PURPOSE:To transmit highly accurately rotation in both directions by providing two sets of clutch and brake on a drive shaft to selectively connect and disengage the clutch and brake according to the respective rotational direction. CONSTITUTION:The output of a motor 21 is transmitted from a drive shaft 22 to the input side of a clutch 23 and further to a driven shaft 33 through pulleys 24, 31. Also, on the other hand, the rotation of the drive shaft 22 is transmitted to the input side of a clutch 28 and further to the driven shaft 33 through pulleys 27, 32. Thus, by connecting two sets of clutch and brake to the driven shaft can be transmitted the ration of the drive shaft highly accurately without any play. |
