摘要 |
An end sensor for detecting the end of a thin film stuck to a base plate such as may be used in a printed circuit board manufacturing apparatus. The sensor includes an electroconductive contact member, preferably shaped as a rod or plate, having a tip oriented in a direction at an acute angle to a direction of conveyance of said base plate so as to contact a surface of said base plate and a surface of the thin film. The sensor may be either of the electrostatic capacity type or of the electrical resistance type. |
