A parallel robot including a movable-section drive mechanism having a parallel mechanism configuration and operating to allow a movable section to perform a three-axis translational motion with respect to a base section, and a wrist-section drive mechanism operating to allow a wrist section to perform a three-axis orientation-changing motion with respect to the movable section. The wrist section includes a first rotary member supported on the movable section and rotatable about a fourth rotation axis different from axes of the three-axis translational motion of the movable section, a second rotary member connected to the first rotary member and rotatable about a fifth rotation axis orthogonal to the fourth rotation axis, and a third rotary member connected to the second rotary member and rotatable about a sixth rotation axis orthogonal to the fifth rotation axis. The third rotary member is provided with an attachment surface to which a tool is attached. The attachment surface is inclined with respect to the sixth rotation axis at a predetermined angle.

A parallel robot including a movable-section drive mechanism having a parallel mechanism configuration and operating to allow a movable section to perform a three-axis translational motion with respect to a base section; and a wrist-section drive mechanism operating to allow a wrist section to perform a rotational motion with respect to the movable section. The wrist-section drive mechanism includes a hollow outer holder connected to the base section rotatably about a first rotation axis; a hollow intermediate holder provided in the outer holder rotatably about a second rotation axis orthogonal to the first axis; a hollow inner holder provided inside the intermediate holder rotatably about a third rotation axis orthogonal to the second axis; a prime mover driving the outer holder to rotate about the first axis; and a transmission member received in the inner holder and linearly movable in a rotationally restrained state along a linear-motion axis orthogonal to the third axis, and connected at one end spaced from the inner holder to the wrist section through a universal joint. The transmission member operates to transmit a rotation of the outer holder about the first axis to the wrist section, and to allow the wrist section to perform a rotational motion about a fourth rotation axis orthogonal to the third axis.

An image processing device generates image data of a projection image displayed on a screen having a color obtained by correcting a color of original data representing an image to be displayed so that the projection image has a desired color. The image processing device includes a storage section adapted to store a spectral reflectivity of the screen, a designation section adapted to designate a type of an outside light in an installation environment of the screen, a correction light determination section adapted to determine a correction light using a spectral distribution of the reflected light obtained based on the spectral reflectivity and a spectral distribution of the outside light, and a color correction section adapted to generate the image data using the original data and data of a spectral distribution of the correction light.

A parallel link robot (10) provided with a base (11), a moving part (12), three links (20a to 20c) coupling the base and the moving part and having respectively single degrees of freedom with respect to the base, and three actuators (13a to 13c) respectively driving the links, each of the links comprised of a drive link (21a to 21c) coupled with the base and two driven links (22a to 22c, 23a to 23c) coupling the drive link and the moving part and parallel to each other, and further provided with a posture changing mechanism (15) which changes a posture of an element (19) attached to the moving part, an additional actuator (13d to 13f) arranged between the two driven links of at least one link in parallel to these driven links, and a power transmission shaft (39) which extends coaxially from the additional actuator and transmits rotational drive force to the posture changing mechanism. Due to this, it is possible to increase the degrees of freedom without reducing the possible region of operation and the acceleration/deceleration performance.
