Title:
Three-dimensional drive
Document Type and Number:
Japanese Patent JP6105673
Kind Code:
B2
Abstract:
The purpose of this invention is to shine light, using a simple architecture, over a wide area of a three-dimensional space. This three-dimensional drive device (1) has the following: a hollow shaft (10); a motor that rotates said hollow shaft (10) circumferentially; a spur gear (12), the central axis of which coincides with the central axis (11) of the hollow shaft (10), that is located in the center of the hollow shaft (10); a bevel gear (13) that meshes with the spur gear (12) and is located inside the hollow shaft (10); and a spur gear (15), the axis of rotation (14) of which is perpendicular to the central axis (11) of the hollow shaft (10), that meshes with the bevel gear (13) and is located inside the hollow shaft (10). The former spur gear (12) does not move, even when the hollow shaft (10) rotates, but the bevel gear (13) and the latter spur gear (15) revolve by moving in the circumferential direction of the hollow shaft (10) as the hollow shaft (10) rotates. The central axis (11) of the hollow shaft (10) and the axis of rotation (14) of the latter spur gear (15) are perpendicular to each other.
