Abstract: A blade receives light emitted from a light source and repeats a predetermined periodic motion to scan the front of a vehicle with reflected light of the emitted light. A position detector generates a position detection signal S4 indicating a timing at which a predetermined reference point of the blade passes a predetermined position. Based on the position detection signal S4, a period calculator calculates a period Tp of the periodic motion of the blade. A light intensity calculator receives light-distribution-pattern information S3 to be formed in front of the vehicle and calculates light intensity to be generated by the light source at each time based on the position detection signal S4 and the period Tp. A driver turns on a semiconductor light source so as to obtain the light intensity calculated by the light intensity calculator at each time.

The device further includes a LCD fit into the front face of the casing 10. Outwardly projecting bulges are respectively formed at both sides of the rear face of the casing where fingers of the user gripping the casing 10 placed. Since the fingers and palms are naturally flexed to fit to the dome-like bulges 42L, 42R, the portable electronic device 100 fits comfortably in the user's hands. The operability is hard to be degraded even if the device is vibrated strongly during a game play with the device.
