A stator sub-assembly comprises: a coil bobbin which is composed of a cylinder having a winding of a magnet wire therearound, and a terminal block provided with terminal pins connected to lead wires of the winding and coupled stator yokes housing said coil bobbin therein and having a cutout for allowing the terminal block to protrude therethrough. A sensor element, a sensor signal line for outputting a signal from the sensor element, a common wiring line, and a capacitive-coupling-operation bidirectional diode element are disposed at an end of a region on the element substrate in which the pixel regions are arranged. An apparatus for illumination switchover for a microscope of this kind, having switchable illumination in at least two spectral regions, comprises a mechanical positive coupling of the opposite-direction insertion motions of the wavelength-selective filter andor of the light protection filter. The header inscriptions of some or all columns in the data table can also be reduced in horizontal width by selection of a single column. 5 or less and containing not less than 0.
