PERSPECTIVE SKETCHING INSTRUMENT OF STEREOSCOPIC ARTICLE

摘要

PURPOSE: To easily form, enlarge or contract a perspective view of a stereoscopic object by setting a double-pen type tracer to a perpendicularly-held perspection board and arranging a face fixing stand parallel to the perspection board by means of a fixing plate and a clip. ;CONSTITUTION: A perspection board 2 and a face fixing stand 20 are set at the selected drawing position. Then, a face is supported by a jaw mounting table 22 and a head fixing band 26 of the face fixing stand 20, and a visual observation point is determined. An observing eye is further determined by a one-eye shutting door 23. The position of the eye is determined by a height adjusting screw 25. Thereafter, the perspection board 2 is moved back and forth by a clip 28 of a fixing stand moving plate 27 to set the contraction scale of the tracing. The face is subsequently fixed to the face fixing stand 20. A drawing of the stereoscopic object perspectively shown on the perspection board 2 by the one eye is traced by a tracing pen 7 of a double-pen type tracer 61 mounted to the perspection board 2. Consequently, a recording pen 8 interlocking with the tracing pen 7 draws a sketch 5 on a paper 4.;COPYRIGHT: (C)1993,JPO&Japio
