Title: Roughness detector
Inventor: OKAMOTO KENJI
IPC: G01B21/30
Filed: 1979-04-26
Abstract: PURPOSE: To improve measurement precision at the time of a measurement of surface roughness by an industrial robot system, etc., by measuring the surface roughness as relative displacement on a circular track of a constant radius drawn at representative measurement points.  
     CONSTITUTION: On the surface of a work material to be measured, adjustment ring 28 is fixed being pressed. When motor 16 of a roughness detector is driven in this state, the turning force of this motor 16 is transmitted to tracer 21 by way of driving axis 15, coupling 18, guide axis 20, and connector 24 to put tracer 21 in circular motion. In addition, since this tracer 21 is pressed against the surface of the work material by spring 19, tracer 21 draws a circular track being displaced to the right and left in the figure according to the unevenness of the surface and the displacement of tracer 21 to the right and left is converted by a differential transformer into an electric signal, which is sent out to a controller (not shown in the figure). This controller judges the roughness and waviness of the surface by empolying the method of pattern recognition.

In order to obtain the copied images of uniform density, negative charges are charged on the surface of the photosensitive plate 11 by a destaticizer 13 and pre-exposure is done by a pre-exposure light source 14, after which positive charging is done by a charger 15, after which copying process is done in an ordinary manner. The charging of the negative charges by the destaticizer 13 is so controlled as to conform to the surface potential of the time when the degree of fatigue of the photosensitive plate 11 becomes balanced by beforehand measuring this surface potential. Hence, even in the case of performing multiple sheets of copying, the surface potentials stabilize and therefore the copied images of even density may be obtained.
