Title: Article detector
Inventor: SATO SHINICHI
IPC: G06K7/10
Filed: 1989-10-16
Abstract: PURPOSE:To accurately detect an article by subtracting the lower limit level of a previously obtained background from the quantity of reflected light, regarding less than the lower limit level as a fixed level having no change in the quantity of light to detect the article based on the change in the light quantity. CONSTITUTION:Although the characteristics of OPQ is conventionally plotted as to the relation between a distance L from an article detector and the output of reflected light, the reflection level Vth of the background with a fixed distance L1 is subtracted from the quantity of reflected light and the characteristics of O'P'Q' i.e. less than the lower limit level Vth of an original signal, is regarded as the same P'Q' level. Namely reflected light more than the distance L1 including the background is ignored. Thereby a change in the quantity of reflected light due to the rapid movement of the background can be prevented from being detected as an article and the article can be accurately detected.
