Abstract: <P>PROBLEM TO BE SOLVED: To provide a compact and low-cost raindrop quantity detector for inhibiting an effect due to an external light, such as a sunlight, properly detecting the raindrop quantity attached on a windshield, and preventing a view of a driver from being blocked since a wiper is intermittently controlled, in response to the raindrop quantity.  <P>SOLUTION: A light-emitting section 2 consists of a light-emitting element 21, and a light-emitting prism 22. A light-receiving section 3 consists of a light-receiving element 31, and a light-receiving prism 32. The light-emitting section 2 and the light-receiving section 3 are arrayed horizontally (laterally) on the windshield 5 at an upper part within a vehicle so as to prevent the view of the driver from being blocked. The raindrop quantity detector 1 is mounted and has a small longitudinal dimension. In order to reduce the effects due to the external light, a shape of the light-receiving prism 32 is formed at an angle that is less apt to transmit sunlight, the external light is inhibited by causing only the light-receiving element 31 to receive the light emitted from the light-emitting element 21, and an external light correcting light-emitting element 33 is disposed on the surface of the light-receiving prism 32. Accordingly, the effects due to the external light are eliminated in the light-receiving element 32. The quantity of the light irradiated, scattered and attenuated by the raindrops, attached to the windshield 5, can be detected accurately.  <P>COPYRIGHT: (C)2009,JPO&INPIT
