An optical scanner and an optical scanning type image pickup apparatus and a scanning microscope, both of which prevents an image from being displaced, and a scanning type microscope for preventing enlargement and reduction in the size of a target image by reciprocally traversing an optical means and a sample (scanning surface) relative to each other. A displacement between the optical means and the sample, which is detected by a displacement detector, is differentiated by a differentiating circuit to issue a differentiation signal Sh. A zero-level of the differentiation signal Sh is detected by a comparator, and the comparator issues a timing signal St upon detection of the zero-level. A horizontal sync signal generator generates a horizontal sync signal Hs upon receipt of the signal St. A pixel clock generator feeds a pixel clock signal Cp to an analog-to-digital converter upon receipt of the signal Hs. The analog-to-digital converter, which generates a digital signal by sampling a series of outputs S from a photodetector, carries out sampling at every main scanning line in response to the pixel clock Cp, which is fed at the above timing.
