摘要： A bore measuring system to optically measure the diameter of hole on thin boards, such as printed circuit boards. The bore measuring system of the invention is so contrived as to irradiate a hole to be measured, to project the light through the hole onto the receiving surface of the image sensor and to indicate the diameter of the hole by converting the output from the image sensor, corresponding to the size of the image, into a numerical figure. Unlike the conventional methods, measurement is possible simply by irradiating the hole to be measured without inserting any pin or measuring rod of a hole gauge into the hole, and without projecting the image to be measured onto a screen. Accordingly, the operation is quite simple and the measuring time can be shortened, yet measuring errors can be avoided. Moreover, the automatic display of hole diameter in a numerical value eliminates the reading errors which often occur with conventional methods.
摘要翻译：孔径测量系统，用于光学测量诸如印刷电路板的薄板上的孔的直径。本发明的钻孔测量系统被设计成照射要测量的孔，以将光通过孔突出到图像传感器的接收表面上，并通过转换来自图像传感器的输出来指示孔的直径，对应于图像的大小，成为数字图。与常规方法不同，可以简单地通过在孔中照射要测量的孔而不将孔规的任何销或测量棒插入孔中，并且不将待测量的图像投影到屏幕上。因此，操作非常简单，并且可以缩短测量时间，但是可以避免测量误差。此外，以数值自动显示孔径消除了常规方法常常发生的读取误差。
