Title: Probe for thickness measuring unit
Inventor: IIGOU MASA
IPC: G01B21/08
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To enhance the follow-up performance of a probe even if a plane to be measured is not flat but curved by suspending the probe from a tubular body using a resilient body thereby engaging the probe vertically to the plane to be measured with a constant pressure. SOLUTION: A tubular probe 5 is arranged coaxially with a tubular body 1 through eight coil springs 6 arranged, at a constant interval, in the circumferential direction and extending radially from the outer circumference of the tubular probe 5 to the inner circumference of the tubular body 1. A magnet 7 is secured to an intermediate part in the longitudinal direction on the outer circumference of the tubular probe 5 and a lead switch 8 is fixed to the inner circumferential surface of the tubular body 1 toward the magnet 7 by means of screws 9. When the probe of a measuring unit is pressed against a plane to be measured, the probe 5 is retracted inward while resisting against the coil spring 6 and the lead switch 8 is turned on by the magnet 7 thus actuating the probe 5.  According to the structure, the probe 5 is held vertically and automatically on the plane to be measured and since the displacement of the spring 6 is kept substantially constant upon retraction of the probe 5, the plane can be measured with accurate reproducibility.

IPC: G03G15/01
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To ensure a highly accurate measurement even when objects having different reflectance are delivered sequentially by arranging the planes including, respectively, the light projecting axis and the light receiving axis of a reflective photoelectric sensor for detecting variation in the center of gravity of a reflected light on a light receiving element in parallel with each other in the moving direction, subtracting a light receiving signal and controlling the moving speed or the interval from the difference of detection time of a border line.

The LED 2 and the split-half PD 5 are arranged in parallel in the moving direction. Since a signal rising/ falling steeply is produced after division, a highly accurate positioning is realized. In order to position a border line, a divided signal is inputted to a comparator and compared with a threshold value. The waveform of a divided output may fluctuate in level due to combination of reflectance of the objects but the shift of positional intersecting the threshold is small when the waveform is steep and the positioning error is reduced.
