Abstract

PURPOSE:To provide a signal transmitting system, of a non-contact type and having a high band ratio, in which transmission of signals between the inside and the outside of a rotary body is achieved by luminous diodes and light receiving elements, whereby provision of rotary transformer can be rendered unnecessary and installation of the system can be simplified.
