Mounting target working device

A substrate working device comprising:

• a head unit;
• a flat plate shaped substrate work area in which the head unit performs an operation on a flat plate shape substrate mounting a component thereon and having a flat plate shape;
• a three-dimensional shape substrate work area in which the head unit performs the operation on a three-dimensional shape substrate mounting the component thereon and having a three-dimensional shape as compared with the flat plate shape substrate;
• a conveyance unit including a conveyance path through which the flat plate shape substrate and the three-dimensional shape substrate are carried in, conveyed, and carried out;
• a flat plate shape substrate holder configured to hold the flat plate shape substrate when the head unit performs the operation on the flat plate shape substrate in the flat plate shape substrate work area;
• and
• a three-dimensional shape substrate holder configured to hold the three-dimensional shape substrate and move the held three-dimensional shape substrate along an upward-downward direction, or rotate or incline the held three-dimensional shape substrate when the head unit performs the operation on the three-dimensional shape substrate in the three-dimensional shape substrate work area, wherein
• the flat plate shape substrate work area is an area in which the flat plate shape substrate holder is disposed,
• the three-dimensional shape substrate work area is an area in which the three-dimensional shape substrate holder is disposed,
• the flat plate shape substrate work area is disposed in the conveyance path of the conveyance unit, and
• the three-dimensional shape substrate work area is disposed outside the conveyance path of the conveyance unit.
