An original drawing of the wire harness was attached to the surface 2a of the conventional wiring board 2.

The feature of this embodiment resides in that an image necessary for assembling a wire harness is displayed on the wiring board 2 without pasting the full scale drawing. This point will be specifically described with reference to FIG. FIG. 2 is a schematic cross-sectional view showing the internal configuration of the drawing board apparatus for assembling a wire harness.

The wiring board 2 has a two-layer structure. The surface layer side of the wiring board 2 is made of a transparent plate such as a transparent acrylic plate, and the back layer side is made of, for example, a cloth screen 7. Since the surface layer side of the wiring board 2 is a transparent plate, the image projected on the screen 7 can be viewed from the surface 2a side of the wiring board 2. The size of the screen 7 is substantially equal to the size of the transparent plate 4. The screen 7 and the transparent plate 4 are configured by combining different members, but may be configured as an integrated product. For example, it is conceivable that the lower surface 4a of the transparent plate 4 is frosted so that an image is displayed.

An optical projector 6 for projecting an image necessary for assembling the wire harness is arranged below the gantry 3. Further, on the gantry 3, a reflecting mirror 8 for reflecting an image emitted from the optical projector 6 to the screen 7 is arranged along the rear surface 3a. The arrangement positions of the optical projector 6, the screen 7, and the reflecting mirror 8 are determined as follows.

That is, it is assumed that the position and the inclination of the optical projector 6 are set so that the image is irradiated on the screen 7 vertically, and the optical projector 6 is arranged at the position (the position indicated by the two-dot chain line in FIG. 2). . At this position, the reflecting mirror 8 is arranged at a position approximately half the optical path from the optical projector 6 to the screen 7. Thereafter, the optical projector 6 is arranged at a position symmetrical via the reflecting mirror 8 from the position indicated by the two-dot chain line in FIG. The optical projector 6, the screen 7, and the reflecting mirror 8
