PURPOSE:To improve the convenience for a user by obtaining an output corresponding to the positional change of a light point from the changing ratio of the position. CONSTITUTION:This light point position detecting apparatus is comprised of a PSD connecting terminal 121, a circuit part 161 constituting a signal processing circuit, a regulating part 162, an output connector 151 and the like mounted on a printed board 131. The PSD connecting terminal 121 is connectable with PSD1, PSD2 PSD3 in various kinds of shapes and with various kinds of effective photodetecting length. The regulating part 162 is adjusted in use by a tool (e.g. driver) 163 so that a meter (e.g. voltmeter) 141 connected to the output connector 151 is in the desired scale in accordance with the PSD connected to the PSD connecting terminal 121. |
