1. A distance measurement apparatus, which projects a beam spot onto an object to be measured, a distance to which is to be measured, and performs triangulation by receiving light reflected by the object to be measured, comprising:

  • light-projection means for projecting the beam spot onto the object to be measured;

    a sensor array including an array of a plurality of sensors for receiving and photoelectrically converting the light reflected by the object to be measured;

    integration means for integrating output charges from the sensors of said sensor array;

    charge transfer means for transferring the charges integrated by said integration means, at least a portion of said charge transfer means being coupled in a ring shape; and

    a pair of charge accumulation means, arranged in parallel between said integration means and said charge transfer means, for temporarily storing the charges transferred from said integration means to said charge transfer means.
