Abstract:
1. An optical pointing device comprising: a light source for irradiating an object; a light guide member for guiding light emitted from the light source and reflected by the object, the light guide member having a top surface including a reflecting surface and a contact surface, the object being in contact with the contact surface, and a bottom surface including a reflecting surface and a part opposed to the light source; an imaging element having a light receiving surface substantially parallel with the top surface of the light guide member for receiving the light guided by the light guide member; a first resin part sealing the imaging element; and a second resin part above the light receiving surface of the imaging element and substantially parallel both with the top surface of the light guide member and with the light receiving surface of the imaging element, the second resin part being in contact with a part of the bottom surface of the light guide member in which no reflecting surface is provided and the first resin part such that the light guided by the light guide member reaches the light receiving surface via the second resin part and then the first resin part.
