Abstract
A position detector detects a light incident position on one of a plurality of scintillators with a photomultiplier having a number of anodes smaller in number than the scintillators and with a simple circuit configuration. A plurality of anodes are provided in one-to-two or one-to-three correspondence to the plurality of scintillators. An anode receiving photoelectrons is detected from a specific output produced from one of a plurality of first group comparators. Further, either one of two anodes adjacent the detected anode at which the major part of the photoelectrons are received is determined from the outputs of second comparators, whereby one of the plurality of scintillators can be identified.
