  The storage unit 61 includes a ROM, a RAM, a hard disk, and the like, and stores a program 610 of the CPU, image data 611 a configured similarly to the projection image data 611, management data 612, and the like.

  The CPU of the control unit 60 operates as an editing unit by operating according to the program 610. The editing unit edits the image data stored in the storage unit 61 based on the editing information input to the Dutch panel display 12.

(Operation and Effect of Second Embodiment)
According to the second embodiment, the functions and effects (a) to (d) described above can be obtained as in the first embodiment, and image data can be edited. Further, the size of the display unit can be reduced as compared with the first embodiment.

  It should be noted that provisional drawing data corresponding to the assembly process may be used instead of the image data corresponding to the assembly process of the second embodiment. When the operator inputs the editing information of the provisional drawing using a touch pen, an electronic pen, or the like while moving the wire harness over the image displayed on the touch panel display 12, the editing unit of the management device 6 edits the input editing information. The temporary drawing data stored in the storage unit is edited based on the information. Here, the “temporary drawing data” refers to data including drawing information indicating a wiring position of the wire harness and character information indicating a harness assembling operation.

[Third Embodiment]
FIG. 10 is a cross-sectional view illustrating a schematic configuration example of a wire harness manufacturing apparatus according to a third embodiment of the present invention. In the second embodiment, one touch panel display 12 and one remote controller 7 are connected to one management device 6. However, in this embodiment, a plurality of touch panel displays 12 and one remote controller are connected to one management device 6. 7 is connected directly or via a network such as the Internet.

  According to the present embodiment, the following operations and effects are provided. (A) The same wire harness assembly or different wire harness assemblies can be simultaneously manufactured by a plurality of workers. (B) Since the management device 6 knows the start time and the end time of each process for each worker, the management device 6 can know which worker is behind, and determine the number of workers who are behind. You can increase and support them. In addition, productivity can be improved.

  Note that a plurality of touch panel displays 12 may be arranged side by side, and an image for one wire harness assembly may be divided and displayed on the plurality of touch panel displays 12. In this case, it is preferable that there is no gap between the touch panel displays 12.

[Other Modifications]
The embodiments of the present invention are not limited to the above embodiments, and various embodiments can be made without departing from the spirit of the present invention. In the above embodiments, the wiring process of the harness 1, the wiring process of the harness 2, and the wiring process of the harness 3 are switched images, but all the harnesses are displayed with reduced brightness, and Highlighting such as highlighting may be performed so that only the portions related to the harness are displayed brightly, such as only the portions related to the harness are displayed brightly.

  Further, some of the components of the embodiments of the present invention may be omitted without departing from the spirit of the present invention. For example, the image may be switched from the management device 6 without using the remote controller 7. In the first embodiment, a projection image may be directly projected on a screen without using a mirror.

  In addition, steps can be added, deleted, changed, replaced, and the like in the assembling steps of the above-described embodiment without changing the gist of the present invention.

  INDUSTRIAL APPLICATION This invention is applicable to the harness for railroad vehicles, the harness for motor vehicles, the medical harness, the harness in apparatus, etc.
