A fishing line guide mechanism for a spinning reel includes a bail arm that has a bail, a first bail arm support member and a line roller. With this arrangement of probes, the probe base thickness can be made greater than the contact pad spacing along the contact line, thereby advantageously increasing the lateral stiffness of the probes. The super lattice layer and the nano-structure can release the stress within the light emitting diode device, and reduce the epitaxy defect, so that the internal quantum effect and the external quantum effect can be increased. Further, a connection recognition protocol to be transmitted from the device when beginning to supply power to the device is transmitted from the switching section. A decoder uses the symbol including multiplex information and decodes the data symbol.
