Abstract: A printing unit includes a plurality of ink jet parts and an X-axis linear motion mechanism that moves each of the plurality of ink jet parts in the same main scanning direction. The X-axis linear motion mechanism moves the ink jet part involved in printing the workpiece among the plurality of ink jet parts so as to face the surface of the workpiece and moves the remaining ink jet part on the one X-axis linear motion mechanism so as to retreat from the surface of the workpiece. As a result, a printing apparatus that is capable of printing accurately onto the workpiece having a three-dimensional curved surface is provided.

Abstract: A measurement probe of the present disclosure that scans a surface of a measurement object to measure a three-dimensional shape or the like of the surface of the measurement object includes a first movable portion having a stylus, a second movable portion that is connected to the first movable portion to be movable in a Z direction, a third movable portion that is connected to the second movable portion to be movable in the Z direction, a first position measurer that measures a first position of the first movable portion in the Z direction, a second position measurer that measures a second position of the second movable portion in the Z direction, and a third position measurer that measures a third position of the third movable portion in the Z direction. A first relative position is calculated based on the first position and the second position. A second relative position is calculated based on the first position and the third position. The first relative position of the second movable portion with respect to the first movable portion in the Z direction and the second relative position of the third movable portion with respect to the first movable portion in the Z direction are maintained constant.
