ABSTRACT:
An active type range finder apparatus comprises a light projecting element having a base, a lead frame disposed on the base, at least one light emitting member disposed on the lead frame for emitting light to a subject, and at least one control terminal disposed on the base for controlling the light emitting member. A light receiving element is disposed at a base length from the light projecting element for receiving light reflected by the subject. The lead frame and the control terminal of the light projecting element have end portions arranged outside an extension region of the light emitting member in a direction of the base length. When the light emitting member is illuminated, scattered light is prevented from being projected within the extension region of the light emitting member in the direction of the base length, thereby preventing distance measurement errors.
