Abstract: PURPOSE:To reset exactly a microcomputer by less circuit parts by supplying an output of a constant-voltage source to a series circuit of a Zener diode and a resistance, and supplying a partial voltage of the series circuit to a reset terminal of the microcomputer. CONSTITUTION:An output of the first constant-voltage source 21 is supplied to a power source terminal 23a of a microcomputer 23, and an output of the second constant-voltage source 22 is supplied to a voltage source 21 and a series circuit of a Zener diode ZD24 and a resistance 25. A voltage from a connecting point of the ZD24 and the resistance 25 is supplied to a reset terminal 23b of the microcomputer 23. When a power source is turned on, a voltage 31 of the voltage source 22 rises in a prescribed time, and a voltage 32 of the terminal 23a rises a little later than the voltage 31. A voltage 33 of the terminal 23b is held lower by the Zener diode than the voltage 31, and also rises later by a prescribed time. When the power source is off, the operation sequence becomes opposite to that of the time when it is turned on. As a result, the microcomputer 23 becomes strong to noise jumping in from the voltage source 22, and it scarcely occurs that the microcomputer is reset by mistake with respect to a voltage drop of the voltage source 22 due to an instantaneous power failure, etc.

SOLUTION: An insertion amount measurement means 13 measures movement amounts in the insertion direction of a sample 6 and a sample table 7 to be inserted into a sample chamber 4. The sample 6 and the sample table 7 are passed through a sample measurement means 11 to measure their heights and dimensions in the planar direction, dimensions Xs, Ys, Zs of the sample 6 and dimensions Xc, Yc, Zc of the sample table 7 are stored in a memory, and a control device 16 calculates the driving range of a sample moving mechanism 9, within which the sample 6 and the sample table 7 can move without abutting on an objective lens 2, detector 20 or the like based on them. The limit values X1, Y1 and Z1 are defined and stored in the memory 19.  A sample table drive-controlling means compares the present position of the sample moving mechanism 9 with the drive limiting values in the memory 19 and stops the driving, if it exceeds the drive limiting values.
