Title:
DRIVE FORCE TRANSMISSION DEVICE AND UNIVERSAL HEAD DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2011217471
Kind Code:
A
Abstract:

To provide a drive force transmission device allowing reduction in a dead zone amount of a drive system by a simple constitution and control.

The drive force transmission device for driving driven parts includes a first driver and a second driver, drive force transmitted parts which are connected to the driven parts and to which drive forces of the first driver and the second driver are transmitted, and a controller which independently controls the first driver and the second driver. In positions at which the drive force transmitted parts are located differently, a drive force transmission part of the first driver and a drive force transmission part of the second driver transmit the drive forces to the drive force transmitted parts, and when stopping the operating driven parts, the controller stops the first driver and the second driver after driving the first driver in a reverse direction with respect to the drive direction while the second driver is kept driven, and while the drive forces of the first driver and the second driver are balanced.
