PURPOSE:To provide an equalizing mechanism for positioning device capable of easily distributing and equalizing the driving force acting on a movable beam driven on a moving rail with an inexpensive structure, and improving the reliability of positioning without loosing the squareness at the drive of the movable beam. CONSTITUTION:This mechanism [s formed of timing belts 5a, 5b laid in parallel to moving rails 2a, 2b on a base 1, timing pulleys 6a, 6b engaged with them, interlocking timing pulleys 8a, 8b installed to the shafts 7a, 7b of the interlocking timing pulleys, and an interlocking timing belt 9 laid between the interlocking timing pulleys. When a movable beam 4 on the moving rails 2a, 2b is driven, the driving force by the rotation of one-side timing belt 5a and timing pulley 6a is equally distributed and transmitted to the other timing belt 5b and timing pulley 6b through the interlocking timing pulley 8a, the interlocking timing belt 9, and the interlocking timing pulley 8b. |
