Abstract
A mark sensor device which is small and convenient in mounting is disclosed. The mark sensor device contains an image data transmitter made of a plurality of optical fibers in a bundle positioned between the object mark and the image sensor, and uses a one-dimensional image sensor. The ends of the plurality of optical fibers on one end of the image data transmitter are arranged in a square shape. The other ends of the plurality of optical fibers on the other end of the image data transmitter are arranged along a line. The one-dimensional image sensor is aligned correspondingly with the linearly aligned ends of the plurality of optical fibers. Accordingly, the light including the optical image of the object mark irradiates the one end of the image data transmitter, travels through the transmitter and comes out from the other end of the transmitter. Thus, the brightness of the light is detected by the one-dimensional image sensor for accurate positioning of the object mark.
