The present invention provides a light emitting device which has high reliability and long service life by suppressing the sealing resin from peeling off the inner edge of the opening of the recess of the housing. The lithium ion battery 11 has internal resistance smaller than internal resistance of the lead acid battery 9 and being charged with the electric power generated by the generator 2. A plurality of plates are disposed in the adapter, plates provided with a central opening, with radially extending slots extending away from the central opening. The system then combines the received lists to produce the selected subset, wherein the selected subset includes all antennas which appear in the received lists of selected antennas. The sums of all trigram path probabilities through each PLU are then calculated as a function of the forward and backward trigram path probabilities. If overlapping by plural guidances using speech, and screen display occurs, the simple display of the guidance lower in priority is executed, and if the guidance falls outside an effective range, the guidance is interrupted, or the guidance during standby-display is not executed.
