in fig2 maintenance and repair operations can be performed on the blood smear preparing device 101 and the sample conveying device 102 from the opened facing surfaces the areas indicated by the diagonal lines in fig2 by moving only the blood smear preparing device 101 in the y direction the stationary part 10 moving part 30 moving part 50 and moving part 70 are described in the example of the embodiment above as only being fixed when the stationary part 10 and the moving part 30 are in the closed condition or when the moving part 30 moving part 50 and moving part 70 are in the closed condition however the present embodiment is not limited to this configuration inasmuch as the stationary part 10 and the moving part 30 may also be fixed in the open condition for maintenance and repair and the moving part 30 moving part 50 and moving part 70 may also be fixed in the opened condition maintenance and repair can therefore be easily performed the present embodiment has been described by way of an example in which both the sample conveying device 102 and the sample image obtaining device 103 can be simultaneously moved in the y direction relative to the blood smear preparing device 101 however the present invention is not limited to this configuration the sample conveying device 102 and the sample image obtaining device 103 may also be moved independently in the y direction relative to the blood smear preparing device 101 in this case for example a guide rail used by the moving part 50 for moving the moving part 50 in the y direction and a guide rail used by the moving part 70 for moving the moving part 70 in the.
