A spectrometer slit switching mechanism includes a slit plate having a plurality of entrance slits and exit slits formed at prescribed positions, parallel support rods for supporting the slit plate so as to be movable along the support rods, a screw portion formed on at least one support rod for transmitting forced to the slit plate, and a driving motor for transmitting rotational energy to the support rod provided with the screw portion, wherein the entrance slits are arranged on a line that runs parallel to the direction of movement of the slit plate and the exit slits are arranged on a line that is both parallel to and spaced a prescribed distance from the line on which the entrance slits are arranged. In accordance with this structure, the driving motor is operated in the clockwise and counterclockwise directions to raise and lower the slit plate in order to align a desired entrance slit and exit slit with the light path of the spectrometer. Also, after the desired slits have been positioned and the driving motor is stopped, the slit plate is prevented from moving downwards by the engagement of the slit plate with the screw portion of the support rod, and this eliminates the need for an excitation current to be supplied to the driving motor.
