<p>PURPOSE:To perform manual scan with high accuracy by detecting the position of an equipment based on reflected light when a non-reflecting part of stripe pattern provided at a guide body coincides with an opaque part at the time of scanning the equipment by a manual operation. CONSTITUTION:A supporting plate 100 which scans a recorder 102 and becomes reference is placed on a recording medium generally, and regulates the scanning direction of the recorder 102. The reflecting part and the non-reflecting part of a mark 101 consisting of the reflecting part and the non-reflecting part provided at the supporting plate 100 are provided with almost the same width. A slit plate 103 provided at a recorder 102 side is provided with a transmission part and a non-transmission part corresponding to the reflecting part and the non-reflecting part of the mark 101. An optical detector 104 detects a light quantity being projected on the mark 101 from a light source 105 passing the slit plate 103, and reflected on the mark 101 passing the slit plate 103. And the recorder 102 is operated manually based on the reflected light when the non-reflecting part of stripe shape and the opaque part coincides, and scan with high accuracy can be performed.</p> |
