Document Type and Number:
Japanese Patent JP6031544
Kind Code:
B2
Abstract:
This pressing device includes an actuator, a pressing unit provided on a movable element of the actuator, a movement quantity detector for detecting a movement quantity of the movable element and outputting movement quantity information indicating the movement quantity, and a drive device that moves the pressing unit to press a pressed object by supplying a drive current to the actuator based on the movement quantity information. The drive device controls an operation of the pressing unit using position control processing based on current information indicating the drive current and the movement quantity information. When the speed of the pressing unit is decelerated down to a predetermined lower limit speed, the drive device controls the speed of the pressing unit to be constant based on the current information, and when the current reaches a predetermined current value, determines that the pressing operation is performed.
