MULTI-SHAFT PRESS DEVICE AND IMPRINT DEVICE USING SAME

WIPO Patent Application WO/2014/057589

A1

Provided are a multi-shaft press device that prevents overloading of a drive shaft and an imprint device using the same. An imprint device (100) that uses a multi-shaft press device that drives a pressing member by a plurality of drive shafts is provided with: a plurality of drive shafts (104, 105); sensors (106, 107) for a load detection means that detects a load value for the drive shafts (104, 105); drive parts (102, 103) that drives the drive shafts (104, 105); and a CPU (101) for a control means that controls the drive parts (102, 103). The CPU (101) carries out motion control of the drive shafts (104, 105) for each of the drive shafts (104, 105) on the basis of load values for the drive shafts (104, 105) detected by the load cells of the sensors (106, 107) and target load values indicated in advance for the drive shafts (104, 105). In addition, the CPU (101) carries out motion control for each of the drive shafts such that the target load is maintained for the drive shafts (104, 105) when the load motion control satisfies prescribed conditions.
