high resistance to the noise in a compact and light-weight structure and with no maintenance required. | ||||||
