Title:
TWO SHAFT DRIVING MECHANISM, PICTURE INPUT DEVICE USING THE SAME AND LIGHT PROJECTION DEVICE
Document Type and Number:
Japanese Patent JP3489531
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a two shaft driving mechanism reducing the burden on a motor in a driving mechanism where a driving part which is constituted of a single motor is used and reciprocating movement is executed without installing electric connection between the driving part and a part to be driven and to provide a picture input device using the mechanism and a light projection device.
SOLUTION: The device has a picture input part 200 having a camera 1, a mirror 2 reflecting an image onto the camera 1 and inputting it and motors 3A and 3B rotating the mirror 2 in a horizontal and a vertical directions, a mirror rotation control means 102 controlling the motor 3A and the motor 3B, a computer 101 formed of a picture acquirement means 103 and a picture conversion means 104 and a picture display means 106. The motor 3A and the motor 3B are operated with such a constitution and the mirror 2 is turned to a direction in which an image is picked up. Thus, the picture of the desired direction can be obtained.
