When the height measurement with respect to the end, the rotation signal for rotating the next head (HR, HL) toward the objective lens 5 side is applied to the motor drive unit 10 until the detection signal is applied to the next head (HR, HL), the height of the left and right heads HR, HL according to the output time of the rotation signal, and the relative distance to the left and right heads HR, HL according to the output time of the rotation signal. A control unit 11 for measuring and outputting it as a second display signal; A monitor 8 for displaying an image corresponding to a signal applied from the control unit 11 is provided.

즉, 제어부(11)는 상술한 바와 같이 모터 구동부(10), 위치 검출용 센서(14), 이송대 제어부(12)등을 제어하여 헤드(HR, HL)들의 높이 및 이들 헤드(HR, HL)들 사이의 거리를 자동으로 측정하여 이를 모니터(8)에 디스플레이할 수 있게 되어 사용자는 헤드(HR, HL)들의 높이 및 이들 헤드(HR, HL)들 사이의 거리를 용이하게 알 수 있다는 효과가 있다.That is, the control unit 11 controls the motor driving unit 10, the position detecting sensor 14, the feeder control unit 12, etc. as described above, and the heights of the heads HR and HL and the heads HR and HL. The distance between the heads can be measured automatically and displayed on the monitor 8 so that the user can easily know the height of the heads HR and HL and the distance between the heads HR and HL. There is.
